Ukraine hits Russian electronic warfare facility making Shahed, Iskander components, General Staff says

Ukraine struck a critical Russian military-industrial site overnight on July 5 that produces components for high-precision weapons used by Moscow to attack Ukraine, the General Staff of Ukraine's Armed Forces reported.

The site in question is JSC VNIIR-Progress, a Russian state institute that specializes in developing electronic warfare (EW) systems, including the Kometa antenna arrays, used to jam satellite, radio, and radar signals.

The institute is located in Cheboksary, Chuvash Republic, about 1,200 kilometers (745 miles) away from the Ukrainian border.

The Kometa antenna is used in Shahed-type drones, Iskander-K cruise missiles, and guided aerial bomb modules — all high-precision weapons used by Russia to strike civilian and military targets across Ukraine.

The General Staff confirmed that Ukrainian weapons reached the target area but said final damage assessments were still underway.

The VNIIR-Progress institute has been sanctioned by both the United States and the European Union for its role in supporting Russia's war effort.

The Iskander-K is a precision-guided cruise missile with a range of up to 500 kilometers (311 miles), frequently used by Russia to target civilian areas. Shahed drones have become a central part of Moscow's airstrike tactics since late 2022 due to their low cost and high payload.

Located on the Volga River, Cheboksary is the capital of the Chuvash Republic and lies deep inside Russian territory. Russian independent media outlet Astra and local Telegram channels earlier reported explosions in the city overnight.

Russia's Defense Ministry claimed to have shot down two drones over the region.

This marks the second known Ukrainian drone strike on VNIIR-Progress. On June 9, explosions and fires were also reported at the facility following another drone attack.
