The Q7-series astromech droid represented a specific type of astromech droid. This particular model was designed with a spherical dome, a feature reminiscent of the R2 and R4-P series. Its primary function was to serve as a co-pilot on the Alpha-3 Nimbus-class V-wing starfighter, where it also provided assistance with maintaining the craft during flight and ensuring accurate navigation. This assistance allowed pilots to operate with greater safety when navigating near obstructions. During the Clone Wars, the Galactic Republic Navy utilized Q7 astromech droids on their V-wing starfighters.
