DSRV-1 Mystic

DSRV-1 Mystic is a deep-submergence rescue vehicle that is rated to dive up to 5,000 feet. It was built by Lockheed for the US Navy at a construction cost of $41 million and launched 24 January 1970. It was declared fully operational in 1977 and named Mystic.

The submarine was intended to be air transportable; it was 50 feet long and 8 feet in diameter, and it weighed 37 tons. The sub was capable of descending to 5,000 feet below the surface and could carry 24 passengers at a time, in addition to its crew. It was stationed at Naval Air Station North Island in San Diego and was never required to conduct an actual rescue operation. Mystic was replaced by the SRDRS on September 30, 2008 and began deactivation on October 1, 2008. In October 2014, the submarine was donated to the Naval Undersea Museum.
