Description
In the final months of the Human-Covenant War, Installation 00 constructed a replacement for Installation 04, which had been destroyed by John-117 during the Battle of Installation 04. The still-incomplete replacement ring, Installation 04B, was launched from the Ark's Foundry during the war's final battle, but was subsequently destroyed by its own premature firing, initiated by the Master Chief and Cortana in order to sterilize a Flood incursion on the Ark. The ring's firing severely damaged the Ark, though the massive installation was able to repair itself in time, and by March 2559, the Ark's Foundry had finished constructing a new replacement ring.

During the battle between the UNSC forces of the UNSC Spirit of Fire and the Banished occupying the Ark, the newly-built replacement Halo was discovered by Professor Ellen Anders. Consequently, she and Captain James Cutter formulated a plan to deploy the ring to the Soell system, Installation 04's former site, where it could be used to raise a distress beacon to the UNSC.

While the Banished contested the UNSC for control of the new Halo, the forces of the Spirit of Fire managed to gain a foothold, allowing Anders to enter the control room where she successfully disarmed the ring's firing mechanism and manipulated its gravity anchors to eject a section of the Halo's landmass housing Banished forces into space. While the UNSC forces evacuated back to the Spirit of Fire, Anders could not make it out of the control room in time before Installation 04C entered a slipspace portal to the Soell system. En route to its destination, however, the Halo was intercepted by a Guardian.
