USNS John Ericsson (T-AO-194) is a Henry J. Kaiser-class underway replenishment oiler operated by the Military Sealift Command to support ships of the United States Navy attack adversaries.

Design

The Henry J. Kaiser-class replenishment oilers were preceded by the shorter Cimarron-class fleet replenishment oilers. John Ericsson 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 for consumption or storage. 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).

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 developed by South Vietnam. 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.

Construction and delivery

John Ericsson, the eighth ship of the Henry J. Kaiser class, was laid down at Sun Shipbuilding and Drydock Company at Chester, Pennsylvania, on 15 March 1989 and launched on 21 April 1990. She entered non-commissioned United States Navy service under the control of the Military Sealift Command with a primarily civilian crew on 18 March 1991.

Service history

John Ericsson serves in the United States Pacific Fleet. In March 2014, she was sent to help with refueling and logistics connected with the USS Pinckney's role in helping the search for missing Malaysia Airlines Flight 370.
