The Allies gave the G4M the identification name of Betty. The G4M was designed for long range and high-speed at the time of its introduction. Consequently, weight saving measures were incorporated into the design, such as dispensing with self sealing fuel tanks, which caused Allied fighter pilots to give it the derisive nicknames "one-shot lighter", "flying Zippo" and "flying cigar". Similarly, pilots of the Imperial Japanese Navy called the G4M the "Type One Lighter" and "Hamaki" ("Cigar"). This was due to the fact that on many occasions, it was used for low-altitude torpedo attacks where its performance advantages were negated.
