  1. Gunner's sight for sure will have a bulb and glass reflector....and that's all :). This is PKV, the same simple collimator like we have in Mi-8 module.
  2. Very precise numbers of soviet losses in Afghanistan War are known since 90's. No need read some colorized, tabloid style stories. Through 10 years of war Soviets loss 118 aircrafts and 333 helicopters, these numbers include everything: combat losses, accidents, machines destroyed on ground etc. From 1979 to 1989, and Stingers were in use from 1986...., even in first days of use, one aircraft/helicopter was hit ( which not means automatically being a shot down ) for every 20 fired missiles, when all Soviet aircrafts operated in Afghanistan have been equipped with flare dispensers this ratio go
  3. Yea, you right, I should add info about engines, so: Su-17/Su17K - AL-7F Su-17M/Su-20/Su-17M2/Su-17M3/Su-17M4/Su-22M4/ Su-17UM,/Su-17UM3/Su-22UM3K - AL-21F3 Su-22/Su-22U/Su-22M/Su-22M3/Su-22UM3 - R-29B-300.
  4. Su-17 Family tree is a bit complicated, so I did diagram. I hope this will explain most confusions.
  5. Beamscanner, we already had here discussion about this. Russian specialists from "Fazothron" ( radar creator ) called RP-23 a "pulse doppler with external coherency" and they considered this device as a "pulse doppler". Believe me or not but they don't care what was said by some dude from USA, so please give a break.... .
  6. Fishbed had 4 generations; 1. generation: F, F-13 type 72, F-13 type 74, U type 400, U type 600, 2. generation: PF, PFS, PFM, FL, R, US, 3. generation: S, SM, SMT, M, MF, MT, UM, 4. generation: BIS type 75A, BIS type 75B
  7. This must be written: Many people comparing Soviet RSBN to western TACAN system but those are totally DIFFERENT stuff. TACAN is "only" radio beacon receiver with distance measuring channel, RSBN ( under this name we have several systems like RSBN-2S, RSBN-5S, RSBN-6S, A-321, A-324 etc) is a navigation calculating complex, which use "dead reckoning" concept. In every RSBN type main basic mode is automonous mode when system is calculating aircraft position with data taken from aircraft's systems ( like speed, drifts, course, etc), but because this kind of navigation have growing error duri
  8. Yes, Ramsay have right, RSBN-5S works with true geographic radials not with magnetic radials. Course system KSI feeding RSBN-5S with magnetic radials and then those are changed to geographical in magnetic correction device. Of course this system is not super precise, but precise enough in late 60's. Many Soviets aircrafts of that era had the same, identical RSBN-5S system, so shouldn't be any differences in work between them ( L-39, MiG-21Bis, Su-15T/TM, Su-17/M/Su-20). So far only L-39 have proper implementation, still few things can be improved, but generally L-39 is a point of reference for
  9. Soviets didn't have to and what is more important didn't wanna to convince anybody because till today docs about those old radars are secret. For sure they wanted keep in secret almost all theys achievments because then is much easier suprise and defeat people/nations thinking stereotypes. They get the same goals with different way. Well, that your right to do this, and I'm sure that NIIR ( S-23 creator) have the same way of thinking about Lincolns Lab theorems. They called this radar: doppler-pulse with external coherency and I respect this, especially that in DCS is impossible to catch
  10. According pdf you attached, initial serial AN/APG-66 were delivered in June 1978, for comparison RP-23 development started in 1964 and first production radar show up in 1969 with MiG-23 "model 1969" production (RP-23L).
  11. I think that biggest weakness of this design was analog computer, probably much slower like digital, but this is radar from end of 60's so complaining is misplaced. F-16's radar is 10 years younger at least, and over that time digital techniques did big step forward. Lot of info in Osprey Dual 72 and many others is just bullshits, even today is hard to get access to full RP-23 documentation. R-24 had almost 50 km range ( not used in Iraq ), target like F-15 was tracked "head on" from distance 60 km ( at med and high altitude ), and one more thing: weapon system of MiG-23MLA is a combination of
  12. I know this discussion and I know Mr.Detonator, we had lot of interesting discussions about MiG-21 and 23 on polish forums ( he is from Czech ). You only picked up one of this discussions points of view: which terminology is more correct - Western or Soviet, because in many cases both sides use the same words for differents things. According Soviet terminology RP-23 is a coherent pulse-doppler radar with external coherency. It's uses doppler filters to analyze/process signal, some people says that only radars with internal coherence can be called pulse-doppler but this is only matter of termin
  13. Su-25 had weapon system taken from Su-17M3, which was development of system fitted in Su-17M2......:music_whistling: which was the same like in MiG-23B/BN so yes stuff from Su-25 is a bit more advanced. Photo of ASP-17 symbology, you have to be aware that MiG-23B have ASP-17, Su-25 have ASP-17BC which are very different devices which use the same optical head S-17VG : All MiG-23 variants had afterburner, difference was in engine types.
  14. No, no any kind of DMT on MiG-23B/BN, this aircraft is from 1971....., Pepin yes this is little weird but MiG-23B/BN don't have AAM's, MiG-27 had them, Su-17 of any variant had them but B/BN don't.:joystick:
  15. First: is hard call MiG-23B/BN weapon system a "Prnk". This abbreviation means "Navigation and aiming kompleks" and in Soviet terminology means attack and navigations devices connected in one system by central processing unit. In MiG-23B we don't have central computer so no "Prnk" but two separate navigation and attack systems connected by some funcionality. Two main electronic systems on MiG-23B's board are: Sokol-23 attack system ( Sokol-23S for MiG-23B and Sokol-23N for MiG-23BN ) and navigation kompleks KN-23. Sokol-23S had five main parts: shooting sight ASP-17 with optical head S-17
