'''Panchendriya'''  is a [[sonar]] suite that has been developed by the [[Defence Research and Development Organisation]], [[India]] for the [[submarines]] of the [[Indian Navy]]. It has been described as India's "first indigenously developed sonar system for submarines".<ref>{{cite news|title=New Sonar system to boost Navy's warfare capability|url=http://www.hindu.com/2008/07/02/stories/2008070261560300.htm|archive-url=https://web.archive.org/web/20080705231427/http://www.hindu.com/2008/07/02/stories/2008070261560300.htm|url-status=dead|archive-date=5 July 2008|access-date=8 June 2013|newspaper=[[The Hindu]]|date=2 July 2008}}</ref>
