Non-US Battlefield UAVs - EADS Orka, Scorpio, Surveyor

EADS Orka, Scorpio, Surveyor

• The European Aerospace & Defense Systems (EADS) company is currently promoting a number of UAVs. One, the "Orka", is a UAV helicopter with an airframe length of 6.2 meters (20,3 feet) and a weight of about 700 kilograms (1543 pounds) for use by the army and on naval vessels. It is currently favoured as the likely replacement for the larger and heavier SEAMOS helicopter UAV that was abandoned by the Germans.

The Orka is derived from a light helicopter the Cabri built by Hélicoptères Guimbal of France. It has a conventional helicopter configuration, with a three-bladed main rotor with a diameter of 7.2 meters (23.6 feet), an enclosed "fenestron" tail rotor favoured by the French, and landing skips. There is a sensor turret under the nose and an antenna or sensor drum under the belly between the landing skids. The production Orka is expected to have an endurance of 8 hours and a payload of 150 kilograms (331 pounds).

• The EADS "Scorpio" is a much smaller battlefield helicopter, focused on special operations. It is also of conventional helicopter configuration, with a two-blade main rotor with Hiller-type stabilization paddles, an exposed two-blade tail rotor, and landing skids. A sensor turret may be fitted between the landing skids. There are several variants in the Scorpio line:

• The 13 kilogram (29 pound) "Scorpio-6" flies at 35 km/h (22 mph) and has an endurance of an hour.

• The 40 kilogram (88 pound) "Scorpio-30" flies at 50 km/h (31 mph) and has an endurance of two hours.

• The EADS "Surveyor" is still in preliminary investigation phase. It will be a fixed-wing, jet-powered UAV and is being positioned as a replacement for the CL-289. EADS is currently working on a demonstrator, the "Carapas", modified from an Italian Mirach 100 drone. The production Surveyor would be a stealthy machine with a top speed of 850 km/h (530 mph), an endurance of up to three hours, and capable of carrying a sophisticated sensor payload, including SIGINT gear. It would also be able to carry external loads, such as air-dropped sensors or light munitions.
