(SAM S-75. Methods of guidance and trajectory of a missile)
From 1965 to 1972, the United States lost in Vietnam (for all reasons) about 10,000 aircraft and helicopters and about 600 drones. Only with the help of RPG-7 grenade launchers, 128 american helicopters (according to American data) were shot down. This is more than all aircraft and helicopters were shot down in all wars by MANPADS Stinger. Approximately 200 American aircraft and helicopters were shot down using MANPADS Strela-2.
After the Americans came out of the war, having suffered a defeat, they left more than 1000 airplanes and helicopters for South Vietnam so that he could continue the war. All these airplanes and helicopters from 1973 to 1975 were either shot down or captured by the forces of North Vietnam.
A major role in the defense of North Vietnam was played by the S-75. Wi
