From publisher blurb:
The goal of the ConFederation’s “Project Atlas” was to build a dropship for soldiers and mechs. The Meridian variant was the primary focus of the contract - a spherical “tail lander” designed to haul a lance of four massive combat mechs plus the personnel and supplies needed to maintain a forward base in support of the squad.
To recoup costs and expand market share two additional designs were spun off from Meridian and developed for the civilian sector. The first was the Europa-class freighter, which essentially emptied out the mech bays for cargo space and used the excess overhead to double up the pre-existing munitions deck for even more cargo.
The final variant - designated “Pangea” - filled the lower section of the spherical craft with cabins, suites, and dormitories for paying passengers. In both cases, the detachable upper dome section of the ship was left as is since it contained the control and support sections needed for every variant. All variants have cabins for six senior personnel and bunks for a dozen additional crew. The Pangea variant also adds beds for 46 passengers. All versions are at least lightly armed.
