On Friday 3 October 1986, while on an otherwise routine Cold War nuclear deterrence patrol in the North Atlantic 680 miles (1,090 km) northeast of Bermuda, the 15-year-old K-219 suffered an explosion and fire in a missile tube. The seal in a missile hatch cover failed, allowing saltwater to leak into the missile tube and react with residue from the missile's liquid fuel.
on 6 October 1986 the K-219 sank to the bottom of the Hatteras Abyssal Plain at a depth of about 6,000 m (18,000 ft). Britanov abandoned ship shortly before the sinking. K-219's full complement of nuclear weapons was lost along with the vessel.
In 1988, the Soviet hydrographic research ship Keldysh positioned itself over the wreck of K-219, and found the submarine sitting upright on the sandy bottom. It had broken in two, aft of the conning tower. Several missile silo hatches had been forced open, and the missiles, along with the nuclear warheads they contained, were gone.
