Plant producing parts for Iskander and Shahed systems in Cheboksary
In Cheboksary, located about 1,000 km from the Ukrainian border, there is the VNIIR-Progress plant.
The facility is part of the production association ABS Electro. It produces GNSS receivers and antennas for satellite navigation systems such as GLONASS, GPS, and Galileo for the Russian military, including modules of the Kometa type.
These components are actively used in drones, including Shahed-type kamikaze UAVs such as the Shahed-136, as well as in missiles for systems like Iskander-M, Kalibr, and in UMPK kits used for glide bombs.
In addition, VNIIR-Progress produces electrical equipment such as circuit breakers, relays, and contactless modules, which are supplied to the Russian navy, including nuclear submarines of the Yasen-M class submarine project.
In May of this year, Ukrainian drones previously targeted Cheboksary.
The VNIIR-Progress enterprise was among the affected sites, and a large fire broke out at the facility afterward.
The attack on this facility was not the first. The plant was previously targeted in November last year and during the summer as well.
