The familiar radio exchange in which a warship orders a lighthouse to change course has no credible historical basis. Different versions assign the ship to different navies and usually require an entire bridge team to ignore charts, position data, and multiple navigation beacons. A vessel would also have to be dramatically off course before the confrontation could occur as told. The story works as a joke about authority and situational awareness, but it should not be cited as a real naval incident.

Why the warship and lighthouse radio story is a joke
The warship ordering a lighthouse to change course is naval folklore whose many variants collapse under basic navigation and source checks.
