72 Hours of Fire—Ukrainian Drones Smash Russian Air Defense Systems, Iskander Bases, and Fuel Hubs, Video

Ukrainian drone units carried out a wave of coordinated strikes over two days, targeting Russian air defense systems, missile infrastructure, and fuel logistics across a wide front stretching from eastern Ukraine to occupied Crimea, according to a statement published by Ukraine’s Unmanned Systems Forces on April 16.

In the Zaporizhzhia region, operators from the 1st Separate Center of the Unmanned Systems Forces identified and struck a Buk-M1 surface-to-air missile system.

The Buk-M1 is a key component of Russia’s layered air defense network. It is capable of engaging aircraft, cruise missiles, and other aerial targets at distances of up to 35 kilometers and altitudes reaching 22,000 meters.

Further east in the Donetsk region, Ukrainian units hit enemy support infrastructure, destroying a workshop and a storage facility linked to Rubikon drones. The strike is expected to limit Russia’s ability to deploy unmanned systems in that sector.

The 414th Separate Brigade, known as “Birds of Magyar,” conducted operations across multiple directions. In the Donetsk region, they struck an Osa-AK air defense system along with enemy armored vehicles.

The 9K33M2 Osa-AK (NATO: SA-8b Gecko) is a Soviet-era, short-range, amphibious, self-propelled surface-to-air missile (SAM) system, introduced in 1975. It is fully autonomous, featuring search and tracking radars on a single 6×6 vehicle, capable of engaging aircraft and helicopters with up to two missiles at a range of 1.5–12 km.

In occupied Crimea, Ukrainian drones targeted a Pantsir-S1 air defense system, continuing efforts to degrade Russia’s protective umbrella over the peninsula.

The Pantsir system is considered one of Russia’s more modern and critical air defense assets. According to Ukraine’s Security Service, the cost of a single Pantsir system is estimated at between $15 million and $20 million.

Additional strikes were reported against areas used to base Iskander tactical missile systems near the settlements of Kurortne and Mizhhiria.

Fuel infrastructure was also hit in separate operations. Oil depots in Oktyabrske and Hlybokyi Yar were struck, with fires breaking out at both locations. According to Ukrainian officials, the damage could disrupt fuel supplies to Russian forces operating in the southern theater.

“Our objective remains unchanged—the systematic weakening of the enemy until its forces are fully exhausted. We are increasing the pace: more pressure lies ahead, scaling successful operations, and introducing new tactical solutions,” the Unmanned Systems Forces said.

Earlier, Ukrainian drone operators destroyed a Russian Tor-M1 air defense system in the temporarily occupied Donetsk region after an engagement in which the system shot down two incoming drones before being overwhelmed.
