Today it costs the U.S. Navy about $2.6 billion and just under 2.5 years to build a Virginia-class sub. But a joint endeavor by the Department of Energy and the Department of Defense could greatly reduce those costs going forward.
3D printing has been around for a while – and in 2015, a Royal Air Force Panavia Tornado flew with parts that had been made that way. But this latest effort takes things to a whole new level. It also hit the news when Defense Distributed released plans for 3D-printed firearms.
The mini-submarine in the video appears to be very similar to SEAL Delivery Vehicles. These are used to help SEAL infiltrate in and out. Normally these hulls cost about $800,000 to make over a period of months, but 3D printing can reduce the cost by 90 percent and create the hull in a matter of weeks.
The logistical advantages for 3D printing are also significant – offering the ability to custom-design needed parts. That saves time in getting a plane or vehicle back into the fight, and that time could save lives.
One prototype has been built, and a second is planned. They will be tested by the Navy.
If all goes well, these printed SDVs could be in service by 2019. To see more about this, watch the video below.
Chips, a German shepherd, collie, husky mix, was the most famous and decorated sentry dog in World War II, one of 10,425 dogs that saw service in the Quartermaster Corps’ new “K-9 Corps.” Prior to the K-9 Corps, dogs such as Admiral Wags on the carrier Lexington and World War I canine hero Sergeant Stubby were mascots without any official function.
The K-9 Corps was the culmination of a program begun by the Dogs for Defense, a civilian organization created in January 1942 by a group of notable dog experts and the American Kennel Club. Concerned about the vulnerability of America’s long coastline to infiltration by enemy saboteurs, it offered to provide the Army and Coast Guard with trained sentry dogs. After some initial resistance, the Army authorized an experimental program using 200 dogs. The success of that program caused the Quartermaster General to authorize the acquisition of 125,000 dogs (later reduced). Of the 10,425 dogs that served in the military during the war, most conducted sentry duty along America’s coastline and at military installations. But roughly 1,000 dogs were trained as scout dogs. Chips was one of those dogs.
Chips’ owner was Edward J. Wren of Pleasantville, New York, who enlisted Chips in the Army in August 1942. After training at the War Dog Training Center in Front Royal, Va., he was assigned to Pvt. Rowell. Chips participated in Operation Torch, and was one of three dogs assigned guard duty for the Roosevelt/Churchill Casablanca Conference.
In the predawn hours of July 10, 1943, the 3rd Infantry Division under the command of Maj. Gen. Lucian Truscott landed on the shore of southern Sicily near Licata in Operation Husky. Among the troops that hit the beach was the 3rd Military Police Platoon, 30th Infantry Regiment, containing Pvt. John R. Rowell of Arkansas and his sentry dog, Chips. As dawn broke, the platoon was working its way inland when a machine gun nest hidden in what appeared to be a nearby peasant hut opened fire. Rowell and the rest of the platoon immediately hit the ground. But Chips broke free from his handler and, snarling, raced into the hut. Pvt. Rowell later said, “Then there was an awful lot of noise and the firing stopped.” The soldiers heard someone inside the hut fire a pistol. Roswell said he then “saw one Italian soldier come out with Chips at his throat. I called him off before he could kill the man. Three others followed, holding their hands above their heads.”
Chips suffered powder burns and a scalp wound from the pistol fired at close range. Medics treated Chips and released him to Rowell later that day. That night, while on guard duty Chips alerted Rowell of an infiltration attempt by ten Italian soldiers. Together they captured all ten.
Within days the story of Chips’ heroics had swept through the division. Chips was awarded the Purple Heart and Silver Star. More was to come. The platoon’s commander, Capt. Edward G. Parr put in a recommendation that Chips receive the Distinguished Service Cross for “courageous action in single-handedly eliminating a dangerous machine gun nest and causing surrender of its crew.”
War Department regulations prohibited the awarding of decorations to animals. But in the case of Chips, Truscott’s attitude was “regulations be damned.” He waived them and on November 19 in Italy he personally awarded Chips the Distinguished Service Cross.
The people back home learned of Chips’ heroism in newspaper stories published on July 14, 1944. While most people were thrilled, acclaim was not universal. The next day the War Department released a statement that it was conducting an investigation, noting the War Department regulations. In addition, William Thomas, the national commander of the Military Order of the Purple Heart, angrily wrote letters to the president, secretary of war, and adjutant general of the U.S. Army protesting that the Purple Heart was a decoration for humans, not animals. Then Congress got into the act. After a debate lasting three months, it decided no more decorations were to be awarded to non-humans adding “appropriate citations may be published in unit general orders.” This meant that at least they would receive honorable discharges.
Though they took away his medals, that didn’t make Chips any less a hero. Among those who honored Chips was Supreme Commander Gen. Dwight Eisenhower. But, when Eisenhower leaned down to pet him, Chips, only knowing that Eisenhower was a stranger and possibly stressed from the attention he had been receiving, nipped the general’s hand.
Chips remained with the 3rd Infantry Division throughout the war. Shortly before he was honorably discharged, the men in his platoon unofficially awarded him a Theater Ribbon with arrowhead for an assault landing and eight battle stars. He returned home to the Wren family in December 1945.
Chips died seven months after coming home from complications of his war injuries at the age of 6. He is buried in the Hartsdale Pet Cemetery in Westchester County, United States of America.
The RCS, a predecessor to the Coast Guard, responded by forming a unit of volunteers who traveled 1,600 miles from Dec. 1897 to Mar. 1898, buying reindeer along the way and herding them to Alaska where the sailors were trapped. They arrived with 382 reindeer just in time for most of the survivors. Three people died of starvation, but the rest were rescued during the spring thaw.
2. Army PSYOPS troops pretended they were vampires
American psychological operations soldiers were sent to the Philippines in 1950 to help destroy a Communist rebellion in the country. When the commander learned that the local fighters were superstitious and believed in a shapeshifting vampire known as the “asuang,” he came up with a Scooby Doo-esque plan.
First, he had friendly locals spread a rumor that an asuang was living in the hills. Then, the Americans and their allies set up an ambush in the hills, waited for the last man in a patrol to pass them, and abducted him. They poked two holes in his neck, drained him of his blood, and put his body back on the trail. The rebels bought the ruse and fled the area, allowing government forces to reclaim it.
3. Four Royal Marines rode Apaches into a Taliban fort
Long story short, a British attack on the Taliban base of Jugroom Fort went bad quickly, and British forces quickly withdrew. But, they accidentally left wounded Royal Marine Lance Cpl. Mathew Ford behind. With the Taliban in the fort already on high alert, a daring plan was needed to recover him.
4. The Air Force used actual bears to test ejection seats
The Air Force struggled in the late 50s and early 60s with a simple but challenging problem. Crew who had to eject from supersonic planes were subjected to extreme and sometimes lethal strain. So the Air Force began testing experimental ejection devices — on bears.
The pod was proven safe and nearly all of the test animals returned to the ground safely. Unfortunately, the Air Force needed to check for potentially hidden injuries and ordered autopsies on all animal subjects.
5. Union soldiers stole a train and wreaked havoc across Georgia and Tennessee
What’s the best way to cut off your enemy’s lines of communication? Apparently, in Apr. 1862 Georgia, the answer was to steal on train and go on a GTA: V-type crime spree with it. The operation was led by a civilian but was conducted with the help of 18 Union soldiers.
The men were eventually caught. Eight of them were executed and the rest lived out the war as POWs.
6. American troops used a payphone to call for air support in Grenada
During the invasion of Grenada in 1983, the American communication network was so bad that almost no one on the island could talk to any fighters from another branch. This led to the legend that U.S. troops called for fire support using a credit card and a payphone.
Vice President Dick Cheney heard the story while he was a Congressman and was told that an Army officer could see naval artillery out at sea but couldn’t get them on the radio. So he pulled out his credit card and used a payphone to call the Pentagon who relayed his request.
The Navy SEALs have their own version of the story that said the frogmen were holed up in the governor’s mansion and used a credit card to call the Pentagon and get help from an Air Force AC-130.
7. American and Nazi troops teamed up to defeat an SS attack during World War II
In the closing days of World War II, a group of American and German troops teamed up and fought side-by-side against a murderous SS battalion. The Americans had accepted the surrender of the Germans just before both sides saw the slightly drunk and very fanatical group of SS soldiers climbing the hill towards them.
Adam West was born, and drafted into the Army, as William West. In the military, he was in charge of standing up TV stations at San Luis Obispo, California, and Fort Monmouth, New Jersey. But if it seems odd that the star of a farcical show like the 1966 version of “Batman” got his start in the Army, it was actually the perfect way to prepare for such a ridiculous show.
Here are six reasons why:
1. Renaming everything to some arbitrary standard like “bat cuffs,” “bat time,” and “bat channel,” makes sense for anyone who has had to relearn names for Velcro, Duck Tape, and zipper
Those are ridiculous ways of referring to Velcro, Duck Tape, and zippers, which are all brand names that the Army can’t use in official doctrine. So young Billy West would have gotten used to using the Army names. It was probably easy to start calling everything “bat” later in life.
2. Dealing with a group of ne’er-do-wells like the “Batman” villains is old hat for anyone who has dealt with an Army squad
Penguin, Riddler, Catwoman, Archer, and other crazy villains were always hatching insane schemes in the Batman TV show. But, once again, the Army would’ve prepared the future Bruce Wayne for this.
Soldiers decide to get high with spice and bath salts? Yup, sounds about right. Troops smuggling liquor overseas by pouring it into Listerine bottles and mixing in food coloring? Seen it. Enlisted hijinks are basically Silver Age Batman ridiculous, just without the fancy gadgets and costumes.
3. Having to mentor a grown adult while treating them like a child is how all specialists deal with new privates
One of the more awkward truths about the Batman is that Robin, the Boy Wonder, was actually a 21-year-old man when the show began. The grown adult Adam West had to act like mentoring another grown man while treating him like a child wasn’t sort of weird.
But again, the Army is perfect preparation for this. After all, most specialists have only been in the military for a few years and they can be assigned responsibility of a private first class who has been in the Army a couple of years. So, 24-year-old supervising 20-year-olds.
4. Spending all of your time with an attractive lady without giving in is easy for any NCO who had to ignore their co-ed lieutenant’s good looks
One of Batman’s greatest villains was Catwoman, who definitely had a thing going on with Batman. But Batman refused to give in to it (though he almost kissed her once, and a later incarnation of Batman ran off to Europe with her).
But any specialist or sergeant who has pulled overnight duty with an even moderately attractive officer knows what it’s like to weigh the consequences of “fraternization” over and over. Chances are, young and attractive Billy West had to say no to a few female sergeants and officers, or at least find the right place to give in without getting caught.
5. Only in the military and “Batman” can the little stuff be crucial during an emergency
This is a small one, but most organizations will let little things go during an emergency. But Batman doesn’t accept any of that crap from Robin. Proper grammar is important, and Batman corrects Robin even as Catwoman tries to get away on a rocket.
You know, just like a sergeant major yelling about gloves during a firefight or reflective belts during literally anything.
6. Working within made-up rules is easy for anyone who has dealt with UCMJ and Rules of Engagement
Batman runs into some pretty stupid bureaucratic problems during the show, like that time the Riddler sues Batman (while using riddles to explain his scheme, because of course he did) for false imprisonment and assault.
When you think about Grumman fighters, the Wildcat, the Panther, and the Tomcat all spring to mind. And for good reason — these planes are all classics. But there is one Grumman fighter that didn’t quite get a chance to shine in World War II, but it did see some action in Southeast Asia.
Grumman F8F Bearcats line up on the Essex-class aircraft carrier USS Valley Forge (CV 45)
During World War II, the Navy was deploying the F6F Hellcat and the F4U Corsair was operated by the Marine Corps. The Hellcat was a very tame plane, but the Corsair — known as the “Ensign Eliminator” and foisted on the Marines — simply had higher performance. The Navy wanted the best of both planes. They wanted the F8F Bearcat.
French F8F Bearcats prepare to take off to carry out a napalm strike in Southeast Asia.
At the heart of the Bearcat was the Pratt and Whitney R-2800. This was the powerplant used by both the Corsair and Hellcat, but the Bearcat was much lighter, which gave it extreme performance. The Bearcat also packed a significant punch — to the tune of four M2 .50-caliber machine guns. If that wasn’t enough, the Bearcat was also able to haul five-inch rockets or a 1,000-pound bomb.
The Bearcat’s primary mission was to intercept enemy planes. The plane had a “bubble” canopy (pretty much a standard feature on today’s fighters) to improve the situational awareness of pilots. The Bearcat had a top speed of 421 miles per hour and a maximum range of 1,105 miles. It stuck around long enough to see some upgrades, but was quickly replaced by the onset of fighter jets, like the F9F Panther.
While taking enemy contact, a Chinese mortar struck a Marine bunker near where replacement Marine Cpl. Salvatore Naimo was engaging opposing forces. From this position, he heard the screams of his wounded comrades coming from inside the newly-damaged area.
Naimo, who joined the Marines to avoid being drafted into the Army, dashed over to aid his brothers, exposing himself to enemy fire.
As mortars continued to destroy the surrounding area, Naimo spotted two severely wounded Marines and scooped up one of them up, protecting him with his own body. Soon after, Naimo dropped off the first injured Marine at the aid station and headed right back for the second man as waves of incoming enemy fire blanketed their position.
After returning to the aid station with the second wounded Marine, Naimo informed the corpsmen that he was going to head back to the bunker and continue to fight.
Upon his arrival at the unmanned bunker, he was lucky to discover the Marines before him had stockpiled it with machine guns, ammo, and extra grenades. As the next wave of Chinese attacks throttled, Naimo fired the arsenal of weapons into the enemy — who closed within 15 yards of his position.
Hours later, Marine Lt. Walter Sharpe came across Naimo’s bunker, where he found 36 dead soldiers from the 65th Army Group of Mongolian laid out. Sharpe decided to recommend Naimo for the Navy Cross but sadly was killed in action two days later. He never filed the proper paperwork to get Naimo his Navy Cross.
More than six decades after his heroic efforts, then-Lt. Bruce F. Meyers (who was injured in that same battle) filed the necessary paperwork to award Cpl. Salvatore Naimo the well-deserved Navy Cross.
Asked on Thursday by Rep. Tim Ryan of the House Appropriations Committee to explain why the US doesn’t just go to war to stop North Korea from developing the capability to hit the US, Secretary of Defense James Mattis painted a grim scenario.
“I would suggest that we will win,” Mattis said. “It will be a war more serious in terms of human suffering than anything we’ve seen since 1953.
“It will involve the massive shelling of an ally’s capital, which is one of the most densely packed cities on earth,” Mattis said of Seoul, South Korea, which boasts a metro-area population of 25 million.

“It would be a war that fundamentally we don’t want,” Mattis said, but “we would win at great cost.”
Mattis explained that because the threat from North Korea loomed so large and a military confrontation would destroy so much, he, President Donald Trump, and Secretary of State Rex Tillerson had all made a peaceful solution a top priority.
Mattis said the topic of North Korea dominated Trump’s meeting in April with President Xi Jinping of China, North Korea’s only ally, and that the US intended to make China understand that “North Korea today is a strategic burden, not a strategic asset.”
China argues it has limited influence on Pyongyang, but as one expert explained, Beijing could at any moment cripple North Korea through trade means, forcing it to come to the negotiating table.
Mattis made clear that the US was nearing the end of its rope in dealing with North Korea, saying: “We’re exhausting all possible diplomatic efforts in this regard.”
North Korea recently taunted Trump by saying it was capable of hitting New York with a nuclear missile, but Mattis said a war today would hurt our Asian allies.
“It would be a serious, a catastrophic war, especially for innocent people in some of our allied countries, to include Japan most likely,” Mattis said.
More than 120 years later, the cultural meaning of the song has sure changed. No longer associated with martial might, the song is now more easily teamed up with clowns, lions, and everything else in a modern three-ring circus.
What happened was his work was rearranged for a smaller band by Canadian Louis-Philippe Laurendeau in 1910, who called his version “Thunder and Blazes.”
The music website Sound And The Foley points out that this was the same time when circuses like PT Barnum’s and the Ringling Brothers’ were becoming a strong cultural phenomenon in the United States.
Though no one knows just how and when the song first became inextricably linked with the circus or even which circus used it first, the fact is that the two are now culturally linked.
Both Laurendeau and Fucik died in 1916, never knowing their work become synonymous with the circus…instead of being battle anthems.
Back in World War II, patrol torpedo, or PT, boats were the scourge of the Japanese Navy. These vessels were so small, they weren’t even measured in tons, but rather by feet. The Elco PT boat was 80 feet long, and the Higgins PT boat was 78.
Many were discarded after World War II, but the Soviet Union, China, and some NATO allies brought the concept back, this time equipping them with anti-ship missiles, like the MM38/MM40 Exocet, the Penguin, and the SS-N-2 Styx.
In the 1980s, the United States got into the game with the Pegasus-class hydrofoil.
The Pegasus was all of 255 tons, according to the Federation of American Scientists. It carried some serious firepower, though: A single 76mm gun, like those used on the Oliver Hazard Perry-class frigates (and later, the Coast Guard’s Hamilton-class high-endurance cutters) forward and eight RGM-84 Harpoon anti-ship missiles. That’s a lot more than what you see on today’s Littoral Combat Ships.
The Navy bought six of these vessels and based them at Key West, Florida. There, they helped keep an eye on Fidel Castro’s dictatorship and pitched in to fight the War on Drugs. With a top speed in excess of 45 knots, these boats could chase down just about anything on the waves, and their firepower gave them a good chance of defeating any vessel the Cuban Navy could throw at them. That said, these vessels were expensive to operate and suffered from short range.
With the end of the Cold War, the PHMs were among the many assets retired. All six were retired on July 30, 1993. Four of the vessels were scrapped immediately. A fifth, USS Gemini (PHM 6), became a yacht for a brief time before she went to the scrapyard. The lone surviving vessel in this class is the former USS Aries (PHM 5), which is slated to become part of a hydrofoil museum.
Just before midnight on Feb. 27, 1943, a team of 10 Norwegian commandos crouched in the snow on a mountain plateau and stared at a seemingly unassailable target. It was a power plant and factory being used by the Nazis to create heavy water, a key component for Germany’s plans of developing nuclear reactors and a nuclear bomb.
The Norsk Hydro plant was surrounded by a ravine 656 feet deep with only one heavily-guarded bridge crossing it. Just past the ravine were two fences and the whole area was expected to be mined. On the factory grounds, German soldiers lived in barracks and walked patrols at all hours.
As a bonus, the whole area was covered by a thick layer of snow and the men were facing two causes of exhaustion. Six of the men were worn out from five days of marching through snow storms after they were dropped 18 miles from their planned drop zone. The other four men were survivors of an earlier, failed mission against the plant. They had survived for months in the mountains on only lichen and a single reindeer.
Still, to keep the Germans from developing the atom bomb, they attacked the plant on Feb. 28. The radio operator stayed on the plateau while the other nine climbed down the ravine, crossed an icy river, and climbed the far side soaking wet.
Once at the fence, a covering party of four men kept watch as the five members of the demolition party breached the first and then second fence lines with bolt cutters. The men — wearing British Army uniforms and carrying Tommy guns and chloroform-soaked rags — arrived at the target building.
Unfortunately, a door that was supposed to be left open by an inside man was closed. The team would later learn that the man had been too sick to go to work that day. Plan B was finding a narrow cable shaft and shimmying through it with bags of explosives. The covering party provided security while the demolition team split into two pairs, each searching for the entrance.
Lt. Joachim Ronneberg and Sgt. Frederik Kayser were the first to find the shaft. When they couldn’t immediately find the other pair in the darkness, they proceeded down the shaft alone and pushed their explosives ahead of them.

They dropped into the basement of the factory and rushed the night watchman. Kayser covered the man with his gun and Ronneberg placed the explosives on the cylinders that held the heavy water produced in the plant.
Suddenly, a window shattered inward. Kayser swung his weapon to cover the opening but was pleased to find it was only the other demolition pair, Lt. Kasper Idland and Sgt. Birger Stromsheim. They had been unable to find the shaft and were unaware that the others were inside. To ensure the mission succeeded, they had risked the noise of the breaking window to get at the cylinders.
Idland pulled watch outside while Ronneberg and Stromsheim rushed to finish placing the explosives. Worried that German guards may have heard the noise, they cut the two-minute fuses down to thirty seconds.
Just before they lit the fuses, the saboteurs were interrupted by the night watchman. He asked for his glasses, saying that they would be very challenging to replace due to wartime rationing. The commandos searched the desk, found the spectacles, and handed them to the man. As Ronneberg again went to light the fuses, footsteps approached from the hall.
Luckily, it wasn’t a guard. Another Norwegian civilian walked in but then nearly fell out of the room when he saw the commandos in their British Army fatigues.
Kayser covered the two civilians with his weapon and Ronneberg finally lit the 30-second fuses. Kayser released the men after 10 seconds and the commandos rushed out behind them. Soon after they cleared the cellar door, the explosives detonated.
Jens Poulsson, a saboteur on the mission, later said, “It sounded like two or three cars crashing in Piccadilly Circus,” according to a PBS article.
The cylinders were successfully destroyed, emptying months worth of heavy water production onto the floors and down drains where it would be irrecoverable.
The teams tried to escape the factory but a German guard approached them while investigating the noise. He was moving slowly in the direction of a Norwegian’s hiding spot, his flashlight missing one of the escaping men by only a few inches. Luckily, a heavy wind covered the noise of the Norwegian’s breathing and dispersed the clouds of his breath. The guard turned back to his hut without catching sight of anyone.
The team left the plant and began a treacherous, 250-mile escape on skis into Sweden, slipping through Nazi search parties the entire way.
Germany did repair the facility within a few months and resumed heavy water production. After increased attacks from Allied bombers, the Germans attempted to move this new heavy water back to Germany but a team of Norwegian saboteurs successfully sunk the ferry it was transported in. One man, Knut Haukelid, participated in both the factory and the ferry sabotage missions.
