North Korea’s official news agency has said that scientists have successfully tested the engines of the first and second stages. However, according to the news agency report, it is not clear as to when the new missile system will be completed.

What is solid fuel technology?
Actually, in solid fuel technology, solid propellant is a mixture of fuel and oxidizer. As metal powders such as aluminum often act as fuel, aluminum percolate, a salt of perchloric acid and ammonia, is the most useful oxidizer. In such a situation, fuel and oxidizer are mixed together, which forms a rubber-like substance and then it is placed in a metal casing. In solid fuel technology, solid propellants are a mixture of fuel and oxidizer.
