Construction and commissioning

edit

Tennessee's construction was authorized in fiscal year 1980, and the contract to build her was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut, on 7 January 1982. Her keel was laid down there on 9 June 1986. She was launched on 13 December 1986, sponsored by Mrs. Landess Kelso, and commissioned on 17 December 1988, with Captain Dennis Witzenburg in command of the Blue Crew and Captain Kenneth D. Barker in command of the Gold Crew.

The Tennessee was the first Ohio-class submarine commissioned capable of launching the Trident II ballistic missile (D5). On 21 March 1989, off the coast of Cape Canaveral, Florida, the Tennessee attempted the first submerged launch of the D5 which failed four seconds into the flight. Once the problem was understood, relatively simple changes were made and the first successful submerged test launch of a D5 missile was completed on 2 August 1989 by the Tennessee's Gold Crew.

Service History

edit

In 2021, Tennessee entered drydock to undergo a major overhaul at TRF Kings Bay, one that the facility says is the longest and most extensive work package it has executed in its history.

In December 2022, Tennessee conducted a training exercise in the Atlantic with HMS Victorious (S29).

Commander of the United States European Command, General Christopher G. Cavoli, embarked the Tennessee in July 2023 alongside William J. Houston who, at the time, held the position of Commander, Submarine Force Atlantic. They were given a formal tour by the crew.

In July 2023, Tennessee made a scheduled port visit to HMNB Clyde in Scotland. Simultaneously, the USS Kentucky (SSBN-737) pulled into the Busan Naval Base in South Korea. This was allegedly conducted as a show of force and to show the capabilities of the U.S. SSBN Fleet. The following year, July 2024, the Tennessee made yet another port call to HMNB Clyde. Prior to this, it had conducted operations in the Norwegian Sea alongside the USS Normandy (CG-60), where it was reported that the Norwegian Flag Commodore Trond Gimmingsrud embarked Tennessee for a demonstration of SSBN operations. During it's transits into HMNB Clyde, HMS Northumberland (F238) was seen escorting the Submarine.

Tennessee was awarded the Battle Effectiveness Award in 2023.
