USS San Francisco: The Submarine That Hit An Underwater Mountain At Full Speed With 137 Crew Aboard

USS San Francisco: The Submarine That Hit An Underwater Mountain At Full Speed With 137 Crew Aboard On January 8, 2005, USS San Francisco, a Los Angeles-class nuclear attack submarine, was transiting submerged at 525 feet depth off the coast of Guam when her bow collided catastrophically with an uncharted underwater seamount. Traveling at flank speed of thirty-three knots, the submarine’s bow was compressed violently against the rocky mountain face, crushing the sonar dome and flooding the forward compartments. One sailor was killed, with ninety-eight others injured, as the crew scrambled to stabilize the submarine and make an emergency surface. The collision exposed critical navigation failures—despite the mountain being marked on paper charts aboard the submarine, the hazard was missing from electronic navigation data relied on during the transit.
