Kwajalein Atoll
Marshall Islands
Atoll·Strategic, Remote, Historic
Kwajalein Atoll is one of the world's largest coral atolls, located in the Ralik Chain of the Marshall Islands. It is most famous for its role as the Ronald Reagan Ballistic Missile Defense Test Site and its long-standing history as a U.S. naval base since World War II. The landscape is a unique juxtaposition where high-tech radars and space launch facilities sit alongside historic relics, including the wreck of the German cruiser Prinz Eugen. While the southernmost island of Kwajalein serves as the main residential hub for U.S. personnel, the entire atoll offers the serene, isolated beauty of the central Pacific, characterized by vast lagoons and vibrant coral reefs.
