Kwajalein Atoll consists of 97 islands with a total land mass of just 6.5 square miles, surrounding an immense 1,100-square-mile lagoon — the largest coral atoll in the world. It is not much of a tourist draw; the biggest island is owned by the US Army and the smaller islands are not particularly interesting either. The closest thing to a tourist attraction is the possibility of diving for World War II shipwrecks.
The atoll is used by the US Army for testing intercontinental ballistic missiles fired from Vandenberg Air Force Base in California, 4,200 miles away. The tests generally occur at night, often lighting up the sky with a brilliant display of explosions, burning debris, and sonic booms.
About 3,000 Americans live on Kwajalein Island, the largest in the atoll. The island is off limits to unofficial visitors except as a transit point to neighbouring Ebeye Island, home to about 1,500 Marshallese labourers who work on Kwajalein but are not allowed to live, shop, or play there.
