The Ukrainian side stated that the Russian military modified the Dan-M target drone into a suicide drone to attack Ukraine. These target drones are usually used by the Russian military to simulate cruise missiles for anti-aircraft units to intercept. After modification, the range of the Dan-M target drone is approximately 350 kilometers, with a maximum flight speed of 700 kilometers per hour. The Russian military can use Mi-8 helicopters to carry two modified Dan-M target drones at high altitudes for release to achieve greater range.
There are many Dan-M target drones in the Russian military inventory. Using these drones as suicide drones makes them harder to intercept because they are typically used to simulate cruise missiles, resulting in a smaller radar cross-section.
