The Crossbow is an interesting design for two reasons, because it reminds me on two other designs: the Longbow-class Battlecruiser (similar name too, go figure), which also has horizontal pylons, and the Decatur/Belknap-class Strike Cruiser, who share similar registry numbers, and also have their pylons and nacelles below the saucer section.
The Crossbow is an interesting design, and takes a design approach
The interesting, (and unfortunate) thing here is that the Geonese shares her registry with an Ascension-class Dreadnaught (a sub-class of the Belknap), the Minsk.
In order to assume the existence of the Crossbow and the Geonese, I'd have to overlook the Minsk, and I'd have to assume that the Crossbow has a registry that isn't shared by the Decatur, Belknap, Ascension, or any of the Belknap's variants, such as the Raan. I'm usually willing to overlook the existence of one insignificant ship to acknowledge of another design.
And like I said, the Crossbow is nice, well modeled, and unique design.
By the way, are those holes in between the impulse drives and in the front rim of the saucer torpedo tubes?
