Ukraine’s Defense Intelligence Drones Hit Russian S-300V Launcher and Two Niobium-SV Radars in Donbas

Servicemembers of the Defense Intelligence of Ukraine (DIU) hit a launcher of the Russian S-300V air-defense system and two Niobium-SV radar stations in Donbas.

The DIU press service published the report and footage.

Ukrainian defense forces used drones to strike high-value elements of Russia’s air-defense network.

According to the DIU, the strikes, aimed at degrading the invaders’ ability to control the airspace, were carried out on November 29, 2025.

At night, drones located and hit a 9A83 launcher of the S-300V surface-to-air missile system, which was on combat duty.

The system is designed to protect troop formations and key facilities from ballistic and cruise missiles, as well as aircraft. Its destruction or disablement is considered important for the Defense Forces’ further operations in this sector.

In addition, DIU drones then struck two Russian 1L125 Niobium-SV radar stations.

Niobium-SV

The 1L125 Niobium-SV is a mobile three-coordinate meter-band radar system developed for the air-defense forces of the Russian Army’s ground troops. It entered service in 2016.

The radar is designed to detect, track, and identify all types of aerial targets — aircraft, helicopters, cruise and ballistic missiles, and drones.

The radar reportedly operates over a range of 5 to 500 kilometers, with a maximum detection altitude of 65 kilometers.

Its antenna is mounted on a four-axle KamAZ truck chassis. The radar crew consists of three people. The system can simultaneously track up to 300 targets.

Recently, Ukrainian drones penetrated Russian air defenses and hit three launchers of the Buk-M1, Buk-M2, and Tor-M2 surface-to-air missile systems.
