It is a constant diameter cylinder, closed at its ends with hemispherical heads, and utilizes deep frames instead of bulkheads. The single most significant technical achievement in the development of Dolphin is the pressure hull itself. 4 Retirement 5 See also 6 References 7 External links 3 Service Record 3.1 Abandonment at Sea Incident.She is now a museum ship in San Diego Bay under the management of the San Diego Maritime Museum.
