Looks like something out of Flash Gordon(that's not necessarily a bad thing).
It also has bits that remind me of Russian nuke subs, so Coalition maybe? If you squared off the bridge section it would look like a civilian cap ship. The ridges on the nose look a lot like the ridges of the luxury and prison liners. Make it bigger than a gunboat and smaller than a cruiser and call it a civilian escort frigate.
Definitely NOT a BHG ship IMHO. If you want to make another BHG capital ship (Not that we need one more), try to make it look more like the existing BHG line of vessels.
If you look at the existing BHG line of vessels, such as the Manta VHF, the Bottlenose GS, the Thresher destroyer, the Bullhead Battlecruiser, and even the Mako Battleship, you can see they all share a general designphilosophy.
The model you presented, although nice, doesn't in any way fit into that design philosophy.
It looks more AI than anything else.
