The Department of Defense adopts a common designation system for all military aircraft. The new system is based on existing (and much simpler) Air Force designation methods. The designations for most Air Force aircraft are unchanged, but all Navy, Marine, and Coast Guard aircraft are redesignated, as the Navy’s practice of including a letter to designate manufacturers is eliminated.
The rate of building B-21 bombers would speed up if the fiscal 2026 defense budget passes. But it remains unclear how much capacity would be added, and whether the Air Force would simply build the bombers faster, or buy more.
