Historical Overview of USS Dolphin
Construction and Commissioning
The USS Dolphin was conceived as a research and development platform for the U.S. Navy under project SCB 207. Built at Portsmouth Navy Yard in Maine, her keel was laid in 1962, launched in 1968, and she entered service later that year. Her hull number, “555,” was drawn from a canceled block of WWII-era Tench-class submarines (GlobalSecurity.org).
Design and Capabilities
Dolphin’s hull—crafted from HY-80 steel with a unique ring-stiffened, bulkhead-free design—enabled world-record-setting dives. She measures 165 feet long, with an 18-foot beam, displacing 860 tons surfaced. Her diesel-electric propulsion allowed quiet, precise maneuvering and supported a scientific payload over 12 tons, with room for 21 crew and up to four scientists (Defense Media Network).
Record-Setting Achievements
Immediately after commissioning, Dolphin set a world record by diving beyond 3,000 feet—a feat unmatched by any other operational submarine (Reddit). She was also the first to launch a torpedo at extreme depths and played a pivotal role in laser communication, sonar, and advanced imaging systems.
Research and Operational Role
Dolphin operated as a testbed for sonar, weapons, communications, and rescue systems. She supported both military and civilian scientific research, including collaborations with NOAA and academic institutions. Her missions advanced submarine technology, oceanography, and safety for all undersea operations (GlobalSecurity.org).
Notable Incidents
In May 2002, Dolphin survived a major flooding and fire incident caused by a torpedo shield door gasket failure. The crew’s rapid response saved the vessel and all aboard, earning commendations for heroism. After extensive repairs, she returned to duty in 2005 before decommissioning in 2007.
Decommissioning and Museum Ship Status
Retired as the last diesel-electric submarine in U.S. Navy service, the USS Dolphin was transferred to the Maritime Museum of San Diego in 2008 and opened as a museum ship in 2009. She is now an educational centerpiece, illustrating the evolution of deep-sea research and submarine technology (Reddit).
