Danish skies may have found its newest defender: a heavy unmanned aerial system (UAS) armed with two .50-caliber machine guns.
Weighing just under 24 kilograms (53 pounds), the “HD-606” combines the firepower of a strike platform and the lifting capabilities of a heavy UAS.
It can carry 50 kilograms (110 pounds) for 30 minutes or haul 25 kilograms (55 pounds) for more than three hours, giving operators flexibility to prioritize direct engagements or protection of critical assets.
The HD‑606 can fly at speeds over 72 kilometers (45 miles) per hour and reposition itself across a target area without leaving monitoring gaps.
Powered by a dual-generator setup, the drone can continue flying even if one generator fails. In the event of a complete power loss, a small onboard battery provides emergency flight.
Each generator can run for 200 hours before major maintenance, and the system can supply up to 1,500 watts to onboard mission equipment.
Less Recoil, More Punch
HD-606 is fitted with a recoil mitigation mechanism that softens vibrations during flight, allowing the drone to fire consistently mid-air while remaining stable.
The guns, developed by Danish firm Small Arms Industries, can engage light armored vehicles, radar systems, and fortified enemy positions, providing troops reliable firepower without exposing themselves or other UAS assets.
Experts noted that the HD-606 is likely the first heavy multi-rotor drone built around a dual .50-caliber weapon system.
The drone made its public debut at Enforce Tac 2026 in Nuremberg.
