Standardized starship ratio : Most Human space going crafts have the same dimensional ratio, where the width and the height are 1/10th of the length, giving them the vague appearance of a oversized rocket covered in guns and armor. Thus, unless otherwise stated, all crafts will follow these dimensions.
European Federation Star Navy :
Glimmer-class light cruiser :
Length : 300m.
Tonnage : 270 000 m3.
Armament type : Missile based, with kinetic weapons point defence and counter-missile launchers.
The Glimmer class is old. Very old. In fact, original plans for it predate the European Federation itself, and were originally made by the European Space Defence Agency for the European Union. The first ship of the class was put in service in 2063, and the class itself continue serving until 2138, making it the longest serving warship class in the known universe beside the Hudson class cruiser. The ship was well known for being positively minuscule compared to more modern light cruisers, barely qualifying as a large frigate in fact. It was originally armed with a grand total of 16 missile launchers and 38 point defence guns, although thankfully the class was upgraded to use 18 missile launchers, 6 light railguns, and a total of 51 point defence gauss turrets, preventing it from becoming totally obsolete. The Glimmer was only deployed in direct fleet to fleet combat during the interplanetary wars, where it performed admirably, before being retired to a purely patrol and anti-piracy role in the early 2100s. This was mostly due to the announcement of the existence of hyperspace, and the decision not to equip the ageing Glimmers with hyperdrives.
Eternity-class light cruiser :
Length : 600m.
Tonnage : 2 160 000 m3.
Armament type : Missile based, with energy weapons point defence.
The Eternity class is a reliable, advanced (although not cutting edge) light cruiser class originally introduced in response to the Alpha Centauri accident. Although the EFSN has stopped laying down more of them, as new constructions are focusing on the new Infinity class light cruisers, there were still 16 Eternity class in various states of construction and armament when Alexandra was precipitated into hyperspace.
Infinity-class light cruiser :
Length : 800m.
Tonnage : 5 120 000 m3.
Armament type : Missile/Energy weapons hybrid, with energy weapons point defence grid.
The Infinity class is the cutting edge in terms of light cruisers. Specifically built to accompany and protect Dawnstar-class battleships, as well as to be able to fight an entire UIS frigate squadron on it's own, these ships are one of the finest warship class in known space. At the time of Alexandra's disappearance, only the leading ship of the class, the EFSN Infinity, was in service, with 3 more undergoing armament, and 18 in various states of construction.
Starfire-class battleship :
Length : 3.3 km.
Tonnage : 359 370 000 m3.
Armament type : (Mk1) Missile based, with energy weapons point defence. (Mk4) Token missile and long range energy weapons, massive energy weapons point defence array.
The Starfire class is an older, but still reliable, battleship class originally built to project the EFSN's power into the outer system and reliably guard the colonies around Jupiter and Saturn. This class is quite probably the single most produced battleship class for the EFSN, at around 36 put into commission, and 6 that were scrapped before completion to make room for the Dawnstar class. The class went through several iterations, where every ship was gradually upgraded to the new iteration through refits, named Mk1 through 4. Mk1 was the original run of the class. Mk2 was a series of upgrade to it's systems and especially the installation of gravitational engines, allowing reliable long duration solar system wide deployments. Mk3 constituted the passage to a hyperspace capable warship through the installation of a hyperdrive. The Mk4 is a massive refit from a mostly missile based warship to a point defence and escort ship for the much heavier and better armed Dawnstar class.
Nova-class battleship :
Length : 3.6 km.
Tonnage : 466 560 000 m3.
Armament type : Energy weapons based, with energy weapons point defence.
The Nova class is one of the ships introduced to the EFSN in response to the UISN's new generation of dreadnought. Made above all else to be able to survive into a drawn out slugging match with the UISN's new warships, the Nova-class sacrifices a degree of firepower and acceleration for insane redundancy and several times the armor of a normal battleship.
Dawnstar-class super-battleship :
Length : 6.8 km.
Tonnage : 3 144 320 000 m3 or 3.144 km3.
Armament type : Missile/Energy weapons hybrid, with energy weapons point defence.
The Dawnstar class is the largest space going warship class ever put into service, let alone one with hyperspace capability. It is a last generation warship of the European Federation, representing the cutting edge of it's technological and industrial might. In total, 6 Dawnstar class were ordered, although on the day that Alexandra was precipitated into hyperspace, only 3 had been fully commissioned, 2 were still being armed, and a single one was still in construction in the EFSN Aurore star yards.

United Interstellar States Navy :
Ottawa-class light cruiser :
Length : 400m
Tonnage : 640 000 m3
Armament type : Railgun based (short range kinetic weapons), minimal kinetic point defence capabilities.
The Ottawa class is one of the strange semi-modern ships of the UIS. The class' design is fairly old (it was first introduced in the 2130s), but it remains an impressive weapons platform. Particularly, the Ottawa class was always meant as an anti-piracy patrol ship (since most pirates cannot afford missiles) and a short range anti-corvette ship when in larger fleets. While it had steadily fallen into obsolescence, the resurgence of short range, direct fire weapons engagements with the EFSN's new generation of warship has brought the Ottawa class back into the spotlight. In fact, the UISS Quebec (an Ottawa class) is the only ship to date to have managed to destroy a Nova class battleship, by somehow managing to score a direct hit on the Scarlet Nova's primary reactor and causing it to suffer a catastrophic containment breach, destroying the entire ship.
Enterprise-class Super-Carrier :
Length : 4.8 km.
Tonnage : 1 105 920 000 m3 or 1.105 km3.
Armament type : Fighter based, with kinetic/energy weapons point defence capabilities.
The Enterprise class is a testament to the UIS' military industrial complex perseverance in it's failures. Despite the Alpha Centauri campaign thoroughly proving spaceborne carriers to be obsolete against long range energy point defence weapons, the IUS' massive military corporations managed to pass through the necessary bills to produce an even bigger class of carriers. Fortunately, the Winter Takeover took place before the class could enter mass production. In the end, of the planned 48 Enterprises, only 8 were constructed. On the day of Alexandra's disappearance, only 6 remained in service, two having been destroyed by the EFSN Dawnstar and Northstar respectively at the 3rd battle of Alpha Centauri. They serve as auxiliary capital ships to the IUS' dreadnoughts, dispatching fighters and drones for force recon purposes. While their combat effectiveness is undeniably pathetic for their tonnage, their contribution to the reconnaissance and situational awareness capabilities of a UIS taskforce is significant.
Colorado-class Dreadnought :
Length : 4.6 km.
Tonnage : 973 360 000 m3.
Armament Type : Missile based, with kinetic point defence capabilities.
The Colorado class is a textbook example of the UISN's doctrine. It is designed for medium range missile engagements and sustained combat, with massive missile and point defence capabilities. It is also a reflection of the UISN's technological constraints. The UIS is, after all, significantly behind the EF in terms of fusion reactor and hyperdrive technology. This not only limits it's ability to produce viable energy weapons armed starships, but also to ship ammunition to Alpha Centauri through hyperspace. Thus, instead of the extremely long range of the EFSN's missiles, the IUS had to go for shorter ranged, but smaller, missiles. The Colorado class is also an example of the fact that the UIS never saw the massive increase in energy weapons range and acceleration of the EFSN Dawnstar class coming, as the Colorado class was uncompromisingly designed for keeping the range open and pumelling it's target with missiles. It is thus not the ideal ship to have in a short range energy weapons engagement, which explains the initial EFSN victories at Alpha Centauri.
Everwinter-class dreadnought.
Length : 5.6 km.
Tonnage : 1 756 160 000 m3 or 1.756 km3.
Armament type : Railgun based with secondary missile batteries, medium kinetic point defence capability.
The Everwinter class dreadnought is a post-winter takeover UIS warship, and is now the primary wall-of-battle ship of the UISN. Built after Ciel took over the UIS, these warships are the UISN's answer to the Dawnstar. Although smaller, lighter, and less efficient than the Dawnstar-class super-battleships, the Everwinter-class has managed to hold their own against even these leviathans through sheer toughness, reliability, and numbers. In particular they have become famous for their sheer refusal to die, being able to duke it out in furious close range engagements with entire battlegroups, and leave shattered wrecks behind while still being functional. The Everwinter class are the bane of the EFSN, and a sign of things to come.
In total, 18 Everwinters have been built by the UIS, and 12 more were being built or armed when Alexandra disappeared.
Indian-Oceanian Commonwealth Navy :
Sydney-class heavy cruiser :
Length : 1.2 km.
Tonnage : 17 280 000 m3.
Armament Type : Railgun/Missile hybrid, kinetic point defence capabilities.
The Sydney class is...average. There is nothing really special about this ship class. It is an excellent anti-piracy ship, and a decent fleet escort or squadron ship. It will serve well in virtually any role in a pinch. It is, for all intents and purposes, a jack of all trades, which was precisely what the IOCN was aiming for. Overall, it is one of the most produced heavy cruisers (the most produced one being, of course, the Hudson class heavy cruiser of the UISN and MRN), and a common sight in Sol, especially near Earth or the asteroid belt.
New Dehli-class battleship :
Length : 3 km.
Tonnage : 270 000 000 m3.
Armament type : Missile based, kinetic/plasma point defence capabilities.
The New Dehli class is the solid, reliable back upon which the IOCN is built upon. Despite it's smaller size than many modern capital ships, it remains a mighty warship, and it's newly invented plasma point defence turrets are pointing towards a new shift in doctrine and technology for the IOCN. Overall, it is an excellent, if light, capital ship, capable of putting up a decent fight even against technologically superior opponents like the EFSN or UISN.
Martian Republican Navy :
Hudson-class heavy cruiser :
Length : 1.1 km
Tonnage : 13 310 000
Armament type : Missile based, kinetic point defence capabilities, Anti Missile Missile (AMM) capability.
The Hudson class is incredibly old. In fact, at the time Alexandra was precipitated into hyperspace, it was over a century old. Built in the 2050s to serve as the mightiest spaceborne warships ever built, these ships served as the backbone of the UIS' expansion throughout the solar system. However, the class became infamous for the Martian Revolt, when Mars overthrew the UIS rule over the planet, and declared independence. The Hudsons were extremely short legged in terms of reaction mass at the time (as they were still equipped with fusion drives, due to the newly invented -and expensive- grav drives being reserved for new constructions), and most of the ships of the class had been stationed on Phobos, Mars' largest moon, because of it's refuelling depot and refit yards. During the Martian Revolt, 80% of the Hudsons were taken over by the newly created MRN, with over 2/3rd of them due to their crews rebelling. The rest were either crippled in the ensuing battle or were scuttled by their commanders to avoid capture. In the UIS, they are known as the "Red Betrayers".
Olympus Mons-class Superfortress :
Dimensions : 15x7.5x4.5 km
Tonnage : 506 250 000 000 m3, or 506.250 km3
Armament type : Missile based, with extremely high railgun and kinetic point defence capability.
The Olympus Mons class is one of the largest man made objects in known space. At 506 gigatons, it outmasses most navies. However, it is worth noting that the Olympus Mons' armaments and armor are actually a fraction of what it's tonnage suggest. In truth, while it isn't quite an asteroid with guns on it, most of Olympus Mons class' mass is made up of unprocessed nickel iron covered in a layer of steel. Proper starship armor is only put on or near critical systems and weapons emplacements. Still, it is a most impressive weapon of war, capable of taking on an entire fleet on it's own. Only 3 Olympus Mons (Olympus Mons, Arsia Mons and Ascraeus Mons) were ever built (and for good reason, given the staggering cost of each of them), and all three orbit Mars at equidistant intervals, together being capable of covering any attempt to approach the planet. This, however, prevents them from protecting one another. The UIS' threat assessment teams concluded that the Olympus Mons superfortresses were indeed impressive, but nowhere near the invincible behemoths they are supposed to be. In this, they are quite right, despite the impressive numbers, in truth the Olympus Mons class could easily be neutralized in any short range energy weapons engagement with a capital ship group, and it's relatively hard to manoeuver nature makes it vulnerable to a sustained kinetic bombardment, if the attacker was willing to risk the collateral damage involved.
