2-Min Summary
missile, a rocket-propelled weapon designed to deliver an explosive warhead with great accuracy at high speed. Missiles vary from small tactical weapons that are effective out to only a few hundred feet to much larger strategic weapons that have ranges of several thousand miles. Almost all missiles contain some form of guidance and control mechanism and are therefore often referred to as guided missiles. An unguided military missile, as well as any launch vehicle used to sound the upper atmosphere or place a satellite in space, is usually referred to as a rocket. A propeller-driven underwater missile is called a torpedo, and a guided missile powered along a low, level flight path by an air-breathing jet engine is called a cruise missile.
