Fighters, tankers, transports and trainers covered through engines, upgrades, flying hours, availability rates and the contracts keeping them airborne.
Lockheed Martin's Legion Pod trades radar energy for heat signatures, and years of U.S. Air Force test data lay out exactly how that trade works — and where the public record runs out.

Pilot shortages are decided years earlier in training command, where trainer throughput, instructor depth, and syllabus length set the force's ceiling.
Commercial electronics die on two-to-five-year production cycles while airframes live 30 to 50 years, and the gap decides when fleets get rebuilt.
Every flying hour an air force logs is a withdrawal against a depot ledger, and the refill rate at overhaul shops caps how fast any fleet can fly.
Aircraft waiting for heavy maintenance still count on paper, and the gap between the inventory and the flying fleet is decided at the depot gate.
