Alddreu Airfield also known as Cheju-do No. 2 (K-40) Air Base was a former Imperial Japanese Navy Air Service and United States Air Force (USAF) air base on southern Jeju Island. It was mostly returned to farm land from the late 1960s onwards, though the site is still owned and used to some extent by the Republic of Korea Air Force, in particular a grass airstrip known semi-officially as Alddreu Airport.


The airfield, then known as Altehru Airfield, was originally developed in 1926-30 during the Japanese Imperial period. Initially, it was primarily used as a refueling station, as well as a base for reconnaissance and maritime patrol aircraft. During the Second Sino-Japanese War it was also used as a forward base of the Omura Naval Air Group for the aerial bombing of cities in China such as Shanghai and Nanjing.[1]

World War II[edit]

Among other things, the base was used for the training of Kamikaze pilots and by the end of the war it housed 2500 naval aviation troops and 25 aircraft in hardened aircraft shelters.

Korean War[edit]

The USAF designated the base as Cheju-do No.2 or K-40. It was apparently mainly used as a refueling & communications facility and came under the umbrella of the 100th Air Base Wing from the 5th of August 1951. Along with an airfield security company of the USAF's Air Police, there were communications, civil engineering, and food service companies permanently based at K-40 during this period.


A TACAN facility was built on the base, now known as Alddreu Airfield, during the early 1960s. Alddreu was handed over by the USAF to the ROKAF in the later part of that decade. The base continues to be owned by the Korean Air Force but has been largely leased to civilians since the time of the handover, with most of the site being currently used as potato fields, though a large number of pre- and post-war facilities are still intact to one degree or another. These include 19 (out of an original 20) World War II aircraft bunkers, and a 1,400-meter grass runway which is still in use as a reserve airstrip by the ROKAF.

Seogwipo City planned at one stage during the late 2000s to develop the area as a theme park.
