Battleship sounds like a good analogy, but is very different because you don't have other options to "secure your ship" besides obscurity. If you had other options, let's say a sonar or moving your ship, they would definitely be used along with obscurity.
Besides, the time to scan the whole board is too time consuming in a battleship game, but scanning the whole internet on the other hand only take a few minutes[1]
