Also known as: Black Hornet / PD-100 / Nano Drone
Black Hornet overview
The Black Hornet is the world's smallest operational military drone, developed by Norwegian company Prox Dynamics and later acquired by FLIR Systems (now part of Teledyne FLIR). Weighing just 33 grams with a length of 168 millimeters, the PD-100 Black Hornet is a helicopter-form-factor nano unmanned aerial vehicle that fits in a soldier's pocket and can be deployed in under two minutes. First introduced in 2012, the system carries both electro-optical and infrared cameras capable of transmitting live video and still imagery to a handheld display unit, providing individual soldiers and small teams with organic aerial reconnaissance capability that was previously unavailable at the squad level.
The Black Hornet achieved operational prominence during deployments in Afghanistan, where British forces used the system for compound clearing, route reconnaissance, and over-the-hill surveillance in environments where larger drones could not operate effectively. The nearly silent electric motors make the Black Hornet difficult to detect at operational altitudes, a critical advantage in close-quarters urban and village environments. Public manufacturer and defense reporting has associated the system with military and special-operations users in Norway, the United States, United Kingdom, Australia, France, Germany, the Netherlands, and India, although country-specific delivery and current-service details are not uniformly public. The Black Hornet 3, the latest generation in the source record, features improved flight stability in winds up to 20 knots, enhanced thermal imaging, and GPS-denied navigation capability, solidifying its position as a prominent nano UAV for dismounted military operations.
Teledyne FLIR's 2025 public Black Hornet 4 material describes a new 70-gram nano-UAV with improved range, endurance, survivability, and day/night imaging compared with earlier generations. Those are manufacturer specifications for Black Hornet 4, not evidence that every legacy PD-100 or Black Hornet 3 user has upgraded. The company and defense reporting describe the system as a close-reconnaissance tool; public sources do not support treating it as an armed strike drone.
Through 2026, Black Hornet 4 is best characterized as the manufacturer's current product generation moving through customer demonstrations and procurement, while the existing Black Hornet family remains in service with multiple users. Exact delivery totals and country-by-country fielding dates are not consistently public, so this profile avoids converting the company's launch claims into a universal operational status.
