433rd Weapons Squadron

Established by Fifth Air Force in Australia in May 1943 specifically to accommodate very long range Lockheed P-38J Lightnings at Amberley Airfield in Queensland, Australia. The 433rd was specifically trained to provide long-range escort for bombers during daylight raids on Japanese airfields and strongholds in the Netherlands East Indies and the Bismarck Archipelago.

Engaged in combat operations, providing escort for B-25 Mitchell medium bombers that were engaged in strafing attacks on airdromes at Wewak but also destroyed a number of the enemy fighter planes that attacked the formation. Also intercepted and destroyed many Japanese aircraft which were sent against American shipping in Oro Bay on 15 and 17 October 1943. Covered landings in New Guinea, New Britain, and the Schouten Islands. After moving to Biak in July 1944, the squadron flew escort missions and fighter sweeps to the southern Philippines, Celebes, Halmahera, and Borneo.

The squadron flew many missions to support ground forces on Luzon during the first part of 1945. Also flew escort missions to Southeast China and attacked railways on Formosa.

After active combat ended, on 22 September 1945, the squadron moved to Seoul Airfield, Korea for occupation duty as part of the 308th Bomb Wing, assigned to the 315th Air Division of Far East Air Forces. The unit moved to Kimpo Airfield, on 7 January 1946 where it converted to the very long-range P-51H Mustang. The squadron was reassigned to Nagoya Airfield, Japan in March 1947 and later moved to Itazuke Airfield, Japan in August 1948. It became a subordinate unit of 475th Fighter Wing on 10 August.

Beginning in May 1967, it was re-equipped with new F-4D aircraft. This gave the unit the distinction of being the first in Southeast Asia to be operationally equipped with improved Phantom II. In May 1968, the squadron began combat-testing the first laser-guided bombs (LGBs), the BOLT-117 and the Paveway.[3]

During its final years of combat, used F-4Ds for fast-forward air control, interdiction, escort, armed reconnaissance, and other special missions.

Upon completing the course, graduates return to their home stations, taking the latest tactics, techniques and procedures for air-to-air and air-to-ground combat to their respective units. During the course, students receive an average of 400 hours of graduate-level academics and participate in demanding combat training missions. The climax of the course is the mission employment phase, a two-week staged battle over the Nevada Test and Training Range.
