-Work began on adapting the [[R-3S]] missile with a Semi-Active Radar Homing (SARH) warhead in 1961 under the bureau designation ''Izdeliye 320'', with expectations that it could be used in high-altitude engagements.<ref name="MissileInfoR3">Missilery.info n.d.</ref> Though limited by the dimensions of the R-3S missile, improvements could be made to the warhead, rocket motor, and fins. In the front, a new semi-active radar seeker was installed, surrounded by dielectric fairing. For the rudders in front, a new rudder actuator package was installed that attached an electronic module that adjusts the rudder deflection to better suit the missile's flight based on altitude and target distance. Behind the rudder was the warhead alongside the new ''Yastreb'' radar proximity fuse, the latter which has a diameter wider than the missile's body, creating a bulge in the missile body that contains the fuse's transmitter/receiver antennas.<ref name="Gordon2004_26to28">Gordon 2004, 26-28</ref> It is not known what specific upgrade, if any, were done to the rocket motor. These modifications to the missile increased the length by 580 mm and the weight by 7.1 kg.<ref name="Gordon2004_26to28"/>

-Izdeliye 320 was ready for production in 1965-66, with the missile index designated '''R-3R''' (also known as ''K-13R'', or the US codename ''AA-2C'').<ref name="MissileInfoR3"/><ref name="Gordon2004_26to28"/> The weapon would be accepted into service by 1968.<ref name="Gordon2004pg30">Gordon 2004, 30</ref> The R-3R's SARH seeker allowed for an all-aspect engagement with the target. The missile was effective up to 21 km in altitude, with an effective range between 0.3 to 15 km.<ref name="MissileInfoR3"/> The R-3R was compatible with the APU-13U-2 launch rails, which were installed in later models of the MiG-21 (from ''[[MiG-21S|S]]'' to ''[[MiG-21bis|bis]]'') and early MiG-23 variants.

-As with other radar missiles, acquiring stable radar lock is easiest at higher altitude. The R-3R performs best at and above 2,000 m, however it can lock onto an enemy above you even at low altitude should you pitch up steeply to avoid ground clutter. Due to the missile's relatively low speed of Mach 1.7, long-range intercepts are unreliable as the missile will struggle to intercept before running out of fuel. One good remedy to this issue is to pick up higher altitude targets with your radar and approach from head-on either level or slightly below the enemy's altitude. Spool up the missile but do not fire from further than 5 km out as missile lock can be intermittent beyond this. When fired in a head-on between 5 to 1.25 km, the missile has a significant chance of successful intercept if you maintain radar lock with the target and they fail to make significant evasive action. Missiles fired in a head-on close in at much greater relative speeds thus little time is provided to evade.
