720 Naval Reactors History Database (subject=S8G;subject-join=exact;smode=simple;brand=default);subject-join%3Dexact;smode%3Dsimple;brand%3Ddefault Results for your query: subject=S8G;subject-join=exact;smode=simple;brand=default Thu, 01 Jan 1970 12:00:00 GMT Simplified view of S8G naval nuclear propulsion plant. A simplified view of the S8G reactor used to power the Ohio-class Trident ballistic missile submarines. The S8G plant's two turbines provide 60,000 shp (thermal power, shaft horsepower), approaching twice the power produced by the S6G plant used to drive the Los Angeles-class attack submarines. Admiral Hyman Rickover, head of Naval Reactors when the Trident submarine was designed in the early 1970s, supported the 60,000 shp plant, which contributed to the submarine's large size (560 feet long, with a submerged displacement of 18,700 tons). Thu, 01 Jan 1970 12:00:00 GMT USS Ohio during her conversion to a guided missile submarine. The USS Ohio at Puget Sound Naval Shipyard, during her conversion from a ballistic to a guided missile submarine. Following this conversion, the Ohio was redesignated SSGN-726. The redesigned submarine is capable of launching cruise missiles and inserting Navy SEALs into combat areas. Mon, 15 Mar 2004 12:00:00 GMT The USS Ohio, first boat in guided missile submarine class. The USS Ohio returns to the Puget Sound Naval Shipyard in Bremerton, Washington following sea trials. The Ohio was converted from a Trident ballistic missile submarine to the first guided missile submarine. Fri, 23 Dec 2005 12:00:00 GMT USS Ohio, the first Trident submarine. The USS Ohio, lead boat in the Ohio ballistic missile submarine class, during her construction at Electric Boat. The Ohio is powered by an S8G reactor. An S8G prototype plant was built at the Knolls Atomic Power Laboratory facility in West Milton, New York; the prototype reactor achieved full power operations in December 1979. The Ohio was commissioned on 11 November 1981, about two and a half years behind schedule. Mon, 01 Jan 1979 12:00:00 GMT
