A dragon drone also known as "Dracarys" is a type of incendiary unmanned aerial vehicle (UAV) initially developed and dubbed by Ukraine's Ministry of Defense and Ukrainian private defense manufacturers. The drone is used to spray molten thermite, at a temperature of around 2,000 °C (3,630 °F), at military targets in order to burn down natural barriers and fortifications that hold combatant military units. The device was created in 2024 during the Russo–Ukrainian war as a means to destroy forested areas and remove the cover of Russian soldiers. Their first documented use was in August–September 2024.
