Black Hornet 4

The Black Hornet 4 is a next-generation nano-sized personal reconnaissance system (PRS) developed by Teledyne FLIR Defense, weighing approximately 70 grams with a rotor diameter of 190 mm and length of 255 mm. Key capabilities include over 30 minutes endurance, more than 2 km range, 10 m/s max speed, high-resolution 12 MP electro-optical camera with low-light performance, 650x512 thermal imager, collision avoidance, GNSS-denied navigation, and low acoustic/visual signature for covert operations. It serves military/defense use cases such as soldier-level ISR for close-range reconnaissance in urban, indoor, and outdoor environments, compatible with ATAK and MIL-STD-810H. Its key differentiator is the advanced software-defined radio datalink, enhanced obstacle avoidance, and superior day/night imaging in an ultra-lightweight, rapidly deployable package.
