Construction of a larger ship (larger than the 3,200 SU production of the region) must be declared and a design must be submitted at the beginning of construction. See Ship Design Rules
- The design cannot be changed once started.
- Supply units are added to the ship construction until the ship is completed. No other ships can be constructed at this region until the ship is completed.
- If the region is attacked, construction is on hold until the region is no longer under attack.
- If the player building the ship loses control of the region, the ship is scrapped and all progress is lost.
- A player can decide to voluntarily scrap a ship before construction is complete. Scrapping returns no value.
- A ship under construction does not count against the SU limit for the region.
However, it will immediately upon completion. Players should ensure there is room in the region for the completed ship, otherwise some ships may need to be scrapped. See Region Limits
It is recommended that large ship production only be done in your safest regions to ensure completion of the construction.
