Argentine Flying Fortress: The Story of the FMA IA-58 Pucar

In the 1960's guerrillas were operating in almost all Latin American countries, as well as in Africa and Asia, and the need of specialized weapons to fight them arose. The Argentine Air Force, seeing this threat grow, asked the FMA factory to produce a counterinsurgency airplane to equip the force, but also to offer on the international market. After several proposals were analysed, a final product emerged, called the IA-58 Pucar , a robust twin turboprop aircraft with heavy internal weapons, planned to operate from unprepared airstrips on very hard conditions. The plane entered service with the Argentine Air Force in 1975 and more than 100 were produced over the years, with several versions being developed or proposed. It was purchased by Uruguay, Colombia and Sri Lanka, the type gained world notoriety when they took part on the 1982 South Atlantic war, but also had combat experience in Colombia and Sri Lanka, and was tested by the Royal Air Force. Now, with the original version already retired, the Argentine Air Force plans to convert them into the Pucar F nix version, with new engines and avionics, with new missions too, like intelligence, surveillance and reconnaissance. While some aspects of its story were described in many publications, most of it has never been told until now, including many unknown proposed versions and details of its operational record, both in Argentina and in the other countries that operated the plane.
