Searching for a submarine is like searching for a needle in a haystack. The faster the sub moves, the larger her noise signature, and therefore the larger a needle she is, making her that much easier to find. If we assume that a submarine stopped dead in the water has to be passed right over head to be heard (Needle), in a 100 square kilometers of ocean (haystack), it will take either a lot of time, or a lot of assets, before statisticaly you pass over the sub. If she is moving and creating a 2 square kilometer sound signature around her, she is statistically now much easier to find (much larger needle).

But then, I'm only a cyber-skipper. Maybe the BTDTs know somethign I don't.
