Effective is an MSC-manned ocean surveillance ship that uses primarily the AN/UQQ-2 Surveillance Towed Array Sensor System (SURTASS) to gather underwater acoustical data. The command operates the ship as part of its Special Mission Ships Program, using her to support the antisubmarine warfare mission of the commanders of the Atlantic and Pacific Fleets. In addition, Effective carries electronic equipment to process and transmit that data via satellites to shore stations for evaluation. She is built on a small-waterplane, twin-hull design for greater stability at slow speeds in high latitudes under adverse weather conditions.
