Missiles and rockets are the same but with only a difference. A powered but unguided munition(materials used in war) is known as a rocket
while a powered, guided munition is known as a missile.
A ballistic missile
is a missile that follows a sub-orbital ballistic flightpath with the objective of delivering one or more warheads to a predetermined target. Ballistic missiles are largely used for land attack missions and normally associated with nuclear weapons. Ballistic missiles are primarily surface launched from mobile launchers, silos, ships or submarines, with air launch being theoretically possible using a weapon such as the canceled Skybolt missile.The Russian Topol M (SS-27 Sickle B) is the fastest (7,320 m/sec) missile currently in service
A cruise missile
is a guided missile that carries an explosive payload and is propelled, usually by a jet engine, towards a land-based or sea-based target. Cruise missiles are designed to deliver a large warhead over long distances with high accuracy. Modern cruise missiles can travel at supersonic or high subsonic speeds, are self-navigating, and can fly on a non-ballistic, extremely low altitude trajectory.
Some other missiles are Anti Ship missile
Anti Tank missile
The first missiles
to be used operationally were a series of missiles developed by Nazi Germany in World War II. Most famous of these are the V-1 flying bomb
, both of which used a simple mechanical autopilot to keep the missile flying along a pre-chosen route.
