The Frax were an ADB experiment to see what ships designed with wet naval vessel firing arcs would operate like in SFB. Basically lots of phaser firepower in FX arcs and reasonable in the AX arcs, poor turning circles, etc. Other weapons are Disrupters and Drones. The weapons to power source ratio is higher than usual. Shields are good. Their ships have no Lab boxes, being purely warships.
The Frax have no culture, home world, empire, etc. because they're meant to be an experimental test ship design concept.
Frax comes from the firing arcs FX & RX weapons firing arcs.
The ship selection consists of:
DN Dreadnaught
CA Heavy Cruiser
CW War Cruiser
CWV War Carrier
DW War Destroyer
DWD Mine Sweeper (War Destroyer Variant)
FF Fleet Frigate.
The SSDs suggests a tubular or boat shaped hull with a curved pointed bow with hull mounted warp nacelles, so not much in the way of difficult 3D modelling involved. I'll create these using the M6 V2 3D modelling tool (which is dedicated to the SFC 1 & SFC 2 games).
