 vessel; although this idea was later dropped, the Bird of Prey maintained its cloaking device as a plot point in the film and the Romulan bird feather patterns on its wings were kept. The Bird of Prey is the first Klingon vessel depicted with a cloaking device; all classes chronologically later in the series would also use a cloaking device. The wings of the Bird of Prey are able to move, lowering to attack, maintaining just above horizontal in flight mode and raising high when the ship lands. However, as the studio model's mechanism for moving the wings broke, in later Star Trek series' episodes the wings are usually fixed in either flight mode or attack mode. This was not rectified until the creation of a CGI model for the vessel. The studio models for the Bird of Prey were sold in the 2006 Christie's auction; the original model sold for US$307,200, while an enlarged wing, used for close-up shots in Star Trek V: The Final Frontier

Although several variants are seen throughout the franchise, design notes state that the Bird of Prey has two main classes: the B'rel-class and the K'Vort-class.

Likewise, both classes are equipped with cloaking devices and are capable of impulse and warp speeds.

Heavy cruiser
The heavy cruiser was a type of cruiser, a naval warship designed for long range, high speed and an armament of naval guns roughly 203mm calibre . The heavy cruiser can be seen as a lineage of ship design from 1915 until 1945, although the term 'heavy cruiser' only came into formal use in 1930...

The design of the Vor'cha-class maintains the typical Klingon configuration with a forward module supported by a thick horizontal neck running aft and spreads out into a larger secondary hull. With a crew of 1,900 and a length of 500 meters, Vor'cha-class vessels are one of the largest Klingon ships in the Star Trek universe. They are heavily armed, sporting 18 disruptor cannons as well as three photon torpedo launchers. In addition, the forward section of the cruiser is equipped with a particularly powerful disruptor beam. The ships are equipped with both warp and impulse engines, and make use of cloaking devices. In the Deep Space Nine episode "Return to Grace", the cruiser is stated to have enough firepower to threaten subterranean bases with orbital bombardments. The Vor'cha-class is frequently seen in The Next Generation and Deep Space Nine episodes depicting Klingon ships; in its earliest appearances, the class represents the flagship

. Later appearances use the ship as the mainstray vessel in Klingon fleet engagements.

Negh'Var-class

The Negh'Var-class warship is the largest and most heavily armed Klingon vessel seen in the Star Trek franchise. The class initially was designed by Rick Sternbach to appear as a Klingon attack cruiser for an alternate timeline in "All Good Things...", the series finale of The Next Generation. Sternbach built the studio model for the vessel on top of the existing studio model for the Vor'cha-class attack cruiser. A slightly modified studio model was used in the Deep Space Nine episode "The Way of the Warrior", in which the Negh'Var-class is properly introduced to the audience. A CGI version of the model was eventually produced for the Voyager series finale "Endgame", incorporating elements from the models used in both "All Good Things..." and "The Way of the Warrior". The Negh'Var-class is also used in the episodes "Shattered Mirror" and "The Emperor's New Cloak" as a flagship in the Mirror Universe

Martok is a recurring character in Star Trek: Deep Space Nine, played by actor J. G. Hertzler.-Overview:Little backstory is given regarding the early life of Martok, except for a brief history sketched by himself in the Deep Space Nine episode "Once More Unto the Breach"...

. As the studio model is built upon that of the Vor'cha-class, the Negh'Var-class shares many similarities in design in relation to the vessel's shape, color and nacelles. However, with a length of nearly 700 meters and a crew of 2,500, the Negh'Var-class is substantially bigger than the Vor'cha-class. The ship is equipped with a cloaking device. The class is heavily armed, with 20 disruptor banks and four torpedo launchers, as well as a large forward disruptor cannon protruding from the forward section. The Negh'Var-class only appears in a few episodes; other than in the climatic battle of "The Way of the Warrior", it is not used in any fleet battle scenes.

 of Enterprise, Eaves' team was unable to work through the night to make the alterations. Therefore, the producers decided to use an older CGI model in its place; the only other model available was a K't'inga-class battlecruiser made for Deep Space Nine. The use of the K't'inga-class created a continuity error in the series, with the same ship design seemingly in use for 225 years. For this reason, the producers decided that the K't'inga-class model would not be used again as it did not fit with Enterprises theme. The designers involved later voiced their regret at having to use the older model, but acknowledged that there was no alternative due to the team's exhaustion.

; Doug Drexler later refined Eaves sketches to create a CGI mesh using LightWave 3D. Foundation Imaging converted Drexler's work into the final CGI model seen in the episode. Eaves' objective was to make the craft appear more primitive than the Klingon ships later in the franchise's chronology, with exposed piping and rugged design. Eaves stated that the design was made to look "like it is made up of different pieces that are attached to one another, as opposed to a uniform shape". Several designs of various sizes were proposed before Zimmerman settled on the Raptor-class. While the vessel is lightly based on Industrial Light & Magic's Bird of Prey, Eaves attempted to make the craft appear as a precursor to the D7-class. Drexler, who worked closely with Eaves during the creation of the CGI mesh, was allowed to deal with the closer details of the model, such as the position of the shuttlebay

An ironclad was a steam-propelled warship in the early part of the second half of the 19th century, protected by iron or steel armor plates.

The ship is armed with two torpedo launchers and a disruptor array mounted towards the back of the ship. Like most Klingon ships, it has both impulse and warp drive. The Raptor-class only appears in one episode in the series, although its schematics are visible on several computer screens in later episodes.
