Anvil Station is a secret UNSC space station in orbit over an unknown planet. The Spartan-IVs and Swords of Sanghelios Sangheili warriors use the station to run War Games exercises in which they hone their combat skills and test experimental technology.
Crew and complement
ANVIL Station is defended by dedicated squadrons of interceptors, with their pilots sporting the AVIATOR Mjolnir. The station has an additional internal security detail, with Spartans attached to these units noted to prefer the AIR ASSAULT armor.
ANVIL Station is the result of a classified partnership between the UNSC and Swords of Sanghelios, retrofit to support the newly-established Anvil Initiative and Project CRUCIBLE. ANVIL Station was designed for the UNSC to test skunkworks technologies clandestine prototypes, some destined for full and successful production runs, other merely serving as a stop-gap in the development pipeline of Mjolnir components, weapon advancements, and more. Additionally, the station proved home to combat test simulations for both Spartan and Sangheili troops, hoping to test technologies and hone their combat skills.
The station has seen the oversight and testing of the following MJOLNIR suits;
Built by the UNSC, Anvil Station was created for the Spartan-IV program for use in training human and Sangheili forces. The station consists of a large, cylindrical mid-structure featuring a command center on top. The structure is surrounded by two disk-shaped facilities, with the upper one consisting of several decks used for simulation training, and the lower one comprising of living quarters. At the lower end of the station are docking ports for transport modules. The station has a projected operational life of 250 years and in total there are 7365 humans and Sangheili working on-board.
On January 28, 2552, the designs for the station were approved. As early as 2553, the ANVIL initiative saw a number of very select joint training engagements between Spartan-IVs and Swords of Sanghelios Sangheili.
On January 28 2555, the station saw heavy use of experimental technology in use between Sangheili and Spartans.
During development, ANVIL Station was referred to as "Crucible Station".
The Anvil Station was the setting for the cancelled Halo Online game. After the game's cancellation, both the station and the Anvil Initiative have been mentioned in ancillary media, such as Halo: Official Spartan Field Manual. With the arrival of Season 5: Anvil on Halo: The Master Chief Collection, the ANVIL Station was mentioned for the first time as the testing ground of several new armors added into Halo 3's armor customization and the namesake of the aforementioned Season.
