| - USS Ethan Allen (SSBN-608), lead ship of her class, was the second ship of the United States Navy to be named for American Revolutionary War hero Ethan Allen. Ethan Allen's keel was laid down by the Electric Boat Corporation of Groton, Connecticut. She was launched on 22 November 1960, sponsored by Mrs. Robert H. Hopkins, great-great-great-granddaughter of Ethan Allen. The ship was commissioned on 8 August 1961, with Captain Paul L. Lacy, Jr., commanding Blue Crew and Commander W. W. Behrens, Jr., commanding the Gold Crew.

| - USS Ethan Allen (SSBN-608), lead ship of her class, was the second ship of the United States Navy to be named for American Revolutionary War hero Ethan Allen. Ethan Allen's keel was laid down by the Electric Boat Corporation of Groton, Connecticut. She was launched on 22 November 1960, sponsored by Mrs. Robert H. Hopkins, great-great-great-granddaughter of Ethan Allen. The ship was commissioned on 8 August 1961, with Captain Paul L. Lacy, Jr., commanding Blue Crew and Commander W. W. Behrens, Jr., commanding the Gold Crew. Ethan Allen (Navy hull design SCB-180) was the first submarine designed as a ballistic missile launch platform. (The earlier George Washington class were converted attack submarines.) She was constructed from HY80 steel (high yield, yield strength), and was fitted with the Mark 2 Mod 3 Ships Inertial Navigation System (SINS). At launch, she was outfitted with Polaris A-2 (UGM-27B) submarine-launched ballistic missiles (SLBMs) and Mark 16 Mod 6 torpedoes; the torpedo fire control system was the Mark 112 Mod 2. The A-2s would be replaced with Polaris A-3s and their gas/steam ejection launch gear and Mark 80 fire control systems during 1965, while in the 1970s these would be replaced with Polaris A-3Ts. In addition, Ethan Allen was updated with Mark 37 and (later) Mark 48 torpedoes during her operational lifetime. On 6 May 1962, Ethan Allen, under Captain Lacy and with Admiral Levering Smith aboard, launched a nuclear-armed Polaris missile that detonated at over the South Pacific. That test (Frigate Bird), part of Operation Dominic I, was the only complete operational test of an American strategic missile. The warhead hit "right in the pickle barrel." USS Carbonero (SS-337) and USS Medregal (SS-480) participated in the test, about 30 miles from the impact point. To make room for the new Ohio-class submarine ballistic missile submarines within the limitations of SALT II, Ethan Allen's missile tubes (and those of other earlier ballistic missile submarines) were disabled, and she was redesignated an attack submarine (hull number SSN-608) on 1 September 1980. Ethan Allen was decommissioned on 31 March 1983 and stricken from the Naval Vessel Register on 2 April 1983. Her hulk was tied up in Bremerton, Washington, until entering the Nuclear Powered Ship-Submarine Recycling Program. Recycling was completed on 30 July 1999.
