Squadrons of what? GBIs?
If we use the following assumptions:
- conservative view of US BMD (vs say Russian alarmist one)
- estimate of DPRK ICBM based on the known R36 series performance but adjusted for number of engines.
We would see that H-14 could carry 2-3 RVs, if developed to the Soviet 80s technology, which they may have acquired from disgrunted Ukrainian enginiers (
