北部边缘-2009 联合演习中，诺斯罗普·格鲁门公司的 BAC 1-11 试验机准备起飞测试AN/APG-81有源电子扫描阵列雷达，北部边缘演习营造了世界上最大最复杂的机载电子战环境，为 BAC 1-11 试验机创造了极佳的测试条件。（Crew chiefs prepare to launch their BAC 1-11 aircraft for a mission June 18, 2009 during Exercise Northern Edge 09 held at Elmendorf Air Force Base, Alaska. The BAC 1-11 is flying missions during Northern Edge to test the F-35 Joint Strike FighterÕs APG-81 radar. Northern Edge is the largest most complex airborne electronic warfare environment and is AlaskaÕs largest military training exercise that prepares joint forces to respond to crises throughout the Asia-Pacific region.）

北部边缘-2008 联合演习中，诺斯罗普·格鲁门公司的 BAC 1-11 试验机准备起飞测试AN/APG-81有源电子扫描阵列雷达和新型机载传感器，它们将装备 F-35 新一代联合攻击战斗机。北部边缘演习包含了几乎所有军兵种参与，为 BAC 1-11 试验机创造了极佳的机载电子战测试环境。（Northrop Grumman's BAC 1-11 test aircraft was equipped with AN/APG-81 AESA radar and AN/AAQ-37 DAS. The white fairings placed on the nose and aft of the nose gear contain the DAS IR sensors mounted in alignment with the viewing angles of the F-35.）

北部边缘-2008 联合演习中，诺斯罗普·格鲁门公司的BAC 1-11试验机准备起飞。该飞机用来测试AN/APG-81有源电子扫描阵列雷达和AN/AAQ-37光电分布式孔径系统，它们将装备在美国新一代联合攻击战斗机F-35身上。通过在BAC 1-11飞行平台上的测试可以大幅度降低联合攻击战斗机项目的风险以及加快项目进度。（The AN/APG-81 active electronically scanned array (AESA) radar and AN/AAQ-37 Distributed Aperture System (DAS) were mounted aboard Northrop Grumman's BAC1-11 test aircraft during the exercise. The radar was tested featuring Block 3 and developmental software, and the DAS was tested with JSF Block 2 delivery software.）
