There was a serious accident on board K-3 on 8 September 1967. The submarine was performing a patrol mission in the Mediterranean Sea and a hydraulic system fire occurred in compartment one on the 56th day of the cruise at a depth of 49&nbsp;m during the return home. This occurred north-east of the Faeroes and 39 sailors died due to [[carbon monoxide]] poisoning (boatswain Lunya was the only person in the central station who didn't black out. He surfaced the submarine and rescued the commander and second-in-command who organized damage control). The submarine reached base successfully. K-3 performed 14 long range cruises and passed 128,443 miles over 30 years (1958–1988).
