The Terrifying Reason Why This Dead Russian Nuclear Submarine Is a Ticking Time Bomb

While K-27 ultimately turned out to be a disaster, her lead-bismuth technology would eventually be used onboard the Soviet Union’s later Project 705 Lira (Alfa-class) boats. Those vessels—though incredibly fast and deep diving—were eventually withdrawn from Russian service due to the sheer expense of maintaining them. Meanwhile, the United States made one very brief foray into the world of liquid-metal cooled reactors with the USS Seawolf (SSN-575) in the 1950s, but U.S. Navy quickly abandoned the troublesome sodium-cooled powerplant in favor of pressurized water reactors.
