Why did the U.S. Navy often scout with dive bombers while the Royal Navy used Swordfish torpedo aircraft?
Short answerRoyal Navy doctrine centered the torpedo, so its TSR aircraft combined torpedo attack with spotting and reconnaissance rather than separating those functions into a dive-bomber force.
NotesBritish practice reflected a doctrinal difference rather than an aircraft-quality ranking. The Royal Navy placed exceptional weight on the torpedo because a hole below the waterline could sink a ship, while a bomb hole admitting air might not. Its torpedo-spotter-reconnaissance category joined the primary attack weapon to the tasks that found targets and supported fleet gunfire. The Swordfish became a general-purpose aircraft because those missions were designed into the same concept. This explains why British scouting practice differed from the U.S. Navy's greater use of dive bombers in the role.
