Jamming isn’t eavesdropping. It also isn’t getting radar and other data on the position of enemy air and ground forces. The IL-22M hasn’t flown over Ukraine, and neither have equivalent NATO planes like the E-8 JSTARS or E-3 AWACS flown over Ukraine, Belarus, or Russia. The reason the Wagner group was able to shoot an IL-22M down is because it was within range of their surface to air missiles in Russian airspace.
