This mod replaces capital freighters with the Pegasus from Battlestar Galactic (BSG). You must have a capital freighter, not one of the system freighters.
If the hangar is in an odd place, please let me know in the comments along with the seed of your freighter so I can try to fix it.
This is based heavily on the work of the Star Trek Enterprise D Freighter mod by Mjjstral. Credit goes to them for figuring it out originally.
