Hephaestus class

The Hephaestus-class was a type of Federation advanced escort starship in Starfleet service in the early 25th century, a subclass of the design. These vessels were usually commanded by an officer holding the rank of one-star rear admiral or higher. An enhanced version, the fleet advanced escort, was available for vice admirals. 

Specifications
The Hephaestus-class was an escort, i.e. a Starfleet warship. Phaser cannons were standard equipment on these ships. The saucer, nacelles, pylons and hull were interchangeable with -, Phoenix- and starships. Compared to its mother class, the Hephaestus looked lean and mean. 

Livery
In the 25th century, the design of the Hephaestus-class advanced escort allowed its commanding officer to choose from different designs of livery, which could be modified further at starbases. These options were designated Type 1-5 and Veteran. 

Furthermore, the installation of deflector shields from specific factions modified the hull appearance, including shields from the Reman Resistance, the Breen Confederacy and the Dominion.
