EA-18G Program: The USA’s Electronic Growler

Electronic Attack kits clarified; DOT&E Testing report. (Feb 6/12)

The USA’s electronic attack fighters are a unique, overworked, and nearly obsolete capability. With the retirement of the US Air Force’s long-range EF-111 Raven “Spark ‘Vark,” the aging 4-seat EA-6B Prowlers became the USA’s only remaining fighter for radar jamming, communications jamming and information operations like signals interception [1]. Despite their age and performance limits, they’ve been predictably busy on the front lines, used for everything from escorting strike aircraft against heavily defended targets, to disrupting enemy IED land mine attacks by jamming all radio signals in an area.

All airframes have lifespan limits, however, and the EA-6B is no exception. The USA’s new electronic warfare aircraft will be based on Boeing’s 2-seat F/A-18F Super Hornet multi-role fighter, and has 90% commonality with its counterpart. That will give it decent self-defense capabilities, as well as electronic attack potential. At present, however, the EA-18G is slated to be the only dedicated electronic warfare aircraft in the USA’s future force. Since the USA is currently the only western country with such aircraft, the US Navy’s EA-18G fleet would become the sole source of tactical jamming support for NATO and allied air forces as well.

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This article describes the EA-18G aircraft and its key systems, outlining the program, and keeping track of ongoing developments, contracts, etc. that affect the program.

EA-18G: The Platform

While other electronic warfare platforms like the EC-130H Compass Call exist, their slow speed makes their use as tactical jamming aircraft during airstrikes problematic. The most common tactical option for electronic attack, therefore, takes an existing fighter such as the A-6 Intruder (EA-6B Prowler) or F-111 Aardvark (the recently-retired EF-111 Raven, aka. “Spark Vark”), then modifies it via new wiring, changes to the airframe, and additional pods. The price has typically been reduced performance, reduced weapons capability, and sometimes even a larger basic radar signature for the airframe.

The current EA-6B is an excellent example. The good news? Since it’s based on Grumman’s robust A-6 Intruder attack aircraft, it offers excellent range, ample carrying capacity, and efficient subsonic performance. The bad news? Poor self-defense against aerial opponents, a large radar signature, and difficulty keeping up with friendly aircraft traveling at high subsonic cruise speeds.

The EA-18G Growler/ Grizzly has avoided many, but not all, of these typical tradeoffs.

The EA-18 is more than 90% common with the standard F/A-18E/F Super Hornet, sharing its airframe, AN/APG-79 AESA radar, AN/AYK-22 stores management system, and weapons options. The exception is the Super Hornet’s 20mm Vulcan gatling gun, which has been removed from the nose in favor of electrical equipment.

Additional electrical equipment is added throughout the airframe, and Raytheon’s internally-mounted AN/ALQ-227 communication countermeasures system uses a dedicated, omni-directional antenna for signals detection, analysis, and recording. That system works with the plane’s AN/ALQ-99 high and low-band jamming pods, in order to perform complex jamming tasks. Northrop Grumman’s ALQ-218v2 is a digital wideband radio frequency receiver, with selective jamming and geo-location capabilities. It currently equips the EA-18G’s wingtip pods.

The use of pods comes with certain penalties. The increased drag of the external pods, coupled with the shorter range of the F/A-18 E/F base platform vis-a-vis the A-6 it replaces, means that external fuel tanks will be needed. The presence of those fuel tanks on the aircraft’s “wet” pylons, and of the pods on its wingtips and underwing pylons, doesn’t leave much space for other weapons. Despite these limitations, Growlers will be more capable of aerial self-defense than their predecessors. EA-18Gs will typically be armed with a pair of AIM-120 AMRAAM medium range air-air missiles mounted under the engine intakes, and another pair of AGM-88 HARM (High Speed Anti-Radiation) or AGM-88E AARGM (Advanced Anti-Radiation Guided) missiles on underwing stations for destroying enemy radar sites.

Boeing has also surveyed future users of the EA-18G “Growlers” to find out what upgrades they might like to see after the US Navy starts fielding the EA-18G. While the AN/ALQ-99 radar jamming pod has received positive reviews, and will be a critical component of the EA-18G’s initial kit, reports consistently cite it as a maintenance and reliability problem. The US Navy’s EA-18G program manager has said that it might eventually have to be replaced, and the USA’s Next-Generation Jammer program is already in motion to do just that. The EA-18 program is also exploring adding more weapon types and replacing the satellite communications receiver, as part of the budget planning process.

Meanwhile, exports beckon. That would be something of a departure, as the USA has traditionally been the only country to field tactical electronic attack aircraft. As anti-aircraft missiles on the global market become more and more sophisticated, serious players are going to need this kind of capability. The ALQ-99 radar jamming pod is still considered too secret to export, however, so “EA-18 Lite” export versions would reply on the ALQ-218 wingtip pods, and the internally-mounted ALQ-227 system. The APG-79 AESA radar that equips all EA-18Gs could also be used as a jammer, if future software development is forthcoming along those lines. Even so, the removal of the ALQ-99 removes the plane’s most advanced jamming, unless ECM pods from other global sources could be integrated instead, or unless America relents and allows ALQ-99 exports, after fielding its future Next Generation Jammer.

The resulting “EA-18 Lite” combination would be a stronger SEAD (suppression of enemy air defenses) option than the F/A-18F, with more range and available weapons than a full EA-18G, but less jamming than the full EA-18G, and less stealth than the F-35A. EA-18 Lites would be able to identify and geo-locate enemy radars, for instance, and immediately target them with GPS-enabled anti-radar missiles like AARGM. Jamming in low-intensity environments, such as the use of EA-6B Prowlers in Iraq to jam enemy land mine detonation frequencies over key convoys, would also be possible.

Australia has taken initial steps toward buying this EA-18 variant. Their contract specified that 12 of its 24 new F/A-18Fs would have all of the internal modifications required to become an EA-18, if the right equipment is added. The availability of this unique option may yet entice other potential Super Hornet customers to pick Boeing’s plane.

EA-18G: Industrial Program

Naval Air Systems Command (NAVAIR) PMA-265 is the U.S. Navy acquisition office for the EA-18G. Boeing is the prime contractor, building the forward fuselage and wings and conducting final assembly. Northrop Grumman, who designed the YF-17 lightweight fighter that became the F/A-18 family, is the principal subcontractor. They supply the center and aft fuselage and act as the airborne electronic attack subsystem integrator. The Hornet Industry Team will divide key EA-18G component production across Boeing, Northrop Grumman, General Electric (F414 engine) and Raytheon (AN/APG-79 AESA radar) manufacturing facilities.

The EA-18G has faced its share of normal development challenges. A $7 million supplemental contract was required, in order to make its wingtip-mounted AN/ALQ-218 (V)2 radio-frequency receiver systems durable enough to withstand harsh weather. Managing the human interface complexities of going from 4 crew in the EA-6B to just 2 crew in the EA-18G is also an ongoing focus. The EA-18Gs were set to receive their production software and hardware build in July 2007, which is the last major challenge through the end of test and evaluation. Software build 2.0 will fix deficiencies discovered in the first software tape, add 36% more software functionality, and roll in capabilities for communications jamming and Multi-mission Advanced Tactical Terminal systems hardware. The pace of testing provided the team an extra 2 months to incorporate fixes into that software push.

The Growler’s level of commonality with its Super Hornet predecessor helps to keep development costs down, but complex integration is still required for the various electronic components, and testing is still necessary. At the moment, however, the program is slightly under expected cost, as it nears the end of a 5-year system design & development contract.

EA-18G flight testing and Operational Evaluation is taking place at the Navy’s Patuxent River, MD and China Lake, CA test sites, and on Navy carriers, through 2008 and 2009. Fielding is also beginning at NAS Whidbey Island, WA.

At present, industrial partners include:

• Boeing (F/A-18, EA-18G prime contractor)
• GE (F414 engines)
• Northrop Grumman in Bethpage, NY; El Segundo, CA; St Augustine, FL, Baltimore, MD (F/A-18 structures, EW systems and software incl. ALQ-218 and wingtip pods, EW support)
• ITT in Thousand Oaks, CA (ALQ-99 jamming pods, INCANS interference canceling)
• Raytheon in El Segundo, CA; Ft. Wayne, IN; and Largo, FL (APG-79 AESA radar, ALQ-227 CCS)
• Alion Science and Technology Inc. in Annapolis, MD (EM analysis)
• Ball Aerospace, Westminster, CO (MATT antenna)
• Cobham’s Sensor and Antenna Systems division in Landsdale, PA (low band antennas)
• GKN Inc. in St. Louis, MO (complex parts fabrication)
• Harris Corp in Melbourne, FL (data storage devices)
• Nurad in Baltimore, MD (wingtip pod radome)
• Times Microwave in Wallingford, CT (RF/IF coaxial cables)

EA-18G: Numbers & Budgets

The current plan for the EA-18G program is up to 114 planes. That has risen steadily from the original 90, following a slight early decline to 88.

The EA-18G received DoD approval to enter Full Rate Production on Nov 23/09. Initial early deliveries to Fleet Replacement Squadron VAQ-129 have begun, which allows the Navy to begin general aircrew training and develop standard operating procedures. Initial EA-18G Operational Capability was achieved in September 2009 with the US Navy electronic attack squadron VAQ-132 located at Whidbey Island, WA where the Navy’s current EA-6B squadrons are based. The US Navy expects a complete transition of 85 production Growlers to the fleet by 2013.

Budgetary figures below are based on Pentagon documents. All figures are in millions, and deliveries tend to occur 2 fiscal years after orders are placed:

	RDT&E	Procurement	Aircraft	TL
2005	346.5	8.2	0	$354.70
2006	379.7	351.6	4	$731.30
2007	372.3	775.5	8 + 1	$1,147.8
2008	269.4	1525.4	21	$1,794.80
2009	129.7	1594	22	$1,723.70
2010	55.4	1632.4	22	$1,687.80
TL	$1,553.0	$5887.1	78	$7,440.1

FY 2011’s budget wasn’t passed until the following Congress was seated; the request involved $1.787 billion for 22 EA-18Gs, plus long-lead time materials for another 28 in FY 2012. $148.4 million is devoted to RDT&E, and $41.2 million in spares rounds out the $1.977 billion request. The request initially envisioned 12 EA-18Gs, but delays to the F-35 program resulted in increased Super Hornet family orders to cover the gap.

FY 2012’s budget request is for $2.662 billion, covering $2.432 billion for 28 Growlers, $153 million RDT&E, and $77.2 million in spares.

EA-18G: Contracts & Other Developments

In general, this FOCUS article will only cover purchases that refer exclusively to the EA-18G, unless the EA-18G items are specifically broken out, or their inclusion helps make later EA-18 program buys more comprehensible.

As noted above, many procurement items will be shared between the EA-18G and the F/A-18 E/F Super Hornets, on which the platform is based. DID’s Spotlights on the MYP-II (FY 2005-2009) and MYP-III (FY 2010-2014) multi-year Super Hornet contracts cover all airframes and integration from 2005-2014. Fleet support costs are also part of the F/A-18E/F contracts, due to aircraft commonality; while common “Government-Furnished Equipment” items like APG-79 radars, GE’s F414 engines, etc. are bought through separate contracts of their own.

“Electronic Attack Kits” include the AN/ALQ-218 wingtip pods, and all of the unique internal electronics and gear that make the plane an EA-18G instead of an F/A-18F. What they do not include, is the AN/ALQ-99 pods carried underneath the Growlers. Those are simply moved over from retiring EA-6B Prowlers, following minor hardware and software compatibility modifications.

Unless otherwise specified, all awards are made to Boeing subsidiary McDonnell Douglas Corp. in St. Louis, MO, and/or are awarded by the Naval Air Systems Command (NAVAIR) in Patuxent River, MD.

FY 2012

Feb 1/12: A $132.8 million contract modification, exercising an option for 12 sets of EA-18G airborne electronic attack kits and the associated non-recurring engineering, as part of Lot 36 Full Rate Production. This figure is very much in line with last year’s order, vid. June 29/11. Note, too, the use of “Lot 36 FRP”. The EA-18G hasn’t had time for nearly that many production lots, but the Hornet airframe has. EA kits comprise the various specialized technologies that distinguish the EA-18G from the F/A-18F.

Work will be performed in Baltimore, MD (41.1%); St. Louis, MO (36.3%); Bethpage, NY (19%); and Fort Wayne, IN (3.6%). Work is expected to be complete in September 2014 (N00019-09-C-0086).

Jan 17/12: The Pentagon releases the FY2011 Annual Report from its Office of the Director, Operational Test & Evaluation (DOT&E). The EA-18G is included, and the news is pretty good:

“Emerging 2011… results suggest the EA-18G remains operationally effective, while operational suitability has notably improved…. the EA-18G system met the threshold for operational availability. The point value for reliability met the 14-hour threshold, but the 80 percent confidence level (lower bound) fell below the threshold. Maintainability did not meet the threshold level but only by a small measure, and built-in test performance was largely improved since IOT&E. Maintenance documentation was improved from IOT&E, but Navy personnel still rated the system as difficult to use and incomplete in some areas. DOT&E analysis of test data is still ongoing and a complete assessment will be published in early FY12.”

Nov 1/11: Northrop Grumman Systems Corp. in Bethpage, NY receives a sole source, firm-fixed-price, maximum $26 million contract from the US Navy for airborne electronic attack spares and radio frequency switches. Since much of this equipment is common to the EA-18G and EA-6B platforms, the Growler’s share isn’t entirely clear, but it will be growing over the performance period.

Work will be performed in Bethpage, NY and Linthicum, MD, running until July 31/14 and paid for by FY 2012-2014 Navy Working Capital funds. The US Defense Logistics Agency Aviation Strategic Acquisitions group in Philadelphia, PA manages the contract (SPM4AX-12-D-9401).

Oct 19/11: During an interview with Australia Broadcasting Corporation Radio, Labor government defense minister Stephen Smith discusses the possibility of turning 12 of Australia’s Super Hornets into EA-18G Growler electronic warfare fighters, whose conversion price tag is described by the interviewer as “upwards of A$ 300 million.” The EA-18G recently saw their its combat use over Libya, and:

“We’ve just started the process of making a judgment about whether acquiring [them] would be in our national interest or our national security interest…. we took the sensible precaution of wiring up half of our Super Hornets for this potential. But it is a very expensive capability. We’re just going through the process…. this possibility would come as no surprise to our friends and neighbours in the region. It’s been on the public record before and part of the [2009 Defence] White Paper.”

The minister does not contradict the price figure, and in a related ABC TV interview, he mentions costs of “hundreds of millions.” The minister also implied that further delays or issues with the F-35A could make an EA-18 conversion more likely, as a way to strengthen Australia’s air capability in the interim. ABC radio transcript | ABC24 TV news transcript.

Oct 3/11: Boeing discusses recent changes to the Super Hornet family’s wing frame, which sharply reduced the number of parts, and the amount of assembly time. Modern manufacturing technologies let them replace a large number of components from different subcontractors, with a machined 1-piece component that makes up much of the wing frame. That reduces rework and labor assembly time, while improving the wing’s reliability. Boeing (incl. video).

FY 2011

July 29/11: Northrop Grumman Systems Corp. in Bethpage, N.Y receives a $54.8 million, 3-year indefinite-delivery/ indefinite-quantity contract for engineering, technical and program support services for ongoing development & maintenance of EA-6B operational flight software, EA-6B “unique planning component,” and EA-18G operational flight software. Both aircraft types are handled by the Navy’s Airborne Electronic Attack Integrated Product Team.

Work will be performed in Point Mugu, CA (90%), and Bethpage, NY (10%), and is expected to be complete by July 2014. $200,000 will expire at the end of the current fiscal year, on Sept 30/11. This contract was not competitively procured pursuant to FAR 6.302-1 (N68936-11-D-0028).

July 9/11: VAQ-132’s EA-18G Growlers all return to their home base at NAS Whidbey Island, WA, after completing an 8-month land-based deployment to Iraq and Libya. Deployed EA-18Gs now include VAQ-141 aboard the USS George H.W. Bush [CVN 77], marking the Growler’s first sea-based deployment. They’re part of Carrier Air Wing 8, operating in the Mediterranean and Persian Gulf. Boeing mentions that “a third electronic attack squadron, VAQ-138, recently deployed to a land-based location,” which could mean that they’ve replaced VAQ-132 over Libya.

By the end of 2015, 3 expeditionary squadrons and 10 carrier-based squadrons are scheduled to transition from the EA-6B Prowler to the EA-18G Growler. US NAVAIR | Boeing.

June 29/11: A $130 million firm-fixed-price contract modification for 12 airborne electronic attack kits and associated engineering, as part of EA-18G orders in Super Hornet family full rate production Lot 35. Note that this isn’t ordering airframes, or radars, or engines – just the electronic attack equipment. Some simple division should help readers get a better sense of how much “government furnished equipment” can add to the price of a fully functional fighter, especially a very specialized plane like the EA-16G.

Work will be performed in Baltimore, MD (43.3%); St. Louis, MO (33.3%); Bethpage, NY (17.8%); and Fort Wayne, IN (5.6%), and is expected to be completed in July 2013 (N00019-09-C-0086).

May 25/11: The Navy’s new AGM-88E AARGM radar-killer missile successfully completes its 1st EA-18G Growler test, during a captive-carry flight at China Lake, CA. Growler work will continue, in parallel with the ongoing AARGM Integrated Test & Evaluation phase using FA-18C/D Hornets.

The test squadrons have also used Super Hornets, and Cmdr. Chad Reed, deputy program manager for Anti-Radiation Missiles within the Direct and Time Sensitive Strike program office (PMA-242), says that F/A-18E/F Super Hornet and EA-18G Growler testing since November 2010 totals 25 flight hours, compared to over 150 flight-hours on F/A-18C/D Hornets. US NAVAIR.

March 30/11: A $40 million awarded fixed-price-incentive-fee contract modification for one-time engineering services in support of the F/A-18E/F and EA-18G’s next generation advanced mission computer system.

Work was performed in Bloomington, MN (53.7%), Baltimore, MD (33.3%), and St. Louis, MO (13%). This is a retroactive contract, with the Pentagon noting that “Work was completed in December 2010” (N00019-09-C-0019).

March 30/11: Northrop Grumman Systems Corp. in Bethpage, NY receives an $8.6 million cost-plus-fixed-fee, indefinite-delivery/ indefinite-quantity contract modification to provide engineering and software services in support of EA-6B Prowler and EA-18G Growler aircraft. Services will include design, development, integration, test and distribution of the operational flight programs, flight test and aircraft integration support, and engineering support to transition the electronic attack mission from the EA-6B to the EA-18G.

Work will be performed at the Naval Air Warfare Center Weapons Division in Point Mugu, CA, and is expected to be complete in December 2011. The Naval Air Warfare Center Weapons Division at Point Mugu, CA manages the contract (N68936-08-D-0026).

March 20/11: The EA-18G makes its combat debut during opening strikes against Libyan air defenses, using the 5-plane Scorpions squadron that had been deployed to Al-Asad in Iraq (vid. Feb 1/11). They’re currently operating out of NAS Sigonella and Aviano Air Base, in Italy. US Navy | CNN.

Feb 3/11: A January 2011 report by the Pentagon’s Director of Operational Test and Evaluation (DOT&E) rates the EA-18G as “operationally effective,” (can perform its mission), but not “operationally suitable” (supportable in a sustainable way). Software stability in particular is seen as an ongoing issue.

The US Navy disagrees. They say it’s both effective and suitable, and argue that the DOT&E included items outside the scope of the program for its 2010 report. “None of the anomalies were showstoppers,” says the Navy, and scheduled testing in early 2011 should tell them how many of the remaining issues are still a problem. Aviation Week | See also past DOT&E 2009 report (2010 release, PDF).

Feb 1/11: DLA Aviation discusses the challenges it has faced working to support the EA-18G’s 1st expeditionary deployment, at Al-Asad AB, Iraq. VAQ-132’s deployment began in mid-November 2010, but a 2009 change placed them on land, instead of on the USS Carl Vinson (CVN-70).

The removal of the carrier’s inherent support infrastructure was just the first of many issues as DLA planned for the land-based deployment. Another was an expected increase in flight hours from 30 hours per month, to over 100 hours. Having about 30,000 parts in common with the F/A-18F helps, as DLA also supports Super Hornets in theater. Even so, a delay in receiving Navy requirements forced DLA to do a lot of expediting, finding lateral support, and asking for spot buys, in order to ensure 100% inclusion of the items they believed they’d need to keep the lanes running. In the end, the pack up kit of consumable parts for the 5 EA-18Gs included about 900 of the most needed items.

Nov 29/10: A $6.7 million firm-fixed-price delivery order under the basic ordering agreement. Boeing will provide operational level (front line, not depot-level) support equipment that’s specific to the EA-18G, and not common to other Super Hornet aircraft. This will help new EA-18G aircraft squadrons stand up with everything they need.

Work will be performed in St. Louis, MO, and is expected to be complete in November 2012. All contract funds will expire at the end of the current fiscal year. The Naval Air Warfare Center Aircraft Division in Lakehurst, N.J. manages this contract (N68335-10-G-0012).

Nov 19/10: Aviation Week, “Directed Energy Weapons Attack Electronics” :

“The lightning rod for rapid fielding of directed energy (DE) weapons and advanced sensors will be the military’s next-generation jammer programs that exploit technologies like active electronically scanned arrays (AESAs) antennas and high-power microwave (HPM) capabilities, say senior U.S. government and industry officials at the 13th Directed Energy Conference.

Radars on the Lockheed Martin F-22 and F-35, and Boeing F/A-18F and EA-18G, already have the potential to fire focused beams of energy as soon as funding is available to develop the necessary advanced algorithms.”

FY 2010

Aug 6/10: A $5.9 million ceiling priced delivery order for repairable support for advanced electronic attack components of the EA-18G aircraft.

Work will be performed in Baltimore, MD (84%); Bethpage, NY (8%); Whidbey Island, WA (3%); Melbourne, FL (2%); St. Augustine, FL (2%); and Fort Wayne, IN (1%). Work is expected to be complete by January 2011. The Naval Inventory Control Point in Philadelphia, PA manages this contract (N00383-06-G-006B, #0012).

May 28/10: Raytheon Network Centric Systems in Fort Wayne, IN received an $8.7 million cost-plus-fixed-fee, indefinite-delivery/ indefinite-quantity contract to provide performance-based engineering services in support of the EA-18G’s AN/ALQ-227 communication countermeasure systems. Support services will include systems engineering, testing, product assurance, logistics, training, and production.

Work will be performed in Fort Wayne, IN, and is expected to be complete in May 2015. This contract was not competitively procured, pursuant to FAR 6.302-1, by the US Naval Air Warfare Center Weapons Division in China Lake, CA (N68936-10-D-0013).

May 24/10: A ribbon-cutting ceremony marks Hangar 5’s recapitalization at Naval Air Station (NAS) Whidbey Island, WA. The $55.8 million design-build project began in January 2008. The improved facility will house 5 EA-18G Growler squadrons, the Electronic Attack Weapons School and Commander, Electronic Attack Wing, U.S. Pacific Fleet. US Navy photo release.

April 1/10: SAR – more EA-18Gs. The Pentagon releases its April 2010 Selected Acquisitions Report, covering major program changes up to December 2009. The USA wants more EA-18Gs:

“EA-18G – Program costs increased $2,901.0 million (+33.5%) from $8,649.1 million to $11,550.1 million, due primarily to a quantity increase of 29 aircraft from 85 to 114 aircraft (+$2,342.5 million) and associated schedule and estimating allocations (+$7.8 million), and an increase in support costs for 26 expeditionary aircraft associated with the quantity increase (+$547.6 million).”

March 5/10: The US Navy’s EA-18G Fleet Replacement Squadron trainers in VAQ-129 graduate Class 09-08, the first class of 5 “Category 1” EA-18G aircrew that come straight from flight school. The squadron had previously trained veteran EA-6B pilots from VAQ-132 and VAQ-141, where the new “Cat 1s” will be assigned.

The 9-month course included a wide range of activities, from computer-based training, to lectures, simulators, and flights. Flights include day and night formation flying, basic radar mechanics, air-to-air fighter tactics, airborne electronic attack, in-flight refueling, and day and night carrier qualification. The Airborne Electronic Attack portion of the syllabus is new, and is being refined with each successive class.

Unlike the EA-6B, where student pilots carrier qualify with a veteran instructor in the right seat, the CAT 1’s must take the Growler to the boat as a “crew solo”: a student in the front, and a student in the back. US Navy.

Feb 12/10: The “Shadowhawks” of VAQ-141 are declared “Safe for Flight” in their new EA-18G Growlers at Naval Air Station (NAS) Whidbey Island, WA, following an 8-month training period under fleet replacment squadron VAQ-129. The Shadowhawks are the 2nd operational squadron to achieve this, qualification after the “Scorpions” of VAQ-132. Both squadrons had previously flown EA-6B Prowlers. US Navy.

Jan 12/09: Wyle Laboratories, Inc. in Huntsville, AL received a $10.8 million cost-plus fixed-fee, indefinite-delivery/ indefinite-quantity contract to provide airborne electronic attack engineering support for the EA-6B, EA-18G, and other advanced electronic attack derivatives at the Naval Air Warfare Center Weapons Division (NAWCWD) in Point Mugu, CA.

Work will be performed at NAWCWD, Point Mugu, CA (85%); NAWCWD, China Lake, CA (5%); Naval Air Warfare Center Aircraft Division, Patuxent River, MD (5%); and Naval Air Station, Whidbey Island, WA (5%). Work is expected to be complete in January 2015. This contract was not competitively procured pursuant to Federal Acquisition Regulations by NAWCWD in China Lake, CA (N68936-10-D-0014).

Feb 3/10: Ranking House Armed Services Seapower subcommittee Rep. Todd Akin [R-MO] publicly supports building more Super Hornet family aircraft, and advocates a multi-year buy approach for the F/A-18E/F and EA-18G, similar to the 2005-2009 contract. In Rep. Arkin’s release, he says that:

“I remain concerned that the Department of Defense is not taking the Navy’s strike fighter shortfall seriously…. The Super Hornet is an active production line, and is dramatically cheaper than the JSF, which may not deliver anywhere close to on time…. In this case, a multi-year procurement could save hundreds of millions of dollars, but the DoD seems to have their head in the sand. Secretary Gates mentioned that he thinks we need to have a 10% savings before we use a multi-year agreement. However, the Congress already gave DoD the authority to use a multiyear in this situation, even if the savings is less than 10%.... A multiyear procurement could save nearly half a billion dollars over the next few years. To not pursue that savings is just irresponsible.”

Jan 7/10: Media reports surface that Defense Secretary Robert Gates has ordered a delay in the Lockheed Martin Corp. F-35 program, cutting planned purchases from 2011 – 2015 in order to fund research, development, testing & evaluation (RDT&E). In FY 2011-12, the US Navy will reportedly compensate for the implicit F-35C delays, by buying another 24 Boeing Super Hornet family planes for $2.4 billion.

A Bloomberg report confusingly mentions “F/A-18E/F planes that are capable of jamming enemy radar,” which could indicate the addition of 24 EA-18Gs. The Growlers would help to fill immediate gaps in airborne jamming, which is in high demand. They would also help maintain long-term fighter numbers with aircraft that would remain operationally viable farther into the future than standard Super Hornets.

Work will be performed in Baltimore, MD (46.5%); Bethpage, NY (22.7%); St. Louis, MO (13.5%); Melbourne, FL (5.5%); Fort Wayne, IN (3.7%); Thousand Oaks, CA (3.7%); Wallingford, CT (2.6%); Nashua, NH (1.1%); and Westminster, CO (0.7%), and is expected to be complete in December 2012.

Nov 30/09: A $9.4 million modification to a previously awarded firm-fixed-price contract (N00019-04-C-0014) to incorporate engineering change proposals 6251 and 6251R1 and convert 22 Lot 33 F/A-18F aircraft to EA-18G aircraft. Work will be performed in St. Louis, MO (62%); El Segundo, CA (36%); and Mesa, AZ (2%), and is expected to be complete in September 2011.

EA-18Gs start out as F/A-18F base airframes, then receive additional wiring and other changes, before the full airborne electronic attack set is integrated.

Nov 23/09: The US Department of Defense approves Full Rate Production (FRP) of the EA-18G Growler. The EA-18G program now can proceed from Low Rate Initial Production to quantities of 20+ aircraft per year, as budgeted in FY 2010.

The EA-18G achieved Initial Operational Capability in September 2009 with US Navy electronic attack squadron VAQ-132, based at Naval Air Station Whidbey Island in Washington State. Boeing release.

Oct 29/09: A maximum $51 million firm-fixed-price, sole source contract for 23 line items in support of the EA-18G’s FY 2010 program. There was originally 1 proposal solicited with 1 response, and the date of performance completion is Dec 31/12. The Defense Logistics Agency Philadelphia, in Philadelphia, PA manages this contract (N00383-06-D-001J-TH05).

Oct 28/09: President Obama signs the FY 2010 defense budget into law. That budget provides funding for 22 EA-18Gs, and Congress increased related F/A-18 E/F Super Hornet purchases from 9 to 18. White House | House-

FY 2009

July 28/09: The US Department of Defense releases the EA-18G Growler’s initial operational test and evaluation (IOT&E) findings, which recommended it for use in the fleet and gave it the best rating of “operationally effective, operationally suitable.” Effectiveness refers to mission performance evaluations, while suitability focuses on maintainability and reliability.

The initial EA-18G combines 2 fielded systems, in the F/A-18F airframe and the same Improved Capability III (ICAP III) electronic warfare suite used on current EA-6B Prowlers. That lowers risk, but it’s still a new combination. As it happens, software anomalies were discovered during the IOT&E process. The EA-18G team is developing a software update release, to be implemented during the normal verification and correction of deficiencies (VCD) period later this year. US Navy NAVAIR.

July 1/09: A $27.9 million modification to a previously awarded firm-fixed-price contract (N00019-09-C-0086) for additional time-critical parts in support of EA-18G Full Rate Production.

Work will be performed in St. Louis, MO, and is expected to be complete in September 2009. The EA-18G has a set manufacturer, so this contract was not competitively procured.

June 8/09: EA-18G Grizzly. Gannett’s Navy Times reports that the EA-18G’s “Growler” moniker sounded too close to the EA-6B’s “Prowler”, so the EA-18G will now be known as the “Grizzly” in operational situations, in order to avoid any confusion or mistakes. Presumably, the standard NATO “G” phonetic alphabet call of “Golf” was seen as somewhat lacking. “Growler” will remain the EA-18G’s primary moniker outside of carrier decks.

The Navy does something similar with the F/A-18F, which is colloquially called the “Rhino”. F/A-18Fs were the first Super Hornets to get new and improved AN/APG-79 AESA radars in their nose cones.

April 29/09: Northrop Grumman Systems Corp. in Bethpage, NY received a $9.9 million cost plus fixed fee contract for various products, and 73,571 hours of engineering services, in support of the EA-18G Airborne Electronic Attack (AEA) Integrated Product Team. The firm will provide assistance with design, development, integration, test and distribution of Electronic Attack Unit software, technical evaluations, and testing of changes; and will support follow-on test and evaluation integration and test.

Work will be performed at Point Mugu, CA, (85%); Bethpage, NY, (10%); and China Lake, CA, (5%), and is expected to be completed in April 2012. This contract was not competitively procured pursuant to the FAR 6.302-1. The Naval Air Warfare Center, Weapons Division in China Lake, CA manages this contract (N68936-09-D-0026).

Feb 27/09: Australia is pre-wiring 12 of its planned 24 F/A-18F Super Hornets, in order to allow future conversions to EA-18 Lite status. The additional cost for the pre-wiring on the production line is A$ 35 million, out of an order now cited as A$ 6.6 billion. Completing that fit out to “Growler Lite” status is expected to involve an additional A$ 300 million, with the go/no-go decision set for 2012.

Characteristically, the new Labor Party government’s release ends with a shot at the procurement policies of the previous Liberal Party government:

“If the Howard Government had taken a more prudent approach in making the Super Hornet decision rather than rushing to fill their impending air combat capability gap, they may have realised that this was a more effective approach to take.”

Feb 25/09: EA-18L Growler Lite? Media reports indicate that an export variant will soon be offered. The ALQ-99 radar jamming pod is still considered top secret, even though some of its hardware is a generation or two behind, and the program to field its replacement Next Generation Jammer has already begun.

Instead, export versions would reply on 2 components. Northrop Grumman’s ALQ-218v2 is a digital wideband radio frequency receiver, with selective jamming and geo-location capabilities. It currently equips the EA-18G’s wingtip pods, and the US Navy’s EA-6B Prowlers. Raytheon’s internally-mounted ALQ-227 communication countermeasures system makes use of a dedicated, omni-directional antenna for signals detection, analysis, and recording; but the removal of the ALQ-99 pods would remove its complex jamming functions, unless a foreign-made pod could be integrated with it instead. The export EA-18 would also ship with Raytheon’s APG-79 AESA radar, which equips existing EA-18Gs and F/A-18E/F Block II aircraft, and could be used as a jammer with additional software development.

The combination would be a strong SEAD (suppression of enemy air defenses) option, albeit one with less stealth than the F-35A. It would allow EA-18 Lites to geo-locate identified radar emitters, for instance, then target them with GPS-enabled anti-radiation missiles like AARGM. These capabilities could also be supplemented by foreign radar jamming pods bought on the international market, in order to create an aircraft with capabilities comparable to the EA-18G. Flight

Feb 25/09: Raptor Killer. Stephen Trimble photographs a kill decal on EA-1, the 1st of 2 Lot 27 F/A-18Fs converted into flying EA-18G prototypes. Turns out, the kill decal is a F-22A Raptor, making EA-1 one of the few aircraft to ever achieve this feat:

“I did learn the EA-18G kill was courtesy of a well-timed AIM-120 AMRAAM shot. And I learned the simulated combat exercise took place at Nellis AFB. How the EA-18G escort jammer got the shot, and whether its jamming system played a role in the incident were not questions the pilot was prepared to answer.”

Dec 23/08: An unfinalized contract with a ceiling price of $50.3 million, to buy time critical parts (TCP) for 22 Full Rate Production (FRP) Airborne Electronic Attack systems. They will be fitted into the FY 2009 buy of 22 EA-18Gs. Work will be performed in St. Louis, MO and is expected to be complete in May 2009. This contract was not competitively procured (N00019-09-C-0086).

Dec 23/08: A $21.2 million firm-fixed-price, cost plus fixed fee modification to a previously awarded delivery order contract (N00383-06-D-001J) for integrated contractor engineering, logistics, and equipment to support the EA-18G.

Work will be performed in Bethpage, NY (60%) and St. Louis, MO (40%), and is expected to be complete in December 2010, but $7.2 million will expire at the end of the current fiscal year.

Dec 1/08: A $95 million delivery order under a previously-awarded Performance Based Logistics contract for spares in support of the EA-18G Growler. Work will be performed in St. Louis, MO (40%), and El Segundo, CA (60%), and is expected to be complete by September 2011. The Naval Inventory Control Point manages this contract (N00383-06-D-001J-TH00).

Nov 30/08: Aviation Week reports that the USAF (F-35A) and US Marines (F-35B STOVL) are moving toward plans that would let them convert F-35s into electronic attack aircraft that would serve alongside the EA-18Gs. Plans aren’t yet firm, but officials apparently hope that the F-35’s extremely advanced electronics and sensors, combined with parallel efforts like the Next Generation Jammer program, will allow the planes to be used as “EA-35s” without requiring dedicated and modified airframes.

In a world where small pods that can clip onto any fighter in the fleet have completely replaced dedicated “RF-” reconaissance fighters, the idea of a parallel development for “EA-” fighters does not seem ridiculous. See DID’s October 2005 “Supersonic SIGINT…” for more. Nevertheless, any program to create a full EF-35 capability will face challenging technical questions. An EW specialist interviewed by Aviation Week explained some of them:

”...if it’s in an external pod, [the extra radar reflectivity] will give away the aircraft’s location. Yet, if you put the guts of an NGJ into the weapon bays of a single-engine single-generator aircraft in order to maintain all-aspect stealth, you are rapidly going to run out of available power to run it…. [And] If the aircraft has to maintain all-aspect stealth, then how can you do the necessary jamming…. [Plus,] electronic attack is one area where size does matter… an EB-52 carrying large-aperture, active electronically scanned array radar with the output of an electronic techniques generator routed through it can be a very long-range electronic weapon. [Large ilitary aircraft of many types] are also possible platforms for the Next-Generation Jammer. Finally, unmanned aircraft of the [RQ-4] Global Hawk and [MQ-9] Reaper size could have the necessary size, power and payload.”

Nov 21/08 Boeing delivers its first EA-18G Growler maintenance trainer to Whidbey Island Naval Air Station, WA, 2 weeks ahead of schedule. Boeing delivered the first fleet EA-18G and an EA-18G aircrew trainer to VAQ-129 in June 2008.

The EA-18G Maintenance Trainer (EAMT) is a set of 3 devices. One is a hardware mockup that represents the gun bay and pallet, and the second represents a wingtip pod. The mockups are used to support training on installation and removal procedures for the Growler’s unique equipment. The third device is the Visual Environment Maintenance Trainer, where student interacts with the trainer via a fully replicated cockpit and displays to test and troubleshoot, while an instructor/operator station controls the simulations and 2 touch-screen displays provide graphical representations of the aircraft and support equipment. Boeing release.

Nov 4/08: NAVAIR announces that the EA-18G Growler has moved to Operational Evaluation (OpEval), following initial sea trials on the USS Dwight D. Eisenhower [CVN-69] from July 31/08 through Aug 5/08.

Oct 30/08: A $6.5 million modification/ delivery order under a previously awarded contract (N00383-06-D-001J, #0004) to purchase repair-of-repairables support for the E/A-18 G Growler. Work will be performed in St. Louis, MO and the contract will end when the fiscal year does on Sept 30/09. The Naval Inventory Control Point in Philadelphia, PA manages this contract.

Oct 2/08: The Kitsap Sun reports that Air Test and Evaluation Squadron 9 has been using the USS John C. Stennis [CVN 75] as part of the EA-18G’s Operation Evaluation (OpEval), which includes carrier night landings and tests of the new electronic components’ durability under the controlled crash conditions of carrier landings.

Cmdr. Al Bradford, the squadron’s electronic warfare branch head, described this effort as “the final exam for the aircraft.”

Sept 18/08: A $13 million ceiling priced modification to delivery order under a previously awarded contract (N00383-06-D-001J, #0004) for support equipment and engineering support for the EA-18G Growler aircraft. Work will be performed in St. Louis, MO and is expected to be complete by April 2010. This contract was not competitively procured by The Naval Inventory Control Point.

Aug 5/08: A $659.2 million modification to a previously awarded firm-fixed-price contract (N00019-04-C-0014), exercising the option for 13 F/A-18Fs and 3 E/A-18G aircraft for the U.S. Navy. Note that these are just airframes, without key components like radar, engines, and other associated equipment. The full cost of the delivered aircraft is significantly higher.

Work will be performed in St. Louis, MO (28.7%); El Segundo, CA (25%); Goleta, CA (8.6%); Clearwater, FL (2.3%); Greenlawn, NY (2.1%); Burnsville, MN (2.1%); Johnson City, NY (2.1%); Brooklyn Heights, OH (2%); Vandalia, OH (2%); Grand Rapids, MI (2%); South Bend, IN (2%); Mesa, AZ (1.8%); Fort Worth, TX (1.8%); and at various locations across the United States (17.5%), and is expected to be complete in January 2012.

Aug 5/08: The EA-18G Test Team at NAWCWD China Lake conducts its first AGM-88 High-Speed Anti-Radiation Missile (HARM) test. HARM is designed to seek and destroy enemy air defense radars; it will be replaced by the AGM-88E AARGM beginning in 2010. Source.

July 31/08 – Aug 5/08: Initial sea trials on the USS Dwight D. Eisenhower [CVN-69] involve 319 approaches, 62 catapult shots and 62 arrested landings. They had originally been scheduled over 10 days, but that time was cut in half. VX-23 Sqn’s EA-18G department head, Cmdr. Jaime Engdahl describes some of their innovative responses in the NAVAIR release, and notes their combined use of developmental testers and operational testers in the cockpit at the same time. Engdahl:

“In OpEval, the operational testers already have hundreds of hours of flight testing, they know what the systems are like, they have input into design changes and potential problems. The real benefit is the Fleet gets a better product earlier.”

July 23/08: The EA-18G Test Team at NAWCWD China Lake conducts its first AIM-120 Advanced Medium Range Air-To-Air Missile (AMRAAM) live fire. While jamming threat systems located at Echo range, the Growler engaged and fired on the BQM-74E target drone. Airborne chase cameras as well as optical trackers on the target drone confirmed safe weapon separation, followed by a very close missile pass to the target drone. It was scored as a hit, since the AMRAAM warhead uses a proximity fuze.

This event marks the first release of any live weapons by an EA-18G. It also distinguishes the EA-18G by virtue of its air-air capability; other electronic warfare aircraft have traditionally relied on short range missiles like Sidewinders for self-protection. NAVAIR release.

June 24/08: Contract modification #0012 to a previously awarded contract (N00383-06-D-001J, order number 0004) for the purchase of initial spares in support of the E/A-18G Growler. Orders will be placed as needed, but this contract cannot exceed $45.7 million.

Work will be performed in St. Louis, MO, and will be complete July 2010. The Naval Inventory Control Point (NAVICP) in Philadelphia, PA manages the contract.

June 13/08: A $17.6 million modification to previously awarded firm-fixed-price contract N00019-04-C-0014 will incorporate engineering change Proposal 6251 and 6251R1. That proposal involves converting 18 of production Lot 32’s F/A-18F aircraft to EA-18G aircraft. Work will be performed in St. Louis, MO (70%), El Segundo, CA (29%), and Mesa, AZ (1%), and is expected to be complete in September 2010.

Boeing representatives confirm that this contract involves the routine process of converting basic F/A-18F production airframes into EA-18Gs, as part of the joint multi-year contract (Super Hornet MYP-II). This particular contract will install all of the required fittings et. al. that are necessary for the Growler’s specialized equipment. The actual contract for that equipment (wingtip pods, electronics “black boxes” et. al.) and its installation will follow later, as another modification.

June 3/08: Boeing delivers the first fleet EA-18G Growler airborne electronic attack (AEA) aircraft to the U.S. Navy’s VAQ-129 Vikings Electronic Attack Squadron at Naval Air Station Whidbey Island, WA ahead of schedule and within budget. The Vikings are a Fleet Readiness squadron, which means they’ll be the training squadron for all EA-18G pilots.

The delivery follows 5 test aircraft, and the Growler is scheduled to enter Operational Evaluation in September 2008. If OpEval goes well, the aircraft will be moved from Low-Rate Initial Production (LRIP) to full-rate production. Boeing release | US Navy.

May 14/08: Boeing holds a grand opening for its new EA-18G Growler Support Center (GSC) at Naval Air Station Whidbey Island, WA. The center will provide technical and logistics support for the EA-18s once the Navy accepts the first fleet Growler at the aircraft’s NAS Whidbey Island home base in early June of 2008.

The GSC will house approximately 24 representatives from the Navy and the Hornet/Growler industry team of Boeing, Northrop Grumman, Raytheon and General Electric. The center, along with the base’s existing supply chain management facility, will ensure that logistics support for new Growlers is readily available, per the FIRST performance-based maintenance contract for the US Navy’s Super Hornet fleet. Boeing release.

March 14/08: A $28.2 million modification to a previously awarded firm-fixed-price contract (N00019-07-C-0035) for time-critical parts in support of the EA-18G’s Low Rate Initial Production II (LRIP II) Airborne Electronic Attack kits.

Aug 22/07: $40 million for delivery order #0002 under previously awarded contract (N00383-06-D-001J), to purchase initial spares in support of the E/A-18 G Growler. Work will be performed at St. Louis, MO and is to be complete by May 2009. The Naval Inventory Control Point in Philadelphia, PA issued the contract.

August 6/07: A $10 million ceiling-priced modification to a previously awarded cost-plus-award-fee contract (N00019-04-C-0005) for the design, development, fabrication/assembly and qualification of up to 20 EA-18G Extended Low Band Radomes. Work will be performed in St. Louis, MO (55%) and Mesa, AZ (45%), and is expected to be complete in September 2009.

April 21/07 NAVAIR announces that the EA-18G Growler has finished an ambitious regimen of flight tests, concurrently completing both system developmental testing and an independent fleet operational assessment within the first 90 days of flight test. Feedback from operational testers is being immediately incorporated into development of the platform and its systems.

The EA-18G mission systems test team and aircrew from Flight Test and Evaluation Squadrons VX-23 at Pax River, VX-31 and VX-9 at NAWS China Lake, CA and Boeing contractor crews used EA-18G prototypes EA-1 and EA-2, logging over 100 hours of flight tests plus additional range testing as of late March 2007.

As one example of its success, the program schedule required the Growler to radiate ALQ-99 pods in a Pax River chamber by the end of February. As a result of early software delivery and solid system performance, the EA-18G test team was able to demonstrate this jamming capability in December 2006, radiate jammers in-flight by the end of January 2007, and ensure that jamming functions did not interfere with safe operation of any on-board systems across the entire ALQ-99 radiation spectrum. See full NAVAIR release: “Growler zaps through initial testing.”

Feb 16/07 A $6.5 million firm-fixed-price contract for time-critical parts in support of the EA-18G Low Rate Initial Production I Airborne Electronic Attack kits.

Work will be performed in Albuquerque, NM, and is expected to be complete in February 2008.

Feb 06/06: Boeing announces that the U.S. Navy has approved their test plans and processes for integrating several key subsystems into the EA-18G Growler. Successful completion of its first two test readiness reviews (TRR) in January 2005 and November 2005 allows Boeing to begin developing and integrating the systems at Boeing labs in St. Louis. The reviews focused on several key areas of the aircraft’s software: mission computer, electronic attack unit, the stores management system, interference blanking unit, the ALE-47 countermeasures system, EA-18G instrumentation system, mission planning and integration of the digital memory device.

Engineers will now focus on integration of EA-18G Build 1, the first of two builds of the airborne electronic attack aircraft software. The aircraft’s initial flight is scheduled for fall 2006 or early 2007, and EA-18G lab features like high-speed links and the Facility Automated Set-up and Test, or FAST architecture are designed to help engineers to meet the integration schedule. See Boeing release for further details.

Jan 31/06: A $19.7 million modification to a previously awarded cost-plus-award-fee contract (N00019-04-C-0005) for modeling and simulation, design, and development of a training system for the EA-18G aircraft. Work will be performed in Arlington, TX (50%) and St. Louis, MO (50%), and is expected to be completed in June 2008.

Jan 24/06: The EA-18G completes Jammer Flight Testing at Naval Air Warfare Center (NAWC), Patuxent River, MD. EA-18G department head (VX-23) Cmdr. Jaime W. Engdahl notes that the tests exercised all available jamming types for Build 1.5 in Bands 7/8/9, with “no notable EMC issues” and “no surprises.”

Naval Surface Warfare Center, Crane, IN is the cognizant Technical Authority for the plane’s AN/ALQ-99 Tactical Jamming System (TJS) Pod, and is teamed with Boeing, Northrop Grumman, and NAWC Point Mugu, CA to integrate the pod onto the EA-18G.

The word “pod” implies a level of plug-and-play that isn’t there; this effort required major electrical and structural modifications to the ALQ-99, including the development of the Pod Interface Unit, followed by 2 years of extensive environmental, flight performance, and integration testing performed at Crane, IN; Boeing in St. Louis, MO; and at NAWC Point Mugu and NAWC Patuxent River. US Navy.

Nov 8/05: Boeing completes the initial laboratory verification of the EA-18G tactical aircraft’s Interference Cancellation (INCANS) system, and demonstrates the system’s capabilities during aircraft ground testing at Naval Air Station Patuxent River, MD. The INCANS system will allow the EA-18G to conduct voice communications over UHF radio with friendly forces while simultaneously jamming enemy communications, a difficult trick. The current EA-6B Prowler, for example, can’t do this. See Boeing release.

Nov 15/01: Boeing Successfully Completes Initial EA-18 Flight Demonstration.

Appendix A: The EA-18G and the Future Force Mix

The question of exactly where and how the new Growlers will fit into the future force remains a live issue. There has been a serious absence of integrated direction and planning in the Pentagon over the last decade re: the future of airborne electronic warfare platforms, and a relatively low priority assigned to dedicated “Wild Weasel” (anti-SAM) or electronic attack capabilities. This has arguably taken place in an environment where current capabilities remained “good enough.” The result, however, may be a lack of a clear niche in terms of establishing the EA-18G’s mission breadth and concept of operations (CONOPS).

At the moment, the assumption must be that the EA-18G will do it all for the US military as a tactical strike jammer. Despite the existence of the turboprop-driven EC-130H Compass Call, wavering interest in EB-52 SOJ long-range bomber jammers for the USAF, and the potential to create USAF and US Marine electronic attack F-35 Lightning IIs and F-22A Raptors by leveraging their vast installed capabilities, the EA-18G Growler is currently slated to be the only dedicated aircraft in this niche.

While EA-18Gs will fit in very well with the USAF’s F-16s and F-15 Strike Eagles, and with their Super Hornet counterparts, operational challenges arise in pairing them with the stealthier F-35 Lightning II fighters slated for use by the USAF, Marines, and Navy; or with “Global Strike” teams of stealthy F-22As and B-2 bombers. Long-range aircraft like the B-52 or B-1 also present potential operational challenges, due to the EA-18G’s range.

As effective AWACS aerial surveillance aircraft and ever more sophisticated anti-aircraft missile systems being exported around the world, the answers to such challenges will matter. The Growlers aren’t scheduled to enter service until 2009, and the F-35 Lightning II may be delayed to 2015. The EA-18Gs will be invaluable during that 6 year interim and beyond, as a key accompaniment to the legacy force. By 2010, however, with the F-22 production line coasting to a close, Reagan-era aircraft beginning to retire, and a new set of partner aircraft and threat capabilities on the horizon, deeper thinking about the US military’s long-term airborne electronic attack capabilities and composition will be required.

The Growler squadrons will undoubtedly be necessary – but will they be enough?

Footnotes

(1) This doesn’t make the EA-6Bs the USA’s only electronic warfare aicraft. The US also has 13 “Compass Call” EC-130H Hercules variants, and these 4-engine turboprops offer long-endurance coverage that extends over very wide areas. Unlike an EA-6B or EA-18G, they won’t accompany strike packages directly. They do train to support tactical aircraft as they cross behind the forward edge of the battlespace (FEBA), while remaining behind the FEBA line themselves and blanketing a wide area with bogus primary targets, secondary targets, and targets of opportunity for enemy missiles and aircraft. They are also very well suited to providing persistent coverage for key convoys and other missions in-theater during “small wars” campaigns, and monitoring cell phone frequencies over wide areas.

The pending growth in stealthy and/or supercruising opposing fighters, coupled with longer-range air-to-air and ground-launched anti-aircraft missiles, is going to push FEBAs back sharply during state-to-state conflicts. That’s likely to magnify the strategic EW fleet’s role, in order to provide a protective cloak of misdirection that lets key strategic assets like aerial tankers and AWACS planes remain close enough to support allied fighters. The future strategic EW fleet will involve a tension between follow-on EC-130Js or similar aircraft to replace the EC-130H fleet, vs. a more distributed capability based on the USA’s Next-Generation Jammer, or similar pods that might equip most strategic assets sent near harm’s way.

Additional Readings and Sources

A quick note to readers. The aircraft’s official program name is the EA-18G Growler. On carrier decks, however, it’s called a “Grizzly,” just as its F/A-18F counterpart is a “Rhino” rather than a Super Hornet. This makes it impossible to confuse similar sounding names, amidst the thunderous cacophony of a carrier deck.
