The Ohio-class nuclear powered ballistic missile submarine USS Alabama (SSBN-731) is being moved "dead-stick" in the sound by a flotilla of tug boats with Mount Rainer in background. U.S. Navy photographed by Mr. By Mass Communication Specialist 2nd Class (AW/NAC) Eric J. Rowley, Fleet Public Affairs Center Det. USS Alabama (SSBN 731) is officially floating again after its 20-month dry-dock period ended Aug. 21. The Alabama was officially dry-docked Jan. 18, 2006. Overall maintenance is scheduled for completion in the spring of 2008, which means the Alabama should be ready to start sea trials, finish the recertification process and return to the Navy as an operational unit. “This is a huge step and a key event,” said Lt. Gary Dunn, Alabama engineering refueling overhaul coordinator (EROC).
