Seeking the title of an American sci-fi film

The plot was like this. A US nuclear submarine mysteriously crashed at the bottom of the sea. The authorities then sent an investigation team composed of scientists and special forces to investigate the cause of the accident. Later, the plot was about the scientists and the special forces having a conflict in their cooperation. As a result, the special forces were completely wiped out. Finally, a member of the scientists wore a special diving suit (similar to a spacesuit) and risked his life to dive deep into the sea. At the last moment of his life, he was rescued by an alien and taken to an alien spacecraft. Then, he surfaced with the alien spacecraft. This movie was broadcasted on Shanghai TV Station 2 (the predecessor of Shanghai Lifestyle Channel) seven or eight years ago. It was a classic but I forgot the title now. I can't search for this movie on the Internet.
