In the past, I’ve spent a bit of time wondering why an Excelsior model was used for the 1701-B. I thought it was a budget thing, but it never felt like the Enterprise to me. But today I realized something I hadn’t considered. The six Enterprises versions were on the wall of the 1701-D’s observation lounge. That TNG set with its starship wall feature was built several years before the Enterprise B made its first and only appearance in Generations in 1994. Whoever designed that wall feature must have arbitrarily used an Excelsior Class design – most likely because there weren’t a lot of other options available in 1987.
