Behind the Cheonan, what is the truth about the Cheonan?

The ammunition close to the bilge in the hull of the ship occurs, and the ammunition in the enclosed space in the bilge will cause the hull to produce the phenomenon of "sagging", resulting in the fracture of the hull, if the amount of ammunition is large enough, it can even blow through the hull at ** to cause a break.

The sinking of the Cheonan refers to the incident on the night of March 26, 2010, when the frigate Cheonan, carrying 104 personnel of the South Korean Navy, suddenly sank to the bottom of the sea while patrolling between Baeknyeong Island and Daqingdao in the Yellow Sea, resulting in the death of 46 officers and men on board. On May 20, a multinational military-civilian investigation team of experts from a multinational group of experts reported allegations that the frigate was torpedoed and sunk by a North Korean submarine.

The "Cheonan" alert ship, also known as the "Cheonan" patrol ship, is an anti-submarine Pohang-class corvette of the Second Fleet of the South Korean Navy, with a displacement of 1,200 tons. On the night of March 26, 2010, the ship was patrolling between Baeknyeong Island and Daeqingdao in the western waters of South Korea, and sank at 21:45 after an unexplained incident occurred at the stern**.

Only 58 of the ship's 104 officers and men survived. After several salvage attempts, the remains of 40 crew members were recovered, and another 6 people are missing. South Korea considers this to be "the largest in the history of the South Korean Navy."

Within the South Korean military, the Cheonan shipwreck was most likely caused by a torpedo-converted rising self-guided mine**. A high-ranking military official explained: "Based on the TOD thermal detector photographs of the sinking process of the Cheonan and the cross-section of the Cheonan ship's breakage, as well as the movements of North Korean submarines and anti-submarine warfare ships, the military claims that the main cause of the Cheonan wreck was the ascending self-guided mine."

The South Korean Joint Staff Headquarters announced on the 5th that South Korea has requested the United States to send experts to assist in investigating the cause of the sinking of the South Korean Navy's "Cheonan" alert ship. The high-level official said: "The fracture part of the Cheonan is in the shape of an entry 'C', and part of the steel plate at the fracture site is inward, and the other part is concave outward.

The reason for the C-shaped shape is that the rising self-guided mine drilled into the interior after colliding with the Cheonan. Commenting on the dent of the steel plate, he said: "This is caused by the bubble ejection phenomenon caused by the firing of mines or modified torpedoes.

Whether it is a mine or a torpedo launched from the bottom of the sea, the phenomenon of bubble jetting is created. According to the different stress points, the ship will rush upward, and at the same time the steel plate will be dented, and then the lower part of the ship will appear hollow, and again in the opposite direction, and finally, the expanded seawater will pour into the interior of the ship due to the action of buoyancy, causing the steel plate to sink upwards again. And at this time the ship was broken in two.

The military believes it is highly likely that ordinary North Korean fishing boats laid ascending self-guided mines.

It is supposed to be confidential, and people or organizations with different political positions and ideologies will choose different answers for their own benefit. This option may not be known to ordinary people for decades, or even centuries.

The truth of the Cheonan incident is that the frigate Cheonan was torpedoed and sunk by a North Korean submarine. But the North Korean side denied this.

The DPRK side believes that South Korea's linking the sinking of the "Cheonan" warship to the DPRK is a "serious provocation" to the DPRK and an "action to lead the situation to a serious crisis."

On March 26, 2010, the South Korean warship Cheonan, which was patrolling between Baeknyeong Island and Daewangseongse, in the disputed waters between North and South Korea in the Yellow Sea, sank at 21:45 after an unexplained ** incident occurred at the stern, killing 46 crew members and only 58 crew members.
