The US military has been testing an incredible tiny nano drone that can be used in secret surveillance missions. Dubbed Black Hornet Nano, this drone measures at only 4 x 1 inches and weights in at 0.04 lbs.
Nano drones aren’t exactly a breakthrough in technology. This type of small drones are now even available on Ebay starting at just $50. However, the Black Hornet Nano is much more advanced than those ordinary drones as it comes packed with both thermal and ordinary cameras. It also has a working range of 0.6 miles with 25 minute flight time on a single charge.
Black Hornet Nano has been in action on the battlefield for a few years. The British military has been using the Nano drone for scout missions in Afganistan since 2013.
