"On that day, January 8, 2005, the San Francisco had been approximately 360 miles southeast of Guam, traveling at flank speed (more than 30 knots). The navigational charts used by the ship's crew failed to show a seamount, or undersea mountain, protruding from the ocean floor. The sub smashed into it head-on."
