—”“Mission capable” is a tricky term.”
YES! And zero details were provided.
“As of September 21, 2023, the average mission capable (MC) rate of the US Air Force’s F-35 fleet was 55%. This is below the targets of 90% for the F-35A and 85% for the F-35B and C variants. The MC rate is defined as when an aircraft is able to perform one of its tasks.
The Air Force and Navy F-35s have also exceeded the requirement for “Mean Flight Hours Between Maintenance Events (Unscheduled)” by 110% and 120%, respectively. However, the DOT&E has recommended more investment in spares, especially for F135 engines, to reduce downtime for aircraft waiting for spare parts.”
