The D2G reactor was a naval reactor used by the United States Navy to provide electricity generation and propulsion on warships. The D2G designation stands for:

History[edit]

This model of nuclear reactor was installed on the Bainbridge, Truxtun, California, and Virginia classes of guided missile cruisers; the only nuclear-powered cruiser in the United States Navy not equipped with a D2G reactor was the world's first nuclear cruiser, the USS Long Beach (CGN-9), which used a C1W reactor.[1]

It is known that USS Bainbridge's reactors were refueled three times, and USS Truxtun's were refueled twice.[1]

Operation[edit]

The Bainbridge, Truxtun, California and Virginia class ships all used two of the D2G reactors, each rated for a maximum thermal output of 148 megawatts (198,000 hp), with two steam turbines which drove two shafts, each generating between 30,000 shaft horsepower (22,000 kW) and 35,000 shaft horsepower (26,000 kW);[2][1] each D2G reactor was 37 feet (11 m) long, 31 feet (9.4 m) wide, and weighed 1,400 tonnes (1,400 long tons; 1,500 short tons). One reactor was located in the aft of the hull, the other in the fore; the California class' reactors were replaced by D2W reactors, both rated at 165 megawatts (221,000 hp), in the early 90s.[1]
