She is now known only by its hull number, not by its former name.
DSV-4 is an Alvin-class Deep Submergence Vehicle (DSV). a sister ship to DSV TURTLE (DSV-3) and DSV ALVIN (DSV-2). The Alvin-class DSVs were designed to replace older DSVs, such as the less-maneuverable Trieste-class bathyscaphes.DSV-4 originally had a maximum dive depth of 6,500 feet (2,000 meters), as all Alvin-class DSVs did at first. It was redesigned to dive to 20,000 feet (6,096 meters) and refitted in 1984. With the refit of DSV-4, the bathyscaphe DSV-1 (ex-TRIESTE II) was retired from service.
DSV-4 has a plug hatch 2 feet (0.61 meter) in diameter, held in place mechanically with hatch dogs and, while submerged, by the pressure of the water above it. DSV-4 can dive 5,000 feet (1,524 meters) deeper than the famed ALVIN; however, the Super ''Alvin''-class replacement for DSV-2 is designed to dive to 22,000 feet (6,705 meters).
SEA CLIFF was retired from active service in 1998 and subsequently given to Woods Hole Oceanographic Institution. The Naval Vessel Register shows DSV-4 was returned to active U.S Navy service on 30 September 2002 in the custody of Woods Hole, but a New York Times article indicates that it was cannibalized for parts for DSV ALVIN.
2016 So far I can find out she is still in a dry-berth stored at Woods Hole.
