NASSCO starts construction of ESB 5

JANUARY 27, 2017 — General Dynamics NASSCO shipyard in San Diego this week began construction on a fifth ship for the U.S. Navy’s Expeditionary Transfer Dock (ESD)/Expeditionary Sea Base (ESB) program.

Designed to provide advanced flexibility and capability for sea-to-shore missions, the newest ESB will include a 52,000 square-foot flight deck, fuel and equipment storage, repair spaces, magazines, mission planning spaces and accommodations for up to 250 personnel. Serving as a “pier at sea,” the 784 ft ship is also designed to support MH-53 and MH-60 helicopters and MV-22 tilt rotor aircraft.

The ship, ESB 5, is the fifth to be added to a contract between the shipbuilder and the U.S. Navy that originally called for two Expeditionary Transfer Docks: USNS Montford Point (T-ESD 1) and USNS John Glenn (T-ESD 2).

The first two ships, formerly classified as Mobile Landing Platforms (MLPs), were designed and constructed by NASSCO to support vehicle staging and transfers, and the movement of LCAC vessels. In 2012, a third ship, USNS Lewis B. Puller (T-ESB 3), was added to the contract and reconfigured as an ESB, formerly known as a MLP Afloat Forward Staging Base, to support a wide range of military operations. All three ships have been delivered to the U.S. Navy, and in October 2015, NASSCO began construction on ESB 4, USNS Hershel “Woody” Williams.
