USS Daniel Boone

The contract to build Daniel Boone was awarded to Mare Island Naval Shipyard at Vallejo, California, on 21 July 1961 and her keel was laid down there on 6 February 1962.

[4] During her first major overhaul , like the rest of her class[clarification needed], Daniel Boone was retrofitted with Poseidon C-3 missiles and the associated Mark 88 firecontrol system.

[2] Daniel Boone entered the Tenneco Shipyard at Newport News, Virginia sometime in late 1985 or early 1986 for refit.

This grounding occurred primarily because the OOD (Officer of the Deck), in an attempt to counter act tidal currents, lowered the SPM (Secondary Propulsion Motor) which was quickly and violently snapped off on a sandbar.

This accident, however, significantly delayed her departure from the refit yards because they had to obtain another SPM and repair the hull penetration in Tenneco Shipyard's dry dock.
