No torpedo hits were actually recorded on the German squadron during K-21's attack on the Tirpitz on 5 July 1942.
Notes on verification
Confirmed by multiple independent specialist sources (kbismarck.com, uboat.net, warhistory.org) and physical evidence from postwar hull inspection. Contrary claims trace to Soviet wartime propaganda and Lunin's report, which are discounted by historians.
