Alvin, first of its ship class of deep submergence vehicle (DSV), was built to dive to 2,440 metres (8,010 ft). Each of the Alvin-class DSVs have different depth capabilities. However, Alvin is the only one seconded to the National Oceanic and Atmospheric Administration (NOAA), with the others staying with the United States Navy.
DSV-4 is an Alvin-class deep submergence vehicle (DSV), a sister ship to Turtle and Alvin. The Alvin-class DSVs were designed to replace older DSVs, such as the less-maneuverable Trieste-class bathyscaphes. Sea Cliff was built by Electric Boat in Groton, Connecticut for the U.S. Navy and was completed in December 1968.
MV Dolores Chouest is a specifically built surrogate ship, to DSV Alvin-class submersibles and other military rescue ships.She provides surface support for special warfare exercise missions, submarine sea trials/deep dives, naval mine recovery operations (inert mines only) and unmanned vehicle operations and mother ship support for submarine rescue chamber operations.
Another Alvin-class DSV sub, launched in December 1968, retired in 1998, and returned to active service in September 2002. Since 1981, Sea Cliff has a depth capability of 6,000 m (20,000 ft), [5] and is owned and operated by the United States Navy.

Among the most well-known and longest-in-operation submersibles is the deep-submergence research vessel DSV Alvin, which takes 3 people to depths of up to 4,500 metres (14,800 ft). Alvin is owned by the United States Navy and operated by WHOI, and as of 2011 had made over 4,400 dives. [8]
NEMO was found to be an effective observation platform, despite not being able to hover in place, and acrylic-hulled submersibles have continued to be built and operated in the United States. NEMO is considered part of the Alvin class of Deep Submergence Vehicles despite bearing little resemblance to the other subs of the class.
