The United Nations Navy (UNN) is the naval branch of the United Nations military. It is considered less technologically advanced than the Martian Congressional Republic Navy (MCRN). However, it has the largest fleet in the Sol system and is generally considered to be the overall superior of the two.
Overview[edit | edit source]
Earth’s military, primarily the United Nations Navy (UNN) and the United Nations Marine Corps (UNMC), are arguably the most powerful combined military force in the system. Most of the UN Navy is spread throughout the Solar system, overseeing and protecting Earth's interests in the Belt and the Outer Planets or keeping the peace as part of the Earth-Mars Coalition Navy.
While not as technologically advanced as the MCRN, the United Nations Navy is considerably larger, consisting of capital ships such as Dreadnoughts and Battleships, as well as smaller vessels like Cruisers, Destroyers, Frigates, Corvettes, Patrol Torpedo boats, and Fleet support ships. Nevertheless, projections have shown that the technological superiority of Mars would give them an edge against UNN numbers in any major conflict between the two planets. The United Nations Marine Corps serves aboard UNN vessels and guards UN outposts in the Belt and beyond. Marines wear vacuum-rated and radiation shielded Reaver powered armor, enabling them to engage in combat operations virtually anywhere in the system. The UNMC can place over 100 million troops on the battlefield at a given time, far outnumbering the ground forces of any other nation including Mars, and the fact that UN marines are born, raised, live, and train in the full gravity of Earth, gives them a considerable advantage against opponents accustomed to the lower gravity of Mars or the Belt.
Structure[edit | edit source]
The exact structure and ranking system of the United Nations Navy remain largely unknown.
However, according to on-screen information, the UNN is headed by the Fleet Admiral (a 4 or 5 star Admiral), who is the senior-most member of the Navy and has a seat in the United Nations Security Council.
The Navy itself is divided into several established fleets, each commanded by an Admiral. Each fleet has its assigned area of responsibility. For example, the Third Fleet's area of responsibility is Jupiter and its moons; hence, it's known as the "Jupiter Fleet". However, in times of war, this division becomes rather fluid. For the purpose of executing various missions, the Navy creates temporary units of lesser size, which may consist of ships from different fleets - these units are called Task Forces. One example is the Thomas Princes Task Force - a unit of the UNN which was created for the sole purpose of traveling to the Ring, and later into the Slow Zone itself.
UNN rank structure is somehow unclear due to noticeable differences between that and 21st century navy rank insignias but, it generally resembles the structure and insignias of western nations' navies.

History[edit | edit source]
Eros Incident[edit | edit source]
When the Donnager is destroyed by what is believed to be OPA ships, and Mars declares war on the Belt, the the UN stays neutral. Later when Holden released information on the ships that destroyed the Donnager were actually made on Earth, UNN ships fired on Martian Congressional Republic Navy ships in Mars' orbit and destroyed the Deimos deep radar station. After securing Martian space, the UNN begin laying siege to Mars, forcing, the MCRN then orders nearly all their ships in the system to return to Mars and declares war on Earth. The Belt claims it a victory, and the siege lasts for months. However, all combat remains in orbit and doesn't spread onto Martian soil.
The Charles Lyell, a science vessel, escorted by the Ravi, was doing a non-Belt asteroid mapping when it was diverted to Eros to collect samples of the Protomolecule. It was in a confrontation with the Rocinante until they finally worked together to stop the asteroid.
Ganymede Incident[edit | edit source]
The Ganymede incident was an event where a human-protomolecule hybrid attacked Martian and UN Marines on Ganymede, killing everyone except Gunnery Sergeant Roberta Draper. The initial attack was misinterpreted by both the MCR and the UN as an attack from the other side, which lead to a battle above and on Ganymede that claimed nearly three thousand military and civilian lives, as well as over five billion MCR dollars of infrastructure damage.
[edit | edit source]
Laconian Dominance[edit | edit source]After the defeat to the Laconian Imperial Navy the UNN was still permitted to operate as part of the Earth-Mars Coalition Navy in policing operations in the Sol system.
Prior to the Eros Incident[edit | edit source]
The UNN detected the battle between the Donnager and unknown stealth vessels, although a powerful jamming in the area prevented precise readings. UNN Commander, Admiral Souther, dispacted a warship to find out what was going on, but by the time it got there it was to late to assist the Donnager. Unbeknownst to them, James Holden and his crew survived the battle by fleeing in a Martian Corvette.
Eros Incident[edit | edit source]
When the UN found out about Eros moving towards Earth, the UN & UN Navy leadership decided to contact a ship that was there not knowing that the Captain was in fact James Holden working with the OPA faction of Fred Johnson. He persuaded them to launch long range nuclear missiles and that Fred Johnson could be trusted.
Ganymede Incident[edit | edit source]
Slow Zone Incident[edit | edit source]
The UN send a flotilla to the Sol gate with many religious leaders onboard the flagship Thomas Prince. When the ring gate activated and the three fleets moved into it the Secretary-General of the United Nations ordered that all civilians onboard leave on a vessel headed elsewere in the sol system.
[edit | edit source]
When Earth was struck by two stealth coated asteroids parliament member Chrisjen Avasarala convinced Nancy Gao to connect the asteroid spotters to the defence network to detect further asteroids. Nancy ordered this, however it was too late to save herself as whilst she was onboard Un One a third asteroid impacted the Indian ocean near her location. Her plane and its escorts were hit by the blastwave knocking them out of the sky and killing all onboard.
David Paster was the highest surviving member of parliament and became acting Secretary General. He knew he was unsuited to the role and asked Chrisjen Avasarala to serve on his council. During a meeting Admiral Felix Delgado recommended a strike on Pallas as it contained high Marco Inaros supporters. Chrisjen opposed this however as this was a civilian target and would only radicalise the entire Belt against the United Nations.
David Pastor authorised a strike on Pallas behind the back of Chrisjen anyways hitting the station with many civilian casualties. Chrisjen Avasarala protested this and when became clear that David Pastor was more interested in attacking Belters in retaliation strikes she resigned from her position, refusing to be any part of it. A further three ministers then also immediately resigned along side her.
Later four more ministers resigned from his cabinet and those remaining made a Vote of no confidence in David Pastor removing him from his post and electing Chrisjen Avasarala to be Secretary-General of the United Nations.
Upon her swearing in Chrisjen Avasarala declared martial law on Earth and Luna during the crisis and announced that there would be no strikes against any of the loyal civilians of the Belt and outer system.At the begining of the Free Navy Conflict the UNN consisted of at least twenty-two battleships including at least sixteen Leonidas-class ships docked on Luna, and at least six Truman-class ships, of which two were destroyed at the Battle for the Sol gate.
Notable personnel[edit | edit source]
- The former leader of the Outer Planets Alliance, Fred Johnson, was formerly a colonel in the United Nations Marine Corps, where he gained infamy throughout the system as the “Butcher of Anderson Station.”
