In the 2470s, the United Earth Peace Corps was at a state of war with LUNAR, the colonies on the moon. The forces of Earth, it is said, would stop at nothing to crush the resistance forces that defied total rule of the Earth and engendered dissent on the earth against the 'benevolent' rule of the unified government.
Many, many conventional weapons were developed to aid in the proposed invasion of the lunar surface, but hardly anyone knew of the /unconventional/ efforts of the UEPC to conquer the moon. Nuclear and Kinetic bombardments were out of the question since the Moon had anti-space capability and would just thwart the attempt by shooting down the projectiles. What hardly anyone knew were the existence of other super-destructive weapons that were largely forgotten since the Third World War.
It was during that destructive period that a leading high-energy scientist, dismayed and jaded, conjured up a theory which would produce highly unstable energy in a coherent form. As it could not produce any lasting energy and it was impossible to store, it had no application for a power source but could be capable as a weapon. It was never developed during the Third World War, as more resources went to conventional weapons. The UEPC re-discovered the formula however, and sought to put it into some kind of active deployment.
Very little of this hypothetical project reached the public eye. A massive project was proposed to the United Earth senate for a "Construction complex" allegedly designed as a super-crane. The disappearance of several leading physicists was reported over the span of nine years, and it is thought the crackdown at Palifca also had something to do with what conspiracy theorists call "The Big Gun".
According to rumors and popular conspiracy theory, the massive platform was designed to be a mobile fortress. Armed with a pair of these high-energy bombardment cannons, it would roam across a continent and re-position itself to prevent counter-battery fire from the moon. It would fire bolts from earth at the moon, and these bolts of pure energy (in a vacuum) would make craters on the moon the size of newfoundland island. As they were pure energy they would be impossible to intercept. Initially it was supposed to have many significant self-defense batteries as well, but cost and weight cuts diminished the arsenal down to four experimental particle beam cannons- each capable of vaporizing a city block. Had it been deployed, it would have been accompanied by a Battalion of Axels for close defense purposes.
It is debatable whether such a weapons platform was even possible, let alone constructed. Then, as now, true tall-scale "mecha" were largely ornamental and hardly practical given the realities of conventional warfare. Power concerns were another problem as well, and it's thought the unit would have to be connected to a local power grid in order to charge and fire its main weapons. Then again, like the ancient Bombard cannons and the super tanks of the second World War, such massive weapons platforms have been deployed in the past.
Popular rumor calls this monster weapon the M1 Augudis, and it would have been constructed in San Francisco in the American Continent. Although such a massive weapon would be obvious to spot during construction, it is suspected that the mecha was actually assembled underwater in the bay itself. The fact that the SF Bay was the site of a massive 'excavation project' for ruins from the Third World War has kept this rumor alive. It is still unclear if this monster was constructed, or its current whereabouts. Ironic given a machine so big.
(Drawn up for the MechaDesigner's contest challenge #2: The one that shouldn't exist. It's been a while since I visited the Agitator universe as well, so I decided that the UEPC would be flexing it's WORLD DOMINATION muscles in doing something crazy. And yes, it's a homage to another design of mine... I figured I'd work it into the Axel saga since somehow the ARX machines got in there too *shrug*
By the way in case it wasn't clear, that little smidge between my signature and the M1's right foot is a KR-14A. The line next to that is a person).
