A point-defense laser cannon, which can also be referred to as a point-defense cannon if it isn't a laser cannon, functioned as a type of starship weapon installation. These installations, which commonly included laser cannons, blaster cannons, or light ion cannons, served the purpose of protecting large capital starships from attacks by smaller starfighters. Furthermore, point-defense cannons provided a defense against missile attacks. The Adumari Meteor-class Aerial Forts featured laser cannons specifically designed to intercept and destroy incoming missiles in this manner.
Vindicator-class heavy cruisers carried both point-defense laser cannons and point-defense light ion cannons as part of their armament.
