Mammalian Fleet

A ship is a spaceborne vessel controlled by an empire. They are the primary way of interacting with objects and entities in the galaxy via specific ship orders. Ships are classified into civilian and military vessels, the former being controlled individually while the latter form fleets. All ships must be constructed and repaired at Starbases where there is a Shipyard module. Each Shipyard module can construct one ship at a time.


Civilian shipsEdit

Civilian ships represent all unarmed vessels of an empire and are controlled individually. They are equipped with shields, armor and core components automatically once the next tier component tech is unlocked at a free cost and do not have to return to a Starbase to receive component upgrades. Each civilian ship, excluding transports and construction ships, has a monthly maintenance cost of 1   Energy, and each construction ship has a maintenance cost of 0.75   Energy.

Civilian ships have the evasive fleet stance by default meaning that they will attempt to escape the system whenever a hostile fleet enters it.

Construction shipEdit

Construction ships are used to build every space structure. They are not used up during construction meaning that they can go on to do other tasks after they have finished their building project. Fleet Orders allow the construction ship to build the following:

Build order Cost Maintenance Description
  Outpost   depends on Government
  75 per hyperlane from closest owned system
  1 Energy The Starbase is a space station used to claim star systems and expand your borders. It can only be built in orbit around a star. The full cost is dependent on which star system is being claimed.
  Mining Station   100 Minerals   1 Energy Mining Stations are used to collect Minerals, Energy Credits and Strategic Resources from uninhabited planets, stars and asteroids. Mining Stations that collect Energy do not cost any upkeep.
  Research Station   100 Minerals   1 Energy Research Stations are used to collect Physics, Society and Engineering research data from uninhabited planets, stars and asteroids.
  Observation Post   100 Minerals   1 Energy Observation Posts can be built in orbit around planets inhabited by primitive civilizations to study their society.
  Megastructure Site   depends on Megastructure
  depends on Megastructure
  5 Energy Megastructures are truly massive construction projects only possible in the zero-g environment of space.

Science shipEdit

See also: Surveying

Science Ships are the primary method of exploring the galaxy and the stars and systems within it. They require a scientist to operate.

Once crewed, the Science ship can conduct a survey of individual objects within a system. During these surveys, it can discover resources present on a celestial body (i.e.: planets, stars, asteroids, etc.). A survey may also result in the discovery of an anomaly. Furthermore, an object needs to be surveyed only once and any future hidden resources (such as strategic resources) will be automatically revealed once the requisite technology is researched. The Science ship can also survey debris left after a space battle which may yield research points or possibly even unlock unique technology options.

Science ships can also assist the research of a planet. Upon activation, the science ship will orbit the planet and boost its research output depending on the skill level of the scientist on board.

Colony shipEdit

See also: Colonization

The large colony ships allow an empire to settle habitable planets. When ordering the construction of a colony ship, the player is given the option of choosing the species of the pop that is to be sent to the new colony, inheriting all of its traits and ethics. Pops are not consumed nor transported in this process. Once finished, the colony ship may be sent to any habitable world within range to start a colony. Colony ships take one year to build and their upkeep cost is maintained throughout the whole colonization process. Alternatively, colony ships can also be built through the interface of the planet to be colonized.

The cost of a colony ship in an organic empire depends on the government and the empire's dominant species archetype.

Primary species          
  •   200 Alloys
  •   200 Food
  •   200 Consumer Goods
  •   200 Alloys
  •   500 Food
  •   50 Alloys
  •   1000 Food
  •   200 Alloys
  •   200 Minerals
  •   200 Consumer Goods
  •   200 Alloys
  •   500 Minerals
  •   50 Alloys
  •   500 Minerals
  •   500 Food

The cost of a colony ship in a   Mechanical or   Machine Intelligence Empire is always   400 Alloys regardless of the government.

Empires with the   Corporate Dominion or   Private Prospectors civics can also construct Private Colony Ships, which cost 500   Energy instead.

Empires with the   Calamitous Birth origin can also construct Lithoid Meteorites, which cost 500   Minerals instead.

Transport shipEdit

See also: Land warfare

Transport ships are where assault armies are kept. After an army has been recruited it is automatically embarked in a transport ship which will be orbiting the planet where they were created. Therefore, they cannot be built manually. While armies have an upkeep cost, transport ships cost no additional   energy to maintain. After a battle transport ships will heal the embarked armies.

During war transport ships must be carefully escorted by a military fleet since they are unarmed. Their only purpose is to carry assault armies into enemy planets so that they can occupy them. Additionally, some special projects require a transport ship to be completed.

Military shipsEdit

Military ships represent all armed vessels of an empire and unlike civilian ships they can be grouped together into fleets and led by an Admiral. Military ships require both   Energy and   Alloys as monthly maintenance. They are designed via the ship designer.

Military ships are classified by their hull size, which influences their combat stats, cost, available sections and components and Command Point cost. Each ship takes twice as much time to be built compared to the previous one in the category. There are four hull sizes available, plus the Titan and Colossus with the   Apocalypse expansion, and the Juggernaut with the   Federations expansion. Each ship size has two technologies that increase its hull points and (up to battleships) one technology that decreases its build cost and increases its build speed.

Upgrading shipsEdit

Military ships must be upgraded manually when an upgraded design is created. The cost for upgrading each ship is simply the difference in construction cost between the new design and the old one. Each ship upgrades individually, with multiple ships being upgraded simultaneously if the starbase contains multiple shipyards.

When upgrading a ship, the system will attempt to use the most recent version of the same class name. If no design of the same class name is available, then the upgrade process will retrofit them to the most-recently saved design of the same size instead.

If a ship obtained via an event contains components not yet researched the ship should not be allowed to upgrade. Upgrading it will replace the components with the latest researched ones, even if those are inferior.

Naval CapacityEdit

Naval capacity represents the number of military ships that an empire can manage. Going beyond this limit will increase ship maintenance costs by a percentage equal to the overcame value. For example if an empire exceeded its naval capacity by 50% it will increase the maintenance cost of each ship by 50%. Each empire can build a Titan for each 200 Naval Capacity, up to a maximum of 20 Titans at 3800 naval capacity. An empire's base naval capacity is 20, and is modified by:

  •   Galactic Force Projection ascension perk adds +80
  •   Each Soldier Job adds +4
  •   Each Warrior Drone Job adds +4
  •   Each Duelist Job adds +2
  •   Each Starbase Anchorage module adds +4, or +6 with the Naval Logistics Office building
  • Each naval doctrine technology adds +30
  •   Each Fleet Management Procedures repeatable technology adds +20 (can only be researched 5 times)
  • Each Pirate Free Haven corporate building adds +10
  • Each Mercenary Liaison Office corporate building adds +10
  • Each Strategic Coordination Center level adds +50
  •   Citizen Service civic increases Naval Capacity by +15%
  •   Subspace Ephapse civic increases Naval Capacity by +15%
  •   Naval Contractors civic increases Naval Capacity by +15%
  •     Genocidal civics increase Naval Capacity by +33%
  •   Fleet Logistics Corps / Automated Underway Replenishment supremacy tradition increases Naval Capacity by +20%
  •   Master's Teachings: Warring States edict increases Naval Capacity by +10%
  •   Grand Fleet unity ambition increases Naval Capacity by +20%
  •   Fleet Organizer ruler trait increases Naval Capacity by +15%
  •   Brain Slug Host ruler trait increases Naval Capacity by +10%
  •   Covenant: End of the Cycle increases Naval Capacity by +100%
  •   Federation member empires can have reduced Naval Capacity by -10%/-20%/-30% to be set aside for use by the Federation fleet, depending on Fleet Contribution law.
  •   Satrapy empires have reduced Naval Capacity by -30%

Maximum Naval Capacity may never exceed 9999. This is not a hard cap on the number of ships an empire can support; it is fully possible to exceed this limit as long as an empire can afford the increased maintenance fees for all of its ships. In fact, the AI will frequently build over its naval capacity if it has the resources to maintain its fleets. Because of this, it may likewise be necessary for a player to build over naval capacity, especially when preparing to go to war against an AI with equivalent or better fleet power.

Command LimitEdit

Command Limit is a limit on how large any one individual fleet in an empire can be. An empire's base command limit is 20, increased by the following (the hardcoded maximum is 500 but cannot be reached without mods):

  • +10 per hull type technology
  • +20 per fleet doctrine technology
  • +10 per Admiralty Support Staff technology (repeatable, but only 5 times)
  • +10   Distinguished Admiralty civic
  • +20   War Games \ Three-Dimensional Awareness \ Combat Variable Mitigation supremacy tradition
  • +20   Galactic Force Projection ascension perk

Maximum attainable Command Limit without mods: 260

Outliner format: <current command usage>/<fleet command limit> (<template's planned usage>)

Ship RankEdit

As ships partake in battle they will increase their rank. Ships, when built, start off with zero experience. Ships get +1 experience every day they are in combat and +0.1 experience every day they are suppressing piracy.

Ranks are classified as follows:

Rank Exp Points   Damage   Hull Points   Evasion
Regular 0-99 0 0 0
Experienced 100-999 +10% 0 0
Veteran 1000-9999 +20% +5% +5%
Elite 10000 +40% +10% +10%

Ship starting experience can be increased by the following factors.

Factor Effect
  Fleet Supremacy edict +100
  Martial Alliance federation +100
  Built from a Starbase with a Fleet Academy building +100
  Built from a Mega Shipyard +100

Colossal shipsEdit

Colossal ships are the largest ships that can be built. There are two classes of colossal ships, the Colossus and the Juggernaut. Each require the starbase to have the   Colossal Assembly Yards building before they can be constructed, and each can only be constructed once. They can be reconstructed when they are destroyed. Colossal ships cannot be merged with regular fleets.


Real scale of a humanoid juggernaut compared to a titan

The Juggernaut is a colossal ship which can construct, repair and upgrade ships the same way a Starbase can. It has 10 times the hull points of a Titan and feature six   Hangar slots and two turreted   Extra Large slots. It also has its own set of aura components, which are significantly more powerful than the Titan's own. In addition to the empire limit of one, federation fleets can support a single Juggernaut.

Juggernauts have two shipyards and can build, repair or upgrade up to two ships at a time. It cannot build Titans or Colossi but it can upgrade or repair them. The Juggernaut can also upgrade itself and will automatically start repairing itself after a battle. It cannot be repaired or upgraded at a starbase. Juggernauts can retreat and go Missing in Action to reappear at the nearest friendly starbase like all regular fleets. Fleets can set a Juggernaut as their homebase.

Fallen Empires cannot build Juggernauts.


Humanoid empire using a World Cracker

The Colossus is a colossal ship that has a single weapon slot which can be equipped with a weapon of mass destruction capable of affecting an entire planet. The technology required to build them can be accessed by taking the   Colossus Project ascension perk. Each Fallen Empire has a 10% chance to get a Colossus at start and they can build as well after they Awakened.

Colossi are unable to attack enemy fleets, as they lack the weaponry to do so. During space battles a Colossus will follow direct orders and will maneuver straight to its designated target. This means that the Colossus will do things such as going straight through an ongoing space battle to fire upon an enemy planet, unless its stance is set to Evasive.

An Empire that owns a Colossus gains the ability to declare Total Wars on other Empires. Similarly, any Empire can declare Total Wars on the Colossus owner. During a Total War, any systems captured by either side will be immediately annexed and the war can only end in the total destruction of either side or a status quo.

  • If a Colossus is destroyed during a Total War, nothing happens. The war is still a Total War.
  • If a Colossus is built during a regular war, nothing happens and the Colossus can be used as normal. If one side is totally destroyed by the Colossus, the war ends and the war goal is not enforced. The same is true if an Empire that owns a Colossus is dragged into a regular war, usually because of   Federation or   Defensive Pact.

Using a Colossus causes large amounts of War Exhaustion on the targeted empire, and gives it +50% Ethics Attraction towards   Militarist and   Xenophobe, which can cause the diplomatic and political climate in the region to grow even more hostile over time.

The   Colossus Project ascension perk does not directly unlock the Colossus hull or its weapons; rather, the perk grants access to an associated special project which, once finished, will unlock both the ship and its weapon. After the special project is halfway completed the empire will be prompted to choose a starting Colossus weapon. The empire can later research other types of Colossus weapons and retrofit it into their Colossus via the ship designer.

A Colossus can carry the following weapons, which can only target planets, ringworlds and habitats:
