F-35As at the Air Force’s first operational Lightning II base have started flying sorties in standard training formation to get ready for initial operational capability later this year. The jets, on May 2, began flying in routine four-ship combat training missions out of Hill AFB, Utah. Pilots from the 388th and 419th Fighter Wings are relying on the jet’s troubled software to fly close together, evade simulated threats, and destroy targets, according to a 419th FW release. While Hill jets first flew in this formation in March to test the ability, the May 2 flights marked the beginning of the routine training exercises. “We’ve vetted and tested our ability to generate four-ships and doing so regularly will become routine, which is a significant step on the road to initial operational capability,” said Capt. Richard Palz, the 34th Aircraft Maintenance Unit officer in charge, in the release. Hill will eventually house three F-35 squadrons, with 78 aircraft by the end of 2019. The Air Force expects to reach IOC by the end of this year. The program office recently fixed software glitches that have hindered test and training flights.
Depot-level maintenance took longer than expected for nearly three-quarters of Air Force aircraft from fiscal 2019-2024, according to a new report, as unplanned repairs rise across the aging fleet. The report, from the Government Accountability Office, also found that the extent of the delays has been masked because officials often revise their target timelines after unplanned work occurs.
