BF-4, the first F-35 strike fighter test aircraft carrying all of the sensors that combat-ready F-35s will host, made its maiden flight on Wednesday, Lockheed Martin announced. Eric Branyan, Lockheed’s F-35 deputy program manager, said the 55-minute flight from the company’s F-35 assembly facility in Fort Worth, Tex., initiated “a level of avionics capability that no fighter has ever achieved.” During the flight, F-35 Test Pilot David Nelson checked the operation of these systems, which include an active electronically scanned array radar, electro-optical targeting system, EO distributed aperture system, electronic warfare system, helmet-mounted display system, and integrated communication, navigation, and identification suite. BF-4, which is scheduled to fly to NAS Patuxent River, Md., for more expansive flight testing with the sensors, is a Marine Corps’s F-35B short-takeoff variant. The Air Force’s F-35A version will have these same sensors as will the Navy’s F-35C.
A provision in the fiscal 2025 defense policy bill will require the Defense Department to include the military occupational specialty of service members who die by suicide in its annual report on suicide deaths, though it remains to be seen how much data the department will actually disclose.
