The Vengeance Fleet was created as a part of the Romulan Star Navy out of pragmatic necessity, but has since taken on a significant aspect of the continually ongoing conflict between the Klingon and Romulan Empires. The Romulans have never been known for wasting resources, and captured Klingon vessels have been used again their home nation for well over 200 years.
Unlike ships purchased from the Klingons in the later 2260’s through the 2280’s, ships of the Vengeance Fleet are more respected by fleet personnel. Ships such as the V-11 and N-8 are seen by most officers and men of the Star Navy as necessary evils in order to further the goals of the Empire. However, captured Klingon ships are thought of by many (including the Klingons) as a significant insult to the honor and warrior spirit of the Klingon Empire. This has made service aboard captured Klingon vessels far less distasteful than service aboard purchased ships.
To further connect the Romulan people to these ships, the Empire encourages an extremely unusual practice of allowing individual cities, colonies and even Senators and government officials to pay for and purchase the needed equipment and supplies to re-field vessels of the Vengeance Fleet. Senators are known to have invested significant parts of their personal fortunes to ensure these ships are refit for Romulan use, a facts they are happy to mention when re-election time comes around! Colonies are known for taking great pride in sacrificing their comforts to ensure that sufficient materials are available to send these captured ships successfully into battle. All of the known senatorial coalitions are known to have financed multiple ships and the Praetor is expected to fund no less than ten of the larger ships in the fleet.
Vessels in the Vengeance Fleet are not cataloged within the standard navy and are identified by their names. Nearly all vessels of the fleet are deployed against the Klingons, with multiple squadrons used for covert operations and subversive missions. A significant number of these ships are used in the Triangle as well to help besmirch the reputation of the Klingons in the region. Ship commanders are specially trained to use Klingon tactics when attacking Klingon allies along the boarder.
