At the time of the Une Conflict, plans called for five MDC-HEC00 Leviathan class transports, but only the first three were spaceworthy at the time the conflict broke wide open. While the Leviathan-1, Leviathan-2, and Leviathan-3 departed to rescue the fleeing Preventers, the Leviathan-4 and Leviathan-5 were still being constructed. The two Leviathans were going to be scrapped completely before Martian engineers saw the huge ships' potential as proper warships with some modifications. The changes were drawn up, and the two massive ships were redesignated as Behemoth class supercarriers.

Visually identical to the Leviathan at a glance, the Behemoth sacrifices nearly half of its cargo space to house a rounded armament consisting of large beam cannons mounted on turrets all over the main body, as well as several large missile tubes housed in the leading edges of the ship's wings. While not nearly as massive as the Venusian flagship Aphrodite, the Behemoth still retained enough hangar space to carry a sizeable mobile suit compliment, and with the addition of several launch catapaults on the ship's outer surface near the airlocks, the ship could launch its entire mobile suit force relatively rapidly, and provide considerable long-range punch against other warships, making the Behemoth a virtual flying fortress. The two Behemoths would serve as the mainstays of the Mars Defense Corps fleet during the Venusian conflict.
