By encounter Edit
Governor Vagh's attack cruiser Edit
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.
Alliance cruiser 1 Edit
That year, while on standard patrol, it's crew observed the prime universe Starfleet runabout USS Rio Grande seemingly "appear out of nowhere." Two crewmembers from this vessel boarded the runabout, but were startled to see Kira Nerys, and promptly excused themselves, offering to escort them back to Terok Nor.
Later, when Nerys and Julian Bashir escaped Terok Nor, this cruiser pursued the runabout as it attempted to return to the location of the Bajoran wormhole. Disruptor fire from the cruiser knocked the runabouts shields down to sixty, then forty percent, before they were knocked out completely, moments before the runabout returned to its original universe. (DS9: "Crossover")
Alliance cruiser 2 Edit
That year, as based on information from Terran Rebellion member Rom, this ship along with two Galor-class cruisers were able to apprehend the Terran fighter that piloted by Smiley O'Brien and Benjamin Sisko (of the prime universe) as they attempted to infiltrate Terok Nor. (DS9: "Through the Looking Glass")
General Martok's task force Edit
These warships were among the task force consisting of "hundreds of ships" that General Martok 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 IKS M'Char and the USS Defiant over the unwarranted inspection of the SS Xhosa, 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 Edit
In early 2372, this attack cruiser joined three Birds-of-Prey in their attack on the Cardassian Galor-class starship Prakesh (carrying members of the Detapa Council to Deep Space 9), following the entry of the USS Defiant into the fray.
The Defiant used its tractor beam to significantly reduce the effectiveness of the cruiser's disruptor weapons while it beamed the Prakesh passengers and crew aboard. The ship and the remaining active Bird-of-Prey then pursued the Defiant all the way to DS9.
En route, Gul Dukat, the rescued commander of the Prakesh, entered the Defiant's 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 sensor range of DS9, 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 Edit
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.
During the battle at lest two attack cruisers were destroyed with many others heavily damaged. It wasn't until the arrival of Federation reinforcements, along with the fact that DS9 proved capable of holding its own in battle, that the Klingons task force finally withdrew back into Cardassian space. (DS9: "The Way of the Warrior")
Ty'Gokor warships Edit
Borg engagement Edit
While undergoing a neural link with the Borg Cooperative in 2373, 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 this attack cruiser was involved. Like their Starfleet counterparts, the Klingon squadron fared little better, suffering substantial losses. (VOY: "Unity")
Chancellor Gowron's fleet Edit
On stardate 50564.2 several attack cruisers 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, and the arrival of the Dominion fleet. 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
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 Return Edit
These warships were led by Martok and Worf in Operation Return, after they persuaded Chancellor Gowron to contribute them. The ships turned the tide on the battle and managed to outflank the Dominion. (DS9: "Sacrifice of Angels")
Deep Space 9 stationed cruiser 1 Edit
This attack cruiser, along with three Klingon Birds-of-Prey, and two Miranda-class starships, were stationed on patrol near Deep Space 9 shortly after the starbase was retaken by the Federation in 2374. (DS9: "You Are Cordially Invited") The same grouping of ships was again present at DS9 in 2375. (DS9: "Strange Bedfellows")
Sirella's transport Edit
This attack cruiser transported Sirella, the Mistress of the House of Martok, to Deep Space 9 in 2374, to evaluate Jadzia Dax for her worthiness to join their Great House. (DS9: "You Are Cordially Invited")
First Battle of Chin'toka Edit
Deep Space 9 stationed cruiser 1 Edit

Deep Space 9 stationed cruisers 2 Edit
Battle of Cardassia Edit
Mulitple attack cruisers fought at the Battle of Cardassia and later joined Federation, Klingon, Romulan, and Cardassian forces on their journey to liberate Cardassia Prime from the Dominion. Several were destroyed in suicide runs made by Jem'Hadar fighters. (DS9: "What You Leave Behind")
Battle of Procyon V Edit
In an alternate timeline, occurring during the 26th century, this attack cruiser participated as part of the Federation fleet involved in the pivotal Battle of Procyon V against the Sphere-Builders. (ENT: "Azati Prime")
