Developed by Lockheed Galactic and manufactured in their shipyards in the Thorin system, the Leviathan class of JumpShips was the product of Lockheed Galactic being one of the very first manufacturers to quickly seize on the technological advances made by Blue Nose Interstellar Technologies. Lockheed Galactic paid a premium to Blue Nose for the rights to use those advances in their own products, recognizing that being able to carry DropShips through a jump was a huge advantage.[1]

Despite requiring a smaller crew than the Liberty, the Leviathan had twice the DropShip capacity and more than twice the total cargo capacity than its competitor, all of which it achieved for a price less than a third higher. The Leviathan was an ambitious design, and one that repaid Lockheed Galactic fabulously; it became their signature product, and allowed Lockheed to expand into dozens of systems.[1]

The Leviathan had a number of features that made it a popular vessel, as Lockheed Galactic made the comfort of crew and passengers a priority. With two 90-meter grav decks, one for use by the JumpShip crew and the other for use by the DropShip crews and passengers, the Leviathan was well-equipped; to make the class easy to maintain and repair, the design included spacious maintenance passageways and large access panels. The Leviathan was a hit with customers from the beginning of its entry into service, particularly when large transport companies found that they could transport both their own DropShips and additional "tramp" ships at the same time.[1]

Lockheed Galactic manufactured Leviathans for decades, but by the end of the Twenty-fifth century the same access panels and maintenance tunnels that made it popular with crews had proved so popular with pirates that the Leviathan had earned a reputation as an easy target for both being boarded or for being immobilized through damage to, or the destruction of, its large external fuel bunkers.[1]

Despite these problems the Leviathan remained in service for some time, although those ships used by governments or the military were generally modified to be more secure by sealing the more readily-accessible access points and the addition of quarters to allow them to carry marine detachments. Many ships used by corporations underwent similar modifications, but a century after the Leviathan first entered service it had largely been supplanted by the later Star Lord and similar large JumpShip designs, a fate hastened by the unsuitability of the Leviathan as a military transport during the Reunification War.[1]


The Leviathan was unarmed, but mounted 192.5 tons of standard armor, distributed evenly around the ship.[1]


Design Notes[edit]

  • The Leviathan used Prototype JumpShip Docking Collars.[1]
