Naval Base Funafuti was a naval base built by the United States Navy in 1942 to support the World War II effort. The base was located on the Island of Funafuti of the Ellice Islands in the Western Pacific Ocean. The island is now Tuvalu, an island country in the Polynesian. After the surprise attack on Naval Station Pearl Harbor on December 7, 1941, the US Navy was in need of setting up more advance bases in the Pacific Ocean. At Naval Base Funafuti the Navy built a sea port, a small hospital, PT boat base, a seaplane base and an airbase.
