The 643d Bombardment Squadron is an inactive United States Army Air Forces unit. After training with Douglas A-20 Havocs in the United States the squadron deployed to the European Theater of World War II, where it engaged in combat until the Surrender of Germany. It was last assigned to the 409th Bombardment Group at Westover Field, Massachusetts, where it was inactivated on 7 November 1945. ==History== The 643d Bombardment Squadron was activated in June 1943 at Will Rogers Field, Oklahoma〔 as one of the four original squadrons of the 409th Bombardment Group.〔Maurer, ''Combat Units'', pp. 294–295〕 The squadron trained under Third Air Force in Oklahoma, Texas and Louisiana with A-20 Havoc light bombardment aircraft.〔 The squadron deployed to the European Theater of Operations (ETO) in March 1944, where it became part of IX Bomber Command of Ninth Air Force.〔 The 643d initially flew sweeps over Occupied France from its base in England, attacking coastal defenses, V-1 flying bomb and V-2 rocket sites, airfields, and other targets in France in preparation for Operation Overlord, the invasion of Normandy. After D-Day, the squadron supported ground forces during the Battle of Normandy by hitting gun batteries, rail lines, bridges, communications, and other objectives. During July 1944, it aided the Allied offensive at Caen and the breakthrough at Saint-Lô with attacks on enemy troops, flak positions, fortified villages, and supply dumps.〔 The squadron moved to Advanced Landing Grounds in France in September 1944, providing Third Army with close air support in its advance toward Germany through November.〔 In December, the squadron converted to Douglas A-26 Invaders. It then participated in the Battle of the Bulge by attacking lines of communications and logistics. The squadron continued combat operations until May, flying its last combat mission against an ammunition dump in Czechoslovakia on 3 May.〔 The unit returned to the United States and initially was assigned to Seymour Johnson Field, North Carolina where it prepared to deploy to the Pacific Theater of Operations (PTO) for operations against the Japanese Home Islands. The deployment to the Pacific Theater was cancelled with the Surrender of Japan in August. The 643d was inactivated at Westover Field, Massachusetts in early November.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「643d Bombardment Squadron」の詳細全文を読む スポンサード リンク
