Di Tron Heavy Industries was a major Japan-based corporation. Operating during the Terran Alliance, the Terran Hegemony, and later the Star League, its primary area of interest was construction.


Founded in 2203, The company's headquarters were located in Tokyo, Japan on Terra, with regional offices on New Earth, Sirius, and Zebebelgenubi. Despite its origins, the company had a very rocky relationship with the Draconis Combine, stemming from a dispute between the Toshimotos and Kuritas. Who started the disagreement is unknown, but it is believed one had offended the other sometime in the twenty-third century.[1]

Di Tron secured its first WarShip contract with the Terran Alliance, constructing the rugged and durable Dart light cruiser, a class that continued service through nearly 200 years and the waning years of the Star League.[3] Di Tron became interested in the Lyran Commonwealth when the Commonwealth first began looking into domestic WarShip production in 2371; as a result of the combination of extensive financial chicanery on the part of experienced Lyran businessmen and the knowledge and know-how in WarShip construction held by Di Tron, a new company—Ioto Galactic Enterprises—was created in the Commonwealth, carefully avoiding the legal constraints around sale of restricted Terran Hegemony technologies, and in 2375 the first Commonwealth-class cruisers emerged from the Port Sydney Naval Shipyards.[4] During the Hegemony era, Di Tron had a hold of a large share of the construction market, with subsidiaries focused on urban and military construction. The company built the Nightwing surveillance corvette throughout the Age of War Era for the Hegemony,[5] and with the creation of the Star League, the company diversified, with Di Tron Shipbuilders pumping out quality craft from its ten shipyards.


The only known Di Tron heavy Industries manufacturing center to survive the first three Succession Wars was the Port Sydney Naval Shipyards in orbit above Alarion in the Lyran Commonwealth,[6] which became part of Ioto Galactic Enterprises when the rest of the company was destroyed.[1] Di Tron's shipyards in the New Earth, Sirius, and Zebebelgenubi systems were destroyed during the First Succession War.[1][7]
