Weapons Tester Cites Further F-35 Challenges Aug 23, 2016
BUG FIXED THAT CAUSED MIDFLIGHT COMPUTER REBOOT, NOW ONLY EVERY 9 HR
F-35 JPO has corrected a bug in a previous iteration of software—Block 3i required for Air Force initial operating capability (IOC)—that caused the jet’s systems to stall out in mid-flight and need to be rebooted. But Aviation Week reported in July that at Edwards AFB, California, the team in charge of testing each new increment of software is now seeing the same stability events and shutdown issues with the new 3F.
Where test pilots were seeing shutdown events every five flight hours, a new 3F build improved performance to a point where the team is only experiencing an issue once every 9 hr., according to DOT&E. But that performance is still much worse than it should be; the final builds of 3i and 2B, which supported the Marine Corps’ IOC in 2015, experienced inflight stability events every 25 hr., according to DOT&E. In addition, testers are continuing to see problems booting up the jet.

The Air Force expects to operationalize the F-35 Joint Strike Fighter’s latest “3F” software iteration by September or October of this year, a development which will integrate additional technology and equip the stealth aircraft with a wider range of weapons, service leaders said.There are more than 10 million individual lines of code in the JSF system.
Block 3F will increase the weapons delivery capacity of the JSF as well, giving it the ability to drop a Small Diameter Bomb, 500-pound JDAM (Joint Direct Attack Munition) and AIM-9X short-range air-to-air missile, service officials explained. The AIM-9X is an Air Force and Navy heat-seeking infrared missile.
