A reader (Officer onboard submarine in European Navy) tells me I am probably wrong saying the sonar is H/SJG-206. He says H/SJG-206 is a towed array rumored to be based on SQR-19. According to him, 056A VDS could be called ESS-1 based on DUBV 43.
Thoughts ?
i'm not sure PLAN has been very forthcoming with the official designation of the sonar equipment they use.
