Ahh, the B-Wing! My favourite ship from the X-Wing games
Just some quick randomness:
There are many schools of thought on the S-Foils:
In the FILMS, they just fly vertically ( | ), and the wings just open out when it's in attack mode so that it's a sort of cross-shape.
In the GAMES, the S-Foils in the game had the ship flat ( --- ), and when you opened them, the whole ship would rotate 90degrees with the wings opening, so it would end up in the same vertical cross shape as in the FILM.
The pilot PoV in the games varied - The S-Foil opening in the older DOS games rotated the ship around the engine block and opened the wings. Later games rotated it around the cockpit. This is because in earlier games, the turning axis all went through the engine block (More 'realistic' movement, slightly weird to control), whereas in later games they went through the cockpit (Less 'realistic' but easier to control).
The cockpit position was fixed in all the games so that whole rotating-cockpit thing only did anything during S-Foil transition
In ALL the games (IIRC!), the missiles fired from the central pod from the side inlets (Not the 8 'vents', although I'm not 100% clear as it was pretty damned hard to tell TBH
Also IIRC, the B-Wing uses 4 fusion engines, similar to an X-Wing but better, to power itself according to the in-game tech documents. It has a repulsorlift, which I assume would do most of the work keeping one aloft inside a gravity well.
Like all unmodified Starwars fighters (Aside from the ridiculously over-powered Missile Boat), the B-Wing can only hold one type of projectile ordinance, and can only fire a maximum of two at once. It can hold 16 standard Proton Torpedos in total, 8 on each side bank.
It has 3 lasers and 3 ion cannons, but there's a lot of confusion as to where they go (It varies in all the games too!). It's supposed to be highly configurable anyway (Those Verpine and their Modular parts!) so just throw in 6 gun slots or something
