The Navy Can Now 3D-Print Submarines On The Fly For SEALs
It usually takes the Navy around five months to build even the smallest submarines to ferry Navy SEALs into and out of combat zones — but thanks to new technology, the Navy's most elite warfighters could slap together a submersible hull in just a few weeks.
That’s the promise behind the Optionally Manned Technology Demonstrator (OMTD), the U.S. military’s first 3D-printed submarine hull, unveiled by the Navy on July 24. Fabricated by the high-tech Big Area Additive Manufacturing 3D printing machine at the Oak Ridge National Laboratory, the 30-foot submersible hull was inspired by the SEAL Delivery Vehicles used by the branch and U.S. Special Operations Command to deploy Navy special warriors and their gear into particularly dangerous areas.
But while a traditional SEAL submarines cost up to $800,000 apiece and take three to five months to manufacture, six carbon-fiber composite sections of the OTMD took less than a month and only $60,000 to assemble, according to the Department of Energy — a shift that the Navy claims could massively reduce production costs.
The Department of Defense and global defense industry have put a premium on 3D printing (or “additive manufacturing,” if you want to be technical) for years, ranging from Army Armament Research, Development and Engineering Center’s fabricated “RAMBO” grenade launcher to portable printing units designed to help Marines repair essential gear faster downrange.
But the OTMD, apparently now the Navy’s largest 3D printed asset, represents a massive leap forward in terms of “on-demand” manufacturing. Rather than slap together expensive and time-consuming materiel requests during the long federal budgeting process, military personnel could simply fabricate vehicles and supplies on demand to adapt to changing operations. With U.S. special operations forces leading the charge in the Global War on Terror, assets like the OTMD could greatly increase their operational flexibility — and effectiveness.
According to the Navy, fleet-ready prototypes of the OTMD could hit the water as soon as 2019 — which, depending on who you ask, probably isn’t soon enough.
A Minnesota Army National Guard UH-60 Black Hawk helicopter with three Guardsmen aboard crashed south of St. Cloud on Thursday, said National Guard spokeswoman Army Master Sgt. Blair Heusdens.
At this time, the National Guard is not releasing any information about the status of the three people aboard the helicopter, Heusdens told Task & Purpose on Thursday.
The Pentagon's latest attempt to twist itself in knots to deny that it is considering sending up to 14,000 troops to the Middle East has a big caveat.
Pentagon spokeswoman Alyssa Farah said there are no plans to send that many troops to the region "at this time."
Farah's statement does not rule out the possibility that the Defense Department could initially announce a smaller deployment to the region and subsequently announce that more troops are headed downrange.
The Navy could deploy a second carrier to the Middle East if Trump orders an Iran surge, top admiral says
The Navy could send a second aircraft carrier to the Middle East if President Donald Trump orders a surge of forces to the region, Chief of Naval Operations Adm. Mike Gilday said on Thursday.
Gordon Lubold and Nancy Youssef of the Wall Street Journal first reported the United States is considering sending up to 14,000 troops to the Middle East to deter Iran from attacking U.S. forces and regional allies. The surge forces could include several ships.
I didn't think a movie about World War I would, or even could, remind me of Afghanistan.
Somehow 1917 did, and that's probably the highest praise I can give Sam Mendes' newest war drama: It took a century-old conflict and made it relatable.
An internal investigation spurred by a nude photo scandal shows just how deep sexism runs in the Marine Corps
"I will still have to work harder to get the perception away from peers and seniors that women can't do the job."
Some years ago, a 20-year-old female Marine, a military police officer, was working at a guard shack screening service members and civilians before they entered the base. As a lance corporal, she was new to the job and the duty station, her first in the Marine Corps.
At some point during her shift, a male sergeant on duty drove up. Get in the car, he said, the platoon sergeant needs to see you. She opened the door and got in, believing she was headed to see the enlisted supervisor of her platoon.
Instead, the sergeant drove her to a dark, wooded area on base. It was deserted, no other Marines were around. "Hey, I want a blowjob," the sergeant told her.
"What am I supposed, what do you do as a lance corporal?" she would later recall. "I'm 20 years old ... I'm new at this. You're the only leadership I've ever known, and this is what happens."
She looked at him, then got out of the car and walked away. The sergeant drove up next to her and tried to play it off as a prank. "I'm just fucking with you," he said. "It's not a big deal."
It was one story among hundreds of others shared by Marines for a study initiated in July 2017 by the Marine Corps Center for Advanced Operational Culture Learning (CAOCL). Finalized in March 2018, the center's report was quietly published to its website in September 2019 with little fanfare.
The culture of the Marine Corps is ripe for analysis. A 2015 Rand Corporation study found that women felt far more isolated among men in the Corps, while the Pentagon's Office of People Analytics noted in 2018 that female Marines rated hostility toward them as "significantly higher" than their male counterparts.
But the center's report, Marines' Perspectives on Various Aspects of Marine Corps Organizational Culture, offers a proverbial wakeup call to leaders, particularly when paired alongside previous studies, since it was commissioned by the Marine Corps itself in the wake of a nude photo sharing scandal that rocked the service in 2017.
The scandal, researchers found, was merely a symptom of a much larger problem.
