Boeing Co. and Korea Aerospace Industries Ltd. (KAI) have signed a memorandum of agreement for the Republic of Korea’s E-X 737 airborne early warning and control (AEW&C) program, the parties announced June 19. Boeing signed a $1.59 billion contract with South Korea in 2006 to provide four AEW&C systems along with ground support segments for flight and mission crew training, mission support, and aircraft and system modification support.

KAI will modify, test and deliver three AEW&C aircraft, while Boeing will modify a fourth AEW&C aircraft at one of its manufacturing facilities. Boeing will deliver the first aircraft in 2011 and the remaining three in 2012.
