Arcturus Station (Earth-5875)

Arcturus Station was a major UNSC Stanford torus-type space station located in the Arcturus system. It was commanded by Fleet Admiral Steven Hackett.

History
Arcturus Station began construction around Themis in 2251 and finished in 2252, in the Arcturus system. For the construction, multiple metal-rich asteroids in Thebis were utilized. Despite the finished product, the station was only inaugurated in 2256, becoming the principal political and military headquarter of the UNSC Navy outside of Earth and Reach ever since the Interplanetary War.

In 2519, during the Secession, Jack Harper traveled to Arcturus in order to exchange UNSC prisoners with Captain George Williams. Harper's partner Eva Coré was successfully traded for a group of UNSC Marines, the latter which were examined at the station's medical bay, while the two Insurrectionists escaped.

Jeffrey Moreau was born on Arcturus Station in February 8th, 2532, who went to become an important member of the N7.

Following the First Contact War, in 2556, Arcturus Station became the site of the first flight test of the top-secret stealth ONI prowler UNSC Normandy, designed in collaboration with the Swords of Sanghelios. Fleet Admiral Ernst Hood, Captain Petros Dillard and Fleetmaster Rtas 'Vadum all attended the test flight, overseeing the Normandy's capabilities.

Design
Arcturus Station was a 5-kilometer diameter, Stanford torus-type space station, being at the trailing Lagrange point (L5) of the gas giant Themis. The station had a permanent population of 45,000, many of which grew to enlist in the UNSC Navy.

As the former headquarters of the UNSC Navy, Arcturus Station was the command center of the Fifth Fleet, the second biggest fleet of the UNSC after the Home Fleet, commanded by Fleet Admiral Steven Hackett, guarding the route to the Sol system. Its centralized spot made the station the ideal point for both defense and slipspace-jumping off point for exploration. It was also a shipyard, with the Kilimanjaro-class dreadnought UNSC Aconcagua being built around the station.
