Well, when will someone make this ship? lol. Seriously this ship rocks!
For the Vorcha issue, Starship Spotter says...
"Some aspects of the Vor'cha class design reflect Starfleet technologies exchanged during the years of détente. The Starfleet influence can be seen in the Bussard collectors mounted on the forward ends of the nacelles. However, these collectors are supplemental to the ram intakes on the wings."
