The U.S. Navy accepted delivery of its ninth Expeditionary Fast Transport (EPF) vessel, USNS City of Bismarck (EPF-9), December 19.
EPFs are shallow draft, all aluminum, commercial-based catamarans that are capable of intra-theater personnel and cargo transport which provide combatant commanders high-speed sealift mobility. EPFs enable rapid projection, agile maneuver and transport of personnel, equipment and supplies over operational distances with access to austere and degraded offload points.
«EPFs continue to be excellent additions to the U.S. Navy force», said Captain Scot Searles, Strategic and Theater Sealift program manager, Program Executive Office (PEO) Ships. «With the delivery of EPF 9 to the fleet, the U.S. Navy continues to provide a variety of capabilities to U.S. operations around the globe».
As versatile, non-combatant vessels, EPFs provide increased operational flexibility for a wide range of activities including maneuver and sustainment, relief operations and flexible logistics support. These vessels are capable of interfacing with roll-on/roll-off discharge facilities and on/off-loading a combat-loaded Abrams Main Battle Tank. The EPFs include a flight deck to support day and night aircraft launch and recovery operations and airline-style seating for 312 embarked forces with fixed berthing for 104. USNS City of Bismarck (EPF-9) will be owned and operated by the Military Sealift Command.
City of Bismarck was constructed by Austal USA which is currently under contract for the construction of three additional EPFs. USNS Burlington (EPF-10) held its keel laying ceremony in September 2017. Additionally, USNS Puerto Rico (EPF-11) and EPF-12 were awarded in September 2016 and are currently in the early stages of production.
As one of the Defense Department’s largest acquisition organizations, PEO Ships is responsible for executing the development and procurement of all destroyers, amphibious ships, special mission and support ships, and special warfare craft.
