The main island of what is usually called Kwaj is home to the missile base known as the United States Army Kwajalein Atoll or USAKA or the Ronald Reagan Ballistic Missile Defense Test Site. Watch a video tour of the base at the bottom of this page.
Mejatto:
This is where members of the Rongelap community were relocated to in 1985. The move was meant to be temporary.
