IMI looks at their old tank designs and deem them all to heavy. They decide to take a new approach. Make a hull with no armor, add all of the proper equipment and then add as much armor until they hit 45 tons. The tank is made on the drawing board quickly and then the engineers start to make a prototype. The Mark X Basic Railgun is used as the main gun, though a mockup is used for the prototype.
