In the 2600s, the Human species occupies a large territory comprised of dozens of independent colonies with Earth at its center. Humanity has fully colonized the solar system and has expanded into interstellar space, claiming a myriad of alien worlds as their own. Their sphere of influence extends seventy light-years in all directions from Sol.
The dominant power in Human space is the United Nations, an intergovernmental organization that represents member states and colonies. The primary goal of the UN is the establishment of diplomatic relations and trade between the often disparate colonies, as well as ensuring peace and security through their military branch, the United Nations Navy.
United Nations Navy
The UNN is the military branch of the United Nations. It began as a simple peacekeeping force that was necessary to police interstellar space where no single nation or colony had the capacity to do so alone. After the outbreak of the Betelgeusian war in 2598, and with individual states and colonies expanding their space forces, the UNN took on a more direct military role in the protection of Human territory.
The UNN is not the monolithic force it is often portrayed as but is rather a coalition of independent navies who pool their resources to create a larger fleet capable of defending such an expansive territory. Prior to the Betelgeusian war, Human powers such as the United States, Russia, and Mars were already updating their navies and drafting new designs to better protect their interests on the interstellar stage. After the outbreak of the war, Humanity faced a genocidal threat and was suddenly thrust into a Galaxy where rival species with far greater military capabilities were operating. This created an attitude of unprecedented solidarity in which technology was shared between nations and standardized designs were drafted.
During this period, the construction of new, modernized spacecraft was undertaken on a large scale, with different nations and colonies funding one or more fleets with the newly-minted Jump Carriers at their center. Each fleet is controlled by a nation or colony, some fielding larger forces than others.
As time went on, the nature of large-scale international operations coordinated over light-year distances necessitated closer cooperation between the fleets, as well as the standardization of tactics and weapons. Before long, the Admiralty was formed, a command organization pulling from some of the greatest military minds of the various member states. The Admiralty was granted control over the UNN, which allowed the organization to operate as a single cohesive force.
Branches of Government
The United Nations is separated into three distinct branches, each with its own responsibilities and decision-making power.
The first of these is the General Assembly, the main deliberative organ of the United Nations and the seat of civilian power. It is comprised of representatives from all member states, each of which has one vote. Operating beneath the General Assembly are various other specialized councils, such as the Security Council, the Court of Justice, and the Secretariat.
The Admiralty is made up of prominent military leaders who are appointed to the position by their respective states. The War Powers act of 2598 affords them a great deal of control over the UNN’s fleets, and a degree of autonomy in their decision-making that allows them to be flexible and reactive to emerging threats. The Admiralty convenes to vote on the joint operations undertaken by fleets. Admirals are also appointed to oversee the operations of naval installations, and the UN’s seat on the Coalition Security Council is filled by one of the Admirals.
Coalition Security Council
The CSC is the decision-making body of the Coalition, and the UN is bound by the responsibilities outlined in the Coalition charter. The UN is also obligated to comply with CSC decisions, which are decided by a majority vote.
UNN Marine Corps
In the era of interstellar conflicts, the relevance of national armies began to wane, as they were unable to operate effectively without a supporting navy to transport them to where they were needed. This resulted in the Interstellar Warfighter initiative that was intended to create a next-generation fighting force. Training conducted between militaries from different states under this initiative evolved into the UNN Marine program, an attempt to create a truly space-based military organization. This was expanded to encompass all of the responsibilities of traditional armies, including ground-based armor, logistics, and infantry.
While some nations still operate their own military forces, the UNN Marine corps makes up the vast majority of the UNN’s fighting force. When other organizations participate in battle alongside them, they usually take the form of special forces units and other more specialized teams.
UNN Marines are equipped with standard-issue battle armor. This armor is rated for vacuum and can protect the wearer from chemical agents or hostile environments for as long as the suit’s battery lasts. The ceramic plates are designed to absorb the energy of a plasma bolt and spread it over a wider area, reducing its ability to penetrate, and their angled shape is effective at deflecting shrapnel. The helmet incorporates a HUD that can link with weapons systems, showing targeting data, battery charge levels, and ammo counts. Cameras mounted in the helmet can also broadcast a live feed that can be shared with squadmates or superiors. The suit’s functions and onboard computer can be controlled via touch panels on the wrist or the side of the helmet. It also incorporates electromagnetic pads in the boots that allow the wearer to walk in a microgravity environment, such as a ship with a damaged AG system or the outer hull of a vessel.
Planetary Defense Force
The Planetary Defense Force is made up of military reserve forces and colonial militias tasked with defending planets from invasions and policing their local territory. Their jurisdiction extends to a single planet or solar system.
Despite the immense size and manpower of the UNN, it can be logistically impractical to get fleets to where they need to be on short notice, if not impossible. For this reason, many colonies, especially those in outlying systems on the frontiers of UN space, must rely on their own populations to hold off potential attacks until UNN reinforcements can be dispatched. Due to the length of time it can take vessels to cross interstellar distances, PDF may be expected to hold out for weeks or even months with only the resources and equipment they have on hand. This has resulted in many population centers, especially frontier worlds, employing elaborate systems of bunkers and forts to keep their population safe if such an attack should occur.
The PDF have a reputation for being underequipped and poorly trained, but this is not always the case. While some PDF units are equipped with modern armor and XMR platform weapons, most use caseless weapons that are considered last-gen, and their access to armored vehicles is similarly restricted to older platforms that may no longer see widespread use. Many PDF units have access to STS missile systems used to attack targets in orbit, and more recently, MAST systems have been delivered to many outlying colonies. The MAST was developed as an interdiction weapon designed to cripple Betelgeusian fleets in orbit. It is a form of ASAT missile that launches a swarm of tungsten penetrators, making it very difficult for point defense weapons to defeat. These weapons are mostly intended to be used as a stopgap measure to buy time for reinforcements to arrive.
Police actions undertaken by the PDF involve customs and immigration, law enforcement, and anti-piracy operations.
United Nations Naval Intelligence
UNNI is the intelligence branch of the United Nations Navy, officially tasked with gathering, processing, and analyzing security information from across UN space, primarily through the use of human intelligence (HUMINT). UNNI reports directly to the Admiralty and is authorized to carry out and oversee covert actions at its behest, including surveillance, paramilitary operations, counter-terrorism, and cyber operations.
UNNI agents (often referred to colloquially as Ninnies) have access to cutting-edge technology that is often experimental in nature, leveraging this advantage to stay ahead of their enemies. Their operatives are highly-trained and are skilled in both combat and infiltration.
UNNI is often viewed with a certain degree of mistrust and distaste by other branches of the Navy, with their allegiance and loyalty to their fellow servicemen frequently brought into question. They are seen as ruthless and manipulative, which may very well be traits valued and sought out by the organization. SWAR has an especially strong rivalry with UNNI, as their methods and values are diametrically opposed, sometimes bringing them into conflict.
Special Weapons and Advanced Recon
SWAR is an offshoot of the Interstellar Warfighter program, a special forces branch that operates under the authority of the Admiralty. The organization’s main functions are conducting small-unit special operation missions in hostile or sensitive environments that are unsuited to Marine units. SWAR teams are typically ordered to eliminate high-level targets, sabotage enemy infrastructure, or gather intelligence behind enemy lines, leveraging their technological edge and mobility to succeed where conventional forces might not.
SWAR is unusual in that they only recruit veterans who have suffered amputations due to battlefield injuries. Operatives make extensive use of cybernetic enhancements, favoring quadruple-amputees, where all four limbs can be replaced with advanced prosthetics that make them more effective fighters. This may be an attempt to get around the Yellow Sea Treaty, which prohibits the augmentation or the alteration of the human body for the purpose of warfare by way of cybernetics, genetic engineering, or indoctrination. The amputation of a healthy limb or the removal of a functioning organ to be replaced with a prosthetic equivalent is prohibited by UN law, and such surgeries can only be performed for valid medical reasons. This does not change the fact that cybernetic technology has many advantages that could be leveraged by the more unscrupulous elements of the UNN, however.
SWAR teams have access to cutting-edge equipment and are afforded a great deal of autonomy when it comes to approaching a mission. They commonly make use of Coursers that have been modified for stealth and equipped with shipboard weapons, leveraging their speed and small profile to infiltrate enemy territory. Deployment to the ground happens either by shuttle when the tactical situation permits, or by drop pod. Drop pods are small, compact capsules that are able to accommodate three passengers, and are able to make landfall under their own power using a combination of retro thrusters and aerobrakes.
The UNN makes extensive use of alien auxiliaries in its forces, forming integrated, multi-species units. The UNN is largely responsible for training and outfitting auxiliaries, ensuring that they are able to meet the standards required by the organization.
Borealan Shock Troopers
Borealan Shock Troopers are most commonly used as their name implies, spearheading assaults and leading boarding operations where their natural aggression and strength can be leveraged to devastating effect. Their keen senses also make them excellent trackers.
Shock Troopers wear a variant of Marine armor with all of the same protections and capabilities, and are often equipped with large frame XMR variants. On their native planet, Borealans make extensive use of powder rifles that resemble muskets, making them well-suited to long-barreled, semi-automatic weapons. These rifles are commonly equipped with bayonets for use in CQB.
Borealans operate in packs of between four and eight that are often designated by UNN commanders using the Greek alphabet. They are fierce warriors with a strong concept of duty and honor, and will fight to the death if orders are not given to retreat. Despite their reputed aggression, they can be cautious and methodical when required, with Elysian Rangers and Araxie making especially successful scout snipers.
Krell Linebreakers are heavy infantry equipped with light machinegun variants of the XMR platform and other heavy weapons. They make use of heavy armor modeled after UNN bomb disposal suits, supplementing the already impressive survivability of the Krell to make them highly resistant to damage. They are used to counter enemy assaults, to reinforce the line, or to defend key strategic positions. Marines often describe them as mobile pillboxes, providing covering fire as other squads maneuver around them.
The Krell are known for their loyalty and devotion, often putting themselves in danger to rescue a wounded comrade, which has earned them a great deal of respect and admiration. Units that include Krell have markedly higher survival rates than those who do not.
While usually good-natured, Krell are capable of entering a state of enhanced metabolic activity known as a frenzy when provoked, making them especially destructive in close quarters.
Valbaran Commando units are disciplined and coordinated, their speed and reflexes making up for their relative lack of stamina. They are highly trained when compared to other auxiliaries, and are one of the few Coalition species that operates a modern, professional military.
They are often equipped with small frame XMRs in PDW variants but sometimes favor their own laser-based weapons systems, especially when it comes to sidearms. Commandos wear their own armor, which has similar capabilities as that used by Marines, albeit being more lightly-armored.
Valbarans are suited to most battlefield roles, but their small size and lack of stamina mean that they should be supported by vehicles where possible, as marching over any significant distance will exhaust them. Native Commando tactics favor vehicle-based striking and fading, deploying from dropships or personnel carriers to overwhelm the enemy with precision assaults.
UNN fleets make use of many spacecraft variants in their operations, combining different specialized craft to maximize their flexibility.
Assault Carriers are transport vessels that carry armored battalions to and from combat zones. The bulk of the vessel is taken up by the garages, where up to 150 vehicles can be carried. 136 vehicles constitute one UNN armored battalion.
The vehicles are arranged in rows six long and five deep in five tiered garages which are accessible by elevators located towards the bow. The vehicles are attached to trolleys that operate on a sliding rail system that allows fast, easy transport. Towards the stern are a pair of clamshell doors that open to expose the docking ports at the rear of the hangar to space, allowing specialized landers to dock and receive vehicles directly. They connect to the rail system, allowing the vehicles to slide into their bays on their trolleys, making the process of loading and unloading vehicles extremely quick and efficient. These dropships remain docked inside the protective doors during transit, and up to 25 can dock at once.
Due to the presence of the docking ports at the stern, Assault Carrier engines are mounted on nacelles that extend from the port and starboard of the ship. There is a secondary hangar for shuttles and troop transports situated closer to the bow, just behind the bridge.
Along with an armored battalion, an Assault Carrier can accommodate up to 3000 UNN Marines and personnel.
Assault Carriers are named after historical invasions, such as the UNN Okinawa or the UNN Overlord.
Mass: 39,000 tons
Armament: 2x defensive CIWS guns
Beewolf Space Superiority Fighter
The Clovis frigate is a common sight in UNN space, and often makes up a large part of a carrier’s escort fleet. At two hundred meters, the Clovis is small when compared to cruisers and battleships, but it packs a lot of firepower, able to field sixteen railguns and eighteen missile bays. The sleek, streamlined hull is designed to reduce the vessel’s radar cross-section and is painted with a black coating that absorbs RF radiation. The ship is defended by four CIWS guns, and all of its armaments can retract into the hull during silent running.
The ship gets its name from the Clovis point arrowheads that share a similar profile, a common Native American archeological artifact frequently found in North America.
UNN frigates are usually named after war heroes from their respective country or colony, such as the UNN Baskeyfield or the UNN Rubin.
Mass: 20,000 tons
Armament: 16x railguns, 18x missile bays, 4x CIWS guns
Coursers are small vessels designed for maximum speed and efficiency, with the ideal ratio of mass and energy output to make long-distance superlight jumps. They’re most commonly used to transport VIPs, to carry important messages where no quantum uplink is available, and as transportation for special forces teams.
Coursers are made up of two modules that are connected via a skeletal gib that runs between them. At the bow of the vessel are the bridge, a limited cargo bay, and a crew module where crew and passengers can live during transit. At the stern are the reactor room, and the engine module. The hull is sleek and streamlined, often described as needle-like.
Being too small to have an onboard hangar, personnel transfers on Coursers usually happen via docking umbilical.
The Doloto-class Torpedo Frigate is the UNN’s primary missile platform and is a mainstay in the Navy’s carrier escort fleets. Equipped with twenty-four missile bays, two defensive railguns, four CIWS turrets, and twelve launch tubes that can accommodate larger torpedos, the Doloto is a force to be reckoned with. The Doloto can carry up to 1200 tons of ordnance in its launch tubes and is able to accommodate projectiles with a length of thirty feet and a mass of up to 100 tons. These include nuclear warheads, MAST ship-killers, and long-range smart torpedoes. With a length of 200 meters, and a hull designed to deflect radar and absorb RF radiation, the Doloto can be very difficult to detect, especially at ranges where it can jump to a new position after firing a spread of torpedoes.
Originally a Russian design, the Doloto gets its name from the Russian word for chisel due to its shape.
UNN frigates are usually named after war heroes from their respective country or colony, such as the UNN Baskeyfield or the UNN Rubin.
Mass: 25,000 tons plus 1200 tons of ordnance
Armament: 24x missile bays, 12x torpedo tubes, 4x CIWS guns
Jump Carriers are the flagships of the UNN fleets and are arguably the most important vessel on the field. They spearhead planetary invasions with their large crew complement and their squadrons of spacecraft, they provide ground support using their ventral railgun batteries, and they pull fleets along with them into superlight. They’re also capable of resupplying their support fleets with fuel and life support on long deployments.
Jump Carriers are four hundred meters long, making them one of the largest classes of UNN vessel. Armed with arrays of railgun batteries, dozens of torpedo tubes, and thick armor plating, they make formidable adversaries and are very much capable of both defending themselves and participating in ship-to-ship combat. The raised bridge is mounted atop the vessel, providing good visibility to the bridge crew, while the observation deck mounted beneath the vessel allows for observation and direct fire when the carrier is in orbit of a planet.
The vessel is able to carry a contingent of 6,000 to 10,000 UNN Marines and can deploy them directly to a planet’s surface using a fleet of troop transports that are launched from its hangar bays. These are large flight decks situated on the port and starboard of the vessel which are open to space, the atmosphere contained by molecular force fields.
Along with its contingent of Marines, the vessel can carry between 60 and 90 craft of varying types, including Beewolf superiority fighters, Penguin gunships, and troop transports. They are equipped with 40 launch tubes which can be loaded with either Beewolf fighters or troop transports, allowing up to 40 craft to be launched immediately upon exiting superlight, while up to 8 craft can be launched at once from the hangar bays (4 per bay). This can somewhat complicate rearming and refueling.
Jump Carriers get their name from their ability to make long-distance superlight jumps due to their six onboard reactors, pulling nearby vessels along with them. While all UNN vessels large enough to accommodate a nuclear reactor can make superlight jumps, their respective mass and power output dictate the distance traveled. Jump Carriers bypass this limitation by capturing the fleet in its superlight wake, a spherical manifold that extends some distance around the ship, ensuring that the entire fleet travels the same distance with each jump.
Jump Carriers and other UNN ships use water to cool their reactors, which is heated to the point that it undergoes a process known as thermochemical cracking. The oxygen and hydrogen molecules are separated, then harvested to be used for life support in the case of oxygen, and chemical propellant in the case of hydrogen. As long as the carrier has access to water ice, which is a very common resource in solar systems, it can sustain itself and its support fleet for long periods of time during a deployment. Reactors can be ejected from the vessel in the case of damage or a meltdown in a process known as a core dump.
The vessels are able to make landfall if necessary and are capable of limited atmospheric flight.
Jump Carriers are named after famous last stands from their respective nations or colonies, having been commissioned at the beginning of the Betelgeusian war, such as the UNN Shiroyama or the UNN Thermopylae.
