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:
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, which used a C1W reactor.
It is known that USS Bainbridge's reactors were refueled three times, and USS Truxtun's were refueled twice.

Operation

The Bainbridge, Truxtun, California and Virginia class ships all used two of the D2G reactors, each rated for a maximum thermal output of, with two steam turbines which drove two shafts, each generating between and. Each D2G reactor was long, wide, and weighed. 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, in the early 90s.
