In 1952, upon signing the Treaty of San Francisco, Japan renounced its claim to the island. Soviet Border Troops occupied the former Japanese military facilities. As early as the 1950s, a P-14 radar "Tall King" VHF air defense radar existed on the far northeastern tip of Urup Island. A lighthouse was built on Mys Kastrikum (the easternmost cape) by Soviet authorities, as well as another on the western cape, Mys Chyeryepakha. The troops were withdrawn upon the dissolution of the Soviet Union in 1991, the co-located airfield was turned into a bombing range.
