Mitsubishi G4M Type 1 Attack Bomber / Betty Family

The Mitsubishi G4M was Japan's long-range, twin-engine naval attack-bomber family of the Pacific War, optimized for range and payload over rugged protection. Allied reporting called it Betty; the aircraft carried out maritime strike and long-range land-attack missions, and transport conversions later extended the same airframe into liaison and special-purpose service. Its combat reach and vulnerability became a defining contrast in wartime aircraft design.
