A class of Annari warship was utilized by the Annari in the late 2370s.
In 2377, vessels of this type intercepted the Kraylor vessel "Nightingale", after the ship's cloaking device malfunctioned. The device was repaired in time before the Annari could destroy the ship.
The Annari also used this ship type to blockade the Kraylor homeworld. They used a series of "pulses" to illuminate cloaked vessels. (VOY: "Nightingale")
