The first of only three JF-105Bs ever built, prototypes for the projected RF-105B reconnaisance version that was cancelled in favour of the already existing RF-101. The trio was still completed with modified noses but without cameras. Retired in 1966, this is the only surviving one as JF-2 crashed and JF-3 was scrapped. Preserved at Lackland already in the 1970s in fake colours, later restored to this accurate test livery.

Broadly equivalent to the de Havilland Chipmunk, the Aero 3 first flew in 1956 and from 1958 a total of 110 were built for the Yugoslav AF as primary trainers. They could also be employed in the army co-operation role and served until the mid-1970s when several found their way onto the civil market.

On display next to the museum building.

Formerly designated RF-105B.
