'''''Prevail'' (IX-537)''' is a modified {{sclass|Stalwart|ocean surveillance ship|0}} auxiliary general [[ocean surveillance ship]] (AGOS) of the [[United States Navy]] previously operated by the [[U.S. Military Sealift Command]] as T-AGOS 8.  ''Prevail'' was reclassified as Unclassified Miscellaneous (IX) in October 2003 and is unofficially referred to as TSV-1.  In this context, TSV stands for Training Support Vessel, and should not be confused with the U.S. Army's {{USAV|Spearhead}} Theater Support Vessel initiative.

''Prevail'' is currently assigned to [[Commander Strike Force Training Atlantic|Commander, Carrier Strike Group Four]] and is operated with a minimal, hybrid crew of civil service and contract mariners.  The ship provides a dedicated training support for Strike Group training for [[U.S. Atlantic Fleet]] ships, including serving as a platform for training [[Visit, Board, Search, and Seizure]] (VBSS) operations.

''Stalwart''-class ships were originally designed to collect underwater [[acoustical data]] in support of [[Cold War]] [[anti-submarine warfare]] operations in the 1980s.

==Design==
The [[Stalwart-class ocean surveillance ship|''Stalwart''-class ocean surveillance ships]] were succeeded by the longer [[Victorious-class ocean surveillance ship|''Victorious'' class]]. ''Prevail'' had an overall length of {{convert|224|ft|m}} and a length of {{convert|203|ft|6|in|m}} at its waterline. It had a [[beam (ship)|beam]] of {{convert|43|ft|m}} and a [[draft (ship)|draft]] of {{convert|15|ft|m}}. The surveillance ship had a displacement of {{convert|1600|t|LT ST}} at light load and {{convert|2301|t|LT ST}} at full load. It was powered by a diesel-electric system of four Caterpillar D-398 diesel-powered generators and two [[General Electric]] {{convert|550|PS|shp kW}} electric motors. This produced a total of {{convert|3200|PS|shp kW}} that drove two shafts. It had a [[gross register tonnage]] of 1,584 and a deadweight tonnage of 786.<ref name="Polmar2005">{{cite book|author=Norman Polmar|title=The Naval Institute Guide to the Ships and Aircraft of the U.S. Fleet|url=https://books.google.com/books?id=8MwyTX-iA2wC|year=2005|publisher=Naval Institute Press|isbn=978-1-59114-685-8|page=617}}</ref>

The Stalwart-class ocean surveillance ships had maximum speeds of {{convert|11|kn|km/h mph}}. They were built to be fitted with the [[Surveillance Towed Array Sensor System]] (SURTASS) system. The ship had an endurance of thirty days. It had a range of {{convert|3000|mi|nmi km}} and a speed of {{convert|11|kn|km/h mph}}. Its complement was between thirty-two and forty-seven. Its hull design was similar to that of the {{sclass|Powhatan|tugboat}}s.<ref name="Polmar2005"/>
