In modern language, a missile, also known as a guided missile or guided rocket, is a guided airborne ranged weapon capable of self-propelled flight usually by a jet engine or rocket motor. Missiles have four system components: targeting/guidance system, flight system, engine and warhead. Missiles come in types adapted for different purposes: surface-to-surface and air-to-surface missiles (ballistic, cruise, anti-ship, anti-tank, etc.), surface-to-air missiles (and anti-ballistic), air-to-air missiles, and anti-satellite weapons.

The latter requirement has pushed India to develop longer range missiles and to diversify its delivery platforms beyond mobile land-based missiles. To this end, India is developing ship- and sub-launched ballistic missiles, and has collaborated with Russia on cruise missile development.
