On April 3, Under Secretary of Defense for Policy John Rood told lawmakers that the Pentagon was developing a low-yield nuclear cruise missile for submarines. Rood said that the program was included in the Defense Department’s FY 2020 budget request, and is still in the early stages of development. “The sub-launched cruise missile is further behind [than the low-yield ballistic missile], and we’re just doing an AoA or analysis of alternatives at this stage,” Rood explained.
