“After the completion of tests in the first stage, their results will be implemented on previously released aircraft and on the next series of aircraft,” said a source.
He noted that “the volume of improvements of previously released Su-34 will be relatively small, primarily due to the improvement of the software.”
According to the interlocutor, "the refinement of the aircraft is facilitated by the fact that the onboard radio-electronic equipment has an open architecture."
As for the serial production of a deeply modernized Su-34M aircraft, it will start no earlier than 2020.
“A modernized airborne radar with improved characteristics will be installed on the Su-34M. In addition, the aircraft will be equipped with outboard containers with additional special-purpose equipment. Such containers have already been tested in the air, ”said a source.
Earlier it was reported that in Russia, work is underway to create new air-to-surface and air-to-air guided missiles, which are currently being tested on Su-34.
