DSRV-1 Mystic is a Deep Submergence Rescue Vehicle. It was built by Lockheed for the U.S. Navy at a construction cost of $41 million and launched 24 January 1970. It was declared fully operational in 1977 and named Mystic.

DSRVs were designed for quick deployment in the event of a submarine accident and are transportable by truck, aircraft, ship, or specially configured attack submarine. 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.

Propulsion and control of the DSRV is provided by a conventional, battery–powered, stern propeller in a movable shroud; and four ducted thrusters, two forward and two aft. The system permits the DSRV to maneuver and hover in underwater currents. The DSRV can attach to a submarine inclined to angles up to 45 degrees from vertical in either the fore and aft or athwartships direction, and exposed to a current of up to 2 knots.

The Mystic was was never required to conduct an actual rescue operation and was replaced by the SRDRS on September 30, 2008. The submarine was donated to the Naval Undersea Museum. [Wikipedia, Navy.mil, bremolympicnlus.wordpress.com]
