the ELF stuff we used to talk to subs is real neato.
but it says we've disassembled them? what do we use now?
>>
DWARF. It excels at going deep but cannot coexist with ELF.
>>
>>64345355
VLF and satellite.

It was a lot more useful during the Cold War when there was a small (but non zero) chance that we'd have to communicate with a submerged submarine while nukes were in the air. The world, and its communication systems, have changed significantly since then, and it's not really necessary anymore. Remember that ELF's bandwidth was too low to communicate significant amounts of information, and that it's main use was to tell a submarine to come up to periscope depth to copy traffic at a useful bandwidth. The analogy that the time was that it was a pager. I expect that most of /k/ these days won't understand that, but you can Google it. If the message could wait six hours then it waited, because you came up to PD every six hours to copy traffic anyway. If the message couldn't wait six hours, that meant that nukes were in the air and ELF was appropriate for letting a particular boomer know to launch its own payload, please and thank you.

These days (and back in those days for that matter, now that all of the cards are on the table) there's very little chance of a surprise nuclear exchange. You could make the argument that we should retain that capability, but you could also make the argument that that capability was very expensive and would probably never be needed.
>t. did a tour on a boomer back in the elf days

thanks for the post boomer boomer

>>64345627
You didn''t answer his question.
>>
>>64345355
The general consensus is there's an acoustic system that can rouse deep running subs who aren't otherwise receiving communication. I've seen references to VECTOR, REBOUND, and DIETY covering various experimental and possibly operational systems.

>>64345781
He answered it quite clearly. Read it again
>>
>>64345781
nothing, because it is no longer necessary.

Did it get a knife-ear mascot like NASA did for their ELF?
>>
>>64345355
DTWA on an E-6

>>64346368
>name it ELF
>don't even use Titania as the emblem mascot
Shameful.

>>64346498
His name is starfire and you should really be nicer to him.

I thought the design was familiar
fuck trolls, love wolves, howl at the moon

You have no right to be this witty on this shithole of a site, delete this.

As >>64345488 said, VLF works from specifically-equipped aircraft, albeit at shorter (but classified) ranges, and subs come up to check their e-mail periodically using satellites, which will get even easier if they start equipping them with StarLink/StarShield antennas. And as >>64346090 suggests, there MIGHT be some sort of long-range acoustic signaling; like ELF, all it really has to do is transmit 3-5 bytes of data, or theoretically just one loud burst on a very specific frequency in order to get everybody's attention so that they come up right away to talk to a satellite.

what about like neutrino comms
>>
>>64350251
Have you tried modulation a nutrino carrier? I'll bet you haven't.
