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 [[Research#{{P|Required Research}}|{{P|Required Research}}]] research project to be completed in order to be constructed. Each requires {{Required Resources}}, {{Ticks|{{P|Work To Make}}}} of work, and a [[{{P|Skill 1}}]] skill of {{P|Skill 1 Level}}.

== 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 [[Raider#Raid strength|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 makes it extremely inefficient, even in the endgame. 
*[[Geothermal generators]]s are cheaper ({{icon small|steel}} 340 [[steel]], {{Icon small|component}} 8 [[component]]s) and provide 3500 W of constant power. Geothermal vents are finite, but a 1-2 generators can power an entire colony for large portions of the game.
*A [[chemfuel generator]] ({{icon small|steel}} 100 [[steel]], {{Icon small|component}} 3 [[component]]s) provides a constant 1000 W for 4.5 [[chemuel]] per day ({{icon small|silver}} 621 market value per year), and only occupies a 2x2 region.
*A [[battery]] plus two [[solar generator]]s ({{icon small|steel}} 270 [[steel]], {{Icon small|component}} 8 [[component]]s) can provide an estimated 1100 W all day (barring some [[event]]s) at roughly 15% the cost.

In the ''extreme'' endgame, where you have an infinite amount of resources from [[deep drill]]s or [[long-range mineral scanner]]s, 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 to your main power supply.
