Sword Knot, assigned to the South Atlantic Ocean and the Caribbean area, provided the Air Force with metric data on intercontinental ballistic missiles launched from the Cape Canaveral Air Force Station (CCAFS) in Florida as part of the Missile Test Project. It operated in the intercontinental ballistic missile re-entry area near Ascension Island, and was home-ported out of Recife, Brazil.

After transfer to the U.S. Navy's Military Sea Transportation Service, Sword Knot was reassigned to the Western Range and home-ported in Port Hueneme, California. There, she provided data on missiles launched from Vandenberg Air Force Base.
