Ship reactor

Ship reactor

Powers a ship on its journey between stars. Takeoff requires a long powerup process that is likely to attract raiders.

A ship reactor is a ship part needed to take off. Activating the reactor causes 15 days of raids but must be done to launch, creating the primary challenge of the Ship launch ending.

Acquisition

Ship reactors require the Starship reactor research project to be completed in order to be constructed. Each requires Steel 350 Steel, Plasteel 280 Plasteel, Uranium 70 Uranium, Advanced component 8 Advanced components, 65,000 ticks (18.06 mins) of work, and a Construction skill of 8.

Ship reactors cannot be built under a roof (though a roof can be constructed afterwards).

Summary

A ship reactor must be activated in order to launch a ship. The activation process takes 15 days, during which the colony will be attacked by many raids. The raids will stop once the reactor is fully activated. There does not need to be a completed ship in order to start activation; you can start as soon as the reactor is built.

Otherwise, a ship reactor will provide 1000 W of power at all times, regardless of activation.

Analysis

It's best to activate a reactor before building the rest of the ship. Doing more construction will increase your colony's wealth, increasing the strength of raids. This also gives you more flexibility in defending the reactor, as you can surround it with walls, making it a non-target for most raiders. After the raids are done you can build the rest of the ship at your leisure.

Power

As a power source, its cost and size make it extremely inefficient, even in the endgame.

In the extreme endgame, where you have an infinite amount of resources from deep drills or long-range mineral scanners, then ship reactors provide eternal, "free" power without space restrictions or any amount of colonist work. If you're just trying to launch a ship, then there's no reason not to build a reactor whenever possible, and link it to your main power supply.
