In 1961 the ship laid communications cable connecting the Pacific islands of Kwajalein, Ennylabegan (one of the islands in the Kwajalein atoll), Gugeegue, Eniwetok and Roi-Namur supporting the Army's then Kwajalein Missile Range, now the Ronald Reagan Ballistic Missile Defense Test Site for Nike Zeus tests. The first phase was laying thirty miles of entrenched cable connecting the islands in the Kwajalein group and then another fifty-five miles of coaxial ocean cable connecting Eniwetok and Roi-Namur to the Kwajalein network. The entrenched cable path had to be first cleared of World War II era ordinance and the trench prepared by Navy underwater demolition team.
