By the way, KDU is used by the Belarusian Pechora-2T and 2TM, not the Russian Pechora-2M. The changes are entirely algorithmic. Unmodified 5V27D missiles are used by the 2T/2TM.
The 2M is supposed to be armed with 5V27DE missiles, on which there is not much information. Apparently, the warhead and fuse were replaced, along with the booster.

It's a
sin to wreck such beautiful hardware!
