What tasks did Borisoglebsk repair plant performed before being targeted by Ukrainian drones

Defense Express explained what kind of repair works the plant was engaged in.

The Borisoglebsk Aviation Plant, located in the Voronezh region of the Russian Federation, is tasked with the repair and refurbishment of various aircraft missiles, including the R-33, Kh-22, and Kh-55. However, on the night of April 9, the plant fell victim to a successful attack by a long-range kamikaze drone.

Andriy Yusov, a representative of the Ukraine’s Main Intelligence Directorate, disclosed this information on Radio Svoboda, indicating that the primary production facilities of the enterprise suffered damage, according to initial reports.

The specific type of drone utilized in the attack remains unknown. Notably, Ukraine possesses sizable drones capable of carrying payloads exceeding 100 kg, which have previously been deployed against Russian arms production sites, such as Alabuga situated across the Volga River.

According to Defense Express, the targeted entity in Borisoglebsk is the "711th Aviation Repair Plant," primarily specializing in the maintenance of air-to-air and air-to-surface missiles, as well as guidance equipment for cruise missiles and various flight radio support systems. While official reports regarding the company's activities ceased publication in 2021 due to heightened secrecy concerning state procurement in Russia, earlier records suggest a focus on aviation guided weapons repair.

Given Russia's increased utilization of cruise missiles like the Kh-55 and Kh-555, alongside the restoration needs of the Kh-22, it's probable that the "711th ARZ" played an active role in these operations, particularly amidst the ongoing full-scale invasion.

It's worth noting that the R-33 air-to-air missile, with a range of up to 160 km, is a key component utilized by the MiG-31 aircraft.
