This unit is created by upgrading the Xiron Medium Cruiser with the Xiron Force Coil.
The Xiron Heavy Cruiser has double the firepower of its predecessor unit, the Xiron Medium Cruiser. The addition of the Force Coil makes its energy projectors more potent and allows a quicker cycle time, and its defensive screens are greatly augmented. Furthermore, its speed is increased . . . without any loss in carrying capacity.
