MBLE Épervier
The MBLE Épervier () was a 1970s Belgian battlefield reconnaissance system which included an X-5 air vehicle, a launcher and a drone control centre. It served with the Belgian Army until 1999. Design and development. Originally the Épervier system was designed to meet a NATO requirement and in July 1969 the Belgian Government decided to fund the development programme, a cooperation contract with Manufacture Belge De Lampes Et De Matériel Electronique (MBLE) was signed in early 1971. Early prototypes of the drone (designated X-1 to X-4) were flown to prove the concept and at the end of the 1972  in to 1973 the system underwent an operational evaluation, it proved an ability to photograph a target up to 70 km (43 miles) away in either guided or programmed mode. The X-5 air vehicle is an unmanned monoplane drone powered by a Lucas TJ 125 turbojet, and built under contract by Fairey SA. It has a truncated delta wing with endplate fins and a central fin. The X-5 can carry 70mm day or night cameras and infra-red line-scanning equipment which can transmit real-time data. The launcher is a short orientable ramp, the drone is recovered by  parachute. The Drone Control Centre has all the equipment to for guiding and tracking the air vehicle. The system also has a mobile photographic processing and interpretation unit. Operational history. Following further evaluation and testing the Épervier entered service with the Belgian Army in 1977 and served until 1999.
