The FMA IA 58 Pucará (QuechuaFortress) is an Argentine ground-attack and counter-insurgency (COIN) aircraft manufactured by the Fábrica Militar de Aviones. It is a low-wing twin-turboprop all-metal monoplane with retractable landing gear, capable of operating from unprepared strips when operationally required. The type saw action during the Falklands War and the Sri Lankan Civil War.

Design

In August 1966, Dirección Nacional de Fabricación e Investigación Aeronáutica (DINFIA), the Argentine state aircraft factory began development of the AX-2, a Counter-insurgency (COIN) aircraft to meet a requirement of the Argentine Air Force. The project was promoted by engineer Ricardo Olmedo and became under the guidance of engineer Aníbal Dreidemie, who also designed the IA-52 Guaraní II and the IA-63 Pampa. The chosen layout was a low-wing monoplane powered by two turboprop engines mounted in wing-mounted nacelles and fitted with a T-tail. In order to test the proposed layout, DINFIA first built a full-scale unpowered glider test vehicle, which flew for the first time on 26 December 1967

Variants

Variants

  • AX-02 Delfín: Prototype.
  • AX-04: A torpedo-carrying prototype.
  • IA-58A Pucará: Two-seat counter-insurgencyclose air support, attack aircraft. Main production version. To be retired September 2019.[46]
  • IA-58B Pucará Bravo: Modified two-seat counter-insurgency aircraft, with deeper forward fuselage, allowing the 20 mm Hispano cannon to be replaced by two 30 mm DEFA cannons, and with more advanced avionics. One prototype aircraft converted from IA-58A first flew on 15 May 1979.
  • IA-58C Pucará Charlie: Single-seat version designed to take advantage of lessons learned during the Falklands War, with increased capability in anti-shipping and anti-helicopter missions. Forward cockpit removed, with additional 30 mm DEFA cannon supplementing existing gun armament, and capability to carry Matra R550 Magic air-to-air missiles and Martin Pescador air-to-surface missiles underwing. Increased armour protection fitted, and more advanced EW system suite. Single prototype converted, flying on 30 December 1985, but plans to convert fifteen more for the Argentine Air Force abandoned in 1988 due to lack of funding.
  • IA-58D Pucará Delta: Current program modernisation of existing IA-58A airframes, featuring new avionics systems and 950shp PT6A-62 Pratt & Whitney engines.[52] Also noted as IA-58H. Program restarted in June 2019 with certification planned in July 2019.[46]
  • IA-66: Modification of IA-58A powered by two 1,000-ehp (746-kW) Garrett TPE331-11-601W turboprop engines. Single prototype converted from IA-58A flew in 1980
