UNSC order of battle on 26 December 2163

On December 26, 2163, the fleet of the newly inaugurated United Nations Space Command (UNSC) numbered 10,882 commissioned spaceships: 790 warships, 5,618 patrol vessels, and 4,474 auxiliaries. Another 521 spacecraft were under construction: 107 warships, 175 patrol vessels, and 239 auxiliaries. 
The UNSC Armed Forces had approximately 201,193,000 personnel. The UNSC Navy had about 795,000 personnel and the UNSC Marine Corps possessed some 86,500 marines. With the UNSC given authority over UEG terrestrial forces, the UNSC had approximately 200,311,000 military personnel in aviation, ground, and maritime roles throughout the Solar system. 
The UNSC Space Fleet comprised: 
*32 carriers, with 14 heavy carriers, 6 assault carriers, and 12 light carriers in commission. 6 Endurance-class heavy carriers, 5 assault carriers, and 16 Spirit-class light carriers were under construction, and more of each type was on order; 
*15 battleships in commission, all of them defense ships. Twelve more battleships were under construction, with 1 super-heavy battleship, 5 heavy battleships, 5 light battleships and the defense ship Dragon in varying stages of completion; 
*59 cruisers, with 2 super-heavy cruisers, 16 heavy cruisers, and 41 light cruisers in commission. Another 9 heavy cruisers and 7 light cruisers were under construction; 
*575 destroyers, with 14 super-heavy destroyers, 225 heavy destroyers, and 336 light destroyers in commission. Another 5 Rio de Janeiro-class super-heavy destroyers, 9 heavy destroyers, and 26 light destroyers were under construction; 
*109 frigates, with 72 heavy frigates and 37 light frigates in commission. Another heavy frigate and 15 light frigates were under construction, with many more Trondheim-class light frigates on order. 
==Order of battle==
On December 26, 2163, UNSC forces were divided between three sectors and two commands, with the lion's share of assets being split between Earth and Mars. 
===UNSC Earth Sector===
UNSC High Command was based on Earth and had effective control of forces within the Earth Sphere or Earth Sector. Space assets were locally controlled, assigned to the Lunar Flotilla, or part of the Home Fleet. Ground, aviation, and maritime forces on Earth were stronger than in any other place in the system; UEG home field advantage was unmatchable, especially after the Rainforest Wars badly depleted the forces of the Frieden and Koslovic movements on Earth. The same conflict had supercharged recruiting efforts on Earth and in December 2163, there were approximately 179 million personnel under the banner of the UNSC, with millions more in training. The UNSC Marine Corps was barely present on Earth with just 2,000 marines active, with almost all of them involved in recruiting and training. 
====UNSC Home Fleet====
The UNSC Home Fleet possessed 5 carriers and 11 cruisers. 
*4 heavy carriers and 1 assault carrier
*1 super-heavy cruiser, 3 heavy cruisers, and 7 light cruisers
====UNSC Lunar Force====
Due to the violence of the last two years, more than two million UEG troops were garrisoned on Luna on December 26, 2163. Another 18,000 UNSC marines were present as well. The UNSC possessed more than a hundred defense installations, fortifications, and training facilities on the Moon. The UNSC Lunar Flotilla comprised destroyers and defense ships. 
===UNSC Mars Sector===
Second only to Earth in terms of available military assets, UNSC Mars Command possessed considerable ground and space forces. UEG troops and UNSA space forces had just concluded a massive shock offensive against Koslovic forces concentrated in the Argyre Planitia on Mars that had lasted seventeen days; following the declaration of victory on December 25, the United Nations Space Command had been formally inaugurated with UEG-authorized authority over both space and terrestrial assets. Thus UNSC Mars Command possessed a terrestrial army of some 17 million personnel and a naval fleet of more than a hundred ships. Approximately 57,000 marines were present on Mars, including the majority of the UNSC's Orbital Drop Shock Troopers; the ODSTs, as they came to be known, had spearheaded the assault on Koslovic forces. 
Despite these impressive resources, the situation was hardly comfortable for UNSC commanders: both Frieden and Koslovic forces remained active across Mars, and information on their numbers and equipment was practically nonexistent. Additionally, immediately prior to the arrival of the Expeditionary Fleet, the Frieden movement deployed considerable assets to the Martian moons of Deimos and Phobos. Both moons were now effectively under Frieden control, with sizable Frieden fleets present in the vicinity of both colonies. 
====UNSC Expeditionary Fleet====
The UNSC Expeditionary Fleet, fresh from the successful conclusion of Operation: LEVIATHAN, possessed 21 carriers and 23 cruisers. 
*7 heavy carriers, 5 assault carriers, and 9 light carriers
====Deimos Station====
When Frieden forces occupied Deimos, colonial security forces had not resisted; no UNSC marines were present in the colony, and the small naval detachment responsible for manning patrol craft and tugs had abandoned their equipment as ordered and been evacuated to the only UNSC vessel present near the colony, the 275-meter-long defense ship Drake of Deimos. The old defense ship remained near the colony but was being left alone by Frieden forces for the time being. In addition to station service members, more than a hundred civilians had fled to the relative safety of the defense ship; Drake of Deimos had sufficient life support systems for the evacuees and enough supplies to last until April, but beyond that, options were limited. 
====Phobos Station====
When Freiden forces arrived at and occupied Deimos, colonial administrators on Phobos put extensive contingency plans into action: UNSC garrisons in Fort Roche and Fort Wendell had gone on alert while colonial security fortified Skyresh and conducted an orderly withdrawal from Gulliver City. Opik City, Port Sharpless, and Stickney Industrial were likewise abandoned by security and military personnel alike, with public announcements instructing willing civilians to travel to Skyresh without delay. UNSC patrol craft and miscellaneous auxiliaries were moved to Skyresh and the local defense ship, the 520-meter-long UNSC Sentinel of Phobos, redeployed in the settlement's immediate proximity to defend it aggressively. Frieden forces arrived shortly thereafter and did not challenge local UNSC forces; the fleet was here to fight the Koslovics, not the UEG. Approximately 1,200 UNSC soldiers and 300 marines were present on Phobos with plentiful infantry weapons and limited artillery. 
===UNSC Belt Command===
UNSC Belt Command was thinly spread in December 2163, with far-flung garrisons and extensive convoy commitments. Four carriers were present within Belt Command's domain, but two of them were underway to Jovian Space. Belt Command did possess 11 cruisers, however, and practically every commissioned frigate in the fleet. Approximately 9,400 UNSC soldiers and 1,600 marines were stationed in the belt. 
*1 heavy carrier and 3 light carriers
*3 heavy cruisers and 8 light cruisers
===UNSC Jupiter Sector===
UNSC Jupiter Command encompassed the Jovian moons of Callisto, Europa, Ganymede, and Io, and the extensive colonies established throughout the Jovian Trojan camps. Following the assassination of Nadja Mielke on November 3, open warfare between the Friedens and Koslovics had reignited on all four moons. The UNSA had quietly abandoned the Trojans in mid-November, ceding both camps entirely to the Frieden movement. Nevertheless, the UNSC possessed a strong position on each moon, with approximately two million soldiers under arms in fortified garrisons. Another 7,600 UNSC marines were present in naval installations and aboard UNSC ships. The Jovan fleet included two heavy carriers and eleven cruisers. 
*2 heavy carriers
*3 heavy cruisers and 9 light cruisers
===UNSC Perimeter Forces===
All UNSC assets beyond Jovian Space fell under the authority of the Perimeter Force Command. In December 2163, these limited assets included the ships of the Kuiper Expedition and Saturn Station and the small UEG garrison in Forseti City on Titan. 
*Kuiper Expedition: 1 replenishment ship, 1 research ship, and 1 survey ship
*Saturn Station: 2 survey ships
==Total assets==
The UNSC possessed 10,962 commissioned ships: 
*1,404 warships: 38 carriers, 16 battleships, 118 cruisers, 580 destroyers, 135 frigates, and 517 sloops; 
*5,618 patrol vessels: 10 patrol ships and 5,608 patrol craft; 
*4,554 auxiliary ships: 6 ammunition ships, 356 cargo ships, 10 combat support ships, 4 command ships, 9 communications relay ships, 54 destroyer tenders, 12 hospital ships, 12 mobile dockyards, 27 repair ships, 140 replenishment ships, 4 research ships, 14 salvage ships, 6 survey ships, 4 tracking ships, 6 training ships, 146 transport ships, 3,739 tugboats, and 5 other ships.

===Reserve assets===
While the UNSC would establish and maintain massive stocks of decommissioned spacecraft in years to come, in December 2163 there were no such facilities or plans for creating a reserve fleet. Due to the endless demand for military spacecraft during the Interplanetary War, the UNSC kept all available ships in service as long as possible. The first UNSC ships to enter reserve did so in the months after the conclusion of the fighting in 2170.
