Here answers on your questions:
- R23T/R - 0,6 for large slowly manouvring targets type B-52 for example (theoretical number not considering using defensive aids by target) - export version MF can use either of them but not simultaniously, Soviet airplanes can use both type of medium range missiles simultaniously - R-23 was basically useless against fighter type targets, any hard maneuver depleted missile energy pretty quicly
R-60 - 0,8 again this is theoretical number
- aircraft endurance reached 5 hours for the high/economical flight profile - using afterburner can eat all your fuel within 3 minutes
- radar range it is very complex question - but simplifying B-52 size targets it may be around 50km close to maximal range of R23 missile, now you may compare RCS of B-52 to any given type and estimate detection range drop (detection range is NOT equal to the radar lock range), in many cases thermolocator was significantly more combat effective than radar
- most effective tactics was GCI, very low level approach using ground clutter to hide airplane from fighters and AWACS radars, mutidirectional attack to saturate decision making system, airplane radars off to limit ECM effectivenss, use thermolocator mainly and last time near vertical zoom attack, surprise effect was a key
