Retaining the wings and horizontal tail surfaces of the
I.A.R.12, the I.A.R.13, which made its debut in 1933,
achieved an aerodynamically cleaner fuselage by replacing
the W-configuration Lorraine engine of the
earlier prototype with a Vee-twelve type Hispano-Suiza 12Mc of 500hp. The I.A.R.13 was of similar construction
to preceding Carafoli-designed fighters, with
a wooden fuselage and wing of mixed construction,
and proved under test to have a very good performance.
However, the Romanian Aeronautica Militara preferred
the gulled shoulder-wing arrangement of the
P.Z.L. P.11 fighter to the low-wing configuration of the
I.A.R. fighters. In 1934, the Polish aircraft was selected
for the re-equipment of its fighter element, with licence
manufacture to be undertaken by I.A.R. Nevertheless,
the Romanian company was to persist with its own line
of fighter development.
