Osan Air Base, located 48 miles south of the Korean DMZ, is home to the "Mustangs" 51st Fighter Wing and 24 tenant units, including Seventh Air Force. As the most forward deployed permanently-based wing in the Air Force, the 51st Fighter Wing is charged with providing mission-ready Airmen to execute combat operations and receive follow-on forces. Our wing with its 24 PAA, F-16 and A-10 squadrons, along with a C-12 airlift flight and a myriad of base support agencies conducts the full spectrum of missions providing for the defense of the Republic of Korea. Every member of the Osan team is vital in maintaining stability in Northeast Asia. Due to our location, critical mission requirements, and continuous turnover; each inbound member must be prepared for quick assimilation and be mission-focused before departing their losing base and soon after arriving at Osan AB, ROK.
