So R77 magically appears on SU27's stationed in syria?
Russia redeployed advanced Su-35S fighter jets to Syria — defense ministry
That's the one I'm referring to when I said:
Only a few years ago they bought a small number of RVV-SD.
Russia's Su-35 was Spotted Armed with a New Missile over Syria | Israel Defense
Video footage shot by a U.S. Navy F/A-18C Hornet squadron over Syria shows a pair of Russian Sukhoi Su-35S Flanker-E fighters armed with a pair of older R-27 air-to-air missiles but what appears to be a single R-77-1 RVV-SD active radar-guided missile. The R-77-1 is the latest and most capable medium range air-to-air missile it in the Kremlin’s inventory, but the Russian Air Force has only a limited stock of the weapons.
They bought a small batch in order to make the production viable and then sell the missiles to the export market.
Before that the SU did buy 200 R-77s, but those never became operational, rather all of them were used for tests. A more advanced version did not hit production after their dissolution. Rather India became the first operator of the R-77.
