FCS Unmanned Vehicles Complete Preliminary Design Reviews
The UVS Integrated Product Team (IPT) completed the five PDRs ahead of the FCS System-of-Systems (SoS) PDR scheduled for later this spring. The SoS PDR will assess the integration of the program’s individual platforms into a complete SoS architecture and help establish baselines for developing prototypes.
“The FCS One Team and our Army partners have taken a big step toward a successful System of Systems review this spring,” said Gregg Martin, Boeing vice president and FCS program manager.
“Each of these unmanned systems plays a critical role in providing soldiers with greater surveillance, reconnaissance and logistical capabilities to increase their effectiveness and survivability on the battlefield.”
The FCS platforms reviewed in the PDRs were the Multifunctional Utility/Logistics Equipment (MULE) family of vehicles and its Autonomous Navigation System (ANS); the Small Unmanned Ground Vehicle (SUGV); the Class I Unmanned Aerial System (UAS); and the Class IV Unmanned Aerial Vehicle (UAV).
The MULE and ANS reviews were completed in fiscal year 2008 and included all three MULE variants: the MULE-Transport, the MULE-Countermine and the Armed Robotic Vehicle-Assault (Light).
The UVS IPT and partner iRobot conducted the SUGV PDR at the iRobot facility in Bedford, Mass., in October.
“The combined government and industry team has done an excellent job in developing a design that meets our requirements and has produced the supporting evidence needed to make this a successful review,” said Alan Walls, director for Unmanned Vehicle Systems.
“With the completion of this event, we have taken another important step in getting the advanced capability of the SUGV into the hands of our soldiers.”
The UVS IPT and partner Honeywell International conducted the Class I UAS PDR at the Boeing facility in St. Louis in late November.
“I am pleased with the progress we have made in the Class I UAS,” said Glenn Morris, LSI program manager for Class I.
“The system’s laser target designator will provide a tremendous capability to the soldier, and the team did a great job of preparing for this review.”
Finally, the UVS team and Northrop Grumman Corp. Unmanned Systems successfully conducted the Class IV UAV PDR at the Boeing facility in St. Louis in December.
“The Class IV PDR review is the culmination of a great deal of hard work by the team and the whole FCS program,” said Doug Jaspering, LSI team lead for UAV.
“We are in really good shape as we move into the detailed design phase, and fully expect to have our prototypes ready for qualification testing on schedule in fiscal year 2011.”

ASI Chaos Small Robot To Participate In Series Of Exercises
Autonomous Solutions announced that its Chaos small robot will be profiled in a series of exercises at Cobra Gold 2009 in Thailand. The Chaos unit that will be at Cobra Gold was built by ASI for the U.S. Army Tank Automotive Research, Development and Engineering Center (TARDEC), which has made it available for the exercise.
The Chaos robot will be operated by Marines in a series of scenarios in which robotic assistance will be beneficial. Engineers from ASI will be on-hand to provide support and receive feedback on the Chaos platform from operators.
robot-chaos-asi
Examples of these scenarios include route security, cordon and search, casualty extraction and logistical supply.
The Chaos robotic platform is designed to remotely access hazardous areas previously accessible only by foot, thereby reducing risk to personnel.
It is able to navigate over extremely rough, steep, and loose terrain with four independent drive tracks that can continuously change orientation a full 360 degrees.
The unique ability to alter its pitch, roll and yaw enables the Chaos platform to navigate surfaces too uneven for other tracked platforms.
With a high payload capacity and an available manipulator arm with a fifty pound capacity at full reach (72 in), Chaos can perform a variety of functions. Its base weight is low enough that it can be lifted out of a vehicle and deployed by two people.
As a JAUS-compatible platform, the Chaos robot also allows easy addition of a wide variety of sensors and other robotic payloads. Its simple, modular design affords easy field service, maintenance, and repair.
Cobra Gold involves the United States, Thai, Singaporean, Japanese and Indonesian militaries and is meant to improve interoperability, enhance security relationships, and demonstrate U.S. support for humanitarian and security interests in the Pacific.

Merciless robots will fight future wars: researcher
Robots will be armies of the future in a case of science fact catching up to fiction, a researcher told an elite TED gathering on Wednesday.
Peter Singer, who has authored books on the military, warned that while using robots for battle saves lives of military personnel, the move has the potential to exacerbate warfare by having heartless machines do the dirty work.
“We are at a point of revolution in war, like the invention of the atomic bomb,” Singer said.
“What does it mean to go to war with US soldiers whose hardware is made in China and whose software is made in India?”
Singer predicts that US military units will be half machine, half human by 2015.
The US Army already recruits soldiers using a custom war videogame, and some real-world weapon controls copy designs of controllers for popular videogame consoles.
Attack drones and bomb-handling robots are already common in battle zones.
Robots not only have no compassion or mercy, they insulate living soldiers from horrors that humans might be moved to avoid.
“The United States is ahead in military robots, but in technology there is no such thing as a permanent advantage,” Singer said. “You have Russia, China, Pakistan and Iran working on military robots.”
There is a “disturbing” cross between robotics and terrorism, according to Singer, who told of a website that lets visitors detonate improvised explosive devices from home computers.
“You don’t have to convince robots they are going to get 72 virgins when they die to get them to blow themselves up,” Singer said.
Robots also record everything they see with built-in cameras, generating digital video that routinely gets posted online at YouTube in graphic clips that soldiers refer to as “war porn,” according to Singer.
“It turns war into entertainment, sometimes set to music,” Singer said. “The ability to watch more but experience less.”
Robotics designer David Hanson offered hope when it comes to making robots a little more human.
Hanson builds robots that have synthetic flesh faces and read people’s expressions in order to copy expressions.
“The goal here is not just to achieve sentience, but empathy,” Hanson said.
“As machines are more capable of killing, implanting empathy could be the seeds of hope for our future.”
Hanson demonstrated a lifelike robotic bust of late genius Albert Einstein that makes eye contact and mimics people’s expressions.
“I smiled at that thing and jumped out of my skin when it smiled back,” TED curator Chris Anderson quipped. “It’s freaky.”

Synthetic Future
Synthetic Future
After topping off at almost $150 a barrel last July, oil now sells for less than $40. But the price collapse hasn’t altered U.S. Air Force plans to fly its jets on fuel made from coal, natural gas, even animal fat.
“We are still on track to complete certification of all aircraft to fly on synthetic fuels by 2011,” Air Force spokesman Gary Strasburg said. And by 2016, the Air Force wants half of the jet fuel it uses in the United States to be synthetic.
That means about 400 million gallons of fuel made from coal, biomass, natural gas and other nonpetroleum sources. And that may be a problem.
At present, there are no U.S. plants producing enough synthetic fuel to meet more than a fraction of the Air Force needs. Several companies have plans to build plants for turning coal and biomass into synthetic fuel. But the plans were developed when high-priced oil made alternative fuels much more appealing, at least in terms of cost.
In January, the Air Force itself pulled the plug on plans to let a private company build a plant for turning coal into 25,000 barrels of jet fuel a day on federal property at Malmstrom Air Force Base, Mont.
The service declared plans for the plant “not viable,” but cited security concerns, not cost, as the fatal flaw.
Still, the push toward synthetic fuel goes on.
“We have completely certified the B-52 and B-1″ bombers and C-17 cargo planes to fly on synthetic fuel, Strasburg said. In addition, the Air Force has flown F-22 and F-16 fighters, B-2 bombers, KC-135 refueling tankers, C-5 cargo planes and T-38 trainers using a 50-50 mixture of synthetic fuel and standard JP8 military jet fuel.
For testing and certification purposes, the Pentagon’s Defense Energy Support Center has been buying synthetic fuel from South African synfuel producer Sasol.
Ultimately, though, the Air Force wants domestic sources, Strasburg said. The intent is to boost national security by reducing dependence on imported oil.
Synthetic oil becomes competitive when petroleum costs about $60 or $70 a barrel, said Tim Edwards, a senior chemical engineer at the Air Force Research Laboratory’s Propulsion Directorate.
Oil Cost Could Surge Again
Despite the relatively cheap price of oil today, pursuing synthetic fuel “is still a good idea,” Edwards said. As long as the United States continues to import about 70 percent of the oil it burns, “there’s no way to prevent oil from going to $170 a barrel,” he said.
The Air Force hopes its considerable appetite for oil provides the economic foundation for a U.S. synthetic oil industry.
Airlines are beginning to experiment with synthetic fuel, too. And the International Air Transport Association, which represents airlines around the world, has said it wants to replace a quarter of petroleum-based fuels with synthetics by 2025.
In January, the Air Force began buying fuel from Rentech, a Los Angeles-based synfuel company that claims to have the only working Fischer-Tropsch fuel plant in the United States.
For now, Rentech turns natural gas into jet fuel at a rate of 10 barrels - 420 gallons - a day at a plant in Colorado. But the company plans to build a plant in Mississippi that will eventually produce 30,000 barrels of synfuel a day from coal, petroleum coke and biomass. Rentech also plans to produce jet fuel from purely renewable feedstocks.
Rentech makes synfuel using the Fischer-Tropsch process. That involves heating the feedstock - coal, petroleum coke, wood, corn stalks or other biomass - to about 1600 degrees Fahrenheit until it turns to gas.
Various unwanted products in the gas, such as mercury, sulfur and others, are removed, leaving carbon monoxide and hydrogen. The carbon dioxide (C02) and hydrogen are fed into a reactor where a catalyst of iron particles suspended in liquid wax converts them into a form of synthetic fuel called wax.
The synthetic wax is then refined into jet fuel, diesel fuel and similar products using essentially the same process used for turning petroleum into those products.
The process produces a lot of carbon dioxide, and that is a major drawback.
Petroleum-based fuel produces about 27 pounds of CO2 per gallon of fuel. Coal-based synthetic fuel produces about 50 pounds, according to the Natural Resources Defense Council.
Carbon dioxide is produced when the coal is turned into gas. More is created when the finished fuel is burned in an engine. CO2 is the most abundant of the greenhouse gases believed responsible for global warming, and the goal is to produce less of it, not more.
Concerned that liquid fuel made from coal would increase CO2 emissions, Congress passed a law in 2007 to make it illegal for the U.S. government to buy synthetic fuels that emit more greenhouse gases than do fuels already in use.
Rentech and other Fischer-Tropsch advocates offer at least two solutions to the CO2 problem.
Capturing Karbon
One is carbon sequestration. Instead of releasing CO2 into the atmosphere, it is captured and buried underground. Rentech proposes capturing CO2 and piping it to oil fields near the company’s Mississippi plant. Pressurized CO2 would be pumped underground into partially depleted oil wells, where it would push unrecoverable oil into locations where it can be pumped out.
If the carbon dioxide can be captured and then injected into the ground, the fuel produced by the Fischer-Tropsch process can produce 11 percent to 23 percent less CO2 than standard jet fuel, said Julie Dawoodjee, Rentech’s director of investor relations.
Another way to reduce CO2 emissions is to use biomass along with coal to produce liquid fuel.
Biomass is considered to be carbon-neutral. That’s because when it grows, biomass takes carbon dioxide out of the atmosphere. When it is burned as fuel, it is simply returning what had been removed from the air by growing plants. It’s often referred to as carbon recycling.
The U.S. Energy Department estimates there are 1.3 billion tons of biomass available annually - from plants, grain crops and wood residue to animal manure and garbage - that could be turned into liquid fuel.
And it’s not just for airplanes, Edwards said. The Air Force plans eventually to use synthetic fuel to power trucks, generators and heaters, he said.

USAF Seeks Threat Detectors for Satellites
A year and a half after China showed the world it can shoot satellites out of orbit, the U.S. Air Force is taking steps to make future satellites able to detect impending attacks.
And beyond simply seeing it coming, the Air Force wants its satellites equipped with technology that will offer commanders on the ground solid information about who launched the attack.
This effort to make satellites more alert to their surroundings is being called Self-Aware Space Situational Awareness, or SASSA.
The Air Force is reviewing bids by at least two major defense firms to build “suites” of threat-detecting sensors for satellites.
At this point, the SASSA program does not call for adding active countermeasures or other defenses to U.S. satellites.
The Air Force says the sensor suite should include a “visible camera” for spotting and identifying nearby objects, and other sensors for detecting laser attacks and radio frequency jamming, proximity sensors to judge the distance of surrounding objects, and sensors to measure the space environment.
“The final sensor complement is currently being assessed,” the Air Force said in a statement.
Ultimately, different sensors may be placed on different satellites, depending on their missions and the threats that particular satellites are expected to confront, said Todd Citron, director of space superiority and special missions for Boeing in El Segundo, Calif.
Boeing and its defense industry rival Lockheed Martin have submitted proposals for building the sensor suites.
The sensors already exist, Citron said. The task for Boeing and Lockheed is to combine them in a lightweight payload that can plug easily into just about any satellite.
Today, each of the sensors would have to be installed in a satellite separately, and its telemetry carefully woven into the satellite’s communications system, Citron said.
SASSA’s modular approach is intended to produce a cost-effective method for making future satellites “self aware.”
The Air Force Space Superiority Systems Wing said it plans to award two contracts by October. The companies say they expect the contracts to be worth about $30 million.
The Air Force hopes to have sensors and accompanying communications gear ready for launch on satellites as early as 2010 or 2011.
Concern that U.S. satellites, particularly spy satellites, are sitting ducks in space increased in January 2007, when the Chinese military demonstrated its anti-satellite prowess by firing a ground-based ballistic missile to destroy an old Chinese weather satellite 537 miles above the Earth.
However, the Air Force said its push to increase space situational awareness substantially predates the Chinese anti-satellite demonstration. Presidential directives in 1996 and 2006 instruct the U.S. military to “support” space situational awareness for intelligence, military and commercial satellites and for human space flight.
Space situational awareness today is provided mainly by ground-based telescopes and radars that are located around the world. They are used mainly to keep track of objects in space, such as debris from rockets and other satellites, not to warn of imminent attacks.
That’s no longer good enough.
As reliance on space for communications, surveillance, navigation and other purposes increases, so does the ability of potential foes to threaten satellites with jammers, lasers and kinetic kill vehicles.
In a description of the SASSA program earlier this year, the Air Force said it wants to equip satellites to:
■ Provide indications and warning of attack.
■ Identify the source of attacks.
■ Perform battle-damage assessment on adversary space systems.
■ Identify “anomalies” in space, both environmental and man-made.
The satellite’s communications gear is to be able to report threats, attacks and anomalies to the Joint Functional Component Command for Space and the Air Force’s Rapid Attack Identification Detection and Reporting System.
In addition to making satellites self-aware, Boeing is part of an industry team working on a Space Based Space Surveillance system, which is basically a satellite with a 500-pound optical camera for tracking other satellites, space debris and other objects.
“SBSS will revolutionize space situational awareness,” Citron said Ultimately, SBSS will consist of a small constellation of satellites that detect and track objects in space.
Even if U.S. satellites can detect and report threats on their own and be warned of threats by other satellites, it is unclear what they can do about imminent danger.
Adding defensive capabilities to a satellite “is beyond SASSA,” Citron said.
Current U.S. spy satellites and early warning satellites have some ability to protect their optical sensors against laser attacks, and have substantial resistance to jamming, said John Pike, director of GlobalSecurity.org, which monitors defense policy.
“All spacecraft have some maneuvering capability” that they need to make occasional adjustments in their orbits, Pike said.
So if current satellites become aware of imminent threats, they might be able to “run away a little bit. But tactical maneuvering is not what these guys typically do,” he said.
No existing satellites are believed to have “shoot back” capability, but the U.S. military “has definitely looked at shoot back” to protect spy satellites that might be attacked by kinetic kill vehicles in low-Earth orbit, Pike said.

Synthetic Future
After topping off at almost $150 a barrel last July, oil now sells for less than $40. But the price collapse hasn’t altered U.S. Air Force plans to fly its jets on fuel made from coal, natural gas, even animal fat.
“We are still on track to complete certification of all aircraft to fly on synthetic fuels by 2011,” Air Force spokesman Gary Strasburg said. And by 2016, the Air Force wants half of the jet fuel it uses in the United States to be synthetic.
That means about 400 million gallons of fuel made from coal, biomass, natural gas and other nonpetroleum sources. And that may be a problem.
At present, there are no U.S. plants producing enough synthetic fuel to meet more than a fraction of the Air Force needs. Several companies have plans to build plants for turning coal and biomass into synthetic fuel. But the plans were developed when high-priced oil made alternative fuels much more appealing, at least in terms of cost.
In January, the Air Force itself pulled the plug on plans to let a private company build a plant for turning coal into 25,000 barrels of jet fuel a day on federal property at Malmstrom Air Force Base, Mont.
The service declared plans for the plant “not viable,” but cited security concerns, not cost, as the fatal flaw.
Still, the push toward synthetic fuel goes on.
“We have completely certified the B-52 and B-1″ bombers and C-17 cargo planes to fly on synthetic fuel, Strasburg said. In addition, the Air Force has flown F-22 and F-16 fighters, B-2 bombers, KC-135 refueling tankers, C-5 cargo planes and T-38 trainers using a 50-50 mixture of synthetic fuel and standard JP8 military jet fuel.
For testing and certification purposes, the Pentagon’s Defense Energy Support Center has been buying synthetic fuel from South African synfuel producer Sasol.
Ultimately, though, the Air Force wants domestic sources, Strasburg said. The intent is to boost national security by reducing dependence on imported oil.
Synthetic oil becomes competitive when petroleum costs about $60 or $70 a barrel, said Tim Edwards, a senior chemical engineer at the Air Force Research Laboratory’s Propulsion Directorate.
Oil Cost Could Surge Again
Despite the relatively cheap price of oil today, pursuing synthetic fuel “is still a good idea,” Edwards said. As long as the United States continues to import about 70 percent of the oil it burns, “there’s no way to prevent oil from going to $170 a barrel,” he said.
The Air Force hopes its considerable appetite for oil provides the economic foundation for a U.S. synthetic oil industry.
Airlines are beginning to experiment with synthetic fuel, too. And the International Air Transport Association, which represents airlines around the world, has said it wants to replace a quarter of petroleum-based fuels with synthetics by 2025.
In January, the Air Force began buying fuel from Rentech, a Los Angeles-based synfuel company that claims to have the only working Fischer-Tropsch fuel plant in the United States.
For now, Rentech turns natural gas into jet fuel at a rate of 10 barrels - 420 gallons - a day at a plant in Colorado. But the company plans to build a plant in Mississippi that will eventually produce 30,000 barrels of synfuel a day from coal, petroleum coke and biomass. Rentech also plans to produce jet fuel from purely renewable feedstocks.
Rentech makes synfuel using the Fischer-Tropsch process. That involves heating the feedstock - coal, petroleum coke, wood, corn stalks or other biomass - to about 1600 degrees Fahrenheit until it turns to gas.
Various unwanted products in the gas, such as mercury, sulfur and others, are removed, leaving carbon monoxide and hydrogen. The carbon dioxide (C02) and hydrogen are fed into a reactor where a catalyst of iron particles suspended in liquid wax converts them into a form of synthetic fuel called wax.
The synthetic wax is then refined into jet fuel, diesel fuel and similar products using essentially the same process used for turning petroleum into those products.
The process produces a lot of carbon dioxide, and that is a major drawback.
Petroleum-based fuel produces about 27 pounds of CO2 per gallon of fuel. Coal-based synthetic fuel produces about 50 pounds, according to the Natural Resources Defense Council.
Carbon dioxide is produced when the coal is turned into gas. More is created when the finished fuel is burned in an engine. CO2 is the most abundant of the greenhouse gases believed responsible for global warming, and the goal is to produce less of it, not more.
Concerned that liquid fuel made from coal would increase CO2 emissions, Congress passed a law in 2007 to make it illegal for the U.S. government to buy synthetic fuels that emit more greenhouse gases than do fuels already in use.
Rentech and other Fischer-Tropsch advocates offer at least two solutions to the CO2 problem.
Capturing Karbon
One is carbon sequestration. Instead of releasing CO2 into the atmosphere, it is captured and buried underground. Rentech proposes capturing CO2 and piping it to oil fields near the company’s Mississippi plant. Pressurized CO2 would be pumped underground into partially depleted oil wells, where it would push unrecoverable oil into locations where it can be pumped out.
If the carbon dioxide can be captured and then injected into the ground, the fuel produced by the Fischer-Tropsch process can produce 11 percent to 23 percent less CO2 than standard jet fuel, said Julie Dawoodjee, Rentech’s director of investor relations.
Another way to reduce CO2 emissions is to use biomass along with coal to produce liquid fuel.
Biomass is considered to be carbon-neutral. That’s because when it grows, biomass takes carbon dioxide out of the atmosphere. When it is burned as fuel, it is simply returning what had been removed from the air by growing plants. It’s often referred to as carbon recycling.
The U.S. Energy Department estimates there are 1.3 billion tons of biomass available annually - from plants, grain crops and wood residue to animal manure and garbage - that could be turned into liquid fuel.
And it’s not just for airplanes, Edwards said. The Air Force plans eventually to use synthetic fuel to power trucks, generators and heaters, he said.

A year and a half after China showed the world it can shoot satellites out of orbit, the U.S. Air Force is taking steps to make future satellites able to detect impending attacks.
And beyond simply seeing it coming, the Air Force wants its satellites equipped with technology that will offer commanders on the ground solid information about who launched the attack.
This effort to make satellites more alert to their surroundings is being called Self-Aware Space Situational Awareness, or SASSA.
The Air Force is reviewing bids by at least two major defense firms to build “suites” of threat-detecting sensors for satellites.
At this point, the SASSA program does not call for adding active countermeasures or other defenses to U.S. satellites.
The Air Force says the sensor suite should include a “visible camera” for spotting and identifying nearby objects, and other sensors for detecting laser attacks and radio frequency jamming, proximity sensors to judge the distance of surrounding objects, and sensors to measure the space environment.
“The final sensor complement is currently being assessed,” the Air Force said in a statement.
Ultimately, different sensors may be placed on different satellites, depending on their missions and the threats that particular satellites are expected to confront, said Todd Citron, director of space superiority and special missions for Boeing in El Segundo, Calif.
Boeing and its defense industry rival Lockheed Martin have submitted proposals for building the sensor suites.
The sensors already exist, Citron said. The task for Boeing and Lockheed is to combine them in a lightweight payload that can plug easily into just about any satellite.
Today, each of the sensors would have to be installed in a satellite separately, and its telemetry carefully woven into the satellite’s communications system, Citron said.
SASSA’s modular approach is intended to produce a cost-effective method for making future satellites “self aware.”
The Air Force Space Superiority Systems Wing said it plans to award two contracts by October. The companies say they expect the contracts to be worth about $30 million.
The Air Force hopes to have sensors and accompanying communications gear ready for launch on satellites as early as 2010 or 2011.
Concern that U.S. satellites, particularly spy satellites, are sitting ducks in space increased in January 2007, when the Chinese military demonstrated its anti-satellite prowess by firing a ground-based ballistic missile to destroy an old Chinese weather satellite 537 miles above the Earth.
However, the Air Force said its push to increase space situational awareness substantially predates the Chinese anti-satellite demonstration. Presidential directives in 1996 and 2006 instruct the U.S. military to “support” space situational awareness for intelligence, military and commercial satellites and for human space flight.
Space situational awareness today is provided mainly by ground-based telescopes and radars that are located around the world. They are used mainly to keep track of objects in space, such as debris from rockets and other satellites, not to warn of imminent attacks.
That’s no longer good enough.
As reliance on space for communications, surveillance, navigation and other purposes increases, so does the ability of potential foes to threaten satellites with jammers, lasers and kinetic kill vehicles.
In a description of the SASSA program earlier this year, the Air Force said it wants to equip satellites to:
■ Provide indications and warning of attack.
■ Identify the source of attacks.
■ Perform battle-damage assessment on adversary space systems.
■ Identify “anomalies” in space, both environmental and man-made.
The satellite’s communications gear is to be able to report threats, attacks and anomalies to the Joint Functional Component Command for Space and the Air Force’s Rapid Attack Identification Detection and Reporting System.
In addition to making satellites self-aware, Boeing is part of an industry team working on a Space Based Space Surveillance system, which is basically a satellite with a 500-pound optical camera for tracking other satellites, space debris and other objects.
“SBSS will revolutionize space situational awareness,” Citron said Ultimately, SBSS will consist of a small constellation of satellites that detect and track objects in space.
Even if U.S. satellites can detect and report threats on their own and be warned of threats by other satellites, it is unclear what they can do about imminent danger.

Lockheed offers ready-to-go supersoldier exoskeleto
US weaponry globocorp Lockheed is pleased to announce the unveiling of its newly-acquired powered exoskeleton intended to confer superhuman strength and endurance upon US soldiers.
Needless to say, corporate promo vid of the Human Universal Load Carrier (HULC™) is available:
The exoskeleton is based on a design from Berkeley Bionics of California, but Lockheed say they have brought significant pimpage to the basic HULC. The enhanced version is now on show at the Association of the United States’ Army Winter Symposium in Florida.
“With our enhancements to the HULC system, Soldiers will be able to carry loads up to 200 pounds with minimal effort,” according to Lockheed’s Rich Russell.
From the vid, the HULC certainly seems a step forward on Raytheon’s rival XOS mechwarrior suit, which at last report still trails an inconvenient power cable to the nearest wall socket.
Not so the HULC; four pounds of lithium polymer batteries will run the exoskeleton for an hour walking at 3mph, according to Lockheed. Speed marching at up to 7mph reduces this somewhat; a battery-draining “burst” at 10mph is the maximum speed.
The user can hump 200lb with relative ease while marching in a HULC, however, well in excess of even the heaviest combat loads normally carried by modern infantry. There’d be scope to carry a few spare batteries. Even if the machine runs out of juice, Lockheed claims that its reinforcement and shock absorption still helps with load carrying rather than hindering.
There are various optional extras, too. The HULC can be fitted with armour plating, heating or cooling systems, sensors and “other custom attachments”. We particularly liked that last one: our personal request would be a powered gun or missile mount of some kind above the shoulder, linked to a helmet or monocle laser sight.
One does note that remote-controlled gun mounts weighing as little as 55lb are available, able to handle various kinds of normally tripod- or bipod-mounted heavy weapons.
You’d need more power, but that’s on offer. According to the Lockheed spec sheet (pdf) there’s an extended-endurance HULC fitted with a “silent” generator running on JP8 jet fuel. A tankful will run this suit for three days, marching eight hours per day - though presumably at the cost of some payload.
Doubtless other power options could be developed: Lockheed says the HULC needs 250 watts on average.
It’s important to note that the HULC is basically a legs and body system only: there’s no enhancement to the user’s arms, though an over-shoulder frame can be fitted allowing a wearer to hoist heavy objects such as artilery shells with the aid of a lifting strop.
The HULC may not be quite ready for prime time yet. But the military exoskeleton as a concept does seem to be getting to the stage of usefulness, at least in niche situations for specific jobs.
The BigDog petrol packmule, an alternative strategy for helping footsoldiers carry their increasingly heavy loads, may now have a serious rival.
