How USS Abraham Lincoln is navigating Arabian Sea with out GPS or radar

Usually, a provider blasts the sky with highly effective radar to see threats, however in “Ghost Mode,” this emission is suicide. As a substitute, the Lincoln navigates utilizing solely passive sensors, primarily the SLQ-32 digital warfare suite. This method “listens” to the radar pulses of different ships and the radio communications of civilian air visitors. By triangulating these exterior sounds, the ship builds a tactical image of the ocean round it with out ever emitting a single digital “ping” that would reveal its location to Iranian sensors.
