"Peter Skelton" wrote in message ... ISTM that there are two possible objectives: 1) deterring the large power from starting a war 2) minimizing the damage a war does to the citizens Countries involved in terrorist-risistance campaigns tend to be unpleasant places to live. Resistance campaigns at home may have some outcome influencing effect (Nam was sold to the American publicv that way), but attacks on the larger country seem counter-productive as Afghanistan and Chechnya (Sp?) are discovering. Possibly non-terrorist strategies aimed at attacking the big country at home would back-fire simillarly. Probably some combination of being a tough nut to crack, giving up something the aggressor wants and persuading others that their interests are served by helping out is the winning strategy. Two countries faced with large, belligerent neighbours in the thirties were Poland and Finland. Neither neighbour could be bought off. The latter did rather well, the former poorly. Are there lessons in their experience? 1. First lesson - Geography matters. Poland is rather flat and good tank country. Finland is not. Even in modern times, nobody wanted to do a ground campaign in the Balkans - the terrain is too tough. Saddam Hussein, military genius, twice managed to manuever (or be manuevered) into playing tanks in a sandbox. Good idea if you got the quantity and quality. Bad idea otherwise. 2.

Lets define "middle ranking" and "war" first. India and China are a far different matter from Pakistan, or SK/NK. I wrote a long list of nations I had in mind in another post. All the ones you mentioned above were on it (IIRC), except NK. The first thing you have to consider is that no middle ranking country could survive an "all out" conflit with the US, which means we want to avoid tactics that might lead to the conflict transforming into such a battle. No nukes, bio's, chems, etc. No direct attacks on the CONUS. This is true. I think one strategy would be to use large numbers of low cost cruise missiles (LCCM). The elements of a cruise missile are all very simple, mature technology, except for the guidance system. Modern computers are small and cheap, so guidance systems can be made cheaply. For china, maybe. Pakistan or Iran or India? less likely. All these countries have access to embedded computer technology; Germany could make cruise missiles 60 years ago, indicating that it can't be that difficult to do, so I expect all these countries could make the other parts themselves. Even LCCM's are fairly high technology, and 'dead reckoning' isn't as easy as it sounds. Why not? Cheap digistal cameras would be very easy to spoof-- smoke comes to mind, Yes, but you can't light fires *everywhere*. and if you start going for IR systems, you've just stopped being "cheap". That's mostly true, IR cameras cost around $5000. Probably it'd be best to have plug-in sensors so ther operator could choose to add IR when it's necessary for the job. Also, computer's and programs that can pick out targets against ground clutter are somewhat more difficult-- note the fact that even now the U.S. still prefers laser guided missiles, and I don't believe we have any autonomous weapons like this in stock (although some are being made ready). The problems are tremendous. sarcasmWell, obviously, if the USA can't do it, no-one else can./sarcasm Another target for LCCMs would be surface ships. Telling tghe difference between a ship and water is easier than detecting land vehicles (detecting what sort of ship it is would also be quite easy, I imagine). Anti ship missiles would probably want ot have a bigger warhead than anti-land force missiles (or a 'swarm' option could be used). More doable-- but if it isn't an active system, well the ocean is a very big place. If it is, then it's either expensive, or very easy to spoof. As for a swarm, how to you choose targets? If there isn't any inter-communiation, your entire swarm will attack the first ship it sees...which usually won't be a major target. If there is inter-UAV communication, you're back to having a very expensive system that even the U.S. hasn't quite figured out, and is far beyhond the capabiliies of most other nations. Swarm co-ordination is a software problem. To solve it, you need a few clever postgrad students, properly managed. The problems is that these weapons wouldn't be "low cost" for other nations-- they'd be major projects, taking forever because most mid-range nations that migbht be in conflict with the West don't have the vast depth of technical expertese we do. But you don't need "vast depth". With the exception of computer and imaging technology, *everything* you need to make a cruise missile is 1940s tech. One example-- low cost bombs using GPS and inertial guidence were developed and fielded by the U.S.-- while the system itself is "low cost" the effort to develop it is anything but. Low cost loitering UAV's and cruise missiles are in development-- in the U.S. and UK. I think maybe China and India might be able to conduct a design effort like you sugggest, but it woudl be hard for them, and I can't see other nations, like Pakistan, any African nations, or even smaller western nations like Austraila, Canada, or Italy being able to even come close. The idea that Italy couldn't make a cruise missile is silly IMO. -- "It's easier to find people online who openly support the KKK than people who openly support the RIAA" -- comment on Wikipedia (Email: , but first subtract 275 and reverse the last two letters). |

Merely having some degree of computer capability is not going to cut it; and likening the V-1 to the kind of autonomous sytem you posit is laughable.

Your LORAN idea fell flatter than a pancake.

You do know what those nifty little stubby, multi-barrel thingies mounted on all of our armored vehicles are, don't you? Yes. But they can't be firing *all the time* just in case they are going to be attacked. True, they could fire when they've spotted an incoming missile, assuimng they do spot it. The missile could perhaps go away and come back 5 minutes later, or it could alter other forces to the target location, or it could fly through the smoke (it travels a lot faster than the targets). Or it could use sensors that can see through smoke -- I'm not sure if IR or radar would work. and if you start going for IR systems, you've just stopped being "cheap". That's mostly true, IR cameras cost around $5000. Probably it'd be best to have plug-in sensors so ther operator could choose to add IR when it's necessary for the job. Now you need a whole new set of target data--more R&D again. I'm not sure it would be that much more. For the main application of spotting moving vehicles you could probably use essentially the same software. Also, the shape of objects under IR is the same as under visual light.

That's close enough for terminal homing to Just to give some figures: GPS will give you 5 to 30 meters accuracy (as long as the US lets you have it). Galileo will give you about the same accuracy. I suppose the US can jam both. I'd guess if they could not, they would not have increased the accuracy publicly available and would make much more of a fuss about Galileo. Loran will give you about 500 to 1000m, on a good day. But as others have pointed out, your Loran will be killed at once. Dead reckoning is much, much worse. As long as you can't effectively counter the influence of the wind, you will not be anywhere near the intended target. Owe -- My from-adress is valid and being read. www.owejessen.de |
