History[edit]

Day of Jubilation, along with Solemn Penance, was attached to the High Prophet of Regret's Fleet of Sacred Consecration. Together, both assault carriers glassed dozens of human colonies throughout the Human-Covenant War.^[3] After the Battle of Meridian, Day of Jubilation accompanied the Prophet of Regret and the rest of the Fleet of Sacred Consecration to what they believed to be the Forerunner world of Erde-Tyrene, which unbeknownst to them was actually humanity's homeworld—Earth.^[4] Exiting slipstream space over Jupiter in the Sol system,^[5] the fleet moved towards Earth and arrived at the planet on October 20, 2552. Day of Jubilation and the fleet soon engaged in combat with the UNSC Home Fleet, escorting Regret's flagship Solemn Penance into Earth orbit. During the opening actions of the battle, both carriers deployed hundreds of R'sisho-pattern Ticks to neutralize the network of orbital defense platforms that stood in the way of the Prophet's advance. Even as it came under fire from the numerically superior human forces, Day of Jubilation sped through the UNSC's lines and past Cairo Station, following the destruction of both Athens and Malta stations in its battle cluster. Numerous warships from the UNSC Navy's Fifth Fleet gave chase and moved in to attack.^[1]

After disarming the Chershi-pattern antimatter charge meant to destroy Cairo Station, Master Chief Petty Officer John-117 disembarked into open space to deploy the bomb against the Covenant armada; Day of Jubilation was selected as his target as the Home Fleet had succeeded in bringing down the carrier's shields and remained in orbit as Regret's flagship raced towards the surface of Earth. With cover from the Fifth Fleet, the Master Chief floated in free-fall towards Jubilation, which disabled Marathon-class heavy cruiser UNSC Feeling Lucky with its ventral energy projector. As the Spartan closed in, a wing of Longswords conducted a bombing run on the carrier's core, allowing John direct access to the carrier's massive pinch fusion reactor. Day of Jubilation was completely destroyed when John detonated the bomb and fled back into space, though Solemn Penance successfully escaped past Earth's ODP networks.^[1]

Parts of the complement managed to escape from the Jubilation, using dropships, drop pods, and even boarding craft. The survivors were scattered across Earth, and many planned to regroup. Although they were seemingly stranded when the Prophet of Regret escaped during the Battle of Mombasa, a large support and excavation fleet of Jiralhanae-led Covenant reinforcements arrived at Earth shortly afterwards. Unbeknownst to the Jubilation crew, the Jiralhanae were given orders to execute the Sangheili. Those who revealed themselves to the Jiralhanae were killed, prompting many to seek refuge elsewhere. Some Covenant, including one Sangheili later known as Peter, surrendered to the UNSC and were interrogated. These members of the Covenant would form a large group of alien asylum seekers on Earth after the Human-Covenant War.^[6]

Production notes[edit]

Early in Halo 2's development, the assault carrier was going to host the level Covenant Ship, during which John-117 would board the carrier alongside Miranda Keyes and a team of ODSTs.
In Halo: Rendezvous With Ramen, during Peter's account, the Day of Jubilation was mistakenly called the Day of Retribution before being referred to as simply Jubilation.
