L3Harris has begun converting two Bombardier business jets into Airborne Early Warning and Control (AEW&C) aircraft for South Korea. The work is part of a $1 billion contract awarded to the US firm in September 2025, with four Global Express 6500 jets to be converted in total. L3Harris will integrate mission systems, including an Active Electronically Scanned Array (AESA) radar system from IAI-Elta. The company has experience in similar projects, having worked on the US Air Force’s EA-37 Compass Call electronic warfare aircraft and Australia’s MC-55A Peregrine platform.
