Navy ELF to Be Scrapped 454

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....

    A quick reality check here. In 2003, a "noisy" Australian deisel boat sunk two US nuclear attack subs [64.233.161.104] 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 [reference.com] my boy. That's the real thing you have to watch out for.

    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.

    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.

    A different kind of ELF hazard. From here. [fas.org]

    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.

    Who says these "experiments" were ever tried? The ELF/VLF systems have significant communication uses; the money was spent on them for that purpose, not for some hypothetical, very possibly never conducted, "experiment".

    After attending militar excersises with US personell, I can confrim this. In one excercise, our home guard [www.mil.no] 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 [hvungdom.net]). 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...

    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...

    There's been concern about that too from people who live in proximity to National Grid 400kV transmission lines. There's still no real scientific evidence that it causes a health hazard (although when we lived around 1/2 a mile from one our garage flourescent lights would always dimly glow when not turned on, and on a damp evening you could hear the 50hz buzz).

    Apparently, you've never been on a German class 214 submarine [globalsecurity.org], then. (Germany has a long tradition of building excellent submarines ever since World War 1.) They're built by HDW [www.hdw.de] in Kiel with a diesel-electric drive and a fuel cell unit for long-term underwater operation. The fuel cell drive emits very little noise as well as no significant heat at all. For more information, see the section on the class 212 and 214 projects [naval-technology.com] at naval-technology.com; as fas as non-nuclear subs are concerned, they're the most advanced boats on the planet as of now, and they're becoming an export hit, too.

    Well obviously they would be the first against the wall. But don't forget they require a truely massive amount of power and that the power grids get damaged in war. There is only so much oil you can store to run the backup generators....

    Its's more likely they run on the principle of if transmitting then all is well. What might happen if they had stopped transmitting is scary....

    Also remember that the data rate is very very slow. They probably only transmit a command to come towards the surface and initiate another form of communicion.

    But all this is speculation.

    The US runs the navel exercises with our allies with the odds weighed usually in the allies favor, and with random restrictions. We don't learn anything if we always win, and we would discourage allies from participating.
    The US generals pride themselves on being able to go up against same-size or larger fleets and still win. Must have been a shock (or lucky) to find australiens as well trained.

    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!

    I think there is a big difference in a real antenna designed to produce EM waves and powerlines where the sum of the currents equals zero. Despite the US generating a huge amount of power in the 60 Hz range you will have a very hard time picking up the signal in Europe. This in contrast to the ELF signal from a specially constructed antenna.

    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).

    Well, I was on a really old boomer and it was noisy and slow. We had an exercise with a carrier group and supposedly "beat" a destroyer and stuck a blow to the carrier. I do not know how the powers that be can determine such a thing though.
    I know a carrier group can travel roughly 35-45 knots, there is no diesel submarine in the world that can even come close to that pace. Maybe about 1/2 that speed in very short spurts but they would never be able to stay on battery that long. For a diesel sub to maintain a close proximity to a carrier group for "days" and not be detetcted (stay running on batteries), the carrier group would basically have to be standing still. In that case I could probably hit the carrier myself from a raft with a pistol.

    On a side note, I recall our sonar men tracking a fishing boat for several hours, when we finally came to periscope depth, a visual determined it was an aircraft carrier. I assume Sonar men on a boomer were much different then what would be on an attack sub. A boomer hears a noise and turns the other way and gets quiet, no engagement at all. I'd hope the attack guys would be much better.

Most of us are probably less than 6 foot tall and could kick your norwegian ass in seconds. Truth be known that we always got the hand me downs of equipment and made the abosolute best use of it. Our budgets were small so we had to. As far as the snow, we might not have been experts at it solely for the fact that its not as prevailant as it is in Norway where you live in it for 6 months out of a year.

    I absolutely agree with you, but there may be some truth in the US embassy thing.

    During the cold war the Russians embedded all kinds of devices inside the US embassy in Moscow. Some were remotely powered by microwaves (I can't remember the details): they secretly surrounded the embassy with dozens of very high power microwave transmitters. There may be a link between this and the death of the US ambassador from a very rare form of leukaemia.

    This is according to the Mitrokhin Archive, a pretty legit source (and an excellent book - highly recommended for anyone interested in the history of spycraft, the KGB or the Soviet Union).

    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.

    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.

    I once listened to a Navy man describe, at length and with real pleasure, how when he worked at submarine hunting, they'd use passive sonar, and often all they could hear was the whales -- and how, when they got tired of their noise, they would use the high powered active sonar and 'blast them' -- and the whales would "shut up for hours" afterwards. Big fun to make a big animal go deaf-and-blind, eh? I asked what it'd have done to a human diver. He said "fairly close, it would be fatal -- air embolisms." "And to the whales?" "They never complained."

    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.
