Japanese Military Builds Pyeongtaek Airfield

The Imperial Japanese military constructed an airfield at Pyeongtaek that would become the physical foundation of what is today Camp Humphreys. This early infrastructure was the seed from which the entire garrison eventually grew, as the site's flat terrain and strategic location on the Korean peninsula made it valuable to successive military powers for over a century.

K-6 Airfield Supports Korean War Operations

During the Korean War the U.S. Air Force repaired and upgraded the Pyeongtaek airfield, designating it K-6. It hosted U.S. Marine Corps Air Group 12 and the 6147th Tactical Control Group, making it an active combat-support hub that transformed the installation from a dormant Japanese-built field into a functioning U.S. military asset in the Republic of Korea.

Post Renamed Camp Humphreys

The base was officially renamed Camp Humphreys in honor of Chief Warrant Officer Benjamin K. Humphreys, a pilot with the 6th Transportation Company who died in a helicopter accident in Korea. The renaming formalized the installation's identity as a permanent U.S. Army presence on the peninsula and marked a transition from a temporary wartime airfield to a named, standing garrison.

U.S.–South Korea Expansion Agreement Signed

The United States and South Korean governments reached an agreement to consolidate all U.S. forces south of the Han River, with Camp Humphreys designated as the primary hub. The deal called for relocating U.S. Forces Korea, Combined Forces Command, and United Nations Command headquarters from Seoul's Yongsan Garrison to Pyeongtaek, with South Korea funding the lion's share of an approximately $10.8 billion expansion.
