The Hub is the command facility of Frontier-class space stations such as the new Deep Space 9. The crew of the new Deep Space 9 had previously called their command facility the operations center, just as the first Deep Space 9 had, but later changed it to the Hub due to its disc shape and its location at the top of the space station. Jefferson Blackmer referred to the Hub as being like an inverted starship bridge. The Hub had a sunken area called the Well, where the Hub situation table was located.
