The Soviet submarine K-21 was commanded by Captain Second Rank Nikolai Lunin during the attack on the Tirpitz on 5 July 1942.
Notes on verification
Multiple independent sources (Wikipedia, Warfare History Network, topwar.ru, Axis History Forum) confirm the date, submarine, commander, and rank at time of attack. Minor discrepancy in uboat.net's rank listing is explained by promotion timeline, not a contradiction.
