Significance
The centrally dominant globe of the AFSPC Emblem represents the earth as viewed from space, the earth being both the origin and control point for all satellites. The lines of latitude and longitude emphasize the global nature of Air Force space operations.
The emblem is provided its distinctive appearance by two symmetric ellipses representing the orbital paths traced by satellites in earth orbit, the satellites themselves being symbolically depicted as four-point stars.
The 30-degree orbital inclination and symmetrically opposed placement of the satellites signify the worldwide coverage provided by Air Force satellites in accomplishing space-based surveillance, navigation, weather, missile warning and communications missions. The slight tapering of the orbital ellipses represents the characteristic eastward motion.
The centrally superimposed deltoid symbolizes both the Air Force upward thrust into space and the launch vehicles needed to place all satellites in orbit. The distinctive dark blue background shading and small globe and stars symbolize the space environment.
