The following is a list of unnamed Klingon Birds-of-Prey.

By commanderEdit

By yearEdit

Three Klingon warshipsEdit

Federation-Romulan-Klingon stand-off

Backing up the Enterprise

In 2366, these Klingon warships, lead by the IKS Bortas, assisted the USS Enterprise-D in confronting two D'deridex-class Romulan warbirds. (TNG: "The Defector")

Rendezvous with the USS EnterpriseEdit

Officer Exchange rendezvous

In 2366, an unnamed Klingon Bird-of-Prey rendezvoused with the Enterprise-D so that Kurn, a participant in the Officer Exchange Program, could be beamed aboard the Federation flagship. (TNG: "Sins of the Father")

This may also be the IKS Hegh'ta, the vessel Kurn was next known to have served aboard.

Attack on the BortasEdit

In the final days of 2367, two unnamed Birds-of-Prey, loyal to the House of Duras, engaged a surprise attack on Gowron's flagship, the IKS Bortas, as it orbited Qo'noS, disabling its warp coils and aft shields with the first volley. It was soon joined by a second vessel, and both continued to inflict heavy damage to the Bortas. At a suggestion from Lieutenant Worf, the Bortas lured the attacking ships into attempting to board, believing the Bortas crippled, while Worf targeted the disruptors manually. This succeeded in destroying one of the ships, however the other managed to raise its shields in time, allowing it to cause further damage until it was at last driven off by the sudden appearance and attack from the IKS Hegh'ta. The attack signaled the beginning of the Klingon Civil War. Fortunately, the swearing of loyalty from Kurn and four other squadron commanders ensured that Gowron would not stand alone in the war.

Because of Worf and Kurn's actions in the battle, Gowron would restore family honor to the House of Mogh. (TNG: "Redemption")

Some of the footage of these ships was taken from Star Trek III: The Search for Spock and "Yesterday's Enterprise", while other portions were new visual effects.

Attack on the PrakeshEdit

Vorcha and Kvort class

The pursuing ships

These starships, composed of several Birds-of-Prey and a Vor'cha-class cruiser, attacked the Cardassian Galor-class starship, the Prakesh, in early 2372.

One of the Birds-of-Prey were destroyed and another disabled by the USS Defiant, but the third destroyed the Prakesh with the help of the Vor'cha cruiser.

The two surviving ships later pursued the Defiant to Deep Space 9, where they participated in the attack on the station. (DS9: "The Way of the Warrior")

Encounter near Ty'GokorEdit

A Bird-of-Prey on the viewscreen

In early 2373, this Bird-of-Prey was encountered by Gul Dukat in his commandeered Bird-of-Prey while transporting Captain Benjamin Sisko and his crew on a covert mission to Ty'Gokor. When the holofilter Dukat normally used to impersonate a Klingon captain failed, Worf offered to speak with them. Dukat, however, chose to fire on the other Bird-of-Prey, destroying it. (DS9: "Apocalypse Rising")

Ty'Gokor fleetEdit


Ty'Gokor ships

These starships, again Birds-of-Prey and Vor'cha-class cruisers, were among those that protected Klingon High Command at Ty'Gokor. (DS9: "Apocalypse Rising")

Gowron's fleetEdit

On stardate 50564.2 several unnamed Klingon Birds-of-Prey were among the large contingent of Klingon warships that arrived at Deep Space 9 after falling back from Cardassian space, following the Cardassians declaration of joining the Dominion. Several more later arrived at DS9, and were among the last of Gowron's fleet to reach the station. (DS9: "By Inferno's Light")

Second Fleet Edit

Second Fleet

Several Klingon Birds-of-Prey in the Second Fleet

In late 2373, several unnamed Klingon Birds-of-Prey belonged to the Second Fleet.

While the Dominion attacked Deep Space 9, during the second Battle of Deep Space 9, several of these vessels crossed the Cardassian border and destroyed the Dominion shipyards on Torros III. These ships later joined with the USS Defiant and IKS Rotarran, following the evacuation of DS9, for a counterattack against the Dominion forces. (DS9: "Call to Arms")

Operation ReturnEdit

Klingon fleet, Sacrifice of Angels

The Operation Return ships

This fleet, comprised of Birds-of-Prey and Vor'cha-class cruisers, was led by Martok and Worf, after they persuaded Chancellor Gowron to contribute them to Operation Return. One of these Birds-of-Prey was destroyed by friendly fire.

The ships turned the tide on the battle and managed to outflank the Dominion, opening a hole through their lines for the Federation fleet. (DS9: "Sacrifice of Angels")


Klingon-Borg encounterEdit

Unnamed Birds-of-Prey in battle with a Borg cube

While undergoing a neural link with the Borg Cooperative, USS Voyager's first officer Chakotay became aware of at least one, otherwise unspecified, pitched battle the Empire fought against a Borg cube of the same type that engaged Starfleet in the Battle of Wolf 359 in 2367, and in which at least two unnamed Birds-of-Prey were involved. Like their Starfleet counterparts, the Klingon squadron fared little better, suffering substantial losses. (VOY: "Unity")

The battle scene shown in Unity was stock footage from DS9: "Emissary", "The Way of the Warrior", newly edited in post-production.

Mirror universeEdit

Alliance cruisersEdit

Klingon bird-of-prey, Shattered Mirror

Two Birds-of-Prey attacking Terok Nor

Two of these unnamed Birds-of-Prey were dispatched to Terok Nor, along with the Regent's flagship, to put down the Terran Rebellion in 2372. (DS9: "Shattered Mirror")
