Boeing said it completed the integration of major subsystems aboard a 737 airborne early warning and control (AEW&C) aircraft for Australia’s Project Wedgetail. The subsystems include communications, navigation, mission computing, radar and electronic warfare self protection. Boeing said it conducted tests aboard the aircraft and at its System Integration Lab in Kent, Wash. Boeing said integration is a major step toward functional checkout of the AEW&C system with the aircraft at the end of April. FAA certification and qualification testing are scheduled for this summer. Boeing will deliver the first two of six Wedgetail aircraft to Australia in March 2009, and the remaining four aircraft by mid-2009. Turkey and the Republic of Korea also have purchased four 737 AEW&C aircraft each. The aircraft is equipped with Northrop Grumman's Multi-role Electronically Scanned Array antenna with integrated identification friend or foe capabilities. The system also includes a flexible, open architecture for cost-effective future upgrades, an extensive communications suite and aerial refueling capability.
