The I.A.R.15 flew for the first time late in 1933, powered by a 600hp Gnome-Rhone 9Krse nine cylinder radial and carring an armament of two 7.7mm Vickers machine guns. 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 centre section with fabric covering for the outer panels. A series of five I.A.R.15s was ordered for the Aeronautica Militara, these differing from the prototype primarily in having three-bladed metal propellers in place of the two-bladed wooden unit. The I.A.R.15 established a national altitude record of 11631m in 1936. It was considered inferior to the P.Z.L. P.11 in manoeuvrability, and no further examples were ordered.
