What type of propulsion is used by the Stinger missile?

• A. A solid-rocket motor
• B. A liquid-fuel rocket
• C. A turbojet engine
• D. A ramjet

Answer: (A)

The propulsion used is a solid-fuel rocket motor. Solid propellants offer a compact, rugged, and highly reliable source of thrust, which is ideal for a shoulder-fired system that must be ready to launch at a moment’s notice and endure rough field conditions. There’s no need to carry separate liquid fuels or oxidizers, nor to manage complex fueling and ignition processes, which makes storage, handling, and maintenance much simpler. In contrast, liquid-fuel rockets require on-board fueling and more complex systems, while turbojet and ramjet engines are air-breathing and add significant weight and complexity, with performance that doesn’t suit a short-range, portable weapon. A solid motor provides the quick, self-contained thrust needed for the Stinger’s design.
