AGM-158 JASSM: Lockheed’s Family of Stealthy Cruise Missiles

The 2,000 pound AGM-158 JASSM (Joint Air-to-Surface Standoff Missile) is intended to be a stealthy, inexpensive GPS/IIR (Global Positioning system/ Imaging InfraRed) guided cruise missile. It’s designed to attack well-defended targets without putting its carrier aircraft in the crosshairs of new long-range surface to air missile systems. JASSM has experienced a rocky development history, due to long-standing reliability issues. In 2005 it was threatened with cancellation following a series of poor test results. The program went through 2007 on an ongoing roller coaster of ups and downs, and by May 2009 it appeared the program was facing cancellation once again.

A production hiatus did take place between Lot 7 and FY 2010’s Lot 8 in FY 2010, but test results allowed the USAF to move forward, and the missile is beginning to win export orders.

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.

Phalanx CIWS: The Last Defense, On Ship and Ashore

The radar-guided, rapid-firing MK 15 Phalanx Close-In Weapons System (CIWS, pron. “see-whiz”) can fire between 3,000-4,500 20mm cannon rounds per minute, either autonomously or under manual command, as a last-ditch defense against incoming missiles and other targets. Phalanx uses closed-loop spotting with advanced radar and computer technology to locate, identify and direct a stream of armor piercing projectiles toward the target. These capabilities have made the Phalanx CIWS a critical bolt-on sub-system for naval vessels around the world, and led to the C-RAM/Centurion, a land-based system designed to defend against incoming artillery and mortars.

This DID Spotlight article offers updated, in-depth coverage that describes ongoing deployment and research projects within the Phalanx family of weapons, the new land-based system’s new technologies and roles, and international contracts from FY 2005 onward. As of Feb 28/07, more than 895 Phalanx systems had been built and deployed in the navies of 22 nations.

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

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.

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.
