USS GROWLER (SSG-577)
USS Growler was built by the Portsmouth Naval Shipyard. Her keel was laid on February 16, 1955 and she was launched on April 5, 1957. She was commissioned on August 30, 1958.
The WWII fleet submarines USS Tunny (SS-282) and USS Barbero (SS-317) had been modified to carry the Regulus missile by adding deck mounted launching ramps and missile hangars. In addition to Growler, two other submarines were built to carry the Regulus missile. USS Grayback (SSG-574) was a sister ship to Growler, commissioned six months earlier. The larger nuclear powered USS Halibut (SSGN-587) was commissioned in 1960. Regulus missiles were also carried by cruisers and aircraft carriers.
With the development of the Polaris ballistic missile, capable of being launched while the submarine is submerged, the Regulus missile was taken out of service. USS Growler and USS Grayback were both decommissioned May 25, 1964 after only six years of service. Grayback was later recommissioned as a transport submarine. Halibut was reclassified as an attack submarine (SSN) in 1965, and served in various roles until 1976. Growler remained in storage at Bremerton, WA for almost 25 years, until she was turned over to the USS Intrepid museum, located in New York City, in 1988. She is the only missile submarine currently open to the public in the United States.
