“We had no thoughts that this 10-kilowatt would be as successful in doing
that as it has been”
US Army Project Manager for the Laser
program Terry Bauer, commenting on the 6 week military exercise to test the
effectiveness of Boeing's HEL MD HEMTT Mounted Laser
Last year had an interesting development that I’d like to note before
January 2014 closes. In November 2013 for about six (6) weeks, the US Army has
been putting Boeing HEL MD (High Energy Laser Mobile Demonstrator), a Truck
mounted Solid State Laser that rides atop an 8-wheeled, 500-horsepower Oshkosh
HEMTT (Heavy Expanded Mobility Tactical Truck), through 6 weeks of testing as
stated in “Army
Laser weapon KOs Mortar rounds”, published December 13, 2013 10:23 AM PST
by Jonathan Skillings, CNET News.
Now it’s reached up to the point of Army Testing, with its future
potential slowly being realized once it scales up from a 10 kW Laser that’s
good for small short range objects at 5 km away to a 100 kW Laser that can take
down bigger objects further away as noted in “Army’s
New Laser Weapon Can Shoot Down Mortars and Drones”, published Dec 21, 2013
7:00am By Luis Martinez, ABC News.
I took interest as I’d done a blog article on the same system by Boeing,
but back then it was called the HEL TD (High Energy Laser Technology
Demonstrator) as described in my blog article
entitled “Boeing
and the HELTD Direct Energy Weapon - StarShip Troopers Death Star in Revenge of
the Sith”, a sort of prototype, if you may and precursor to the HEL MD.
At the time I’d suggested the need to have an Alternative power Source,
such as a Portable Nuclear Fusion Reactor to power the Laser along with Hydrogen
Fuel Cells in a Range Extender Configuration to drive the Vehicles. Possibly
this may have been done to the HEL TD, which may be the reason Boeing now has
the HEL MD!
This therefore is the further development of Directed Energy Weapons which
has great potential as noted in the article “Boeing
Trucks ahead with 8-wheeling Laser weapon”, published October 6, 2012 12:00
PM PDT by Jonathan Skillings, CNET News. A
project that started back in 2011 and has run up a tab of nearly US$11 million
since then, cheap by US Army standards!
The benefits are obvious:
1.
Reduced need for the US Army and Navy to carry heavy
ordinance rounds by using a Directed Energy Weapon approach that just requires
a lot of Electrical Energy.
2.
Ability to shoot down an enemy at literally the
speed of light
3.
Potential to develop weapons that are both
Lethal and non-lethal in one design i.e. it can both destroy and disable simply
by lowering the beam intensity
4.
Stealth of the weapon, as it leaves no heat
signature due to fact it’s a focused beam of Infrared Light
5.
Portability of design, as with improving Battery
and Generator Technology, it’ll soon reach the point of hand-held variants,
eventually replacing Rifles, Assault Weapons and even sidearms
Boeing’s HEL MD did well –
Portability and stability under Fire are Burning Issues
During that time, it took out 90 objects, mainly 60 mm Mortar Rounds and
Drones. Protecting troops against Mortar rounds is of particular importance to
the US Army, as they are small and fired from shoulder launched or grounds
placed Weapons and are hard to guard against. The idea that the US Army seems
to be aiming for is an automated gantry of portable Mobile Truck Lasers that
can automatically spot and disable Mortars mid-flight, effectively a virtual
shield to protect them as they engage the enemy.
In the case of Mortar Rounds, that takes time as they are moving on a
closed looping trajectory. Thus the HEL MD uses sophisticated Radar Tracking to
predict the path of the Mortar and thus aim the invisible Laser at the Mortar
to deliver the knock-out punch, reducing it from an effective round to a flying
rock.
Ditto too for Drones, which were easier to target as they’re following a
fairly straight line trajectory but may be made of more exotic alloys that
require more intense heat. Also they are moving away from the HEL MD, requiring
the system to be able to ramp up power to account for this, hence the interest
in stepping up the power by a factor of 10 from 10 kW system to a 100 kW
system.
Thus portability of this system is key; expect to see the development of
Jeep mounted versions and eventually Backpack mounted Versions as the US Army
goes Directed Energy Weapon to reduce the cost of making bulky ammunition, all
of which futuristic power packs would replace.
Still there are issues as it relates to their effectiveness under bad
weather conditions. This is also the case with the LAWS (Laser Weapon System)
that was developed by Raytheon for about US$40 million was recently tested by
the US Navy at sea onboard the USS Ponce in April 2013 as stated in “Navy's
New Laser Weapon Blasts Bad Guys From Air, Sea”, published April 8, 2013 By
LUIS MARTINEZ, ABC News.
This is similar to the Centurion System developed by Raytheon in Iraq and
later modified as a system codenamed Phalanx for Destroyers as stated in my blog article
entitled “Telecom
Providers and Raytheon - Star Wars on the high Seas”. And yes, it still
apparently has the same olds problems; it apparently can’t stand seawater and a
rocking ship! More work to be done then Engineers!
Equally of concern too is the Cool Down time of this system, as it has to
cool down for awhile before firing again to avoid overheating, being as it’s a
solid State Laser. Recharging the Laser is also an issue, as in the field, a
portable Generator, possibly a heavy duty Hydrogen Fuel Cell may have to
augment Battery Packs to reduce the Recharge Time after firing a predetermined
number of shots.
Given the glacial pace of development of Directed Energy weapons, expect
another update on this in the next five years, as these issues are not as easy
to solve as they sound. But clearly Directed Energy Weapons, due to their
cost-effectiveness to develop based on the small budgets numbers involved, are
the low-cost future modern Warfare Weapons of choice as noted in “How
the Army’s recent successful Laser test could change the future of warfare”,
