The Dominion Fleet (DF) has only one ship of this size; the Honoured Star. This 2KM long vessel is absolutely lethal. If you see it, you won't see it again because...you're dead. She is armed with rotating dual heavy Plasma Cannons, stern heavy Plasma Blaster, and the most lethal weapon, it's Resonance Photon Cannon, capable of wiping out a planet in 2 seconds flat. She is also capable of launching 52 squadrons of 12 fighters from the hangar under the Bridge.
The reason for all of the power is that she was built over Dominious III in the Dominion system. This planet has extra rare materials necessary for this power.

The massive 1KM wide engine.
The minescule launch bay.
These were the last images transmitted by the Dakota Research Vessel before she was destroyed. (Last two photos).
Maybe you should make a V2.0 of this one, to improve some details, because it's already pretty good, with some nice SNOT. The overall shape is fine, I love the front in particular. BTW thanks for your comment !
