The Invader is the most common JumpShip operating in the Successor States. Designed to transport up to three DropShips, the cargo capacity of close to 1000 tons. Its availability and efficient design make it well-suited for both commercial operations and for large mercenary units. The Invader is also the JumpShip most commonly used by the regular armies of the Successor States.

An Invader masses roughly 152,000 tons and is 505 meters long. When fully deployed, the ship’s jump sail is just over a kilometer wide. Its appearance is similar to the familiar needle-like shape of many other JumpShips. Measuring 65 meters in diameter and 6 meters wide, is the centrifugal grav deck providing artificial gravity for off-duty and visiting personnel.

The Invader’s most notable feature is the pair of large domes mounted on either side of the command section. These large structures contain hydroponic gardens that provide fresh food and oxygen for the ship’s crew and yield surplus large enough to supply its DropShips and provide for storage and future use. Plant care is fully automated in about 70% of the remaining Invaders, while the remaining 30% require crew members attend to daily maintenance.

Though the hydroponics take up most of the space for these domed constructions, a portion is reserved for a meteor defense system. Originally employing a special set of long-range lasers that required extensive maintenance protocols, most now carry either a pair of PPCs or a pair of standard Large Lasers, identical to those used by BattleMechs in the field. Although the radar systems on many Invaders can no longer easily identify objects as small as a meteor, the PPCs or lasers are still useful in repelling boarding efforts.

Another feature of these domes, is their decks are oriented differently from the rest of the ship’s decks. To alleviate problems that might occur when the ship is under acceleration, the domes are mounted on large traversing arms. Before the ship’s station-keeping drives are fired-up, these arms swivel outwards, aligning the domes so that the decks run perpendicular to the line of acceleration.

Deep within the Invader’s command section is a large bridge filled with communication consoles, electronic plotting boards, and video display panels. The bridge makes the Invader a good choice for coordinating major merchant ship operations and task force missions.

Though designed to be operated by a staff of twelve, the bridge has stations for up to twenty people. A person could operate many of the automated systems alone, though many of its capabilities would be greatly reduced. At full capabilities, the bridge can maintain simultaneous communications with up to ten transmitting stations, monitor up to four planet-based battles, unit movements or combat fronts, and monitor a full-scale space battle.

Because of the heavy mechanics involved in positioning the Invader’s domes, the systems regularly break-down. This can be a problem if the booms are extended, because the hyperspace field generated by the K-F drive cannot enclose these structures when extended. In such cases, there is a good chance (30%+) that the drive will fail to activate, and in addition, jumping with the domes extended might sheer them in half. To resolve these problems, most crews simply leave the domes in their retracted position.

When the domes are retracted, the meteor defense systems only cover the ship’s rear-side arcs. Also, while the energy collector sail is deployed, the ship cannot fire them without hitting the sail from this position.

Though no Succession State has any notable concentration of Invader-Class JumpShips, reliable estimates indicate that approximately 46% of all JumpShips within the Inner Sphere are Invaders. Of these, Successor State armies operate nearly 51%, merchants own 32%, and mercenary companies operating within the Inner Sphere own 17%.

The “Mordred” is an older vessel, but its exact date of construction is unknown. Acquired early in Excalibur Corporation’s history, as the “Thief of Three Worlds”, it fell into their hands under cloudy circumstances, but it believed to have been through forced absorption of a smaller, rival trade company, probably “Hyades Express Shipping”, whose entire merchant fleet disappeared during one jump.

However they had acquired it, the vessel was employed in the Excalibur Transport division for many years, hauling ores from its mining efforts in System – Cassandra towards the Inner Sphere. In late-3023, the vessel along with two paying private vessels and a third Excalibur-owned Danais-Class DropShip laden-down with ores, was captured by pirates. Rumors claim these pirates were actually its long-term adversaries * “The Iron Dingoes”, though this has yet to be substantiated.

In late-3024, the “Mordred” appeared under the aegis of * The Blood Raiders as their personal JumpShip. At present, it lacks any specifically assigned officers or engineers.
