There are multiple thread, so posting the space launcher related stuff here… if possible merge the two.
Good input regarding the latest missile launch and the new ingeniously designed engine that Koreans used for this missile test.
Even though they used this brand new engine for a new missile test of historic significance (not sure if this is what they meant when they tested those engine), I don’t think for a strategic missile system, they will stick to it. Its going to be replaced by a solid motor if we go by their recent track record. But this new liquid fueled engine is going to be the base for their current and planned future space launchers.
