Vepr (K-157) (Russian: literally means "wild boar") is a Project 971 Schuka-B (also known by the NATO reporting name "Akula-II") class nuclear powered attack submarine of the Russian Navy. Her keel was laid down on 16 June 1990 by Sevmash. She was launched on 10 December 1994, commissioned on 25 November 1995, and homeported in Gadzhievo. Shortly before midnight, 10 September 1998, Vepr was in port at Severomorsk. Alexander Kuzminykh, a 19-year-old seaman who was being detained on punishment charges, broke out from his quarters, killed his guard by stabbing him with a chisel, then seized his AK-47 assault rifle and shot dead five more sailors. He then took two hostages, whom he later killed. He barricaded himself in the torpedo room, and for 20 hours, repeatedly threatened to set a fire to detonate the torpedoes. While Vepr had no nuclear weapons and her reactor was shut down, the detonation of her torpedoes while she was tied up at the dock would have ruptured her reactor, creating what the regional director of the Federal Security Service (FSB), Vladimir Prikhodko described as "a nuclear catastrophe ... a second Chernobyl."
