Ship Engines and Power Cores

Power Cores

The power core is the most important system on a ship, as it provides power to every other system. The table below lists the ship size each core is designed for, as well as the PCU it provides and its cost. Each Large and smaller ship has room for only a single power core by default, but Medium and Large starships can be fitted with an extra power core housing. Huge starships can have up to two power cores, Gargantuan starships can have up to three, and Colossal starships can have up to four. Some Cores are so large they are the size of smaller ones, labeled as Core Size. If 2+ Warp Cores exist in 1 ship, the highest Warp Capacity is used.
Though some ships are exceptions to this standard, they are rare in design. A power core typically has a backup battery system for use in emergencies that can provide limited power—enough for life support, gravity, and comms, but no other systems—for 2d6 days.

Impulse Engines

Ships rely on conventional impulse engines to move between locations in a system, to explore, and to engage in combat. They are designed for ships of a specific size (specified in the Size column of the table below), and they can’t be installed in a ship of an incorrect size. The maximum speed of a starship’s engines either grants a bonus or imparts a penalty to Piloting checks to fly the vessel, as noted on the table below.
Impule Engines are also used when landing on and taking off from a planet. Large and smaller Starships generally have little difficulty landing on and taking off from a planet with low gravity or standard gravity (unless there are atmospheric conditions such as high winds or storms). The GM determines whether or not a starship’s pilot must attempt a Piloting check to land a starship with a speed lower than 8 on a planet with high gravity, with failure meaning it might crash. Due to their sheer size, Huge and larger starships can’t land on planets, and must use shuttles or other means to ferry crew and goods to a planet and back.
