An '''orbital defense platform'''<ref>'''Halo: The Fall of Reach''', ''page 330''</ref> ('''ODP'''),<ref>'''Halo Encyclopedia''', ''page 294'' (2011)</ref> also known as an '''orbital weapon platform''',<ref name="cairo">'''[[Halo 2]]''', campaign level ''[[Cairo Station (level)|Cairo Station]]''</ref> is a class of large [[UNSC]] space stations used to defend locations of great importance, typically planets of a high strategic value. They have the [[hull classification symbol]] of '''OWP'''. | |||
Orbital defense platforms are frequently placed in [[geosynchronous orbit]] and deployed in groups, or clusters, of two to five platforms. The well-equipped and large bridge of an ODP is suitable for directing large-scale engagements. Such was the case when [[Lord Hood|Fleet Admiral Sir Terrence Hood]] directed UNSC forces from an ODP during the [[Battle of Earth]]. These platforms are capable of destroying even the largest of [[Covenant]] capital ships but are vulnerable to [[Covenant boarding craft]] which can avoid the heavy slugs and latch onto the stations. Thus, it is up to the UNSC personnel within the stations to repel any [[Boarding|boarders]].<ref name="cairo"/> | |||
== | ==Facilities== | ||
Internally, the stations are remarkably spacious, complete with high ceilings and a monorail system to move personnel and equipment. In addition to numerous small craft bays, there are two docks for larger ships, such as [[freighter]]s, or even [[UNSC frigate|frigates]]. These docking bays could possibly be used to hold [[GA-TL1 Longsword|Longsword fighters]] used to protect the station from hostile spacecraft. The design incorporates many features against potential hostile boarding action, including security stations and small arms racks situated at strategic locations.<ref name="armory">'''Halo 2''', campaign level ''[[The Armory]]''</ref> | |||
=== | ===Armament=== | ||
The primary and crucial armament is a Mk. V "''Super''" [[Magnetic Accelerator Cannon]] capable of causing near-fatal damage to even a shielded Covenant capital warship with a single slug. The slug can weigh up to 3,000 tons and is launched at 4% the speed of light,<ref>'''[[Halo: The Fall of Reach]]''', ''page 283''</ref><ref>'''[[Halo: The Fall of Reach|Halo: The Fall of Reach (2010 edition)]]''', ''page 320''</ref><ref group="note">While the [[Halo Encyclopedia]] lists the velocity as 40% the speed of light, the figure remains unchanged in the reissue of ''The Fall of Reach'', a more recent source.</ref> ensuring the complete annihilation of the ODP's target.<ref name="armory"/> As with starship-mounted MACs, a platform's cannon is commonly controlled by an [[Artificial intelligence|AI]]. Due to the immense power of the MAC, a large recoil dampening system is situated at the base of the cannon.<ref name="cairo"/> Additionally, the platforms are armed with a number of [[point-defense gun]]s for close-in defense against enemy munitions, fighters, and boarding craft.<ref name="ciws"/> | |||
</ | |||
===Power plant=== | |||
ODPs do not possess the power generation equipment necessary to fire their main armament. Instead, they receive power from [[orbital defense generator|ground-based generators]]. An effective strategy to neutralize the formidable ODPs would be to disable the generators via ground assault. This would disable the platform's weaponry without destroying it, allowing this valuable prize to be captured or destroyed outright. The Covenant used this strategy during their invasion of [[Reach]], dropping troops to the planet's surface and destroying these generators. This paved the way for Covenant forces to completely overwhelm the UNSC forces in the space battle over Reach. | |||

Large numbers of UNSC forces were deployed to protect the orbital platforms' planetside power generators, but they ultimately fell against determined enemy assaults. The disabling of the defense platforms was a major factor on the battle's outcome.<ref>'''Halo: The Fall of Reach'''</ref> | ||

''[[Athens Station]]'' and ''[[Malta Station]]'' were each destroyed by [[antimatter charge]]s installed by [[Covenant]] boarding parties, while ''[[Cairo Station]]'' only narrowly avoided the same fate as the other platforms thanks to [[John-117|Master Chief]]'s [[Cairo Station (Level)|removal]] of the bomb on board.<ref name="cairo"/> The ODPs were used throughout the drawn-out Battle of Earth after [[Truth's fleet]] arrived, but the Covenant might have already destroyed numerous stations when Truth himself arrived at Earth on the [[Forerunner Dreadnought]] in November.<ref>'''Halo 3''', campaign level ''[[Crow's Nest (level)|Crow's Nest]]''</ref> | ||
During the [[Ur-Didact|Didact]]'s [[New Phoenix Incident|attack on Earth]] in mid-[[2557]], ODPs defended Earth from the Didact alongside the ships of the UNSC Home Fleet. However, the Didact's ship ''[[Mantle's Approach]]'' was too heavily shielded for even the ODPs Super MACs and as a result, the Master Chief had to destroy the ship from the inside with a [[HAVOK tactical nuclear weapon|HAVOK nuclear warhead]]. | During the [[Ur-Didact|Didact]]'s [[New Phoenix Incident|attack on Earth]] in mid-[[2557]], ODPs defended Earth from the Didact alongside the ships of the UNSC Home Fleet.

*All known orbital defense platforms over Earth are named after cities on Earth. It is also apparent that the stations' names are also based roughly on the region they orbit above: Cairo, Athens, and Malta, for example, are located rather close to each other geographically. However, the stations' locations do not directly correspond to the planetside locations of the cities, as the other stations in Cairo's battle cluster can easily be seen with the naked eye, whereas their namesakes are hundreds of kilometers apart. | *All known orbital defense platforms over Earth are named after cities on Earth.

*The fact that there are 300 ODPs orbiting Earth could be a reference to the [[Battle of Thermopylae]], in which 300 [[Sparta]]ns used the phalanx formation to hold their own against an army of more than 200,000 Persians. | |||
*Two weeks after the Fall of Reach, when the UNSC Security Council met at HIGHCOM in Sydney, it is mentioned by Colonel Ackerson that most of Earth's ODPs would take ten days before becoming fully operational. | |||
*The kinetic energy of a single shell from an orbital defense platform would be equivalent to almost''' '''51.6 gigatons of TNT, 1,031 times the yield of the real world's largest nuclear weapon currently tested. | |||
*The orbital defense platforms had entered the conceptual stage sometime around the 2490s, as [[Avery Johnson]] mentions that they were being proposed around the same time he shipped out for boot camp. | |||
