Lockheed Martin Built F-35 Aircraft Achieves Flight Test Milestones

US: Lockheed Martin’s F-35 Lightning II aircraft has demonstrated air-to-air combat capability, completed the first flight test with the next level software load and accomplished a landing at the maximum test speed and drop rate. In the Point Mugu Sea Test Range airspace off the Central California coast, an F-35B demonstrated the jet’s air-to-air combat capability when it sequentially engaged two aerial targets with two AIM-120 Advanced Medium Range Air-to-Air missiles (AMRAAM) during a Weapon Delivery Accuracy mission.

“The US Marine Corps, which operates F-35Bs, will be the first military service branch to attain combat-ready Initial Operational Capability (IOC) in 2015. This Weapon Delivery Accuracy test highlighted the air combat capability that will give Marine aviators a decisive combat edge in contested airspace,” said J D McFarlan, Lockheed Martin's vice president for F-35 Test & Verification. The F-35’s internally-carried AIM-120 AMRAAMs are a beyond-visual-range air-to-air missile capable of all-weather day-and-night operations and considered a fire-and-forget missile using active target radar guidance. Flying from Edwards Air Force Base, an F-35A flew a 1.9 hour mission with the first-ever load of Block 3i hardware and software. Block 3i is the next level of capability and is planned to support US Air Force F-35A IOC in 2016. The F-35C, designed for aircraft carrier operations, completed a landing at its maximum sink speed to test the aircraft’s landing gear, airframe and arrestment system at Naval Air Station Patuxent River, Maryland. “Five sorties were conducted, building up the maximum sink rate test condition of 21.4 feet per second, which represents the maximum sink speed planned for this test,” added McFarlan. During the tests, the F-35C did three arrestments, several touch and goes and one bolter. The landings were to demonstrate structural readiness for arrested landings on an aircraft carrier at sea. Fleet-wide, the F-35 has, to date, amassed more than 17,000 flight hours, with all three variant aircraft at the F-35 Integrated Training Center at Eglin AFB, Florida, surpassing the 5,000 sorties milestone this week.
