Installation 06

Installation 06, also known as Gamma Halo, is one of the seven rings that comprise the Halo Array. It was originally part of a smaller array of six Halo installations with a diameter of 10,000 kilometers, as opposed to the 12 larger, 30,000-kilometer-wide Halo rings. After the threat of the Halo Array was stopped at the Ark, the UNSC established research facilities on Gamma Halo.
