Medusa System Defense Boat

design by John Macpherson

In keeping with the mythological nomenclature for SDBs, this ship class has been named Medusa because the "gaze" of its spinal PAW disables vessels without fiber-optic computers. The ship is intended for customs and system defense work. The PAW is not really intended as a serious combat weapon, but for disabling ships that do not respond to communications without having to destroy them. The Medusa carries a squad of Marines and 2 Virus specialists which can then ferry across to the target vessel to inspect it. The Marines and Virus specialists can also be used to inspect incoming trading vessels that may be harboring Virus or carrying more mundane contraband.

The ship is by no means a mere customs cutter. It carries 10 powerful 650Mj X-Ray laser barbettes. Each one does nearly as much damage as a blast from a 200 kiloton detonation laser and at short range can cut through the armor of even battleships. The ship is also well defended by a 120AV which will limit the damage from turret lasers to only minor hits. The Medusa's 6 sandcasters provide even further protection.

It was decided that the Medusa should be as large as the design specs would allow so as to conserve on the valuable relic technology used in its construction. The relic sensors provide the ship with excellent coverage; the relic computer is necessary for the use of the sensors and reduces the required crew. The backup TL-12 computer is fiber optic so that the Medusa does not become a victim of its own ploy. The launch is likewise equipped with a fiberoptic computer.
