I may not know much about warp theory, but I do know the Nebula Class looks ridiculous.
Imagine the TNG opening but with the Nebula Class Enterprise D zooming across and also the theme is played on a tuba.
Wasn’t the inspiration for this also the Northrop Grumman E-2 Hawkeye since they’re meant to be science craft with large sensor arrays?
Found it. The AWACS.

The design upgrades for the Nebula-class were done by Mike Okuda and Rick Sternbach and the model was built by Greg Jein. In Drexler’s blog, Okuda elaborated further: "As so often happens with this kind of project, we didn’t give Greg enough time to accomplish this, so we decided to retain the original scale of the Galaxy-class ship saucer. I suggested the original ‘AWACS’ pod in response to a producer’s observation that the ship might otherwise appear unbalanced. Unfortunately, the AWACS pod didn’t look as elegant as we had hoped in “The Wounded”.
