Alliance are a serie of different mods. On the Star Wars GC, you can play the civil war Empire vs Rebel era + Black Sun and soon the Republic and CIS.
This will be the level 5 starbase from the Fel/Galactic Alliance faction.
This model was made few time ago by Warb_Null named Valor station and I added it to the mod as you can see with a new skin from Nawrocki. Have fun.
