At this time, the other two old submarines had already entered the water and were lurking in the distance waiting for the arrival of the first generation of the Q-Series offensive nuclear submarines.
They were used to test the underwater decibel effect of the Q-Series nuclear submarines. Currently, the underwater noise of the old model could reach 105 decibels.
If the noise of the first generation of the Q-Series offensive nuclear submarines could be lower than 105 decibels, then the old model submarines would not be able to detect the existence of the first generation of the Q-Series offensive nuclear submarines at all!
At this time.
The voice of the commander of the first generation of the Q-Series offensive nuclear submarines came one after another from the big screen.
"Diving depth 100 meters, water pressure 1."
"0 bar, water temperature 22 degrees."
"Power reactor normal current speed 24."
