Vestel Karayel. The Vestel Karayel is a surveillance, reconnaissance and later combat unmanned aerial vehicle system developed by Vestel Savunma later the company renamed as Lentatek. The drone is currently operated by Turkish Armed Forces and the Armed Forces of Saudi Arabia.

Design
The Karayel is designed and manufactured in accordance with NATO ‘Airworthiness’ standard; STANAG 4671. The Karayel system has novel triple redundant distributed avionics architecture which ensures protection against all kinds of uncontrolled crash. With this feature, systematic fault safety used only in manned aviation around the world until now, has been carried to an unmanned aerial vehicle for the first time with the Karayel. The aerial vehicle has the ability to protect against lightning thanks to the aluminum network grid on its composite structure. A de-Icing system automatically detects icing conditions allows operations in cold climates. The Karayel, which is an aerial reconnaissance and surveillance platform, can perform target marking, lighting and ammunition direction by its laser sensors and day/night target detection and identification by its camera system which it carries as payload.
