"In August 1969, Dolphin launched a torpedo from the deepest depth that one has ever been fired. Other examples of Dolphin's work include
first successful submarine-to-aircraft optical communications
development of a Laser Imaging system of photographic clarity
development of an Extreme Low Frequency (ELF) antenna for Ohio-class submarines
evaluation of various non-acoustic ASW techniques
evaluation of various low probability of interception active sonars
first submarine launch of a mobile submarine simulator (MOSS) system
first successful submarine test of BQS-15 sonar system
development of highly accurate (10 cm) towed body position monitoring system
development of a new Obstacle Avoidance Sonar system
development of a highly accurate target management system
evaluation of a possible "fifth force of nature"
first successful submarine-to-aircraft two-way laser communication
deepest submarine dive- more than 3,000 feet.[3]
Dolphin was overhauled in 1993.
In the late 1990s, Dolphin tested a new sonar system. As a result of Dolphin's efforts, this new system will now be retrofitted into the fleet."
