The Afghan Air Force is scheduled to receive 150 new MD530 F Cayuse Warrior light attack helicopters by 2022.
By this, the total number of MD530 Fs operated by the Afghan National Security and Defense Forces will rise to almost 180.
The US Department of Defense announced on Sept. 5 that it has issued a $1.38 billion contract to MD Helicopters “for procurement of an estimated quantity of 150 MD 530F aircraft and required production support services to include program management, delivery support, pilot training and maintenance,” the Diplomat reported.
The estimated completion date of the contract is 2022.
According to a MD Helicopters press release, the first deliveries under the contract will be 30 MD 530Fs for an estimated $177 million. The first part of the order is expected to be completed by September 2019.
“Mission Equipment for these aircraft will include a ballistic crash worthy fuel system, consisting of a main fuel tank and a 38-gallon Auxiliary Fuel Tank, high capacity landing gear, FN Herstal Weapons Management System, DillonAero Mission Configurable Armament System weapons plank and Fixed-Forward Sighting System, Rohde and Schwarz M3AR Tactical Mission Radio, and FN Herstal .50 caliber HMP 400 Machine Gun Pods and M260 7-shot rocket pods,” MD Helicopters noted in a press statement released on Sept. 13.
Earlier this week, Gen. Phillip A. Stewart, commander of Train, Advise, Assist Command said in an interview with TOLOnews that $7 billion will be spent on the Afghan Air Force over the next four years.
“We expect the Afghan Air Force to be fully professional, sustainable, and capable and independent and that’s our whole goal here,” he said.
Under the new aid package, the number of aircraft owned by the AAF will be doubled in the next four years.
This comes after Major General Abdul Raziq Sherzai, the commander of Kandahar Air Brigade, last week said more military aircraft should be delivered to the hard-pressed Afghan security forces who have been battling insurgent groups in their traditional heartlands in Kandahar and Helmand provinces for weeks.
He said that the Kandahar Air Brigade, despite having inadequate facilities on hand, continue to back the ground forces in their campaign against the militants in Helmand and Kandahar provinces, where in recent months violence dramatically increased following the Taliban’s new attempt to seize control of the strategic province of Helmand in the south and infiltrate neighboring provinces.
The Kandahar Air Brigade that operates under the command of 205 Atal Army Corps has about 20 different types of aircrafts – a figure security officials claim is nothing near what they need to deal with the current scale of security issues that have undermined large swaths of land in the south.
Since being paralyzed almost three decades ago, Dean Juntunen has competed in more than 90 wheelchair marathons, continued snowmobiling and four-wheeling, and taken up kayaking.
Now, Juntunen is taking another significant step. And then another step. And then another.
“Just standing talking to you is interesting,” Juntunen said. “I had not gone from a sitting position to a standing position in 27 years. I got injured in ’91, so just standing is fun. I like just standing up and moving around.”
About 160 veterans are participating in the program at 15 VA Centers across the country. After completing a series of rigorous training sessions, veterans in this study will take the exoskeleton home for use in everyday life.
Juntunen executes a challenging 180-pivot with the aid of VA trainers Cheryl Lasselle (left) and Zach Hodgson.
Participants must meet certain criteria, including bone density. Users should be between about 5-foot-3 and 6-foot-3 and cannot weigh more than 220 pounds.
“Most paralyzed people, if not all, lose bone density,” Juntunen said. “So, you have to pass a bone density scan to qualify for this program. I happen to have unusually good bone density and I’ve been paralyzed for 27 years.”
Juntunen was on active duty when he was injured in between assignments from Malmstrom AFB in Great Falls, Montana, to Wright-Patterson AFB in Dayton, Ohio, when his life changed.
Fell 30 feet, broke spinal cord in two places
An avid hiker and outdoorsman, Juntunen’s life changed when a tree branch gave way and he fell 30 feet to the ground.
“I landed on my back in a fetal position,” said Juntunen, who lives near Mass City in Michigan’s Upper Peninsula. “Spine folded in half, broke five vertebrae, wrecked my spinal cord in two spots.”
“Well, I have a hard time saying no and they strongly asked me to do it. So, I decided, that’s probably going to be fun playing with that robot. I guess I’ll make a bunch of trips to Milwaukee.”
Juntunen, who has an engineering degree, said the hardest part of mastering the robotic device was developing balance.
“One of the hardest things about getting paralyzed is relearning your sense of balance because you can’t feel anything through your butt,” he said. “I’m paralyzed from the base of the rib cage down, so it’s like I’m sitting on a stump all the time.”
Turns and pivots presented challenges, as did going up an incline, he said.
“I liken this to walking on stilts for an able-bodied person because you have to feel the ground through wooden or metal legs. That’s basically what I’m doing in this thing.”
“I don’t really describe this as walking, more like riding the robot,” he said. “The interesting thing is, my brain feels like it’s walking. I’m a complete injury, so I can’t feel anything. My brain has no idea what my legs are doing, but nonetheless, it feels like I’m walking in my head.”
Not all participants are able to sufficiently master the nuances of the 51-pound device to meet the requirements of the study.
Basic training needed to master balance skills
“Some people don’t get past what we call the basic training,” said Joe Berman, Milwaukee VA project manager. “To be eligible to go into the advanced training, you have to be able to master some balance skills and do five continuous steps with assistance within five training sessions. That’s been shown by previous research to be a good predictor of who is going to succeed in passing the advanced skills that we require to take the device home.”
The training sessions at Milwaukee last about two to two-and-a-half hours, usually twice a day. With the aid of certified trainers, Juntunen walked up to a quarter mile, starting with the lightly trafficked tunnel between the main hospital and the Spinal Cord Injury Center.
When Juntunen takes the device home, companions trained to assist will replace the VA trainers.
He eventually progressed to one of the main public entries to the hospital, which had inclines, carpeted areas, and pedestrian traffic.
“The inclines are harder,” Juntunen said. “Here, you’ve got short incline, then flat, then incline, so the transitions are harder. You’re in balance going down and when it flattens out, you have to change where your balance is, so the transition is a little trickier. Coming up is the worst, up the ramps is the hardest. You kind of have to reach behind you with the crutches. It’s more exertion and more difficult on the balance because the robot is always perpendicular to the surface.”
Mastering use of the device in the public space was part of the requirement before Juntunen can take it home.
“In order to take the device home, they need to be able to navigate up and down Americans with Disabilities Act (ADA)-compliant ramps and go through doorways,” said Zach Hodgson, a physical therapist at the Milwaukee VA and part of the certified training team. “Right now, we have three trainers, but at home, he’ll need a companion to walk with him at all times. It’s looking at all those skills we need to get to and then making plans based on how he’s progressing.”
“He’s going to use this device in his home and community so we really get a good idea about how useful these devices are,” Hodgson said.
At home, companions replace the VA trainers to help with the device. In Juntunen’s case, he’s getting help from his kayaking buddies.
“They’ve seen me transferring and stuff,” he said. “They know I can sit and balance, sit on the edge of my kayak before I transfer up to the seat. So, that’s all normal for them.”
After completing training in Milwaukee, Juntunen is scheduled to have another session at a shopping mall in Houghton, Michigan, tentatively followed by another session in the atrium of the Green Bay Packers Hall of Fame.
The Trump administration has agreed to delay joint military exercises with South Korea until after the Pyeongchang Winter Olympics next month, the Pentagon said Jan. 4.
A Pentagon spokesman, Col. Rob Manning, said President Donald Trump agreed to the delay in consultation with South Korean President Moon Jae-in.
“The Department of Defense supports the President’s decision and what is in the best interest of the ROK-U.S. alliance,” Manning said, referring to the U.S. defense treaty with the Republic of Korea.
The decision pushes back a set of annual military exercises known as Foal Eagle, which normally are held between February and April. Foal Eagle is a series of exercises designed to test the readiness of the two countries’ militaries. North Korea routinely objects to such maneuvers as a rehearsal for an invasion.
The Jan. 4 decision came as North Korean leader Kim Jong Un reopened a key cross-border communication channel with South Korea for the first time in nearly two years.
In a tweet early Jan. 4, Trump claimed his tough stance on nuclear weapons on the Korean Peninsula is helping push North Korea and South Korea to talk.
Trump tweeted, “Does anybody really believe that talks and dialogue would be going on between North and South Korea right now if I wasn’t firm, strong, and willing to commit our total ‘might’ against the North.”
Earlier this week, Trump seemed open to the possibility of an inter-Korean dialogue after North Korean leader Kim Jong Un made a rare overture toward South Korea in a New Year’s address. But Trump’s ambassador to the United Nations insisted that talks won’t be meaningful unless the North is getting rid of its nuclear weapons.
The overture about talks came after Trump and Kim traded more bellicose claims about their nuclear weapons.
In his New Year’s address, Kim repeated fiery nuclear threats against the U.S. Kim said he has a “nuclear button” on his office desk and warned that “the whole territory of the U.S. is within the range of our nuclear strike.”
Trump mocked that assertion Tuesday evening, tweeting: “Will someone from his depleted and food starved regime please inform him that I too have a Nuclear Button, but it is a much bigger more powerful one than his, and my Button works!”
The Marine Corps has started fielding a new plate carrier vest that features a more streamlined cut and offers a 25% weight savings over the vests Marines currently wear.
The new Plate Carrier Generation III will go first to infantry and other combat-arms Marines and then to supporting units in a push to reach full operational capability by fiscal 2023, according to a recent Marine Corps Systems Command announcement.
The Corps selected Vertical Protective Apparel LLC in September 2018 to manufacture up to 225,886 of the lighter and better-fitting Plate Carrier Generation III in an effort to increase the performance of Marines on the battlefield.
“When you lighten the load, Marines can get to their destinations faster, and they’re going to have more endurance, which increases their lethality,” Lt. Col. Andrew Konicki, the program manager for Infantry Combat Equipment at Marine Corps Systems Command, said in a statement. “The PC Gen. III is important because it is nearly 25-percent lighter than the legacy technology.”
Military.com reached out to Systems Command for the average weight of the PC Gen. III compared to the current plate carrier but did not receive an immediate response.
The Marine Corps conducted a study in 2016 using the prototype of the new plate carrier, which involved Marines wearing it while running through obstacle courses and taking a 15-kilometer hike, according to the release. The study results showed that Marines completed the courses faster and appeared better conditioned when wearing the newer plate carrier design, it states.
Program officials worked with industry to remove excess bulk from the legacy plate carrier to reduce weight and give Marines more freedom of movement for handling weapons.
“The PC Gen. III improves the Marines’ ability to shoot and move by eliminating excess bulk from the design, and cutting out the shoulders for a better rifle stock weld,” Lt. Col. Bryan Leahy, who leads the Individual Armor Team at PM ICE, said in the release.
The PC Gen. III is better-fitting than the current vest. It fits closer to the body, increasing protection and decreasing the risk of injury because of improper fit, according to the release.
The Marine Corps also added more sizes, so nearly 15,000 more male and female Marines will be able to get a proper fit when wearing the system, it adds.
“I think there’s a misconception that all females are small, and that’s not always true,” said Konicki. “We conducted a study that found the smallest Marine is actually male.”
Every day, countless men and women who served in the armed forces return home from war with wounds that are invisible — most never reach out to seek help.
As new mental health treatments are developed, many don’t want to be placed on a cocktail of medication they can’t pronounce and put them in a fog. That’s where an organization called Mutual Rescue can help.
David Whitman and Carol Novello created a national animal-welfare initiative that aims to connect loving and homeless pets with people who are in need of specialized care.
“Even before he was my cat, before he even knew me that well, Scout saved my life,” said Josh Marino, an Iraq war vet. “He put me on a different path. He gave me the confidence to try to come back from all the adversity that I was feeling.”

A Philippine Airlines Boeing 777 plane had to make an emergency landing after it caught fire shortly after takeoff on Nov. 21, 2019.
Video footage of the incident posted to Twitter showed the plane’s right engine spewing black smoke before appearing to catch fire and shooting out flames.
Flight 113 took off from Los Angeles International Airport at 11:45 a.m. local time but had to make an emergency landing because of a “technical problem” in one of its engines shortly after takeoff, according to a statement from Philippine Airlines.
The airline said all 342 passengers and 18 crew members were safe and were able to disembark using regular airstairs.
“We greatly appreciate the calmness and patience of our PR113 passengers, who cooperated well with our cabin crew during the flight and the emergency landing,” Philippine Airlines said in the statement.
Andrew Ames watched the incident and told Reuters: “It almost looked like backfire flames from a motorcycle or car.”
It is not immediately clear what the exact cause of the technical problem in the engine was.
GE Aviation, the company that makes the engine for the Boeing 777, said it was aware of the incident and was “working with the airline to determine the cause of the event and to promptly return the aircraft to service,” according to Reuters.
Boeing is under scrutiny following the deadly crashes involving its 737 Max aircraft, which killed a combined 346 people, led to questions over the plane’s design, and left the aircraft grounded across the world.
Training standards, regulatory oversight, and pilot experience have also been called into question following the scandal.

President Donald Trump’s flurry of tweets to kick off the new year lasted into the late evening Jan. 2, as he launched another fiery message to North Korean leader Kim Jong Un.
“North Korean Leader Kim Jong Un just stated that the ‘Nuclear Button is on his desk at all times,'” Trump tweeted. “Will someone from his depleted and food starved regime please inform him that I, too, have a Nuclear Button, but it is a much bigger more powerful one than his, and my Button works!”
Kim, in a televised speech on Jan. 1, had spoken of a “nuclear button” that was “always on my desk.”
“This is reality, not a threat,” Kim said. “This year we should focus on mass producing nuclear warheads and ballistic missiles for operational deployment. These weapons will be used only if our security is threatened.”
North Korean Leader Kim Jong Un just stated that the “Nuclear Button is on his desk at all times.” Will someone from his depleted and food starved regime please inform him that I too have a Nuclear Button, but it is a much bigger more powerful one than his, and my Button works!
Though Trump touted a “nuclear button,” a physical button that a US president can push to initiate a nuclear strike does not appear to exist. Instead, a briefcase — referred to as the “football” — carries authentication codes and is carried by a military aide wherever the president goes.
Trump’s threat comes amid another warning from the U.S. ambassador to the United Nations, Nikki Haley, who on Jan. 2 seemed dismissive of proposed high-level talks between South Korea and North Korea.
“We won’t take any of the talks seriously if they don’t do something to ban all nuclear weapons in North Korea,” Haley said during a press conference. “We consider this to be a very reckless regime, we don’t think we need a Band-Aid, and we don’t think we need to smile and take a picture.”
Though current U.S. officials have panned negotiations between North Korea and South Korea, former U.S. officials — including former Director of National Intelligence James Clapper — and many analysts appear to have accepted North Korea’s nuclear ambitions and have approved the call for negotiations.
“I can well envision a scenario where they would juxtapose a missile test and as well agree to talk with the South Koreans, which I think would be a good thing,” Clapper said. “It would do a lot, I think, to relax some of the tensions. I think negotiation is the only way ahead here — to me, there is no other realistic option.”
A US defense bill would bar delivery of the F-35 Joint Strike Fighter to Turkey until the US government provides an assessment of the relations between Washington and Ankara — a move that comes over the objections of Defense Secretary Jim Mattis and underscores growing tensions between Turkey and its NATO partners.
The conflict with Turkey — which fields NATO’s second-largest army and hosts important NATO infrastructure — stems largely from its decision to buy the Russia-made S-400 air-defense system, one of the most advanced systems of its kind on the market.
NATO officials have cautioned Ankara about the purchase, saying the missile system would not be compatible with other NATO weapons and warning of “necessary consequences” for acquiring it. Using the F-35 and the S-400 together could compromise the F-35 and expose sensitive information.
Turkey plans to buy roughly 100 F-35s and has already received two of them. The country’s defense industry has also taken an active role in the jet’s development, with at least 10 Turkish companies building parts for it.
S-400 surface-to-air missile systems.
But the measure agreed upon by the House and Senate Armed Services Committees on July 23, 2018, would bar Ankara from getting any more F-35s until the Pentagon delivers a report on how the measure would affect US-Turkey relations, what impact Turkey’s purchase of the S-400 will have, and what the effects of Turkey’s removal from the F-35 program would be for the US industrial base, according to Bloomberg.
The bill also includes a statement calling on Turkey to release “wrongfully detained” US citizens Andrew Brunson and Serkan Golge.
The Defense Department has 90 days to submit its assessment. The defense bill, which allots 7 billion for fiscal year 2019, still needs final approval; the House is expected to vote this week and the Senate could do so in early August 2018.
Mattis also urged Congress not to block Turkey from acquiring the F-35, telling legislators in a July 2018 letter that doing so would cause an international “supply chain disruption” that could cause delays and additional costs.
“If the Turkish supply chain was disrupted today, it would result in an aircraft production break, delaying delivery of 50-75 F-35s, and would take approximately 18-24 months to re-source parts and recover,” Mattis said.
In the letter, Mattis said the Trump administration was pressuring Turkey over the S-400 as well as the detention of US citizens on charges the US has called exaggerated. He also acknowledged lawmakers’ concerns with Turkey’s “authoritarian drift and its impact on human rights and the rule of law.”
Mattis has cautioned lawmakers against sanctions on other partners, like India or Vietnam, for buying Russian weapons, including the S-400, arguing that they need to time to shift away from that weaponry. The compromise reached by US lawmakers would let Trump waive sanctions on countries doing business with Russia if the country in question is working to distance itself from Russian defense and intelligence firms.

The dispute over the S-400 purchase comes amid broader friction between Turkey and its partners in NATO — tensions that Turkey has helped stoke by boasting of the S-400’s abilities to target NATO aircraft.
Erdogan has said he pursued the Russian-made system because NATO countries declined to extend deployments of their Patriot air-defense systems and would not sell Turkey a comparable system. Erdogan has also expressed frustration with the EU over its response to a coup attempt against him in 2016 and accused the bloc of “messing us about” on issues like visas and Syrian migrants.
The US’s support for Kurdish fighters in Syria has also created tension with Turkey, which recently said it would not abide by Washington’s request that other countries stop buying oil from Iran.
While tensions with NATO may push Ankara to consider new relationships, it remains closely entwined with the trans-Atlantic defense alliance and its defense industry is reliant on Western firms. Turkey could expand dealings with other non-US partners in Europe, but it’s not clear those countries or the US would assent to such a shift.
Turkey’s warming relations with Russia and Erdogan’s crackdown have already alienated some in the US.
“Turkey may be an ally, but it is not a partner,” Richard Haass, the president of the Council on Foreign Relations and former director of policy planning for the State Department, said in September 2017.

A little over a month after the Helge Ingstad sank after colliding with a tanker in a Norwegian fjord, the Norwegian military has released footage from the submerged frigate.
The warship was rammed by a Malta-flagged tanker in the early morning hours of Nov. 8, 2018, in the port of Sture, north of Bergen, which is Norway’s second-largest city.
The frigate displaces 5,290 tons, and the tanker displaces over 62,500 tons when empty. But when the tanker is fully loaded, as it was at the time of the collision, that jumps to about 113,000 tons, more than an aircraft carrier. The collision tore a large hole in the starboard side of the frigate’s hull, which caused other compartments to flood.
Footage released by the Norwegian military, which you can see below, shows the damage sustained by the frigate.
A Norwegian rescue official said at the time of the collision that the frigate was “taking in more water than they can pump out. There is no control over the leak and the stern is heavily in the sea.”
According to a preliminary report released at the end of November 2018, control of the frigate’s rudder and propulsion systems was lost, which caused the ship to drift toward the shore, where it ran aground about 10 minutes after the collision.

Running aground prevented it from sinking in the fjord, but later, a wire used to stabilize the sunken vessel snapped, allowing it to sink farther. Only the frigate’s top masts remain above the surface.
In December 2018, Norwegian explosive-ordnance-disposal divers returned to the ship to remove the missile launchers from its foredeck.
Below, you can see footage of them detaching the launchers and floating them to the surface.
“All diving assignments we undertake require detailed planning and thorough preparation. We must be able to solve the assignments we are given, while providing as low a risk as possible,” diving unit leader Bengt Berdal said, according to The Maritime Executive.
“Our biggest concern [during this mission] is any increased movement of the vessel.”
With the missiles off the ship, all its weapons have been removed. Recovery crews are preparing to raise the ship, putting chains under the hull to lift it on a semisubmersible barge that will take it to Haakonsvern naval base.
The frigate will not be raised until after Christmas, according to The Maritime Executive.

The oil tanker was not seriously damaged in the incident and didn’t leak any of its cargo. Only eight of the 137 crew aboard the Helge Ingstad were injured, but the multimillion-dollar ship was one of Norway’s five capital Nansen-class frigates and was one of Norway’s most advanced warships. (It also leaked diesel and helicopter fuel, but that was contained and recovered.)
The preliminary report found that the warnings to the frigate, which was headed into the port, went unheeded until too late, allowing the outbound tanker to run into it.
According to the report, the frigate’s automatic identification system was turned off, hindering its recognition by other ships in the area, and there was confusion on its bridge because of a change in watch — both of which contributed to the accident.
The preliminary report also raised questions about other ships in the class and the Spanish shipbuilder that constructed it.
The review board “found safety critical issues relating to the vessel’s watertight compartments. This must be assumed to also apply to the other four Nansen-class frigates,” the report said.
“It cannot be excluded that the same applies to vessels of a similar design delivered by Navantia, or that the design concept continues to be used for similar vessel models.”

Okay, by now, you’ve probably heard that Russian President (seemingly for life) Vladimir Putin recently unveiled some new nuclear weapons. He made some big claims about them, but let’s be honest, it’s really just a lot of hype since these systems are still in development.
Putin claims that the systems cannot be intercepted by American missile-defense systems being deployed to protect NATO. The freshly revealed nuclear systems include an underwater drone capable of attacking American ships or harbors, a nuclear-powered cruise missile, and a hypersonic weapon.
Putin claimed that the new Russian systems were developed in response to American efforts to develop a missile defense system, but it seems as though at least one of these weapons may not be ready for prime time. Reports claim that the nuclear-powered cruise missile has crashed on several test flights in the Arctic. Russia’s long-range underwater drone also remains in the research and development phase.
Lasers travel at the speed of light, roughly 186,000 miles per second. By comparison, Russia’s hypersonic weapon, purportedly capable of traveling Mach 20, would reach a speed of 15,225 miles per hour. With the United States turning to lasers, there’s little chance Russian weapons will outpace American defenses.
In short, the United States has already made huge strides in developing an effective defense against two of Russia’s allegedly “invincible” weapons.
A soldier with the 101st Airborne Division (Air Assault) died Tuesday from injuries he sustained during a live-fire training exercise at the Joint Readiness Training Center at Fort Polk, Louisiana.
The Army is not releasing many details until the soldier’s family has been notified, unit spokesman Master Sgt. Kevin Doheny said in a May 11 press release.
Soldiers and emergency services personnel responded to the incident and transported the soldier to Bayne-Jones Army Community Hospital on Fort Polk, where he was later pronounced dead, according to the release.
It wasn’t clear if the soldier was shot during the live-fire exercise.
Seaman James “Derek” Lovelace was pulled out of the pool Friday after showing signs he was having difficulty while treading in a camouflage uniform and a dive mask, Naval Special Warfare Center spokesman Lt. Trevor Davids said.
Lovelace lost consciousness after being pulled out of the pool and was taken to a civilian hospital, where he was pronounced dead, Davids said. He was in his first week of SEAL training after joining the Navy about six months ago, Davids said.
GNC filed for Chapter 11 bankruptcy protection on Tuesday night, announcing that it expects to close between 800 and 1,200 stores while on the hunt for a buyer for its business. The vitamins and supplements retailer had about 7,300 stores as of the end of March.
In a letter to shoppers, GNC said the COVID-19 pandemic “created a situation where we were unable to accomplish our refinancing and the abrupt change in the operating environment had a dramatic negative impact on our business.”
GNC identified 248 stores that would close imminently as part of the restructuring process. Stores are closing in 42 states, as well as in Puerto Rico and Canada.

Marines from Marine Corps Systems Command and 7th Engineer Support Battalion along with engineers from the U.S. Army Corps of Engineers Construction Engineering Research Laboratory conducted the first known 3D concrete printing operation with a three-inch print nozzle at the CERL headquarters in early August 2019 in Champaign, Illinois.
The CERL, MCSC and 7th ESB team tested a new continuous mixer and three-inch pump for this print operation after successfully printing multiple structures, including a barracks and a bridge using, a two-inch pump and hose.
“This is really the first time we’ve ever printed something large with this system,” said Megan Kreiger, project lead for the Automated Construction of Expeditionary Structures — or ACES — team at CERL. “It is experimental right now and we are trying to push the technology forward. This is the first time in the world anyone has really tried using these larger bead systems with these larger pumps.”
Increasing from a two-inch to a three-inch nozzle allows Marines to print larger structures faster and with less waste, according to Kreiger. The teams have envisioned printing with up to a four-inch nozzle in the future.

While this was the first known printing of concrete with a three-inch hose and nozzle, the exercise was also significant because it incorporated a continuous mixer similar to the one currently fielded to Marines.
“The new mixer we are testing is a commercial model of a mixer that is already within the Marine Corps repertoire in the Airfield Damage Repair Kit,” said Capt. Matthew Audette, project officer for the Advanced Manufacturing Operations Cell at MCSC. “That means we don’t have to field a new piece of gear in addition to the printer to make this work.”
This time the team printed a bunker that was designed by the Drafting and Survey combat engineers from 7th ESB based on practical field experience.
“The Marines from 7th ESB are the ones who designed what we are printing today,” said Audette. “They came up with the plans themselves, [Computer Aided Designed] the model, sliced it and then fed it through the printer.”

The 7th ESB Marines plan to build a conventional bunker similar to this 3D-printed version and compare them in blast or demolitions testing on a range.
The combat engineers envisioned a system like this being deployed to a forward operating base, and being operational within a few days of arrival. The system would quickly print small structures that can be transported to entry control points and operating posts in an efficient and timely manner using fewer Marines and less material.
According to ACES team data, 3D printing concrete structures reduces cost by 40 percent, construction time by 50 percent and the use of concrete materials by 44 percent. Additionally, it more than doubles the strength of walls, improves thermal energy performance by 10 times, reduces manpower by 50 percent and reduces the overall need for hard labor.
“With vertical construction, we are still in the realm of what we were doing 100 years ago,” said Audette. “Working with the Army Corps of Engineers to develop this technology we are reducing the man-hours involved, the labor involved and the materials involved.”
