Sadly the TPG Terradon frigate is not as of yet a player controllable ship, however it's little sibling the Trident type M is.

It looks to be a raptor prototype,i see it has a turret...i want it even more

No, it's not in any way a Raptor prototype; it was just designed by the same people. It's actually a small capital ship about the size of a Trident.
