Aviation covers military aircraft across their service life: acquisition, upgrade blocks, engine performance, flying hours, availability rates and sustainment cost. Reporting draws on audit reports, fleet statistics and operator statements. Intended for aircrew, maintenance planners, procurement staff and analysts comparing what fleets can generate on a given day.
Fighters, tankers, transports and trainers covered through engines, upgrades, flying hours, availability rates and the contracts keeping them airborne.
Mission capable rates sound like a single honest number, but the metric hides split counts, partial missions, and depot queues that explain most of the gap.
