No, I've read that it can't be removed at the shipwright. And (not to be too nerdy here), if that third nacelle was gone, you would also lose the lance. If you don't want the lance, then maybe the Galaxy-R is the ship for you instead?
The 3rd nacelle's canon. That's why it's even in the game. There wouldn't be much point to having a galaxy x shipo if it didn't look like the galaxy x from the show.
in the beguining, the option to remove the lance was there.
i use it because i didn't like the third nacelle at the beguining and also to deceived my opponent in pvp to make them bielieve they were facing a galaxy retrofit so they didn't try to get out of my fore firing arc.
the problem is that, like everything concerning the galaxy in this game, it was done in a very sloppy way and the light of the nacelles were "separated" from them.
and since they didn't care to fix it, they removed the option.
Mine is still new in the box and it says you can remove the 3rd nacelle. I am considering selling mine on evil bay. PAid about $45.00 when it 1st was released. Price has come up some. I have all the Art Asylum/Diamond Select Star trek ship collection, wich they made the C. It's the only missing Enterprise. Been hard not to open them up.
