The U.S. Air Force is proposing the retirement of 13 KC-135s and 16 KC-10s in fiscal 2021, while the successor Boeing KC-46A Pegasus is not considered operationally viable.

The Navy admits its five-year budget projection is likely to change once the service’s integrated force structure assessment is released.

The service’s fiscal 2021 budget request once again attempts to defer Block II upgrades for conventional forces Chinooks, but includes money to upgrade special operations forces MH-47Gs.
