The horror, the horror. Russia builds the world's biggest microchips too.
Get a clue. Liquid-fueled ICBM's have so many drawbacks relative to solid-fueled ones that no one makes the things unless their chemical engineering is so backward that they can't produce comparable solid-fueled ones. I.e., the Russian chemical industry is 40-50 years behind ours.
All this does is prove that the Russians can't compete even with China in high-tech military equipment.
Liquid-fueled rockets do have some advantages. OTOH continual readiness is not one of them.
This is a formidable first strike weapon if it can be fueled in its silo without any indications of that operation on the surface. Especially if a large number can be fueled and launched simultaneously.
I have known several Russian chemists and engineers.They approach things differently than we do in the west, but we are in great peril if we assume they are stupid or backward.
