Your Planetary Defence Centre "Final Line" has box launchers. Never tried these in a PDC. What is the reload time for them? Manual or Hangar?
They are standard box launchers, so Hangar reload is 120 minutes, MF reload is 20 hours. Obviously they can only be used once per attack. They are an unusual design for me. While I have used box launchers on PDC's before, usually I'll build one or two with lots of box launchers, to handle massive attacks. These were a desperation move, to add additional surge capacity to my missile bases, when I thought that the Dregluk were going to try to bull their way through my missile envelope and attack at short range with particle beams. Each Final Line base was small enough that it could be built in one five-day turn increment, meaning that I could complete them before the main Dregluk fleet arrived. Unfortunately, or fortunately, depending on your viewpoint, the Dregluk instead have attacked with missiles and the Final Line bases have never been used. Especially as they can't use the latest Bludgeon LRASM's as their fire controls have a max range of around 40,000,000 kilometers.
