Indian Navy dispatched its Deep Submergence Rescue Vessel (DSRV) on Thursday to assist Tentara Nasional Indonesia-Angkatan Laut (TNI AL - Indonesian Navy) in search and rescue efforts for the Indonesian Submarine KRINanggala which was reported missing on Wednesday 21 Apr 21.

The submarine was reportedly exercising in a location 25 miles North of Bali with a crew of 53 personnel.

Indian Defence Minister Rajnath Singh had a telephonic conversation with the Indonesian Defence Minister Gen Prabowo Subianto, today.
 
Singh said, “I am extremely pained to hear about the missing Indonesian Submarine Nanggala with 53 crew on board.... At this point I would like to extend the full support of the Indian Armed Forces to the Indonesian Rescue effort.”

“I have already directed the Indian Navy to move its Deep Submergence Rescue Vessel (DSRV) to Indonesia. I have also tasked the Indian Air Force to see the feasibility of induction of the DSRV intervention system by air”.  

“India is committed to assist our strategic partners during times of necessity," Singh assured his Indonesia counterpart.

India is amongst the few countries in the world capable of undertaking Search and Rescue of a disabled submarine through a DSRV. Indian Navy’s DSRV system can locate a submarine upto 1000 meter depth utilising its state of the art Side Scan Sonar (SSS) and Remotely Operated Vehicle (ROV). After the submarine is successfully located, another sub-module of DSRV- the Submarine Rescue Vehicle (SRV) - mates with the submarine to rescue the trapped personnel. The SRV can also be used to provide emergency supplies to the submarine.

Under the framework of comprehensive strategic partnership between India and Indonesia, Indian Navy and Indonesian Navy share a strong partnership of operational cooperation. The two navies have been exercising regularly in the past and have developed synergy and interoperability which is considered important for the present mission.
