Navy ELF to Be Scrapped
engywook writes "National Public Radio and The Daily Press of Ashland, Wisconsin (among others, I'm sure) are reporting that the US Navy plans to scrap the Extremely Low Frequency (ELF) system for communication with its fleet of nuclear submarines, both in Wisconsin and Michigan. The report states that the Navy no longer feels that ELF is necessary, and that they will now rely on 12 VLF systems. The system has been in operation since October 1989. The system has been protested nearly the whole time, both as a part of a Weapon of Mass Destruction and as a potential health hazard."
Well, lets see: The VLF was designed to get around Soviet technology and communicate with our subs so the Soviets could not listen in on our coded transmissions. If VLF works (who else has an equivalent submarine fleet?) and ELF harms mammalian sea life, then scrap ELF. Besides, tuned wavelength lasers from space and aircraft can communicate (at least in shallower depths) with subs and not have to worry about spreading sound waves around the planet for all to hear and try to decode. Also, lasers can carry much more information than you can with ELF or VLF and you don't have to worry about carrier waves and such either.
Also, having been on an earlier Australian sub (Oberon class), late model Australian submarine (Colins class), British submarine and several US subs, I might be tempted to say no other nation in the world can compete with the technology in the US subs. Everything else just buzzes through the water for all to hear while the latest Seawolf class is truly stunning with amazing amounts of technology layered upon layer that slips through the water with uncanny silence. Which brings up another issue: Why does the US need such a large submarine fleet? Perhaps to counter a possible naval conflict with China over Taiwan? I believe N. Korea has a few (ancient) subs...... More tactical boats perhaps would be prudent, but....

The Navy Elf's office responded with this vitriolic press release:
...
Overcoming adversity is nothing new to Mr. Elf - he had to fight to get to the top at the North Pole, and he'll have to fight here to stay afloat at the Navy. Our team actually sees this as a golden opportunity to expose the corruption, pressure, and discrimination all the elves face daily

The news article doesn't really have any technical information on ELF, so here's the obligatory Wikipedia article.
Of course, the first haphazard search I tried came up with this.

A quick reality check here. In 2003, a "noisy" Australian deisel boat sunk two US nuclear attack subs and an aircraft carrier during joint war games. The Dutch have done the same sort of thing. On a previous occasion, an Australian sub sat underneath a US carrier, inside the CBG cordon, and followed it around for some days. At the end of the exercise it surfaced next to the carrier to the horror and amazement of all involved.
The biggest danger the US navy faces is hubris my boy. That's the real thing you have to watch out for.
I stand corrected and was unaware of these exercises. Mod parent up. :-)

In other news, Santa has eleminated all ELF positions from his North Pole outpost: "Improvements in toy-making technology and the changing requirements of Today's Santa made the ELF system no longer necessary," said the news release. A North Pole spokesman said the decision to shut down ELFs came out of an assessment concluding that improvements in technology made ELFs unnecessary.

Don't confuse me with a conspiracy theorist when I say there's absolutely no reason to conclude the technology is being scraped.
Years ago the military was highly interested in non-lethal weapons that were based on a wide number of bizarre technologies including wretched smells, sonic weapons (that would make you crap your pants, or knock someone over like a 'rubber mattress hit them'), electomagnetic frequences (that cause nausea, sleepiness) and all kinds of other reality-weirder-then-fiction technologies.
Then one day seemingly in the midst of much progress they just dropped the whole thing--the budget went poof.
Since then many of the technologies have been witnessed and it's not really too hard to find info about it on the web.
I picked an example that was more over-the-top sounding then neccesary, however my point is the military's perogative is to keep their cards hidden and have the upper hand. I wish there was a way to say that more matter of factly and still drive in that point.
Stop invalid scientific research. Ask your local scientists to feed their lab rats with a phytoestrogen-free chow.
The Navy is no longer interrested in nuking the whales, they feel that confusing the hell out of them provides for hours of humour. In canada we feel different. Our submarines let the water in so we can speak to them directly :D Much more natural don't you think?

Go canucks, habs, and sens!
A lot of classic conspiracy theories revolve around ELF and VLF.
The basic recurring premise ranges anywhere from a single person to an entire town (Eugene, OR) being bombarded with V/ELF and studying the effects. The results are hardly "mass-destructive", but rather annoying: nosebleeds, headaches, premature arthritis, sore throats, unexplainable bruised, etc. Supposedly, a US official working in the US Embassy in Moscow contracted a fatal rare blood disease, and hidden V/ELF transmitter was found hidden in the walls, aiming right for his desk.
The theories allege the military and intelligence agencies were interested to see if purposefully exposing subjects would be effective as a form on mind control. I don't mean mind control in the literal sense where someone says "Go kill your neighbor" and the subject says ok and snaps to it. More like putting someone's mental state into disarray, hoping in the confusion the person would be more susceptible to suggestions and persuasive tactics.
These "experiments" flat out don't work. There's no science to back it up. But the point is someone with authority believed they could work and spent a lot of taxpayer money trying. And that's the real shame.
Please take this with a grain of salt. There's no need to go into a huge exposition trying to debunk these stories. You save it. I'm just repeating these unsubstantiated tidbits. Reports like these fueled many an X-Files episode. The producers/writers didn't come up with these things out of thin air. They're interesting to read. Not to "find out what happened", but to get an insight into the background stories X-Files sometimes use.

no, no need no worry this is about an unimportant thing in a for away place called real world.
I don't know much about the particulars of what happened in those war games, but diesel and nuclear subs are very different. When operating, diesel subs are much more noisy than nuclear subs. However, diesel subs can turn off their engine and run completely silent. On the other hand, a nuclear reactor is always on. If you're trying to avoid detection, it's much better to be in a diesel sub.
It is still impressive that two US attack subs were sunk, but this isn't because US technology is behind. It's because an older technology has a single advantage (the ability to run noiseless for short periods of time) that can be exploited in close quarters to great advantage.

For all that story tells us, the US might have sunk 30 ships. I'm not trying to insult Australians here, I'm just saying that article is REALLY vague.

A different kind of ELF hazard. From here.
B.2.2 Extremely Low Frequency Biological/Ecological Monitoring and Interference Mitigation
The ELF ecological monitoring program is an independent evaluation of the possible hazards ELF RF transmissions may have on the environment. Sampling and gathering of data was completed at the end of FY93 with review and comments on the resultant data by the National Academy of Sciences expected during FY96. The ELF interference mitigation efforts fund the procurement and maintenance of devices used to ground electrical voltages induced in long metal inductors (e.g., wire fences, cable lines) in areas adjacent to the Wisconsin and Michigan ELF radio transmitters.
Come on nerds, someone write this up.

ELF, 30-3000 Hz VLF, 3-30 kHz Oh I'm sorry did all of you overlook the fact that the /entire/ country of USA, and most of the rest of the world is /dependant/ upon 50, 60 and *enter your countries standard here* hertz frequencies?
They are emitted daily from antennas in your street or above your street, in and around your house completely covering your family like a big fudging faraday cage!!
The earth terminals which save your life /and/ rid the household of static electricity sure as hell look like a mighty fine dipole to me!
Especially when you multiply it by, oh, every house in the world with electricity.
Lets take a look at a rather interesting report:
http://www.freep.com/news/statewire/sw104732_20040 926.htm/
"
CONTROVERSY: A federal judge in Wisconsin halted construction of the system in 1984, saying more environmental and health studies were needed. A federal appeals court in Chicago overturned that decision. The Navy said it spent more than $25 million to study the impact of ELF's electromagnetic fields, which were described as similar in nature and strength to those produced by power distribution lines.
POLITICS: Within years after ELF was built, Wisconsin politicians, including U.S. Sens. Herb Kohl and Russ Feingold and the congressman who represented the Clam Lake area, Rep. Dave Obey, called for its closure."
THat's all well and good in a "contained" environment, i.e. brown water operations next to the diesel sub bases and/or chokepoints. In blue water ops, when a carrier group averages 20+ knots for extended periods, if not continously, it is a different ball game.
Even with the new classes of submarines, you would end up using diesel subs as intelligent mines; almost stationary in relation to the target, which must practically run over them to do itself harm.

I did not realize that. Personally, I'm glad to hear the armed forces are becoming more tolerant.
After attending militar excersises with US personell, I can confrim this. In one excercise, our home guard kicked the ass of the USMC. I find that incredible, but not if you analyse the mentality of the USMC. They fly in on choppers, equipped with the baddest and coolest in military technology. They are big fellas with kick-ass war faces. Then their chopper lands and they jump out. And fall into 2 meters of fine grained snow. The the Norway Home Guard (Maybe even that cute girl on the picture) come loafing around on their cheap-ass skis (The skis are called "NATOboards", guess why. See them here: picture). The USMCs are thouroghly stuck in the snow, not able to reach their equipment, and all of the team are killed by headshots, according to MILES.
Also, the american forces are a bit naïve. On another excercise, navy SEALs were to rescue 2 prisoners from a building on the top of a hill. They left a bunch of equipment behind, as the excercise did not allow for CS gas to be used. The Norwegians responded by having only a couple of gunmen in the building, while digging the others into the ground at the foot of the hill. As the SEALs passed the soldiers by 50 meters, the ones in the building pounded the SEALs with CS, and the dig-in soldiers ran up and shot the confused SEALs in the back. The SEALs complained that they iddin't excpect CS to be use and had no ABC equipment with them. Their colonel apparently gave them a chewing out, becaus they were so incredibly naïve to think that every force in the world would obey the rules...
Diesel boats are extremely quiet when running from their battery stack, and they are a major tactical threat to even the most modern Navy.
Hubris indeed. It's easy to get your ass kicked by a foe you don't respect.

For a moment I thought the navy had their own executable and linking format. Must be too early in the morning for me !

Nonsense. The us navy is painfully aware of the dangers posed by quiet -- be they ultra quieted SEAWOLF class nukes, DE's (diesel electrics) or the new generation of european AIP (Air Independant Propulsion) boats.
Oh, and there were 3 DE's, not one. Oh, and your "noisy" comment: a DE is only noisy while it's snorkeling. When she's on battery propulsion, she's as quieter than a nuke, generally speaking. Trust me, nobody in the US Navy thinks DEs are rattle buckets.
And the Navy knows, having been taught this lesson by its own submarine fleet, that a quiet boat is a fearsome, almost invincible enemy. The purpose of the excercise was to help the Navy figure out how to take out a DE operating in the littorals. It ain't easy.
The one and only reason the Collins's survived is because the engagement orders required the CVBG to enter into her backyard, where the DE's advantages were best put to use.
No one was surprised, only highly irritated.
The biggest danger to the navy is littoral DE and AIP submarine proliferation, mines, and high speed small boats packed with explosives, manned by the willing-to-die. The biggest danger to the navy isn't hubris, and frankly, i find the implication offensive.

That's the only reason the Navy will give up on a technology. After six years in boats, two years in training prior to, I came away very impressed with the ongoing developments of tech as an instrument of war. The Soviets could not beat us in that arena, even with Walker trying to make money off what he knew... The only other venue for tech development (outside that for warfighting capability) that has shown in recent history such rapid progress has been the race for the moon in the sixties.. Remember, the US interstate highway system was modelled after Hitler's auotobahn system - designed for high speed transport of war materiel and troops...

"These are the stories from a guy in the Telemark Battalion, when they were on excercise. Anyhoo, it is more a story on how the US soldiers ignored obvious climate changes, and that is why they train here to start with,"
You hit the nail on the head there. Any military, be it US, Hungary, Britain, Zibabwe, wherever, must train its soldiers to kill and think they can beat anyone - otherwise they will almost always loose. That is also known as hubris. This must be tempered with the ability to think.
For example, the local gun range is on a national guard base. A few times a year the Army uses it for "training". One of thier special forces (I don't know which - they will not say and I don't care enough to actually dig and see) trains there. It is the last few days of their training - they play war games mostly. On one of thier times occupying the base there was a scheduled shoot. We had to move it and needed some material (signup list for the shoot IIRC) from our club house. The general in charge allowed us access for the material as long as she escorted us. She and my father got to talking about training/coaching markmanship and he asked about what they do there in training (we had always wondered as there was usually quite a bit of damage to the facilities and odd structures built in the woods). She explained about the war games and other fairly mundane training excercises they did. She then told him that on the last night they did something "special". After all the training and convincing that they were the Greates Thing on the Planet they were given a rude awakening. The recruits were told to guard the barraks. During the night a group of Rangers crossed over the fence and forcefully captured each and every one of the recruits. It was supposedly a humbling experience (I know that it would be for me).
I would bet that the situation you describe was something similar. If they had performed flawlessly that would have been great. I bet that the people in charge got thier second best option - total routing and humiliation.
" and rely only on their egos."
That is *exactly* what they try and root out. No commander in any major country is stupid - all know that is bad and will loose wars. Do you really think that the US military is that stupid? I bet your country sends soldiers on training missions they know they will loose for exactly the same reason - militaries have been doing that for thousands of years.

That reminds me of the time when some Finnish units went to Norway for joint exercises with Norwegians and Americans. Exercise was about warfare in arctic conditions. Well, as it happened, only the Finns and the Norwegians carried out the combat-training as intented. The American troops just stayed in their tents and tried to stay alive.

SLASHDOT: news for people who can't concentrate on work or have no life at all and got tired of yelling back at the TV.
As for the story with the CS - I guess I don't see the point of that. If the purpose of the training is to operate without CS, then why blame the soldiers for doing the exercise as they were asked to? Ok, in real-life you don't know whether the other side would use CS, but then in real-life you wouldn't be told it was an exercise without CS. So is that really important?
Looking at the performance of the US military you can't really claim that they don't know how to fight. Quite apparently they are up to the job when it comes to real life. Their main deficits (as I see it) is in policing - they perform well in conquering a place, but poorly in holding it. That's sufficient if the main purpose of your military is defence, but it's a disadvantage if you want to conquer/bring peace/build an empire (pick according to political view).
Using CS when it was decided that the exercise wouldn't deal with that component.... hmm... If that's the mentality you're working with, why did you even use blanks in your weapons? Use live ammo, they'd never expect that! After all, not every force in the world would obey the rules... plus you'd totally win! There is a huge separation between being naive and operating within the parameters of an exercise. Exercise conditions are decided upon to protect the safety of those involved and to focus on certain objectives. For whatever reason your 'Home Guard' went against the parameters that had been decided on and used CS on people they *knew* didn't have equipment.
If I have ELF support compiled into my kernel does this mean I have to pull it out and recompile?
As a last resort, we could look at the science behind ELF before we worry too much about the "damage": (1) ELF transmitters are only a megawatt or so. The ELF waves are sooo long (many thousands of miles), that a little 50 mile antenna only radiates oh, maybe 5 watts of effective radiated power. (the rest just heats up the wires). Those 5 watts get spread more-or-less evenly all around the earth. (2) Your tpical large marine creature is maybe one billionth the size of the earth, so we're down to maybe 5-billionths of a watt hitting the beast. (3) Your typical animal is an even smaller fraction of the thousand-mile ELF wavelength. So about 99.99999% of the energy incident on say a giant squid goes right through it. We're now down to 5 quadrillionths of a watt. (4) A typical nerve discharge is around a THOUSAND to a MILLION times that amount of energy, so the ELF signal is that much weaker than the thousands of nerve impluses going off right inside the squid's body every second. (5) So I would not worry too much about ELF harming anything. (6) And, oh, as other have mentioned, the energy from power lines is many orders of magnitude stronger than ELF (and even that is hard to pick up any distance from power lines).
Our deterrent against the Canadian threat.
That's the problem with nukes and lawyers. Both are expensive, harmful when used, and flexing them is bad for PR, but if one has them, everybody else is forced to get them too.
I've got a good story 'bout this.
There's used to be an annual NATO tank competition called the "Canadian Army Trophy".
When the M1 first came out, it caused quite a stir, as it was far faster and quieter than had been expected. But the thermal sights also gave the Yanks a huge advantage on the pop-up target range.
It seems that the motors used to raise/lower the popups were hot enough to show up on the thermal sights, and the thermal load from raising a target made the motor glow hotter before the target was fully raised and visible. Accordingly, the M1 kicked ass on the popup range, and overall swept the competition.
The following year, the Canadians (who hosted the competition) placed a large number of thermal dummy motors out on the popup range - and the M1 placed miserably. They also adjusted their own tactics to deal with the M1's strengths, and soundly defeated the Yanks.
The lesson here is that while a technological advantage can indeed give you the upper hand, such an advantage is fleeting. Properly motivated and creative soldiers can devise ways to defeat your tech anvantage and can and will hand you your ass.

Re: the USMC performance. You may not know this, but the only decent winter training ground in the entire lower 48 states is in Minnesota. We get temps reaching -40 degrees C about 5 or 6 times a year with snow depths typically around a meter or so. The local NG and Reserve units train there all year long, of course. However, it costs so much to rotate a US Army Division from its home base to Camp Ripley that they typically get up here maybe every 3-5 years at most. So far as I know, outside of our local Marine Reserve unit, no Marines get to use Camp Ripley at all.

I think the US Pacific fleet Marines train in Alaska once in a while alongside the Army Rangers and mountain troops (Is the 10th Mountain Division still active btw?). The US Atlantic fleet Marines has no handy training ground except for the annual Norway exercises. So, keep humbling them! It'll do 'em some good.
I'm also reminded of a story a Marine on Guam told me once. He said that his platoon was taken into the jungle for a three week exercise. They did pretty well until the last night. The instructors were all Vietnam vets. They told the platoon to pick one member of the platoon to act as the target. They could pick any defensive position that they wanted. The trainers guaranteed that the target would be 'killed' in hand to hand combat with no one the wiser in less than 15 minutes.
The platoon decided to literally surround the guy standing shoulder to shoulder. 5 minutes into the exercise, they found out they failed. The instructors had placed a guy in a big banyan tree overlooking the compound. It was trivial for him to drop in, 'kill' the guy, and shinny back up into the tree. The jarhead who told me the story said it was one of the most humbling and educational experiences of his life.
I referenced this link in another part of this thread, but it bears repeating. Check out the veterans' proverbs floating around the 'Net that are known as Murphy's Laws of Combat. Very illuminating. And funny in a sick, twisted sort of way.
I'm not an American either, but I worked alongside (and "fought" against them) many times - and there is unquestionably a "national character" to the US (and other nations') Army.
Keep in mind that I'm generalizing here.
The American Army is huge, has a lot of really good and impressive kit (not necessarily the best stuff, but the average iquality level is pretty good and they have a LOT of it) and undertrained.
By "undertrained" I mean that the average American soldier is very heavily specialized and is often explicitly forbidden to branch out. Each soldier has a specific job and a specific purpose.
Whereas in smaller armies like the Canadian or the Isreali, soldiers are expected to do much more and are encouraged (within certain limits) to improvise.
A quick example: let's say you are a commander, on top of a ridgeline, advancing with an armoured brigade towards an objective a few km away. On the next ridge up is a wooded area you think might be harbouring an enemy infantry position.
If you are Canadian, you will send forward your very highly trained and impressively skilled brigade recce troop. They will sneak forward, scout out the woods, and report back on what they found without the enemy (if he is there or not) ever noticing that they were there. If the enemy is in the woods, you will then quickly plan out a brilliant and innovative quick attack that takes the enemy completely by suprise (and in the flank too) eliminating the enemy with the minimum amount of own losses and ammo expenditure.
If you are American, you call up two more brigades out of your division, and the three of you pound the wooded area flat with direct fire, while divisional artillery fires in indirect support, and the Air Force adds a squadron of B52s. Once the fire mission stops, you will send a patrol of junior privates up to the matchstick pile to see if they can find any fragments of the enemy. If they don't, there was a company in there; if they do, it was at least a division.
Which technique is more effective? *shrug*
What does wind up happening though is that any time you fight the Yanks size-on-size, they Yanks typically get the short end of the stick. The counter-argument is that the Yanks NEVER fight size-on-size, so it doesn't matter.
I will say this though - any time we schooled some Yanks, they were typically VERY enthusiastic about how we did it, and wanted to learn. They weren't stupid or unprofessional, just undertrained and overmanaged.

The other cool thing about a D.E. sub is that you can surface it and put a lantern at the top point of the sub.
Then have all the crew start singing "louie louie," rather drunkenly.
After the nuke leaves cause it thinks you're a fishing vessel, you hold a mock pirate trial and dump an idiotic loudmouth onto a passing fishing vessel, piggyback between the screws of an oil tanker and blow up the dummy ship in the harbor.

That would be pretty hard to do. With watch-to-watch pub and crypto turnover, TPI (Two-Person Integrity), and other safeguards, ti would be hard to steal the crypto. Even if you're the WatchSup, you CAN get your own padlock open, but the second person has to do so or comply. After that, the second person would have to turn a blind eye long enough for the trusted spy to somehow copy the strips or cards or sheets.
Even so, once the compromise is discovered, the entire fleet would cease using the crypto, except for maybe a handful of decoys in the compromised area who'd continue feeding disinformation into the system to delay knowledged of the compromise. However, once the genereal oparea is told to cease using it, the compromise effectively is known. Even if the reported compromise is covered by HQ just self-censoring what it sends over the encrypted circuits, an enemy or defector using the crypto cannot use it beyond an predetermined, scheduled time block. Just as newsfeeds expire, so do crypto periods.
While it would be possible to steal crypto for a given period, they physical evidence (hard plastic, clear or dark, in clumps or packages that will be obviously missed if moved or remove), you generally cannot steal it now and use it later, for timeshifting (not exactly like TIVO, et al) would elminate the usefulness. Meaning: Crypto stolen for period 0600-1200 or whatever used AFTER that period simply won't work. They cyphers embedded in the transmission stream would ensure that improperly-embedded responses trigger a compromise alert.
Read some books out there (communications pubs, crypto books, communications security methods, and your imagination. It's not necessary to bribe anyone for information if you can reassemble or combine peripheral evidence. Read and re-read. The process I describe is not in itself super sensitve. The crypto IS. The physical protection of it IS. Stealing it is pointless, except to invite jail time.

As for knowing where the sub is, subs have OpAreas just like surface ships do. The satellites would signal to as narrow an areas as possible, likely in bursts, over a short duration, and at random intervals so as to deny detection of the boat's locality if a trawler or signal-soaking craft is in the area by chance. Alternatively, the sub can release a trailing wire antena for maybe 2 miles, and collect instructions or messages. In a worst case, they could cut the cable and go deep and quiet in a threatening situation.
I would imagine that remote sensors or torpedo-like vehicles slip from the hull, trail or shadow the boat, and send and receive signals from a non-disclosing distance. It's what IIII would do if I had the valuable boats, the money, and the imagination I have now. We have predtors for ground crews, so why not remote off-board vehicles for expensive subs that might have to sit or hover (to keep sand out of certain cooling intakes) for extended periods, periodically degaussing (or doing other things to/for) their hull signature. A ROV would SIGNIFICANTLY enhance the privacy, security, safety, and stealth of ANY navy's subs, for a smaller price than innumerable anechoic tiling and rubber-mounting deck rafts.

So I guess these countries don't actually have nukes of their own? I seem to remember the only country that once had nuclear arms and dismantled and destroyed all of them was South Africa. They also dismantled them of their own accord, as no one even knew they had them until after they told us they were all gone.
I guess it's not important to you that there are actually 8 nations that are known to have nuclear weapons. It's probably equally unimportant that all these nations actually realize what will happen to them if they use them on someone. Nuclear weapons in the hands of sane people are not a military threat, but political leverage.

I'm not in the military (now or ever), but a friend in the Canadian forces tells me this can be so rigid that a mechanic for one type of vehicle can not, does not, and will not work on another type of vehicle.
So much so that in one operational theatre an humvee could not be made to go because no humvee specific mechanics were present (or they only had a humvee mechanic, I can't remember which). The underlying problem was something common to all forms of internal combustion engine, but the only US mechanic present was not allowed/capable of applying the fix to a different kind of vehicle.
My friend had the vehicle moving in under 2 minutes.
It's been my understanding this undertraining/overspecialization within the US forces can sometimes lead to a bunch of people standing around with no idea what to do next.
Scary stuff.
