 | | Military submarines are generally divided into attack submarines, designed to operate against enemy ships, including other submarines, in a hunter-killer role, or strategic ballistic-missile submarines, designed to launch attacks on land-based targets from a position of stealth, also known as "boomers" in the United States Navy or "bombers" in the Royal Navy. |
 | | Submarines designed for the purpose of attacking merchant ships or other warships are known as "fast attacks", "hunter-killers", "fast boats", or "fleet submarines" (which terms are not synonyms; each is a different design for a different mission). |
 | | Where Japan had the finest submarine torpedoes of the war, the USN had perhaps the worst, the Mark 14 steam torpedo, with a Mk 6 magnetic influence exploder and a Mk 5 contact exploder, neither of which was reliable. |
