Actually, I think this ship makes much better sense then the Scimatar in Nemisis.  What I mean is B & B should have had ships like these (like a Squadron of them) guarding the Scimatar.  The Scimatar I thought was just way too powerful and maneuverable for a ship that size.  
B & B should have made the Scimatar a slow moving, sluggish ship for its size, but had the supper weapon mentioned and had some armaments.  The Remans would have a Squadron of these guarding the ship (say maybe 5 of them or something).  
Oh, and very neat design.
