Wyvern-Class System Defense Boat

design by Lewis Roberts

The Wyvern SDB was designed to provide a formidable defender of Imperial Naval assets. The Wyvern is designed to intercept and destroy enemy targets long before they get near friendly assets. The boat has 6Gs of acceleration which should allow it to close with hostile targets and to dictate where the fight takes place. It is armed with a power battery of laser weapons. These are linked together and focus a terrific amount of energy on a single target. To defend against attacks, the Wyvern is equipped with a decent amount of armor, more was desired, but the weight of the extra armor, drastically increased the amount of thrust required of the Heplar plant and drove the cost up. In addition to armor, the Wyvern is equipped with 5 state of the art sandcasters, to protect against PAWS, Lasers and Missile blasts. It also mounts 10 half ton point defense lasers, which can shoot down incoming missiles or fighters and at short range can do as much damage as the standard TL-15 150 MJ laser turret. It also mounts a very large Meson screen, which should neutralize meson guns of all but the largest ships. It also has a standard EMM system and 600 decoys to prevent target lock ons. To further decrease the chance of enemy ships locking on to the Wyvern, it is equipped with a 300,000km EMS jammer and a 180,00km Area Jammer.

The Wyvern is equipped with 300,000km meson communicator, which allows it to keep in constant contact with its base, even while lurking in a gas giant.

The Wyvern doesn't carry sick bays, or shops. It is expected that the naval installation which the Wyvern is assigned to can provide these faciliites. The Wyvern has a small 10 ton hangar, to accomadate small crafts carrying crew replacments, cargo and other supplies. The standard procedure is to base the small craft out of the Naval base.

The Wyvern is a very sleek and stream-lined design. It is formed from a central disk and two smaller disks, which are mounted to each side of the central disk. The large 100 Ton laser bay is mounted on the bow of the central disk. Four PD lasers are mounted on each wing disk and two are mounted on the central disk.
