List of companies

This is a list of companies that operate primarily within UEG space.
===ABZ Raumschiffbau AG===
ABZ Raumschiffbau AG was a large spacecraft construction company that was founded in 2078. ABZ Raumschiffbau built hundreds of cargo ships, container ships, bulk carriers, and passenger liners from the 2080s until the company's cessation of operations in 2182. The company was one of several major backers of the anti-Koslovic movements that eventually merged with Freiden movement; ABZ Raumschiffbau contributed funds and spacecraft to the movement, as well as considerable technical assistance in converting commercial freighters into raiders and auxiliary cruisers. The company's involvement with the Frieden movement was discovered during the war. ABZ Raumschiffbau AG's business leadership were arrested and the company was effectively taken over by the UEG for the duration of the war. Following the Treaty of Callisto in March 2170, the investigation of the company was expanded massively. ABZ Raumschiffbau AG ultimately ceased commercial operations in 2180, and the company's remaining assets were liquidated by 2182, bringing an end to the 104-year-old shipbuilder. 
===Advanced Space Construction Corporation===
The Advanced Space Construction Corporation (ASC Corporation) was the largest spacecraft manufacturer in UEG Space from 2047 to 2101. Utilizing enormous orbital facilities near Earth, Luna, and later Mars, ASC Corporation played built hundreds of colony ships, cargo and passenger ships, orbital platforms, and space stations. The corporation was funded almost entirely through UEG and government contracts and was the principal shipbuilder of the colonization effort. Assisted by Titan Space Logistics, Inc. (TSL), the ASC Corporation was directly involved with major developments throughout the Sol System. 
Alongside building the first generations of colony ships, the ASC played a central role in the development of the mobile dockyard Stalwart Fortitude. Designated the ASC-X Keystone Platform during construction, the immense dockyard served as a mobile headquarters for early colonization efforts and, after being supplanted by the colonial flagships of the 2060s, remained a critical support structure for ongoing developments throughout the system. Outliving ASC, the UNOOSA, and the UNSA, the Stalwart Fortitude was only retired in 2293 and, even then, was repurposed as the central hub of the UNSC Martian Fleet Reserve. 
The ASC provided the Office of Outer Space Affairs with the bulk of its early space fleet: Earth One-class security battleships, Savoir Faire and Eurasia-class security ships, Observer-type surveillance craft, Safeguard ammunition carrier, Relay One-class communications ships, Dependable and Reliable replenishment ships, Exemplar missile testbed, and Paragon coil gun testbed. 
Much like TSL, the ASC Corporation was badly afflicted in the late 2080s and 2090s. The corporation was the largest shipbuilder in the system with hundreds of yards and tens of millions of employees, but a lack of forthcoming UEG colonization projects and colossal debts from previous colonization efforts meant that ASC was struggling to make payroll regularly. With growing competition from far more nimble shipbuilders (such as ABZ Raumschiffbau AG, Centurion Unlimited, Hayashi Spacecraft, Korolev Mondwerft AG, North American Superior, and SVR Shipyards) and facing an insurmountable solvency crisis, ASC attempted to restructure in early 2092, selling off assets and reducing headcount massively over eighteen months. Whole shipyards, engineering divisions, factories, workshops, and service yards were sold, as were ASC exclusivity contracts for colonial spaceports, warehouses, and waystations. Over a thousand colony ships of varying types and in varying stages of completion were sold. Many of ASC's chief competitors purchased distressed assets during this time, though most were sure to slightly overpay in order to stay in the good graces of the UEG. 
By 2094, ASC had halved its personnel and sold off a third of its 2091 assets. A second round of restructuring was initiated in late 2094: ASC's Martian and Jovian assets were sold off with nearly four hundred incomplete colony support ships being sold for scrap. The ASC maintenance fleet, already diminished, was sold in its entirety. A previously obscure corporation, the Vogt+Klein (VK) Industrial Group, purchased 90% of ASC's Cererian assets and approximately 40% of the Mars Division, as well as hiring more than seven million former ASC engineers. In 2096, ASC abandoned efforts at a new wave of colonization in the outer system, selling its remaining Saturnian assets and facilities to TSL (itself being owned and operated by the UEG by that time) and its remaining colonial support fleet. By 2097, most analysts were predicting a full collapse of ASC by the end of the year due to debts and poor profitability.

===Aldrin-Armstrong Company===
The Aldrin-Armstrong Company was a custom shipyard on Luna that operated during the Interplanetary Era. The Company was founded in 2108. Aldrin-Armstrong maintained an in-house development team that supplied unique designs for customers seeking distinctive spacecraft, especially yachts and corporate shuttles, and many of these designs were built by the company shipyard. In the late 2130s, several AAC architects participated in a series of conferences about the future of large spacecraft; during one such conference, the Aldrin-Armstrong contingent presented a work-up for a hypothetical battleship that measured 1,200 meters, carried an arsenal of missiles and naval batteries, and would traverse the system at considerable speed. The team developed the concept considerably over the next two years and ultimately put forward the 2141 battleship proposal for a high-speed 1,150 meter battleship. The design was well-received as technically impressive, but the UEG was not interested in further studies or construction of battleships at the time, and it was shelved as a historical footnote. 
In 2148, the Aldrin-Armstrong Company was contacted in secret by a then-unidentified potential client. The Company, which did occasionally make specialized ships for questionable clientele, was nevertheless surprised when the mystery client supplied their development team with several modified versions of the 2141 battleship proposal and requested extensive alterations to the design with varying specific objectives, such as orbital bombardment capabilities, expanded arsenals, greater speed, and better endurance. The Aldrin-Armstrong Company took the contract and ultimately produced a radical design for a 1,450-meter-long battleship in 2152. The mystery client accepted the design and revealed itself to be a government agency of the United Republic of North America, and immediately contracted Aldrin-Armstrong to build the battleship, preferably with some secrecy. While the Aldrin-Armstrong Company had never done anything to that scale or ever built a military spacecraft, company leadership was swayed by the largest contract of their careers and immediately began reconfiguring the company's shipyard for the task; the last AAC yachts were completed in November 2152, and work on the new battleship - nicknamed Eagle One - began in February 2153. 
Construction proved painfully slow, with the battleship less than 10% complete after a year; under pressure, the Aldrin-Armstrong Company embarked on a major hiring spree and quintupled construction staff in March 2154 alone. However, as construction progressed, both the engineering staff and the client made several major modifications to the design: an improved reactor design, more naval artillery and in more variety in that artillery, bigger crews to man the additional guns, more efficient engines, more lifeboats for the expanded crew, greater ammunition storage, a increase in length of 80 meters, increased armor for missile silos, better efficiencies in loading and unloading supplies and ammunition, removing over a hundred missile silos and replacing them with missile pods, a reduction in length of 53 meters, and finally several major changes in the layout of the engines and power supply. Company facilities grew expansively, increasing the size of the shipyard as support structures for the endeavor sprawled across the Lunar surface. Aldrin-Armstrong's massive hiring and huge expansion was anything but secret, and the clandestine battleship project was an open secret on Luna by 2156. 
The United Republic of North America acknowledged the project in April 2157 at the behest of the Unified Earth Government; the acknowledgement was made alongside an announcement that another Lunar battleship had entered the production stage. It was during these announcements that the Eagle One battleship project acquired the name "Armstrong"; the UEG made it official in 2158, listing the battleship Armstrong in a report about projected fleet numbers in the 2160s. With more funding that ever to complete the battleship, the Aldrin-Armstrong Company soldiered on, but were unable to complete the project before Apollo Shipyards completed their battleship, the Deep Tranquility, on December 21, 2164. Just eighteen days later, the Aldrin-Armstrong Company delivered the battleship Armstrong to the United Nations Space Command. The UNSC Armstrong was formally commissioned in May 2165 and took part in the Jovian Action in August of that year. The battleship would have a glorious if troubled career and would be the first battleship to be decommissioned by the UNSC in 2191 as a consequence of it uniquely difficult maintenance and overly complicated internal design. 
Even before the completion of the battleship, the Aldrin-Armstrong Company had begun working with Apollo Shipyards on the design and construction of five other battleships and several defense ships in 2161. Ultimately, both the Dominance and Intervention battleships were cancelled in 2162 and 2163, respectively, though the Company would deliver the defense ship Dragon in April 2165. Following the cancellation of the battleship Subjugator in the summer of 2163, both shipbuilders pitched a joint construction contract to the UNSA, just after the assassination in early November: elements of the cancelled battleships would be combined in order to produce a heavily discounted additional battleship for the fleet. As the system descended into greater chaos, the beleaguered UN Space Authority accepted the proposal. 
According to the official history, the 1,156-meter-long battleship Lunar Hero was accepted by the UNSC as an additional light battleship in 2167 and was judged to be a completely adequate warship of appropriate quality. Also according to the official history, the Lunar Hero was widely referred to as the "Frankenstein battleship", the Lunar Nightmare, and "Where maintenance crews go to die." Corporate memos from both Apollo Shipyards and the Aldrin-Armstrong Company routinely described it as "the freak battleship". Difficult construction aside, both companies were extremely well compensated for the battleship and the Lunar Hero remained in service until 2191, when it was decommissioned four months after the Armstrong. 
The Aldrin-Armstrong Company completed three more defense ships for the UNSC during the war: Thunderer in 2167 and Vengeance of Europa and Trident in 2168. The UNSC Thunderer was badly damaged during the Trojan Offensive in January 2170 and was scrapped a few months after the end of the war. The UNSC Trident succumbed to high maintenance costs and was decommissioned in 2198 and scrapped. The UNSC Vengeance of Europa remained in service until 2391, outliving the Aldrin-Armstrong Company by more than two hundred years. The defense ship was described as being of remarkably good design and impressively robust and was placed in reserve; the Vengeance of Europa was reactivated during the Human-Covenant War and took part in the Defense of Earth in 2552. 
For its part, the Aldrin-Armstrong Company was purchased by Apollo Shipyards in 2179 and functioned as a subsidiary until 2188, when it was wound down and integrated entirely into the Shipyards.

===Aligned Jovian Shipping Interests===
Aligned Jovian Shipping Interests (AJSI) was founded in 2118 and quickly established itself as a major commercial shipper in Jovian Space. 
*AJSI commercial fleet
===American Merchant Express===
American Merchant Express (AME) was a major freight company that operated a fleet of oversized cargo ships in the Sol system. Founded in 2115, the AME Group built its fleet and a reputation for reliability. Several AME ships were requisitioned by the UNSC during the Interplanetary War, with the majority returned to the Group in 2175. The American Merchant Express Group remained in commercial operation for centuries, eventually rebranding to simply AME in 2366. The company continued its freight business on an interstellar scale starting in the 2390s, though it was never able to attain a position of dominance in galactic shipping. Following the outbreak of the Human-Covenant War, the company steadily reduced its presence in the Colonies, with most of its interstellar fleet being handed over to the UNSC by 2536. A quintet of AME interstellar freighters remained in operation between Sol and Epsilon Eridani until the Fall of Reach in 2552; all five were present during the Covenant invasion, with three participating in evacuations in August, one lost at Tribute, and one lost at Reach. The AME interplanetary commercial fleet was not requisitioned for the most part during the Sol Campaign, though several ships were attacked by Covenant forces. AME survived the end of the war and resumed limited interstellar operations in 2556. 
AME ships that were requisitioned by the UNSC and served the fleet during the Interplanetary War: 
*AME1000 Freight Transporters (1,932 meters): AME Audacious, AME Fearless, AME Foresight, AME Forthright (irreparably damaged near Europa), AME Immaculate, AME Majestic, AME Patriotic, AME Perseverance, AME Prowess, AME Relentless, AME Resilience, AME Stalwart, AME Tireless, and AME Unflagging. 
*AME500 Freight Transporters (966 meters): AME Andalusia, AME Carrington (destroyed), AME Cortez, AME Delambre (irreparably damaged), AME Endiburgh (destroyed), AME Galveston (irreparably damaged), AME Greenland (destroyed), AME Guadalajara, AME Jerusalem, AME Juneau, AME Monarch, AME Pathfinder, AME Petropavlovskiy, AME Protectorate (destroyed), AME Sommerfeld, AME Tripoli, and AME Valencia. 
*AME500S administrative control ship (986 meters): AME Voyager. 
===Apollo Shipyards===
Apollo Shipyards was a massive Lunar shipbuilding company that was founded in 2109. From its humble origins as a colonial startup that produced passenger ferries and tugs, Apollo Shipyards grew into the largest shipbuilder on Luna with more than fifty shipyards in orbit. The company built eight battleships for the UNSC during the Interplanetary War; in the postwar era, Apollo Shipyards was recognized as the only credible rival to the system-dominant Superdreadnought Heavy Industries. 
Apollo Shipyards remained a favorite of the UEG during the 23rd Century, with the Lunar company benefitting massively from enormous government contracts for spacecraft of all kinds. During the doctrine disputes of the 2270s and 2280s, Apollo Shipyards gained additional political clout within the UEG following the company's refusal to build more battleships for the UNSC; after the Naval Compromise of 2290, the UEG effectively repaid Apollo Shipyards with contracts for support ships and colonial projects. 
Apollo Shipyards was heavily involved in the interstellar colonial efforts of the late 24th and manufactured ships of war for the Colonial Military Authority and the UNSC during the Inner Colony Wars. While the lunar company gained considerable experience with SFTE and interstellar ship construction during the crisis, Apollo Shipyards found itself financially overextended in 2415. With debts in the trillions of credits and the UEG struggling with even larger debts resulting from the fighting, Apollo Shipyards was forced to sell off considerable assets and seek investment wherever it could. In the process, the company was forced to reduced its workforce by hundreds of thousands. With no potential employers in the system capable of absorbing so many spacecraft specialists, the vast majority of ex-Apollo Shipyards employees elected to depart the system entirely and migrate to colony worlds where their skills were in high demand. From 2417 to 2427, the population of Luna declined by as many 7,000,000, with the collapse of Apollo Shipyards credited with primary factor behind the emigration. 
Apollo Shipyards emerged from a decades-long restructuring effort in 2437. The company still possessed considerable manufacturing facilities and forty-eight lunar shipyards, but most investors considered it to be living on borrowed time. In January 2439, one of the company's shipyards was totally destroyed when a colony ship experienced a catastrophic navigation error and collided with yard. While Apollo Shipyards was not at fault for the disaster, the financial cost of the incident was ruinous, and company was not expected to survive the year. It was under these circumstances that the leadership of Apollo Shipyards entertained an offer put forward by the two largest defense contractors in UEG Space: Misriah Armory and SinoViet Heavy Machinery. Under the terms of the offer, Misriah would purchase the manufacturing facilities on Luna and considerably overpay for them, as well as promise to keep factory personnel employed for at least two years; SinoViet would purchase the space yards and remaining Apollo Shipyards assets, and the company would become a SinoViet subsidiary for at least a decade. Rumors persist that the board of Apollo Shipyards accepted the offer by unanimous vote after just fifteen minutes of consideration. The deal was approved by the UEG within the year. 
Apollo Shipyards was retained as a subsidiary of SinoViet for next 151 years. SinoViet used the company primarily for specialty products and interplanetary craft, including interstellar shuttles. During the Human-Covenant War, more 10,000 Apollo Shipyards-produced shuttles were used during colonial evacuations and are estimated to have saved the lives of more than 100,000,000 UEG citizens.

===Archangel Designs & Construction===
Archangel Designs & Construction was Martian shipbuilder in the early 2100s. AD&C primarily built tramp freighters and other small cargo ships for commercial ventures with Martian Space from 2101 to 2143. In 2110, AD&C made a bid on a government contract to build a small defense ship for the Deimos colony which was accepted. Some historians have opined that AD&C had made their bid for political reasons as part of an effort for greater regional clout and had not anticipated their bid actually being accepted. This footnote aside, Archangel Designs & Construction completed the 275-meter-long defense ship in late 2115, and the UNSA Drake of Deimos was commissioned the following year. 
Following a slump in the demand for commercial freighters in the early 2140s, AD&C suffered financial collapse in 2143 and attempted several restructurings with the assistance of a number of external investors. After a little over a decade struggling and minimal success, the company was approached by a new shipbuilding company that was flush with cash: Superdreadnought Heavy Industries (SHI). SHI bought the company at a more-than-fair price, paid off its outstanding debts, and absorbed the assets of Archangel Designs & Construction, eliminating the company as an entity by 2154. AD&C's single warship, the Drake of Deimos survived the Interplanetary War and was decommissioned in 2173. 
*Drake of Deimos-class defense ship (2116)
===BRVK Group===
The BRVK Group was a massive megacorporation established in 2104 that specialized in heavy industry, especially in the design and manufacture of space weapons and spacecraft. The industrial giant was named for its founders - Brandt-Richter-Vogt-Klein - and constructed hundreds of manufacturing plants in the colonies and major shipyards in the vicinity of Luna, Mars, Ceres, Pallas, and Ganymede. In the 2140s, the BRVK Group designed and then produced the Berlin destroyers for the UN Space Authority. Originally envisioned as corporate enforcers, the class joined the fleet throughout the 2140s and 2150s, and saw considerable action during the Interplanetary War. 
BRVK was an early supporter of the Frieden movement and other anti-Koslovic organizations in the 2150s and early 2160s, quietly funding their operations until at least late 2167. The corporation also built as many as 50 raiding cruisers and 400 missile ships for the movement, as well as supplying the Friedens with hundreds of thousands of missiles, thousands of launch systems, ship system components, infantry weapons, artillery, and other vehicles and aircraft. BRVK engineers and specialists aided the Frieden movement in building munitions factories, shipyards, and foundries in Jovian Space. Only after the Frieden occupation of Juno and Ceres - actions that cost the corporation billions of credits - did the BRVK Group begin reducing its support of the Frieden movement. When the UNSC retook Ceres in 2168, the BRVK Group discovered that their facilities in the colony had been plundered and then destroyed by Frieden soldiers in order to deny their use to the UEG; this catastrophic damage proved too much for the corporation, and the BRVK Group drastically scaled back its support for the Europa-based organization. The involvement of BRVK in the funding and support of the Frieden movement was long suspected by the UEG but was only confirmed in 2169 after the seizure of damning documents on Europa. 
The BRVK Group escaped public exposure for its sinister dealings by virtue of being a major ammunition supplier, shipbuilder, and fundraiser for the UNSC: the corporation ranked in the top five defense contractors of the UNSC and was rumored to have provided the UEG with unprecedented lines of credit at very low interest rates. A prominent member of the UEG who was aware of BRVK's illicit dealings nevertheless referred to the corporation as "indisputably patriotic" for its unwavering support of the war effort in 2167; the Group was effectively insulated against backlash and was not even investigated for its activities until the turn of the century. 
The BRVK Group ultimately ceased operations in the Ceres Colony in 2168, selling their damaged assets to local interests. One of those local interests purchased and restored BRVK's shipyards with UNSC support, and founded the Cererian Shipyards just a month after the colony was liberated.

===Commando Cargo===
Commando Cargo was a significant colonial freight company that operated primarily in the Outer Colonies from its founding in 2411 until its acquisition by Kaiser Star Line in 2457. 
===Crazy Fox Express Shipping===
Crazy Fox Express Shipping was founded in 2404 as a miscellaneous freight transport company, essentially a tramp freighter company for colonial commerce. "Crazy like a fox; we'll ship anything!" The company's philosophy eventually ran afoul of the Insurrection, as Crazy Fox freighters (knowingly or not) transported cargos of ammunition, explosives, weapons, stolen materials, and military vehicles for various insurrectionist movements throughout UEG space. Despite its alleged involvement, Crazy Fox Express Shipping remained in service into the Human-Covenant War, ultimately surviving the conflict with a limited stock of tramp freighters and government and colonial contracts. 
===Diamond Division Special Service===
The Diamond Division Special Service (DDSS) was founded in 2541 as a specialty shipping company. The company operated a fleet of long-range armed freighters with sufficient endurance for journeying to the farthest flung Outer Colony and safely returning without refueling. 
===ELMAST Corporation===
Originally a subsidiary of the Interplanetary Material Transportation Corporation, the Earth-Luna-Mars Agriculture Specialty Transport Company was spun off in 2199 as an independent corporate entity. ELMAST, despite its name, provided foodstuff shipping to all regions of interplanetary Human space, including far-flung stations near Pluto and beyond. It remained the primary agricultural shipping firm of the Sol System well into the Colonial Era, only truly losing its dominance in 2427 as the Interstellar Shipping Service Company (ISSC) brought colonial agricultural products to Earth. Subsequently, in 2433, ELMAST partnered with the ISSC to consolidate and improve the food supply logistics system for the betterment of both companies and the populace of Earth. ELMAST ships would handle interplanetary transport of ISSC agro shipments that would be delivered to joint waystations located throughout the system. Additionally, ELMAST would provide the ISSC with vastly better access to Martian and Earth agricultural products for export to colony worlds. The Insurrections of the 2490s and beyond did little to impact the corporation; the onset of the Human-Covenant War in the 2520s did diminish the availability of colonial agricultural goods. Unlike the ISSC, ELMAST ships were not appropriated or requisitioned by the UNSC and UEG for military operations due to their interplanetary limitations. Only in late 2552 did the UNSC requisition freighters and stations from the ELMAST Corporation for the duration of the Sol Campaign.

Halifax Spacewerx was a major shipbuilder operating in the Inner Colonies from the early twenty-fifth century. 
*Phoenix-class colony ships
===Hayashi Spacecraft===
Founded in 2089, Hayashi Spacecraft was a Japanese spacecraft design and construction company that served the needs of the new United Nations Space Authority, developing and subsequently producing the Authority's first major warship class, the Kyoto destroyers, in 2096. Hayashi Spacecraft also built a number of destroyer tenders for the UNSA. 
*Kyoto-class light destroyers (2096)
===Interplanetary Material Transportation Corporation===
The Interplanetary Material Transportation Corporation (IMTC) was the largest shipping company in the Sol system for more than two centuries. 
===Interstellar Shipping Service Company===
The Interstellar Shipping Service Company (ISSC) was one of the big four freight companies (the others being Kaiser Star Lines, Monarch Transport, and Universal Conveyance) that dominated UEG shipping throughout the 2400s and 2500s. Founded in 2397, the ISSC was a sizable element of UEG logistics during the latter half of the Inner Colony Wars, transporting equipment and supplies primarily for the UNSC Army and UNSC Navy. This early success made a name for the company and gained it many friends in both the UNSC and the UEG. 
===Kaiser Star Line===
Kaiser Star Line (KSL) was part of the Big Four shipping companies (alongside the Interstellar Shipping Service Company, Monarch Transport, and Universal Conveyance) that dominated UEG space in the 2400s and 2500s. Founded on the Inner Colony world of the same name in 2386, Kaiser Star Line built an impressive reputation for reliability and safety in its early years, and extended that sterling reputation to companies it later acquired. KSL acquisitions included Commando Cargo (2457), Super Express (2486), and Kelso Passenger Services (2509). 
===Kelso Passenger Services===
Kelso Passenger Services (KPS) was the near-ubiquitous ferry company of the early Outer Colonies and also a major interstellar passenger transporter throughout UEG Space. Founded during the Inner Colony Wars as the "Kelso-Meyers Orbital Shuttle Company," the company was operating under the KPS name by 2400, and had ingratiated itself into the good graces of the Colonial Administration Authority. Long considered "too big to fail," Kelso Passenger Services encountered insurmountable financial trouble in the first decades of the Insurrection as the company was rocked by incidents, accidents, scandals, and persistent groundings due to local insurgency actions. The company was rescued from ruin by Kaiser Star Line, which acquired KPS in 2509. This rumored-to-be multi-quadrillion credit purchase is often cited as a critical development, as KPS ferries continued to be manufactured and maintained, and were a major component of colonial evacuations during the Human-Covenant War. 
===KMZ Freight===
KMZ Freight was founded in 2455 as the "Keller-Martinez-Zhou Freighter Company". 
*KMZ commercial fleet
*KMZ service flotilla
===Korolev Mondwerft AG===
Korolev Mondwerft AG (KMW) was founded in 2073 as a nascent Lunar shipbuilder. KMW built and maintained several shipyards and factories, building tugs, freighters, passenger liners, and shuttles, as well as patrol ships for the Space Authority. The most notable early patrol ship KMW built was the Solar Patrol, a high endurance long-range spacecraft that traversed the Outer System and even accompanied the 2162 Kuiper Expedition on its first phase. 
===Lucky Seven Shipping===
The Lucky Seven Shipping Company (L7S) was a shipping company founded in 2421. 
*L7 commercial fleet
*Lucky Star passenger liner fleet
===Lunar Freight Association===
The Lunar Freight Association (LFA) was founded in 2076. The Association started as a group of like-minded freighter captains and ground crews, and grew into a major shipping corporation that dominated Lunar logistics for more than a century. During the Interplanetary Conflict, the Association effectively donated around twenty ships to the UNSC for replenishment work. 
*LFA commercial fleet
===Monarch Transport, Ltd.===
Monarch Transport, Ltd. (MT) was part of the Big Four freight companies (alongside the Interstellar Shipping Service Company, Kaiser Star Line, and Universal Conveyance) that dominated UEG shipping during the 2400s and 2500s. 
===MQT Ships===
MQT Ships was a large shipbuilder during the twenty-second century, and was one of the major manufacturers based on Luna. Founded in 2134, its yards were producing passenger ships, cargo ships, and cargo liners by 2138. In 2160, several of their large passenger liners were converted into UNSA heavy carriers, collectively known as the Empress of Mars-class. MQT's shipyards suffered major damage during the Lunar uprisings and subsequent pacification campaign during the 2160a. While the firm survived the Interplanetary War, it was defunct by the 2190s. 
===North American Superior===
North American Superior was a heavy industrial corporation during the Interplanetary Era involved in many industries by especially in the design and construction of military and commercial spacecraft.

===Ringgold Space Freight===
Ringgold Space Freight was a sizable colonial shipping company that operated a sizable fleet of cargo liners throughout the inner and outer colonies. Following the razing of several human colonies in the late 2520s, the Ringgold family donated ships to the United Nations Space Command for use as evacuation transports. More than a hundred Ringgold cargo liners saw frontline service and saved millions of lives. Ringgold Space Freight remained active throughout the Human-Covenant War, and continued regularly to support UNSC operations and donate ships outright for use as transports.

===Super Express Shipping===
Super Express Shipping, often shortened to "Super Express" or even "SX", was a heavy freight company founded in 2437. While Super Express found considerable success in the heavy equipment shipping market, the company struggled due to a lack of strategic support facilities and the resulting months- or years-long servicing delays for their major ships. Following its acquisition by Kaiser Star Line in 2486, these problems effectively evaporated. Super Express provided UNSC logistics with invaluable support during the Human-Covenant War.

===Titan Space Logistics, Inc.===
Founded in the 2050s, Titan Space Logistics, Inc. (TSL) provided critical logistical expertise to the terraforming projects conducted throughout the Sol System from the 2060s to the late 2080s. While the achievements of the TSL were considerable, the additional development of the Jovian colonies and asteroid settlements pushed the company almost to bankruptcy by the close 2096. Given that TSL, Inc. fleet was still engaged in supporting colonial development in the system, and no firm of similar size or capability existed, efforts were undertaken by the Unified Earth Government to effectively bailout the entire company in February 2097. Despite this considerable assistance, as colonial development stalled in the first decade of the twenty-second century, Titan Space Logistics, Inc. again found itself facing financial ruin as maintenance costs were high and project paydays became fewer and fewer. The company was therefore sold entirely to the Interplanetary Material Transportation Corporation (IMTC) with the blessing the UEG on April 2, 2106. TSL, Inc. remained an IMTC subsidiary for the next two hundred and fifty years, briefly returning to prominence during the rebuilding following the Interplanetary Conflict.
===Trojan Resources===
Trojan Resources (TR) was founded in 2088. The corporation managed mines and manufacturing facilities in the Jovian Trojans, as well as operating a fleet of mostly freighters and other ships in Jovian Space. Despite its apparently warm relations with the Frieden movement, the corporation had a considerable number of UEG loyalists in its ranks. Following the effective takeover of the Trojans by the Frieden movement in late 2163, elements of Trojan Resources plotted to escape the occupation. When the UNSC unsuccessfully attacked the Trojans in September 2165, TR loyalists made their attempt. Seventy-two TR ships attempted to flee from various colonies, and fifty-seven of them made it away safely. Fifteen were captured or destroyed, and the remaining TR ships in the Trojans - more than a hundred - were seized by the occupiers. Of the fifty-seven to successfully escape, thirty-five were handed over to the UNSC and became twenty-eight replenishment ships, three salvage ships, two repair ships, and two transports. Frieden-seized TR ships suffered heavy losses during the UNSC's 2170 Trojan Offensive. The corporation very nearly disintegrated during the war, and its facilities, factories, and ships were various damaged or destroyed. 
Nevertheless, Trojan Resources returned to prominence after the war, buoyed by UEG contracts and the massive rebuilding effort in Jovian Space. Following the population decline in the Trojans in the 2370s, Trojan Resources began downsizing its operations accordingly. By the 2450s, the corporation was a shadow of its former glory, and most of its facilities were empty or mostly unused. One again, Trojan Resources very nearly dissolved when a failed investment left the corporation in the red on April 11, 2456. Supposedly only eighteen hours away from bankruptcy and financial collapse, the board of Trojan Resources was approached by a most unexpected would-be client: the Office of Naval Intelligence. ONI wanted use of the company's facilities throughout the Trojans, and wanted Trojan Resources to resume managing and maintaining those facilities properly. The board readily agreed to ONI's terms, and Trojan Resources was back in the black by the end of the year. 
Trojan Resources continued mining for rare materials, most of which went to the UNSC; ONI's presence was minimal until 2478, after which it grew continuously. UNSC forces were firmly entrenched in the Trojans by 2520, and defended the colonies during the Covenant invasion of the system in 2552. 
===Universal Conveyance===
The Universal Conveyance corporation, founded in 2378, was part of the Big Four freight companies (alongside the Interstellar Shipping Service Company, Kaiser Star Line, and Universal Conveyance) that dominated UEG shipping during the 2400s and 2500s. Often considered the favored son of the Colonial Administration Authority, Universal Conveyance operated an enormous fleet of container ships for Authority projects.
