The 89th Attack Squadron (formally the 432nd Attack Squadron), the newest operational squadron at Ellsworth Air Force Base, was reactivated Oct. 1, 2011. The 89th ATKS mission is to remotely employ MQ-9 Reaper aircraft from ground control facilities located at Ellsworth AFB in support of worldwide combatant commander requirements.
The lineage of the 89th dates back to 1917 where it was first organized as the 89th Aero Squadron operating out of Kelly Field, Texas. During World War I, the unit forward deployed to Colombey-les-Belles and Chatillon-su-Seine, France. During this period the unit constructed facilities, maintained aircraft, and trained observers in the "Zone of Advance." The squadron was demobilized on May 19, 1919, reorganized in 1936 as the 89th Observation Squadron, and later re-designated the 89th Reconnaissance Squadron. Additional unit re-designations include: 432nd Bombardment Squadron (1942), 432nd Bomb Squadron (2007), 432nd Attack Squadron (2011) and 89th Attack Squadron (2016).
In 1942, the 89th RS was one of four units assigned to the 17th Bombardment Group, from which several members were selected to fly the infamous April 18, 1942 "Doolittle Raid" on Tokyo, Japan. Additionally, the unit was awarded two Distinguished Unit Citations for action in Europe: on Jan. 13, 1944 for action over Ciampino, Italy and on April 10, 1945 for action over Schweinfurt, Germany. Over the past century the unit has employed several aircraft including the Brequet 14 (1918), B-18 Bolo (1940), B-23 Dragon (1940-1941), B-25 Mitchell (1941-1942), B-26 Marauder (1942-1945), and currently the MQ-9 Reaper.
The 89th ATKS continues this proud heritage of supporting the national security of the United States. The 89th ATKS will provide combatant commanders with actionable precision reconnaissance capabilities for time critical targets, air interdiction, close air support, and strike coordination.
