The plane, delivered two months ahead of schedule to a military base in Gimhae, was the second 737 to have been modified to the AEW&C configuration by Boeing's South Korean partner, Korea Aerospace Industries.
"A key factor in our continuing success in delivering Peace Eye's powerful capability is the close working relationship that exists among the Boeing team, the ROKAF, the Defense Acquisition Program Administration, and our Korean and U.S. industry partners," said Randy Price, Boeing Peace Eye program manager.
Based on Boeing's 737-700 commercial airplane, the 737 AEW&C aircraft provides battle-management capability, using multi-role electronically scanned radar and crew consoles that track airborne and maritime targets simultaneously.
The Peace Eye program for South Korea includes four aircraft as well as ground support systems for crew training, mission support and maintenance.
Boeing said Australia is already operating five Peace Eye AEW&C aircraft and Turkey will soon receive its first.
