A nuclear torpedo is a torpedo armed with a nuclear warhead. The idea behind the nuclear warheads in a torpedo was to create a much bigger explosive blast. Later analysis suggested that smaller, more accurate, and faster torpedoes were more efficient and effective.[1]
During the Cold War, nuclear torpedoes replaced some conventionally armed torpedoes on submarines of both the Soviet and American navies.
The USSR developed the T15, the T5 and the ASB-30. The only nuclear warhead torpedo used by the United States was the Mark 45 torpedo.[2] The Soviet Union widely deployed T5 nuclear torpedoes in 1958 and the U.S. deployed its Mark 45 torpedo in 1963.[3]: 28 In 2015, there were rumors that Russia was developing a new nuclear torpedo, the Status-6.
