It was soon apparent that the Navy's practice of short term tours and transfer out of the system was a problem. Commander Ocean Systems Atlantic launched an effort in 1964 to create a rating peculiar to SOSUS and allow personnel to remain within the community. It took five years for Bureau of Personnel to create the rating of Ocean Technician [OT].
The new Stalwart-class ocean surveillance ships had the first contract awarded on 26 September 1980 and were similar to the prototype ship, the Moana Wave. Initially the SURTASS system were passive, receiving only sonar systems. The array was towed miles behind the ships and were designed for long range detection of submarines.
The National Ocean Service (NOS) is an office within the U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA). It is the responsible for preserving and enhancing the nation's coastal resources and ecosystems along approximately 95,000 miles (153,000 km) of shoreline, that is bordering 3,500,000 square miles (9,100,000 km 2) of coastal, Great Lakes, and ocean waters.
The Navy placed the ship in non-commissioned service in the Military Sealift Command on the day of her delivery as USNS Vindicator (T-AGOS-3).Designed to collect underwater acoustical data in support of Cold War anti-submarine warfare operations using Surveillance Towed Array Sensor System (SURTASS) sonar equipment, Vindicator spent the final years of the Cold War searching for Soviet Navy ...
the depth (range) of the bottom of the river, lake, or ocean below the transducer. Range the distance between the transducer and the "target" (fish, zooplankton, vegetation, bottom). This is determined by precise timing from sound generation to sound reception (by the transducer). Bottom type; Seabed type; Substrate type; or Sediment type
During the spring and summer of 2004, Impeccable conducted five training missions in the Philippine Sea and the northwest Pacific Ocean. All LFA sonar operations included the operation of the High Frequency / Marine Mammal Mitigation sonar and compliance with all mitigation requirements.

both passive and active low frequency sonar arrays USNS Effective (T-AGOS-21) is a Victorious -class ocean surveillance ship acquired by the U.S. Navy in 1993 and assigned to the Navy's Special Mission Program.
Their original purpose was to collect underwater acoustical information using the Surveillance Towed Array Sensor System (SURTASS), a towed array passive sonar. Stalwart , Indomitable , and Capable were modified to support narcotics interdiction by removing SURTASS equipment and adding an air-search radar and tactical data link equipment .
