Operational profile

Recognition and use

The Marathon is a twelve-hundred-ton assault cruiser with Jump-2 range, four-gravity acceleration, eight points of armor, protected systems, and four particle-beam barbettes. Twelve beam lasers, six missile racks, six sandcasters, and twelve point-defense lasers provide broad fire support and protection.

A cargo boat, two armed transports, multiple armories, medical facilities, and a 193.9-ton hold let its thirty-six-person crew deliver personnel and equipment under fire. It combines transport capacity with serious combat power, at the cost of a large military operating budget.
