The Royal Thai Navy said in a statement on the 19th that the warship Sukhothai of the Thai Navy sank in the early morning of the 19th after encountering strong waves in the Gulf of Thailand on the evening of the 18th. Of the 106 people on board, 75 were rescued, and the rest 31 crew members are missing. The search and rescue work is still in progress. According to a report by the Bangkok Post of Thailand on the 19th, Thai navy spokesman Bogong Montapalin said that the Sukhothai had encountered strong winds during her voyage on the evening of the 18th local time. The waves caused by the strong wind rushed into the cabin, causing the ship's engine to malfunction. After the ship lost its power and power, the ship's drainage system was unable to discharge the sea water that continued to pour in. The ship's roll became more and more serious, and finally sank at about 0:12 local time on the 19th, about 20 nautical miles from the land. The Thai navy sent two helicopters and three warships to the rescue after receiving the distress signal. The rescue force carried portable drainage equipment to help the leaning Suketai drain water, but failed because of high winds and strong waves. It is reported that there were 106 officers and soldiers on board the Suketai when it was in danger. 75 officers and soldiers were successfully rescued by the rescue ship on the scene, and at least 3 of the rescued were "seriously injured". In addition, 31 soldiers remain unaccounted for. The Associated Press reported that as of noon on the 19th local time, the wind and waves in the sea area had weakened, and the Thai navy was still carrying out search and rescue, covering an area of about 16 square kilometers. According to the Bangkok Post, the 31 soldiers who are still missing should all be wearing life jackets and may be floating in the nearby waters. The spokesman of the Thai navy said that because of the heavy wind and waves on the sea, it was difficult for rescuers to see the drowning people by boat, and they had to rely on helicopters to find rescue targets in the air. A rescued sailor of the Suketai said that when the ship sank at night, the sea was very stormy and the waves were as high as 3 meters, which affected the rescue process. At that time, he was rescued after floating in the sea for 3 hours in his life jacket. Bashu Prefecture near the sinking site of the warship is located in the south of Thailand, adjacent to the Gulf of Thailand, and there are many ships coming and going. The Gulf of Thailand belongs to the marginal sea of the Western Pacific Ocean. To the west of the South China Sea, it is relatively calm most of the time. However, during the period from November to February of the next year, the Gulf of Thailand is vulnerable to ocean currents and cold and warm air currents, resulting in severe weather such as storms and rainstorms, which can cause strong waves and pose a threat to ship safety. Meteorological information shows that Thailand has been experiencing extreme weather recently. On the one hand, the lowest temperature in the year occurred in the north central part of Thailand, while in the southern part of Thailand, including around the Gulf of Thailand, storms and floods continued. Recently, the maritime department also issued a warning, asking local ships to stay in the port and not go to sea. At the end of November, a reporter from the Global Times once took a speedboat in the waters of Bashu Prefecture and drove 10 kilometers off the coast, where he encountered a violent storm. The boat rolled up and down on the sea like a roller coaster. It is one of the seven frigates in Thailand. It is understood that the Thai navy has a total of seven frigates, and the Suketai is one of them. It is also the second of Thailand's two Latanakosin class frigates
