AFGSC Commander Reveals Inside Story on B-21 Raider, B-52J Upgrades, Sentinel ICBM, and AI’s Role in Nuclear Deterrence
Gen. Bussiere outlined modernization of the B-52J, B-21 Raider, and ICBMs, emphasizing bomber readiness and AI’s supportive role in nuclear command and control. The Sentinel missile marks a key upgrade in deterrence capabilities.
AFGSC Commander Discusses B-21 Raider, B-52J, ICBMs, and AI in Nuclear Command
Gen. Thomas A. Bussiere, Commander of Air Force Global Strike Command (AFGSC), recently shared key insights on U.S. bomber modernization, strategic deterrence, and the evolution of nuclear command and control. Charged with managing two of the three legs of the U.S. nuclear triad, Gen. Bussiere reflected on his 40-year career and outlined the critical modernization efforts sustaining a credible deterrent amid a challenging global security environment.
Operational Tempo of Bomber Forces in 2024
In 2024, AFGSC executed 33 Bomber Task Force (BTF) missions across multiple theaters, including Europe, Indo-Pacific, Central Command, NORTHCOM, SOUTHCOM, and AFRICOM. These missions combined presence, engagement, and training with allied forces, emphasizing integration and interoperability.
Additionally, the Immediate Response Force (IRF) was activated five times last year, with three no-notice combat deployments involving all three bomber types: B-1, B-2, and B-52. Gen. Bussiere stressed the constant readiness required of bomber and ICBM crews alike, maintaining a force posture that has remained on alert since 1962.
The B-52J Upgrade
Marking over seven decades since its first flight, the B-52 continues to evolve. The B-52J will feature new Rolls-Royce F130 engines, enhancing fuel efficiency, range, and maintenance costs. This upgrade replaces the 1960s-era Pratt & Whitney engines and extends the bomber’s service life through at least 2050.
The aircraft will also receive a modernized APG-79 AESA radar, improving detection capabilities while freeing up space for future electronic warfare systems. Notable external changes include removal of the AN/ASQ-151 Electro-Optical Viewing System blisters, as newer targeting pods now fulfill low-level flight support.
Inside, the cockpit will be enhanced with multifunction digital displays and a hybrid mechanical-digital throttle, though some analog instruments will remain. The crew size will reduce from five to four, simplifying operations without sacrificing capability. These changes ensure the B-52J remains a reliable long-range strike platform alongside the new B-21 Raider.
The B-21 Raider: A New Era in Bomber Capability
Described as the most advanced bomber ever built, the B-21 Raider is undergoing developmental testing at Edwards Air Force Base. It will eventually replace both the B-1 and B-2 bombers, operating alongside the B-52J to balance innovation with proven endurance.
MH-139 Grey Wolf Helicopter Deployment
The MH-139 Grey Wolf, based on the AW139, is replacing Vietnam-era UH-1N Hueys at missile wings. This helicopter offers significant improvements in range, speed, payload, and survivability, providing enhanced security for intercontinental ballistic missile (ICBM) fields and convoys.
Modernizing the ICBM Force: Sentinel and Beyond
The Minuteman III ICBM, in service for 55 years, remains a credible deterrent thanks to dedicated Airmen. However, the Sentinel weapon system is set to replace it as the first new operational ICBM in decades.
The LGM-35 Sentinel missile will be larger but lighter than its predecessor, benefiting from modern materials and manufacturing. It will carry a single W87 Mod 1 warhead with a variable yield up to 475 kilotons, and can accommodate decoys to counter missile defenses. The first plutonium pit for this warhead was produced in October 2024—the first since 1989—signaling progress in nuclear modernization.
Artificial Intelligence in Nuclear Deterrence
Gen. Bussiere highlighted the growing role of artificial intelligence (AI) in supporting the deterrence mission, especially in processing vast intelligence data and enhancing nuclear command, control, and communications (NC3). AI offers potential to quickly analyze complex data sets and improve communication pathways across space, air, ground, and cyber domains.
However, AI will not replace human decision-making in nuclear operations due to the mission's critical nature. Senior leaders remain cautious about direct AI involvement in such decisions, though AI applications in supporting roles are expanding.
