Dramatic footage of a sinking Royal Thai Navy warship surfaced on Twitter early Monday.
The 252-foot (76.8-meter) long corvette HTMS Sukhothai was hit with mechanical issues during severe weather while traversing the Gulf of Thailand overnight.
The Thai navy released a statement that 75 sailors were rescued, but 31 were still missing in heavy seas.
"We will keep looking," a navy spokesman told the BBC.
Thai navy said problems for the 960-ton warship began when sea water entered an exhaust pipe, leading to a complete electrical shutdown of the vessel. The ship took on too much water when the pumps started to fail and eventually sank.
"At 00.12 am of Monday, the Sukhothai tiled even further and later sank," the navy said.

... aaaand it's gone.
"This has almost never happened in our force's history, especially to a ship that is still in active use," spokesman Admiral Pogkrong Monthardpalin told the BBC.
The warship was built in the US and commissioned into the Thai navy in 1987.
