The carrying capacity of an orca means you'll be able to take the POS, POS modules and fuel, extra combat ships, modules, ammo, bpc's etc.
An extra hauler would be handy to allow for longer stay/resupply - and also for returning to K-Space.
Regarding tanking - the Orca should be able to tank the NPC's without a problem - but the bigger issue will be the new AI for the NPC's - they will be switching targets, using ECM on other ships, etc.. Gonna be interesting.
There is going to be a big unknown to start with regarding T3 - although I'm hoping DevBlogs and SISI will help full the gaps.
Those not involved in flying the supply ships would bring pure combat ships & mining vessels. All combat ships should initially fit something for scanning.
I would guess that all bar 1 scouts would deploy and look for WH's - and start mapping the current neighbours. The remaining scout would survey the moons in the system.
This would be a "hot op" so we'd be deciding things on the move about where to setup the POS initially.
I would guess also that combat ships would scout the system looking for NPC's with "We come in peace, Set Phasers on kill" painted to their hulls.
