Why better sensors still leave uncertainty at sea

Will new sensor technology make the naval domain transparent?

Complete visibility is considered unlikely in the foreseeable future. Sensors face countermeasures, and an ocean model precise enough to expose every disturbance remains a distant prospect.

Land warfare has not become fully transparent: clouds limit observation from satellites, woods conceal troops from drones, and thermal sensors can be masked. Better sensors give their targets reasons to develop new countermeasures. Camouflage also complicates visual identification, so direct sight is not a universal solution. At sea, detecting every disturbance would require a much more accurate understanding of how the oceans normally behave. Complete naval transparency is therefore treated as a distant prospect, even as surveillance improves.
