“The limited and incomplete F-35 cyber-security testing accomplished to date has … revealed deficiencies that cannot be ignored,” Michael Gilmore, the director of combat testing, said in a prepared statement for a hearing by the House Armed Services subcommittee on tactical air and land forces. Gilmore’s testimony summarises earlier reports that detail the risks of concurrent development and production of weapon systems.
Furthermore, the mission systems software supporting the aircraft’s Northrop Grumman AN/APG-81 AESA radar is not stable enough for combat, according to Gilmore’s testimony. The radar has to be restarted once every four hours of flying time, the statement said.
