From Halopedia, the Halo wiki
Almighty Persuasion was a warship in service of the Covenant and under the command of Fleetmaster Nizat 'Kvarosee of the Fleet of Inexorable Obedience, tasked with carrying one of the Luminal Beacons. The ship, and its beacon, were destroyed in early 2526 during the Attack on Zhoist by the UNSC as part of Operation: SILENT STORM. During the attack, the humans deployed a series of Octanitrocubane explosives throughout the Ring of Mighty Abundance, a fleet support ring constructed around the planet. The resulting destruction saw the destruction of a huge number of ships including the under-construction Hammer of Faith and the Almighty Persuasion.
The destruction of the Persuasion and its Luminal Beacon cargo was a huge blow to the Covenant, partially resulting in the Fleetmaster being removed from his command role.
