I was under the impression that this was late tmp, hence the extra phaser designs and the advanced engines.
Nothing advanced about those engines. Granted, because of the intercooler grille texture being the same as those from the Indomitable, you can be mistaken, but look at the design of the engines. They're upscaled versions of the Refit Connie engines, beefed up too.
The phasers were a unique design that GAFY came up with on his own that I really loved. To help set this ship apart from other Mars classes out there, and to further enhance the feel that this was the first of her kind, a prototype if you will.
I built this bash the way I did because, as much as I love WZ's Mars Refit, I wanted something more traditional, that was reminiscent of earlier times in Trek. Using many of the same components as the Refit Connie during early TMP, I felt that this bash accomplished just that.
I wanted new clothes for this lady, and GAFY provided them nicely. These textures were the basis for those Connie retextures he did.
I might include an alternate set of textures with more traditional phasers and engine glows. Haven't decided yet.
Should be noted that this ship, unlike the Connie retextures, is meant to be in the standard Trek timeline. However, if I include the alternate textures, this ship could fit into both timelines easily.
I'll think about it.
