The following statement is attributable to Mr. John Rood, Under Secretary of Defense for Policy.
The U.S. Navy has fielded the W76-2 low-yield submarine-launched ballistic missile (SLBM) warhead. In the 2018 Nuclear Posture Review, the department identified the requirement to “modify a small number of submarine-launched ballistic missile warheads” to address the conclusion that potential adversaries, like Russia, believe that employment of low-yield nuclear weapons will give them an advantage over the United States and its allies and partners. This supplemental capability strengthens deterrence and provides the United States a prompt, more survivable low-yield strategic weapon; supports our commitment to extended deterrence; and demonstrates to potential adversaries that there is no advantage to limited nuclear employment because the United States can credibly and decisively respond to any threat scenario.
