This engine used four vernier thruster, Why ?
it's imply use in second stage,
But 80 tons trust ? i have not found any information on thrust value of this engine.If it's really 80 metric tons then North Korea got chance to build rocket that bring 120 Kg in low orbit Or SLBM in size of R-29 SLBM...

I think this will be used on a first stage initially.QuoteBut 80 tons trust ? i have not found any information on thrust value of this engine.If it's really 80 metric tons then North Korea got chance to build rocket that bring 120 Kg in low orbit Or SLBM in size of R-29 SLBM... That could be the plan. The next step might be to cluster the engines Space-X style and then use this engine on an upper stage. Another possibility is to cluster several cores.
