History
The Bolkhovitinov "OKB" (disign bureau) was formed in 1937 and was responsible for producing several
a/c types mostly experimental. The project "S" (dubbed "Spartak") was conceived in 1936.
The prototype was ready at the end of 1937 and in summer of the next year the initial flight trials began.
Despite of very promising tandem engines layout, the plane turned out to be sluggish and underpowered
because of considerable loss of power in the transmission gear and wrong wing profile.
Although the wing was modified, the plane's characteristics were still poor and the whole project
was abandoned in 1941.
