The United States annexes the Kingman Reef.
Kingman Reef is a largely submerged, uninhabited, triangle-shaped reef, 9.0 nmi (20 km) east-west and 4.5 nmi (8 km) north-south, in the North Pacific Ocean, roughly halfway between the Hawaiian Islands and American Samoa. It has an area of 3 hectares (0.03 km2) and is one of the unincorporated territories of the United States in Oceania. The reef is administered by the United States Fish and Wildlife Service as the Kingman Reef National Wildlife Refuge.
