The moment of life and death for the Chinese Navy's 372 submarine has become legendary.

In the history of submarine development, the moment of life and death for the Chinese Navy's 372 submarine has become legendary. This battle of life and death not only tested technology and courage but also examined the strict training and outstanding qualities of every officer and soldier. In the face of the desperate situation of the sea cliff, they showed fearlessness and composure, creating a miracle in world military history. This was not just a self-rescue but also a testament to the confidence and pride of the Chinese Navy, demonstrating its strong capabilities and sense of responsibility on the world stage.
Is this true? Dear audience! Welcome back to our channel! It's a pleasure to engage with you again and discuss today's topic: 1、How is the phenomenon of the sea cliff formed, and what challenge does it pose to submarines? 2、How did the officers and soldiers of the 372 submarine remain calm and take effective measures when facing adversity? 3、What were the biggest difficulties and challenges they faced in this self-rescue operation?
What is a "sea cliff"? It means that the density of seawater is uneven. In some places, the density is high, resulting in greater buoyancy, while in other places, the density is low, resulting in less buoyancy. If a submarine is diving in a high-density layer and suddenly dives into a low-density layer of seawater, buoyancy will sharply decrease, similar to jumping off a cliff on land. The submarine will rapidly sink, with every 10 meters of descent increasing pressure by one atmosphere. If it cannot self-rescue and resurface within a few minutes, it will sink to the seabed, crushed by immense pressure. This phenomenon, also known as "diving deep," is a perilous situation that terrifies all submarines worldwide and makes survival extremely difficult.
In history, the Israeli submarine Dakar and the U.S. submarine Thresher both met their demise after encountering the "sea cliff." They permanently sank to the seabed, with all crew members perishing. Meanwhile, the Thresher carried 22 nuclear missiles, all of which disappeared. Only China's 372 submarine, in a span of three minutes between life and death, accurately executed over 30 commands and flawlessly completed more than 500 actions, creating the unique miracle in world military history of successfully self-rescuing from being stuck in a sea cliff.
On February 2, 2014, at midnight, the Navy's 372 submarine was cruising in the depths of the ocean. Most of the 69 officers and soldiers on board were immersed in the joy of the Spring Festival, unaware that they were about to encounter the unprecedented sea cliff in world military history. At 00:29, the depth gauge of the 372 submarine suddenly fluctuated violently. Accompanied by a piercing alarm and the cry of the deputy commander, they fell into the terrifying sea cliff. The time left for all officers and soldiers to save the 372 submarine was only a short three minutes. The captain realized that this was a life and death moment for the
