The 552nd Component Maintenance Squadron is a unit of the 552nd Maintenance Group, 552nd Air Control Wing, Tinker Air Force Base, Okla.

The mission of the 552nd Component Maintenance Squadron is to accomplish on- and off-equipment repair of E-3 aircraft and support equipment components and perform maintenance beyond the capability of the Aircraft Maintenance and Equipment Maintenance Squadrons. The unit is responsible for resolving technical problems associated with equipment maintenance, as well as repairing the sophisticated E-3 surveillance radar and computer systems.
The unit provides on- and off-equipment support in the areas of pneudraulics, environmental control systems, electrical systems, fuel systems, surveillance radar, computers, communications, navigation, guidance and control, and electronic warfare systems. Each of these shops provides specialized maintenance skills in the repair of unique equipment required to maintain the fleet of U.S. Air Force E-3s.
Other important functions of the unit are to maintain aircrew proficiency and external testing operations. These functions are supported by the 552nd Component Maintenance Squadron through the maintenance of three mission
simulators, a data display training set, and a facility for interoperability testing. These devices provide realistic training and testing capabilities to ensure mission crew coordination and proficiency to meet worldwide mission requirements.
More than 395 military personnel are assigned to the 552nd Component Maintenance Squadron to ensure the U.S. Air Force's fleet of E-3s remains in a constant state of readiness.

The unit was originally activated December 18, 1954, as the 552nd Electronic Maintenance Squadron. The squadron was inactivated on May 18, 1969 and redesignated as the 552nd Avionics Maintenance Squadron.
The 552nd Avionics Maintenance Squadron was inactivated on April 1, 1975. It was redesignated as the 552nd Component Repair Squadron at Tinker Air Force Base, Okla., on May 15, 1978, and activated on October 1, 1978. The squadron was inactivated at Tinker in May of 1992 as part of Air Force reorganization. It was reactivated May 13, 1996, as an effort to improve E-3 systems efficiency and reliability, and increase the availability of aircraft. July 15, 2002, the unit was renamed the 552nd Component Maintenance Squadron as part of an Air Force reorganization.

The emblem displayed on the front shows a sentry standing watch over the pathway of freedom. The globe and pathway are symbolic of the E-3's contributions to the maintenance of freedom. This is the mission of the 552nd Air Control Wing. In the sentry's hand is a scroll representing the specialized knowledge that members of the 552nd Component Maintenance Squadron require in order to maintain the complex E-3 systems and automatic test equipment. To the sentry's right are an atom and six stars. The atom symbolizes the advanced avionics technology of the complex radar and on-board computer systems, the heart of the E-3 surveillance platform. The stars represent the E-3's ability to perform its mission around the clock, both during the light of day and under the stars of night. A gold bar diagonally separates the ultramarine (night sky) and pale blue (day sky) background. The contrast between the two shades represents the 24-hour vigilance of the E-3.
The readiness of the 552nd Component Maintenance Squadron is such that air commanders throughout the world can rely on Airborne Warning and Control System aircraft to effectively manage their tactical fighter and support forces at any level of military action required.
