The 'Hunter Killer' real story is about a complex military operation. In real life, submarines are highly advanced and secretive weapons platforms. The story might draw inspiration from actual naval strategies and events. For example, the idea of a submarine infiltrating enemy - held waters to gather intelligence or carry out a strike. It also reflects the intense training and skills of the submarine crews who have to operate in a very challenging and dangerous environment.
Well, Hunter Killer isn't rooted in reality. It's a made-up tale designed to thrill and engage the audience. There's no factual event or person behind it that it's based on.
