On August 18, NATO brought together nearly 25 aircraft near Russia’s Kaliningrad autonomous region, including American and Norwegian fighters, an AWACS aircraft, the rare electronic warfare plane EA-37B Comps Call, and Apache attack helicopters.

The flight group flew routes over the northeastern part of Poland, focusing on the electromagnetic environment around Kaliningrad.

NATO presented the operation as a planned exercise for interaction and deterrence, not as a response to any specific action by Russia.

The operation continued in the following days and, before official confirmation, was first identified by open-source intelligence (OSINT) flight trackers.
