The Ronald Reagan Ballistic Missile Defense Test Site, commonly known as the Reagan Test Site (RTS), is a sprawling missile test range and space research facility located in the Marshall Islands in the Pacific Ocean. Covering an area of approximately 750,000 square miles, this expansive complex serves as a vital testing ground for U.S. missile defense systems and space research programs. The site’s strategic location and advanced instrumentation make it an invaluable asset for the Department of Defense and various government agencies involved in missile technology development and space operations.
Historical Background
The origins of the Reagan Test Site can be traced back to the early 1960s when the U.S. military recognized the need for a remote location to conduct missile testing and space research. The Kwajalein Atoll, with its isolated position in the Pacific Ocean, was selected as an ideal site for these activities. Initially known as the Kwajalein Missile Range, the facility has undergone several name changes and expansions over the decades.
In the early years, the site played a significant role in Project PRESS (Pacific Range Electromagnetic Signature Studies), which focused on developing instrumentation to characterize the flight tests of newly developed long-range missiles and strategic missile defense systems. The involvement of the MIT Lincoln Laboratory in the 1960s marked the beginning of a long-standing scientific partnership that continues to this day.
Over time, the range’s capabilities expanded, and its mission evolved to encompass a broader scope of activities, including space surveillance and satellite tracking. In recognition of its importance to national defense, the facility was renamed the Ronald Reagan Ballistic Missile Defense Test Site in 1999.
