Ukrainian drone units struck two Russian military helicopters at a field airstrip in Voronezh Oblast on April 29, 2026, hitting a Mi-28 attack helicopter and a Mi-17 transport more than 93 miles from the line of contact.
The operation was a joint mission by composite crews from the 429th Separate Unmanned Systems Brigade “Achilles” and the 43rd Separate Artillery Brigade, planned and executed in coordination with Special Operations Center “A” (CSO “A”). Ukraine’s Unmanned Systems Forces (USF) confirmed the strike the same day.
Magyar’s update:
Birds of the USF hunted down and struck two enemy helicopters — a Mi-28 and a Mi-17 — in Russia’s Voronezh region, 150 km from the line of contact.

“The strikes were delivered to the rear central part of the engine compartment, bypassing the main rotor blades,” the USF stated. Targeting the powerplant rather than the airframe concentrates damage on the helicopter’s most mechanically critical region, and avoiding the rotor assembly removes a potential deflection point for the incoming drone.
Four helicopters were at the landing strip conducting rapid refueling and between-flight technical checks when the drones struck. Two were hit. At least one helicopter maintenance specialist was killed, according to the USF, a loss that compounds the hardware damage as trained aviation technicians take considerably longer to replace than the aircraft themselves.

The 429th “Achilles” Brigade has operated continuously since the first day of Russia’s full-scale invasion, growing from a volunteer rifle company into a brigade-level force by January 2026. It functions within Ukraine’s Unmanned Systems Forces, a centralized drone warfare command with no direct equivalent in any other military.
Voronezh Oblast borders Ukraine and has faced Ukrainian drone operations before, including a strike on the Borisoglebsk military airfield in July 2025. The oblast has served as a staging area for Russian aircraft and crew rotations, but back-to-back strikes on aviation assets deep inside the region suggest that buffer is narrowing.
