Tachibana Heavy Engineering's JT-B laser cannon[1] was the first generation JT-series laser cannon that was both a starship and starfighter-based weapon system used by the New Empire.[1]
The "JT" stood for Jacques Tachibana, CEO of Tachibana Heavy Engineering while the "B" was added to denote this laser cannon from the other JT-laser cannons.[1] This laser cannon dealt weak damage to large capital ships but more damage towards starfighters and freighters, making it the ideal weapon system for most starfighters used by the New Empire.[1]
