The Mitsubishi G4M (long designation: Mitsubishi Navy Type 1 attack bomber: 一式陸上攻撃機, 一式陸攻 Isshiki rikujō kōgeki ki, Isshikirikkō) was the main twin-engine, land-based bomber used by the Imperial Japanese Navy Air Service in World War II. The Allies gave the G4M the reporting name Betty. Japanese Navy pilots called it "葉巻" "hamaki" ("cigar", literally "leaf roll"), due to its cylindrical shape.

The G4M had very good performance, especially range, which was achieved by its structural lightness and an almost total lack of protection for its crew, with no armor plating or self-sealing fuel tanks. These omissions proved to be its weakness when confronted with American fighter aircraft during the Pacific War.[2]

NotesEdit

  1. Serial no. 603 and later had 30 mm (1.2 in) thick natural rubber plates covering the outside bottoms of the wing fuel tanks but this decreased their service range by 10%.
  2. main-pilot, co-pilot, navigator/bombardier/nose gunner, captain/top turret gunner, radio operator/waist gunner, engine mechanic/waist gunner, tail gunner
