... or China. They might have to defend Siberia sometime in the next generation.
Arms experts: How many warheads on a US MIRV?
The Soviet SS-18 had 20 warheads of 1 megaton each. I don't recall how many our big missiles had, but it wasn't nearly as many, maybe 3 or 5. We haven't had to worry about this stuff for a while, and I don't think we have to worry about Russia now, either. If the Russians are developing something that makes them feel safer, it's for internal consumption.
Eight warheads on a Trident II block D.
Especially after Klintune gave away all US nuke knowledge to them.
At last. Someone thinking out of a box :)
The only way to deter Chinese against starting war with Russia is have a 100% guarantee of Russia nuking them in first several hours.
As to building smarter missiles against missile defence systems... This is an ever-lasting competition. Like lock and thief :)
