T2 categories are rolled into their bases (e.g. Interceptor into Frigate) except for these:
Orca, Porpoise, Rorqual
Nestor, BLOPs and Marauders are separated from other BS (significalty different masses)
Bowhead (it has weird mass relative to other freighters + C729 relationship)
Zephyr (Prototype Exploration Ship) also has weird mass relative to other shuttles
