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

Design

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 (677 ft 6 in). It has a beam of 29.7 metres (97 ft) and a draft of 11 metres (36 ft). The oiler has a displacement of 41,353 tonnes (40,700 long tons; 45,584 short tons) at full load. It has a capacity of 180,000 imperial barrels (29,000,000 l; 6,500,000 imp gal; 7,800,000 US gal) of aviation fuel or fuel oil. It can carry a dry load of 690 square metres (7,400 sq ft) and can refrigerate 128 pallets of food. 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 megawatts (34,800 PS; 34,300 shp).[1]

The Henry J. Kaiser-class oilers have maximum speeds of 20 knots (37 km/h; 23 mph). They were built without armaments but can be fitted with close-in weapon systems. The ship has a helicopter platform but not any maintenance facilities. It is fitted with five fuelling stations; these can fill two ships at the same time and the ship is capable of pumping 900,000 US gallons (3,400,000 l; 750,000 imp gal) of diesel or 540,000 US gallons (2,000,000 l; 450,000 imp gal) of jet fuel per hour. It has a complement of eighty-nine civilians (nineteen officers), twenty-nine spare crew, and six United States Navy crew.[1]

Construction and delivery

Leroy Grumman, the ninth ship of the Henry J. Kaiser class and 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 with a primarily civilian crew on 3 August 1989.

Service history

Leroy Grumman serves in the United States Atlantic Fleet.

In early 2012, she joined several British warships from the Royal Navy including the aircraft carrier HMS Illustrious and fleet flagship HMS Bulwark to partake in Exercise Joint Warrior and other training missions with warships from the United Kingdom, Norway and the Netherlands.[2]
