In October of 2017 General Dynamics NASSCO hosted a christening and naming ceremony for the Navy's newest Expeditionary Sea Base, the USNS Hershel "Woody" Williams (ESB 4).
The USNS Hershel "Woody" Williams is the Navy's second ESB ship. The 784-foot-long ship will serve as a flexible platform to support a variety of missions, including air mine countermeasures, counter-piracy operations, maritime security and humanitarian missions. The ship will provide for accommodations for up to 250 personnel, a 52,000-square-foot flight deck, fuel and equipment storage, and will also support MH-53 and MH-60 helicopters with an option to support MV-22 tilt-rotor aircraft.
On February 22, 2018 the Navy accepted delivery of its second Expeditionary Sea Base (ESB) ship, the USNS Hershel “Woody” Williams (ESB 4).
