Navy s New Underwater Drone Technology By Martin Holguin January 14, 2014 For years now, the US Air Force has been able to use unmanned aerial vehicles, commonly known as drones, to gain information and accomplish tasks from the sky without putting American lives at risk, and the US Navy has been looking for a way to do the same underwater. And a recent contract announcement with Teledyne Benthos, Inc. reveals we’re closer than ever to having our wish fulfilled. Run by Douglas Webb, the Webb Research division has developed a longendurance underwater Slocum Glider about five feet in length capable of collecting and transmitting information and instructions for weeks or months or even years at a time. Drawing their energy from the oceanic thermocline (layers of warm and cold water near the surface), the gliders’ movement relies on on a process called hydraulic buoyancy, during which changes in water temperature cause changes in density in the glider. As the glider bobs up and down, wings translate this movement into forward momentum of about 1 mile per hour. Information is transmitted via an antenna which periodically breaks the surface with the aid of an air bladder at the tail. The project has been in the works since 2009, and is closer than ever to coming to fruition. A fleet of such gliders could help track down minefields, enemy subs, or simply collect data about water and land properties vital to navigation of larger water crafts. This new technology, once implemented, could save the Navy hundreds of millions of dollars normally spent on traditional, manned surface ships, and could take an increasing number of our Marines out of harm’s way. Lt Cmdr Martin Holguin has served in the United States Navy since 1999 aboard five U.S. warships in positions ranging from division officer to commanding officer. He also served with the Chief of Naval Operations Strategic Studies Group as a Director Fellow. Martin is currently a prospective EMBA candidate at the University of Notre Dame, where he will graduate from in May. For fun and for fitness, Martin enjoys ocean swimming as well as distance running along the coast.

Navy’s  New  Underwater  Drone  Technology  By  Martin  Holguin  January  14,  2014    For  years  now,  the  US  Air  Force  has  been  able  to  use  unmanned  aerial  vehicles,  commonly  known  as  drones,  to  gain  information  and  accomplish  tasks  from  the  sky  without  putting  American  lives  at  risk,  and  the  US  Navy  has  been  looking  for  a  way  to  do  the  same  underwater.  And  a  recent  contract  announcement  with  Teledyne  Benthos,  Inc.  reveals  we’re  closer  than  ever  to  having  our  wish  fulfilled.    Run  by  Douglas  Webb,  the  Webb  Research  division  has  developed  a  long-­‐endurance  underwater  Slocum  Glider  about  five  feet  in  length  capable  of  collecting  and  transmitting  information  and  instructions  for  weeks  or  months  or  even  years  at  a  time.  Drawing  their  energy  from  the  oceanic  thermocline  (layers  of  warm  and  cold  water  near  the  surface),  the  gliders’  movement  relies  on  on  a  process  called  hydraulic  buoyancy,  during  which  changes  in  water  temperature  cause  changes  in  density  in  the  glider.  As  the  glider  bobs  up  and  down,  wings  translate  this  movement  into  forward  momentum  of  about  1  mile  per  hour.  Information  is  transmitted  via  an  antenna  which  periodically  breaks  the  surface  with  the  aid  of  an  air  bladder  at  the  tail.    The  project  has  been  in  the  works  since  2009,  and  is  closer  than  ever  to  coming  to  fruition.  A  fleet  of  such  gliders  could  help  track  down  minefields,  enemy  subs,  or  simply  collect  data  about  water  and  land  properties  vital  to  navigation  of  larger  water  crafts.  This  new  technology,  once  implemented,  could  save  the  Navy  hundreds  of  millions  of  dollars  normally  spent  on  traditional,  manned  surface  ships,  and  could  take  an  increasing  number  of  our  Marines  out  of  harm’s  way.      Lt  Cmdr  Martin  Holguin  has  served  in  the  United  States  Navy  since  1999  aboard  five  U.S.  warships  in  positions  ranging  from  division  officer  to  commanding  officer.  He  also  served  with  the  Chief  of  Naval  Operations  Strategic  Studies  Group  as  a  Director  Fellow.  Martin  is  currently  a  prospective  EMBA  candidate  at  the  University  of  Notre  Dame,  where  he  will  graduate  from  in  May.  For  fun  and  for  fitness,  Martin  enjoys  ocean  swimming  as  well  as  distance  running  along  the  coast.
