The S2B370 Brigand pattern of interceptor starfighters dating back some thousands of years ago. The designer of the craft is obscured from history, as is it's original manufactures, but however several firms started producing them. Clocking in at 110 MGLT, it's speed was impressive back then although it doesn't hold up to most modern interceptors. Still, it's maneuverability is impressive.
The most remarkable thing about the craft is it's twin-fuselage design, which really is far from a standard design choice in the present day. That isn't to say that the Brigand isn't a well-designed vessel, it's performance is equal to the Light X-Wing, although it doesn't have as potent of a hyperdrive, and is missing two light laser cannons.
Back in it's time, Brigands managed to find it's way in the hands of some pirates, and other racers. These ships are not in active use at the moment, although they can be found as collectable antiques by enthusiasts, collectors, or museums. People still might see them at air shows as well. Although enterprising pirates might have gotten their hands on the design schemetics, and produce them in an improvised and crude manner.
Restricted. As a starfighter, and this craft is subject to extra licensing requirements and increased scrutiny by authorities.
