Excellent photo report of the project 21631 Uglich.

nice. especially the closeup of the Kalibr VLS. Seems cold launch to me, using explosive charge as gas generator instead of High pressure gas bottle found in S-300 family.

Hell yeah.. time to enter heavy engine area. Those AN-124 and future generation of Russian heavy lifters are bound to need a new engine soon.

God Whyyy.

what i wish i could see is discussion about array technology in S-400 or whether S-400 still use high PRF (Up to 100 kHz) burst.

The PS-05 brochure is very informative. Except that “X” distance.

I found this image of the system
anyway, should the IR channel allow pilot to see target at night ? ( like how A-10 pilot sometimes use AGM-65 )

does that thing lack TV channel too ?

Doubt it.

If it does have such ability. Russia would not develop or offer Zarevo sight. Or just entirely replace raduga with more modern GOES.

Mi-24V with GOES, notice that raduga sight is no longer in place.

Zarevo

So in short, those early Mi-25 and Mi-35 for export, lacks thermal imaging or nightvision ability.

Why?, it is still a thermal system is it not?

It does not have TV Channel. It’s not image target. The IRST operator cannot really see what he really shootin at just like radar.

It’s rarely mentioned though that there are actually differences between IRST and a FLIR. The former does not really need TV channel as it task is to determine angular position of target. Frame rate wise there also differences where IRST can have slower frame rate of 10-15 FPS while FLIR need to do as good as our TV set at 60 FPS.

Only recent OLS-35 have TV channel.

Integral characteristics effective area reflecting of target. effective area reflecting / эффективная площадь рассеивания (ЭПР) – RCS

What’s at the Y axis ? Frequency ?

What was the RCS requirement at the time A-12 or SR-71 developed ? If it met that requirement then..it can be considered stealth.
