The R6-series astromech droid represented the sixth astromech droid design produced by Industrial Automaton within their R-series line of droids; it followed previous models.
The R6 was launched shortly following the Battle of Endor, and it was Industrial Automaton's attempt to restore their image following the significant failure of their R5 series. To demonstrate that subsequent series would not be inferior to their famous R2-series, the R6's designers dedicated considerable time to resolving every issue and flaw that affected the preceding model. After a multi-year planning phase, IA released the R6 model, clearly aiming to regain consumer confidence.
The R6 series shared numerous characteristics with the older, yet still favored R2 series, highlighting Industrial Automaton's engineering focus. Initially, IA intended to release a military model exclusively for FreiTek's E-wing escort starfighter. However, given the years required for the E-wing project's completion, IA saw an opportunity to reconnect with civilian customers. With a successful design and eager buyers, IA ensured the R6's marketability by pricing the shelf models attractively. While more expensive than the R5 and R4-series, which had less ambitious objectives, it was less costly than the R2 series upon its original release.
Before Grand Admiral Thrawn initiated his campaign to reclaim the galaxy for the Galactic Empire, the R6 was reportedly "selling like QuickSnacks." While R2-series astromech droid achieved higher sales figures, the R6 remained a profitable model, competitive in sales with its predecessor.
Although the head's conical-frustum shape resembled that of the R5 (potentially causing initial concern among consumers) rather than the classic dome, the similarities ended there. The R6 possessed the same versatile programming and array of gadgets reminiscent of the experienced R2 units, but featured updated key systems, including its sensor package and processor. The standard R6 could store 12 hyperspace jump coordinates within its astrogation buffer and included many tools and compartments lacking in earlier models not designed for extensive space travel. While the R6 offered minimal innovation, it fulfilled the unmet demand of loyal Industrial Automaton customers.
