The Thor-Class Battle Cruiser was originally an assault cruiser, similar to the Gungnir-Class. After the first prototype, the designers decided that the Thor would never work as a standard assault craft, so they chose to change it to something like a long range bombardment weapon. The Thor now carries four anti-fighter turrets, and the VHX-1 'Mjolnir' (yes, that is spelt right) Heavy Zeon Beam Weapon (VHX1HZBW for short). The Mjolnir cannon is the largest and most powerful weapon ever mounted to a ship of the Thor's size (In fact, the Mjolnir is second only to the armaments of the Armageddon-Class, the largest and most powerful warcraft ever constructed). The Mjolnir is surrounded by two FL-6 'Megingjord' Zeon Reactors with the sole purpose of charging and firing the Mjolnir (The Thor has another Megingjord for other systems). LRAD stands for Long-Range Attack/Defense.
The same engine type as the Gungnir's.
Yeah, I cheated. The Bridge is actually slag from a Mega-Bloks clip.
To help you build it. The Mjolnir is built with a special technique that I love to use.
