This mod will replace many parts from the original content converting the game in a complete Star Wars mod with 9 factions. Rebel Alliance, Galactic Empire, Black Sun, Old Republic (Clone Wars), CIS, Krayt Empire, Fel Empire/Galactic Alliance, and other three factions which I have not choosen by the moment.
Here you can see the Super Star Destroyer from the Empire faction at action against the Pirates.
There are other smaller ships escorting the SSD. If you are curious about weapons, speed and system, at this game, everything must be researched and improved, by this reason, in the first stages from a campaign, the speed from the big ships is slow and the weapons are not so powerful as they can be after a lot more of research.
However, the SSD is enough powerful for destroy the pirate ships without problems and the battle is fun.
