Construction Platform 966A
From Halopedia, the Halo wiki
Construction Platform 966A, alternatively nicknamed Station Delphi, was a deep space UNSC shipyard and construction platform. It was similar to refiting stations like the Cradle. Essentially, it is a massive plate of Titanium-A containing a floating city of welded scaffolding cranes, docking pods, tubes, and grappling claws.
The station was decommissioned in 2528 and abandoned near the Groombridge 34 System. Due to poor maintenence, the platform was a mess by 2531. That year, ONI arranged for the Spartan-IIs to be sent on a mission to the station to check for any "rebel activity." This was actually a guise for them to abduct Spartan-051 for use in the upcoming Spartan-III project.
