The Hornet was part of the Captain Picard's hurriedly thrown-together task force that blockaded the Klingon-Romulan border during the Klingon Civil War in 2368. The ships of this task force formed a tachyon detection grid in order to detect cloaked ships trying to make it over the border. (TNG episode: "Redemption, Part II") The Hornet was commanded by Captain Peterson. (TNG novelization: Relics) During the latter stages of the Dominion War, the Hornet put in for repairs at Deep Space 9 in 2375. (DS9 episode: "Inter Arma Enim Silent Leges")
