The Integrated Electronic Warfare System (IEWS) is an electronic warfare special weapon introduced in Ace Combat 7: Skies Unknown. It is exclusively available on the ADFX-01 Morgan. When activated, the IEWS simultaneously provides Electronic Countermeasure and Electronic Support Measure to the player and their allies in the immediate area. The former makes it more difficult for enemies to lock on, and causes enemy missiles to suffer a large decrease in homing. The latter makes it easier to lock on to enemies, and friendly missiles gain a large boost in homing.
