Mitsubishi G4M "Betty"

"The Flying Lighter" — long range bought with no protection at all.

§ Summary

The G4M was designed for the vast distances of the Pacific, and its range was extraordinary. But that range was achieved by packing the wings with unprotected fuel — a single incendiary round would light them up. Its crews called it the "Hamaki" (cigar); Allied pilots called it "the one-shot lighter."

§ Service History

01Sank the British battleship HMS Prince of Wales and the battlecruiser HMS Repulse off Malaya on 10 December 1941 — the first time capital ships at sea had been sunk purely by aircraft attack. A turning point in naval warfare.

02Heavily engaged across the Pacific, especially in the Solomons campaign. On 18 April 1943, a G4M carrying Admiral Isoroku Yamamoto was intercepted and shot down by P-38 Lightnings in Operation Vengeance, a direct result of broken Japanese codes.

03Late-war G4M2e variants served as motherships for the desperate Yokosuka MXY-7 Ohka — the rocket-propelled, piloted flying bomb used in kamikaze attacks. The G4M was also the aircraft used to fly Japanese surrender delegations in 1945.
