    No new designation assigned for that variant ?

    In UAC White book there is project to re-engine An-124. The engine is NK-23D (НК-23Д).

    Samara has started to produce NK-32 engines. These should be used in An-124, and not Tu-160 as article states.

    Some interesting photos of a bunch of VKS assets @ Belbek.

    IIRC photos were taken in June, probably during aviadarts. Note the 9 Ukrainian MiG-29s. The rest were delivered before fighting started in the east, then Russia decided to stop process. I don’t think they will ever fly again.

    there is also modernization of IL-76 and most of IL-476 slots are likely to be for A-100 and IL-478.

    Avistar-SP was being modernised, but due to the current crisis the financing has been interrupted and resumed. The quote below is from an interview with Andrei Kapustin, general director of Avistar-SP. It has been translated with google translate. Maybe the situation has changed again…

    The main parameters of technical modernization of the whole process are respected. Of course, one of the consequences of the crisis in the economy has been the suspension of a number of important areas. This is due to the fact that a large part of technical re-done at the expense of budget funds allocated under the special federal program. But at the moment the resumption of funding issues are successfully resolved, work on the frozen objects resumed. Total is currently re-equipment is carried at 11 facilities, of which 5 projects related to the serial production of Il-76MD-90A, 2 objects relate to the production of aircraft components IL-112B, one object of the IL-78 aircraft of 70m2, Anti- 125, and 1 object of universal application for all types of aircraft. For example, at last, it will be completed by the creation of the housing 8/3 site testing of aircraft fuel and leak.

    Note that details on entire fleet are provided in that blog. Let’s hope is not shut down because the posts are really interesting.

    I think due to addition of two new program, IL-114 & IL-112 plus more number of IL-96-400 which were not part of Plan prior to 2014 , would delay the Il-76 program

    These could be reasons too, but Il-96 is produced in Kazan, while Il-114 should be produced at Sokol. Il-76 is produced at Aviastar-SP (Ulyanovsk).

    Il-96 is quite a survivor. At several instances it was considered to end entire production.

    The contract for 39 Il-76MD-90A might be pushed back by 2-4 years (original timeline was 2020).

    Interesting, the likely cause is the reduction in defense budget. This would allow faster deliveries if the type is exported, but it will never be as successful as previous versions due to cost. In the 90s exSoviet Il-76 could be acquired at very low prices.

    In the late 1980s and early 1990s the French Air Force modified the types of Rafales to be acquired.

    – Up to 1992, 250 Rafale; 225 single-seaters and 25 two-seaters.
    – 1992 revision, 231 Rafale: 95 single-seaters and 136 two-seaters.

    The reasons given were that the cost of a WSO was not that high compared to the whole cost of acquisition and operation, and a second crew member was useful in many missions.

    Perhaps somebody can provide more detail.

    Didn’t they abandon the plan to use the Irbis, but went back to a Novella suit?

    Yes, a Novella-45 model was installed. In 2008 it was stated that this was the type chosen, but in 2009 Tikhomirov stated that there were plans to install Irbis in Tu-22/160. In 2013 the decision reversed and Novella-45 was chosen.

    IMO the Tu-22M3 is a good choice. They are plenty of frames/spares (*), and the aircraft offers long range and good payload.

    (*) 370 Tu-22M were inherited by CIS. 210 in VVS and 160 in Naval Aviation. The ones in Ukraine were scrapped but the large majority ended up in Russia.

    What is the difference?

    This is one of the best explanation I have read. It was given in a debate about tanks.

    IR night sights are “active equipment” that require the use of IR searchlights to illuminate the target, in simple terms its the same as using a conventional searchlight but in the near IR wavelength!
    unless the light is actually shining on an object it cannot see it! it also has the handicap of standing out like a lighthouse to anyone with an IR sight switched on!

    TI thermal sights are totally “passive” they emit nothing but read the difference in far IR light, anything that is warmer than the ambient temp the sight has been tuned for shows up as a glowing object, the sight can see this through smoke, dust, rain, fog, mist, light cover, into woodland and shrubbery etc!

    II , image intensifiers are also “passive” they magnify the available ambient light to produce a picture, they require a degree of light to work though (starlight etc). On a pitch dark moonless overcat night for instance, they are basically useless!

    Out of these three options, the TI is head and shoulders above the other two, they simply don’t compare, especially as TI is as useful in daylight as it is at night!!

    an Gen2 IIT based sensor

    If you check Mladenov or Yefim Gordon books on Mi-24 you can find information about the Zarevo system. It integrates a thermal camera derived from a model developed for tanks, named Nokturn.

    Mi-24PNs don’t have FLIR, just Gen2 IIT.

    As I understand it is a FLIR, as it has a Zarevo stabilised thermal sight. It was a rather crude and basic upgrade, but one that Russia could afford in those years.

    The four British ships fired more than 2,800 shells at Bismarck, and scored more than 400 hits, but were unable to sink Bismarck by gunfire.”

    Which makes sense. Bismarck displaced almost 50,000 tons, that’s a lot of volume/space. Most of the hits took place above waterline. When attacking other battleships like Yamato torpedoes only targeted one side to cause capsizing.

    Reason MiG-29 had short range is that no more was required. They were to be operated by almost exact same profiles as MiG-21/23 (ground controlled intercept, slashing missile attack, return to base, repeat if necessary). Even designers thought that very unambitious.

    9.12 range performance was below Soviet requirements. This is why 9.13 was fielded with extra fuel drop tanks and larger internal volume was developed (hunchback).

    Yes, I decided that it was better to resurrect an old thread rather than opening a new one.

    It is interesting to see that none of the later versions have a 50% increase in internal volume compared to 9.12. I have read this claim quite a few times over the years.
