During the joint patrols in the East China Sea, a drill was held to replenish water and fuel supplies to ships from support vessels, and the transfer of cargo while in motion using the traverse method was also practiced.
The Russian Pacific Fleet's large anti-submarine ship Admiral Tributs interacted with the Chinese People's Liberation Army of China Navy's integrated replenishment ship Taihu. Following parallel courses, the crews practiced synchronizing their speed and maintaining intervals, taking into account the ships' displacement, sea state, and wind speed.
During the drills, sailors from the two countries conducted anti-submarine drills, repelled a mock enemy air attack, conducted rescue drills at sea and honed their skills in taking off and landing helicopters on warship decks.
