USNS Leroy Grumman (T-AO-195)

USNS Leroy Grumman (T-AO-195) is the ninth Henry J. Kaiser-class fleet replenishment oiler of the United States Navy.

Leroy Grumman, the first U.S. Navy ship to bear the name, was laid down at Avondale Shipyard, Inc., at New Orleans, Louisiana, on 6 July 1987 and launched on 3 December 1988.

She entered non-commissioned U.S. Navy service under the control of the Military Sealift Command (MSC) with a primarily civilian crew on 3 August 1989 and currently serves in the U.S. Atlantic Fleet.

The Henry J. Kaiser-class oilers were preceded by the shorter Cimarron-class fleet replenishment oilers. Leroy Grumman has an overall length of 206.5 metres and a displacement of 41,353 tonnes at full load.

It has a capacity of 29 million liters of aviation fuel or fuel oil. It can carry a dry load of 690 square metres and can refrigerate 128 pallets of food. It is fitted with five fuelling stations; these can fill two ships at the same time and the ship is capable of pumping 900K US gallons of diesel or 540K US gallons of jet fuel per hour.

The ship is powered by two 10 PC4.2 V 570 Colt-Pielstick diesel engines that drive two shafts; this gives a power of 25.6 MW. They have maximum speeds of 20 knots.

The oilers were built without armaments but can be fitted with close-in weapon systems (CIWS). The ship has a helicopter platform but not any maintenance facilities.

The ship has a complement of eighty-nine civilians (nineteen officers), twenty-nine spare crew, and six U.S. Navy crew.
