US Navy takes delivery of fleet oiler Earl Warren

The US Navy took delivery of a new John Lewis-class fleet replenishment oiler (T-AO) on Tuesday, May 7.

The delivery of USNS Earl Warren follows the successful completion of integrated sea trials to test the readiness and capability of the ship and to validate requirements.

The John Lewis-class ships are based on commercial design standards and will provide underway replenishment of fuel to US Navy ships at sea. These ships were all built by General Dynamics NASSCO and are part of the navy’s Combat Logistics Force.

The vessel will provide diesel fuel and lubricating oil and small quantities of fresh and frozen provisions, stores, and potable water to US Navy ships at sea, as well as jet fuel for aircraft. The ship also boasts the capacity to carry up to 157,000 barrels of oil, a significant dry cargo capacity, and aviation capability courtesy of a helicopter deck.

As an auxiliary ship, Earl Warren is fitted only with defensive armament consisting of multiple Browning M2 12.7mm crew-served machine guns.

The T-AO honours the late Earl Warren, a former Chief Justice of the United States Supreme Court.
