The STF-1 is the first of a new class of tanks, the Super Tank Fortress, with the suffix "Fortress" referring to the new class's emphasis on heavy weaponry, massive size, and nearly impenetrable armor. These tanks are fueled by micro fusion reactors, with powerful engines driving the huge vehicles.

The STF-1 Warspite class is a giant, atomic powered tank designed to be used against vehicles similar to the unidentified Object ST1833, which was defeated by nuclear weapons after it arrived on the mainland, and nearly annihilated our armed forces. Built using reverse-engineered technology from the remains of Object ST1833, the STF-1 was constructed using the basic layout of a old super heavy tank design, with the end result being almost three times larger then the original tank. It's main armament is a newly developed railgun, with was previously too large to fit onto any existing vehicle. Thanks to this, the tank is nearly dead silent whem firing, and produces no muzzle flash. Another feature is its Micro Fusion Reactor, another piece of new technology that was also unable to be fitted into any vehicle, until the STF-1 was created. This results in the tank having an unlimited range, which combined with it's tremendous speed over land, leads to an ultimate weapon, from which no enemy of the Stratocracy of Skypark is safe.
