British troops in Afghanistan are the first to use state-of-the-art handheld nano surveillance helicopters.Update September 2016 replaced missing picture.
The Black Hornet Nano Unmanned Air Vehicle measures around 4 inches by 1 inch (10cm x 2.5cm) and provides troops on the ground with vital situational awareness.
The Black Hornet is equipped with a tiny camera which gives troops reliable full-motion video and still images. Soldiers are using it to peer around corners or over walls and other obstacles to identify any hidden dangers and the images are displayed on a handheld terminal.
This revolutionary new system - the size of a child’s toy - is carried easily on patrol and is capable of performing in harsh environments and windy conditions.
The Black Hornet weighs as little as 16 grams and has been developed by Prox Dynamics AS of Norway as part of a £20 million contract for 160 units with Marlborough Communications Ltd in Surrey.
