We would have a present code book, rotating daily, with the decode of character groups.
Then we would establish a single HF frequency for the battle group and keep all silent until there was a flash message to be delivered.
Then, the ship with the flash traffic would send the small set of character codes VIA MORSE CODE to the battle group with a transmission lasting no more than 30 seconds. There would be no acknowledgement.
Emcon. Hack proof. Effective.
There are all sorts of contingencies worked out in Naval communications. Lots of them.
This article talks of one that made the news because it's so cute.
There’s just nothing dumb about this, cause anything digital can be hacked or monitored.
American Indians?
A thirty aircraft recovery at night w/no radio comms, no electronic navaid emissions from the carrier were commonplace thirty years ago. I hope they still train that way.
Digital messages sent via low powerlaser would work. Very narrow beam, undetectable more than a few hundred meters.
They could go back to Spartan message rods.
They think it’s cute only because they won’t have any way to hack in.
Will our Navy go back to semaphores, with the vulnerability being that they have to remain in visual range of each other?

Cool history, thank you!
Encryption algorithms *might* be subject to attack or decryption... So why not go back to something immune to that: one time pads filled with random noise. These could be distributed to fleet units by courier prior to embarking, or via helo if a unit joined up. A single DVD could contain gigabytes of random numbers for the simple transposition cypher. There’s no algorithm or equation to be broken. No frequency analysis is possible.
“Then, the ship with the flash traffic would send the small set of character codes VIA MORSE CODE to the battle group with a transmission lasting no more than 30 seconds.”
I have been told the military no longer trains Morse code. I believe that is true but don’t know it for a fact.
MI Ping
Aldis lamps and morse code, semaphore, preset code words.
Often, simpler is better.
Somewhere along my military career, I remember being told that the safest way to send a message was by courier.
Bean bags because of treasonous self absorbed folks like Hillary Clinton, Sid Blumenthal, JOHN Brennan, James Clapper, Peter Sztrok, and most of the FIB.
IIRC, read somewhere that backwards countries would be more likely to survive nuclear armageddon, because their technology would still work.
Hand water pumps, e.g.
Last I heard they are still using signal lights, semaphore, and signal flags as well. Still have to be able to communicate in Emission Controls or if the radio goes out.
“VIA MORSE CODE”
Fists are almost like fingerprints.
By the mid 70’s the good US military CW ops were Coast Guard. Globally, probably the Soviets.
