GE Gas Turbine Engines To Power Navy Destroyers The General Electric Company, Evandale, Ohio, has been awarded a multi-year sub- contract with a potential value of $130 million by Litton Industries to provide high perform- ance marine gas turbine engines for 30 U.S. Navy Spruance-class destroyers. This initial award covers the engines for the first three ships funded to date and totals $31.3 million. The award was announced by Ellis B. Gard- ner, Litton senior vice president, who stated: "This is the largest of several major subcon- tracts to be awarded on this important nation- al defense effort to produce these advanced multi-mission U.S. Navy destroyers. It is one of the many substantial contracts that will be awarded in the months ahead to hundreds of companies throughout the United States. Con- tracts worth more than 56 percent of the dollar value of each ship will be granted for the purchase of components, systems, and ma- terials." Litton recently received a multi-year con- tract from the U.S. Xavy to produce 30 of these advanced destroyers. The total ceiling price under the contract for all 30 ships is $2.14 bi'lion. Three ships were initially funded by 1970 appropriations providing for a ceiling of $214 million. For fiscal year 1971, $506.8 million has been approved by Congress to build six additional ships. The contract pro- vides for funding the ships in five consecutive procurement increments, each subject to Con- gressional approval, from FY 1970 through 1974. These Spruance-class destroyers will be the first major U.S. Navy combatant ships to use marine gas turbine power plants for main pro- pulsion systems. The first ship, the DD-963, is scheduled for delivery in 1974. The new class HOSE McCAIMN TELEPHONE COJNC.

Spruance, who led Navy forces in the historic victory at Midway in World War II. Each destroyer will be powered by four LM2500 gas turbine engines. This unit is a compact gas turbine combining high compo- nent efficiency and increased operating tem- peratures to produce low operating costs and high performance, and is rated in the 20,000 horsepower class. Gas turbine systems were selected by Litton after comparative life cycle cost analysis studies. The marine gas turbine has a rapid cold-plant start-up capability and is combined with controllable pitch propellers for improved ship maneuverability. The General Electric LM2500, a compact, high perform- ance, 20,000-hp class marine gas turbine engine, has been selected by Litton Industries to power the Navy's new Spruance-class destroyers. Four LM2500 turbines will power each Spruance-class destroyer, the first major war- ship in the U.S. Navy to use marine gas turbines for propulsion. The performance capability of the General Electric LM2500 marine gas turbine engine to be used on these destroyers has already been demonstrated in more than 5,000 hours of operation at sea aboard the all-gas turbine- powered ship, the Admiral William M. Callag- han. The Callaghan is a commercial transport in operation under contract to the Military Sealift Command. The Spruance-class, the first general purpose destroyer production program since the late 1950s, will be the backbone of the U.S. Navy's destroyer forces in the 1970s and beyond. The primary mission of these ships is antisub- marine warfare, including operations as an integral part of Carrier Task Forces. The de- stroyers were designed by Litton Ship Sys- tems' advanced marine technology center at Culver City, Calif. The ships will be series- produced in Litton Ship Systems' new mecha- nized ship manufacturing facility at Pasca- goula. Miss. The new ship production plant, one of the most advanced in the world, will manufacture the destroyers using advanced modular techniques. Litton Industries, headquartered in Beverly Hills, Calif., is a major multinational corpora- tion specializing in products, systems and services for business, defense, marine, indus- trial, and professional markets.

These innovative and highly-automated vessels will be complex weapon systems incorporating missiles, rocket-assisted torpedoes, electronic warfare equipment, automated gunfire control equipment, multipurpose heli- copters and a wide range of ship support systems. Anti- submarine warfare is the primary mission of the new vessels, but they can also carry out naval gunfire mis- sions in support of amphibious assault and land forces. 16 Maritime Reporter/Engineering News
