USS Tennessee (SSBN 734) is a United States Navy Ohio-class ballistic missile submarine and the first submarine of the U.S. Navy to be named for Tennessee the 16th state.

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 January 7, 1982. Her keel was laid down there on June 9, 1986.

December 13, 1986 USS Tennessee (SSBN 734), the first Trident II (D5) submarine, was launched during ceremonies at Electric Boat Division of General Dynamics, Groton, Conn. Mrs. Landess Kelso, wife of Admiral Frank B. Kelso, Commander, U.S. Atlantic Fleet, was the ship’s sponsor.

November 18, 1988 The Tennessee was delivered 43 days ahead of schedule and below the target cost to the Navy.

USS Tennessee was commissioned on December 17, 1988, with Capt. D. Witzenburg in command of the Blue Crew and Capt. Kenneth D. Barker in command of the Gold Crew.

January 15, 1989 SSBN 734 arrived at its new homeport of Kings Bay, Ga. The Tennessee's ceremonial arrival marked the beginning of Trident operations in the Atlantic fleet.

March 21, The Navy's first Trident II Performance Evaluation Missile (PEM-1) was launched from USS Tennessee off the coast of Cape Canaveral, Fla. As a result of the failure of this flight test, several modifications were made to strengthen and protect the first-stage nozzle.

August 2, The Tennessee successfully launched the Navy's second Trident II (D5) Performance Evaluation Missile.

August 15, The ninth Ohio-class ballistic missile submarine launched the Navy's third PEM-1. This flight was unsuccessful because of higher than expected water pressures on the first-stage nozzle (like the first PEM) and demonstrated that additional fixes were necessary.

October 26, SSBN 734 completed a Post Shakedown Availability (PSA) at Electric Boat Division of General Dynamics, Groton, Conn.

December 4, The Tennessee successfully launched the Navy's fourth Trident II Performance Evaluation Missile. This missile incorporated all fixes necessary to preclude the failures seen in PEM flights 1 and 3. Also successfully launched missiles on Dec. 13 and 15th.

The seventh and eight Trident II Performance Evaluation Missile were successfully launched by the Blue Crew off Cape Canaveral, Fla., January 15 and 16, 1990.

January 29, The Director, Strategic Systems Programs, certified the Trident II (D5) Strategic Weapon System ready for Operational Test Phase II and commenced the start of Demonstration and Shakedown Operation on the USS Tennessee.

February 12, USS Tennessee (Blue) successfully launched the first Trident II missile of a two-missile ripple launch during a Demonstration and Shakedown Operation (DASO-01) off Cape Canaveral. This was the ninth Trident II submarine launched missile. The second half of the two-missile launch was the 10th Trident II submarine-launched missile and the last Performance Evaluation Missile (PEM) launched.

March 23, The Strategic Weapons Facility, Atlantic, Kings Bay, Ga., completed the outloading of 24 tactical Trident II (D5) missiles on board the Tennessee. The loadout and acceptance of the missiles by SSBN 734 signaled the achievement of Initial Operational Capability for the Trident II Program. Reaching this key milestone completed a full-scale development program lasting over 6 years. The Trident II Development Program met all performance requirements and was completed under the original budget estimate set at the beginning of the program. USS Tennessee began the first Trident II patrol March 29, 1990.
