U.S. Army Garrison Kwajalein Atoll

U.S. Army Garrison Kwajalein Atoll at a glance

U.S. Army Garrison Kwajalein Atoll provides installation support for a remote Pacific community and its joint and multinational mission partners. The atoll is also home to the Army's principal space and missile test range, where public descriptions identify radar, optical and telemetry instrumentation used for testing and space-related research.

The range's name changed in 2026 to the Ronald Reagan Space and Missile Test Range, replacing the former Reagan Test Site designation. Official Army reporting explains that the new name reflects its long-standing space and missile testing responsibilities. The garrison and range should be distinguished: one sustains the installation community and coordinates support, while the other carries out specialized technical missions. Both operate within the Republic of the Marshall Islands.
