U.S. Nuclear Sub Runs Aground

About 400 miles south of Guam, a Los Angeles-class nuclear attack submarine, USS San Francisco, ran aground during submerged operations. The U.S. Navy reports that one sailor is critically injured. The boat is on the surface underway toward Guam, its home port, with no apparent damage to the reactor plant.

A simple look at the map indicates that the water in the described location is miles deep. It sure doesn't seem possible for a submarine to hit bottom unless there was an uncharted seamount or the sub was operating close to an island.

1 Hmmm, an attack Sub needing body and fender repair . . Betcha somebody else's Sub needs some fixing too. Ran aground, yeah right. With all the sensing devices aboard an Attack Sub there's no way . . unless the entire crew was asleep. Betcha either the Russians are still floating their Boomers in the West Pacific or the Chinese are putting something bigger than their Electric Boats in the water and going out for longer drives.

2 Sonar operator asleep? No other way this could happen.

3 A sonar operator can't hear a sea mountain up ahead. The sonar is passive, i.e., it just listens to the ocean around it. At that speed (35 mph) all the machinery equipment noises pretty much render the sound transducers useless. They're travelling soley by navigational charts. If those charts are wrong, as was probably the case for SAN FRANCISCO, then any uncharted hazards can only be found the hard way.
