P.S. Then there's the mystery of Torp Bay 4 (eek).
Completely ignoring that! I have to update my old torpedo bay sometime soon, as when I built it I'd imagined two torpedo bays next to each other and labeled the port side bay as "2" with a starboard door leading to "1" (obviously, now that I'm much more familiar with the actual size of the exterior of the ship, two full-sized torpedo bays right next to each other won't fit realistically).
Perhaps when I do update my old torpedo bay, I'll just have a sign that says "TORP BAY" and instead of a number below it, I'll have the department logo for Weapons & Defense?
