I have no idea what you call them but searching the official website gave me this answer...lol. The above display is that of a G550-AEW escorted by four F5 fighter planes. The G550-AEW is able to detect, identify and track aerial targets from a longer range. Now I sounded so smart...hahaha.
You can read more about the display of planes from the official website of NDP 2010.
