Another way to transliterate the name is Er-2.

The Yermolayev Yer-2 was a bomber aircraft which took part in some nocturnal attacks on Berlin. It originated as a derivative of the Stal-7 ("Steel-7") transport designed by 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.
