Q1) What is a cruise missile?
Cruise missiles differ from ballistic missiles in that they fly towards their target at lower altitudes, remaining within the Earth’s atmosphere throughout their trajectory. Cruise missiles are defined as “an unmanned self-propelled guided vehicle that sustains flight through aerodynamic lift for most of its flight path and whose primary mission is to place an ordnance or special payload on a target.”
