Recently, North Korea test-fired an intercontinental ballistic missile (ICBM) powered by solid fuel. Solid-fuel missiles do not need to be fueled immediately ahead of launch. They are often easier and safer to operate, and require less logistical support. They are harder to detect and more survivable than liquid-fuel weapons. Solid propellants are a mixture of fuel and oxidizer. Metallic powders such as Aluminium often serve as the fuel, and ammonium perchlorate, which is the salt of perchloric acid and ammonia, is the most common oxidizer.
