Tá Mitsubishi G4M byl dvoumotorový pozemní střední bombardér dříve vyráběný společností Mitsubishi Aircraft Company, která byla součástí Mitsubishi Heavy Industries a v letech 1940 až 1945 byl provozován japonským císařským námořnictvem. Jeho oficiální označení je Mitsubishi Navy Type 1 útočný bombardér (一式陸上攻撃機, 一式陸攻 Ichishiki rikujō kōgeki ki, Isshikirikukō) a piloti japonského námořnictva ho běžně označovali jako Hamaki (葉巻, "doutník", osvětlený. "listový válec") kvůli válcovitýmu tvaru trupu. Spojenecké zpravodajské jméno bylo "Betty".

General Characteristics

The Mitsubishi G4M (Allied reporting name: Betty) was a twin-engine land-based attack bomber used by the Imperial Japanese Navy Air Service during World War II. Designed by Kiro Honjo, its development prioritized extremely long range to meet the vast distances of the Pacific theatre, a requirement that necessitated large fuel tanks and a lightweight airframe. This design decision famously led to a lack of protective armor and self-sealing fuel tanks in the early models, making the aircraft highly vulnerable to enemy fire—earning it the derisive Allied nickname, “The Flying Lighter,” and the Japanese nickname, “Hamaki” (Cigar) for its cylindrical fuselage shape. Despite its fragility, the G4M was responsible for the crucial sinking of the British capital ships HMS Prince of Wales and HMS Repulse in 1941.

Powerplant and Performance

Engine: 2 x Mitsubishi MK4A Kasei 11 14-cylinder air-cooled radial piston engines (G4M1).
Power Output (Kasei 11): 1,140 kW (1,530 hp) for takeoff.
Maximum Speed (G4M1): 428 km/h (266 mph) at 4,200 m (13,780 ft).
Maximum Speed (G4M2): Approx. 437 km/h (271 mph) at altitude.
Cruise Speed: Approx. 315 km/h (196 mph).

Maximum Range (G4M1 – Ferry): Up to 5,040 km (3,130 mi).
Maximum Range (G4M3 – Reduced Range): 4,330 km (2,690 mi) (due to armor/self-sealing tanks).

Armament and Variants

Defensive Armament (G4M1):
- 1 x 20 mm Type 99 cannon in the tail turret.
- 4 x 7.7 mm Type 92 machine guns (one in the nose, one in the dorsal turret, two in waist positions).
Offensive Load: Carried internally in a bomb bay:
- One 858 kg (1,892 lb) Type 91 aerial torpedo, or
- Up to 1,000 kg (2,205 lb) of bombs (e.g., four 250 kg bombs).
Key Variants:
- G4M1 (Model 11): Initial production model, optimized for range.
- G4M2 (Model 22): Uprated Kasei 21 engines, four-bladed propellers, improved dorsal turret, and larger wings for better high-altitude performance.
- G4M3 (Model 34): Late-war attempt to improve survivability by adding armor and self-sealing fuel tanks, resulting in a significant reduction in fuel capacity and range.
- G4M2e (Model 24J): Modified to carry and launch the MXY7 Ohka piloted rocket missile (suicide bomb).
