Ultimate development of the SB line, intended as dive-bomber.
In 1939 it became obvious that speed of the SB series has to be increased. Previous attempt - the MMN failed to satisfy all requirements, but was re-engined, equipped with new VISh-22E propeller. Radiators moved inside the wing with intakes on the leading edge - and aircraft became the SB-RK.
Still it was not enough, and instead of pushing more modification SB-RK was given new role - dive bomber. Results were good, and aircraft was in production (1940- 1941) until superior Pe-2 replaced it.
Last attempt to keep SB series flying was the SB-B , but it did not enter production.
~200 built under designation Ar-2 (with single machinegun in the nose).
