Dolphin was built as a diesel-electric, deep-diving, research and development submarine. It can carry scientific payloads of over 12 tons, a considerably greater capacity than any other deep diving research vessel. The submarine has internal and external mounting points, multiple electronic hull connectors, and up to 10 equipment racks for project use. Her larger size also provided greater power and on board research personnel than any other deep diving platform. During her 44 year career, she tested advanced submarine structures, sensors, weapons, communications, and machinery systems. Much of her work is still classified, but here are some examples of Dolphin‘s successes:
Dolphin‘s pressure hull is optimized for deepwater operation, it is a constant diameter cylinder, closed at its ends with hemispherical heads, and utilizes deep frames instead of bulkheads. Hull openings have been minimized for structural strength and minimum hull weight, in addition to eliminating possible sources for flooding casualties.
She was donated to Maritime Museum of San Diego in 2008, shortly after undergoing a 50 million renovation following a fire/flooding incident.
