R2-A6 is an astromech droid in the Star Wars universe. Like other R2-series units, it serves as a skilled starfighter repair and navigation droid, helping maintain ships and support pilots during missions. The designation suggests a standard model rather than a person with a traditional given and family name, so its identifier is used as the full name. R2-A6 appears as a background droid character, contributing to the setting’s lived-in, mechanical world and the broader Rebel or Republic support network.
