Lockheed Martin F-35 flight test program shows progress in first quarter

Lockheed Martin F-35 Lightning II test jets made considerable flight test progress during the first quarter of 2011, conducting 199 test flights versus a plan of 142 flights. Additionally, the F-35B short takeoff/vertical landing (STOVL) variant logged six times more vertical landings in the first quarter than in all of 2010. The test program remained ahead of plan despite the grounding of various test fleet aircraft for 4-15 days during the period as officials investigated the cause of a dual generator/starter failure during a flight on March 9.The F-35 Lightning II is a 5th generation fighter, combining advanced stealth with fighter speed and agility, fully fused sensor information, network-enabled operations and advanced sustainment. Lockheed Martin is developing the F-35 with its principal industrial partners, Northrop Grumman and BAE Systems.
