The 134th Observation Squadron was constituted in the National Guard in 1921 as the 134th Squadron (Observation) and assigned to the III Corps.
Placed on the deferred list on 2 July 1923 and transferred to the Organized Reserve as a Deferred National Guard unit.
Concurrently re-designated as the 553rd Observation Squadron and assigned to the 328th Observation Group (III Corps).
Withdrawn from allotment to the National Guard and the Third Corps Area on 17 September 1927 and demobilized.

Although this unit trained near the current Burlington International Airport, and shares the same numerical designation as the 134th Fighter Squadron, the unit was never consolidated with the 134th Fighter Squadron by the Air Force Historical Research Agency or the National Guard Bureau and does not share any lineage or history with the current Vermont Air National Guard.
