i present to you the most sophisticated projet i have ever done with more than a 300 hrs of labor including research.and there is not alot of information about this plane so i went to the airforce museum in cairo to take a closer look and refine the plane even more. this might be the most accurate ha300 model . please idmire it. Most of people know it as the last Messerschmitt because it was the last jet designed by him. The first prototype of the HA-300, powered by a 2,200 kgp Orpheus Mk 703-S-10, first flew on 7 March 1964, and achieved Mach 1.13. Egypt sent two Egyptian pilots to India in 1964 to prepare for the HA-300 flight development. It was followed by a second Orpheus-powered prototype which first flew on 22 July 1965. The third and last prototype was fitted with the Egyptian E-300 engine, which it was hoped would make it capable of attaining 12,000 m and Mach 2.0 within 2.5 min of takeoff. This prototype was flight-tested at least one time when it achieved speed 2.1 Mach with the Egyptian Brandner E-300 engine.A total of 135 million Egyptian pounds was spent on the development,headed by Messerschmitt, moved to Helwan, Egypt, to continue their work on the HA-300, which now stood for HA-300. Ferdinand Brandner, an Austrian jet engine expert, was also invited to develop a turbojet for the new fighter. Egypt aimed to produce a lightweight supersonic, single-seat fighter which could join the Egyptian Air Force as an interceptor.After the Six-Day War defeat, Egypt needed most of its military budget for acquiring new tanks, artillery, TU-16 heavy bombers, aircraft and air defenses and so, due to this and the Soviet pressure to stop the program to prevent the HA-300 to win the challenge against the Soviet Mig-21, the high availability of Russian fighters with Soviet pilots, the special discounts for arms sales to Egypt, the Egyptian government terminated the project finally in May 1969.General characteristicsCrew: 1 (pilot)Length: 12.4 m (40 ft 8 in)Wingspan: 5.84 m (19 ft 2 in)Height: 3.15 m (10 ft 4 in)Wing area: 16.7 m2 (180 sq ft)Empty weight: 3,200 kg (7,055 lb)Gross weight: 5,443 kg (12,000 lb)PerformanceMaximum speed: Mach 2.1 with Brandner E-300 engine , 1.7 Bristol Orpheus engine.Combat range: 1,400 km (870 mi; 756 nmi)Service ceiling: 18,000 m (59,055 ft)Rate of climb: 203 m/s (40,000 ft/min)ArmamentGuns: Two 30mm Hispano or four 23mm Nudelman-Rikhter NR-23 cannonMissiles: Four infrared homing air-to-air missiles
