The Clarion was a warship of the Bajoran Militia's Space Guard.

In 2323, the Clarion was under the command of Colonel Li Tarka when Cemba Station was bombed. The Clarion was able to beam off many survivors including City Watch officer Darrah Mace. Soon after, the Clarion was sent, alongside the Glyhrond, to take revenge against the Tzenkethi who were believed to have carried out the attack. The crew was successful and engaged a Tzenkethi marauder, which it was on the verge of destroying when Cardassian warships appeared and beamed bio-weapons onto the Clarion, wiping out its crew. Following that the Cardassians destroyed the Clarion with the Tzenkethi warship. (TLE - Terok Nor novel: Day of the Vipers)
