The Sukhoi Su-8 ( Russian Сухой Су-8 ) was a Soviet attack and dive fighter aircraft from the time of World War II and in this capacity one of the largest in the world. In favor of the Ilyushin Il-10 , it did not go into series production.

development

The development work began in 1942 in the OKB of Pawel Sukhoi under the project name DDBSch ( Russian ДДБШ, Двухмоторный Двухместный Бронированный Штурмовик , twin-engine, twin-engine, double-engined, two-engine, two-engine , bronze-engined battle aircraft tower. The model was executed in composite construction, fuselage and wings consisted of a duralumin frame with plywood cladding. The important parts (cabin, engines, tanks and coolers) were, as is usual with many attack aircraft, heavily protected. In total, the armor weighed 1680 kg.

In 1943, two prototypes were made, which were tested in 1944. The Su-8 performed well, but in the end the decision was made for the Il-10, as the retraining of the pilots from the Il-2 to the Il-10 would be easier due to the similarity of the two types and no major incisions would have to be done when converting production.
