The USS Glenard P. Lipscomb (SSN-685) was a nuclear submarine without class membership in the service of the United States Navy . The boat was named after Glenard P. Lipscomb (1915-1970), a congressman .


The Lipscomb , which is 111 meters long and displacing almost 6500 ts , was designed as a test ship. While most of their technology - such as the weapon systems - was based on the previous Sturgeon class , an experimental drive system was installed. That was also the main reason for the substantial increase of about 20 meters in length compared to this.

The pressurized water reactor is essentially the same as that of the Sturgeons . The shaft was not driven by geared turbines, but by an electric motor , i.e. by means of a so-called turbo-electric drive system. Such a propulsion system was tested on the USS Tullibee (SSN-597) ten years before the Lipscomb , but was ultimately not integrated into later submarines even after the second attempt.

The Lipscomb was the second test ship based on the Sturgeon class after the USS Narwhal (SSN-671) .


SSN-685 was approved in late 1968 and laid down at Electric Boat in June 1971 . After just over two years of construction, the submarine was launched and was christened. Godmother was the widow Lipscombs. The construction cost a total of around 180 million US dollars plus around 30 million dollars for the development of the drive system.

The Lipscomb officially entered service in late 1974. Although she served as a test ship for the turbo-electric drive, she was fully ready for combat and also integrated into the active fleet.

After around 15 years, the Glenard P. Lipscomb was finally decommissioned at the end of 1990. Until 1997 the hull went through the Ship-Submarine Recycling Program in the Puget Sound Naval Shipyard and was dismantled in an environmentally friendly way.
