San Francisco sailed, and the Group's own requirements are that it be to the ship three to five days before sailing." Ultimate responsibility for navigational safety rests with the ship's captain and crew, not the Subnote; however, "The report found that the Subnote did route the San Francisco through the area where it hit the seamount." San Francisco had recently replaced her nuclear fuel and she was thus expected to remain in service until 2017, so the Navy determined that repair of the submarine was in its best interests. Temporary repairs were made in Guam to provide watertight integrity and forward buoyancy so that the boat could safely transit to another location for more extensive repairs. San Francisco steamed to Puget Sound Naval Shipyard (PSNS) in Bremerton, Washington via Pearl Harbor, Hawaii, where she arrived on 26 August 2005. In June 2006, it was announced that San Franciscos bow section would be replaced at the Puget Sound Naval Shipyard with the bow of , which was soon to be retired. San Francisco is four years older than Honolulu, but she had been refueled and upgraded in 2000–2002. The cost of her bow replacement has been estimated at $79 million, as compared with the estimated $170 million to refuel and overhaul the nuclear reactor of Honolulu. On 10 October 2008, San Francisco undocked after a successful bow replacement at the Puget Sound Naval Shipyard. The dry-docking project involved cutting more than of forward ballast tanks and sonar sphere off the former USS Honolulu and attaching them to San Francisco. San Francisco completed repairs and sea trials in April 2009, then shifted homeport to Naval Base Point Loma, San Diego, California. Final deployment and conversion San Francisco returned to Point Loma from her sixth deployment in October 2016. Her change of command and farewell ceremony was held on 4 November 2016, after which she was homeported to Norfolk for conversion to a moored training ship (MTS) at the Navy's Nuclear Power Training Unit in Charleston, South Carolina. On 11 May 2017, the ship was placed in "'In Commission Special' - stand down for MTS conversion", a 32-month long process that was expected to begin in early 2018. The conversion was completed in mid-2021 and on 16 Aug she was moved from Norfolk to Charleston. She was decommissioned on 15 May 2022.
