That requires knowledge also of the mass of the launch vehicle and duration of the engine burn.
Do we really know that much about the Nork “space program”?
We at least do by class of launch vehicle. Stage/vehicle length, stage diameter and fuel composition (solid or liquid) can be pretty much compared to known standards. Even an educated guess would tell us the difference between a 2,000 pound payload and something more or less.
The reason I chose 2,000 lbs is that it is the composite internet listed weight of the MK-21 RV/MK-84 (800 lbs) and a primitive control and maneuvering buss estimated at 1,200 lbs.
It is very likely that a long term orbiting system capable of maneuvering would weigh much more because of fuel on board requirements. Also a crude nuke would weigh much more than a MK-21. So we are looking at a class of launch vehicle that would put up something like a 4,000 ++ pound payload into low earth orbit.
For reference, Trident missile puts a 6,200 pound payload into a ballistic arc and does not achieve orbit. Think the NORKS can beat that yet much less achieve orbit with that kind of payload?
