Mustang class subs do this all the time.

USS San Francisco.

In 2005, the nuclear attack submarine USS San Francisco suddenly stopped dead in its tracks. The ship's crew were thrown about, some over distances of 20 feet, and the majority of the 137-member crew suffered one injury or another—including one that would later prove fatal. Further inspection would explain what happened, and reveal that the submarine's bow looked like a crushed soda can. USS San Francisco had run into an undersea mountain.

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.

Oh look, an uncharted undersea mountain.

That's what that was !

The USS Gurnard hit a mountain in 89 while I was on the Mckee. I could have gone over to take a look at it when it was in drydock in the San Onofre but I didn't. I know someone who was on it when it hit. If I ever get around to doing another cross country road trip, I'm going to try to hook up with my shipmates from back then and maybe I can get him to tell me about it.

It was probably the scariest part of his career.

this is a 637 class but I don't know if its the Gurnard

- It's either propaganda or a mishap. It's possible they dented a Chinese sub or ship bottom but if they did, I think we'd know.
The Chinese would be complaining about it very loudly.

What else could they hit under water?

I wouldn't go playing chicken with a Chinese sub. They're crazy bastards.

Or... next to the emergency exit while you're underwater LOL

Its amazing how bad nautical charts still are. Especially for areas less traveled. There is an atoll in the pacific (name escapes me) that is plotted over a mile out of position, and completely inaccurate shape. Anything below the water is a whole new level of inaccuracy. A lot of time and money is spent on mapping high use lanes and ports. But everything else is probably charted long before GPS.

If you take sat photos and superimpose them onto drawn charts, its shocking how bad charts really are. Im surprised there aren't nautical charts based entirely off of satellite imaging. I would pay good money for that.

Don't think I ever posted this but back in 1969 when I was on the USS Enterprise we were moving from Newport News Shipyard/Norfolk NS out west to Alameda Naval Air Station, we had to go around South America as the carrier was too wide for the canal. As we were going through Cape Horn the weather got terrible, really, really terrible and we had to make sure everything was really well secured! About 0200 (2:00 AM for the civilians) we heard the 1MC start to say something, all that came out was "brace...." and the carrier STOPPED DEAD from 15 knots! It appears we hit a huge wave, the bridge watch standers said it was at least 30 feet higher than the flight deck, maybe more. I was just going into the enclosed operating station (EOS) and got my right side and side of my head really banged hard, slight concussion I found out later, our throttle valve watch had his face smashed with a broken nose and about 250 crew were hurt it seems. There had been some guys on the flight deck looking at lights along the "end of the world" and they flew 50+ feet on non-skid which had to have really hurt. Captain Peterson was on the bridge and actually had his safety belt on so he stayed in his chair but other watch standers flew everywhere. But we made it to California thank goodness!

thank you John and others for posting such fascinating stories, they're a pleasure to read

This line so casually written made me smile, reads like 'whoops there is a continent in the way, we'll just go round it'

No army, navy or air force is a match for mother nature no matter the size of their military might or the size of their fight

Problem is the earth changes a lot more than most people will ever get to realize.
See post 5.
The amount of work my uncle had to do with the major Japan quake that hit that reactor was off the charts.

Passive sound detection is for silent running.....full out balls to the wall at 30 plus knots every bell and whistle is pulsing, HERE I FOOKINGCOM and get out my way. That Captain is gonna get a retirement rickitklike.

There are if you want to pay for it. My Garmin radar, sounder, GPS bundle can interface and overlay satelite imagining onto my chart plotter. I don't pay for that service so I down load charts to my plotter. It's amazing how off the digital files are so I still use paper charts and a compass with the elctronics to verify.

Great story. I love you when you guys share military stories of any kind.
