The Arms Factory, which specialized in the manufacture of diverse starship armaments, could be found in the southeastern sector of Foundry Four. After their creation, these substantial weapons were individually transported via specialized skiffs through the residential zone situated in the foundry's northeastern quadrant, as it was closest to the landing shaft. From there, one of four LAAT/c cargo carriers would hoist the weaponry into orbit, where the Ferra Sector Shipyard would then modify civilian transports for military applications. This factory also manufactured light and medium turbolaser cannons, with twelve units prepared for installation on the Icarii-7.
The adventure book Friends Like These, published by Fantasy Flight Games in 2016, incorporated the Arms Factory as part of the Star Wars: Age of Rebellion roleplaying game.
