That's an interesting looking design but one might argue that it looks even more futuristic than the NX01. With some alterations, it could've been quite promising.
Before I found the pic again, I could have sworn that the ship looked much more like a naval vessel than what this picture shows. Obviously I remembered it that way because of the red underside.
The reason why I was trying to find the pic was because I'm in the process of creating a "revised" take on ENTERPRISE, with a much more logical course of events and a much more military take on the show. One of the issues I always had a problem with was the Earth Starfleet:
1. Where did they get their raw materials to build their spacecraft when 100 years ago there wasn't enough metal on Earth to build more than the Phoenix's cockpit? (And ENT made clear that the Vulcans did not help Humans with ship construction, nor did Earth have any trade agreements with other alien races).
2. Why did there seem to be so few ships in the Earth Starfleet when just the U.S. Navy alone has thousands upon thousands of ships?
3. Why, if all of Earth's nations are truly united, the crews of Earth Starfleet ships consisted of all Americans, with the exceptions of one Vulcan, one Denobulan, and one Brit? (despite her exotic-sounding name, I truly believe Hoshi Sato was just another American). Where were the Chinese? The Russians? The Middle Easterns? The Africans? The Vietnamese? The French? The Spanish? The Germans? The Jews? The (insert culture here)?
My take on the Earth Starfleet is a) they should have been named the United Earth Space Navy instead of "Starfleet," b) the ship designs should have been based on naval vessels, and surviving hulls from these ships should actually have been used in construction (i.e. the clear use of submarine hulls for the DY-class ships, etc.), and c) the names and registry numbers of the ships should have reflected their former lives (i.e. the Enterprise would have been based on the aircraft carrier, with a registry number of CVN-65-A or some such). I wanted the above design to reflect that as a starting point, because I thought it loooked more like an aircraft carrier with nacelles. But, alas, it doesn't.
