I am looking for information on the date of the first flight of the prototype piloted by Kotelnikov or Chtcherbakov. Does anyone know if any of the five prototypes built were used to intercept the U-2?
He had his first flight in December 1956 .Powered by a combined rocket engine and jet engine to reach an altitude of 24,000 meters. They do not use it against u-2 because s-75 is already in use
