HAI E1-79 "Pegasus" is an Unmanned Aircraft System (UAS) of Greek origin, developed and produced by Hellenic Aerospace Industry (Sea ). Reserved for intelligence-surveillance-reconnaissance (ISR) missions on the battlefield, the aircraft has been in limited production since entering service. Development of the Pegasus was carried out jointly by KETA (Hellenic Air Force Research and Development Centre) and HAI, and began in 1979, although the first flight in prototype form did not take place until 1982.
After that, the product had to wait a long time to see the official launch of the service - which happened in 1992.
The Pegasus has a dual-arm thruster propeller arrangement and a flat-sided fuselage and high-mounted wings as per UAS standard. The arms emanate from the trailing edge of each main aircraft, are defined at the rear by vertical tails, and are connected by a common horizontal plane. The landing gear is a tricycle arrangement that remains in place during flight and is driven by wheels. Above the hull is a protruding piece that houses a disc-shaped fitting.
A trainable turret, housing sensors and camera equipment can be seen under the fuselage.
Dimensions include a barrel length of 6.9 feet and a wingspan of 16.4 feet, making it relatively compact. With its traditional propulsion scheme (propeller drive in a thrust arrangement), the UAS can reach speeds of 100 miles per hour.
Using internal fuel, the aircraft has an endurance of 3.5 hours.
"Pegasus II" is a larger, heavier, more advanced evolution of the original Pegasus platform with improved mission capabilities. The entry first appeared in 2005, and the total production to date (2020) has been similarly limited. The length increases to 14.1 feet, while the wingspan reaches 20.34 feet, while it can stay in the air for about 15 hours.
It continues to have the ISR function as its primary role.
