Higher-grade hangars. A little more power and tonnage, but they can assemble extra SRVs like hangars.
Slightly larger hangars- like size 3 hangars of the same low grade, same power, extra ton, but extra SRV rebuilds. (If you have a size 3 slot with a size 2 hangar, you could get a size 3 and have a spare if you mess up.)
