Osan Air Base

Team Osan and Why We're Here -- Osan Air Base, located just 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. 

Beginning Thursday, January 20, South Korea will implement stricter entry requirements for off-peninsula arrivals:

All travelers - both new arrivals and returnees - must possess a negative PCR test within 48 hours before the departure date; be advised the PCR test must be performed and the certificate must be issued within the same 48-hour period of departure.

Acceptable PCR tests include NAAT, RT-PCR, LAMP, TMA, SDA and NEAR tests according to the South Korean government: (mofa.go.kr)

Children under the age of 6 (on the date of arrival) are exempt from this requirement if all travelers possesses a valid negative PCR test.

Failure to adhere to this new requirement will result in traveler either being denied entry to board the flight or denied entry into South Korea upon arrival.

Please see the following link to fully understand South Korea’s updated guidance for off-peninsula arrivals to the peninsula: https://overseas.mofa.go.kr/us-en/brd/m_4500/view.do?seq=761034&page=1

Note: Foreign nationals who fail to submit test results will be barred from entering. Korean citizens who do not submit negative PCR test results will be tested at a temporary living facility and be required to self-isolate for 14 days at their own expense. (editor note: ROKG advises this will not be with USFK)

Based on recent ROK policy changes regarding international arrivals, and regardless of vaccination status, all will now be subject to a mandatory 7-day quarantine. Note: This is a change from the previous 10-day mandatory quarantine period that was in effect on Dec. 3.

USFK’s affiliated community and SOFA individuals who have previously established a residence in South Korea are authorized to quarantine in their residence - including on-installation housing, quarters, barracks and dorms - with an approved quarantine action plan signed by a squadron or battalion commander, or civilian equivalent in their chain of command.
