Iran unveils new ballistic missile

The missile, dubbed Ra’d-500, is said to be packed with engines, made largely of composite materials. It has significantly lightened the build and the new munition is two times lighter than an earlier model — Fateh-110 missile. The engine, containing carbon fibers, is said to be able to withstand pressures as high as 100 Bar and a temperature of up to 3,000 degrees Celsius.
