Precisely.

This is the objective of the adversary in a conflict with respect to information and systems security. It doesn't matter if they can control a system, if they can make it less reliable it's still a win (but not as good). If they can get it to feed out false or misleading information to their opponent, it's a win (hacked a radar, can you show an extra blip on the screen or cause them to sometimes shift position and reduce the confidence of the operator?).

I have been thinking the recent Navy navigation related crashes are related to enemies tampering with systems. They are testing live how weak a windows based fighting ship is.

From what I understood the recent Navy collisions are caused by under-staffing => sailors having to work too long days => sailors literally falling asleep at their posts / seeing things that aren't there / not seeing things that are there

They seem to work twelve on, twelve off, with requiring that some of their personal time being used to maintain physical fitness, so does seem like a disaster waiting to happen.

There is zero evidence of enemy tampering in recent Navy ship collisions / allisions. It was simple incompetence and bad luck. There's really no way to tamper with shipboard surface radars, binoculars, horns, and VHF radios. As long as that equipment is working correctly all collisions can be avoided.

I did not specify an exact scenario because that was not the point I was trying to make (it was actually meant mostly as a joke, no?). If they already have to fight with so many bugs, disabling it will be just as hard on the one hand, and the operators already have top live with disabling issues in the non-invaded system, as one comment posted here said, they didn't even notice the invasion because it didn't feel different from normal operation :-)

Or just being a passive viewer of what the system is managing
