How exactly do submarine captains receive their orders? Do they

Subliminal messages.

>>32200615
Located in the sail is a very long antenna with a buoy that will float to the surface.

Underwater communication is also an option.

Telepathic communication

Trained dolphins

Long wave I believe, but can't be retreived unless at periscope depth or using a bouy at periscope depth.

I am an electronic warfare submariner for the Australian navy, we recieve comms when we surface.

VLF
Very Low Frequency

Massive antenna arrays at cutler Maine and Exmouth Australia

VLF wave can penetrate water more than 100 feet deep while ELF wave can go even further beyond

I have been to the VLF array at Exmouth. Truly an amazing sight and a beautiful part of the world. Definitely go there if you ever get the chance

>>32200615
They get comms when they surface or raise a comms buoy. The could be told to surface using extremely low frequency radio waves, but those take too long to do anything but tell the sub to surface for further messages.

To note, the US actually scrapped its ELF communications systems back in the mid-2000s. Just way to expensive to continue operating (hundreds of miles of antenna wire consuming several hundred megawatts of electrical power). VLF is still used as described (basically just sending short messages that inform the sub that a new message is available, at which point they pop a buoy), but it only works to a depth of about 20 fathoms.

They make whale noises

They wait in sealanes used by bottled messages

They decommissioned the most obsolete system. Highly unlikely they moved away from ELF.

>>32200928
Yeah.
Had to do a 'piling inspection' of the fuel wharf.
Great dive site, even better than the reef on the other side of the hill

>>32201410
Old is not the same as obsolete
New is not the opposite of obsolete

>>32201996
I tried to go diving there but the AFP guys wouldn't let us in. Apparently a diving company in town has the rights to take people diving there. If I recall correctly it was voted one of the best dive spots in the world a few years back.

>>32200628
Government actually tried this. Sending clandestine orders to submarines was one of the driving forces behind the early ESP research programs. It went as far as to publish falsified results once they learned the research was useless and the Soviets were pursuing similar avenues. The Soviets ended up wasting like a decade of some poor research team's time.

>>32201270
Some of the antennas were in Northern WI, they look like 4-6 foot tall telephone poles set up in a big oval

I thought they just banged on the inside of the submarine with wrenches until they suffocated?

>hundreds of miles

Not quite, the two US stations had lines that were 14-28 miles long, and took a few megawatts to run. But ELF systems are just bonkers in general. The US transmitted at 76 Hz, which has a wavelength around 4,000 km if i remembered right. Its also extremely low bandwidth, like 1 bit a minute.

So, $100 bucks? The documentary Redsh Octobersh showed the US Navy uses CIA dropped by helicopter to deliver messages.

Submarines come close to surface and pop antennas out.
Or the launch buoys that can transmit recorded massages. Recent version of buoys can work as re-translator nodes communicating with submarine via acoustic channels and with satellites via radio channel.

>>32200615
They have to surface to get them. They usually have set times when they are expected to surface to receive messages.

Plz give me an oppenheimer style reading list on all things naval. Already read Castles of Steel and Death of the U-Boats; gave me wood. Need more input on strategy and history.
