644th Bomb Sq

• World War II Origins: The 644th Bombardment Squadron was activated on 1 July 1943 as part of the 410th Bombardment Group, flying the Douglas A-20 Havoc light bomber. • European Theater Operations: The squadron deployed to England in early 1944 and participated in tactical bombing missions in support of the Normandy invasion (D-Day) and subsequent Allied advances. • D-Day Support: On June 6, 1944, the 644th Bomb Sq flew low-level missions against enemy gun positions and transportation targets on the French coast, directly supporting Operation Overlord. • Distinguished Unit Citation: The squadron was awarded a Distinguished Unit Citation for its performance during a mission over France on August 7, 1944, when it attacked heavily defended German positions despite intense anti-aircraft fire. • Battle of the Bulge: The 644th flew critical missions during the Battle of the Bulge, targeting German supply lines, bridges, and troop concentrations to slow the enemy advance in December 1944 and January 1945. • Transition to A-26 Invader: In 1945, the squadron transitioned from the A-20 Havoc to the newer Douglas A-26 Invader, allowing for increased range and bomb load. • Postwar Inactivation: After VE Day, the squadron returned to the United States and was inactivated on November 7, 1945, as part of the general demobilization of the USAAF. • Redesignations: The squadron underwent several redesignations over the years, including as the 644th Bombardment Squadron, Light, and later as 644th Tactical Bombardment Squadron, reflecting changes in aircraft and mission. • Unit Insignia: The squadron’s emblem featured a caricatured bomb-carrying bird, symbolizing speed and striking power, and was proudly displayed on its aircraft during WWII. • Legacy and Honors: The 644th’s legacy is preserved in the lineage of successor Air Force Reserve units, and its history is commemorated in museums and veteran associations dedicated to the 410th Bomb Group.
