I do believe you can, but you'll be hit by some kind of power plant nerf. How much I'm uncertain, but if they're allies, it may not be too bad.
EDIT: Assuming your an indy that is, if your in Order|, I'm sure they have there own guidelines. Most factions will only let senior members fly non-faction ships i.e. it's considered a special privilege in many cases.
As the Current Leader of the Hojo Clan (A Blood Dragon Unofficial faction that will try to apply for official in the future), I know that we, alongside the ]bd[ (or what remains as i understand) would at least like requests for our tech. inRP, we are limited on supply's as it is, but if you can supply good reason as to why they/we should let you, then I'm sure a deal can be reached. I look forward to your transmission
Don't need faction permission anymore but there is RP consequences. Isn't any BD faction atm anyways. Just guns. Their ships are prized family possessions maintained and inherited by the younger generation. Not only that GMG plays a major role in keeping those ships zero hour'd and flying so that the BD can continue their goals. Guns are easy to produce, shouldn't really be an issue, but the RP of the BD fleet itself has those ships pretty locked up for BD use. That being said Order is one of the very very few groups BD opened it's arms to and was instrumental in the design (although GMG did the funding and BD did the building) of the Kagutsuchi. Never know, many things are possible.
Oh wait, sorry, looks like there is a BD faction. Unofficial but still start up some RP with them. Get them involved. Disco needs a BD official faction.
