According to RIA Novosti, the reason for the re-equipment of the Su-34 was that the bombers attack in the near area and are potentially vulnerable to the effects of Ukrainian electronic warfare. The new equipment “effectively counters enemy electronic warfare.”
The Su-34 fighter-bomber was commissioned in 2014 and took an active part in the operation against international terrorists in Syria.
The aircraft is armed with a GSh-30-1 30mm cannon and the latest modification of R-27 air-to-air missiles with a launch range increased to 130 kilometers. The Su-34 is also equipped with the most advanced air-to-surface munitions, including powerful anti-ship missiles.
The combination of the Khibiny electronic countermeasure complex with the SAP-14 and SAP-518 active jamming stations provides reliable protection against air defense. Su-34s can reportedly disappear from enemy radar screens.
