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....

      Basically, in order to locate you in three dimensions, the GPS receiver needs to be able to see four satellites. (It's actually locating you in four dimensions: X, Y, Z, and time).

      The satellites, however, not being in different times, cannot triangulate on your time, but instead assume that you are in the same time that they are in (A reasonable assumption). In fact, only three satellites are needed to triangulate on your 3-D position, but due to various atmospheric conditions that vary the amount of time for transmission, and therefore vary the distance estimates, a fourth satellite is always used for error checking. With four satellites, you have four combinations of three satellites, with each combination giving you a 3-space estimate. You can then average these four estimates to get a more correct position. The more satellites, the more pieces of information you can apply to the problem, and the more correct your estimate -- which is why seven is often the prefered number for most civilian applications. Even with seven, though, there are errors, so all data collected with GPS units should then be corrected by referencing it to a nearby base station with a known exact location on the earth's surface.

      As for the other post that suggests the reason 3 can be used is because the system knows you are on the Earth's surface -- this assumption would be true if, 1) the system made such as assumption, and 2) the Earth's surface were smooth.

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).

  22. ELF, the science thereof by Ancient_Hacker · · Score: 4, Interesting

    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).

  23. A good story about this by DG · · Score: 5, Interesting

    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.

  24. Personal Experience by DG · · Score: 4, Interesting

    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.
