I picked up a copy of 'Engineers At Work: Attack Submarine' in a charity shop back in Tenby on the weekend. A bargain at £1.50 but also good fodder for my latest tentative metaphor. We'll skip past 'Detecting the Prey' and 'Weaponry' and go straight to the chapter on communications.
We're told that "communicating with a submarine on the surface in peacetime is easy, but talking to a submerged submarine in wartime is much more difficult". So communications engineers solved the problem in several different ways for many different scenarios.
And built in the tools for a wide variety of different communications channels into the submarines mainframe.
The metaphor? Something about the choosing the right channel for the right scenario, or at least having a healthy choice of channels, and frequencies, and that. You know.
