At her solemn decommissioning ceremony conducted at Pier #4 at the Submarine Base, New London on 1 October 1970, there were many present who could remember Sea Robin’s gallant days in her great past. Among those delivering final salutes to Sea Robin were her first Commanding Officer, Capt. Paul C. Stimson and Rear Admiral Oliver H. Perry Jr., Commander of Submarine Flotilla Two.

Chaplain Lt. Cmdr. Robert Gibney delivered the invocation address that day, saying "If old boats could talk, Sea Robin would tell how she ran with the best of them and outran most of them. There is no heaven for an old and tired boat. Only the memories of the lives shaped within her hull live on."
