The Shuttle bay of most ships, are large, with enough space to park two DX-class Spirit Dropship, two Seraph-class Starfighters, or eight Type-26 "Banshee" Ground Support Aircraft. The Shuttle bay also has a 'Door', a force field that allows or disallows aircraft to enter, and also pressure shields. There are at least four Shuttle bays on a CCS-class battlecruiser. Larger vessels, such as assault carriers, possibly have 2 to 3 times that number of shuttle bays.
