After the success of the Defiant class in the Dominion War, it was clear that small, heavily-armed starships had a role to play in Starfleet.
Production on these warships diminished in the 2380s in favor of exploration and multi-purpose vessels, and several prototypes were abandoned in the planning stages. In the early 2390s, however, tensions with the Klingon Empire and the Romulans were on the rise and Starfleet Command looked once again for ships capable of holding their own in battle that didn't require the commitment of crew and resources of a larger vessel. The first of the new class of ships was the Vigilant.
With a design inspired by the Defiant class, the Vigilant is designed for one thing: combat. It has limited space for crew and no quarters designed for families or guests, a feature that is standard on Starfleet vessels assigned to long explorations. Also missing are many of the comforts common to Federation vessels, including recreational facilities and lounge areas. A multi-purpose space provides room for both relaxation and physical training.
