A common, small Romulan assault ship, the Temar Vestari is used in situations that warrant greater manueverability and firepower than is offered by the larger Retalla Vastamri. The ships's armament of two blast beams, while weak, makes it suitable for providing for its own defense. In many cases Temar Vestari Assault Ships are used as commando units, charging ahead with the main battleline with the hopes that some or all of the assault ships will make it through the planetary defenses in order to reach transporter ranges.

The class is named from the Romulan temar vastari (night flyers), in reference to a large reptilian bird of Hannrileth, solid black in color. In keeping with its namesake, the assault ships reportedly are painted midnight black.
