The Sukhoi Su-6 ( Russian Сухой Су-6 ) developed by the Experimental Design Bureau (OKB) Sukhoi was a Soviet attack aircraft from the time of the Second World War . It was executed parallel to the Il-2 , but did not go into series production in favor of this.


After evaluating the experience with the SchB attack aircraft prototype of the Su-2 , the conception began in 1940 and a year later the first SA model was completed, which was still designed as a single-seater. As the example of the Il-2 had shown in the meantime that single-seat attack aircraft were very vulnerable to enemy fighters, the redesign to a two-seat S2A with rear-facing gunner's seat took place in 1942 . Although the performance of this type exceeded that of the Il-2M-3 with the exception of the bomb load, the Su-6 did not go into series production because of the Il-2 production that had already started. In this extremely difficult phase of the Second World War, the Soviet Union could not afford any production losses due to a production changeover, and the armor protection of the Il-2 was rated as better. In 1943 a prototype with the in-line engine AM-42 with 2000 HP developed by Alexander Mikulin was tested, but was also not put into series production.
