Chairman class battlecruiser
The Sirius Trade Federation
Back to the Starships and Spacecraft contents

The Chairman class battlecruiser makes up the total battlecruiser force of the Sirius Trade Federation. A total of eight are currently in service with a further eight examples on order. The ships main armament, a 12,000Mj spinal particle accelerator is somewhat more powerful than that fitted to the United Worlds Commonwealth Europa class battleships but like other battlecruisers the ships armour is light, and the Chairmans are not intended to face such opponants.

The batteries of 40Mj lasers are primarily used in the missile defence role and when linked via their MFD systems have a good chance of hitting a missile well outside the missiles detonation range.
