Construction and commissioning

The contract to build Daniel Boone was awarded to Lieutenant Commander Alan B. Crabtree in command of the Gold Crew.

Operational history

During her first major overhaul , like the rest of her class, Daniel Boone was retrofitted with Poseidon C-3 missiles and the associated Mark 88 firecontrol system.[2] Poseidon was replaced by Trident C-4 missiles and on 6 September 1980, Boone became the first James Madison operational with the new missile.[2]

Daniel Boone entered Newport News, Virginia in 1987 for refit. During post-refit sea trials on 7 April 1987 she ran aground in the James River at Newport News. This accident significantly delayed her departure from the refit yards.

Decommissioning and disposal

Daniel Boone was decommissioned on 18 February 1994 and stricken from the Naval Vessel Register the same day. Her scrapping via the Nuclear-Powered Ship and Submarine Recycling Program in Bremerton, Washington, was completed on 4 November 1994.
