There's a covert helicopter hiding in the clouds that can detect, identify and locate vehicles and people at distances up to 10km.
It's called Luna - an airborne, unmanned, short-range reconnaissance system for the Armoured Reconnaissance Corps of the German Army.
The Luna helicopter, complete with portable ground control station, has been developed by German company ESG, which is displaying the spy in the sky in Hall 2C/F24.
Company spokesman Roland Ziegler says: "The advantage with the Luna helicopter over other reconnaissance systems is that it can be operated through a variety of speeds up to 100km/h. It is also very flexible in altitude and very quiet."
