The U.S. Army's Reagan Test Site (RTS), located in the Republic of the Marshall Islands, is a premier launch facility based upon its strategic geographical location, unique instrumentation, and unsurpassed capability to support missile testing and space operations.
Kwajalein Atoll consists of just fewer than 100 islands, and the largest is Kwajalein. The Army operates several missile launch sites throughout the atoll. Most test launches support ballistic missile defense programs. The site is attractive not only for its isolation, but also because of its equatorial location, ideal for launches to geosynchronous Earth orbit. With nearly 40 years of successful support, RTS provides a vital role in the research, development, test and evaluation effort of America's missile defense and space program.
