The 437th Maintenance Squadron (MXS) consist of seven flights which include 14 unique sections. Our vision of “Ready Airmen protecting our nation’s promise around the world” drives us to execute our no-fail, global mission through safe, precise, reliable, mission-ready equipment and aircraft…anytime, anywhere. MXS is composed of 440 combat-ready maintainers and support personnel, comprised of Active Duty, Civilian, and Air Reserve Technician components. They inspect, service, maintain, and support assigned C-17 aircraft and associated equipment at Joint Base Charleston. These maintainers enable aircraft to perform global airlift missions ranging from combat support operations and humanitarian relief to aeromedical evacuations. The squadron is also responsible for aircraft maintenance around the world through AEF and short-notice deployments in support of any mission, anywhere.
The 437th Maintenance Squadron is responsible for the maintenance of 40 assigned C-17A aircraft worth more than $9 billion dollars. MXS primarily performs back shop and flightline support to include structural, avionic, hydraulic, electrical, environmental, and fuels maintenance. Additionally, we conduct scheduled Home Station Check (HSC) inspections, Non-Destructive Inspections (NDI), and Aerospace Ground Equipment (AGE) support. Our world-class Precision Measurement Equipment Laboratory supports Test Measurement & Diagnostic Equipment maintenance for the entire region. Furthermore, our maintenance flight produces time critical wheel and tire assemblies for locations around the world, and stands always ready to support regional civil and military aviation mishaps with a Crashed, Damaged, Disabled, Aircraft Recovery team. Finally, our Munitions Flight is responsible for inspecting, shipping, and maintaining a revolving munitions stockpile of approximately 725 munitions line-items valued at $7.1M in support of Wing’s C-17 mission, as well as, 28 joint base munitions supply points.
With each and every day that passes, the "Mavericks" continue to innovate processes and procedures, exuding squadron's slogan of "Mavericks…Make It Happen!" That slogan, and its underlying themes, run rampant throughout the squadron and are embraced by the outstanding personnel assigned. Daily we achieve phenomenal successes despite flying the oldest C-17s in the fleet. We do it through teamwork and by readiness spurred by the synchronization of correct 4Ts; Tools, Time, Tech Data, and Training.
Our mission statement, " Safe, precise, reliable, mission-ready equipment and aircraft…anytime, anywhere," captures the spirit of what we do, the diverse support we provide, and reflects the enormous scope of operations these squadrons support. It recognizes that our efforts are not limited to the 437th/315th Airlift Wings or even to Air Mobility Command (AMC), but around the globe supporting the Air Force's Global Reach doctrine and mission.

Emblem (Approved on 29 April 2013)
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 background of day and night sky indicates around-the–clock maintenance operations. The sun resembles a compass rose, symbolizing the Squadron’s mission of support in keeping the unit’s aircraft flying worldwide. The stars are in a constellation cluster, representing the teamwork required among Active Duty and Air Reserve component officer and enlisted members and civilians to make the mission happen.
