The 17th Weapons Squadron is a United States Air Force unit, assigned to the USAF Weapons School at Nellis Air Force Base, Nevada. The squadron traces its lineage to the United States Army Air Service's 17th and 147th Aero Squadrons, both of which were active during World War I. The 147th was redesignated the 17th Pursuit Squadron in the post-war Air Service and later consolidated with the 17th Aero Squadron in 1936 to preserve the history of both pursuit units. The 17th Aero Squadron was activated in August 1917 and earned 13 campaign streamers in France flying the Sopwith Camel. The 147th Aero Squadron was organized in November 1917 and flew the Nieuport 28 and SPAD S.XIII fighters, earning eight streamers.
