Spaceships

Ship designing

All the covert machinations on Earth and industrialization efforts in space are the path for factions to build fleets of ships to protect and advance their interests. Once the factions unlock the early-game orbital shipbuilding tech, and the follow-on space dock project for their habs, they can build interplanetary spacecraft.

With the right modules, ships can prospect and found habitats, but the primary role for most ships is combat.

At any time, you can design ships out of the modules you've developed. Once you have a shipyard, you can build the ships themselves out of your space resources and, if necessary, boost and money.

Individual ships are constructed at habs at a space dock, shipyard, or spaceworks module. Ships may be built out of a mix of resources mined in space and material boosted from Earth. When construction is complete, ships are deployed docked at the hab that built them.

To save a ship design, it must have a drive, power plant, radiators, battery, armor materials (even with zero thickness), at least one propellant tank, and an assigned role. Specialty designs like colony ships must also have a utility module that allows them to perform the role's function.

Ship Performance

Ships have the following characteristics that need to be tracked:

• Wet Mass: Wet Mass is the total mass of the ship when fully loaded with fuel. Mass influences the ship's maneuverability. Higher mass decreases Delta-V and turn rate. Hovering over it shows a breakdown with the origin of all Wet Mass.
• Crew: How many personnel will serve aboard the ship.
• Cruise Acceleration: How quickly the ship can change its velocity in the strategy layer. Higher cruise accelerations allow ships to overcome a space body's gravity and take more direct trajectories to its destination.
• Combat Acceleration: How quickly the ship can change its velocity in the combat layer. Some drives are capable of short periods of higher acceleration in combat situations.
• Turn Rate: How quickly the ship can change its orientation in combat. This value is dependent on the length and mass of the ship; shorter ships will turn faster all things being equal.
• Heat Sink Capacity: Heat sinks serve as a temporary substitute for a ship's heat management while a its vulnerable radiators are retracted in combat. Higher values allow the ship to fight longer without extending its radiators.
• Battery Capacity: The ship's batteries store power from its power plant for use by most weapon systems when the power plant is unavailable. More advanced batteries are able to recharge during combat.
• Construction Cost: Resources required to build the ship. Boost and Money can be substituted for any resource that is lacking. This may increase build time as materials are delivered from Earth.
• Construction Time: How long it will take to build the ship once all required materials are at the shipyard. Larger shipyards reduce build time.
• Support: The monthly cost of supporting the ship. If support costs go unpaid the ship will be more vulnerable to other faction's attempts to seize the ship.
• Cruise Delta-V Determines where the ship can go and how fast it can get there. More propellant increases Delta-V. More mass on the ship decreases it.
  • Ships with less than 8 kps Delta-V may have trouble reaching the Moon from an Earth orbit.
  • Ships with less than 30 kps Delta-V will not be able to reliably perform interplanetary transfers from Earth.
  • Ships with roughly 60 kps will be able to perform more extreme transfers such as transfering from Mercury to Saturn.

Hull

Designing a ship begins with selecting a hull. The type of hull determines the number of nose and hull weapon hard points, the number of utility modules, and the length of the hull.

Shorter ships will have a lower moment of inertia, meaning they will rotate faster than their longer counterparts.

Role

Each ship has a role, which informs the game on whether the ship is a combatant or noncombatant, what range it should engage in during combat and how much propellant will it want. The role affects the autodesigner behavior and where the ship is placed in a combat formation.

• Ships with Long strategic range will emphasize propellant for interplanetary operations
• Ships with Short strategic range will limit propellant mass in favor of maneuverability

Ship Components

Power Plant

A ship's power plant provides energy to both the ship's drive and other ship systems. The mass of the power plant scales with the greater of the power requirement of the drive or the ship's systems. The power plant also produces waste heat that must be stored in heat sinks or expelled by radiators.

Note: Many drives require a certain class of power plant to function, and in some cases, a lower-tech power plant of the correct class may not be able to produce enough power to support an advanced drive.

Drive

Drives expel propellant from the tail of the ship to make the ship go places. Drives come in a variety of forms, but are rated by two common values: thrust and exhaust velocity. High-thrust drives can achieve higher velocities more quickly, and high-exhaust velocity drives use less propellant to do so. Together these values determine the power required by the ship's power plant. Adding 100-ton propellant tanks to the ship increases the ship's Delta-V, or how much it can change its speed.

Note: Many drives require a certain class of power plant to function, and in some cases, a lower-tech power plant of the correct class may not be able to produce enough power to support an advanced drive.

*Rounded

Propellant

Each ship must have one or more 100-ton propellant tanks. The number of propellant tanks determines the ship's Delta-V value. There is no hard limit to the number that can be placed on a ship. However, each tank of propellant adds mass to the ship, which reduces its acceleration and gives diminishing returns for delta-V. The resources used to make propellant is determined by the drive.

Radiator

Radiators remove waste heat produced by the ship's power plant. They scale in mass based on the power plant's output and efficiency. Because these are highly vulnerable in combat, they can be retracted if the ship has heat sinks in one or more utility slots. However, once the ship's heat sink fills up, the radiators must be extended again to protect the lives of the crew.

Radiator	Combat Vulnerability When Deployed	Waste Heat (tons/GW)
Aluminum Fin	Very High	400
Titanium Array	High	181.8
Molybdenum Pipe	Moderate	222.2
Nanotube Filament	Moderate	153.8
Ionic Dust	Very Low	333.3
Cobalt Dust	Very Low	200
Tin Droplet	Very Low	125
Alien Exotic Spike	Low	83.3

Battery

The ship's primary battery stores energy from the power plant and provides it to weapons, life support, and other key systems when the main power plant is unable to do so, either due to damage or when the drive is operating on ships that don't have an independently powered drive. High-power weapons can drain the battery quickly in combat. Improved batteries will have a larger capacity or a faster recharge rate. You may add additional batteries of the same type in utility module slots for greater capacity.

Battery	Mass (tons)	Capacity (GJ)	Time to full charge (minutes)

Graphene	120	48	32
Quantum	80	80	27
Superconducting Coil	2	40	9
Exotic Nanowire	10	60	10

Armor

Armor plating on the ship will absorb incoming weapons fire, preventing damage to internal components. Each point of armor will absorb 20 Megajoules of energy at a single location on the hull before vaporizing. Different armor types require a different thickness and mass to absorb a particular amount of much damage. Note that a point of lateral armor is much more massive than nose and tail armor because it had a greater surface area to cover.

Utility Modules

Utility Modules perform a variety of functions to widen a spacecraft's capabilities. Extra batteries may also be put in utility module slots.

Weapons

Weapons systems are either mounted on the ship's nose or on the hull. Nose weapons are typically more powerful than hull weapons of a similar size, but they have a limited field of fire. Hull weapons can fire in any direction around the ship. Weapons also come in various sizes; larger weapon systems are generally more powerful but will take up multiple weapon slots.

Certain weapons may only be used offensively against enemy ships and hab modules; others may only be used defensively to shoot down incoming projectiles and missiles, and still others can be used against both types of targets. Weapons can have up to four different possible fire modes:

• Focus Fire: Will fire at primary target only.
• Attack: Will fire at primary target if it is in range, otherwise will attack the nearest available target.
• Guardian: Will fire at incoming projectiles and missiles before targeting enemy ships.
• Defense: Will fire at incoming projectiles and missiles; will not target ships.

All weapons have a cooldown, and some weapons fire in salvos. If a weapon does not have a salvo listed, it will fire once every time the cooldown timer is up. For example, the Light Railgun Battery Mk1 has a cooldown of 30s and does not have a salvo listed; once in range, it will fire one shot every 30 seconds. If a weapon has a salvo listed of X shots / Y s, it will fire one shot every Y seconds X number of times, and then will go on cooldown, after which it will fire another salvo. For example, the Krait Missile Bay has a salvo of 2 shots / 5 s and a cooldown of 60 seconds; once in range, it will fire one shot, wait 5 seconds, fire a second shot, and then will go on cooldown for 60 seconds.

Weapons can be classified in certain general types:

• Guns: Use magazines, high ammo capacity. Cannot bombard. Low damage. Short range. Cheap.
• Missiles: Use magazines, low ammo capacity. Limited bombard. High damage. Will chase the target. Only available as hull weapons.
• Magnetic Weapons: Use magazines, high ammo capacity. Use energy. Can bombard.
• Plasma Weapons: Use energy. Cannot bombard. High damage. Only available in large sizes.

Refits

Factions may refit ships at habs with ship construction modules. Refitting is generally limited to replacing parts of a similar type.

• Hull cannot change.
• Power Plant can change, if the new Power Plant is of the same Class.
• Drives can add or remove thrusters to current drive, or substitute a drive with the same Classification, required Power Plant, and Reaction Product.
• Weapons can change if the new weapon is of the same Class and Mount. (so 1-hull laser can only be replaced by 1-hull lasers).

Reddit user CrimsonLionDC has created a spreadsheet which includes all ship components with detailed specifications such as drive efficiency, cooling type and technology prerequisites. https://www.reddit.com/r/TerraInvicta/comments/y32akq/updated_ship_drives_chart_with_all_ship_parts_and/

Elouda has created a chart of all the engines in game. The X-axis of the chart shows exhaust velocity of the drive. In TI this directly translates to the efficiency or range of the ship. Engines with high EV have more dV all things being equal. Y axis shows the thrust, this is how fast the ship can accelerate. This is especially important in battle but very low thrust engines take very long time to transit as well. For example, real life ion drive has very high efficiency, meaning it can go far for the same fuel but at the same time the thrust is tiny so accelerating takes days or weeks. https://steamcommunity.com/sharedfiles/filedetails/?id=2868559848
