“Completing the B61-12 on schedule is the latest example of what we’ve been saying for several years now: NNSA is delivering capabilities at the pace and scale needed by our Department of Defense partners and our deterrence requirements,” in a statement released Tuesday, January 7.
This success also sent a powerful signal to allies, adversaries, and stakeholders in Congress about America’s ability to maintain its nuclear deterrence capabilities.
Future Roles and Transition to the B61-13
The completion of the B61-12 program is not an endpoint but a stepping stone.
The B61-12 has already been certified for deployment on a wide range of aircraft, including the F-15E, F-35A, B-2 bomber, and German PA-200 Tornado.
Certification is underway for the US Air Force’s next-generation B-21 Raider and Italy’s Tornado fleet.
These certifications ensure the B61-12’s relevance across current and future platforms, solidifying its role in the US and NATO deterrence strategy.
As production of the B61-12 concludes, the NNSA is shifting its focus to the B61-13, a next-generation bomb announced in October 2023.
The B61-13 will feature a significantly higher yield of up to 360 kilotons, compared to the B61-12’s 50-kiloton maximum.
Slated for first production in fiscal year 2026, the B61-13 will leverage the production capabilities established during the B61-12 program, ensuring a seamless transition and maintaining momentum in the warhead modernization effort.

Implications for the US Nuclear Arsenal
The successful completion of the B61-12 LEP reflects the NNSA’s broader mission to modernize the US nuclear stockpile.
With six additional warhead modernization programs in the pipeline, the NNSA is investing heavily in updating its manufacturing infrastructure and capabilities.
These efforts aim to create a more resilient nuclear enterprise capable of meeting evolving deterrence objectives in an increasingly complex global security environment.
Dr. Marvin Adams, Deputy Administrator for Defense Programs, emphasized the broader significance of these achievements:
“Completion of the last B61-12 testifies to the successful collaboration we’ve had with our US Air Force and Department of Defense partners. The momentum built through B61-12 production and delivery will continue into delivery on the other six active weapons modernization programs and on additional programs that will become active in the coming years.”
Final Thoughts: A Strategic Step Forward
The completion of the B61-12 program represents a critical advancement in the US nuclear deterrence strategy. By modernizing its nuclear arsenal while maintaining precision and minimizing collateral damage, the US demonstrates its commitment to a safe, secure, and effective deterrence posture.

As the NNSA transitions to the B61-13 and other modernization programs, it reinforces the message that America’s nuclear enterprise is prepared to meet both current and future challenges.
This milestone not only reflects technological and operational success but also serves as a strategic deterrent in a world where nuclear capabilities remain a pivotal element of national security.
With the B61-12’s legacy secured and the B61-13 on the horizon, the NNSA continues to ensure that the US nuclear arsenal remains a cornerstone of global stability.
