U.S. Navy to Build Hypersonic Weapon Facility at NWS Yorktown for Zumwalt and Virginia Classes

The US Navy plans a dedicated Conventional Prompt Strike weapons storage facility at Naval Weapons Station Yorktown to support Zumwalt-class destroyers and Block V and VI Virginia-class submarines. NAVFAC requirements specify a two-bay, earth-covered magazine with a 25-ton overhead bridge crane in each bay, plus mechanical buildings and emergency power infrastructure. Reinforced concrete construction, climate control and ordnance protection systems will accommodate the hypersonic rounds' size and handling requirements. The project provides Atlantic support infrastructure as ship conversions and submarine construction proceed, with Zumwalt's first CPS firing now expected in 2027.
