We don't know the specs yet, but imo the PC Mk II should have:
- 1200+ tonnes / units max cargo.
- Same or longer than a Beluga Liner
- Same or wider than a Type-9.
- FSD SCO optimized
- Class 8 power distributor
- Class 8 thrusters
- Fighter Hangar support
... and if only a handful of ships can mass lock it, the MK2 won't be as vulnerable as people think.
