Russia and Vietnam conducted exercises at Cam Ranh Port to locate distressed submarines resting on the seabed. The drills involved the Russian Project 636.3 submarine *Ufa* and the Project 21300 *Delfin* rescue vessel *Igor Belousov*, as well as the Vietnamese Project 636.1 submarine *Ho Chi Minh* and the multi-purpose search-and-rescue vessel *Yet Kieu*. According to the exercise scenario, the *Ufa* and the *Ho Chi Minh* simulated an emergency situation. Rescue vessels from both nations located and inspected the submarines using remotely operated deep-sea vehicles. The crew of the *Igor Belousov* deployed the *Pantera Plus* underwater vehicle to inspect the submarine, while Vietnamese rescue teams carried out similar operations on the Russian submarine.
