A Mongoose 2e design. The J6 Hercules-Class Merchant Tender is a civilian version of the Warmonger-Class Battle Tender build and run by the Achenaar Antilles Line in the Core sector. It has no jump fuel storage and is fed by special stations out beyond the jump limit (this is an external variant of the drop tank) that can feed it all the required fuel (3,300,000 tons) in six minutes so it can jump.
Their network of stations support this and lesser companies cannot match the amount of cargo they carry or the distance they can deliver it. This is an advantage they hold over their rivals. The vessel is designed to haul a mixture of 89 Type V 50,000-Ton cargo, fuel, low berth, and passenger pods (4,450,000 tons total). At need, it can also carry Type V 50,000-Ton Marine Transport pods and Navy Passenger Pods under contract.
The Hercules line was designed with quick turnover in mind. Each stop should only run 72 hours, at most, if the system crew is on the ball. If they aren't, heads will surly roll as the schedule for these ships is everything. As the crew will be worked hard, even with robots doing most of the work, they are treated very well, with individual staterooms, a gourmet kitchen, and a hot tub big enough for everyone. A robotic steward sees to their needs and keeps morale high.
