American aircraft are using a combination of UV MWS, flares and Directional InfraRed Counter Measures (DIRCM) to defend themselves. Russian armed forces are seemingly following the same approach. The system that is being increasingly installed on all Russian helicopters, and also on some fixed wing aircraft, is the Vitebsk BKO L370, more commonly known with its export designation President-S, first appeared in 2015/2016, the Vitebsk L370 in its complete configuration is designed to protect an aircraft from both IR and radar-guided missiles, which “can be tracked within a radius of several hundred kilometers”. The Vitebsk is actually a modular system with components installed both inside the aircraft or on external attachment points.
