In 2374, the Traynor joined the IKS Rotarran, the USS Centaur, the USS Lyric and the IKS K'lashm'a in a diversionary attack on a Dominion Ketracel-white storage barge near the Argolis Cluster. Benjamin Sisko, commanding the fleet from the Centaur, ordered the Traynor to attack the barge and also had Martok alternate the lead position between the Traynor, the Rotarran and the Lyric to make the Jem'Hadar confused as to which ship was leading the attack.
The Traynor was destroyed in action several weeks later. It had been planned that the Traynor would be part of the attack to retake Deep Space 9 and Captain Sisko mourned its loss. (DS9 - The Dominion War novelization: ...Sacrifice of Angels)
