The Department of Defense (DoD) has unveiled plans for the development of a new, highly potent nuclear bomb, known as the B61-13, pending approval and funding from Congress. This decision comes in response to the evolving global security landscape, as outlined in the 2022 Nuclear Posture Review, and is a collaborative effort between the Department of Defense and the Department of Energy’s National Nuclear Security Administration (NNSA).
The B61-13, which is set to replace some B61-7s in the existing arsenal, will have a yield similar to the B61-7 but with enhanced safety, security, and accuracy features akin to the B61-12. This bomb will be deployable from aircraft, including the B-21 Raider stealth bomber currently under development, with a price tag of $692 million.
The primary aim of this development is to bolster the United States’ strategic capabilities and provide the President with increased flexibility in addressing larger and more resilient military targets. It is seen as a response to the shifting security environment, where U.S. competitors are modernizing their nuclear forces and expanding their reliance on nuclear weapons.
Importantly, the B61-13’s introduction will not increase the overall number of weapons in the U.S. stockpile, as the production of B61-12s will be reduced by a corresponding amount. This approach aligns with the Nuclear Posture Review’s strategy, emphasizing deterrence while pursuing arms control and risk reduction measures.
The Pentagon’s motivation for the B61-13’s development is rooted in the need to adapt to an ever-changing world and ensure the nation’s strength and security. Notably, the statement does not mention any specific countries like China or Russia in relation to this new weapon.
In sum, the B61-13 represents a balanced approach to address a dynamic security landscape and provides additional options for the U.S. to deter potential adversaries from challenging the nation’s security while also working towards arms control and risk reduction.
