The tanker was broadcasting its position. That's how we have this nice visualization. I don't understand why you are talking about active systems. They should just have listened to AIS messages.

Likewise also don't understand why the article goes on and on about more clever ways the collision avoidance system could be programed. No collision avoidance system can help you if the operators of the stealthy war-machine drop the ball.

Oh, I wasn't aware you can receive other ship's AIS position updates while your own system wasn't active.

Even in that case, it's the same as the passive sonar example I illustrated: the ship is there and you can see it, but they didn't avoid it anyway. Failure of communication.
