"Prepare to fire,"
Imperium Orbital Operations have been considered a usable weapon/defense since the end of the Corporate War. A constant problem that occurs is if your fleet is busy trying to destory the atrox or some wild band of pirates and somebody is attacking a nearby planet, does one have to stop everything and go protect the Planet? No, you provide a Orbital defense network capable of filling in for fleets of ships.
Orbital Weapons for Offensive Purposes[]
Orbital Rail Guns: are used to puncture through indiviual structures as well as creating massive craters which disrupt the battlefield terrain.
Orbital Ion Cannons: The best shield shutdown weaponary in existance. Bases shields down in seconds and unshield structures become victem to the Proton cannons.
Orbital Proton Cannon: are used to destroy wide scale areas a single strike. A constant worry is the chain reaction would becomes self sustaining destroying everything on the planets surface until it begins affecting the mantle and the core.
Orbital weapons for Defensive Purposes[]
Orbital Rail Guns: unshielded ships are history with powerful warp 9 velocities a cartridge about a foot wide is able to pierce and distort most any ships armour.
Orbital Ion cannons: Shields are stripped from ships and fleets, but who would have guessed that they made such powerful phaser like weapons as well.
Orbital Proton Cannons: Do you really want a weapon that will strip the bonds of matter from the atoms and cause a chain reaction that can destroy entire fleets? My answer, Buy this baby!
