South Korea AF 65-329 E-7 Wedgetail AEW&C (Airborne Early Warning and Control) they call it 'Peace Eye' over western SoKo

Eventually these will replace the E-3 AWACS and the AF has orders for them but it will be several years before that happens: Australia, Turkey currently use these with the RAF-UK scheduled to start in 2024

USAF to replace E-3 Sentry aircraft with Boeing’s E-7 Wedgetail

The Boeing 737 Airborne Early Warning and Control (AEW&C) airframe, known as the E-7, is an air battlespace management platform, capable of detecting airborne threats including hostile aircraft and cruise missiles. Four countries operate the E-7: the Australian air force was the first to purchase the system, and has designated it the E-7A Wedgetail; the South Korean air force operates it under the name “Peace Eye”; the Turkish air force designates their four E-7s as the E-7T Peace Eagle, and the United Kingdom’s Royal Air Force operates it as the Wedgetail AEW1.

The E-7 consists of a Boeing 737-700 airframe, with the addition of a Northrop-Grumman produced Multi-Role Electronically Scanned Array (MESA) radar. This radar, which is fixed unlike the rotating radome of the E-3 Sentry (AWACS), has 360 degree capability with a 200+ nautical mile range in all weather conditions. The Australian air force deployed its Wedgetails to the Middle East for Operation Okra in support of the coalition fight against ISIS.
