Black Hornet 3 is a military micro-drone from the Black Hornet family, associated with Teledyne FLIR and Norwegian developer Prox Dynamics. It sits in the helicopter-type nano-UAS class and is aimed at defense, government, and specialist institutional users rather than consumer pilots. Its importance comes from representing the extreme small end of the drone market, where size, portability, and discreet close-range airborne observation matter more than big payloads or creator features.
