Mitsubishi G4M

The Mitsubishi G4M  was was the main twin-engined, land-based bomber used by the Imperial Japanese Navy Air Service in World War II. The Allies gave the G4M the identification name of Betty. Using its long range and high speed, the G4M could appear from any direction, and then be gone before many fighters could intercept them. The 20 mm cannon in the tail turret was much heavier armament than commonly installed in bombers, making dead astern attacks very dangerous.
