The Incorruptible was an ORS-class heavy cruiser serving within the Covenant Navy. It was attached and affixed to the Second Fleet of Homogeneous Clarity  and was crewed by Sangheili from the elite Dn'end Legion.
During the 9th Age of Reclamation, the vessel was commanded by Tano 'Inanraree. It was a vanguard ship of High Charity and the Defense Fleet, following the holy city likely from Installation 04 to Installation 05, and safeguarding it during the Battle of Installation 05.
Battle of High CharityEdit
During the Battle of High Charity, 'Inanraree had ordered the ship to be infected by the Flood, as he was a member of the Governors of Contrition, a radical fringe sect of the Covenant who believe that all creations of the Forerunner are sacrosanct (sacred), even the Flood. However, a crewmember, Major Voro 'Mantakree, with the support of the rest of the crew, killed the Shipmaster using a Needler-pistol weapon, and thus gained control of the vessel.
'Mantakree then fended off attacks from Chieftain, Gargantum, who controlled several ships. They then fled to the outpost world Joyous Exaltation in the Salia system, heeding the call of Imperial Admiral Xytan 'Jar Wattinree.
The Imperial Admiral gave Voro the rank of Zealot and made him a Fleet Master. The Incorruptible was assigned as the flagship of a small fleet of 30 ships sent to Onyx to chase the captured destroyer Bloodied Spirit and prevent the Humans from taking Forerunner artifacts.
Battle of OnyxEdit
- Main article: Battle of Onyx
The Incorruptible, along with its ships, took part in the Battle of Onyx where it was destroyed by HORNET Mines laid by the prowler, UNSC Dusk. Anything that remained of the ship or the fleet was destroyed when Lieutenant Commander Kurt Ambrose detonated the FENRIS Nuclear Warheads and when the hundreds of thousands of Sentinels destroyed the planet from the inside.
- Voro Nar 'Mantakree - Shipmaster
- Uruo 'Losonaee - Operations officer
- Zasses 'Jeqkogoee - Navigation officer
- Y'gar 'Pewtrunoee - Communications officer
- Paruto Xida Konna - Security
- Waruna Xida Yotno - Security
- Tano 'Inanraree - Shipmaster
- The name of the ship is rather ironic, as the Shipmaster tried to corrupt the ship by letting the Flood on.
- The name Incorruptible was shared by a British aircraft carrier in the Second World War.
