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.

Sikorsky Aircraft 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’s X2 technology demonstrator with coaxial contra-rotating main rotors and a pusher propeller.

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.

The first international Joint Strike Fighter, an F-35B for the UK, was rolled out on November 22, one week before a parliamentary report shed more light on the UK’s decision to switch from the STOVL F-35B version to the conventional carrier landing F-35C version.

Critics may say that Boeing’s argument is self-serving, but McCrary and colleagues believe that the upgrades already made or pending on the F-15 and F-18 prove their point.

The U.S. Air Force will proceed with a service life extension program (SLEP) and avionics upgrade of 300 to 350 F-16 Fighting Falcons to compensate for an expected two-year slip in operational readiness of the F-35A Lightning II, service leaders told the U.S. Congress on November 2.

F-35 Joint Strike Fighter

The F-35 Joint Strike Fighter has gone to sea for the first time. An F-35B short-takeoff vertical landing (STOVL) version landed on the small U.S. aircraft carrier Wasp on October 3 at the start of a two-week trial during which 67 takeoffs and landings are scheduled. Some observers have raised concerns about the potential for damage to carrier decks from the aircraft’s F135 engine. It develops 39,400 pounds of thrust in the hover and 38,100 pounds of thrust in short takeoff.
