A prototype of an air defense UAV was presented in the Czech Republic The operational-tactical UAV GRYF, carrying weapons against UAVs, was presented at an exhibition in Prague. The device is able to carry up to 50 kg of cargo for 12 hours and a range of 500 km. Cruising speed - 150 km/h. The UAV searches for enemy UAVs using an optical-electronic tracking system. The GRYF configuration was demonstrated with Ukrainian interceptor UAVs ODIN Win_hit (on 4 pages), which develop a speed of 200-220 km/h, and during the attack - up to 300 km/h, which allows them to be used against kamikaze UAVs powered by a piston propeller. At the same time, the possibility of using the GRYF with Estonian Mark 1 mini-missiles, which can hit jet UAVs at a range of up to 2 km, was announced. It is not the best development in terms of technical characteristics, however, the idea itself is a logical development of the air defense system against UAVs. It is bad that we see such developments from the enemy, and not in our skies. UAV fighter jets and anti-UAV ground air defense systems are an effective and cheap means of dealing with mass attacks of enemy UAVs, which must be "caught" at vast distances. "Two majors".
