PDCs are planetary bases typically equipped with long-range sensors and missiles. PDCs can also serve as fighter/FAC bases. If equipped with barracks, they make ideal defensive positions for ground forces.
They designed just like ships, but get a substantive armor level for free. Unlike ships they cost no upkeep.
Transporting PDCs
Scrapping PDCs
You cannot scrap a PDC in a shipyard. Instead, you have to destroy them and you can then salvage the minerals from the wreck.
1. on the Individual Unit screen (F6) select the PDC you want to scrap.
2. Either Press the Destroy Ship button at the bottom (if you don't care about the crew) OR select the Damage Control tab & press the big red Abandon Ship button (if you do).
3 Either method will create a wreck, which can then be salvaged using a ship equipped with a salvage module (and teamed up with suitable cargo capacity) - If you have used the Abandon ship method then the crew will be in life pods which can also be picked up.
