What is a DSRV (deep submergence rescue vessel)?
- India is one of the few countries in the world that can use a DSRV to search for and rescue a damaged submarine.
- Using its state-of-the-art side scan sonar and remotely operated vehicle, the Indian Navy’s DSRV system can locate a submarine up to 1,000 metres deep.
- Following the good location of the submarine, another DSRV sub module, the submarine rescue vehicle (SRV), connects with the submarine to rescue the trapped personnel.
