Ivanoff Station

Ivanoff Station - designation ONIRF IS-004920//001-54 - is a UNSC orbital research facility stationed in an asteroid field near Installation 03. It was built after the Office of Naval Intelligence discovered the location of the Installation shortly before the end of the Human-Covenant War.

History
In March 2553, Dr. Catherine Halsey was indefinitely detained here by Admiral Margaret Parangosky, as retribution for lying to her about the creation and deployment of flash clones during the SPARTAN-II Program's early phases. Catherine Halsey was later allowed to work on the, although she was transferred back to the station after finishing. However, she was relocated off the station at some point and was later taken back aboard the Infinity in early 2558.

The Office of Naval Intelligence transported several objects removed from Installation 03 to Ivanoff Station, including the ring's Activation Index and the Composer, a machine capable of converting living beings into digital form. As a result of an accident with the Composer, in which several scientists studying the artifact were digitized, the UNSC discovered the coordinates to Requiem.

Searching for the Composer after being revived on Requiem, the Didact traveled to the station and attacked it with Covenant forces loyal to him. Despite the efforts of the Master Chief who had hitched a ride on a Lich, the Didact succeeded in getting the Composer and fired it at Ivanoff Station, digitizing everyone except the Master Chief who had an immunity to the weapon activated in him earlier by the Librarian. With everyone in the station dead and the Didact leaving, the Master Chief abandoned the station in one of its F-41 Broadsword fighters armed with one of the station's excavation-grade HAVOK tactical nuclear weapons in hopes of stopping the Didact from doing the same to Earth. With the help of the, the Master Chief succeeded in destroying Mantle's Approach and the Composer, but not before the city of New Phoenix was composed like the station. In the aftermath of the Raid on Ivanoff Station, a handful of the Ivanoff's personnel managed to escape into the nearby asteroid field and were later saved by search and rescue teams.
