When did the homing torpedo become the main anti-submarine weapon?
Short answerThe transition began in the 1960s and became more firmly established in the 1970s.
NotesThe transition occurred across a broad period rather than in one introduction year. Homing torpedoes began taking the main anti-submarine role in the 1960s, with the change more fully established in the 1970s. A weapon's initial adoption can precede the point when it dominates fleet practice by many years.
