USS Seawolf (SSN-575) was the third ship of the United States Navy to be named for the seawolf, the second nuclear submarine, and the only US submarine built with a liquid metal cooled (), beryllium-moderated [2] [3] nuclear reactor, the S2G. [4]
[2]: 189 Other submarines were used for this role, including USS Parche (SSN-683), USS Richard B. Russell (SSN-687), and USS Seawolf (SSN-575). Seawolf was almost lost during one of these missions—she was stranded on the bottom after a storm and almost had to use her self-destruct charges to scuttle the ship with her crew. [4]
USS Seawolf (SS-28), renamed USS H-1 before launching, was the lead ship of the H-class of submarine. Commissioned in 1913, she ran aground and sank in 1920; USS Seawolf (SS-197) was a Sargo-class submarine. Commissioned in 1939, she was successful during World War II until she was lost to friendly fire in 1944; USS Seawolf (SSN-575) was the ...
An S2G was the initial power plant of USS Seawolf.This was one of three sodium cooled reactors (the core was moderated) ordered for the Seawolf program at the same time as three PWR units were ordered to support the USS Nautilus program; In each case, one reactor was land-based for training and research, one intended for installation on a submarine, and one spare.

Particularly significant was the performance of nuclear-powered submarines with the U.S. Navy's first two such vessels, the USS Nautilus (SSN-571) and USS Seawolf (SSN-575), participating in Operation Strikeback.
On April 1, 1958, SUBRON 10 had the U.S. Navy's first three nuclear powered submarines (USS Nautilus, USS Seawolf and USS Skate) assigned to it. Among the historic submarines assigned to the squadron were Nautilus (SSN-571) (1958– c. 1975 ), Seawolf (SSN-575) (1958–1970), Skate (SSN-578) (1958– c. 1969 ), USS Skipjack (1959–1969) and ...
This nuclear reactor was constructed by General Electric as a prototype for the USS Seawolf submarine. It was a liquid metal cooled reactor using pure sodium to cool the core instead of water, because the higher temperature of liquid sodium (compared to pressurized water) enabled the production of more superheated steam in the steam generators.
