The Woden is a 1996, Earth-launched, atomic powered ship that by every visual cue is indistinct from the Botany Bay. Arguably the first is of a similar level of technology but we can tell almost nothing of its shape. The second, since it uses the exact same footage as that of a 1996 ship and we are told Zefram Cochrane died/was lost 150 years pre-TOS at the age of 87, ie was born 237 years pre-2265 in 2028, Earth could not have had warp drive in 1996. So Botany Bay, and Woden, could not have warp drive. Which means those ships should not have nacelles. And even if you want to say Woden somehow should be of the same technology level as Enterprise, you are left with the fact it looks identical to Botany Bay. If it was some heretofore unseen ship without nacelles, you’d have a point. But we know what ships like Woden are because we have been shown them before and told what they are.
