4 SU-57s were sent to Syria to test their Byelka AESA Radar, L402 Himalayas electronic countermeasures, 101KS Atoll electro-optical system. The SU-57s were escorted by SU-30SMs and SU-35s. View attachment 6028
The SU-57 was sent to see to test it's radar so most likely against HTS in Idlib. since we lost an SU-25 in Idlib (FSA shot it down) we have been increasing airstrikes in that area. and they might even be used in Eastern Ghouta.
