KC-46A Pegasus Aerial Tanker Completes Firsts

DID’s FOCUS articles cover major weapons acquisition programs – and no program is more important to the USAF than its aerial tanker fleet renewal. In January 2007, the big question was whether there would be a competition for the USA’s KC-X proposal, covering 175 production aircraft and 4 test platforms. The total cost is now estimated at $52 billion, but America’s aerial tanker fleet demands new planes to replace its KC-135s, whose most recent new delivery was in 1965. Otherwise, unpredictable age or fatigue issues, like the ones that grounded its F-15A-D fighters in 2008, could ground its aerial tankers – and with them, a substantial slice of the USA’s total airpower.

KC-Y and KC-Z buys are supposed to follow in subsequent decades, in order to replace 530 (195 active; ANG 251; Reserve 84) active tankers, as well as the USAF’s 59 heavy KC-10 tankers that were delivered from 1979-1987. Then again, fiscal and demographic realities may mean that the 179 plane KC-X buy is “it” for the USAF. Either way, the KC-X stakes were huge for all concerned.

In the end, it was Team Boeing’s KC-767 NexGen/ KC-46A (767 derivative) vs. EADS North America’s KC-45A (Airbus KC-30/A330-200 derivative), both within the Pentagon and in the halls of Congress. The financial and employment stakes guaranteed a huge political fight no matter which side won. After Airbus won in 2008, that fight ended up sinking and restarting the entire program. Three years later, Boeing won the recompete. Now, they have to deliver their KC-46A.

Missile Envy: Modernizing the US ICBM Force

For 50 years, land-based Intercontinental Ballistic Missiles (ICBMs) have been part of the US primary strategic deterrence capability, the nuclear-armed triad that also includes submarine-launched ballistic missiles and long range heavy bombers.

Although the main target for the US deterrent – the Soviet Union – imploded in 1991, other threats – such as nuclear-armed rogue states and non-state actors – have emerged. To address these new threats, the US Air Force undertook a major ICBM modernization program.

To carry out this program, the USAF awarded a 15-year ICBM Prime Integration Contract (F42610-98-C-0001) in 1997 to a team led by Northrop Grumman. Since then, the team, which includes Lockheed Martin, Boeing, and ATK, has been carrying out a major modernization of the ICBM system to ensure its readiness.

Sons of Sa’ar? Israel’s Next Generation Frigates

The 1,227t/ 1,350 ton Sa’ar 5 Eilat Class corvettes were built by Northrop Grumman in the 1990s for about $260 million each. It’s a decent performer in a number of roles, from air defense to anti-submarine work, to coastal patrol and special forces support. In 2006, the Israelis went looking for a next-generation vessel with better high-end capabilities. Six years later, Israel had nothing to show for its search. In the meantime, massive natural gas deposits have been discovered within Israel’s coastal waters, adding considerable urgency to their search.

The USA is Israel’s logical supplier, but given Israel’s size and cost requirements, the only American option was the Littoral Combat Ship. Israel pursued that option for several years, conducting studies and trying to get a better sense of feasibility and costs. Their approach would have been very different from the American Freedom Class LCS, removing the swappable “mission modules” and replacing them with a fixed and fully capable set of air defense, anti-ship, and anti-submarine weapons. In the end, however, the project was deemed to be unaffordable. Instead, Israel began negotiating with Germany, and reports now include discussions involving both South Korea, and a local shipyard.

Global F/A-18 Hornet Fleets: Keeping ‘Em Flying

The F/A-18 Hornet is the F/A-18 E/F Super Hornet‘s predecessor, with the first models introduced in the late 1970s as a spinoff of the USAF’s YF-17 lightweight fighter competitor. Hornets are currently flown by the US Marine Corps as their front-line fighter, by the US Navy as a second-tier fighter behind its larger F/A-18 E/F Super Hornets, and by 7 international customers: Australia, Canada, Finland, Kuwait, Malaysia, Spain, and Switzerland. The USA’s aircraft were expected to have a service life of 20 years, but that was based on 100 carrier landings per year. The US Navy and Marines have been rather busy during the Hornets’ service life, and so the planes are wearing out faster.

This is forcing the USA to take a number of steps in order to keep their Hornets airworthy: replacing center barrel sections, re-opening production lines, and more. Some of these efforts will also be offered to allied air forces, who have their own refurbishment and upgrade programs.

Sikorsky’s $8.5-11.7B “Multi-Year 8” H-60 Helicopter Contract

In July 2012, the US military signed another huge contract with Sikorsky. With production of the Army’s HH/UH-60M, and the Navy’s MH-60S and MH-60R helicopters, all in full swing, there’s no question about the need for future orders. In that environment, multi-year contracts allow efficiencies in purchasing, and security of staffing, throughout Sikorsky’s supply chain. These new helicopter types are also available to Foreign Military Sales class customers, under the American contract’s advantageous pricing and terms. The UH-60M, MH-60S and MH-60R models have already inked export deals, and official requests indicate that more deals are in the pipeline.

The new multi-year 2013-2017 contract could be worth up to $11.7 billion, and follows a 5-year, multi-service “MYP-VII” contract in December 2007. Like its predecessor, it covers UH-60M Black Hawk troop transport and light cargo helicopters, Army HH-60M SAR (Search And Rescue) / MEDEVAC (MEDical EVACuation) helicopters, and the US Navy’s MH-60S and MH-60R Seahawk helicopters.

V-22 Osprey: The Multi-Year Buys, 2008-2017

In March 2008, the Bell Boeing Joint Project Office in Amarillo, TX received a $10.4 billion modification that converted the previous N00019-07-C-0001 advance acquisition contract to a fixed-price-incentive-fee, multi-year contract. The new contract rose to $10.92 billion, and was used to buy 143 MV-22 (for USMC) and 31 CV-22 (Air Force Special Operations) Osprey aircraft, plus associated manufacturing tooling to move the aircraft into full production. A follow-on MYP-II contract covered another 99 Ospreys (92 MV-22, 7 CV-22) for $6.524 billion. Totals: $17.444 billion for 235 MV-22s and 38 CV-22s, an average of $63.9 million each.

The V-22 tilt-rotor program has been beset by controversy throughout its 20-year development period. Despite these issues, and the emergence of competitive but more conventional compound helicopter technologies like Piasecki’s X-49 Speedhawk and Sikorsky’s X2, the V-22 program continues to move forward. This DID Spotlight article looks at the V-22’s multi-year purchase contract from 2008-12 and 2013-2017, plus associated contracts for key V-22 systems, program developments, and research sources.

Aging Aircraft: USAF F-15 Fleet Sees Renewed Interest

“Array of Aging American Aircraft Attracting Attention” discusses the issues that accompany an air force whose fighters have an average age of over 23.5 years – vs. an average of 8.5 years in 1967. One of the most obvious consequences is the potential for fleet groundings due to unforseen structural issues caused by time and fatigue. That very fear is responsible for the #1 priority placed on bringing new KC-X aerial tankers into the fleet to complement the USA’s 1960s-era KC-135 Stratotankers.

It can also affect the fighter fleet more directly.

Following the crash of a Missouri Air National Guard F-15C aircraft Nov 2/07 (see crash simulation), the US Air Force suspended non-mission critical F-15 flight operations on Nov 3/07. While the cause of that accident is still under investigation, preliminary findings indicate that a structural failure during flight may have been responsible. In response, Japan suspended its own F-15 flights, which left them in a bit of a bind – even as Israel’s F-15s joined them on the tarmac. As the effects continue to spread and the USAF and others continue to comment on this situation, DID continues to expand its coverage of this bellwether event. A conditional restoration of the American F-15A-D fleet to flight status was soon overturned by the re-grounding of that fleet as a result of the report’s conclusions – a status that remains only been partially lifted. Meanwhile, the accident report has been released (compete with video dramatization) and the status of the remaining aircraft will have significant implications for the USAF’s future F-15 fleet size. Not to mention its other procurement programs.

Then, too, this is America. Now there’s a lawsuit.

American AH-64D Apache: War Replacement Contracts

War takes its toll on equipment, as well as men. In some cases, it wears out. In other cases, enemy fire or accidents destroy equipment. The USA has recognized this fact by funding wartime replacement expenditures as supplemental funding, which is outside the normal budgetary process. The intent is that this money will be spent on replacing equipment that has been worn out, damaged or destroyed, or will be used to provide specialized capabilities like MRAP mine-resistant vehicles that are directly related to front-line demands.

Admittedly, this hasn’t always been true. Politicians are what they are, and so are large organizations like the military. One area where this ethic has undoubtedly been honored, however, has been the AH-64 Apache attack helicopter fleet. This article covers US Army Wartime Replacement Aircraft (WRA) AH-64D Longbow buys, which are the only truly new attack helicopters in the America’s inventory. That will change with the new Block III model, which is more advanced than the WRAs.

Raytheon’s APG-79 AESA Radars

The AN/APG-79 Active Electronically Scanned Array (AESA) radar began life as a replacement. Initial F/A-18 E/F Super Hornet production batches installed Raytheon’s all-weather, multimode AN/APG-73, but the APG-79 has intrinsic technical features that offered revolutionary increases in capability, reliability, image resolution, and range.

Unlike the APG-73 that equipped the first Super Hornets, the APG-79’s AESA array is composed of numerous solid-state transmit and receive modules that are fixed in place, eliminating a common cause of breakdowns. To move their beams, they rely on electronic changes in each module’s transmissions, creating useful interference patterns in order to aim, focus and shape their output. Other system components include an advanced receiver/exciter, ruggedized commercial-off-the-shelf (COTS) processor, and power supplies. With its open systems architecture and compact COTS parts, it changes what both aircrews and maintenance staff can do with a fighter radar – and does so in a smaller, lighter package.

The USA’s NGJ Strike Jammers: Raytheon’s Mid-Band Win

The US Navy owns the only operational tactical jamming fighters in the world, but the AN/ALQ-99 pods they depend on use analog technologies, are hard to maintain, and have reliability issues. All-digital technologies and modern transmit/receive electronics offer huge leaps ahead in capability and availability, which is why the US military is working on a Next-Generation Jammer (NGJ) replacement for the pods on its tactical strike aircraft.

The EA-18G Growler will be the NGJ’s first platform, but the flexibility of modern technologies mean that it may not be the last.
