U.S. Air Force Enhances Bomber Fleet with B-21 Development and Upgrades to B-52, B-1B, and B-2
The U.S. Air Force operates three strategic bombers: the B-52, B-1B, and B-2, for conventional and nuclear missions. A new B-21 strategic bomber is under development to enhance stealth capabilities and support nuclear operations.
The 2022 Nuclear Posture Review affirmed bombers as a key part of the U.S. nuclear triad. The Air Force has begun Bomber Task Force deployments to reassure allies and deter adversaries. The B-52, capable of carrying 70,000 lbs of ordnance, is scheduled for life extension into the 2040s.
The B-1B can carry a payload of 75,000 lbs, with 45 currently in service. The B-2, a stealth bomber, has 20 units operational. The B-21 is expected to enter service in the mid-2020s with a projected cost of $550 million each. Congress is evaluating the bomber fleet size and potential need for 145 B-21s, as well as future upgrades and the implications of re-alerting bombers.
