Totally Sweet New Technology


In brand spankin’ new and cool technology news…
The Navy just replaced the Deep Submergence Rescue Vehicle (DSRV) program as the primary deep-sea rescue asset with the Submarine Rescue Diving and
Recompression System (SRDRS).  The DSRV’s were developed

as a result of the sinking of the USS TRESHER in April 1963 (the 13th
submarine of the Navy lost in peacetime), when all hands (129 men) were
lost. After the accident of USS TRESHER the Navy founded the Deep Submergence Systems Review Group
(DSSRG). This group found out that the Navy had no possibility to
rescue sailors located deeper than 330 meters below the water because
this was the maximum range of the McCann – rescue bell. This bell was
first used in 1933 when 33 sailors were rescued out of the submarine

SS SQUALUS in a depth of 73 meters. The group also found out that the
Navy had only primitive means to locate sunken objects and that the
salvage of those objects would almost be impossible.

Out of this came two vehicles, DSRV 1 Mystic and DSRV 2 Avalon. There is a great history of the program and vehicles here.  The SRDRS adds two important capabilities to the Navy’s deep rescue program.  First, the SRDRS is air-transportable and can be deployed off any qualified commercial vessel.  Second, the vehicle permits a pressurized and decompressed transfer of Sailors
rescued from pressurized submarines. 

Also on the wires is news of a new MIT autonomous underwater vehicle (AUV), Odyessy IV, that can hover in place while it examines or interacts with objects.  A capability not present in other AUV’s

Craig McClain is the Executive Director of the Lousiana University Marine Consortium. He has conducted deep-sea research for 20 years and published over 50 papers in the area. He has participated in and led dozens of oceanographic expeditions taken him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses on how energy drives the biology of marine invertebrates from individuals to ecosystems, specifically, seeking to uncover how organisms are adapted to different levels of carbon availability, i.e. food, and how this determines the kinds and number of species in different parts of the oceans. Additionally, Craig is obsessed with the size of things. Sometimes this translated into actually scientific research. Craig’s research has been featured on National Public Radio, Discovery Channel, Fox News, National Geographic and ABC News. In addition to his scientific research, Craig also advocates the need for scientists to connect with the public and is the founder and chief editor of the acclaimed Deep-Sea News (, a popular ocean-themed blog that has won numerous awards. His writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web.

  1. This is is very nifty though i do have to correct you on one thing. The DSRV is an air transportable system as well. To quote

    “When notified of an accident, the DSRVs, the crew and their specialized support gear can be loaded on a C-5 galaxy cargo plane at Naval Air Station North Island and flown to the nearest airport.”

    So that’s pretty air transportable in my opinion. Though any system that could be handled by a smaller airplane or large helicopter would be a significant step up from something moved about by one of the largest aircraft in existence. But I haven’t seen that in any of the reports for this vessel.

    Just an FIY.
