The most prominent island in the Kwajalein Atoll. It's also known as U.S. Army Kwajalein Atoll (USAKA), home to Ronald Reagan Ballistic Missile Defense Test Site at Kwajalein Atoll (RTS). This operates as a subordinate command of the U.S. Army Space and Missile Defense Command. A major weapons company gets contracted to run the actual missions. Last year it was Raytheon, but now it is Kwajalein Range Services (KRS). The total population fluctuates from 2,000 to 5,000 people and are mostly employees of the company in charge. Local Marshallese people are allowed on the island during the day to work, but must leave before nightfall. The island is complete with 80 degree weather year round, an outdoor movie theatre, library, and ocean-side pools.
