Since previous posts seem to ask for a clarification...
You should see the carbon scoring on the corsair guns, its not easy blasting them off their fighters:D...
The SF has no policy on weapons, they can be bought sold and aquired from several means from black market, to salvage, to simply capturing one and reengineering the design. You'll see several SF bearing nomad weapons, does that makes us allied with nomads? No, it means we blasted them off their vessels and reengineered the design.
The SF does limit ship designs since those designs would be substatially harder to come by. (Hard to put together a vessel with big chunks of it melted away or missing, Junkers could since they would have several different copies to work with, all with different holes).
