This is something that requires a great deal of detail as far as how before we get into why.
It require to major changes either Nasser live longer allow USSR get big foothold in which the Israeli and USSR fought more air duel leading greater amount USSR control just military took over or Israel start taking red early in which the USSR. Meaning USSR call temporal halt in fighting and brought pilots, technology crew and so on. Pull USSR even deeper into Egypt until took over.

"It requires major changes. Either Nasser lives longer, allowing the USSR to get a bigger foothold (If the Israelis and the Soviets fight more air duels, this could lead to greater amounts of Soviet military presence and therefore control), and allowing their military to take control. (I think the "Israel start taking red early" means the Israelis fight them earlier) The USSR calls a ceasefire, to recuperate their losses, and bring in more pilots, more advanced weaponry, better crews etc. This pulls the USSR deeper into Egypt (Egypt becomes instrumental in Soviet policy in the region, like South Vietnam for the USA) and the USSR installs a communist government."
