History

Training in the United States

The 673d Bombardment Squadron was activated in the spring of 1943 at Will Rogers Field, Oklahoma as one of the original squadrons of the 417th Bombardment Group The squadron drew its initial cadre from the 46th and 416th Bombardment Groups. Once assigned, the 673d's key personnel travelled to Orlando Army Air Base in mid-April where they received combat training from the Army Air Forces School of Applied Tactics.

The first Douglas A-20 Havocs arrived to equip the squadron in mid-May along with some DB-7 export models of the Havoc. Initial training of the 673d was conducted by the 46th Bombardment Group, the Operational Training Unit at Will Rogers Field. The unit then moved to DeRidder Army Air Base, Louisiana for advanced training. From August to September the 673d operated with the II Tactical Air Division, giving low level support to ground units on maneuvers. Once training was completed The squadron departed the San Francisco Port of Embarkation by ship on New Year's Day 1944.

Combat in the Southwest Pacific

The squadron arrived in New Guinea in late January 1944, where it became part of Fifth Air Force. It began combat in March, operating in support of ground forces on New Guinea and striking airfields, bridges, personnel concentrations, installations, and shipping in the area. The 673d participated with other Fifth Air Force units in attacks on shipping and enemy airstrips near Hollandia on 16 April that resulted in the destruction of 298 enemy planes.

The unit operated from Noemfoor from September to December 1944, attacking airfields and installations on Ceram, Halmahera, and western New Guinea. Noemfoor operations included attacks on oil installations. The squadron moved to the Philippines in December 1944 at the end of the New Guinea campaign. The unit's ground crews left Noemfoor by ship while the aircrew flew to the Philippines once the advance party had prepared McGuire Field for use in late December. While en route, the convoy transporting the ground echelon endured two Japanese air attacks.

The squadron received a Distinguished Unit Citation for attacking Japanese convoys at Lingayen between 30 December 1944 and 2 January 1945, an action that not only impaired enemy shipping and supply strength, but also helped to clear the way for the American invasion of Luzon. During these attacks the 417th group sank 36,000 tons of shipping including a freighter, a destroyer escort and several transports.

Until June 1945 the 673d supported ground forces and continued to attack enemy airfields, transportation, and installations on Luzon, Cebu, Negros, and Mindanao. The squadron flew its last missions in July, dropping propaganda leaflets to Japanese troops on Luzon. After the Philippines were secured, the group turned its attention to Japanese targets on Formosa in early 1945. It moved to Okinawa in August 1945 and to Itami Air Base, Japan in November, where it was inactivated on 15 November 1945.
