What Happened to the Soviet Supersonic Jump Jets?

Soviet Supersonic Jump Jets

Back on the 70’s and 80’s the Soviet Union developed a series of VTOL (Vertical Takeoff and Landing) aircraft that culminated in the supersonic Yak-141, something that the west wouldn’t achieve until the arrival of the F-35B in 2010 some 20 years later. This is the story of the Soviet supersonic jets.
