Growler

The U.S. Navy released a draft request for proposals (RFP) last month for its future airborne electronic warfare system, the Next Generation Jammer (NGJ), signaling a shift in the $2 billion program to the technology development phase. Contained in under-wing pods on the Navy’s EA-18G Growler, the NGJ will suppress advanced, integrated air defenses, communications systems, datalinks and other threats, replacing the long-serving AN/ALQ-99 tactical jamming system on the Boeing EA-18G and retiring Northrop Grumman EA-6B Prowlers.

APKWS

After several years of testing, the U.S. Marine Corps has deployed the BAE Systems Advanced Precision Kill Weapon System (APKWS) to Afghanistan. The APKWS is a conversion of the Hydra 70-mm unguided rocket into a precision-guided munition through the addition of the WGU-59/B mid-body guidance unit developed by BAE.

Composite Technology, a Sikorsky Aerospace Services company based at Dallas/Fort Worth Airport, has opened a $15 million structure to dynamically balance helicopter main rotor blades. It can test main rotor blades that rotate either clockwise or counterclockwise, and its two 3,000-shp, variable-frequency drive motors make it suitable for light to heavy helicopters. A test involves three blades: a precision-balanced master blade and two test blades. One blade can weigh up to 500 pounds.

F-35A

Lockheed Martin has described progress in the F-35 development program, and solutions to some of the problems that have recently been identified. Having exceeded the planned flight-test sorties and test points in 2011 by 15 percent, the company is hoping for similar gains this year. Of the 59,585 test points scheduled for the development phase through 2016, just over one-fifth had been flown by the end of December.

Pratt & Whitney’s engines power a wide range of military aircraft in operation around the world, but 2011’s developments in the Joint Strike Fighter (JSF) Lightning II program made the company’s year–especially as its F135 became the sole powerplant for all three Lockheed Martin JSF variants: the conventional F-35A, STOVL F-35B and carrier-based (CV) F-35C.

S-97 Raider

Sikorsky Aircraft has named 35 suppliers participating in an industry-funded effort to build two prototype S-97 Raider helicopters for evaluation by the U.S. military.The Raider is a follow-on to the company’sX2 technology demonstratorwith coaxial contra-rotating main rotors and a pusher propeller.

Sikorsky said it will invest about 75 percent of the Raider program’s expected cost, with suppliers investing 25 percent. Last June, Sikorsky and General Electric signed an agreement under which GE Aviation will provide its CT7-8 engine for the Raider.

Sikorsky has selected GE Aviation (Booth No. 1217) to provide the GE YT706-GE-700R engines and engineering support for Sikorsky’s S-97 Raider program. The Raider is the military version of the experimental X2, a single-engine rotorcraft with coaxial counter-rotating main rotors and a pusher propeller. The Fadec-controlled GE engine offers 2,500 to 3,000 shp and is based on the GE700/CT7 family. GE said it developed the GE3000 for medium-lift applications and this engine could be incorporated into the Raider in the future.

F-35B delivery

There was good news for the F-35 program when U.S. Secretary of Defense Leon Panetta ended the two-year “probation” for the STOVL version a year early. Lockheed Martin F-35B executive v-p Larry Lawson said that “critical engineering challenges” had been solved.

F-35

The Lockheed Martin F-35 Joint Strike Fighter program faces fresh challenges as the new year begins. First, a long-awaited “should cost” review from the U.S. Defense Acquisition Board might clarify whether Lockheed Martin’s continued optimism on the average procurement unit costs (APUC) is justified. In addition, big cuts to the U.S. defense budget seem unlikely to spare the F-35, which is the Pentagon’s highest profile acquisition, and might undermine the basis for the APUC calculations.
