The Hawker Hunter, which came into service in the mid-50s, was born from a specific Royal Air Force requirement, in the late 40s, highlighted the need for a jet fighter aircraft similar, in terms of performance, to the American F-86 Sabre & the Soviet Mi G-15. Featured by a strong structure, it was able to reach, thanks to its Rolls-Royce Avon engine, 1, 150 Km/h. Heavily armed with 4 30 mm. cannons, the Hunter reached the full maturity of the project only with the version F.6 with a better engine performance, reliability & flight autonomy. Later on FGA.9 version, dedicated to ground attack duties, was introduced & featured with four pylons to carry bombs, rockets & additional fuel tanks. The Hawker Hunter was also a commercial success & was used by the air forces of many countries.
