Johnston Industries is a major Federated Suns-based military hardware manufacturer.
|Primary Site(s)|| Addicks|
|Primary Products|| Aerospace Fighter|
When the Star League collapsed, the wealthy Federated Suns-based Johnston family purchased the Tauken Weapons Systems plant on Addicks, only to watch as the Federated Suns, Draconis Combine and Capellan Confederation desperately attempted to control the planet or deny its foes the production facilities. By the time AFFS succeeded in securing the planet, over half the factories were destroyed. Building upon the surviving assembly lines for man-portable lasers, PPCs and the Goblin tank, Johnston slowly made plans to expand. 
In the late 3060s, the company licensed the Fulcrum Hovertank design from Cyclops Incorporated.
The facilities survived the Capellan's counterattack due to security forces and efforts of the Fourth Donegal Guards during Liao's six-month battle for the capital. However, later strikes by the Taurian Concordat reduced the New Syrtis lines to a radiation-heavy wasteland. Though in theory the New Syrtis lines could operate at nearly three-quarters of it's pre-Jihad output, the government is unwilling to expose workers to the radiation. Until the contamination is cleaned up, these lines will remain offline. To ensure their survival, Johnston upgraded their Benet III component factory to a full production line, but despite work to clear up the contamination on New Syrtis the plant there was still closed to production in the early 3080s.
