Samuel J. Seymour was present at Ford’s Theatre the night — April 14, 1865 — that President Lincoln was assassinated by John Wilkes Booth. Seymour ended up being the longest survivor witness of this tragically historic moment, living long enough to be interviewed on television. On on February 9, 1956, he appeared on an episode of the CBS show I’ve Got a Secret at the age of 95 — Seymour incorrectly states he is 96, but when you’re that old, you’re allowed to say whatever you want — in which celebrity panelists try to determine each contestant’s secret by asking a series of “yes-or-no” questions.
The panelists — Bill Cullen, Jayne Meadows, Henry Morgan, and Lucille Ball — figure out Seymour’s secret without much difficulty, allowing host Garry Moore to summarize Seymour’s memory of that fateful evening. Moore explains that, at the age of five, Seymour did not understand that the president was shot, and therefore was only concerned about the well-being of the man who fell from the balcony. Seymour died shortly after on April 12 of that same year. Watch the video below.
At a recent event, Russian Defense Minister Sergei Shoigu said that a division of troops would be stationed in Chukotka, Russia’s far-east region, just slightly more than 50 miles from Alaska.
“There are plans to form a coastal defense division in 2018 on the Chukotka operational direction,” said Shoigu.
He said that the deployment was “to ensure control of the closed sea zones of the Kuril Islands and the Bering Strait, cover the routes of Pacific Fleet forces’ deployment in the Far Eastern and Northern sea zones, and increase the combat viability of naval strategic nuclear forces.”
The Army fired an interceptor missile designed to protect forces on the ground by destroying incoming enemy fire from artillery, rockets, mortars, cruise missiles and even drones and aircraft, service officials explained.
The successful live-fire test, which took place at White Sands Missile Range N.M., demonstrated the ability of a new Army Multi-Mission Launcher to fire a weapon called the Miniature Hit-to-Kill missile. It is called “hit-to-kill” because it is what’s called a kinetic energy weapon with no explosive. Rather, the interceptor uses speed and the impact of a collision to destroy approaching targets, Army officials explained.
The idea is to give Soldiers deployed on a Forward Operating Base the opportunity to defend themselves from attacking enemy fire. The MML is configured to fire many different kinds of weapons; they launcher recently conducted live fire exercises with an AIM-9X Sidewinder missile and an AGM-114 Hellfire missile. These MML is engineered to fire these missiles which, typically, are fired from the air. The AIM-9X is primarily an air-to-air weapon and the Hellfire is known for its air-to-ground attack ability.
The Multi-Mission Launcher, or MML, is a truck-mounted weapon used as part of a Soldier protection system called Integrated Fire Protection Capability – Inc. 2. The system, which uses a Sentinel radar and fire control technology to identify and destroy approaching enemy fire and protect forward-deployed forces. The technology uses a command and control system called Integrated Air and Missile Defense Battle Command System, or IBCS.
The MML launcher can rotate 360 degrees and elevate from 0-90 degrees in order to identify and knock out approaching fire from any direction or angle.
“The MML consists of fifteen tubes, each of which can hold either a single large interceptor or multiple smaller interceptors. Developed using an open systems architecture, the launcher will interface to the IBCS Engagement Operations Center to support and coordinate target engagements,” an Army statement said.
As tensions with North Korea escalate in the wake of that country’s sixth nuclear test, the United States is also flexing its military muscle.
One of the primary systems being spun up is the B-1B Lancer.
This Cold War-era bomber is a very powerful system – it carries 84 500-pound bombs internally, and also could carry another 44 externally. Should Russia try to take the Baltic states of Estonia, Latvia, and Lithuania, the Lancer is very likely to take out their ground forces with weapons like the CBU-97.
That sort of deadly precision can also apply to Kim Jong Un’s massed artillery. The preferred weapon in this case would be more along the lines of the GBU-31 Joint Direct Attack Munition. Each B-1 can carry up to 24 of these weapons, enabling it to knock out hardened artillery bunkers. The B-1B can also use smaller GBU-38 JDAMs, based on the Mk 82 bomb, to hit other positions.
According to an Air Force fact sheet, the B-1B Lancer entered service in 1986. It has a top speed of Mach 1.2 at sea level, and “intercontinental” range. Among the other weapons it can carry are the AGM-158 Joint Air-to-Surface Standoff Missile. A Navy release noted that the B-1B recently tested an anti-ship version of the JASSM.
You can see the B-1B carry out one of its recent training missions over Korea in the video below. Note the heavy F-15 escort. These are valuable bombers – and only 66 are in the active Air Force inventory.
With the capability to carry a variety of weapons such as air-to-air missiles, precision guided bombs, and a 25mm machine gun that can fire up to 3,600 rounds per minute, the Harrier is the Marine Corps’ top choice when they need close air support where airfields are hard to come by.
“On my first flight, my instructor told me it was going to be like riding a dragon,” says Marine Capt. Brady Cummins during an interview. “He was definitely telling the truth.”
The AV-8B Harrier II was the first Marine tactical aircraft to arrive in the Persian Gulf for Operation Desert Storm in the early ’90s.
According to Boeing, the U.S. took 86 Harriers, flew 3,380 combat sorties and totaled 4,112 hours of combat flight time during the 42-day war.

These aerial marvels are known for their fixed-wing vertical short takeoff and landing — also known as “V/STOL” — which makes the Harrier one of the most maneuverable in service. The Harrier’s engines produce 23,000 pounds of thrust, allowing the aircraft to hover like a helicopter or launch forward at near-supersonic speeds.
At only 47 feet long and weighing 15,000 pounds when empty, this combat jet is approximately half the size of other modern fighter jets.
Pirates have returned to the waters off Somalia, but the spike in attacks on commercial shipping does not yet constitute a trend, senior U.S. officials said Sunday.
The attacks follow about a five-year respite for the region, where piracy had grown to crisis proportions during the 2010-2012 period, drawing the navies of the United States and other nations into a lengthy campaign against the pirates.
U.S. Defense Secretary Jim Mattis told reporters at a military base in the African nation of Djibouti, near the Gulf of Aden, that even if the piracy problem persists, he would not expect it to require significant involvement by the U.S. military.
At a news conference with Mattis, the commander of U.S. Africa Command said there have been about six pirate attacks on vulnerable commercial ships in the past several weeks.
“We’re not ready to say there’s a trend there yet,” Marine Gen. Thomas Waldhauser said, adding that he views the spurt of attacks as a response to the effects of drought and famine on the Horn of Africa.
He said he was focused on ensuring that the commercial shipping industry, which tightened security procedures in response to the earlier piracy crisis, has not become complacent.
Navy Capt. Richard A. Rodriguez, chief of staff for a specially designated U.S. military task force based in Djibouti, said piracy “certainly has increased” in recent weeks. But he said countering it is not a mission for his troops, who are focused on counterterrorism in the Horn of Africa and developing the capacities of national armies in Somalia and elsewhere in the region.
Several other countries have a military presence on or near that U.S. site, including France, Italy, Germany and Japan. This reflects Djibouti’s strategic location at the nexus of the Red Sea and the Gulf of Aden.
Mattis made a point of spending several hours in Djibouti during a weeklong trip that has otherwise focused on the Mideast. As a measure of his concern for nurturing relations with the Djiboutian government, he flew four hours from Doha, Qatar, and then flew right back.
At his news conference, Mattis praised Djibouti for having offered U.S. access to Camp Lemonnier shortly after the Sept. 11 attacks.
“They have been with us every day and every month and every year since,” he said.
The U.S. rotates a range of forces through Lemonnier and flies drone aircraft from a separate airfield in the former French colony. U.S. special operations commandos are based at Lemonnier for counterterrorism missions in Somalia and elsewhere in the region.
During Mattis’ visit, elements of the 24th Marine Expeditionary Unit, including V-22 Osprey aircraft and Harrier attack jets were visible on Lemonnier’s airfield.
The U.S. military presence has grown substantially in recent years, as reflected by construction of a new headquarters building, gym, enlisted barracks and other expanded infrastructure.
Djibouti has a highly prized port on the Gulf of Aden. The country is sandwiched between Somalia and Eritrea, and also shares a border with Ethiopia.
Mattis is using the early months as defense secretary to renew or strengthen relations with key defense allies and partners such as Djibouti, whose location makes it a strategic link in the network of overseas U.S. military bases.
Djibouti took on added importance to the U.S. military after 9/11, in part as a means of tracking and intercepting al-Qaida militants fleeing Afghanistan after the U.S. invaded that country in October 2001.
The U.S. has a long-term agreement with Djibouti for hosting American forces; that pact was renewed in 2014.
Over the past week Mattis has met with leaders in Saudi Arabia, Israel, Egypt and Qatar.
Dr. Randy Lovelace was a Harvard-educated flight surgeon with the U.S. Army who became a pioneer in aeromedicine and aviation physiology — particularly with the issues surrounding high-altitude flight. He was instrumental in developing the first oxygen masks and other adaptive equipment that allowed aviators to survive in low space.
In 1940 Lovelace met Jackie Cochran, a record-holding air racer who petitioned First Lady Eleanor Roosevelt to use women as pilots on the homefront in a variety of non-combat missions. That idea turned into the Women’s Airforce Service Pilots, better known as “WASPs,” during World War II. These female aviators served in crucial roles — test pilots, ferry pilots and maintenance check pilots — that freed up more male pilots to fight the battles that were raging across the globe. A few years later Cochran, by virtue of her friendship with Chuck Yeager, became the first woman to break the sound barrier. After that, she became the first woman to land an airplane on an aircraft carrier.
So when NASA started fielding candidates for what would eventually become the Mercury 7 astronauts, Lovelace and Cochran started a parallel effort that mirrored NASA’s rigorous testing — doable because Lovelace was a key player in designing the official program for the space agency. Along the way they asked another record-breaking female aviator, Jerrie Cobb, to join the effort. The three of them scrubbed the veteran WASP community — a population of over 700 pilots — and came up with 13 qualified females willing and able to go through their NASA-like testing.
Cobb dubbed the group “Fellow Lady Astronaut Trainees” or “FLATs.” The 13 went through a series of stressful evaluations designed to see if they could hold up under the conditions in space. Ice water was injected into their ears to induce vertigo. Painful electric shocks were administered to test reflexes. Weighted stationary bicycles were used to rapidly push candidates to exhaustion. And that was just Phase I of the testing.
All 13 of the women passed Phase I, but because of family and job commitments, only three of them — Jerrie Cobb, Rhea Hurrle, and Wally Funk — were able to travel to Oklahoma City for Phase II. Phase II involved psychological evaluations — including one that had them sit in an isolation tank for an extended period. All three woman passed.
After Jerrie Cobb passed Phase III, which included actual flights in military jet aircraft, the rest of the FLATs were invited to follow suit. But before they could gather at Naval Air Station Pensacola, the designated location, U.S. Navy officials at the base sent a telegram to the candidates that informed them that support for the project had been withdrawn because the request hadn’t come through NASA channels.
That ruling infuriated Cobb, and in 1962 she flew to Washington, D.C., to petition lawmakers to make the FLATs program an official part of NASA. Her efforts led to Rep. Victor Anfuso, R-NY, convening public hearings before a special Subcommittee of the House Committee on Science and Astronautics. Cobb’s testimony introduced gender discrimination into the Hill’s conversation well before the Civil Right Act of 1964 made it illegal.
But the way forward for the FLATs was plagued by infighting among the principals more than unresponsive congressmen. Jackie Cochran, of all people, sensing she was losing clout among her peers, testified that setting up a special program to help women would hurt NASA. Cochran’s negative view was multiplied by the opinions of a handful of Mercury 7 astronauts, including John Glenn, who said that the absence of women in the program was “a fact of our social order.”
Glenn also pointed out that astronaut candidates were required to be graduates of one of the military’s test pilot schools, something women were not qualified to apply for in 1962, and NASA had already indicated it had no desire to waive the requirement by giving females credit for the massive amount of flight experience they had — in some cases many more flight hours than the Mercury 7 selectees. Although some in congress were sympathetic to the FLATs’ plight, Cobb’s Capitol Hill visit didn’t result in any meaningful support.
Soviet cosmonaut Valentina Tereshkova became the first woman in space on June 16, 1963. In response, “Life” magazine published an article criticizing NASA and American decision makers. The article included photographs of all 13 FLATs, which made the entire group of women public for the first time.
NASA did not select any female astronaut candidates until 1978. Astronaut Sally Ride became the first American woman in space in 1983, and in 1995 Eileen Collins was the first woman to pilot the Space Shuttle. At Collins’ invitation, seven of the surviving FLATs attended her launch.
In 1995, while working on a film adaptation of the FLATs’ story, Hollywood producer James Cross coined the label “Mercury 13” for the FLATs. (Look for that title in a theater near you in the years to come.)
That’s just one name out of thousands that airmen and their families submitted for the B-21 Long Range Strike Bomber, whose official name was unveiled as the B-21 Raider on Monday at the Air Force Association’s annual Air, Space Cyber Conference.
The moniker comes from “Doolittle Raiders,” the World War II-era bomb crews who launched morale-boosting strikes on Tokyo after the Japanese attack at Pearl Harbor. (At this week’s Air Force Association conference, Air Force Secretary Deborah Lee James handed the mic to Richard E. Cole, a 101-year-old retired lieutenant colonel and last surviving “Doolittle Raider,” to announce the name of the new bomber.)
Air Force Global Strike Command in March launched a website asking airmen, their family members and retirees to suggest names for the next-generation aircraft. And airmen got creative, slightly goofy and sometimes a bit clumsy with their suggestions.
John Glenn, the first American to orbit the Earth, a former US senator, and former Marine aviator who saw combat in World War II and Korea, has died at 95.
Glenn is known for a number of accolades throughout his life of service, from the military to the astronaut program and eventually, into politics. So it’s worth looking back on his entry into politics, when he first ran for office against an incumbent named Howard Metzenbaum.
In 1974, Glenn’s military record offered an opening for criticism by his opponent, who was mindful of Americans’ anti-war fervor during the Vietnam War. Metzenbaum began calling him “Col. Glenn” to highlight his time in the Marine Corps, and later told him that he “had never met a payroll,” which Glenn perceived as being told that his military record and service with NASA didn’t qualify as “having held a job.”
His response during the debate was remarkable, and at the end of it, he received more than 20 seconds of sustained applause, according to PBS. Here’s what he said:
“I spent 23 years in the United States Marine Corps. I lived through two wars. I flew 149 missions. I was in the space program. It wasn’t my checkbook, it was my life that was on the line.
You go with me as I did out to a veterans’ hospital and look those men with their mangled bodies in the eye and tell them that they didn’t hold a job. You go with me to any Gold Star mother and you look her in the eye and you tell her that her son did not hold a job. You go to Arlington National Cemetery — where I have more friends than I’d like to remember — and you think about this nation, and you tell me that those people didn’t have a job.
I tell you, Howard Metzenbaum, you should be on your knees every day of your life thanking God that there were some men, some men, who held a job. And they required a dedication to purpose, a love of country, and a dedication to duty that was more important than life itself.
And their self-sacrifice is what has made this nation possible.
I have held a job, Howard.”
Glenn went on to defeat Metzenbaum in the primary and win the general election. He served in the Senate from 1974 to 1999. His speech was also used to motivate a group of US Marines before they went into combat in Marjah, Afghanistan in 2010.
Since the earliest days, humans have employed bioweapons both invisible and nefarious: killers on two legs, four, six, eight – and plenty with no legs at all. All of these agents of biological warfare, fresh with the fury of nature, have taken their turns inspiring terror in enemy forces, and turning the tide of unwinnable battles.
In the modern day, just as many bio-weapons have been employed by terrorists and monsters, “humans” who barely qualify for the title. Yes, history is filled with deadly organisms – viruses, bacteria, harmless looking flowers, and even playful sea mammals. All have seen their fair share of battle, and some were admittedly pretty awesome. But if this otherwise terrifying bioweapons list anything to teach, it may be that nature’s most brutal creations are those dogs of war called “man.”
“This allows the aircraft to identify a threat and actively prosecute that threat through avoidance, deception or jamming techniques,” Mike Gibbons, Vice President of the Boeing F-15 program, told Scout Warrior in an interview a few months ago.
These updated EW capabilities replace the Tactical Electronic Warfare Suite, which has been used since the 1980s, not long after the F-15 first deployed. The service plans to operate the fleet until the mid-2040’s, so an overhaul of the Eagle’s electronic systems helps maintain U.S. air supremacy, the contract announcement said.
Boeing won the initial contract for the EPAWSS project last year and hired BAE Systems as the primary subcontractor.
Overall, the US Air Force is vigorously upgrading the 1980s-era F-15 fighter by giving new weapons and sensors in the hope of maintaining air-to-air superiority over the Chinese J-10 equivalent.
The multi-pronged effort not only includes the current addition of electronic warfare technology but also extends to super-fast high-speed computers, infrared search and track enemy targeting systems, increased networking ability and upgraded weapons-firing capability, Air Force and Boeing officials said.
“The Air Force plans to keep the F-15 fleet in service until the mid-2040’s. Many of the F-15 systems date back to the 1970’s and must be upgraded if the aircraft is to remain operationally effective. Various upgrades will be complete as early as 2021 for the F-15C AESA (Active Electronically Scanned Array) radar and as late as 2032 for the various EW (electronic warfare) upgrades,” Air Force spokesman Maj. Rob Leese told Scout Warrior a few months ago.
The Air Force currently operates roughly 400 F-15C, D and E variants. A key impetus for the upgrade was well articulate in a Congressional report on the US and China in 2014. (US-China Economic and Security Review Commission —www.uscc.gov). Among other things, the report cited rapid Chinese technological progress and explained that the US margin of superiority has massively decreased since the 1980s.
As an example, the report said that in the 1980s, the US F-15 was vastly superior to the Chinese equivalent – the J-10. However, Chinese technical advances in recent years have considerably narrowed that gap to the point where the Chinese J-10 is now roughly comparable to the US F-15, the report explained.
Air Force and Boeing developers maintain that ongoing upgrades to the F-15 will ensure that this equivalence is not the case and that, instead, they will ensure the superiority of the F-15.
Among the upgrades is an ongoing effort to equip the F-15 with the fastest jet-computer processer in the world, called the Advanced Display Core Processor, or ADCPII.
“It is capable of processing 87 billion instructions per second of computing throughput, translating into faster and more reliable mission processing capability for an aircrew,” Boeing spokesman Randy Jackson told Scout Warrior.
High tech targeting and tracking technology is also being integrated onto the F-15, Gibbons added. This includes the addition of a passive long-range sensor called Infrared Search and Track, or IRST.
The technology is also being engineered into the Navy F-18 Super Hornet. The technology can detect the heat signature, often called infrared emissions, of enemy aircraft.
“The system can simultaneously track multiple targets and provide a highly effective air-to-air targeting capability, even when encountering advanced threats equipped with radar-jamming technology,” Navy officials said.
IRST also provides an alternate air-to-air targeting system in a high threat electronic attack environment, Navy, Air Force and industry developers said.
The F-15 is also being engineered for additional speed and range, along with weapons-firing ability. The weapons-carrying ability is being increased from 8 up to 16 weapons; this includes an ability to fire an AIM-9x or AIM-120 missile. In addition, upgrades to the aircraft include adding an increased ability to integrate or accommodate new emerging weapons systems as they become available. This is being done through both hardware and software-oriented “open standards” IP protocol and architecture.
The aircraft is also getting a “fly-by-wire” automated flight control system.
“Fly by wire means when the pilot provides the input – straight to a computer than then determines how to have the aircraft perform the way it wants – provides electrical signals for the more quickly and more safely move from point to point as opposed to using a mechanical controls stick,” Gibbons explained.
Along with these weapons upgrades and other modifications, the F-15 is also getting upgrades to the pilot’s digital helmet and some radar signature reducing, or stealthy characteristics.
However, at the same time, the F-15 is not a stealthy aircraft and is expected to be used in combat environments in what is called “less contested” environments where the Air Force already has a margin of air superiority over advanced enemy air defenses.
For this reason, the F-15 will also be increasing networked so as to better support existing 5th-generation platforms such as the F-22 and F-35, Air Force officials said.
The intent of these F-15 upgrades is to effectively perform the missions assigned to the F-15 fleet, which are to support the F-22 in providing air superiority and the F-35 in providing precision attack capabilities, Leese said.
“While these upgrades will not make these aircraft equivalent to 5th generation fighters, they will allow the F-15 to support 5th generation fighters in performing their missions, and will also allow F-15s to assume missions in more permissive environments where capabilities of 5th generation fighters are not required,” Leese added.
Gibbons added that the upgrades to the F-15 will ensure that the fighter aircraft remains superior to its Chinese equivalent.
“The F-15 as a vital platform that still has a capability that cannot be matched in terms of ability to fly high, fly fast, go very far carry a lot. It is an air dominance machine,” Gibbons explained.
For decades, the U.S. military and its private-sector partners have been working toward a technology straight out of science fiction: robotic suits.
And it’s no surprise. Exoskeletons could add to soldiers’ natural strength, letting troops lift seemingly impossible loads and dart across the battlefield at incredible speed.
Currently, the military is exploring creating an Iron Man-like specialized suit through the Tactical Assault Light Operator Suit (TALOS) program. The suit would provide soldiers with enhanced mobility and protection, and it would most likely run on top of an exoskeleton base.
Today’s exoskeletons vary in utility, but they can allow soldiers to carry 17 times more weight than normal and march with significantly less strain on the body. With an XOS 2 suit, for example, a solider can carry 400 pounds but feel the weight of only 23.5.
Although robotic exoskeleton suits have been in development for over 50 years, things really started picking up speed in the 1990s, leading to more and more interest from the U.S military. Now, it’s a clear priority.
As former Air Force Chief of Staff General John Jumper said: “We must give the individual soldier the same capabilities of stealth and standoff that fighter planes have. We must look at the soldier as the system.”
Early 1960s: The Man Amplifier
Throughout the early 1960s, Neil Mizen developed the early stages of the Man Amplifier at Cornell University’s Aeronautical Lab. The suit was intended to have powered gears at the joints to provide additional support and strength.
Although it was hoped that the Amplifier would have military and scientific uses, Mizen could not master the system’s powered gear system, and the suit was never completed. Even so, his research went on to inspire future exoskeleton projects.
1965: The Hardiman Suit
One of the first powered iterations of exoskeletons was General Electric’s 1965 Hardiman Suit, which was co-developed with the U.S. military. The suit built upon the research done for the Man Amplifier.
The Hardiman was intended to lift 1,500 pounds; however, the suit never managed to act as a fully unified machine, and controlling it proved impossible.
Instead, research was focused on one arm of the suit. The arm managed to lift 750 pounds, but it weighed three quarters of a ton alone. The suit was deemed impractical, and the project was eventually abandoned.
1997: The Hybrid Assistive Limb (HAL)
In 1997, the Japanese research firm Cyberdyne started the earliest prototype of the Hybrid Assistive Limb (HAL). The South Korean and U.S. militaries offered to fund the program, but the company wanted to avoid military applications for its technology.
The first prototypes of HAL were created at Tsukuba University with the aim of assisting the disabled and elderly with their daily tasks. The original HAL systems were attached to computers, and the batteries alone weighed 49 pounds.
The HAL 5
In 2013, the fifth-generation HAL prototype, HAL 5, received a global safety certificate for worldwide medical use. It was the first powered exoskeleton to receive this certification.
The HAL 5 is a full-body exoskeleton that weighs a total of 22 pounds. The system functions by sensing bio-signals on the surface of the skin, causing the exoskeleton to mirror the user’s movement. The suit can function for about an hour and a half on a full charge. The suit was used by relief workers during efforts to clean up the partial meltdown of Japan’s Fukushima nuclear power plant, because the suit could allow workers to wear more protective gear and work longer shifts without tiring as quickly.
The Berkeley Lower Extremity Exoskeleton (BLEEX)
The Berkeley Lower Extremity Exoskeleton (BLEEX) entered development in 2000 with a $50 million grant from DARPA. The prototype allowed wearers to carry upward of 200 pounds while feeling no additional weight. The exoskeleton was even capable of traversing rough terrain for extended periods of time.
The BLEEX has been designed so that the legs can be easily removed from the back if the device loses power — thus transforming it back into a standard backpack.
Springtail Exoskeleton Flying Vehicle
In 2001, Trek Aerospace ran its first test of the now-defunct Springtail Exoskeleton Flying Vehicle. The Springtail was considered for military development and even allowed for vertical flight. But ultimately, the project was deemed impractical and never took off.
The Springtail was unique in that it would allow soldiers to fly and hover, effectively taking the role of a personal vertical takeoff and landing (VTOL) vehicle. The Springtail had a maximum speed of 113 miles per hour and could fly for 184 miles and carry a payload of 358 pounds.
Also in 2001, U.S. Army Rangers veteran Monty K. Reed set up North Seattle Robotics Group. The group opened the They Shall Walk non-profit, dedicated to developing LIFESUIT exoskeletons for the disabled.
Reed had a parachute accident while in the military in 1986 that left him with permanent back injuries. During his recovery, Reed became fascinated with the exoskeletons in Robert Heinlein’s novel “Starship Troopers.” The LIFESUIT is in a late stage of development, and it has entered widespread medical trials.
In 2000, Sarcos, an engineering and robotics firm in Utah, began designing the XOS Exoskeleton after receiving a grant from DARPA. DARPA accepted Sarcos’ exoskeleton design in 2006, and production of prototypes began that year.
The XOS had to stay connected to a power source to maintain movement. But the suit performed remarkably within this limitation: The XOS allowed users to lift significantly more weight than they could previously. Its actual-to-perceived-weight ratio was 6:1, meaning that a 180-pound load would feel like only 30 pounds.
A lighter, more efficient XOS
In 2007, the defense giant Raytheon purchased Sarcos. In 2010, Raytheon-Sarcos released the XOS 2. The XOS 2 featured a host of improvements over the XOS.
The XOS 2 suit allows users to lift heavy objects at an actual-to-perceived-weight ratio of 17:1. The suit also required 50% less energy than the XOS, while also weighing 10% less than its predecessor.
The XOS 2 is also touted as being more precise, faster, and more portable than the XOS. The military is considering using the XOS 2 in its TALOS project.
The Human Universal Load Carrier
The Human Universal Load Carrier (HULC) began development in 2000 with Berkeley Bionics, which later changed its name to Ekso Bionics. The HULC was a third-generation exoskeleton system, and it incorporated features from two previous Ekso Bionics prototypes.
The HULC was proved to augment the strength of its wearers, allowing them to lift 200 pounds without impediment. The HULC also lowered the wearer’s metabolic cost, meaning soldiers could march with a load while having a decreased oxygen consumption and heart rate.
The HULC’s Military Applications
In 2009, Ekso Bionics licensed the HULC to Lockheed Martin for research into possible military applications. Lockheed continued its development of the HULC along the same lines as Ekso Bionics, but it increased the functionality of the suit to match the military’s needs.
HULC is multi-terrain operational, supports front and back payloads, and has enough power to last for an eight-hour march before having to be recharged. HULC allows a user to perform deep squats or crawl while wearing it, and it supports upper-body lifting as well. HULC is one of the exoskeletons currently being examined by the military for possible use in its TALOS Iron Man suit.
The X1 Mina — NASA’s Exoskeleton
NASA announced that it was creating an exoskeleton as part of a partnership with the Florida Institute for Human and Machine Cognition. The X1 Mina Exoskeleton will have dual functionality. In space and low-gravity environments, the joints of the suit will be stiffer, providing the astronauts with exercise to combat muscle atrophy.
NASA also envisions that the X1 can be used by paraplegics and others with disabilities to provide support while walking. In this case, the X1’s joints can be loosened, providing support to the wearer without being physically taxing.
The Warrior Web Program — DARPA’s Exoskeleton Of The Future
DARPA began its Warrior Web program, aimed at creating a soft and lightweight under-suit that protects wearers’ joints and helps increase the amount of weight a soldier can easily carry while using less than 100 watts of power. One of the most promising designs has come from the firm Boston Dynamics.
The Warrior Web program has produced small exoskeleton-like clothing designs that are meant to be worn under normal uniforms. The overall goal of the program is to increase the endurance of soldiers by lessening the strain on their muscles.
Over the past 50 years, exoskeletons have gone from an unproven and even slightly fanciful technology to systems with medical and aerospace applications. They are becoming lighter, more energy-efficient, and more flexible — meaning that it is probably just a matter of time before the U.S. develops a practical military version.
When he was just a boy, Jet Li traveled to the United States with the Chinese National Wushu Team. While there, he and his team performed for the American President, then Richard Nixon. It was then that Nixon tried to make the young martial artist his personal bodyguard.
Wushu is the standardized form of Chinese martial arts, created in 1949 to bring all the disparate Chinese arts together. Though relatively young as a sport, the separate forms making up the whole of wushu are much, much older.
Li was only 11 when he met President Nixon. Being selected to represent Chinese wushu practitioners was quite the honor for anyone, let alone an 11-year-old boy — considering an estimated 20 million Chinese people practiced the art form. In 1974, Li was good enough to tour the U.S., a tour that culminated with a performance for the President.
He performed his routine on the White House’s South Lawn as Nixon watched on, standing next to one of Li’s female teammates. After his performance, the young man went to stand next to then-Secretary of State, Henry Kissinger.
Next, he was introduced to the President, who was very impressed with his skills.
Nixon leaned in to Li and said, “Young man, your kung fu is very impressive! How about being my bodyguard when you grow up?”
Li replied, “No, I don’t want to protect any individual. When I grow up, I want to defend my one billion Chinese countrymen!”
The room was stunned into silence and no one knew what to say until Kissinger said aloud, “Heavens, such a young boy and he already speaks like a diplomat!”
The next year, Jet Li began his reign as the national martial arts champion, a title he would hold for five consecutive years.
