"And what's this, a Mark II reactor drone? Haven't used these clunkers in twenty years!"
―Owen Lars mistakes R1-G4 for a Mark II reactor drone[src]

The Mark II reactor drone was a model of utility droid manufactured by Industrial Automaton whose body shell was reused for the R1-series astromech droid.


A model of utility droid, the Mark II reactor drone was built and programmed for menial labor[2] in the engine rooms of large starships.[5] Featuring a tall,[6] black body shell,[1] its heavily shielded outer casing protected its sensitive internal circuitry[2] from harsh external conditions,[7] including the most intensive radiation.[8] However, it also gave the droid a lumbering, cumbersome appearance.[2] The Mark II reactor drone was equipped with a magfield sensor ball.[4]


The R1-series astromech droid reused the Mark II reactor drone's shell

A successful series manufactured by Industrial Automaton,[1] the Mark II reactor drone's body shell was reused for their R1-series astromech droid,[9] also known as the R1 reactor drone,[10] when legal hassles prevented the company from directly transforming their P2-series astromech droid into a consumer product.[9] As a result, R1 units were commonly mistaken for Mark II reactor drones.[6]

Beyond repair, a Mark II reactor drone was cannibalized for its magfield sensor ball by Jawa scavengers on the planet Tatooine.[5] In the year 0 BBY,[11] Owen Lars mistook[12] R1-G4[13] for a Mark II reactor drone, having discontinued their use on his moisture farm twenty years prior.[12]

Behind the scenes[]

The Mark II reactor drone was first mentioned in NPR's 1981 Star Wars Legends radio dramatization of Star Wars: Episode IV A New Hope.[12]
