Tunisian UAVs

Short range UAV demonstrator Nasnas
The TAT Nasnas is an unmanned aerial vehicle (UAV). Tunisia was the first Arab country to develop this industry in 1997. In 2003, it was joined by the United Arab Emirates. The UAVs are constructed and designed in Tunisia. They are produced by the company Tunisia Aero Technologies (TAT). The flight of the first Tunisian drone, "TAT Aoussou", took place in October 1997. It served primarily as an aerial target for anti-aircraft units. It was designed and built in eight months. The first flight of the prototype "TAT Nasnas" (or anasnas) took place in August 1998. It was designed and built in six months.

TAT Jebelassa 650
The Jebelassa 650 (means in Arabic: Mountain Watch) has evolved subsequently to give birth to a new version of the Smaller Nasnas which is "stronger and more polished".


 * Wing Span: 6m50
 * area of 3.80 m2 wing
 * length 3m80
 * height 1.30m
 * weight, 158 kg dry, maximum takeoff weight 270 kg
 * payload of 55 30 kg
 * cruising speed 170 km / h, Loiter Speed: 120 km/h
 * altitude of 5,200 m.
 * 24h autonomy flight
 * engine: 38 hp diesel/jet A1/injection modified engine.*Mission Radius: 200 km. Can be extended to 800 km when using Radio Relays.

The first flight of the prototype Jebelassa took place in 2004. It has a larger radius of action the UAV can carry more payloads and missions.
