Reichu: The Command Center is where most of Nerv's key personnel hang out and the MAGI super-computers are located. This image is part of a panning shot of the Tactical Command Room that will be used a lot in the series. According to production drawings, “Command Center” refers only to the top tier of this structure, whereas the whole thing is called the “Command Tower” — but we can't hope for that kind of consistency in the script.
Shin-Seiki: The Command Center bears a rather blatant resemblance to the forward superstructure of a WWII-era battleship; hence the fact that it is often refered to as “the bridge”, and its denizens as “the bridge crew”, or even “the bridge bunnies”. I can't think of a good, “realistic” reason for the Command Center to be designed this way. As with so much in NGE, it's just there to look cool.
Reichu: It's probably just because Anno is a big fan of WWII naval vessels.
