The R4-P Astromech represented a specific model within the R-series of astromech droid units, produced by Industrial Automaton. Functioning as an R4 astromech droid, this particular model was designed for permanent installation within the specially modified Jedi variant of the Delta-7 Aethersprite-class light interceptor from Kuat Systems Engineering. This integration enabled the starfighter to connect with KSE's Syliure-31 hyperspace docking ring.
Obi-Wan Kenobi, a Jedi Master, was often accompanied by R4-P17, a droid belonging to this precise R4-P Astromech model.
Interestingly, although designated with the R4 prefix, the R4-P model exhibited a dome-shaped head, a feature typically found in standard R2- or R3-series astromech droid units, rather than the cone-shaped head characteristic of typical R4 droids.
