In some cases, the Maquis modified these courier vessels to specifications comparable to an interceptor, including improved engine capability and light armaments. These vessels were commonly used during their insurrection against the Cardassian Union. In 2371, Kira Nerys and Odo pursued a modified Peregrine-class courier into the Badlands after it attacked a Lissepian supply ship near Prophet's Landing. (DS9: "Heart of Stone")
Backgound information Edit
The designation "Peregrine-class" was only mentioned in "Heart of Stone", where the design was not seen.
Star Trek Online identifies this as the class designation of the Federation attack fighter. The fact that the ship was referred to as a former courier ship modified by the Maquis, would support the association.
