About This Unit
" During World War II, the 90th, a Bombardment Squadron, operated in the South Pacific, flying A-20 Havoc and B-25 Mitchell aircraft. Their main mission involved highly-dangerous skip bombings. In an effort to improve the effectiveness and protection of the 3d Bombardment Group's pilots, Major Paul 'Pappy' Gunn, 3d Bombardment Group engineering officer, devised a modification of the B-25C. The modification replaced the forward bombardier with four forwards firing .50 caliber machine guns, supplemented with two twin .50 caliber gun packages side mounted on the fuselage. The lower turret was discarded. The A-20s received similar modifications. The modified aircraft were first employed by the 90th and proved exceptionally effective, receiving the nickname 'commerce destroyers.' During the Battle of the Bismarck Sea, every aircraft in the 90th scored a hit on the Japanese convoy of 18 ships. It was the first sea-level attack by B-25 strafers in World War II and demonstrated that this tactic was extremely effective. The squadron also participated in the raids on Wewak, New Guinea, which were preemptive strikes that virtually ended the threat of enemy offensive air capabilities. "
