USAS American Mariner
The USAS American Mariner was a U.S. Army research vessel from January 1959 to 30 September 1963. She was originally assigned to DAMP Project by the Advanced Research Projects Agency (ARPA) to attempt to collect radar signature data on incoming intercontinental ballistic missiles in the Caribbean, the South Atlantic Ocean, and the Indian Ocean. Her initial operations involved providing radar track on the Atlas missile, which was under development at the time. Subsequently, she provided track on other types of missiles as they proceeded through their development and operational stages.
