Which does them absolutely no good at all.

which is quite long according to news reports, though it's getting

They aren't 'auxiliary codes' at all. Military GPS data streams are
encrypted. You need keys to use them. Without keys you get nothing.
This is why copying a GPS weapon exactly does you no good.

:Assuming (as I suspect) that "auxiliary code input" to the weapon is
:required, things get more complicated. Basically the question is how
:long it would take for the enemy to figure out what the auxiliary code
:was to activate their weapons.

Longer than the key is good for. They change frequently, you see.

:Pessimistically assuming that the current military GPS system does get
:compromised, and that the code breaking process could be done in
:minutes, the US is of course free to build a better one with more
:modern (and longer) codes. Of course, retrofitting existing weapons
:to use the new GPS system might be a bit involved. OTOH, it could be
:as simple as pulling out a modular "black box", and replacing it with
:a new improved one.

Well, if you assume the enemy has magical powers (which is essentially
what you're doing above), then I suppose anything is possible. Just
by the way, even your "black box" replacement above isn't simple.
Examine the replacement of PPS-SM by SAASM, for example.

You know, if you want to keep speculating, you might want to learn a
bit of something about the GPS system before you continue. See
http://gps.losangeles.af.mil/user/pr...curity/hae.htm for a
very brief synopsis on GPS security.

This is rather like saying that nuclear weapons aren't hard, once
you've invented a nuclear weapon. If you really find this easy, do I
have a career for you!

:Weapons like this were in existance 20 years ago, for example the
:Exocet anti-ship missile.

Exocet does nothing at all like what you describe above. It flies
inertial with an active radar homing head. Yes, we've had that sort
of thing for quite some time. It works very well when it comes to
finding big radar reflectors like ships among all that flat water.
ATR systems (which is something different than what radar guided
weapons do) is a much tougher problem.

:I'm not bsure what problems you envisage

I could, but then I'd have to kill you....

:because you can't just fire them "in that direction, more or less", and hit
:anything--you have to have a pretty narrow determination of where the target
:is right at the time the weapon arrives.
:
:What you could do is have the missile, if it doesn't find a target
:to hang around in the area looking for one. (The British ALARM
:missile does this literally :-)).

ALARM is an ARM. Again, this is a much easier problem than ATR.

:Now if you want to send a flock of

:harder, I agree.

Discriminating vehicles from ground clutter is a lot harder, period.

:(b) Are you going to send it in low, where it

:

You might want to look at the accuracy of DTED and how much data you
would have to load to your missile.

Requires good IMUs. Even then, your accuracy is going to degrade

You imagine a lot of things. That's about as far as most of them
could go in the real world.

Now look for something that can encrypt a video stream in a secure and

above.

I'll tell this to the folks on the SLAM-ER team next time I'm in St
Louis. I'm sure they'll find your contentions about how easy this is
to do about as funny as I do.

No doubt. But they're not producing things that your average tribe

I predict you're probably wrong.

What would be sensible strategies/weapons for a middle-ranking
country to employ if it thought it is likely to be involved in a
war against the USA or other Western countries, say in the next 10
years?


To deal with the US Army...
Use SUVs with anti-tank rockets and a millimetric radar mounted on
the back. In iraq US gunners opened fire at 5miles. Since the
rounds travel at a mile/second, this would give an SUV 5 seconds
to dudge, which would be simple with guidence from the radar.
Meanwhile the top-attack missiles tear through the thin turret
roofs. Buy a few otto-76mm armed tanks with dual use surface/air
to deal with incomming aircraft/missiles/bombs/helicopters and to
rip enemy soldiers to pieces.


5 seconds to dodge... Dodge where, exqctly? In what direction? How
much? To be at the least effective, you're going to have to somehow
get 1 vehicle's size distance away from where you were. Since SUV's
don't move a 1 mile/second...
Oh, and what if the Rascally Americans don't open fire at 5 miles
Becasue there's in a city, or there's intervening terrain, or you're
not a visible target, and engave at a shorter distance? (Which is
what happens. Even 500m (1500') is long range when you're not
shooting at, say, Iraqi tanks in the open desert. In that case,
they wouldn't be engaging SUV-type things with Main Gun rounds.
('cause it would go through the SUV, and the SUV behind the SUV,
and the Tree behing the SUV behing the SUV, and the School behind
the tree - you get the idea) They'd use either the .50 cal MG on
the turret top, or teh .30 cal co-ax. (Don't discount the Coax.
It's got a dedicated gunner with a telescopic sight, a laser
rangefinder, and is mounted on a 65-ton tripod. In that case, you
don't have 1 round to dodge, but several dozen.

As for the top-attack missile - when is it going to be fired? Who's
going to guide it? How are they going to maintian guidance for the
20-60 seconds it will take to reach its target while riding in a
moving/evading/exploding SUV?

To deal with the US Air Force...
Buy old airliners and fit with reloadable missile launchers and
modern AA radar, counter measures, and refueling probe. Take old
fighter designs, and hang them fully fueled and armed from
ballons. That'll multiply thier endurance by a factor of ten at
least. Fit search-radar in envelope and have them patrol your
boarder. Network them together and you'll have an end to surprise
US attacks.


I'd pay good money to see an F-104/Mirage II/MiG-21 launched from a
balloon.If you could make that one work, Ringling Brothers would
give you a contract But Quick. As for refrobbing old airliners as
long-endurance Patrol Fighter AWACS - well, first, they're easy to
detect, and therefore, neutralize. You can either shoot them down,
or go around them. Being airliners, their ability to move
crossrange will be poor. They'll also need improved airbases, and,
as you mention, tankers. WHen the bases disappear, so does your
Air Defence. (It's always struck me as amusing how many folks seem
to think that all you need to improve aircraft range is a probe.
You also need tankers. Lats of tankers. Lots of big tankers.
Consider that in 1982, the RAF used its entire tanker force to get
one Vulcan from Ascention Island to Port Stanley. (Victors, in
this case - Not a lot of tankers, and not a lot of transfer fuel.
The same mission could have been flown, by the U.Ss. with 3
aircraft - 1 B-52, and 2 KC-135s. The U.S. tanker fleet alone
outnumbers most other nations entire Air Forces.

To deal with the US Navy...
Buy old torpedos and fit to larch home made rockets (see X-prize
entries) with 50-100 mile range. Get the rockets to dump the
torpedos within a few miles of a nimitz carrier groups and you're
garanteed to blow up something *really* expensive!


A _lot_ harder than you think. And the launches will be detected. A
Numitz at flank speed would be a significant distance from the
inital impact area before the Super ASROC you've described gets
there. At which point, the torp, if it survives the impact intact
(not a trivial thing), is goig to have a hard time finding a
profitable target. In the meantime, you've now 1: Revealed your
intentions in an unambiguous manner, and 2: Nicely marked all of
your launching sites. making it damned hard to clain that it wasn't
your doing. Teh end effect, even if you do hit a ship, would be an
awful lot like kicking a nest of Africanized Bees.

Alternatively buy the following:
1 million RPG-7s
5 million RPG-7 rounds
10 million AK-74s
1 billion bullets
Distribute evenly through out your population, train them, set up a
Swiss-style monitoring system, and let the Americans invade. Then
blow up everything of value they own the second they let their
guard down. They'll leave in a few months and you can go back to
normal.


In order to do that, you have to have a population that thinks the
country you're leading is worth fighting for. But then, countries
that its citizens thing are worth fighting for tend not to be high
profile targets to the U.S.

Alternatively fly a few airliners into american nuclear power
stations. The aftermath of multiple chernobles will destroy
America as an effective strategic power.


Well, the onlu problem with _that_ one is that Chyernoble, bas as
it was, didn't depopulate large stretches of the Ukraine or Russia.
U.S. racotrs have far superior containment, and, in fact, are
required to be designed such that they can shrug off a direct hit
from a large airliner.

You are the illegitemate son of Robert S. Macnamara, and I claim my
5.00!


I support Peter's claim to the Fiver.
John's cutesy-pie combat methods were interesting, slightly, but
suited to a 1930's Boys' Book of How to Have a War.
Peter did a fine job of dismissing them all.
And I especially agree with the last one - countries where all the
citizens are heavily armed are not countries like Iraq, where people
the ruler doesn't like get fed alive into shredding machines. So they
aren't the kind of country we'd be needing to invade.

The issue isn't programmers Phil. The issue the massive amounts of
R&D to develop the information needed to specify the sensor that the
programmers will process the output of.


The sensors needed are visual and IR imaging. It doesn't require a
massive R&D program to determine that, or to decide which
combinations of number of pixels and widths of field of view are
appropriate.


It doess, however, require a massive R&D program to be able to
identify the target in the image - if you're lucky enough to have the
target in the Foeld of View of the sensor in the first place.
Recognizing the shape of, say, a vehicle, from an arbitrary distance
and aspect angle, even without the complications of camouflage, smoke,
or decoys, is far more difficulet than you are imagining.
You aren't even beginnig to consider th promlems involved with, say,
telling an Armored Personnel Carrier from a Dumpster, or an Atesian
Well Drilling Rig from a missile TEL.

The issue is the massive
amount of R&D needed to develop the algorithms the programmers will
implement to analyze the output of the sensor.


Do you know anything about programming? If you did, you'd know that
developing algorithms is what programmers do.


Oddly enough - I do. In fact, I've done developmnet work on Image
recognition for about 15 years out of a 25 year career as a Programmer
and Project Manager, much of it for just the purpose you describe.
Derek has far more of an understanding of the problem than you do.
It's actually easier to do what seem to be very difficult things -
like taking an image of a car's license plate as it travels on a
highway /2 mile away, than it is to identify the vehicle itself.

Used to be popular for cruise missiles in the 50's and early 60's, but
the units were pretty good sized. I have no idea if anyone is
actually working on them today.
