No torpedo hits from the K-21 submarine attack were actually recorded on the German squadron near the Tirpitz.

Notes on verification

Confirmed by multiple independent naval history sources (Kbismarck.com, Uboat.net, USNI Proceedings) and detailed technical analysis citing Soviet naval historian Platonov. Consistent across Soviet, German, British, and American accounts, despite original Soviet wartime propaganda claiming a hit.
