USS Tennessee (SSBN-734) is a United States Navy Ohio-class ballistic missile submarine that has been in commission since 1988.
[a] 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.
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.
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.
