K-55 class submarine

An excellent find but unfortunately it was not sunk as part of a military operation. We need a wreck of a ship that was sunk by an enemy.

Clarification: "sunk by an enemy" is one acceptable form of "military operation". Sinking while testing weapons is another.

The main point is to avoid ships that have been abandoned, static display, converted to other uses, scrapped when no longer useful, sunk at anchor, etc.

I want ships that went BOOM. In a few cases the BOOM destroyed the ship and the decision to scuttle the ship for safety came after the BOOM.
