    Hunting with a change of places: anti-aircraft missile systems S-350 will travel around Siberia
    Air defense systems "Vityaz" master new tactics

    The divisions of the 24th Mobile ZRBr deployed in the capital of Khakassia, Abakan, will become real “nomads” who can be transferred to any region in the east of the country

    Is there any information what kind of guidance does 9M100 uses is it command guidance or ARH homing ?
    That article is severely munged.
    9M100 is a 15km IR homing missile.
    9M96 has 2 versions 60 & 120km, both with active (possibly AESA) seeker.

    Yes, the 9M100 is supposed to be an interservice weapon, so for the Army it will be used with the S-350 system as a lock on after launch short range guided self defence missile using IIR seeker technology and a datalink. For the Air Force it will be a short range AAM that can be launched from inside and internal weapon bay as used on a stealth fighter or indeed a conventional or stealth bomber that uses an internal weapon bay because its lock on after launch design means it does not need to have a lock before it can be launched. Note the AIM-9X needs to be extended out of the internal weapon bay of the F-22 to get a lock on the target before it can be launched... not very stealthy...

    And the Navy will use the missile as a CIWS type weapon where its lock on after launch capability means it can be stored vertically in low RCS bins and launched in any direction at enormous numbers of incoming threats in a fire and forget mode.

    There have been photos of a 9M100 missile with a radar nosecone that might be an alternative command or ARH guided model... we will need to wait for more details, but it is known to be part of the S-350 land based system with four 9M100 missiles per 9M96 tube so each vehicle can carry up to 12 9M96 missiles of 50km or 150km range, or four 9M100 missiles for each 9M96 tube for up to 48 missiles per launch vehicle.

    The naval Redut system shown so far has had a large fairing for each launch tube when launching 9M96 missiles where each tube could launch a much larger S-300 missile. They have stated Redut can carry 400km range missiles which suggests full sized S-400 or S-300 missiles could be loaded too, so each redut hatch cover could hold a 400km range S-400 or four 150km or 50km range 9M96 or 16 9M100 missiles... assuming only a single layer of missiles is used.

    I believe when they were first revealed the figures were 40km and 120km for range for the two missiles, but they changed them to 50km or 60km and 150km or 160km for the new land models, so I figure 50km and 150km is about right with improved rocket fuels and lighter smaller more compact electronics.

    Some suorces said that 9M96 has a 150 km range ? I did not read that ARES radar in 9M96.
    Yeah there are a bunch of different ranges variously quoted (also shorter numbers come from Export version data-sheets at Industry shows), point is one version of 9M96 is in the 40-60km range, the other in longer 120-150km.

    I'd thought I saw a pic of an AESA head but seems to be not necessarily for 9M96, it should be at least PESA.

    There have been photos of a 9M100 missile with a radar nosecone that might be an alternative command or ARH guided model
    Thats the one that looked nearly exactly like a TOR missile wasn't it? (implied older version might have been abandoned)
    Personally I have my doubts about an IR seeker for a point-defense missile, seems like there would be quite a few modern threats that'd be hard for an IR seeker to find eg modern low-speed small drones & un-powered precision glide bombs.

    Actually I would say the opposite... an imaging IR sensor is ideal for finding low RCS targets... we have seen video from the Farnborough airshow showing the B-2 and F-22 and F-35 clearly visible in IR frequencies, so a sophisticated IIR sensor with a digital database of three D models of objects would pretty much allow the missile to determine what it was looking at in terms of aircraft or missiles on its own would be perfect... a datalink used to change targets if necessary of course...

    All matter gives off IR radiation except when cooled to absolute zero so any bomb or missile or tiny electric powered UAV is visible and able to be targeted by this sensor.... and over short ranges it would be totally all weather.

    They have shown a rather small ARH seeker for some time now... I think it was an AGAT sensor... It was on that Aussie website by Carlos Kopp, there was a lot of speculation about what it was developed for... perhaps for upgrades for OSA or TOR...

    Personally I think a QWIP chip based IIR sensor is the cheapest and most effective option for missile guidance for such weapons as ARH is not cheap... effective but not cheap.

    IIR and ARH could be totally fire and forget, while backup missiles with command guidance could also be an option to allow enormous numbers of missiles to be used without being too expensive, but I suspect a QWIP based IIR sensor, which is just like a CCD CMOS chip that can detect light in IR and UV as well as visible light would be an enormous step forward in terms of cost of production and performance...
