This almost unknown bomber took part in some nocturnal attacks on Berlin. It originated as a derivative of the Stal-7 (Stal-7) transport designed by R.L.Bartini. The Yer-2 was a gull-winged aircraft, with the engines and landing gear nacelles fitted at the crank in the wing; it had twin tailfins.

Around 320 were built.
