The russians shave always had good mathematicians. They came up with the theory which led to Have Blue and the F-117. IIRC different theory was developed for subsequent "rounded" stealth aircraft.
As someone mentioned, the soviets didn't know what they had at the time.
The soviets russians also had more money and infrastructure to actually build things, the CIS russians not so much...
