The U.S. Navy has ordered its Undersea Rescue Command based in San Diego to deploy to Argentina Nov. 18, to support the South American nation's ongoing search for the Argentinean Navy submarine A.R.A. San Juan in the Southern Atlantic. URC is deploying two independent rescue assets based on a number of factors, including the varying depth of ocean waters near South America's southeastern coast and the differing safe operating depths of the two rescue systems.
