Covenant vessels like the Ardent Prayer are a prelude to the devastation the full fleet can visit upon a planet.
The ship was one of the main targets of Operation: UPPERCUT, and was boarded by multiple Sabre craft in an effort to plant a Shaw-Fujikawa Translight Engine on board, which would be used to destroy a nearby Covenant Supercarrier. During the mission, the ship's communications were knocked out and the bridge crew eliminated in order for the ship to be permanently locked onto its refueling track with the supercarrier. The operation succeeded, and Ardent Prayer, along with the supercarrier Long Night of Solace, was destroyed by the rigged Slipspace drive.
- The Ardent Prayer is the setting of the Halo: Reach multiplayer map Zealot, and the Firefight map Corvette.
- All Covenant Starships are commanded by a ship master or fleet master rank Sangheili Zealot, the fact there is no zealot aboard may imply further that the golden armoured Sangheili ship masters, are in fact of the General rank, as is shown in this Corvette.
- The Shipmaster of the Ardent Prayer is named Ardo 'Moretumee as revealed in Halo: The Essential Visual Guide.
