Continuing with extracts and commentary from the book: "K-19, The Widowmaker" by the American author Peter Huchthausen.
The topic the submarine either sinking or severely damaged, while in port, moored, not sailing. This phenomenon more common than we might think. NOR was the submarine fleet of the Soviet Union immune to such disaster.
1. 1962 11 January.
"Northern Fleet Project 641, Tango-class, B-37, diesel submarine. A torpedo exploded while the submarine was at home port, and it sank."
This sub rather a Foxtrot class?
"Northern Fleet November-class K-11. Suffered a reactor accident in Severodvinsk . . . the reactor
suffered an uncontrolled power surge while charging the plant."
3. 1968 25 August.
"Northern Fleet Yankee II-class SSBN, K-140 suffered an uncontrolled reactor power surge while in port."
4. 1970 Late.
"Alpha-class [Alfa] submarine suffered a reactor meltdown."
This actually was the K-62 and the event occurred in 1972?
5. 30 November 1980.
"Northern Fleet prototype Project 661, Papa-class, K-162, nuclear- powered submarine suffered an uncontrolled reactor power surge in the Severodvinsk shipyard."
Also referred to as the K-222
6. 10 August 1985.
"Pacific Fleet Project 675, Echo II-class SSGN, K-431, while refueling in Chazhma Bay, the fuel rod assembly was accidentally lifted. In the ensuing explosion and fire, ten men were vaporized and the reactor cover blown off."
7. 1991 20 January.
"Pacific Fleet Project 641, Foxtrot-class diesel attack submarine, sank while docked at Vladivostok."
In the old Soviet Union ships did not sink, automobiles did not collide, trains did not run off the track and planes did not fall out of the sky!!
