Accounting for an estimated 46% of all registered JumpShips in the Inner Sphere[12][15] (as reported in both 3025 and 3055), the popular, cost-efficient, and widespread Invader class is the archetypal JumpShip. Despite its martial name, it is a civilian design and ill-suited for combat. Though a crew as small as 12 can operate the vessel at reduced capacities, the bridge has stations for up to 20 individuals. This allows the crew to coordinate with up to ten transmission stations, monitor four ground-based battles, or monitor entire space battles as needed,[12] making it an ideal vessel to coordinate a task force.[8]

In 3055, it was reported that 51% of all Inner Sphere Invaders are operated by various militaries, 32% are owned by interstellar corporations, and the remaining 17% are owned by Mercenary units or private citizens.[9][15]

The Invader's most distinctive design feature is a pair of hydroponic garden domes. They produce food and oxygen for the crew, even a small surplus for trade with docking DropShips. Although fully automated in nearly 70% of the vessels in existence,[12] system failures mean that the gardens have to be maintained manually by the crew on every third ship. Many older ships also have a design flaw that could cause the hydroponics booms to lock in the extended position, preventing the vessel from jumping; this flaw was largely rectified following the Fourth Succession War and old ships were refitted accordingly.

Inner Sphere militaries bought most of the Invaders of the Clan War era and most of the Clans' transport fleets were comprised of Invaders[8] though it is unknown if they were Clan or Star League built vessels.


The original design of the Invader was not armed, but carried two special anti-meteor long-range lasers. Maintenance problems saw these replaced with a pair of Large Lasers or PPCs, but even these can barely match the firepower of a single aerospace fighter. This, and the thin armor, has led to Invaders being regarded as noncombatants, like all JumpShips in the age of LosTech.


The Invader also has two hangar doors in one bay for Small Craft and two cargo bays with an access door each (see apocryphal errors below).


  • Bay 1: Cargo (287.5 tons), 1 Door
  • Bay 2: Small Craft (2), 2 Doors
  • Bay 3: Cargo (288 tons), 1 Door

PPC Variant[8]

  • Bay 1: Cargo (285.5 tons), 1 Door
  • Bay 2: Small Craft (2), 2 Doors
  • Bay 3: Cargo (286 tons), 1 Door

Variants and Apocryphal Errors[edit]

Although no major variants are known, there are significant differences among the various sources describing the Invader owing to the inconsistent, contradictory, and often erroneous application of different rulesets at different times. For example, in addition to the cargo errors noted above, older sources sometimes listed the ship at 145,000 tons with identical stats otherwise. The tonnage of the ship was likely increased in later rulesets to keep it rules-compliant.

The Invader's hydroponics domes are not listed as a discrete component, but it can perhaps be assumed that they are integral to the vessel's overall structure.

The Invader was stated as being able to carry somewhere between 1000 (with 1 cargo door),[9] and 522-526 tons of cargo in the cargo section, depending on the weapon configuration. However, this is inaccurate under the current construction rules, which leave the Invader with only about 40 tons of dedicated cargo. This discrepancy may be viewed as a legacy error from earlier rulesets when JumpShip construction rules were not yet fully fleshed out, if at all.


  • In German products, the unit's proper name was translated to the Latin loan word Invasor.
