In total, over the six story arcs, there are seven factions that appear. Some are the result of mergers, and others are the result of breakaways. While I am far from finishing, I will be posting as I type. Here you will find everything about each faction, from general historical background to weapon preferences. Reunified Earthen Dominion (R.E.N.)
(Cynthia-class Destroyer after a kill)
The Reunified Earthen Navy is the dominant military force in the Solar System, as well as Alpha Centauri and Delta Aristotle. REN warships are perhaps the heaviest, as well as the most defensible ships ever known to man. The coveted and rare Neptunian alloys used as armor and frames add such integrity to the ship’s structure that any REN ship is a force to be reckoned with, even if slightly armed. However, due to their heavy weight, they are not the most nimble and agile of fighters, and are more inclined to rely on heavier ships to do most of the work.
The Reunified Earthen Navy was created around 300 years after the Fall to deal with the increasing ferocity and frequency of LSK pirate raids, and was the result of UWA military leaders mass-defecting to the rebel cause after realizing the futility of fighting a two-front war against pirates and rebels. The Navy hierarchy was strictly adhered to, with the top admirals looked up to almost as gods, whose orders were to be obeyed without question.
Initial fleets were comprised of old UWA warships, which initially succeeded in defending Mars, but the outdated maneuvers and protocols later proved impossible in stopping LSK mass-attacks and the ruins of Earth fell to pirates. With the ever-increasing industrial power of Mars, Venus, and 3rd Sector space stations, and the gradual decline of the hierarchal order, it was decided to allow captains to customize their ships at their own expense, greatly improving the efficiencies of each ship. However, this led to the rise “illegal” modifications, as tampering with engines and other vital components for power was not simply dangerous for the ship, but for the entire fleet.
Ship schematics for the REN show that Neptunian armor is their primary means of defense, which contributes to nearly 45% of the ship’s net weight. Weaponry, due to advanced technology capable of creating chemical-based explosions even in a vacuum, is usually projectile-area based.
Ship engines are prototype-assembled thrust reactors that run on solid hydrogen. Because of the volatility of the fuel, engines are not to be tampered with under any circumstances.
Kinetic Cannon (NK-500): Capable of shooting projectiles weighing over 500 tonnes. Primarily, cannons usually use "Enke" nuclear warheads to achieve maximum performance.
MAW (Magnetic Acceleration Weapon): Found on heavier ships in the Earthen Navy, these heavy weapons work by using super-magnets to accelerate Neptunian bolts at very high speeds. One well-placed shot is capable of completely severing a ship in two.
Turbine Cannon: Modification of an engine to utilize its rotational kinetic energy to hurl bits of white-hot fuel rods at the enemy. Capable of decimating small ships with a few hits. This is usually found on civilian transports, as the Navy normally forbids such modifications to the engines.
Kinetic Cannon (C-III): Identical in concept, similar in design, the smaller counterparts are designed to fire faster, and reload faster, at the disadvantage of having a smaller (but no less dangerous) payload.
Torpedo: Homing missile. Useful for tracking down irksome harassers.
Swarm-Rockets: Used on Interceptors, Cruisers, and Battleships. Interceptors use it to devastate targets in strafe runs; the sheer number of missiles makes defending against such assaults very difficult. Battleships and Cruisers utilize a slightly different version designed to shoot down strafing interceptors.
Flak: Used on frigates and destroyers to disable incoming missiles projectiles.
O2-Charge Rockets: Found on destroyers and cruisers. Rockets consist of a small Oxide charge that may detonate prematurely, but is generally successful in disabling missiles and projectiles.
A-2K Rifle: The standard weapon for light infantry units issued in 2000 AF. Weapon is fairly accurate even at 250 meters. Utilizes 5cm Neptunian-cased bolts.
A-2K-A Rifle: Automatic variation of the A-2K. Compromises range and accuracy for higher rate of fire. Utilizes 3cm carbon munitions. Standard weapon for heavy infantry units.
A-2K-Sniper Rifle: High-powered rifle used by professional sniper units. Capable of penetrating 2.5 cm non-Neptunian armor at 3000 meters. Utilizes 7.5 cm Neptunian bolts.
V-Pistol: Small handgun issued to non-combat personnel. Highly lethal at close range. Utilizes C-shatter rounds.
SL-RPG-2: Shoulder-mounted rocket launcher. Launches two anti-tank rockets.
SL-RPG-4: Variant of the SL-RPG-2. Launches 4 Heat-seeker missiles. Used primarily against air units.
