This is the menu used to use your own shipyards. To open it, select any of your shipyards and press the “Comms” key (default: E) or press the button in the bottom panel. You can also access it from the Asset List.
This is a fairly straightforward menu, you can queue up to 20 items in the shipyard with the ability to loop, allow them to join up with a control group. You can also prevent the manager from using this specific shipyard, and there's 2 buttons to pause and resume production.
By default, ships come with semi randomized loadouts. However, for an increase in production cost, you can customize the equipment. Use the Equipment Presets tab to set personalized weapon and shield presets.
