The squadron was assigned as an Army Observation Squadron, performing long-range, strategic reconnaissance over the entire length of the United States First Army sector of the Western Front in France. After the 1918 Armistice with Germany, the squadron was assigned to the United States Third Army as part of the Occupation of the Rhineland in Germany. It returned to the United States in June 1919 and became part of the permanent United States Army Air Service in 1921, being re-designated as the 91st Squadron.
The current United States Air Force unit which holds its lineage and history is the 91st Cyberspace Operations Squadron, assigned to the 67th Cyberspace Wing, Kelly Field Annex, Lackland Air Force Base, Texas.
