Vigilant class

## SPACECRAFT CLASS

The ***Vigilant*-class** was a type of spacecraft developed by Starfleet in the late 24th century. It was an experimental subclass of the *Defiant*-class and only a single vessel entered active service.

## History

Though only a single starship was constructed to *Vigilant* specifications, components of the design tested well and were used to refit *Defiant*-class vessels.

## Technical specifications

The *Vigilant*-class was just as powerful and nimble as the standard *Defiant*-class, although it was larger in size and featured an updated nacelle design.

### Tactical systems

The design carried the 4 Type-XII pulse phaser cannons made famous by its parent class. To add to this offensive firepower, engineers added 2 Type-VIII phaser lances, 2 Type-X phaser arrays, and 2 Mk 90 variable-payload launch tubes.
