KITTERY – The submarine USS Hyman G. Rickover, named for the admiral known as the father of the nuclear Navy, arrived Friday at the Portsmouth Naval Shipyard for inactivation.

The Rickover, with a crew of 12 officers and 115 enlisted sailors, recently completed 22 years of service with a six-year deployment to the North Atlantic.

The fast attack sub was launched in 1983 in Connecticut, the 22nd of the Los Angeles class vessels.

The Rickover had the distinction of being the only one in the class to be named after a person instead of a city. Rickover served 63 years in the Navy before being forced to retire in 1982. He died four years later.
