The reference of this vessel's class possibly came from a piece of background artwork or a computer readout, although i must confess i've never seen such a thing about this particular vessel -- however, the Star Trek Encyclopedia is the source for this, and Okuda et al. mostly (but not always) made the Encyclopedia reflect references they had worked into a filmed production.

So I'm not sure how valid a case we have for specifying this ship's class, except that it was devised by the technical staff of the show -- there's no specific onscreen source, just the secondary Encyclopedia source -- and no model of this class was ever built. -- Captain Mike K. Bartel^talk

"[...] operating in the Bajor sector theater"? What does that mean? I thought it was a typo and the person meant to write "thereafter", but it's been changed back. Huh?

In describing military operations, a "theater" is an area where military operations are occurring. For example, someone could describe the Pacific in World War II as the "Pacific theater." --OuroborosCobra ^talk 02:00, June 10, 2010 (UTC)
