Switch off JavaScript. Here’s the gist if you don’t want to: “Torpedo Tessies were far more commonly known as torpedo juice, the legendary liquor of World War II servicemen. The name had a literal origin. As of the beginning of World War II, American torpedoes utilized 180-proof ethyl alcohol as fuel for the miniature steam engines that drove them toward their targets. Lacking consistent access to liquor, opportunistic sailors occasionally drained the torpedoes of their alcohol and mixed it with something to cut the strength. The practice existed before the 1940s, albeit quietly, almost an institutional secret. With the rapid expansion of the Navy during the war, torpedo juice exploded in popularity and quickly became public knowledge. As a result, it is inextricably linked to World War II lore.”
