The Los Angeles-class fast-attack submarine USS San Francisco (SSN 711) in dry dock to assess damage sustained after running aground approximately 350 miles south of Guam Jan. 8, 2005.90 Percent Of The Crew Was Injured -- Strategy Page
September 19, 2008: Three and a half years after the American submarine USS San Francisco hit the top of an underwater mountain, the medical report has been released. The collision, of a sub moving at over 50 kilometers an hour, smashed the sonar equipment that fills the bow (front) of the sub, as the boat careened off to one side. The sub's sudden change of speed and direction was unexpected by the crew. Thus 90 percent of the 138 man crew were injured. One sailor later died. Most of the injuries were minor, but a third of the crew had serious problems (nine had broken bones, two had dislocated shoulders, nine had concussions and 23 had cuts). Fortunately, the two sailors with medical training were not injured, and were able to prevent all but one of the injuries (a bad concussion) from getting worse. The navy is used its study of the San Francisco medical situation to make changes in how subs are equipped, and sailors trained, to deal with large scale injuries. The navy also noted that 15 percent of the crew still had psychological problems months after the accident. This is not unusual for sailors involved in a large scale accident.
But there were other reasons for poor morale among the San Francisco sailors. The sea mount the sub hit had been spotted by survey satellites in 1999 and 2004, but the intelligence agency responsible, the National Geospatial-Intelligence Agency, said it didn't have the money to update naval charts. Neither did the navy, or anyone else. Thus American submarines were allowed to continue moving around amidst all manner of uncharted hazards. Instead, the sailors on duty when the San Francisco hit the sea mount were punished for not having taken more frequent depth soundings (which would have indicated they might be approaching an obstacle), or consulting another map (than the one originally used) that showed a possible sea mount five kilometers from where they actually collided with one.

My Comment: It is amazing that the sub was not lost.
