Go to that moonraker page and you'll see he made a TMP version of the NCL (the Kearsarge) but not of the NCA - it's the same ship but with an extended rear hull, bigger impulse engines and a third nacelle below the new pseudo-secondary hull.
I think Nightstorm made something similar using Moonraker's NCL though it's not exact and since Eras of War is down I don't know where to get it now. I think someone put all those ships on the Starfleet Universe.
