XTT-400

The Xeitial Tielatier Teinek 400 or XTT-400 (English: Experimental Heavy Tank 400) was a Valeric Heavy Tank Prototype that would see use in the Later part of World War II as the need for vehicles increased.

Development
The XTT-400 was commissioned as a test bed of a Multi-turreted tank, as well as the possibility of mounting a 200mm cannon on a tank, as to do multiple experiments at once on it. As such multiple designs were put forth, though only documents on the XTT-400 remain. The tank was developed with the XHVKT-1 in mind or the Experimental High Velocity Tank Cannon, a large cannon based upon smaller naval guns. It also mounted an experimental 90mm cannon in a seperate turret as another test bed, however many turrets were used in the development, though it was consistently armed the turrets varied widely.

History
The XTT-400 was used to experiment on many things, Large Tanks, Multi Turret tanks and large caliber cannons at the Facility Aurora a large hidden facility where many experiments were based during the Interwar Period. During these tests four were produced, each was used in Test Maneuvers to experiment with tactics for multi-turret tank companies, however the concept was given up on. They were then stored in a warehouse for 12 years until the war began to turn in the favor of the allies in World War II as such they were taken out and sent to frontline use, as the 200mm Experimental Gun did prove useful against tanks. The tanks were not able to however stand against more modern tanks, and all were lost by the end of the war.
