Laramie, the seventeenth ship of the Henry J. Kaiser class, was laid down at Avondale Shipyard, Inc., at New Orleans, Louisiana, on 10 January 1994 and launched on 6 May 1995. She was one of only three of the eighteen Henry J. Kaiser-class ships—the other two being USNS Patuxent (T-AO-201) and USNS Rappahannock (T-AO-204)—to be built with a double bottom in order to meet the requirements of the Oil Pollution Act of 1990. Hull separation is 6 feet (1.8 m) at the sides and 6 feet 6 inches (1.98 m) on the bottom, reducing her liquid cargo capacity by about 21,000 barrels (3,300 m3) from that of the 15 ships of her class without a double bottom.

Laramie entered non-commissioned U.S. Navy service under the control of the Military Sealift Command with a primarily civilian crew on 7 May 1996, the last of the eighteen Henry J. Kaiser-class ships to enter service. She serves in the United States Atlantic Fleet.

Design

edit

The Henry J. Kaiser-class replenishment oilers were preceded by the shorter Cimarron class. Laramie 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 159,000 imperial barrels (26,000,000 L; 5,700,000 imp gal; 6,900,000 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]
