While I agree that all the ships will have scanning of one sort or another, I expect that some ships will be much better at scanning so that you need other people in other ships. The exploration ships have scanning as their function, much like a mining ship has a mining laser and tractor beam for it's function. Other ships can shoot rocks and carry a tractor beam to haul them in, but the mining ships are specialized to that. So, Beta, LX, 315p, Freelancer DUR, Aquila, 600i Explorer and Carrack have to be good at scanning for exploration, whether it's a new jumppoint you are looking for or titanium ore. The other class is the scanning ships like the Cyclone TR, Tracker, Terrapin, Reliant Sen, possibly the Herald and the Endeavor with telescope array. I expect all those ships to have significant power and range capability over something like a Sabre or a Hull C.
