North Korea is developing solid-fuel missiles to enhance its national defense capability and improve missile systems. Solid-fuel missiles, like those used in the U.S., China, and France, offer advantages over liquid-fuel weapons, as they do not require immediate fueling, are easier and safer to operate, and require less logistical support. This results in them being harder to detect and more survivable.
