Submarine Crash Photos

I came across an old story about USS San Francisco, SSN-711, hitting an uncharted undersea mountain while traveling at high speed about 500 ft deep.

Here are the photos:



I know that the standard submarine alloy is HY-80, a weldable high strength steel with a yield of about 80ksi.

So, from the damage, does anyone want to try to figure the speed it was traveling at?
