The new NK icbm is huge.
The TEL that carries it is also huge. Its a 11 axis truck. Chinese/Russian ICBM TEL trucks dont exceed 8 axis. Does anyone knows if it was NK that developed it or china/russia/belarus sold them? and is it wise to use such a large truck?
The North Koreans need to convert their missile systems to solid rockets. Then the missiles wouldn't be as large.
It is so big because it is a liquid fueled rocket with low propellant density. But for deterrence these systems are good enough.
In the past the North Koreans bought their large TELs from China.
