The technology seems plausible, but somewhat beyond the capability of current human technology. Humans in this universe have only developed crude Alcubierre Drives. Manipulating gravity waves and sigularities is the cutting edge of human technology, and technologies such as the Warp Gun and the singularity engine are too advanced for the humans. The Vorqhul would probably have this sort of technology, and so I could justify developing a slightly-nerfed boundary system developed from captured Vorqhul ships.

In any case, the ship's concept and many of the technologies are reasonable for this universe.
[/quote]Alcubierre drives would require singularity manipulation, gravity manipulation and spatial manipulation anyways.

As a curious mention Star Trek Warp Drives also have almost nothing in common with Alcubierre aside from both warping space.
Ironically enough ST warp drives would be easier to make than Alcubierre ones, if they were actually a scientific possibility.
Granted, Alcubierre drives are almost just as implausible aside from the math at least checking in. It violates a bunch of physical laws to our understanding.

EDIT:
BTW, how large are the various ships here?
I can tone down a bunch of things if destroyer class ship at average smaller in this setting.
