Rumor has it that the USSR sub nocked the conning tower off the Scorpion.

The US Navy built the NR-1, the worlds smallest nuclear sub, to search for the Thresher and the Scorpion in 1960.The submarines are not in a million pieces the reactor compartment is intact and no radiation has been released. The boats had manufacturing problem.

[El Gran Salseron]

The Thresher nor the Scorpion had a “conning tower”. The old diesel boats had conning towers which were shaped like a rounded off barrel as part of the pressure hull but outside of the actual full pressure hull inside the sail. Those two classes of nukes did away with the conning tower. You may be referring to the “Sail”. Whether or not knocking the sail off would make it sink is questionable. A catastrophic event like that would probably make it sink but that is not absolute.
