The Emory S. Land-class submarine tender is a class of submarine tenders of the United States Navy .
history
The Emory S. Land class is a slight modification of the previous L. Y. Spear class . The USS Emory S. Land (AS-39) was commissioned as the first ship of the class together with the second in 1974, the last unit in 1977. An originally planned fourth ship of the class was not built. The planning yard was the Norfolk Naval Shipyard , and all three tenders were built by the Lockheed Shipbuilding and Construction Company . The cost was around $ 130 million per ship from the 1972 and 1973 budgets for the first two units. The fourth unit would have cost $ 260 million in 1977.
The ships were put into service between 1979 and 1981. In 1999 the first of the three ships, AS-41, was decommissioned. In 2007, AS-39 was withdrawn from the Mediterranean and stationed on the US Pacific coast, AS-40 is located in Apra Harbor , Guam.
technology
The ships of the class are 197.8 meters long and 25.9 meters wide. They displace around 23,000 tons. They were specially designed to supply the Los Angeles class submarines . Each tender can take four submarines alongside and supply them with food and weapons. The ships have three cranes for this purpose, and a boom can also be used to supply a third boat on each side in calm harbor water. The ships have 13 decks in the hull.
The drive consists of two tanks with a connected gear turbine , which together act on a propeller. The system has an output of 20,000 shaft horsepower and the tenders can reach speeds of around 20 knots.
The armament is limited to 20- and 40-mm anti-aircraft guns, an AN / SPS-55 from Raytheon is on board as radar .
