X4: Foundations Windows game

screenshot: this is typical Interceptor class fighter: very low hull, but extremely fast, with amazing boost ability. This ship is designed to recon, or to fight using hit-and-run tactics. It is very hard to hit, due to speed.

Small size ships - S size

• Fighters

• very cheap to construct, fragile, agile compared to other ships, usually use S size weapons, but there are special models constructed specially for handling M size weapon pods.

• • Code: F/I, Interceptor - smallest, low hull, very fast and agile, dangerous only in swarms, ideal recon ship, or light sniper
• • Code F/M, Multirole - this type has been designed to carry more missiles than other fighters, it is bit less agile than Interceptor
• • Code F/A, Assault - this is heaviest type of fighter, designed to survive hard battle conditions and carry on mission, attack larger vessels. Strong hull, less missiles. Sometimes have capacity to use M size weapons.
  • Code F/B, Bomber - slowest, least agile of fighters family. Bombers have amazing missile or torpedo storage, and in squadrons firing barrage can be deadly to even large capital vessels. Despite thick hull, their low speed and low agility makes them almost defenseless against turrets and anti-fighters batteries, and thus rarely operate without other fighter's escort. Some bombers are also being used as small military transport, often called just taxi.
• Utility vessels: gas & mineral miners

screenshot: F/A - QUADCORE Assault Fighter - one of the best fighters, enormous firepower of 4 M sized weapons places this fighters among most dangerous predators.

screenshot: another example of F/A Assault Fighter. This model is able to carry M sized shield, making it look more like turtle than a fighter. Despite weird look, Parasite is an excellent fighter, able to compete for the name of the king of small size vessels. ~It can engage larger vessels for a longer time, before being forced to retreat to re-charge shields.

screenshot: M size vessel, GS Gunship Mutagen-class. It is more fragile than almost 3-4 times larger destroyers, but it carries comparable weaponry. Very, very dangerous vessels, able to take down capital vessels alone, in swarms they are almost unstopable. Mutagen class is the only able to carry 2 L size weapon pods, in addition to multiple M and S sized pods. It also carries many turrets.

Medium size ships - M size

• Gunships, Gunboats

• These medium size vessels are around 3-4 times bigger than fighters, and usually same smaller than destroyers. Usually they carry decent amount of missiles/torpedos, can carry multirole missions from recon to assault. They are often used as anti-fighter vessels, but heaviest models, like Mutagen engage even capital vessels. Often used as escort for cruisers, or destroyers.
• CODE: GS - Gunship, GB - Gunboat [GS is a heavier version, better weaponized]
  
  

• Space Uboots

• These medium sized vessels are usually slightly less armored than other military ships of their size. They are designed to hit with missile barrage and run away, they cannot withstand serious close combat fight for a long time. They carry a lot missiles, and have many torpedo-only weapon slots. Uboots are very dangerous when they are well stocked, but without their precious ammo, missiles and torpedo present minor danger.
• CODE: SU - Space Uboot
  
  

• Destroyers

• Largest medium size vessels, carry heaviest weapons, able to carry all kinds of missions, with close-combat against capital vessels. Human destroyer of Victory class is able to use L size engine, and can achieve amazing speed, while alien's Ronin class destroyer can carry L size turret. Mutant's version of Spore-class, can carry many drones and has powerful primary weapons battery.
• Not as well armored as L sized cruisers, destroyers can still take a lot of damage, but they are a lot more agile and usually faster.
• CODE: DD - Destroyer
  
  

• Utility

• other ships, medium sized transports, mineral and gas miners

screenshot: heavy cruiser, Spore-class. Very well armed and armored with 8 main weapon pods and 13 turret groups can still achieve amazing speed, when supplied with re-engineered Xenon engines. Like all capital vessels it requires a lot more advanced technology than small and medium sized spacecrafts.

Large size ships - L size

• Cruisers

• Large size ships are significantly harder to construct, need more advanced technology and more resources. But they offer splendor of capital-class vessels: destructive assault firepower of primary weapon batteries, and murderous barrage of side turrets of all sizes and calibers.
  
  
• • Code: CL - Light Cruiser - their hull has weak armor, to maximize missile storage capacity. They are more agile then other ships of their size, but usually play support role, and attack from safe distance.

• • Code CA - Heavy Cruiser - this type has reinforced hull, and thick armor. They base their firepower on guns, not missile batteries. They are respected for their reliability, can withstand heavy enemy fire for a long time. Single cruiser is able to take down whole space station if it is left without defense within minutes.
  • Code BC - Battlecruiser - almost as powerful as a battleship - it has comparable firepower, but it is less armored. They conduct high risk missions, often engage capital vessels, but usually have highest casualties rate among capital vessels. Their armor protects them from some large turrets bombardment for a short time, and if caught by surprise, can be damaged or destroyed even by a smaller vessel.

screenshot: SS Werewolf with full weapon panel. 3 Large main weapons, medium pods, and 2 small. It has also 32 turrets divided into 14 groups. It has impressive missile/torpedo storage, although smaller than Nautilus-class. It is hull however, compared to other cruisers, is 2-4 times less resistant to damage.

• Space Ships a.k.a. Space Submarines

• Officially categorized as cruisers, Space ships, or space submarines are very unique vessels, designed to conduct secret operations behind enemy lines, or to disrupt enemy logistic chain.
• Currently there are only two types:

• • Code: SS Space ship - NAUTILUS class, is heavier, less agile, but better armored. Has more turrets, primary batteries, and can carry unbelievable amounts of missiles and torpedos. It is excellent deep space operations vessel, able to conduct operations for months without need to resupply. It is often been escorted by it smaller version:

• • Code SS - Spaceship - WEREWOLF class - this type has lighter hull, but it is weaponized almost as good as Nautilus-class. It is however more agile, and faster, which can make it even more dangerous in close combat encounters. It can easily evade slow, high damage particles for heaviest guns, but certainly its shields can withstand high-speed lasers for limited time. That's why Werewolves captains often use hit-and-run tactics, barraging victim with salvo of torpedos and heavy weapons, then runaway to a safer distance.

• Utility

• other ships, large sized transports, mineral and gas miners

Extra Large size ships - XL size

• Engineering Vessels

• Extra large size ships commonly named Builders. They command drones, that build stations. They are huge vessels, with heavy hull, but usually very lightly weaponized, thus defenseless against military ships.

• • Code: EV - Engineering Vessel
    

• Auxiliary (Battle)ships

• Extra large size vessels. They constantly work on resupplying fleet with missiles, torpedos, they even repair smaller vessels. Thanks to their extra large storage they can support large fleets or conduct transport operations, for instance mutant's Glucose-class auxiliary with its 2 billion m storage is considered to be largest transport vessel in known universe.

• • Code: AUX - Auxiliary ship - common auxiliary vessel

• • Code: BB-AUX Auxiliary Battleship - aliens, Shogunate of Shimizq and Kayama Corporation designed special version of battleship which can also play a role of an auxiliary ship. This Battleship of Lord Saginaki class is a most powerful vessel any alien faction can create.
• • BB LORD SAGINAKI class vessel, has multiple L size weapon batteries, and considerable amounts of M size as well. But it's main firepower is provided by 18 large turrets batteries (groups of turrets), and couple m sized. This places this battleship among most destructive vessels ever created, comparable only to mutants' pride: BB-CV Biomutant

• Carrier Vessels

• Extra Large size capital class ships commonly named carriers. They play a role of a mobile space base for smaller vessels. They can re-equip and repair smaller units, if provided with needed resources. They provide shelter in their hangars, and considerable protection from enemy fire. Some carriers specialize in drone transport, while other host full sized vessels with living crew like fighters or even destroyers.

• • Code: CV - Carrier Vessel - usually carriers rely on fighters escort, and are not heavily armed. To keep as most vessel carriage capacity as possible, they are stripped of heavy armor, and naturally still quite resistant to heavy damage, they are not match compared to a battleship.

• • Code BB-CV Biomutant - mutants designed unique combination of carrier vessel and battleship. Design is very crude, and ship looks more like a turret platform than advanced military battle vessel. But it does its job better than brilliant, it has two engine groups, mounted away, and it is very hard to stop, or even slow down. It is also possibly fastest XL vessel in space, due to engine amount.
  • CODE SHDC King Biomutant - unique version of mutant's carrier vessel, it can carry unbelievable 400 drones on board. It has also best armored hull, known in the universe, that is second only to Xenon I-class battleship.
