Dave, I am sure you would not be surprised just how many visitors to Model Boating exhibitions, or just by the Pond, are/were serving Sailors on or from Naval vessels.......or even associated personal from shoreside
So standing back & observing those viewing the detail on the models can sometimes tell a story
Those castings look sharp
It is a little difficult to comprehend that each of those white tubes can shoot, position and project a full size invisible 3D image representation of the real vessel ...

!!...it appears to be a generation [or 2] further away from Heat-Seeking or Chaff Cloud technology]
Yes, invisible to all except an incoming Missile of the Foe
