Developed as a merchantman to ply potentially hostile Periphery shipping lanes, the Carrack-class military transport was developed from the SLDF Carrack-class transport and serves in the fleets of nearly every Clan. Unlike the Star League-era vessel, the Clan Carrack lacks improved heavier, more advanced armor and a Lithium-Fusion Battery.

While no examples of the class were known to remain in the Inner Sphere, an undetermined number accompanied the Exodus Fleet, with the modern Clan Carrack military transport first entering service in 2950. ComStar analysts have been unable to determine how many of the Carracks which are currently in service among the various Clan toumans are upgraded Star League era vessels and how many are new, Clan-built ships.


Due to its role as a military transport, the Carrack features a light array of mixed capital class and anti-fighter weaponry. The nose bay and each broadside feature a pair of NL35s and a single NAC/20, two ER Large Lasers and four Large Pulse Lasers, rounded off by four Anti-Missile Systems for point defense. Save for downgrading the Naval Autocannon to a NAC/10, each fore and rear angle as well as directly aft features almost the same layout as well.


The Carrack's 63,446 ton cargo hold surrounds the vessel’s Compact Kearny-Fuchida Drive core and is flanked in turn by two Small Craft bays. These bays frequently house a pair of aerospace fighters and a pair of shuttlecraft, however the exact composition of the small craft complement appears to depend on each individual vessel’s captain.


  • Clan Merchant Caste 
    Both Clan Nova Cat and Clan Diamond Shark faced the same dilemma when assigning Carrack-class vessels to their more affluent merchant castes: whether or not to give their merchants war materiel on par with that of the warrior caste. Working together the two Clans decided to circumvent the issue by stripping many Carrack-class vessels of capital weapons and heavy armor, while at the same time maximizing cargo capacity. Like the basic Clan models, these merchant-caste variants also lack Lithium-Fusion Batteries and advanced armor composites, but they do feature the Clans' HarJel-based Hull Sealant technology.

  • Fighter Carrier 
    at least one Carrack, the Pretoria Castle, was converted into a fighter carrier capable of transporting a wing of aerospace fighters.[6] To date, not record sheet or formal variant for this modified version of the Carrack has been released.
