Russia begins production of BUH2 Sova and Malik acoustic reconnaissance systems.

According to TASS on July 27, 2024, the Russian Tallamho Design Bureau began the serial production of the second generation of the BUH2 "Sova" acoustic reconnaissance system, which serves as an economical alternative to the 1B75 "Penicillin" artillery reconnaissance system. Additionally, the bureau has also started serial production of the updated Malik acoustic drone detector, available in both wearable and mobile versions.

The Tallamho Design Bureau, established in 2022 and based in Grozny, Chechnya, focuses on dual-use IT innovations. One of its latest products is the Malik-Milli, a compact acoustic drone detector measuring 11x8.5x3 cm, making it the smallest in the Malik series. Specific production figures have not been disclosed.

The Malik series detectors are designed to identify a variety of targets, including drones operating on different frequencies, rangefinders, anti-tank guided missile lasers, and sniper scopes. The detectors compile a library of drone sound signatures, which users can update in real time via internet connectivity, allowing the system to adapt to evolving UAV technologies. Testing has shown that the Malik system can detect rangefinder activity at distances up to 700 meters. Future tests are planned to confirm its capability to detect the dual laser beams of Stinger MANPADS. The Malik detectors are available in two versions: a basic model for protecting dugouts, trenches, and transport, and the individual Malik-mini, which can be attached to military personnel's bulletproof vests.

The BUH2 "Sova" acoustic reconnaissance system is an advancement of the first-generation BUH1, designed to detect enemy artillery and armored vehicles by analyzing acoustic waves from gunfire. The system has been deployed in the Russian operation zone in Ukraine, demonstrating effectiveness in detecting enemy artillery positions at distances up to 7 kilometers. The Tallamho engineers are working on further improvements to increase the system's detection range and accuracy.

The 1B75 "Penicillin" artillery reconnaissance system, developed by the Research Institute Vector under Ruselectronics, serves as a reference point for these new systems. Penicillin is an acoustic-thermal system designed to locate firing positions of artillery, mortars, multiple launch rocket systems (MLRS), and anti-aircraft and tactical missiles. It operates without radio waves, making it resistant to detection and jamming by electronic warfare systems. Penicillin can identify enemy firing positions within a 25-kilometer radius and adjust artillery fire over distances up to 40 kilometers, processing acoustic and thermal waves from shots and explosions to provide precise coordinates within five seconds. It also predicts the impact points of incoming enemy shells.

Mounted on an 8x8 Kamaz-6350 chassis, Penicillin includes a suite of sensors on a telescopic boom for infrared and visible spectrum detection, as well as ground-installed seismic and acoustic receivers. The system operates automatically and effectively in temperatures ranging from minus 40 to plus 50 degrees Celsius, with a radio communication range extending up to 40 kilometers.
