After World War II, battleships ended their role as the mainstay of naval forces.
In strict naval terminology, 戦艦 refers specifically to battleships (heavily armored capital ships), not warships in general. However, in casual usage and fiction, it is sometimes used loosely for any large warship. The anime "Space Battleship Yamato" (宇宙戦艦ヤマト) is a cultural touchstone that keeps the word familiar. Related: 軍艦 (warship — general term for any military vessel), 空母 (aircraft carrier), 駆逐艦 (destroyer), 巡洋艦 (cruiser).
