Superlaser:

The planet blasting super weapon of the Empire has been scaled back to a ship based form. Instead of needing a massive station to house this weapon, the more advanced superlaser can be mounted on vessels 3000 meters and above. Taking 4 rounds to charge, this massively powerful weapon is designed to target ships and planets. The weapon can target ships 1000 meters and larger. While it has enough power to destroy nearly any vessel it can not destroy a planet entirely. It can however do massive damage to the planets crust. This weapon can not hold a charge through hyperspace.

Planetary HV cannons:

The massive Hypervelocity cannon fires huge rounds of solid durasteel at near light speeds. These rounds slam into ships and their shields and can do massive damage. Ships 500 meters and larger can be targeted, and most would be obliterated. These come into battle loaded, and takes 3 rounds to reload. There can only be two of these huge weapons on metroplis worlds. They have enough power to reach high orbit.
