Ok, sub guys, we used to have two ELF stations, to broadcast a code group a submerged sub could receive, that meant, "Come to antennae depth for updated instructions right away!" or words to that effect.

We don't have an ELF station anymore.

So how would we get the subs in if stuff goes down?

SME comments welcome.

You can't transmit a signal at a low enough frequency to reach a submerged sub. You need miles of dipole antennae. 4 Hz.

Four.

You know why you don't hear anything about telepathy anymore? Because it's reached the stage of being deployable for mission-critical applications. Shhhhh. I washed out of the program, but you're not supposed to know. You're welcome.

Used to be a certain split of ELF and VLF coverage was required when covering an alert target package (the requirement existed because everyone hated ELF).  Now ELF is gone.   Couple different useful antennas for VLF which work well at alert coverage speed/depths and offer a lot of flexibility.  Spend a lot of time also covering HF voice (TACAMO) which sucked, mostly because it took extra manpower and was spotty depending on where you were and the typical HF reasons.

ELF was a pain since it was fairly directional on the floating wire with only the one station.  Doing a turn required coordinating speed and the time within a tight window when you'd throw the rudder over to be able to stay within the coverage requirements.  Boomer turns are slow.

ELF had a ridiculously slow baud rate.  You'd spend a long time getting a code that said either "A-Ok" or "Come shallow NOW!"

Not sure why exactly ELF was canned, but I'd take VLF all day every day for a laundry list of reasons.

They just have a phone line that trails behind them that is attached to a big spool.

But it's a party line, so if you get to talk to your girl, know that the guys in the torpedo room are listening in and trying not to laugh.

You were supposed to keep fucking with me mercilessly until pg 2 but thank you. This is what I'm after.

So, it's sort of assumed that any event will be proceeded by a gradual escalation and the subs will be ordered to patrol at a depth where they can receive real time updates? What happens in the event the shit is an afternoon delight? They find out at the next scheduled surfacing and everyone's either excited or silent on the radio?

I was there. Maybe they obfuscated in my radio prop courses for National Security reasons, but that seems like it would have some cascade effect on math for other shit. 60' is about right. I saw that, hence the Q. You can SEE a sub on the ol' Mk1 EB, if it's only sixty feet down, from the air in like 2/3 of the ocean if the waves are reasonable, and nearly everywhere at 30'.

You can see WHALES at that depth, ffs.

I'd like to see the white paper on this spooled aerial radio broadcasting without an earth at sufficient power to reach more than 50-75 below  the ocean surface.

Different coverage requirements depending on whether you were alert, mod-alert, or non-alert.  An alert boat is monitoring 24/7.  Any sub in general has to copy the broadcast couple times a day.  At a certain def-con, boats may automatically assume a different alert posture and sortie.  Operating procedures said a launch order without escalating def-cons is dubious.  There's a lot of traffic that needs to go over the wire so it's prioritized and sent over a clock schedule.  Op orders, intel, weather, admin, news/sports, family stuff.  Was typical that the window closed before family stuff got uploaded.

We used to get 10 forms to give to family with 50 blank spaces on them for family grams (name and rank got subtracted out of the 50).  The opposite crew screened and uploaded them, and the XO (and/or COB) on the ship screened them before you got it in hand.  You were doing well to get 6 or 7 in a 10 week patrol.

I got pulled aside one day and asked "who is Missy?" by the XO.  Missy was my parent's lab.  The message in question included "Missy disappeared 5 days.  Came home stinking of diesel and whiskey."  She'd fallen into an oil drain pit in someone's barn.  Anything sexy would get the name redacted and posted outside crews mess.  I remember someone's wife sent something about missing Monday Night Football that was amazingly phrased and got the whole crew worked up. She was a gifted poet.

And like I said, we had orders to cover scheduled HF voice transmissions from time to time as part of routine business.  When the def-con ratcheted up, those bands would go in availability.  "alfa velvita knuckle underwear sphincter spider mucous ringworm.  I repeat alfa velvita...." with a paper shredder running in the background, and the signal fading in and out.  Picture DX from turbo prop.
