This aircraft was nicknamed the "Flying Cigar" because the fuel tanks were unprotected and easily caught fire. Nevertheless the Mitsubishi G4M was the most famous Japanese bomber of the war and the one produced in the largest quantity. The aircraft saw service throughout the war, from the first day to the last, and was well known by the Allied codename of "Betty". The G4M series was begun late in 1937 at the request of the Japanese Navy, which wanted a land-based bomber that was even better than Mitsubishi's excellent G3M, which was just going into service at that time. High speed and long range were the chief requirements, and the G4M in fact ended up with outstanding range, which literally revolutionized operational concepts in the Pacific. Mass production of the bomber began in 1940, and the first planes came off the assembly line in April 1941. The aircraft made its operational debut in the last phases of the war against China. When Japan and the United States went to war, the G4M had considerable operational experience behind it. Its experience and its long range were responsible for the plane's great success, particularly during the first year of war in the Pacific. The Mitsubishi bomber played a major role in the sinking of the British battleships Prince of Wales and Repulse on December 10, 1941. Soon, however, the Allied air forces learned to exploit its weaknesses (such as insufficient armor and unprotected fuel tanks), and they found themselves no matches for the ever more powerful and plentiful Allied fighters.
