Ultramarine blue and Air Force yellow are the Air Force colors. Blue alludes to the sky, the primary theater of Air Force operations. Yellow refers to the sun and the excellence required of Air Force personnel. The globe represents the long heritage of the Eastern Launch and Test Range for which the Squadron is responsible. The sine wave represents the electrical signals of the widespread range instrumentation. The gear surrounding the globe represents the engineering and maintenance responsibilities of the unit and skilled technical Squadron personnel. The eight teeth on the gear represent the eight major tracking stations: Ascension, Antigua, Jonathan Dickinson, Patrick, Cape Canaveral, Kennedy Space Center, Wallops Island and Argentina. The deltoid represents the launch vehicles and satellites lofted from the range on an eastward trajectory into space, the basis for the Squadron's mission. The trail from the gear represents the Squadron's technical abilities as the basis for the spacelift mission as well as the effort and passion of the Squadron for accomplishing the mission. The deltoid and contrail also borrow from the heritage of the Long Range Proving Ground emblem, the original predecessor to the 45th Space Wing. The four stars in the heavens represent the four elements of the unit's mission: range operations and maintenance, range modernization and sustainment interface, critical launch facilities operations, and maintenance and quality assurance.
