The Bolkhovitinov S Sparka was Soviet twin-engine light bomber that first flew on 29 January 1940. The two engines were placed in tandem, with each driving a propeller mounted on the nose. The first prototype was only fitted with one engine and had ski undercarriage. It was only intended to evaluate the airframe. The second prototype had both of the planned Klimov M-103 engines fitted.
