A CIWS usually consists of a combination of radars, computers, and multiple rapid-fire medium-calibre guns placed on a rotating gun mount. Examples of CIWS products in operation are

Some platforms use missile systems instead of guns, because guns have certain limitations:
Because of their greater range, a missile-CIWS can also be dual-used as a short-ranged area-defense anti-air weapon, eliminating the need of a second mount for this role.
After an inertial guidance phase CIWS missile relies on infra-red, passive radar/ESM or semi-active radar terminal guidance or a combination of these.

Some systems allow the launch platform to send course-correction commands to the missile in the inertial guidance phase.
