“There has been talk for decades about a true successor to the specialized deep bunker-busting B61-11 nuclear bomb.”

The Department of Energy is seeking millions of dollars for work in part on a new bunker-busting nuclear weapon called the Nuclear Deterrent System-Air-delivered (NDS-A) in its latest budget request. At present, there is only one specialized air-delivered deep-penetrating weapon known to be in America’s nuclear stockpile, the B61-11 gravity bomb, and there have been discussions about a potential successor for decades now.
The Fiscal Year 2027 budget request for the Department of Energy, which was released last month, includes a new line under Weapons Activities for Future Programs. The Department is asking for $99.794 million in the next fiscal cycle to support those efforts.
