The Mitsubishi G4M, nicknamed "Betty" by the Allied Intelligence Service, was the first heavy bomber in use in the Imperial Japanese Navy.

It was first used in south-east China in Spring 1941. Over Guadalcanal in 1942, the G4M earned the nickname "Hamaki" (flying cigar), because it often started burning as soon as it was hit by enemy fire. Later versions had more protection, but the Betty always stayed vulnerable to American fighters, even with 20 mm defensive guns.

On April 18, 1943, Admiral Yamamoto was on an inspection tour of Japanese Navy bases when he was shot down and killed in a G4M1 Model 12 by a flight of P-38s Lightning.

One of the last missions of the G4M was the most historically important: a G4M was used as a transport for the Japanese delegation in charge of signing the peace agreements, that marked the end of World War II.
