Remarks by Johan Visschedijk: "Possessing little more than a configurational similarity to preceding single-seat fighters designed by Elie Carafoli, the IAR 15 flew for the first time late in 1933. It was powered by a 600 hp Gnome & Rhône 9Krse nine-cylinder radial and carried an armament of two 0.303 in (7.7 mm) Vickers machine guns.

The structural design followed that of the IAR 14. It had a welded steel-tube fuselage covered by duralumin sheet forward and fabric aft, this being mated with a three-piece wing with two duralumin spars, pine and plywood ribs and duralumin sheet skinning for the center section with fabric covering for the outer panels.

A series of five IAR 15s was ordered for the Rumanian AF, these differing from the prototype primarily in having three-bladed metal propellers in place of the two-bladed wooden unit. The speed capability of the IAR 15 was adjudged excellent and it established a national altitude record of 38,160 ft (11,631 m) in 1935. However, it was considered inferior to the PZL P.11 on the score of maneuverability, and no further examples were ordered."
