On 688's, the pressure hull IS the outer hull from aft of MBT 3A&B all the way to aft elliptical bulkhead at the shaft seals,

The (visible, extremely serious) buckling is confined to the MBT area - though THOSE frames may have pulled and distorted the pressure hull in that area.

Aft of those frames the rest of the hull "appears" to still be in concentric circles.

BUT - Check with a body shop operator about a severe crash to the left front bumper and engine mounts.... Even the doors on the right rear can get distorted and thrown out of alignment.

Here, the whole bow might be thrown to the right - away from the collision.

Thanks. I had made a couple of posts asking and looked for a diagram but couldn't find one.

"Here, the whole bow might be thrown to the right - away from the collision."

Good call, see the hull buckling on starboard side.
