The US Navy 7th Fleet was formed in Brisbane in 1943 at the headquarters of General Douglas MacArthur in what is now MacArthur Chambers in the city's CBD.
MacArthur was the commander of the Allied forces in the south-west Pacific.
The 7th fleet, featuring several Australian naval ships, fought at the Battle of Leyte Gulf in the Philippines in 1944 - the largest naval battle of World War II.
The fleet has since served in the Korean, Vietnam and Gulf Wars and is currently based in Japan.
