    Probably because we don't hear about such approach being used.

    What approach have we heard about new generation missiles they are designing for their new stealth fighter specifically to deal with US and western 5th generation stealth fighters...

    We have seen ground based radar becoming multi frequency systems, we have seen an increase in multi channel systems including an anti radiation missile fitted with IR ports for anti radar use... hell, in the 1990s they added IR sensors to their Self forging fragment anti tank submunitions that used MMW radar to detect and attack armoured vehicles... why do you think they would continue to use X and Ku band radar seekers against aircraft designed from the outset to be hard to see in those frequencies. Especially when taking in to account the Iskander non ballistic missiles are intended to take out ABM sites in europe...

    When the enemy has ATGMs is the solution just to make more tanks?

    They have had time to think about this...

    Maybe because of ID problems of the target or dome heating issues with high speed missiles affecting IR.


    We have seen open air facilities they use for radar and optical and IR signature generation of objects... they create a 3D object and present it to various radar and optical and IR sensor and rotate the 3D object to view it from every angle and record that signature in a database of 3D signatures.. isn't it pretty obvious why they might be doing that?

    What problems did they have with the R-40T or R-40TD IR guided missiles? Most IR sensors are cooled by liquid nitrogen systems... how hard would it be to also cool the optical port for the sensor?

    How do R-73s cope when loaded on MiG-31s and flown for 30 minutes or more at mach 2.5?

    There was the IR version of the R-27 but nothing apparently about R-77 whatever the reason is.

    Well the fact that there were no orders from Russia for the R-77 until after 2008 suggests there probably wasn't money for many variants either, besides, they already had plenty of R-27s available and still carry operationally in Syria and in Russia.

    In future multispectral seekers should be used, with radar, IR, optical or even acoustic footprints of the target being used to avoid countermeasures, until the only option will be to destroy the missile itself with small, short range self defence missiles / ammo or sheer RF power.

    What... now you think it might be a good idea?

    More sensor means need better and bigger batteries.

    Bigger is not better for batteries, newer batteries offer more power and better duration which is better, but it is also better to make them as small and light as possible.
    Scramjet powered missiles could use an electric generator to power onboard systems...

    Not saying multimode seekers are a bad idea, simply that we haven't seen many developments in this direction AFAIK in the field of AAMs and there is probably some reason, even when we don't know. It can be purely economical or anything else, I don't know.

    Heating is an issue for IR seekers, a bigger problem the higher the speed. Just a thought about possible causes for AAM s and SAMs not having this kind of seeker more commonly beyond short range, lower speed ones, but have not researched on that deeper.

    One question who can answer.

    Can photonic radar that Russia is working on can detect LO aircraft with high reliability including those designed to evade L & S band wavelength like B-2 or PAK-DA types ?

    Can they scale this Radar up to like S-400 class Radars ?
