USN Ship Protection: From “Slick 32s” to SEWIP

“Slick 32”

The US Navy’s AN/SLQ-32 ECM (Electronic Countermeasures) system uses radar warning receivers, and in some cases active jamming, as the part of ships’ self-defense system. The “Slick 32s” provides warning of incoming attacks, and is integrated with the ships’ defenses to trigger Rapid Blooming Offboard Chaff (RBOC) and other decoys, which can fire either semi-automatically or on manual direction from a ship’s ECM operators.

The “Slick 32” variants are based on modular building blocks, and each variant is suited to a different type of ship. Most of these systems were designed in the 1970s, however, and are based on 1960s-era technology. Unfortunately, the SLQ-32 was notable for its failure when the USS Stark was hit by Iraqi Exocet missiles in 1987. The systems have been modernized somewhat, but in an era that features more and more supersonic ship-killing missiles, with better radars and advanced electronics, SLQ-32’s fundamental electronic hardware architecture is inadequate. Hence the Surface Electronic Warfare Improvement Program (SEWIP).

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

EA-18G at Pax

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.

EA-6B Prowler

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.

Billions to Upgrade and Up-arm Pakistan’s F-16s

PAF F-16A drops Mk.82s

On June 28/06, the US DSCA notified Congress via a series of releases of its intention to provide Pakistan with a $5.1 billion Foreign Military Sales package to upgrade the F-16s that serve as the PAF’s top of the line fighters. Some of these items had been put on hold following the October 2005 earthquake in Pakistan & Kashmir, but the request for 36 new F-16 Block 50/52s is now going ahead, along with new weapons, engine modifications, and upgrade kits for Pakistan’s older F-16 A/Bs. The buy went through, and was accompanied by the supply of 26 older F-16s from USAF surplus stocks. Then, a 2014 sale added 13 machines from from Jordan.

These items are detailed below, along with controversies the proposed sales have created, and some of the conditions attached to the sale by the US government….

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

EA-18G Growler

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.

Israel Announces F-16 Variant Upgrades

F-15s: Note Kill Stickers

F-15s and F-16s make up the backbone of Israel’s potent fighter force. The IDF’s main fighter is the F-16 Fighting Falcon, including aging F-16 A/B Netz (“Falcon”), plus F-16C Barak (“Lightning”) and 2-seat F-16D Brakeets (“Thunderbolt”), and now the heavily customized two-seat F-16I Block 52+ Soufa (“Storm”). The Israelis fly the largest contingent of F-16s outside the United States, alongside longer range, higher performance F-15s. F-15A-D Baz (“Eagle”) models have greatly distinguished themselves in IDF service, and the customized two-seat F-15I Ra’ahm (“Thunder”) Strike Eagle is optimized for advanced ground attack and long range interception. All of these aircraft are heavily modified from the US versions, with Israeli avionics, self-protection systems, weapons, and sometimes radars as well.

While Israel’s F-16A/B Netz inventory may well be sold on the international market, their F-16 C/D and F-15 A-D planes were expected to serve the Air Force Corps until at least 2020. Unfortunately, Israel’s new F-35As won’t even start arriving until 2016 or 2017. To keep their edge, Israel began spending money in 2006 to improve and upgrade its legacy fighter fleet…

Australia’s 2nd Fighter Fleet: Super Hornets & Growlers

RAAF F/A-18F rollout

Australia’s A$ 10+ billion Super Hornet program began life in a storm. Australia’s involvement in the F-35 Lightning II program have been mired in controversy, amid criticisms that the F-35A will (1) be unable to compete with proliferating SU-30 family fighters in the region, (2) lack the range or response time that Australia requires, and (3) be both late and very expensive during early production years.

The accelerated retirement of Australia’s 22 long-range F-111s in 2010 sharpened the timing debate, by creating a serious gap between the F-111’s retirement and the F-35’s likely arrival. Further delays to the F-35 program have created new worries that even the upgraded F/A-18AM/BM Hornet fleet won’t last long enough to allow smooth replacement.

The Super Hornets survived potential cancellation, and the “surprise” stopgap buy has steadily morphed into a mainstay of the future RAAF, with a new and unique set of electronic warfare capabilities thrown into the mix. This DID Spotlight article describes the models chosen, links to coverage of the key controversies, and offers a history of contracts and key events from the program’s first official requests to the present day.

$96M to DS2 for LAIRCM Aircraft Defense System Support

LAIRCM Concept

Defense Support Services (DS2), a Greenville, SC-based venture between Lockheed Martin and Day & Zimmermann, received a $96 million contract to provide support for the Large Aircraft Infrared Countermeasure (LAIRCM) System.

Northrop Grumman’s LAIRCM is a laser-based countermeasures system that is designed to defend C-17 and C-130 transport aircraft and other large, slow-moving aircraft from an infrared missile attack by automatically detecting a missile launch, determining if it is a threat, and activating a high-intensity system of pulsed lasers to track and defeat the threat by confusing its guidance head…

Israel’s AH-64A Attack Helos Get Custom Upgrades – Despite the USA

Israeli AH-64D

Israel’s attack helicopter fleet still flies AH-1 Cobras, but larger and more heavily armored AH-64 Apache helicopters began arriving in 1990, and have distinguished themselves in a number of war since. The country received 44 AH-64A helicopters from 1990 – 1993. Additional buys, conversions, and losses placed the fleet at 45 helicopters as of Flight Global’s World Air Forces 2013 report, split between AH-64As and more modern AH-64D Longbows.

The AH-64D Longbow’s sophisticated mast-mounted radar can quickly pick up tanks and other dangerous targets, but isn’t designed to distinguish civilians from combatants, or to hover close over the deck in highly populated areas. Confronted by asymmetrical urban warfare and budget priority issues, and faced with a lack of cooperation from the Obama administration, the IAF decided in 2010 to forego AH-64D upgrades for their remaining helicopters. On the other hand, the type’s consistent usefulness has led Israeli to make extensive improvements of their own, to the point where Israel has effectively created their own improved AH-64A configuration…

Armed & Versatile: Sikorsky’s ‘Battlehawk’ Helicopters

AH-60L

The UH-60M Black Hawk is currently the most advanced UH-60/S-70 model, whose variants are in service with the US Army and over 20 other countries around the world. To date, UH-60M customers include the USA, Bahrain, and the United Arab Emirates, plus a request from Egypt. Unlike global competitors such as Russia’s Mi-8/17 series, however, the UH-60’s operational armament is generally limited to door guns. That may be about to change, thanks to a UAE initiative.

Colombia currently flies the armed S-70 “Arpia III”, and Sikorsky has worked on armed “AH-60” versions as an offering in some foreign competitions, but efforts to sell the concept in Australia and elsewhere were less successful. Nevertheless, Sikorsky executives see considerable potential for multi-role helicopters and conversion kits, in an era of global insurgencies, tight budgets, and limited helicopter numbers. Now, the UAE has become their launch customer. What is Sikorsky’s Battlehawk, and what are their plans?

Expendable Wave: Raytheon’s MALD & MALD-J Decoys

ADM-160B/C MALD

The Bosnian “Nighthawk Down” incident in 1999 showed that even old air defense systems could still be dangerous, and that smart tactics and selective use could keep those systems alive against heavy opposition. The challenge is finding them and targeting them. Against truly advanced air defense systems like the Russian SA-20 family, however, the challenge is survival. Advanced stealth technologies, advanced anti-radar weapons, and successful electronic jamming are required.

Air-launched decoys can help, and they are not a new concept by any means. The same technologies used in cruise missiles allow construction of “stealth in reverse” decoys that fly long distances along pre-planned flight patterns, carrying radar reflectors that simulate the radar return of fighter or bomber aircraft. Enemy air defenses see them as incoming aircraft, and must decide to either shut down and hide, or activate and reveal their position. If American aircraft are flying behind a wave a decoys, either option can be dangerous. The USAF’s ADM-160B/C Miniature Air-Launched Decoy (MALD) program began as a DARPA effort in 1996, but made it all the way into production, and is branching out into new fields. The US Navy already has their own ITALD, but they liked one of the new MALD variants enough to add it, too.
