Kwajalein Atoll
Kwajalein Atoll is an atoll in the Marshall Islands’ Ralik Chain. Its islands host the U.S. Army’s Ronald Reagan Ballistic Missile Defense Test Site.
Ronald Reagan Ballistic Missile Defense Test Site: A U.S. Army installation in the Marshall Islands that supports missile testing, space surveillance, and related missions. Its range facilities occupy islands on Kwajalein Atoll.
Atoll: A ring-shaped coral reef, island, or chain of islands surrounding a lagoon. Kwajalein is a classic example of this reef formation.
Marshallese people: The Indigenous people of the Marshall Islands, with distinct languages and traditions. Marshallese communities have longstanding ties to Kwajalein and its lagoon.
Compact of Free Association: An agreement establishing free association between the United States and the Republic of the Marshall Islands. Its provisions frame U.S. access to military sites and associated financial arrangements.
Vandenberg Space Force Base: A U.S. Space Force installation on the California coast used for launches, testing, and space operations. Unlike Kwajalein, it is a continental launch site with a major coastal range.
Boeing X-37: A reusable, uncrewed U.S. spaceplane operated by the U.S. Space Force. The atoll’s range has supported tracking and recovery operations for X-37 missions.
Ralik Chain: The western island chain of the Republic of the Marshall Islands. Kwajalein belongs to this chain.
Enewetak: A Marshall Islands atoll whose residents were displaced for U.S. nuclear testing. Its displacement history illuminates the unequal burdens of U.S. military use across the islands.
Kwajalein land-use agreement: An agreement governing U.S. use of land on Kwajalein Atoll and payments to Marshallese landowners. It defines the terms under which the test site operates on leased land.
Kauai Test Facility: A U.S. missile-testing facility on Kauai, Hawaii, operated by the Pacific Missile Range Facility. It is another Pacific test range, but is based on a high volcanic island rather than an atoll.
