A Russian Cruise-Missile Submarine Holds a Terrifying Record: It Sank Twice
K-429 had not suffered irreparable damage; she was refloated, repaired, and returned to service. Her second life was brief, however; in September 1985, the boat sank at dockside with the loss of one crewmember. The causes of the second sinking remain hazy, but appear unrelated to the first incident. K-429 was again raised, but not returned to sea; for the rest of her career she served as a training hulk. She was scrapped, along with her sisters, in the 1990s.
