    It is simple, it is not easy.

    ‘Take a picture of the entire ocean and look for ships’ is simple, but executing that plan is not.

    It requires hundreds of millions of dollars of reconnaissance satellites, and an entire branch of personnel to operate and digest the information.

    This is why the US operates carrier battle groups instead of just sailing their carriers everywhere with a small escort. They can’t hide, but they can pack enough offensive and defensive power into a tiny area to make most attacks infeasible.

    Anyways, there’s a reason submarines exist

    True, and even they’re vulnerable when they surface (if they’re moving), the v-shaped wake is also very detectable from space where satellites can detect wave heights within 3cm. It’s not easy for humans to find, but with billions of dollars to spend on computers, these kinds of things are very much within the reach of sovereign nations.
