The aircraft was assigned the military designation B-228 (later changed to Il-2B) and the nose code BA-11. Subsequently it was converted to the electronic reconnaissance version, designated Il-28RTR. Coded BA-51 it served with the 47th reconnaissance air regiment till it was decommissioned in September 1969 and transferred to the museum."
