Re:Nobody should be surprised...
I too was somewhat surprised that underground Nukes weren't used in Afghanistan. The attack on the WTC was the equivalent in destructiveness of a small (100t-1kt) nuke, and used on civilians. That the US didn't use Nukes in return is a sign that someone up there was thinking. A bit of research shows why they didn't use them. Have a look at report called "Low-Yield Earth-Penetrating Nuclear Weapons". The standard penetrator (B61-11) has piss-poor penetrating performance. Even a 100t nuke needs to be 70 metres down to avoid contamination.
Most of the Great Unwashed out there in slashdotland don't make any distinction between a 100t nuke and a 50 Mt nuke. But it makes a big difference to people nearby. For example, if you're 100 km downwind of a 100t underground nuke, you'll only detect it by watching CNN. If you're 100km downwind of a 1 Mt groundburst, you're dead from fallout. It's Ten Thousand Times more powerful. Both India and Pakisatan let off dozens of kiloton-range weapons not so long ago. Using nukes doesn't mean Instant Thermonuclear Global Death.
For everything you ever wanted to know about Nukes, see the High Energy Weapons Archive. The Federation of American Scientists may not be the most neutral and unbiased of commentators (very Liberal), but the facts they base their commentary on are unimpeachable. Anyone who pretends to hold an opinion worth anything should read the facts first.
Incinerating Baghdad - and a whole heap of babies, schoolkids etc - would be a really bad idea, literally unthinkable even if Saddam Hussein nuked the US. But using nuclear bunker-busters to target the people who pushed the button, rather than leaving them untouched and massacring civilians, that makes sense to me. And obviously to the US Military too.

Re:Nobody should be surprised...
after the first time that you don't use a nuclear weapon in response to an apparent breach, you lose considerable credibility.
Credibility is a difficult thing to calculate, particularly when dealing with essentially irrational opponents like Al Qaeda. If enemies like Al-Qaeda were unimpressed by Desert Storm and the Serbian bombing, or Hiroshima for that matter, I can't imagine how America's credibility enters into their calculations.
It is likely that careful use of nuclear munitions could have made collapsing many of the tunnels much easier...
According to the newspaper articles, which constitute my complete knowledge of the subject, the caves were widely dispersed over 10 square miles. Using tactical nukes to carpet bomb caves sounds like massive overkill. If the location of the caves were known, as they apparently were, conventional ordinance should have been more than enough to deal with them.
Modern TNW minimize the size of their fireballs, while maximizing blast overpressure. This has the effect of placing immense pressure against the target while leaving almost no fallout.
The Effects of Nuclear Weapons appears to be online here. I'm not claiming to be an expert but the paper seems to say that for zero radiation to reach the ground from a 20 kiloton weapon, the device would have to be detonated 2 miles in the air. If this height did not produce the cave-crushing shockwave you need, it would have to be detonated lower, which would produce radioactive debris. In addition, Tora Bora is mountainous terrain, which means that to affect a cave near the base of a mountain, the nuclear explosion would necessarily be nearer the top of the mountain, which would therefore produce fallout. Further, the higher the altitude of the explosion, the fewer caves would be affected by the explosions and the more nuclear explosions would be necessary.
In fact, a nuclear use might have sent an important message with regard to US policy in regard to the "war on terrorism".
There must be better ways of sending such a message without appearing to legitimizing the use of weapons of mass destruction and conceding the the moral high ground in the mind of America's allies.

Re:What exacly are they trying to learn?
Actually, they are comparing the simulation with real world physical test results. When the simulation is tuned well enough to match the actual results of a test shot, then they will probably change the device parameters of the simulation code to model a differnt actual test and see if the results are still valid. At some point the simulation code will be deemed first order reliable and can then be used for testing new concepts for weapons designs. As an example of why this might be usefull, consider that there may have been advances in the chemical high explosives used in the systems as well as advances in the command/control and safety systems relative to what was designed into weapons made in the 1950s or 1960s or even later. If it were possible to re-use the nuclear components of old weapons in a new bomb design with modern insensitive high explosive and more reliable detonation/control, denial of use and other safety systems, how could we put such a new weapon design into the stockpile without testing ? Accurate computer simulation may provide enough confidence in such a re-design to allow its certification for stockpile use. The ability to re-use the old nuclear components would eliminate significant hazards of handling these dangerous and exotic nuclear materials in processes such as re-casting and machining.

Re:Rigging as a Business Practice
Rigging for a demo is one thing but rigging for testimony in a cout of law is another.
found a couple of sites that explain the law a little more clearly. I hope
Maine Law
and Vt Law
an excerpt from the VT law.
"RULE 3.4 FAIRNESS TO OPPOSING PARTY AND COUNSEL
A lawyer shall not:
(a) unlawfully obstruct another party's access to evidence or unlawfully alter, destroy or conceal a document or other material having potential evidentiary value. A lawyer shall not counsel or assist another person to do any such act;
(b) falsify evidence, counsel or assist a witness to testify falsely, or offer an inducement to a witness that is prohibited by law;"
followed by
"Documents and other items of evidence are often essential to establish a claim or defense. Subject to evidentiary privileges, the right of an opposing party, including the government, to obtain evidence through discovery or subpoena is an important procedural right. The exercise of that right can be frustrated if relevant material is altered, concealed or destroyed. Applicable law in many jurisdictions makes it an offense to destroy material for purpose of impairing its availability in a pending proceeding or one whose commencement can be foreseen. Falsifying evidence is also generally a criminal offense. Paragraph (a) applies to evidentiary material generally, including computerized information."
to note: computerized information!!
If we were in china it would look a little diff.
China
"Article 306. During the course of criminal procedure, any defender, law agent destroys, falsifies evidence, assist parties concerned in destroying, falsifying evidence, threatening, luring witnesses to contravene facts, change their testimony or make false testimony is to be sentenced to not more than three years of fixed-term imprisonment or criminal detention; when the circumstances are severe, to not less than three years and not more than seven years of fixed-term imprisonment."
Well if it were anyone besides MS I believe the trial would start new now.
Oh well I'm not an expert on these things.

Bush cuts the nano technology budget.
Oh science is so competitive, why dont you ask the Scientists for once and not the businessmen.
Ask a programmer working on an open source project if hes competiting, ask a Scientist who wants to solve the mysteries of the universe out of curiosity if they are competiting.
Some people are in science to compete, but the great elite scientists are fueled by a passion greater
And when you go to places like China where everyone is poor, people suddenly arent as selfish, they share.
Sharing is going to be key because you can only compete so much before it starts to harm you
If everything in life were a competition alot of people wouldnt become scientists because they cant compete, people wouldnt try sports because they cant beat everyone they play.
Competition is good for business, bad for science, this comes directly from the scientific community who happens to be against patents.

Combat?
This thing seems way too small to fit some kind of weapon. For this to be useful in combat, it'd have to carry a machinegun or maybe a small rocket launcher. A machinegun with 1000 rounds would weigh, say, 15-20 kg, and the recoil would probably be too big for this chopper.
The recoil of a rocket launcher, on the other hand, would be minimal. Problem is to aim the pod, since you can not adjust fire during firing in the same way - since you would carry only, say, 10 rockets. The aiming problem would mean you'd probably have to include hydraulics for tilting and rotating the pod, wich means more weight.
'course, you could just pack the thing with 15 kgs of plastic explosive, fly it into a building full of your opponents of choice, and set it off.
The Hellfire missile used on the Predator UAV, for example, weighs 45 kgs. Obviously, this is too much for this litte chopper.
I wonder how this extra weight affects flight performance. Does anyone have any more info on this? -

Re:Making movies is not cheapEven for the military, there isn't much need for a maneuverable drone.
The Comanche costs (will cost? may cost? link is from 1997) $26M each. Even at the current cost that means approximately 650 of these helecopters for the cost of one Comanche. They are (were?) taking about buying 1600 Comanche helicopters. That works out to 1,040,000 drones for the same cost.
Imagine you add a saturday night special to the helicopter and you send a million of these things sweeping into Iraq. Now the only problem is finding enough trained pilots.
Wait. Scratch that thought. I just had a vision of a million, unsupervised 14 year old boys in control of armed, remote control helicopters.

Rocket-powered lasers (really)This sounds a lot like some of the rocket-powered gas lasers proposed for Reagan's "Star Wars" project. The MIRACL laser first worked in 1985, produces megawatt-power continuous beams, and is still used now and then. MIRACL burns ethylene in nitrogen trifluoride, which generates free, excited fluorine atoms. The exhaust from combustion is mixed with deuterium and helium, and the resulting gas mixture is then lased in a mirrored cavity. So it's really lasing rocket exhaust.
But MIRACL is using a far more reactive fuel at far higher temperatures than anything you find in auto exhaust.

Re:Must fit in cargo container
by killthiskid on Wednesday January 30, @01:47PM
Well, since the vehicle has to fit in a 20 foot container, you should have an absolute upper weight limit of about 25 tons. Quite a lot you can do with that. They'll probably lower it to 15 tons or less, still a respectable weight.My first thought was to use the body of an M113 APC, but the vehicle must fit in a 8 x 8 x 20 cargo container for shipment to England. The vehicle can be disassembled for transport, but it has to be able to be put back together in under four hours. Damn!
We could actually see something based on military vehicles entered. The Scorpion family of vehicles fits the bill quite nicely, even if all you are allowed to use is the motive system. You should also see converted bulldozers and the like. Except for speed, tracks will probably have the advantage.
It isn't totally unbelievable that defense contractors will enter or sponsor teams. If so, the sky is pretty much the limit. Will the final be Alvis versus General Dynamics or KMW versus United Defense?
I will certainly be looking out for this!
Death on tracks!

Re:Two questions ...
According to this, the M1 won't fit in a shipping container in any direction. Damn.
According to this link, however, it will fit the height requirement, but you'd still have to smash the hell out of it.
www.fas.org/man/dod-101/sys/land/m1.htm Here are the stats from another site:
M1 Abrams Main Battle Tank
UNCLASSIFIED
Crew 4
Length overall 9.766m
Width 3.653m
Height 2.885m
Ground Clearance 0.432m
Max speed on road 72.5km/hr
Range 500km
Engine power 1,500hp
Main gun 120mm
Weapon Range 1,846m
Not to mention the fact that the three teammates would be really busy doing the work of four soldiers. So NO, the M1 won't fit into a shipping container. -

15 megatons is large even for military weapons. Most weapons in the US arsenal are 100-500 kt weapons, with only a few reaching above 1 megaton (Yes, we used to have a 25 megaton monstrosity, but those have been retired). It takes a lot of complex engineering and expensive materials to create a thermonuclear device. It's more likely they'd use a fission device which would peak at 500 kt (Largest ever fission device - Ivy King 1951).
- All of these countries have been hit by at least five Titan II ICBM's.
This is the most glaring error. Titan IIs were deactivated throughout the 1980's, and were completely deactivated in 1987. So unless you're implying that one of our embassy workers went out and threw model Titan II paperweights at people, this isn't too likely.
Also, your target choices are kinda sketchy. We aren't upset with India, we're not too upset with Pakistan and the Phillipines, and Afghanistan and Somolia are festering shitholes. Iraq is really the only target in that list with even a remotely realistic chance of getting nuked.

That's about what you have to do! Really!According to the NCSC and DOD this is about what you have to do to insure it will not be recovered.
Forest Green Book from the NCSC.
"A Guide to Understanding Data Remanence in Automated Information Systems is intended for use by personnel responsible for the secure handling of sensitive
or classified automated information system memory and secondary storage media. It is important that they be aware of the retentive properties of such media,
the known risks in attempting to erase and release it, and the approved security procedures that will help prevent disclosure of sensitive or classified
information. This version supersedes CSC-STD-005-85, Department of Defense Magnetic Remanence Security Guideline, dated 15 November 1985."
"5.1.3 DESTRUCTION
It is good practice to purge media before submitting it for destruction. Media may generally be destroyed by one of the following methods. (Although
approved methods, options d and e use acid, which is dangerous and excessive, to remove recording surfaces. Options a, b, and c are recommended over d
and e.)
a. Destruction at an approved metal destruction facility, i.e., smelting, disintegration, or pulverization.
b. Incineration.
c. Application of an abrasive substance (emery wheel or disk sander) to a magnetic disk or drum recording surface. Make certain that the entire
recording surface is completely removed before disposal. Also, ensure proper protection from inhaling the abraded dust.
d. Application of concentrated hydriodic acid (55% to 58% solution) to a gamma ferric oxide disk surface. Acid solutions should be used in a
well-ventilated area only by qualified personnel.
e. Application of acid activator Dubais Race A (8010 181 7171) and stripper Dubais Race B (8010 181 7170) to a magnetic drum recording surface.
Technical acetone (6810 184 4796) should then be applied to remove residue from the drum surface. The above should be done in a well-ventilated
area, and personnel must wear eye protection. Extreme caution must be observed when handling acid solutions. This procedure should be done
only by qualified and approved personnel.

about 80%. The big ass electron gun is really equipped for the atomic age. Maybe, eBay and Amazon will office us a choice of "radiation hardening" as gift wrap for our electronic gadget.

Re:A reason for funding?
I can't remember the numbers exactly, but I believe a 5 MT warhead groundburst will leave a crater 200 m in diameter. It follows, then, that a weapon of this size should be sufficient to vaporize or pulverize meteors in the 100-200 m range (especially meteors of stony, rather than metallic, compostion). The practical size limit for nuclear weapons is ~100 MT which I think should handle anything up to 2 Km diameter. And somewhere in the bowels of the DOE I'm sure someone is busy researching antimatter boosted fusion weapons.

Early bomb designs(1): Many people seem to believe the first Atomic bomb was composed of two half shells with a surface area-to-mass ratio too low to cause a chain reaction when separate, but high enough when attached to eachother. That is not the case. The active material was mixed up with moderator, and encapsulated in a metal sphere. Explosives placed around this sphere would compact the material, thus reaching chain reaction density. It was important that the sphere remained a sphere with very high accuracy so much tinkering with the placement and detonation of the surrounding explosives was needed. It was not only production of enough active material that kept other nations from developing nuclear weaponry, also technical "details" like the above mentioned. US has most of the leading scientists in their labs.
There's some confusion here about gun-type designs vs. spherical implosion systems. Trinity was the first test of spherical implosion, using plutonium. Hiroshima was a gun bomb, with two subcritical pieces of U-238 forced together with a gun-like arrangement.
Incidentally, those aren't the only possible geometries, just the simplest ones. Linear implosion was developed in the 1950s. Other geometries have been developed, but are still classified. As greater compute power has become available, it's become possible to simulate, and thus design, more complex implosion geometries.
This is a major argument for export restrictions of "supercomputers". Still, all the major developments in nuclear weapons were made in the 1940s, 1950s, and 1960s. Every desktop machine today has orders of magnitude more power than the supercomputers of the nuclear establishment in 1970. It's not clear why we still have "supercomputer" export restrictions at all.

Thermobaric not hyperbaric...Quoth Katz: "The Predator spy plane and other unmanned drones and gunships (along with satellites, thermal imaging devices, X-ray scanners, etc.) not only search for the enemy, but fire guided missiles, drop powerful oxygen-sucking hyperbaric bombs, and guide bomb strikes from afar."
The BLU-82 Commando Vault (also known as the Daisy Cutter) is a 15,000 lb. thermobaric bomb, not "hyperbaric" as he calls it (although I suppose it makes sense in the way he uses it). And they certainly aren't dropped from unmanned planes. They are pushed out on skids from the back of Special Operations C-130s (or perhaps AC-130s).
For more on the Daisy Cutter and other thermobaric weapons, check the following links:
Also notable: The bomb used in the beginning of Outbreak (1995) was a fuel air explosive similar to the Daisy Cutter.

DoD Will Implant Chips in Troops by 2025
From the USAF report Air Force 2025:
Ethical and Public Relations Issues.
Implanting "things" in people raises ethical and public relations issues.112 While these concerns may be founded on today's thinking, in 2025 they may not be as alarming. We already are evolving toward technology implanting. For example, the military currently requires its members to receive mandatory injections of biological organisms (i.e., the flu shot). In the civilian world, people receive mechanical hearts and other organs. Society has come to accept most of these implants as a fact of life. By 2025 it is possible medical technology will have nerve chips that allow amputees to control artificial limbs or eye chips that allow the blind to see.113 The civilian populace will likely accept an implanted microscopic chips that allow military members to defend vital national interests. Further, the US military will continue to be a volunteer force that will freely accept the chip because it is a tool to control technology and not as a tool to control the human. -

Designed in response to recent declassification of a Russian "stealth" warship and as a countermeausure to the National Missile Defense.

Re:Re-engined B-52sYou're partially right, my source does say 650 mph.
But, the speed of sound depends on the density of the medium:
v = sqrt(B/rho)
where v = the speed of sound, B = the bulk modulus of elasticity of the medium, and rho = the density of the medium.
Since air density changes with altitude, pressure, and temperature, the speed of sound also varies. In general the speed of sound in air, at 70F, at sea level is 1129 ft/sec = 770 mph. -
Re:What a bunch of trash
Mig-31 has the same characteristics (Mach 3), and is still on duty (it's an evolution of Mig-25).
Actually, the Mig 31 is heavier than the 25, so its max speed is only Mach 2.83, see this. Also, the Mig 25 is still in service with a number of countires.
But i think that the famous U2 (it's called TR-1 in latest evolutions), was shot by a SAM, not that Mig.
Right, when Capt Gary Powers was shot down in 1960, it was an SA-2 that shot it down. However, the TR-1s and U-2s are all designated U-2 now, see this.
BTW, SR-71 shouldn't have been called that way, it's a mistake from Carter. I think it should have been RS-71.
Almost, actually it was Lyndon Johnson, and it may or may not be true. An AF Col that flew the SR-71 tried to get to the bottom of this legend, see this (bottom of page). -
A-10 WarthogAnother slow, ugly but wonderfully effective aircraft that looks set to be in service well past most people's expectations (including the Air Force) is the A10 Thunderbolt II (a.k.a. Warhog).
The A10 was originally projected to be good for 8000 flight hours, now they're planning to keep them in service for up to three times that. There's a detailed description of the updates and overhauls they plan use to keep the A10 in service on FAS.org's A10 page.

Re:Good design = scaryAlthough, didn't the USSR have a long range bomber like the B52 that was a turboprop?
Yes. The have (had?) the Tu-95
/142, NATO codename Bear heavy bomber. They used to be intercepted over the northsea all the time by aircraft from the squadron where I served.a propeller plane that could go stratospheric and insanely fast.
It also was insanely loud

We should build more!
After that B1-B crashed in the Indian Ocean last Tuesday, due to "multiple malfunctions," it makes me wonder why we're even using B1-B's in the Afghanistan conflict, after having achieved extreme air superiority. As this article points out, the annual budget to maintain all 94 of our B-52's is about $250 million, while the cost of a new B1-B is $280 million. B1-Bs are faster, can fly lower, avoid radar better, and have better electronic counter-measures, but the biggest cause of loss to our bombers crashing isn't speed, altitude, radar detection, or anti-aircraft missiles, it's that they break! It's hard to say what the cost would be to build new B-52s, since the last active B-52 was built in 1962, but it would sure be cheaper than the $280 million each for B1-Bs.

Other long-lived weapons
All the armed forces keep weapons around for a long time. The Army has used the M113 armored personnel carrier since '60, and apart from engine swaps (which the B-52 gets, too), they're still running around. It's also been used as the basis for countless other vehicles, and it would suprise me greatly if it didn't hang around another 40 years.
Along the same lines, the Army and Marines hung onto the M1911, the (in)famous Colt .45, for an insanely long time. It was introduced in 1911, and saw action in horseback cavalry charges when Pershing was going after Pancho Villa in Mexico. It started to get replaced by the M-9 in 1986, but was still very much around during the Gulf war. 80 years of service life, unmodified. Not bad.
And then there's the C-130 and all its variants. I know guys whose granddaddies jumped out of them. They're going to be around a long time, too. -

Re:Sea Shadow
Some inaccuracies in your post:
- "Stealth ships" are a blue-water navy idea.
- Here, you're half right. But the technologies that arose from the development of Lockheed's Sea Shadow are being implemented into current designs, such as the DD-21 Land Attack Destroyer and the LPD-17 San Antonio Class Amphibious Ship, as seen by their sloping sides and angled exhaust stacks.

- Armor matters more.
- Interesting you say this, since most modern ships are lightly armored. (Not armed - note the distinction.) Witness the gaping hole in the side of the USS Cole from a small boat of explosives. And many people would say that stealth matters immensely as more and more rogue states acquire castoffs from the former Soviet Union.

- There's a good argument for heavily armored battleships for shore bombardment...
- The ERGM (scroll down for a description of it) has a range far greater than any 16-inch gun ever did. In addition, guided munitions such as the Tomahawk and the ERGM are much more accurate and precise than 16-inch gunfire is, allowing for fewer shells fired and less chance of friendly fire casualties.

- The U.S. Navy had an "arsenal ship" concept in the early 1990s, but never built any.
- The Navy is still reviewing this design, actually - you can see an overviews, histories and diagrams of it here, here, and here. One of the many, many reasons that it is currently in limbo has to do with a proposed plan to retrofit some of the oldest Ohio-class submarines to carry 154 Tomahawks and a SEAL team, which would duplicate the effort being expended to design an arsenal ship. The DD-21 is another duplication of effort issue further muddying the outlook for the arsenal ship, as its explicit job is land attack.

Re:are artillery shells that delicate?
Also, one of the shell's main tasks is to provide material for shrapnel. I served in the Swedish army, commanding a 155 mm FH 77B howitzer unit. In the construction of the projectiles you have to consider that you want as much explosives as possible in a ballistically functioning unit at a feasible price. The shell can't be too heavy, but you still want it to sustain the enormous forces developed as 45 kg is accelerated to >800 m/s during a millisecond or two - and it's supposed to make some shrapnel as well. Only 10 kg of plastic explosives wouldn't waste many Russians (or Pakistanis, as our late peace-loving PM Olof Palme sold these babies to India (and sold our country to the Soviets)).
