The beam cannons wont be super powerful. here's how its going to work.
Terran Capital ships wont have beam cannons. They will have Torpedo launchers that fire missiles slightly less powerful then Cyclops torpedoes at enemy ships, but firing them quite fast.
Vasudan ships fire 'Tachyon Lasers', like a burst beam cannon that does quite high damage.
The new fighters will come in 6 classes : -
Space Superiority (We're calling them "Expedition Fighters")
Interceptor
Heavy Assault (We're calling them "Attack Fighters")
Strike bomber
Heavy bomber
Gunship (The Ursas bigger, meaner brother with a prison record)
There will also be Vasudan variants for all, except gunship.
There will be no cruisers. (In the storyline, gunships have replaced cruisers in firepower, so they are more maneuverable ,more powerful in their wings of 3 and when destroyed, the loss of life and equipment is not so great.)
Corvettes, Destroyers and Dreadnaughts (Think 'big destroyer', but not as big as Colossus). There will definately be a place and purpose for all types of fighters in various missions, including capture, escort, rescue, search and destroy, and fleet assaults.
The main highlight will be the weaponry though (To suit the campaign name, Destruction). Especially the Subspace Cannon.
Also, regarding the top speed, the highest speed will be interceptors reaching a maximum of 200 , thats with afterburners. To balance out the extreme high tech of GTVA ships, the enemy will have a few tricks of their own.
Expect to be surprised, and go 'WHAT THE HELL WAS THAT ?!" , when it happens.
