Mitsubishi G4M “Betty” bomber under fire near Truk Lagoon, February 1944. Photographed by Lt. Cdr. William Janeshek from a U.S. Navy PB4Y Liberator during Operation Hailstone (17–18 February 1944), the massive U.S. carrier and bomber assault that shattered Japan’s key forward base in the Caroline Islands.
Bullet splashes walk across the sea as the Betty, trailing smoke from its starboard engine, makes a desperate low-level run. Moments later it struck the water and exploded. The G4M had earned fame early in the war—sinking Prince of Wales and Repulse in December 1941—but its lack of armor and self-sealing fuel tanks gave it the grim reputation of a “flying cigar.” By 1944, in the skies over Truk, it was hopelessly outclassed.
Operation Hailstone cost Japan over 250 aircraft and more than 40 ships, neutralizing Truk and marking a decisive shift in the Pacific War.
