The RS-122 is a self-propelled multiple rocket launcher system developed by Georgia in the early 2010s to replace and modernize its fleet of aging Soviet-era BM-21 Grad systems. Designed and manufactured by the State Military Scientific-Technical Center Delta (STC Delta), the RS-122 marked Georgia's first domestically produced artillery rocket system and was part of a broader post-war initiative to improve the survivability, accuracy, and autonomy of its armed forces following the 2008 Russo–Georgian War.

The system is based on a Ukrainian KrAZ-63221 6×6 chassis and is equipped with 40 launch tubes for 122 mm Grad-compatible rockets. It features a fully armored cabin, digital fire control, and GPS-assisted targeting, enabling rapid deployment and operation without exposing the crew. The baseline model, known informally as Magaria, entered service in 2012, and an upgraded variant with expanded crew capacity and improved optics, known as GG-122, was publicly displayed in 2014.

Although conceived with export potential in mind, the RS-122 has not been sold abroad and remains in limited service with the Georgian Defense Forces. It has been used primarily in training and evaluation exercises, and its development is seen as a symbolic and strategic step toward Georgia's goal of defense self-sufficiency.

In the aftermath of the 2008 Russo–Georgian War, the Georgian Armed Forces conducted a broad reassessment of their military capabilities, with particular attention to artillery systems. The war had exposed significant limitations in Georgia’s Soviet-era equipment, including the BM-21 Grad multiple rocket launcher. These systems lacked modern fire control, armored protection for crews, and the mobility needed to survive and respond quickly on a modern battlefield. As Russia fielded more advanced and better-coordinated artillery forces during the conflict, Georgia identified a pressing need to modernize its own systems.

This modernization effort coincided with a strategic shift toward domestic defense production. The Georgian government prioritized military self-reliance, partly to reduce dependence on foreign suppliers and especially to avoid vulnerabilities tied to Russian-manufactured hardware. In 2010, the State Military Scientific-Technical Center Delta (STC Delta), a state-owned defense enterprise under Georgia's Ministry of Defense, was tasked with developing a modern multiple rocket launcher system that would retain compatibility with the widely used 122 mm Grad rockets while addressing the survivability and targeting deficiencies of legacy systems.

The resulting design, later designated RS-122, was conceived as a next-generation platform incorporating improved crew protection, digital fire control, and enhanced battlefield mobility. The system was mounted on the Ukrainian KrAZ-63221 6×6 truck chassis, selected for its proven durability and off-road performance, as well as for its availability through non-Russian supply channels. The RS-122 also reflected broader international trends in post-Soviet artillery modernization, drawing informal influence from Poland’s WR-40 Langusta and other NATO-compatible Grad upgrades.

Although designed with an eye toward potential export markets, the RS-122 primarily served as a demonstration of Georgia's emerging domestic defense manufacturing capabilities. It marked a departure from complete reliance on Soviet-era systems and was promoted as a symbol of technological independence within Georgia's broader military modernization strategy.

The RS‑122 program began in 2011 when Georgia's State Military Scientific‑Technical Center Delta (STC Delta) initiated development of a new Grad‑compatible multiple rocket launcher system. The primary aim was to address shortcomings revealed during the 2008 Russo–Georgian War, particularly outdated Soviet equipment that lacked modern targeting, protection, and mobility.
