Cairo Station (Platform)

Cairo Station, Hull Classification Symbol ODA-142, is a Orbital Defense Platform in geosynchronous orbit above Earth, over the city of Cairo which gives it it's name. It is in the same battle cluster as Athens Station and Malta Station so it seems to be mainly guarding the area above the Mediterranean.

Station
The Cairo ODP main purpose is as a defensive station for Earth. It's main armament is a a Mk. V "Super" MAC gun, capable of causing severe damage to even a shielded Covenant warship with a single hit. It however does not seem to have any kind of point defense weapons, even though there is a possiblity of an A.I. aboard them as Cortana was on board the Cairo, because enemy boarding craft seem to get to the station unhindered. It runs on power transmitted from a planetside generator, much like the Type III prototype exosekelton.

Internal
Internally it is very similar to UNSC ships with set out decks and specialized rooms. It includes habitat areas, armories, a command center, firing control commons over looked by security rooms, recreation rooms, security centers, areas for storing MAC rounds, a monorail, terminals for the monorails, umbilical sections for docking vessels and hangers for various smaller craft. Its areas seemed to be either named after colors or named after parts of the NATO phonetic alphabet or after colors and then sometimes a number. These may refer to the deck they are on, how many there are on a deck or used for color coded guidance.

Like all UNSC space constructs it featured regular bulkheads for protection against hull breaches but seemed especially adept for fending of boarding actions. It had large stockpiles of Combat Barriers, large amounts of M247 GPMGs, security booths providing prefect defense points and regular weapons lockers in the walls holding BR55s and M7s.

The station includes large cargo elevators, stair wells for changing levels, numerous interconnecting corridors, airlocks, walkways outside the station and other facilities.

Armory A-01
Cairo Station Armory A-01 was the United Nations Space Command armory on the port side of Cairo Station. During the First Battle of Earth, Covenant boarders invaded Armory A-01. Stealth Elites armed with Plasma Rifles killed the Master Gunnery Sergeant, who was equipped with a shotgun.

Hangar A-01
Hangar A-01, also known as Hanger Bay A, is a generic United Nations Space Command term for one of the two-story Longsword and Pelican hangers on the port side of an Orbital Magnetic Accelerator Cannon Platform. During the First Battle of Earth, Covenant boarders invaded Hangar A-01. A Covenant Boarding Craft had docked and sent forth waves of Grunts and Elites. Marine defenders, equipped with Battle Rifles, SMGs, and even a Machine Gun Turret, were being overwhelmed at their position at the second floor when SPARTAN-117 came to assist, killing all the Covenant and repulsing them back to their landing ship. SPARTAN-117 then moved to adjacent Hangar A-02.

Hangar A-02
Hangar A-02, also known as Hanger Bay B, is a generic United Nations Space Command term for one of the two-story Longsword and Pelican hangars on the port side of an Orbital Magnetic Accelerator Cannon Platform. During the First Battle of Earth, Hangar A-02 was invaded by Covenant boarders. A Covenant Boarding Craft had docked and was sending forth waves of Grunts and Elites. Marine defenders were overwhelmed and forced to retreat to the mouth of the bay, where several soldiers equipped with Battle Rifles were under suppressive fire from two Plasma Cannons manned by Gunner Grunts on the second floor. Spartan 117 then arrived from Hangar A-01, bolstering the Marine forces. The group was able to kill all of the Covenant boarders and repulse them back to their landing ship.

Hangar C-01
Hangar C-01 is a generic United Nations Space Command term for one of the two-deck Longsword and Pelican hangers below the MAC gun on an Orbital Defense Platform. During the First Battle of Earth, SPARTAN-117 was able to take the Covenant bomb from Firing Control by wresting it from the hands of its Elite and Grunt guards, move it to Hangar C-01, and then activate the airlock door, explosively decompressing the bay. The SPARTAN-II was miraculously able to guide his trajectory to intersect with a nearby unshielded Covenant Assault Carrier. He then drifted away to UNSC In Amber Clad and detonated it, destroying the heavy warship.

MAC Storage
MAC Storage is a generic United Nations Space Command term for either of the two area on an Orbital Magnetic Accelerator Cannon Platform between the armories and Firing Control where MAC rounds are stored. Cairo Station MAC Storage refers to the area below Armory A-01 where MAC rounds are stored.

Umbilicals
Umbilicals are corridors branching out from UNSC geosynchronous SuperMAC platforms like Cairo Station to other ships that may dock to the station. During the First Battle of Earth, the Master Chief cleared the portside Umbilicals for Commander Miranda Keyes' safe passage to In Amber Clad before moving on to shipping to get to the Covenant Bomb.

History
In 2552, John-117 received the MJOLNIR Mk. VI armor in the Cairo armory prior to attending an awards ceremony on the station's command center. The ceremony was interrupted by the First Battle of Earth when thirteen covenant CCS-class Battlecruiser and two Assault Carriers assaulted Earth. They tried to break through the ODP by sending forth boarding craft to plant bombs on the station to take them out. Fleet Admiral Hood commanded the UNSC forces from the station during the attack. Unlike Athens and Malta, Cairo survived the Covenant attempt to detonate an Anti-Matter Bomb on board. In an ironic twist, the bomb was located and used by John-117 to destroy a Covenant assault carrier. When SPARTAN-117 returned later to Earth Cairo was still intact but appeared damaged from the battle. Lord Hood was still on board and in command of the escalating Second Battle of Earth. The Cairo, the other MAC platforms and three UNSC fleets held firm against the onslaught of the Covenant Loyalist forces.

It is most likely going to be featured in Halo 3.
