The targeted enterprise is part of Russia’s military-industrial complex, producing gyroscopic instruments, control systems, onboard computers, and components for Kh-32 and Kh-101 missiles as part of the Tactical Missiles Corporation, sources in Ukraine’s SBU Security Service told NV on Aug. 11.

Preliminary reports said at least four SBU drones struck the site, the sources said.

“Russian defense industry enterprises working on the war against Ukraine are entirely legitimate military targets. The SBU continues work to demilitarize facilities producing weapons for terrorizing peaceful Ukrainian cities,” an SBU source told NV.

As Defense Express earlier reported, the Plandin Arzamas Instrument-Making Plant, targeted by Ukraine’s long-range drones, is a key producer in the Russian Kh-101 missile program.

According to Ukrainian intelligence, the facility in Arzamas specializes in developing and manufacturing gyroscopic instruments, control systems, onboard computers, steering actuators, testing and calibration systems, and more.

Its work includes navigation systems for Kh-32 missiles, damping gyroscope blocks for Kh-101 missiles, and self-destruct systems for the Kh-59 missile family. Similar components could also be produced for new types of Russian missiles, Defense Express wrote.

Analysts said FP-1 drones may have been used in the strike. Notably, videos of the attack circulating online show no Russian air defense systems in action, despite Arzamas hosting several defense industry facilities.

The city of Arzamas in Russia’s Nizhny Novgorod Oblast is about 700 kilometers from Ukraine.

A series of explosions was heard in Arzamas overnight and in the morning, followed by a fire at the local instrument-making enterprise, APZ. The aggressor state’s Defense Ministry claimed it had “intercepted” two drones over Nizhny Novgorod Oblast on the morning of Aug. 11.

The military war may be swinging in our favor, but the information war continues.

Just as an army needs soldiers, so does a free society need its journalists to ensure that people have access to honest, trustworthy voices to understand the world around them.
