Snow Cruiser

Snow Cruisers were large amphibious warships (in the literal sense) designed specifically to cross the impassible frozen wasteland of the Crystal Sea. They represented the bleeding edge of Ragnite technology, being equipped with a high-output reactor of classified design, and propelled themselves using a combination of auger drive and two sets of enormous chainsaw-like treads at the front of the vehicle.

They were developed in secret by the Edinburgh Navy, with technological support from the United States of Vinland. Three such vessels, Comet, Centurion and Cavalier, were available at the time of Operation Cygnus, and all three participated in the operation to some degree. They were collectively referred to as the Cygnus Fleet.
