Ohio Class Guided Missile Submarine USS Florida (SSGN-728) with missile tubes open

On Feb. 10, 2005, USS Florida (SSGN 728) undocked, thereby achieving a major milestone in the overhaul and conversion process for the guided-missile submarine (SSGN) program. The milestone was achieved one week ahead of the scheduled date of Feb. 16. Florida was the second of four ballistic missile submarines (SSBN) being converted into state-of-the-art, multimission, guided-missile submarines. Florida's conversion was, as of then, more than 49 percent complete, and the boat was scheduled to return to the fleet April 1, 2006.
