abstract | - In military parlance, powered munitions are broadly categorised as follows:
* A powered munition that expends all fuel upon launch is known as a rocket.
* A powered munition that holds two rocket motors (one for launch, and one to maintain trajectory) is known as a missile (or guided missile.)
* Powered munitions that travel through water are called torpedoes. However, the distinction can become somewhat blurred, especially where a weapon begins as an unguided rocket and is then fitted with a guidance system - e.g. the GMLRS system is still referred to as rocket artillery, despite employing guided munitions.
