IAR 99 Soim

The IAR 99 Șoim is an advanced trainer and light attack aircraft capable of performing close air support and reconnaissance missions.

The aircraft is of semi-monocoque design, with tapered wings and a swept-back tail unit.

A large blade-type antenna installed beneath the nose on the port side of the fuselage gives the IAR 99 trainer a distinctive appearance.


IAR 99 “Standard”

Initial variant designed as a lead-in trainer for the IAR-93.

IAR 109 “Swift”

In 1992 an upgrade program was started in partnership with IAI Lahav of Israel, for both Romanian Air Force use and export.

Aircraft number 7003 was equipped with HOTAS (Hands On Throttle and Stick) controls in both cockpits, a wide-angle HUD (Head-Up Display) with Up Front Control Panel in the front cockpit, two 3 inch displays in both cockpits, a ring laser gyro Inertial Navigation System (INS), as well as the integration of both Eastern and Western weapon systems on the aircraft.

The aircraft was displayed at the 1993 Paris Air Show and flew at Asian Aerospace in 1994.

A prospective sale of 10 aircraft to Botswana was blocked in parliament, ending the collaboration with IAI.

The aircraft was converted back to Standard configuration and delivered to the centre for flight research and testing (CCIZ).

As late as 2009 it still retained it’s “Swift” styled paint scheme and logo.
