Typically, ships have attachment points to attach components, weapons, missiles, and accessories. These items can be purchased new from many ship manufacturers or specialty builders; or second hand at waste pickers.
Avionics is the on-board electronics allowing to control the elements of the ship and to collect their state.
The propulsion systems include all the elements which take part in the propulsion of the ship apart from the thrusters themselves.
The thrusters allow the ship to evolve in its environment. A spacecraft has a very large quantity of them, in order to perform maneuvers in space and in the atmosphere of a planet, in all situations.
Systems have a direct impact on the functioning of the ship. They protect it, regulate it, and provide it with energy.
Ship components are defined by three major criteria: Size and Grade and Class.
|Size||The size is a classification assigned to every component slot of a ship, only components of matching sizes can be installed|
