Thruster

Thrusters are the primary source of propulsion for starship cruising.
Thrusters add speed and acceleration in the direction that they are pointing; therefore, applying thrust to one or multiple sides of a ship is possible.
A thruster's exhaust path may not be blocked by any block of the active starship at any distance, with the exception of one glass or glass pane block with no space in between.

Afterburner Thruster

Afterburner
An afterburner thruster, with a magma block for the glow block.
Properties
Acceleration	3.0
Speed	17.5
Weight	5.0

Afterburners provide plenty of acceleration and speed in a small package but are less efficient than other thrusters.

Ion Thruster

Ion
An ion thruster, with a sea lantern for the glow block.
Properties
Acceleration	0.05
Speed	4.0
Weight	1.0

Ion thrusters accelerate very slowly but can be used to achieve high top speeds.

Plasma Thruster

Plasma
A plasma thruster, with a redstone lamp for the glow block.
Properties
Acceleration	0.75
Speed	2.5
Weight	1.0

Plasma thrusters have a lower top speed but provide efficient acceleration.
