__________________________________________________Hezbollah’s Katyusha rocket attacks have killed and wounded dozens of Israelis, destroyed property, and sent thousands to bomb shelters. They threaten to plunge the entire region into conflict. There is a way to shoot these missiles out of the sky, limiting the danger to innocents and mitigating the serious threat of one of the region’s most dangerous terrorist groups. The U.S. Army and Israeli Defense Ministry have a joint program that has developed a high-energy laser that can do the job, but they have been slow to deploy the system. The United States should ready the system for operational use as quickly as possible and make it available to the Israeli Defense Forces.
A Known Threat and a Known Countermeasure
Katyusha multiple rocket launchers were first fielded by the Soviets during World War II. They fire a primitive, short-range unguided rocket that is not very accurate. They have only limited military utility but are perfect for terror. Hezbollah has a vast stockpile of Katyushas.
This threat is not new, and the United States and Israel have been working on countermeasures for over a decade. In 1996, the U.S. Army and the Israeli Ministry of Defense began joint development of a system, the Tactical High Energy Laser (THEL), to defend against the types of rockets Hezbollah is using against Israel today. The Army terminated development of the system in 2006 because of technical complexities and lack of mobility. It wasn’t really ready for the battlefield. There is a “relocatable” version of THEL in development, but funding for the program has been limited. It will not be ready for at least another 18 months. So ten years after development began, there is still no defensive system in the field to protect America and its allies from terrorist rocket attacks.
The real tragedy is that the THEL works. At the White Sands Missile Range, THEL intercepted Katyusha rockets 46 times, as well as artillery and mortar projectiles, in single, multiple, and surprise engagements. The basic technology is proven and has been in development for 20 years.
This is a clear case of the perfect being the enemy of the good. If the U.S. Army continues development of THEL and deploys it, even with imperfections, Israel would have a defensive capability in place in the near future, when it is desperately needed.
The Promise of Directed Energy
Directed energy weapons demonstrate tremendous potential against all kinds of mortar, artillery, rocket, aircraft, and missile threats. Directed energy can be used against short-range threats like the Katyusha rockets being fired at Israel and against ballistic missiles in their boost phase. Putting a system in the field now will not only help Israel, but also provide invaluable operational experience on how to use these systems.
Congress should provide emergency supplemental funding to rush THEL into production. The Administration should direct the Army to accelerate the program as rapidly as possible.

Either fight to deploy...or get out of the way!!!
Is that laser beam actually as wide as that mirror ?
Meet the future of CIWS. This is why I believe little additional money has been put into Phalanx. Mach 3 ASCMs require a more immediate response.
Just for perspective, the whole concept of directed energy, indeed all historical and contemporary weaponry, is to take energy from a source, launch and deliver it accurately, then obliterate the crap outta the target in a paroxysm of 1/2 mv^2 (or heat) violence. Controlled energy launch here...to uncontrolled energy arrival there.
There is another kind of weapon that is spiritual and is unknown by national armies. This is another kind of violence and delivers another kind of energy.
I agree with the post. The Middle East might be a good place to test and improve such a weapon.
I wonder how good it is at swatting houseflies. I could use a new swatter.
Interesting. Thanks for posting.
While directed energy weapons might solve many issues it can never be the technological cure all its supporters claim it to be.
Always remember the final battlefield and the only one that counts is in the human mind. “Winning hearts and minds”, to quote a saying from Vietnam, is the real key to understanding World War IV.
For those who are trying to stand on the sidelines (they just want rice in their rice bowls) you try to win their hearts. Get them to understand it is in their best interest to support.
For those who are carrying a gun and are killing your troops (they are true believers of the cause) you try to win their minds. Get them to understand that their individual survival means giving up the true belief. You do this by killing them every chance you get. The survivors, their leadership, will get the message and either stop trying to kill you (a truce), convert (peace) or get exterminated (peace).
Unfortunately this has been the history of armed conflict. And man has not evolved sufficiently to change this harsh reality.
The fixed installation design could easily be stationed in three locations in Israel, North, South and Middle to provide total coverage. Being such a ridiculously small country, a mobile system is a complete waste of money. Fixed is the way to go for them.
...or even to populated sites.
Scrubbers solve that. And better "toxic chemicals" (can you say gasoline truck?) rolling around their streets in tankers than Katyusha's raining down on their houses and industry...
The Deuterium Flouride and combustion by-products are not serious issues. Residue removal maintenance issues in an operationally deployed system are easily manageable.
The real issue was keeping the mirrors cool. And the fixed installation allowed for an effective approach to implement a solution. One that is not easily translatable to a mobile platform.
Deploy it now. Its better than nothing.
Yes.
MTHEL testbed beam director during laser firing. In this infrared photo, the MTHEL testbed high-energy laser beam can be seen as it is projected by the beam director at a Katyusha rocket in flight.
How about swamping the defense? Can this handle a large volume of fire or will it overheat?
As far as swamping the defense, that is basically a non-winner. Unlike ballistic interceptors. The rate of fire, azimuth, slewing across the horizon are all pretty impressive.
It can even nail inbound artillery shells...
"As the nation's only laser weapon, the THEL testbed has shot down a variety of threats since 2000, showing its versatility by destroying about three dozen targets, ranging from Katyusha rockets to artillery shells and large-caliber rockets, and now mortar threats as well."
Here is a depiction of the fixed installation:
Just wondering if you could elaborate.
MOVE 'ZOT'. FOR GREAT JUSTICE.
Most impressive.
....
Not ZOTs!
That is the province of the Higher Powers...
That's okay. "Dwell time" is the nomenclature of choice in the biz. All are just verbal abbreviations to express this idea: Keep the beam on target sufficiently long for destruction. This dwell-time can vary based on target "hardness" or distance issues. Hence, the system has to be able to ascertain when the target either disintegrates or is sufficiently damaged as to permit transition to other targets. Thus in theory, as you surmise, rate-of-kill is limited by the length of that required dwell time. Most effective exposures have been extremely short in duration to have the destructive success, however.
Harbor Freight Co. has a battery-powered, racquet-shaped bug zapper (1500 volts) that my wife really likes for the occasional bug that sneaks in, on sale for $2.99.
I like the sound wave weapons that cause instant loss of bowel control. Let's see those deployed against the muzzies!!
Later.
And who or what would prevent the excremists from polishing their rockets to mirror finish to deflect away most of the laser energy? It is very cheap, too, in comparison with THEL. With shells and mortars it is more tricky as powder gases leave their residue.
Because it doesn't work. This has been tested. It fails because there is too much infrared absorption and "shock kill" destroying the booster structural integrity. This countermeasure was always cavalierly postulated by the bozos at the FAS, Federation of American Scientists, a liberal anti-defense unthink tank (with few real scientists) which the MSM relied on to oppose SDI. Surprising they never admitted when they were debunked.
It is very cheap, too, in comparison with THEL.
Not since it doesn't work.
With shells and mortars it is more tricky as powder gases leave their residue.
Doesn't work for those reasons...and the above. Infrared absorption can't be deflected with mirror finish.
There are infrared/visual mirrors in the lab, and so there are the mirror materials, some of very high reflectivity. IR and visible light lasers have such mirrors as their parts, so right there one has all the necessary coating materials - no need to re-invent the wheel.
An indoor bug zapper?
Some very interesting physics going on there no doubt.
Concerning the FAS - IMHO There is no such thing as Liberal Scientists. There are in fact Liberal Political Scientists.
Laser beam diverges. Beam energy density on the target is much less than on the laser mirror unless the target is very close, so the heavy cooling on the target might not be necessary. And as for increased dwell time - these lasers work in bursts on the order of one second, maybe two or three.
" == An indoor bug zapper? == "
You betcha! Environmentally benign (except to bugs). Batteries NOT included, but cheap. If you get one, let me know how you like it.

The burst mode makes more sense if you are looking to maximize 'shock kill'. Physical affects are probably slightly similar to a supercavitating underwater torpedo traveling through an underwater thermal break. Temperature and pressure differentials. Yes the beam energy at the primary mirror is going to be greater then the applied target beam energy. The main question would be, how much energy loss per distance, and that my friend is probably heavily classified. Would also be affected by atmospheric conditions.
Well, small lasers [easier to collimate] in rangefinders have beam divergence in the range of 0.5 millirad [aka MIL from mil-dot scope]. Assume the same here and you will not be far off. Thus at 5 km distance the beam would be something like 3 m in diameter. If at the source it is about 1 meter wide, then energy density at 5 km is 1/9th of that on the laser mirror.
Richard Saunders, et al., Lasers Operation, Equipment, Application, and Design (New York, NY. McGraw-Hill Book Company, 1980), p. 10. For reference, The lower limit on the divergence (or spreading) of a laser beam is a function of the wavelength of the light and the size of the aperture. And divergence can be reduced by either shifting to shorter wavelengths (higher frequencies) or increasing the size of the aperture. Lasers whose divergence is reduced to the theoretical minimum are categorized as diffraction limited.
Hints of the character of the generally unseen forces controlling/manipulating areas like the Middle East are contained in the bible, specifically in the book of Daniel where the Prince of Persia and of Greece are mentioned. Concepts of this hidden warfare engaged by some few are not limited to biblical times. See the book "Rees Howells, Intercessor" - Norman Grubb, and "Radiant Glory" - Martha Wing Robinson. I am presuming there are others, only these two come to mind as I have read them.
Chief attributes of such warriors are love for the Savior (yes, Jesus Christ), very little remaining self-life, love for fellow man and an unflagging pursuit of the goal: destruction of evil and an ushering in of the Millenial Kingdom. None of this requires the carnage rampant with Islam.
This type of warfare is not engaged by the many, as so few are willing to lay their own lives down to the extent necessary. As you may imagine, such a stripping is not popular.
Of course, no national armies push this offense. We fight in the natural realm, since this is all we know.
Oh, you could also read Ephesians 6: 10 - 18, especially ver 12.
Sufficient elaboration?
Yep...and I agree 1000%.
It does. In solid-state laser assemblies, they refer to them as "fiber" lasers. Bundling a number together to produce a combined beam. It also helps with beam divergence. In a way, its analogous to the "Gatling Gun" approach. Which allows sustained rates of fire which would otherwise be unmanageable...allowing the unused barrels to cool.
Just my 2 cents. Thanks for the info.
You're welcome.

Northrop Grumman Unveils Skyguard Laser Defense System
Defense Daily, July 25, 2006
By Ann RooseveltNorthrop Grumman [NOC] this week unveiled Skyguard, the next generation laser-based air defense system that could provide speed-of-light defense for deployed forces, military installations, critical civilian airports, harbors, or industry.
Denied success on the ground, terrorists have taken to the air. Rockets and mortars rain down on U.S. troops and allies in Iraq. The threats are inexpensive, easily available, and even homemade versions have attacked civilian populations, for example, in Israel. Counter fire has often caused civilian casualties, which escalates conflict.
A single Skyguard system can generate a protective shield of about 10 kilometers in diameter, company officials said at a briefing at their Arlington, Va. offices on Wednesday. It can detect, track and destroy--at the speed of light--single or multiple threats from short-range ballistic missiles, short-and long-range rockets, artillery shells, mortars, cruise missiles, unmanned aerial vehicles, anti-tank guided missiles and man-portable (MANPADs) threats.
"We believe it could be produced in about 18 months," Dan Wildt, director of business development for Directed Energy Systems at Northrop Grumman's Space Technology unit, said. The initial system would likely cost around $150 million to $200 million, while orders for multiple systems could drop the price to around $25 million per copy. It costs about $1,000 a shot, basically the recurring cost of the chemicals.
Northrop Grumman's laser expertise dates back to the 1960s. Skyguard is derived from the successful Tactical High Energy Laser (THEL) Advanced Concept Technology Demonstration test bed developed by Northrop Grumman for the U.S. Army and the Israel Ministry of Defense in light of the Katyusha rocket threat to northern Israel.
"We never turned on the laser and failed to hit the target," Wildt said.
THEL claims 46 successful kills against single, multiple and surprise Katyusha rocket attacks, artillery projectiles, large caliber rockets and mortars.
Skyguard has next generation laser, power and computing capability in a platform that is a factor of four times smaller than THEL, which is based on 1980s technology, Wildt said.
"We never turned on the laser and failed to hit the target," Wildt said.
God bless you and prosper you then as you endeavor to do His will in every way.

Gort will take care of the Hezbollah!
Actually, wasn't that Klaatu, Barada, niktu?
No wonder Gort wasn't answering my call! Thanks! (LOL)
I'm sure he was, and of all types!
Like R. Lee Ermey no doubt...
Thanks for the link. Very interesting.
