Laser cannon

Some Transformers—most notably the Decepticon Laserbeak—are specifically armed with laser cannons, although this can also be a generic term for any large ranged laser weapon.
Fiction
Marvel The Transformers comics

Laserbeak was armed with two independently targetable laser cannons, empowered by ruby crystals, that could fly on their own. Laserbeak's Universe profile The Autobot Seaspray was equipped with underwater and surface-to-air laser cannons in hovercraft mode, and in robot mode he could fire the laser cannons through his hands. Seaspray's Universe profile Omega Supreme's tank mode was armed with a laser cannon, which in robot mode was mounted on his head. Omega Supreme's Universe profile Headstrong was said to be more vulnerable to his own neuroses than laser cannon fire. Headstrong's Universe profile In battle station mode, Trypticon had a flashing laser cannon. Trypticon's Universe profile Sureshot once owned a twin laser cannon that formed the basis for the Nebulan Spoilsport's bio-engineered Targetmaster mode. Sureshot's Universe profile Snapdragon had four independently targetable laser cannons mounted on his tailwings in jet mode. Snapdragon's Universe profile In both modes, Windsweeper could utilise two powerful, lock-target, long-range laser cannons. Windsweeper's Universe profile
During the Decepticons' initial attack on the Harrison Nuclear Power Plant, Laserbeak fired his laser cannons with uncanny precision. Power Play! When the Decepticons attempted to take the Ark by force, Laserbeak tore open the ship's hull with a "force beam", most likely from his laser cannons. Raiders of the Last Ark Later, during the battle for Stansham Castle, all that could be heard was "the scream of laser cannon and the howl of rockets". Man of Iron
When Megatron again led his troops to seize the apparently vulnerable Ark he didn't count on Omega Supreme, who took out Skywarp with one shot from his laser cannon in tank mode. Transforming to robot mode to meet the rest of the Decepticons in battle, he blew Buzzsaw to smithereens with his now head-mounted laser cannon but only grazed one of Laserbeak's wings, and the avian Decepticon was able to retreat along with the defeated Megatron. Command Performances!
