What is the movie where naval ship sunk and men get eaten by sharks?

The movie you're referring to is likely "The Meg".

The film stars Jason Statham, Li Bingbing, Rainn Wilson, Ruby Rose, and Winston Chao. It follows a group of scientists and a former Naval captain working to rescue people from a submersible disabled by a 75-foot megalodon.
