I like lasers, they are very nice and they are very colorful and they can also be your friend.

Star Wars was the nickname given to the Reagan era anti-missile defense shield, but the US Navy looks like they will build the REAL STAR DESTROYER. Directed energy weapons have many obstacles to over come to be effective, least of which is range. Light energy weakens as it passes through a medium such as air. The lenses have to kept clean of salt spray, the lasing rods or medium has to be kept cooled (significantly if reused in rapid succession). This is a daunting task for our state of technology. Then there is the danger to the sailors firing the laser for both eye protection and with high power devices, penetration of body parts.

Good Luck Navy

James, I am a worker in a metal shop in Europe,
and we earn 24$/hour.How in hell can you survive on 12$ over there?

Ferin, we planned for that on one project I worked on. The plane lands, the dying crew gets off and a replacement crew boards to continue the mission. At that point equipment is more valuable than are people.

"Now as to gamma/neutron flux, that is something that really damages electronics"

Unfortunately, it's also rather distressingly damaging to the humans nearby. Besides which, generating large neturon or gamma flux as a weapon would be rather difficult on the battlefield, unless you just want to drop some cobalt 60 or something on the targets. Somehow, I doubt you'd see international or civilian approval of such weapons any time soon.

Nice summation of the conference -- one quibble -- ONR is not a "Navy lab" -- they fund Navy (actually Naval) labs, academia and industry and set priorities for research but they don't really "do" research.

Posted by: JimH at August 20, 2008 10:37 AM

Troll,

The average standard of living today is much much higher than it was in 1960. As much as you wish to idealize that time period, we are better off today. Save your "bleed the rich" philosophy for MoveOn.org.

Posted by: Brian at August 20, 2008 10:23 AM

Old Sailor, congrats for staying on topic & for knowing something about it. Air & land based weapons as well as ship based ones will have to work in mist & in precip to be useful. There's apparently ongoing research in using "blue green" lasers for underwater communication. I know next to nothing about the technology. If there is a wavelength(s) that will get through mist & precip, there's probably not 1 that will both get through dust & hard kill a target. In other words, brownouts are probably not a solvable problem for laser weapons. FELs are theoretically tunable, but within a limited range. You're not going to be able to go from thermal IR to X-rays. They may be looking at FELs because of the waste heat problem rather than the potential of tuning the beam.

For AEGIS cruisers & CV carriers only?
Biggest ships for Lasers.

Reuse old Shore Forts for Lasers??
No more BBs ready.

In 1960, the top income tax on individuals was 92%, to top corporate tax rate was 52%.

I can't find the percentage of US workforce in 1960 that were unionized, but it was certainly far higher than the 12% of today.

Health benefits were not only full coverage, but routinely included dental, and almost everyone had a pension and could afford to attain their version of American Dream.

So according to today's standards the US was a communist state in 1960.

But, seriously, folks.

US corporations were best in the world in 1960. American workers prospered, a sole provider could actually support a family of four, and the worker could stay with one company for life, almost everyone had a living wage.

Why is today different? How is it that companies suddenly claim they can't survive if they have to pay Americans a decent wage or provide benefits?

The answer is excessive greed. The CEO and shareholders (of public companies) are demanding huge margins of any company's profits. They simply do not want to share with their employees. I am NOT against profits, I am against excessive profit-taking.

So they threaten us with moving to China if we don't comply with salary give-backs or they take away benefits or absorb the pension fund.

Today we are told that it is folly to consider that the American Dream is a goal for anyone less than the CEO, or shareholders. We are told that we are 'selfish brats', for thinking that we should get paid as we did 40 years ago - a decent wage for our work.

We are told we are Communists for pursuing the American Dream.

OK back to lasers i have to agree lasers have many limitations and advantages superior range and a infinate suply of ammo essentaly, but the fact that a cloud can weakin it is a sever limitation not to mention that a pressurized gas could be used as a defense not to mention with new heat resistant materials it kinda makes it a iffy thing though like rail guns theyd be superb space based ballistic missile/satelite defenses

Posted by: James at August 19, 2008 08:31 PM

OK Bush Lover ....right your name says it all troll

No believe me i work for just above minimum wage...i wish i could be payed 12 bucks a hr but if i was payed that instead of 8 (mini wage is 7.56 here)oh and have health benefits out my but for every member of my family that means about 10 ppls would lose there jobs or the ppl i work for would go under. Take hollywood for example or heck ive worked factory jobs(soul sucking though they are. Everytime i here about some workers demanding more money you know what i see in my mind factories opening in china.

There is much truth to the idea that we are spoiled brat as a country we are. Look im a capitalist pig if there ever was one but, there comes a point when ppl have to figure out there just going to be hurting themselves when you ask for more pay when the company your working for make good proffits in that yr sure no problem but in a time when many factories are closing and you demand a raise and more benefits and then 3 months later your factory is closed and your like "MUST HAVE BEEN THOSE DAMN CHINESE!!!! THEY TOOK MY JOB!"
realise you did it to yourself.

and yes socalism is evil it destroys the human drive and ambition and turns ppl into mear sheep, and remember marx never said communism and socalism were any diffrent...

and isnt it funny ppl who love bush or republicans or capitalism allways seem to love communist and socalist but then addamently deny there for socalism or communism? weird

Posted by: James at August 19, 2008 03:06 PM

I'm with James.

How dare American workers want to get paid a decent wage? And benefits should only be for the CEOs!

Only a "socialist spoiled brat" would even expect to get paid for their work, so anyone that takes pay at all are Communists - or Socialists, I forget which - but they are evil!

Patriotic Americans that build our state-of-the-art weapons systems should volunteer their labor for the good of the nation. Wanting to get paid for their work means the Islamofascistvegetarianhippies will win!

Posted by: Bush Lover at August 19, 2008 02:31 PM

JD,

During WWII you could buy a hamburger for a nickel. Today you buy a Big Mac for like $2.50. So it's like 50 times more expensive to buy a Big Mac today than in WWII. $20 then X 50 = $1000. It is called inflation.

One reason our other military programs cost so much money is that we don't buy enough to benefit from economy of scale. When you buy 100 airplanes, that is not enough to take advantage of large scale industrial production. Thus, we pay more money for fewer aircraft.

These lasers and other weapons need to be researched. Whether they'll ever make it to the field is irrelevant. Congress will probably cut funding before they ever have a chance to be fielded, but the knowledge we gain by just doing the research is invaluable. If even one of the above projects pans out and makes it into production (even if it is 15 years from now), it will give us a huge advantage over any competitor.

What ever happaned to the economy of scale when it came to purchasing

well if you work in a factory.....you are unions when we want more money more benefits every yr but want to work less and harder

its called communism oh and being a socalist spoiled brat

Posted by: James at August 19, 2008 01:07 PM

The Laser ideas are great. I've believed these were coming since I was in the fleet back in the early '80s and I heard about Reagan's SDI.

The problem with lasers on a ship include fog, rain, or any kind of precipitation which could potentially make them completely useless, for obvious reasons.

The free-electron laser might be able to overcome those problems if it is tunable in frequency so that precipitation won't interfere with the beam propagation.

Posted by: Old Sailor at August 19, 2008 12:30 PM

Let's see, under the upcoming Obama administration, the Navy will need to have "Green" laser's driven by Wind and Solar Power. I wonder how well that is going to work? Can we make stealth Windmills yet? Can we shine the laser at the Solar Panel and still make electricty? Hummm

I'm worried that this laser stuff is a long way off and we may be pouring a lot of money down the old Pentagon Financial Rat Hole for this if we go at it in a huge way. This sounds like a Dream Program for those who are about to retire from the Military and are looking for "Contractor" & Consultant" jobs for a fun filled financially very rewarding, double dipping retirement!!

Remember what President Eisenhower said when he warned us about the MILITARY/INDUSTRIAL COMPLEX. They are out to make money for themselves before they worry about this or any other nation.

During WW-II we purchased M-1 Carines from seveal manufactures for anywhere between $20-50 each, approx. Today,... we pay ONE MANUFACTURER $1,000+ for each and every M-16 variant and have been buying it for 40 years!!!! We only bought the M-1's for 5 or 6!

What ever happaned to the economy of scale when it came to purchasing? GM pays $34.82 for each and every air bag put into the dash board of a Tahoe/Yukon/Suburban we assesmble at the plant here in Janesville, WI. (Iused to work there and we looked at the incoming invoice for a pallet of them!) They sell them to you, for $1,000+! (Good deal huh?) Economy of Scale Purchasing works for GM,... WHY NOT the Pentigon and we Taxpayers??! I bet we've bought more M-16's than GM's made of these 3 vehicles.

The laser idea is great but it's not ready for prime time yet and until it is, we shouldn't be banking on it and setting up huge spending programs until it is.

Here's one laser based landing aid for brown-out conditions:

http://www.oads.com/landsafe.htm

Posted by: bespoke at August 19, 2008 10:57 AM

I'm an idiot in this field (of lasers that is), but doesn't the brown out-condition mean that you can't see visible light, therefore you can't detect lasers etc.? Isn't this the case for GPS vs. Laser guided munitions, due to cloud cover problems etc.?

Maybe it's a laser of non-visible light? Microwave laser etc.?

Anyone able to clarify any more on this for me?

Posted by: Vstress at August 19, 2008 10:40 AM

EMP? Double shielded cables, surge suppressors on all cables that don't possess double shielding, metal enclosures, etc all proved effective against EMP. Now as to gamma/neutron flux, that is something that really damages electronics and suspect that most modern electronics would fail under the assault of hard radiation.

FYI, most if not all, military equipment is hardened against EMP. Civilian equipment isn't hardened.

Posted by: Jack D. Ripper at August 19, 2008 10:15 AM

Now, if the ONR could just develop a technology to keep Navy ship building, on budget & on time. :-)

Posted by: Camp at August 19, 2008 09:22 AM

These lasers are effective, but if i think if we rely too much on them, we place our attack capability at risk of being obliterated by a simple EMP
