The Behemoth (Self-Propelled Gun)

Description
The largest self-propelled gun ever built in the known universe is a Machina (Benvora clan) weapon known as the "Behemoth". The Behemoth looks like a huge cannon mounted between two Elephant (the vehicle)-sized sets of tracks, with a crane behind the gun for lifting shells into the breach. The vehicle has a total length of 100 meters. The gun itself is a 1200mm light MAC capable of pounding both ground and space targets. Even at the lower power settings for attacking ground targets, it's impact created a blast equal to that of an ENTHROPY massive fuel-air bomb.

Operational History
It was built by a group of several Benvora-clan workshops in a manner similar to the construction of a Machina warship. Though the Behemoth proved itself a force to be reckoned with, pounding Remnant and Necros fortifications into dust and providing ground based anti-spacecraft defense of the planet of Kastellia, it was horribly weak against aircraft, being a large target with a maximum speed of under two kilometers per hour. The Behemoth was destroyed during the failed Necros assault on Kastellia, when it was bombed by Necros Bombers and Carrion Gunships.
