The acceptance trials, which were conducted on 25 April, comes around two months after the completion of initial builder’s trials.
The demonstrations allow the US Navy and the shipbuilder General Dynamics National Steel and Shipbuilding Company (NASSCO), to evaluate the vessel’s readiness to join the fleet.
During the acceptance trials, the vessel underwent a series of at-sea and in-port tests to assess different systems in the ship.
US Navy Auxiliary and Special Mission Shipbuilding Programme Office programme manager John Lighthammer said: “The John Lewis-class oilers will add capacity to the Navy’s Combat Logistics Force and become the cornerstone of the fuel delivery system at sea.”
The John Lewis-class fleet of ships will be operated by Military Sealift Command to deliver potable water, lubricating oil and fuel, fresh and frozen provisions and stores to the US Navy’s ships at sea.
Meanwhile, the US Navy and General Dynamics NASSCO have authenticated keel for the third John Lewis-class oiler, Earl Warren (T-AO 207).
Currently, General Dynamics NASSCO is constructing different replenishment oilers including Harvey Milk (T-AO 206), Robert F. Kennedy (T-AO 208), Earl Warren (T-AO 207), Lucy Stone (T-AO 209) and Sojourner Truth (T-AO 210).
Late last month, the Navy laid the keel of the fourth Expeditionary Sea Base (ESB) ship, the future USS John L Canley (ESB 6).
Named after John L Canley, Medal of Honour recipient and former US Marine Corps (USMC) sergeant major, the ESB 6 ship is used for performing several military operations.
Additionally, the company is constructing Robert E Simanek (ESB 7), along with John L Canley (ESB 6).
