Diving Systems Support Detachment

The DSSD detachment is the one with the longest historical background. Well before the loss of the USS Thresher prompted the forming of the Deep Submergence Unit, Diving Systems Support Detachment's progenitors were saving submariners from unfortunate mishap.

In the 1930s a Navy commander, A. E. McCann, helped build the McCann/Erickson rescue chamber, what is now known as the submarine rescue chamber (SRC). This was done in response to the loss of the USS S-4 earlier in the decade. Work on the rescue chamber was completed just in time, too, because in 1939, USS Squalus went down. This time, however, the Navy was prepared. McCann and his Experimental Diving Unit were dispatched to rescue the Sailors and bring them home to safety. This is what he did and because of his innovations, 33 of the 53 Sailors aboard Squalus were saved. This is the history of the rescue chamber's current home, Diving Systems Support Detachment (DSSD).

The unit now operates out of the DSU compound on Naval Air Station North Island. They have three SRCs and little has changed since their initial development in the '30s.

Also, DSSD operates as the underwater rigging experts for recovery operations. Working hand-in-hand with the other units within DSU, DSSD helps to rig objects for recovery by the underwater robots of Unmanned Vehicles Detachment.
