Modern surprise attacks must defeat surveillance

How does modern satellite technology affect the possibility of a Pearl Harbor-style naval surprise attack?

It makes surprise much harder, but cyber disruption, spoofing, camouflage, or disguised missile launchers could still attack the surveillance chain.

Modern surveillance does not make surprise impossible. An attacker would first need to suppress, deceive, or evade the satellite and data systems that reveal force movement. Cyberattacks and spoofed tracks could attack the sensor network, while missiles concealed in ordinary-looking container traffic could disguise the striking platform. The modern analogue therefore moves much of the contest from physical distance into information warfare and signature management.
