Rosoboronexport, Russia's state arms exporter, announced through its press service on 2026-09-04 that it will showcase the TKB-1167 anti-drone air defense system for the first time at the El Alamein International Airshow 2026 in Egypt. ^[1] Rostec's High Precision Systems holding said it is marketing Biz-on, an export version of its Zubr short-range counter-drone system, to potential customers in Egypt, according to a statement from the company. ^[2] According to the statement from Rosoboronexport's press service, the TKB-1167 consists of a combat module equipped with four tank machine guns and is capable of autonomously and automatically detecting, tracking, identifying, and destroying unmanned aerial vehicles. ^[3] Bekhan Ozdoev, industrial director of Rostec's weapons cluster, said the TKB-1167 is already on combat duty and successfully engaging real targets, demonstrating high reaction speed, and can be used independently or as part of a unified counter-drone defense architecture. ^[4] Rostec said the TKB-1167 Biz-on system is armed with 7.62mm PKT machine guns and designed to engage small, low-flying aerial targets that are difficult for traditional air defense systems to intercept, detecting and tracking drones with its own radar while a human operator makes the final firing decision. ^[5] The Defence Blog reported in January 2026 that the domestic version of the system, known as Zubr, has already been delivered to Russian military units. ^[6] The Rosoboronexport statement said that the TKB-1167 and other air defense systems will be on display in the static exhibition area and at the booths of Rosoboronexport and the High-Precision Systems Holding Company, a part of Rostec, at the airshow. ^[7]
