The US Marine Corps' (USMC) Marine Fighter Attack Squadron (VMFA) 211 has resumed flight operations of the F-35B Lightning II short take-off / vertical landing (STOVL) variant, following a temporary suspension period due to software issues.
VMFA 211 is an F-35B squadron with 3rd Marine Aircraft Wing based at Marine Corps Air Station (MCAS) Yuma, Arizona, which is the first operational F-35B base.
The decision to temporarily suspend VMFA-211 flight operations was made by the 3rd Marine Aircraft Wing commanding general major general Mark Wise.
The suspension was related to pending fixes to a recent autonomic logistics information system (ALIS) software upgrade within version 2.0.2 that had shown certain anomalies.
USMC said in a statement that the issues associated with the ALIS software update were mitigated at MCAS Yuma.
The F-35 Joint Programme Office (JPO) identified the root cause of the issues and generated the software fix to resolve them, in collaboration with the action team from Lockheed Martin.
Lockheed Martin and the JPO will now continue to jointly monitor and enhance the performance of the ALIS software, which is the management support system for the F-35 Lightning II joint strike fighter.
The F-35B STOVL variant is slated to eventually replace the AV-8B Harrier, the F/A-18 Hornet, and the EA-6B Prowler platforms.
USMC’s F-35B aircraft reached initial operational capability on 31 July 2015.
