While many torpedo bombers were single-engine aircraft, some multi-engined aircraft have also been used as torpedo bombers, with the Mitsubishi G3M "Nell" and Mitsubishi G4M "Betty" being used in the sinking of HMS "Prince of Wales" and "Repulse". Other twin-engine or three-engined aircraft designed or used as torpedo bombers include the Mitsubishi Ki-67, the Savoia-Marchetti SM.79 "Sparviero", the CANT Z.1007, the Bristol Beaufort and Bristol Beaufighter ("Torbeau"), the Junkers Ju 88, the Heinkel He 111, the B-25 Mitchell and many others.
