In an alternate 2366, these three  battle cruisers were part of a patrol that were ordered to intercept and attack the two Federation starships  and . The three battlecruisers attacked the Enterprise-D near the temporal rift while the Enterprise-C headed for the rift. During the battle, one of these Klingon ships was destroyed by the Enterprise-D while protecting the Enterprise-C. The two remaining K'Vort-class battle cruisers continued their attack on the now helpless Enterprise-D, almost destroying it. The timeline was restored once the Enterprise-C made its way through the temporal rift, thus ending the . ()

After Vagh informed Enterprise Captain Jean-Luc Picard that they had intercepted the transport, which suggested Federation support of the Kriosian rebels,  Vagh warned the Enterprise not to leave orbit, with this vessel decloaking moments later, and along with the two other vessels surrounded the Enterprise in a standoff. 

Klingon Ambassador , who was at the time aboard the Enterprise, warned Captain Picard that "Vagh is fully prepared to fire upon the Enterprise." ()

 Duras-loyal warships at Qo'noS  

In the final days of 2367, the first Bird-of-Prey, loyal to the House of Duras, engaged a surprise attack on Gowron's flagship, the , 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 . 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.

 Ferengi privateer salvaged Bird-of-Prey  

This Bird of Prey was one of two salvaged ships acquired by a group of renegade Ferengi lead by DaiMon Lurin.

In 2369 the DaiMon's Bird of Prey and its sister ship attacked a Starfleet science station, which had a complement of 103 personnel, on the planet of Ligos VII. Both ships later took part in the attack on the Federation starship . The Enterprise was able to inflict only minor damage on one of the attacking ships. The Ferengi boarded and captured the crew and beamed them onto Ligos VII to mine it. DaiMon Lurin and his men were eventually arrested when the Enterprises away team, who were turned into children, were able to recapture the ship. ()

Years later, following Odo's research in security breaches aboard the Enterprise, he noted to Worf of the incident, reminding him how on "Stardate 46235.7, Ferengi privateers led by DaiMon Lurin boarded and seized control of the Enterprise using two salvaged Klingon Birds-of-Prey." ()

 General Martok's task force  

These warships were among the task force consisting of "hundreds of ships" that General  brought to Deep Space 9 in early 2372. Upon arriving, crewmembers of these ships were granted shore leave aboard the station. 

As time passed, they began conducting random searches of vessels that traveled through Bajoran space. Following the incident between the  and the  over the unwarranted inspection of the , these ships moved out into unclaimed space, while numerous other remained stationed around Deep Space 9. 

When it eventually became clear to the Klingons that the Federation had no desire to support their proposed invasion of Cardassia, the task force cloaked and withdrew on a coarse directly for the Cardassian Empire. ()

 Attack on the Prakesh  
During the invasion, three Birds-of-Prey attacked the Cardassian  warship Prakesh, which was carrying members of the Detapa Council to Deep Space 9. 

As the Defiant entered the fray, it warned off the Klingon ships, but in response, was fired upon by the lead Bird-of-Prey. Initially, Captain Benjamin Sisko treated the Klingons with kid gloves trying only to disable their ships by firing at their engines, indeed, disabling the lead ship. Although removing one of their targets from the battlefield, their care ultimately proved ineffective. 

The second ship fired an aft photon torpedo at the Defiant, causing the Defiants tactical station to fritz out. As Worf took over the station, he explained that their attempts at disabling the Klingons were proving ineffective, forcing to allow use of deadly force. Several phaser shots later, the second ship was destroyed. 

Before the Defiant could full engage the third Bird-of-Prey, an attack cruiser joined the battle, and kept the Defiant from defeating the final Bird-of-Prey, which only took a few phaser hits, as it continued to attack the Prakesh. Following the rescue of the Prakeshs passengers and crew, the remaining Bird-of-Prey and the attack cruiser pursued the Defiant all the way back to Deep Space 9. 

En route, Gul Dukat, the rescued commander of the Prakesh, entered the Defiants bridge, thereupon immediately seeing Lieutenant Commander Worf and stating to Captain Benjamin Sisko, "are you aware that there's a Klingon on your bridge?" Unphased, Sisko explained that "He's not the Klingon you should be worried about," before asking Jadzia Dax to "Switch to aft view [and zoom to] maximum magnification," pointing out to Dukat the two pursing vessels. Dukat suggested that they cloak immediately, but Worf pointedly added that the Defiant had lost its cloaking device rescuing Dukat.

As the Defiant came into DS9's sensor range, Miles O'Brien noted to Kira Nerys that fact, adding that "they've got two Klingon ships on their tail." As the Defiant began hastened docking procedures, Dukat thought that it looked as if "the Klingons chased us all this way for nothing," believing that "Two ships against the station? I don't think they'd risk it." Dax then pointed added that she didn't think that it was "much of a risk" and she revealed to Dukat that those ships "have got friends", as they watch the two pursuing join the waiting Klingon fleet that surrounded that station. ()

 Klingon task force against Deep Space 9  
Markot's task force returned to Deep Space 9 and after a short bit of dialogue between the two sides, the Klingons opened fire on the station, beginning the first Battle of Deep Space 9.

After Worf and Kurn had acquired the necessary means of detonating the minefield, the  visited the site, warned all cloaked Klingon ships of their intentions, and detonated it. As the first grid of field erupted in explosions, two Birds-of-Prey were churned up, leading Miles O'Brien to commented that them driving out by detonating parts of their minefield was "just like ing quail." He reported to Major Kira Nerys that the ships were "setting course 327'215, back to the Klingon Empire." Thereafter, they intended to continue to detonating the minefield, and according to Kira, she wanted to "see how many other birds we can flush out of here." ()

 Convoy 6 Bird-of-Prey 

This Bird-of-Prey attacked Cardassian Convoy 6, which was being escorted by the . 

According to Miles O'Brien, during Worf's extradition trial, "There were two Klingon ships. A Bird-of-Prey and an old battle cruiser. One would engage us while the other went after the convoy, then they'd switch, the first ship going after the Cardassians while the second ship came after us [the Defiant]." ()

Like their Starfleet counterparts, the Klingon squadron fared little better, suffering substantial losses. ()

Gowron's fleet 

On stardate 50564.2 several 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. ()

 Second Fleet 

In late 2373, several 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  and , following the evacuation of DS9, for a counterattack against the Dominion forces. () 

Operation Return 

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. ()
