Russia’s Rare Mi-8 Electronic Warfare Helicopter Reportedly Lost Under Mysterious Circumstances

Russian aviation may have lost a rare Mi-8MTPR-1 electronic warfare helicopter under unclear circumstances, according to several Russian pro-war military aviation-linked channels, including “Voevoda Veschaet” and “Ya i moi drug vertolyot ” on May 18.

According to Militarnyi, the photos they shared online appear to show a helicopter belonging to the Mi-8MTPR-1 variant, a specialized electronic warfare aircraft based on the Mi-8MTV-5-1 platform.

Unlike standard Mi-8MTV-5-1 helicopters, this version lacks a rear ramp and cockpit armor plates, has a narrower left sliding door, fewer windows, and an additional antenna mounted on the tail boom.

It has not yet been confirmed whether a helicopter of this exact modification was actually lost. The cause of the incident also remains unknown. Possible explanations include a Ukrainian drone strike, air defense fire—including possible Russian friendly fire—or a technical failure.

If confirmed, this would not be Russia’s first loss of this rare helicopter type. According to the open-source tracking project Oryx, Russian forces have lost at least five Mi-8MTPR-1 helicopters since the start of the full-scale invasion.

The Mi-8MTPR-1 is equipped with the Rychag-AV electronic warfare system, which includes the L187A jamming suite. The system operates in the 5.1–11 GHz range and is reportedly capable of suppressing up to eight targets at once within a sector of roughly 45 degrees at distances of up to 150 kilometers.

The jamming system is extremely heavy, weighing about 1,200 kilograms—and, by some estimates, up to 1,400 kilograms—taking up much of the cargo compartment of the base Mi-8MTV-5-1 helicopter. The operator’s workstation is located in the forward section of the cargo cabin.

The Mi-8MTPR-1 can reportedly remain airborne for up to 2.4 hours. It typically operates at altitudes of around 3,000 meters to improve the effectiveness and reach of the Rychag-AV system, though its exact operational range has not been officially disclosed.

Earlier, Ukrainian Unmanned Systems Forces successfully struck a Russian Mi-28 and an Mi-17 helicopter at a field landing strip in the Voronezh region.

The operation targeted aircraft more than 150 kilometers from the frontline at a field landing strip housing four Russian helicopters undergoing refueling and inter-flight technical inspections.
