The Pirates of Orion cover the entire Alpha Octant, but by the time of the General War, few of them were actually Orions. Orion originally joined the Federation as an ally during the First Romulan War. Because the Federation needed Orion technology, ships, and shipyards, the Federation made a deal that gave the Orion province special autonomy. Among other things, this meant that the Orions (not the Federation) enforced Federation law inside Orion space. Pirate organizations based on Orion took advantage of this, becoming the headquarters of a far-reaching criminal operation including piracy, smuggling, and creating illegal mining colonies on unclaimed planets. The territory of the Federation, Klingons, Romulans, Gorns, Kzintis, Lyrans, and Hydrans was overlayed by a network of fiercely independent criminal cartels. A crimelord led each cartel, and leased parts of his area to individual pirates as franchises for various criminal operations. One pirate might lease an area in which he had the sole right to attack merchant ships, while another pirate might get the franchise for all smuggling into and out of the Rigelian system. Each of these minor pirates was supported by the cartel network which bought stolen or smuggled goods, repaired damaged ships, bought and sold captured freighters, and traded in intelligence information on shipping schedules and police patrols. Most of the independent ship captains operating piracy franchises used light raiders or raider cruisers; the cartel itself maintained heavy cruisers which it used as enforcers to deal with those who poached without a franchise or failed to pay their franchise fees.
Orion ships are designed to avoid detection, being basically flat with angled hull plates to scatter any scanner beam that touches them. Internal volume is half as much as a regular warship of the same class, but this comes at the cost of miniaturized systems, high maintenance costs, and a distinct lack of crew comfort. The hexagonal structures on the wings are passive sensors which detect scanner beams at long range (before the ship doing the scanning can detect anything) and will then rotate the ship to be edge-on to the scanning ship, allowing it to evade detection while on its way to raid, smuggle, or illegally mine something.
Built as an enforcer able to handle larger pirate ships such as Battle Raiders, the Battlecruiser was a stretched Heavy Cruiser with more power, weapons, and systems. The first such ship built was named Song of Orion. It can land on planets using its wings as airfoils or its tractor beams for gravity landing. It has stealth and could possibly have a cloak.
The ship is available in a variety of materials. (Smooth Fine Detail Plastic makes an excellent cloaked ship!) Ships are unpainted, use standard flight stands available from many sources, and, while designed for gaming, make fine display pieces.
