In the 60s Russia and the US manufactured thousands with 60s technology. North Korea has access to enough ore to make good enough metals and knowledge from history of what works. The difficult part for them is propellants. Historically they’ve used kerosene and nitric acid but the newer rockets use hydrazine compounds and dinitrogen tetroxide oxidiser, which means either they’ve advanced their chemical industry a lot or they’ve found a supplier. |
