Commitment Remains: U.S.-ROK
The wartime alliance between the United States and the Republic of Korea continued after the armistice as a long-term defense partnership. The armistice stopped large-scale fighting but did not produce a peace treaty. American and South Korean forces therefore continued training, planning, and maintaining readiness on a peninsula that remained divided by the Demilitarized Zone.
In depth
The story behind the display
The Mutual Defense Treaty signed in 1953 gave the alliance a formal framework. Aircraft, bases, joint exercises, intelligence, logistics, and diplomacy have changed across generations, but the unresolved political division created by the war remains central to the relationship.
History & service
The legacies of the Korean war are lasting commitment to democratic ideals and steadfast action to stop aggression. In the decades since the war, the Republic of Korea has grown into a modern, free and vibrant industrial nation. The foundation of South Korean freedom lies in the sacrifice of its people, and in the strong support of fellow democratic nations in war and peace.
American defense and political commitment to South Korea remains strong. As communist North Korea has demonstrated through the years, it still poses a threat to peace and democracy in the region. Serious incidents including murders in the Demilitarized Zone and the illegal capture of the American naval vessel USS Peublo -- plus innumerable threats of military action -- have proven that North Korean hostility is still a grave danger. Strong U.S.
forces therefore remain in partnership with the Republic of Korea's defense establishment.
The United States Air Force maintains a robust presence on the Korean peninsula. The 7th Air Force's 51st and 8th Fighter Wings operate from Osan and Kunsan Air Bases, with support units at several other South Korean locations. Bolstering U.S. air power in the region, Pacific Air Forces also are present in Japan, Hawaii, Guam and Alaska. Overall, the U.S. has around 28,500 service members stationed in South Korea, including about 20,000 U.S. Army Soldiers.
Naval and Marine forces that also play key roles in Pacific regional defense.

Air power in a limited war
The Korean War brought early jet combat into the same theater as piston fighters, large bombers, helicopters, and transports. Different technologies served different needs. Fast fighters contested the air, while other aircraft attacked supply routes, supported troops, carried equipment, gathered information, and evacuated casualties. The mountainous terrain and severe weather made those tasks especially demanding.
The conflict also exposed the limits of air power used within a larger political and military struggle. Aircraft could damage bridges and transportation networks, but opposing forces adapted, repaired, dispersed, and moved under cover. Supporting troops required communications and coordination close to the ground. Maintaining operations depended on suitable bases and an extensive flow of supplies.
The surviving artifacts show why a gallery cannot be understood through jet fighters alone. A tent, vehicle, radio, flight nurse's equipment, or rescue helicopter belongs to the same operational history. The stories of individual airmen are compelling because they took place within that complicated setting. Cross-links to the Second World War and later Cold War galleries reveal both continuity and change: familiar aircraft found new roles, jet performance expanded, and rescue systems developed further. The war ended in an armistice, making its history one of service and sacrifice within an unresolved division as well as one of technological change.
