The 77th (Squadron A) was reconstituted and consolidated with the 77th Observation squadron in 1936. The 77th Observations Squadron was constituted on 8 May 1929 and then was redesignated as the 77th Pursuit Squadron on 8 May 1929 but not activated. On 15 November the 77th Pursuit Squadron activated as the first tactical unit assigned to the 20th Pursuit Group at Mather Field, California, with an officer strength of four. Basically in 1936 the 77th Pursuit Squadron had its history merged with that of the 77 Aero Squadron (Squadron A).
