The Sukhoi Su-12 was an experimental twin-engine aircraft developed by the Sukhoi Design Bureau in the immediate aftermath of World War II. Conceived as a specialized platform for reconnaissance and artillery spotting, the Su-12 was intended to provide a faster, jet-powered alternative to the slower piston-engined aircraft traditionally used for battlefield observation and fire correction.
Design work on the Su-12 began in 1945, led by Pavel Osipovich Sukhoi. The aircraft was part of a broader wave of early jet projects from the Sukhoi OKB, which included the Su-10 jet bomber and early fighter prototypes such as the Su-9, Su-11, Su-15, and Su-17. As a twin-jet design, the Su-12 utilized turbojet engines to achieve the speeds necessary for modern reconnaissance roles. While the aircraft underwent testing and evaluation and was eventually recommended for production, it never entered series production. Only a small number of prototypes were constructed, though the exact quantity remains undocumented in available records.
The Su-12's development occurred during a period of significant organizational volatility for its manufacturer. The Sukhoi Design Bureau, which had been established in 1939, was disbanded in November 1949 under the Stalinist administration, with Pavel Sukhoi being reassigned as a Deputy Chief Designer at the Tupolev OKB. The bureau was not re-formed until approximately 1953, after which it produced a new generation of jet aircraft, including the Su-7. Consequently, the Su-12 serves as a technological bridge between the bureau's wartime piston-engined designs and its later successful jet fighters.
Despite its promise, the Su-12 never saw operational service. It was tested under the Soviet Air Forces' evaluation system but did not participate in any combat conflicts. Because it remained an experimental prototype, no operational variants were developed, and no airframes are known to have survived into the modern era. Today, the Su-12 is historically significant as one of the first Soviet attempts to apply jet propulsion to the specialized role of artillery observation.
