Notice how much fo the bow is gone. See the sounding marking "28" in the damage photo. Then compare it to the pre-damage photo where you see the same marking way back from the bow.

not the same submarine, but you can see how much of the bow is gone

The sonar dome is made of glass reinforced plastic (GRP), not steel like the hull. The remains were probably cut off after she moored. You can even see the bolt holes for it.

In the closeup, what you are looking at is FROM the starboard side of the ship, looking aft towards the port side - which is severely crushed and bent away. Little damage on the upper part of the stbd main ballast tanks at this elevation (28 feet above the keel). Even the paint is unscarred. Underneath?

But the port side? This is where they must have hit vertical wall or spike shaped cliff - it destroyed the port side, but not the stbd steel as bad.

Completely bend and torn away in MBT1B. The are 6 MBT's forwards - each of the three "circular sections is divided in the middle into a port B and and stbd A tank. These MBT's BEGIN immediately after the circular dividing plate (frame) that is visible. Somebody pointed out the "holes" where the plastic (fiberglass, about 1" thick) sonar dome is attached. Those are the "little" black "circles", but each bolt is about 3/4" in diameter, and the bolt head (what's visible) is about 1-1/2" across.

The whole sonar dome is ripped off.

The sonar sphere is a watertight (until the boat hit the bottom!) sphere attached to this plate. It goes forward and holds 4 large electronics racks of transducer connection and wires.

The rectangular hatch is an access opening into these tanks I used all the time when the boat was in drydock or for maintenance.
