The U.S. Air Force’s F-22 Raptor fleet remains grounded into a fourth month as the Air Force Scientific Advisory Board conducts a study of the F-22 and other aircraft using onboard oxygen generation systems (Obogs).
In another wide-ranging speech on future defense strategy, U.S. Secretary of Defense Robert Gates said that the U.S. Air Force must increase its focus on asymmetric threats and unconventional warfare.
Pratt & Whitney has delivered the first F135 production-standard short takeoff/vertical landing (STOVL) engine to Lockheed Martin for the F-35B Joint Strike Fighter program. The engine manufacturer plans to deliver another 18 STOVL engines next year. Any further design changes will likely be limited to “mostly software tweaks,” a P&W representative told AIN. Meanwhile, the U.S.
Raytheon is currently involved in two major upgrade programs for the U.S. Air Force’s Eagle fleet, providing AESA (active electronically scanned array) radars for both the air defense F-15C/D and the multi-role F-15E. Both programs have recently achieved significant milestones.
Japan is examining the possibility of continuing production of the Mitsubishi F-2 to bolster its fighter fleet in the face of growing Chinese capability, adding some 20 aircraft to the 94 (plus four prototypes) currently procured. The Japan Air Self Defense Force (JASDF) is looking for a new fighter and has stated a desire for the Lockheed Martin F-22 Raptor, but U.S. export restrictions have ruled that out.
Sukhoi has completed its preliminary flight and bench trials program for the T-50 PAK-FA fighter. Three airframes were built for the initial campaign, comprising one static aircraft (T-50-0), one flying prototype (T-50-1) and an avionics testbed (T-50-2). A display flight by T-50-1 on June 17 in front of Russian Prime Minister Vladimir Putin marked the 16th time the aircraft had flown.
After a bad start to 2010, U.S. officials are at Farnborough to persuade their eight international partners that the original ambitions for the F-35 Joint Strike Fighter are still intact. Escalating cost estimates and flight-test delays have cast a shadow over the airplane billed by Lockheed Martin as the only exportable fifth-generation fighter.
Northrop’s venerable T-38 Talon supersonic trainer entered service with the U.S. Air Force in March 1961 and has provided the advanced portion of the service’s training syllabus ever since. Over 1,100 were delivered and more than 450 remain in service.
In the interest of diversifying its fuel supply, the U.S. Air Force has been testing and certifying engines to run on a mixture of conventional jet fuel and biofuels derived from plants. Last month, testing began on a GE F110 using a 50/50 blend of the two fuels at the Arnold Engineering Development Center at AFB in Tennessee.
Northrop Grumman and Raytheon are going head-to-head with active electronically scanned array (AESA) radar programs to update F-16 fighters and other fighters around the world. Northrop Grumman announced yesterday that it now has U.S. State Department licenses to talk to a number of export customers at DSP-5 level, a status that Raytheon announced for its proposals in November.
