Tesla was a Serbian American. Modern America might very well not be as it is today without his genius.

I find it hard to believe that the congress at the time was less liberal than Carter

Read: MORE liberal than Carter.

Wooo Boy. Time to turn in. G'Nite!

Agreed.

Early rockets were spin-stabilized. They are not any longer.

The scheme referred to here was to make the ICBM as shiny as possible and spin the upper sections so as to spread the heat of the laser as much as possible.

Another possible countermeasure is to release a metallic cloud or fog from the nose of the missile so as to reflect as much of the beam as possible.

Call me a skeptic, but I ain't buying that we are even remotely close to implementing this type of technolgy.

We are, it is the Israeli THEL system. It has passed ground tests and is being built in Israel as we speak. Starwars is alive and well... in Isreal. The Israeli Arrow anti-missile system that is a generation in advance of our patriot system has been approved by congress to deploy around American Cities too. (But that is off thread)

The inovative part is only America can build a big enough plane to put one of these in the sky. Pretty awsome. If it can blow a speeding skud out of the air, imagine how it will do against fighterplanes.

"Early rockets were spin-stabilized. They are not any longer."

I know that, but it is easy enough to go back to spinning, if desired. At what point in the boost cycle it would be best to impart the spin is an engineering problem. I would guess that the easiest would be to put on the "spin" just at the end of the boost phase, when the warhead "goes ballistic".

During Desert Storm a decision was made not to deploy "operationally" one laser system that was designed to destory enemy optics. I also know of soldiers at the DMZ who would "laze" North Koreans with an AN-GVS-5 (lazer range finder) when they would look through their binos. I don't know the reasons, but my guess is that JAG types claimed it was inhumane.

Yes, but note the article refers to hitting the missile DURING the boost phase, not at the end.

And spinning an ICBM during boost is much more difficult now than it was in the early days.

Trying to spin missiles not designed to be spun would cause mucho problems with the new forces now exerted on the vehicle, flame flow thru the nozzles, etc.

It would probably be necessary to redesign the vehicle from scratch.

Nope, wrong. The only thing it might effect is a liquid-fueled rocket due to centrifugal forces on the fuel tanks. Solid fueled boosters won't be effected.

The key point is that doing a design that allows spin works from KNOWN TECHNOLOGY. Nothing new has to be developed or invented.

I can tell you that from some tests I was involved with at NASA, if you try to spin a shuttle SRB you will have big problems and a pile of scrap.

Flight vehicles are designed to handle certain forces from certain directions, and only those forces.

Over-design adds weight, and weight is bad.

If a vehicle is not designed to spin, it probably won't stay together if you spin it.

In other words, not using lasers to initiate nuclear reactions but just the opposite: using a nuclear reactor to generate laser light. Much more powerful than chemical lasers, much more compact,

Nuclear reactors are NOT compact.

Nuclear Reactors can be built very compact.

It's all that shielding that's bulky. ;-)

You are being deliberately obtuse. The POINT I am trying to make, and that you seem unable to grasp, is that WE KNOW HOW TO BUILD THIS KIND OF STUFF ALREADY--I AM NOT SAYING THAT YOU CAN DO IT WITH EXISTING HARDWARE--IS! THAT! CLEAR! ENOUGH! FOR! YOU!

Maybe not deliberately obtuse. ;-)

In reading back over your posts, it sure seems like you were saying that the enemy would just start spinning their boosters. And they can't.

If you're talking about them completely redesigning all their boosters, you're looking at an 8-10 year timeframe.

By that time our lasers will be so powerful that, spin or no spin, we'll punch right thru.

"an innovative system that could end up arming a series of powerful satellites able to target anywhere on the Earth’s surface with near impunity."

Soon they will know the POWER of this FULLY OPERATIONAL DEATH STAR . . .

How many minutes have you spent studying the physics of nuclear powered lasers? Try calculating how much energy could be created in the gas tube that would be output as a laser beam using your expertise in gas pressures, neutron fluxes, isotope cross-sections, heat removal, etc.

I think you're really replying to the wrong guy. I wasn't really talking about nuclear-powered lasers.

I was merely joking about "compact nuclear reactors"
