Osan Air Base

Osan Air Base at a glance

Osan Air Base is the home of the 51st Fighter Wing and a community of additional Air Force and other military organizations in South Korea. Its mission centers on ready forces for defense of the Republic of Korea and the ability to receive and sustain follow-on forces. The base's wider installation work supports the aircraft, people and organizations carrying out those responsibilities.

The wing's lineage reaches back to 1948 and includes service at several Pacific locations. Its history at Osan includes assumption of host responsibilities in 1971 and later changes in mission and organization. Although the base is named Osan, official installation information places it in Pyeongtaek. That distinction matters for researching the surrounding community and separating the air base from nearby Camp Humphreys.

Before you arrive

Use these questions with your sponsor or gaining organization. They are a starting point for planning, including assignments, courses and training periods that differ from a routine permanent change of station.

1. Confirm the organization, duration and reporting instructions shown on your orders. Ask which office handles your arrival.
2. Clarify lodging and housing arrangements before booking. Ask about availability, required approvals and how to handle a late arrival.
3. For an overseas assignment, ask your sponsor about family travel authorization, required documents, medical screening, pets and vehicle shipment before making reservations.
4. Coordinate household goods and personal travel with the appropriate transportation office. Keep orders, receipts and important family records together.
5. Make a short list of contacts for medical care, schools, childcare and family support, where applicable to your assignment.
