Rocket boosters, also called rocket thrusters, were twin devices that allowed R2 series astromech droids to fly through the air. The famous droid R2-D2 was equipped with such boosters, and he put them to good use throughout the Clone Wars. However, by the time of the Galactic Civil War, R2-D2's boosters had not worked in ages, and his warranty was long expired. During the Age of the Empire, the C1-series astromech droid Chopper also had a set of rocket boosters.
