Proton torpedo/Legends

The proton torpedo is a weapon from the Star Wars universe. Small starfighters like the Rebel Alliance X-wing and Y-wing starfighters often have their laser weaponry complimented by ordnance launchers capable of firing proton torpedoes. The energized torpedoes carry a devastatingly powerful blast, and can be fired at much greater ranges than the standard laser cannon. During the Rebel attack run on the Death Star I, Alliance fighters had to use high-speed proton torpedoes on the thermal exhaust port that protected the Death Star's sole vulnerable point. Since the port was ray-shielded, standard laser weaponry would have been ineffective.
