W88 Alteration 370 (Maintaining the Stockpile)
The W88 nuclear warhead entered the stockpile in late 1988 and is deployed on the Navy’s Trident II D5 Submarine-Launched Ballistic Missile (SLBM) system, carried onboard Ohio-class ballistic missile submarines. Deployed now for almost three decades, several updates are required to address aging issues and to maintain its current state of readiness. The W88 Alteration (Alt) 370 program replaces the arming, fuzing, and firing subsystem, adds a lightning arrestor connector, and refreshes the conventional high explosives within the weapon to enhance nuclear safety and support future life extension program options. The W88 Alt 370 program is scheduled to be completed concurrent with planned exchanges of limited-life, or routinely replaced, components, including the gas-transfer system
