In the years following World War I, the Argentine Air Force received various aircraft from France and Italy. In 1922, the "Escuela Militar de Aviación" was temporarily disbanded, resulting in the formation of "Grupo 1 de Aviación" ('Aviation Group One') as an operational unit. Three years later, in 1925, the "Escuela Militar de Aviación" was reopened, and the "Grupo 3 de Observación" ('Observation Group Three') unit was created. Shortly after, "Grupo 1 de Aviación" became known as "Grupo 1 de Observación".
