The Corvus Crab (Extra Heavy Assault Class)

Stats:
Armour:50000
Mass:40000kg
Cargo:25 cu
Volume as Cargo: 500cu (this stat doesn't matter much by this point)
Weapons: 2 small and 2 large
Max Turbo Speed: 180 m/s
Turbo Energy: 55/s

You get the drill. This one is based on a scaled down version of the Helman K-27 Overseer. Moth like powerful thrust will be needed, and manueverability will be like a Ragnarok Mklll

This ship is a new class in itself. It has more that double the armour of the next most armoured ship, and double the weapons. It will take a seriously long time to kill, like it's Hive counterpart. It will create a new gameplay style of hard to get, hard to kill ships. Fights between two of these would be spectacular, to say the least. These advantages will be offset again by how it is acquired. It is manufactured, and the manufacturing mission is unlocked only at high license levels and high Corvus standing. Maybe an additional mission to the Hive Research mission tree as well.
Again, an advantage is that the devs will not have to draw up any new ship designs. I'm not downplaying the effort involved. I'm only writing what I think might be an easing factor.

This suggestion has been posted after Whistler and We all float cited my earlier suggestions as a violation of Rule #5.
