Russia has now deployed S-350 Vityaz to one of the airfields used for the Ukraine war. S-350 ‘Vityaz’ simultaneously repels strikes of air attack weapons from any direction. S-350 is capable of striking targets within a radius of 60KM & at an altitude of 30KM. The S-350 ‘Vityaz’ could cause big problems for attacking close-air-support aircraft. S-400 and S-500 air defenses are capable of detecting and striking stealth aircraft.
