The U.S. Air Force is aiming to field a next‑generation airlifter to replace both the C‑17 and C‑5 as soon as 2038, but now expects the C‑17 fleet to remain in service and a complete transition not until 2075. The gap forces multi‑decade sustainment and acquisition planning.

Briefing
The USAF projects an earliest fielding of a next‑generation airlifter in 2038 while forecasting a full fleet transition only by 2075, meaning C‑17 and C‑5 operations will overlap with the new platform for decades.
That timeline locks in long‑term sustainment, industrial‑base and procurement implications; see how current C‑17 units sustain high readiness in the Pacific and the service's parallel push to extend legacy tanker production and timelines (including NGAS/KC‑46 discussions): https://hype.aero/?story=7888e5b9-6a01-4ff3-9924-366400058a93 and https://hype.aero/?story=35b9c4c2-db40-4483-843e-3d840249f4a0.
