Terra Invicta Ship Building Guide

This article serves as a comprehensive reference guide for ship design in Terra Invicta.

The core philosophy of ship design in this game is specialization over generalization. A ship designed to do everything (combat, colonization, and long-range travel) will be heavy, expensive, and fail at all three tasks.

Design every hull with a single, specific mission in mind.

1. Core Concepts: The Stats That Matter

Before selecting parts, understand the two critical trade-offs in propulsion:

• Thrust (Combat Acceleration): Think "Horsepower." High thrust allows a ship to catch enemies in combat and dodge incoming fire. It is essential for warships.
• Exhaust Velocity / Delta-V (Range/Efficiency): Think "Gas Mileage." High EV means the engine uses very little fuel to travel vast distances. It is essential for colony ships and interplanetary travel.

The Goal: Early game drives forced you to choose one. Late game drives (Fusion) offer both.

2. Phase 1: Early Game (Survival Mode)

Scope: Earth and Mars Orbit.

Goal: Defend against the initial Alien Destroyers and Assault Carriers. Don't go broke doing it.

In this phase, you lack the reactor technology to power energy weapons effectively. You must rely on munitions that supply their own power.

The Archetype: The Missile Monitor Swarm

This is a "glass cannon" designed for one thing: dumping a massive "Alpha Strike" of torpedoes to overwhelm alien point defense in Low Earth Orbit.

| Slot | Recommendation | Reasoning |
| Hull | Monitor (Tier 2) | The smallest hull capable of carrying enough missile racks to overwhelm alien PD. |
| Drive | Advanced Pulsar | The only early drive with enough Thrust to catch alien ships in combat. Backup: Pegasus Drive. |
| Reactor | Solid Core Fission III | Missiles need almost no power. Use the cheapest, simplest reactor available. Weight is acceptable here. |
| Weapons | 4x Missile Racks | Use Artemis Torpedoes (early game) or Copperheads. Fill every slot. |
| Radiator | Tin Droplet | Very heavy, but very rugged. In the early game, you want radiators that don't snap off when hit by a stray laser. |
| Heatsink | Lithium (Small) | Missiles generate no heat. You only need a small sink to absorb engine heat during short combat maneuvers. |
| Armor | Nose: 10+, Side/Tail: 2 | Aliens usually shoot the front. Put almost all armor on the nose. Use basic Composite armor. |

3. Phase 2: Mid Game (Expansion & Skirmishing)

Scope: Inner Solar System out to Jupiter.

Goal: Establish a presence on Ceres/Jupiter and hunt down isolated Alien stations.

You now have better reactors, allowing the transition from pure missiles to mixed kinetic/energy weapons.

Archetype A: The Brawler (Destroyer/Cruiser)

A sustained combat vessel meant to fight longer battles than the missile monitor.

| Slot | Recommendation | Reasoning |
| Hull | Destroyer or Cruiser | Need more internal slots for utility modules and better armor capacity. |
| Drive | Firestar Drive (Gas Core) | The best mid-game balance of thrust for combat and efficiency for Jupiter runs. |
| Reactor | Gas Core Fission | A massive upgrade over Solid Core. Lighter and more powerful, enabling energy weapons. |
| Nose Weapon | Heavy Coilgun (Kinetic) | The main damage dealer. Coils punch through alien armor better than early lasers. |
| Hull Weapon | Green Arc Lasers | Essential for Point Defense (shooting down alien missiles/plasma). |
| Radiator | Tin Droplet | Still the king of reliability until better materials are researched. |
| Heatsink | Exotic or Lithium | Energy weapons generate heat. You need a larger capacity sink now. |

Archetype B: The Colony Ship (Utility)

A non-combat ship designed to cheaply carry a "Colony Module" to Mercury, Ceres, or Jupiter.

| Slot | Recommendation | Reasoning |
| Hull | Escort | Small and cheap. |
| Drive | Grid Drive | Extremely high Exhaust Velocity (Mileage). It has terrible thrust, but can cross the solar system on a cup of fuel. |
| Reactor | Solid/Gas Core | Warning: Electric drives like the Grid Drive consume reactor power to move. Ensure the reactor is big enough to feed the engine. |
| Utility | Colony Module | The entire purpose of the ship. |
| Weapons | None | Do not waste mass on weapons. If it gets caught, it dies. |

4. Phase 3: Late Game (Total War)

Scope: Entire Solar System to the Kuiper Belt.

Goal: Destroy Alien Motherships and assault their main bases.

Fusion technology changes everything. You no longer have to compromise between thrust and range. Ships become incredibly fast, heavily armored, and mount devastating energy weapons.

The Archetype: The Fusion Dreadnought/Titan

The apex predator. These ships are designed to fight fleets of 20+ alien vessels and win.

| Slot | Recommendation | Reasoning |
| Hull | Dreadnought or Titan | Maximum weapon slots and armor capability. |
| Drive | Zeta Helion or Daedalus Torch | The holy grails of propulsion. Massive thrust AND massive efficiency. |
| Reactor | Inertial/Magnetic Confinement Fusion | Required to power late-game drives and thirsty plasma weapons. |
| Main Weapon | Plasma Cannon (Large) | The ultimate weapon. Plasma ignores alien point defense and chips away armor reliably. |
| Support Weapon | UV Phaser/Laser | The best point defense and anti-small-ship weapon. |
| Radiator | Adamantane or Exotic | Extremely light and extremely tough. The best of both worlds. |
| Heatsink | Exotic (Max Size) | Plasma and Phasers generate immense heat. You need the biggest battery available. |
| Armor | Adamantane | The best weight-to-protection ratio in the game. Layer it thickly (Nose: 50+). |

5. Universal Component Rules (Reference Guide)

If you are ever unsure what to pick, follow these general rules of thumb:

Reactors (Power Source)

Match the reactor to the weapon loadout.

• Missiles/Kinetics: Low power draw. Use heavy, cheap reactors (Solid Core).
• Lasers/Plasma: High power draw. Use light, high-density reactors (Gas Core, Fusion).

Radiators (Cooling)

Balance ruggedness vs. weight.

• Early/Mid Game: Tin Droplet. It is heavy, but it won't break in the first 10 seconds of combat. Avoid fragile graphite radiators on warships.
• Late Game: Adamantane. Light and tough.

Heatsinks (Heat Battery)

Match to heat generation.

• Missile Ships: Smallest possible heatsink (Standard/Lithium).
• Energy Weapon Ships: Largest possible heatsink (Exotic). You need to fight with radiators retracted, running entirely on the heatsink.

Armor

• Always prioritize Nose Armor. In 90% of battles, your ship faces the enemy directly. A ratio of 5:1 or 10:1 (Nose vs. Side) is standard.
• Upgrade materials as you unlock them: Composite -> Carbon Nanotube -> Adamantane.
