Unlike the Kh-47M2 "Kinzhal" aeroballistic missiles, whose speed in the dense layers of the troposphere decreases from Mach 10 to Mach 4-3.5 due to aerodynamic drag and the absence of prolonged engine operation modes, the 3M22 "Zircon" hypersonic cruise missile can fly at speeds up to Mach 5.7-7 all the way to the approach section of the trajectory.
For the enemy, in case of attempts by the Patriot SAM system, a minimal time window for interception will remain.
This is achieved due to the ability to regulate the intensity of the liquid fuel charge supply to the combustion chamber of the hypersonic ramjet engine, which ensures its operation throughout the entire flight path without reducing speed to Mach 3.5-3.
Therefore, the temporary "window" for this for the Patriot PAC-3MSE SAM system calculation is at least 2 times smaller than in relation to the "Kinzhal". Nevertheless, with distributed AN/MPQ-65 radars, this probability exists, because the speed of the tracked targets for them is 2100 m/s.
Earlier www1.ru reported that the Russian Aerospace Forces began to use ultra-long-range bombs with UMPB.
