Even in peaceful times, stockpiled warheads can pose a danger if they’re accidentally set off or fall into the wrong hands. Plus, there’s always a chance conflict could escalate, which is why many experts support dismantling nuclear warheads around the world.
But most arms-control treaties don’t require warheads to be inspected, since the process could reveal military secrets. And even if inspections were required, nuclear experts worry that nations could try to fool inspectors by offering imitation warheads.
To eliminate the risk that countries would lie about this, two MIT researchers have come up with a novel way to verify that a warhead is authentic — all without revealing how the weapon was built.
The scientists describe the new technology in a paper published in the journal Nature Communications. Their method uses neutron beams: streams of neutrons that can plunge deep into a warhead and reveal its internal structure and composition, down to the atomic level.
The technology, if implemented, could encourage countries like Russia and US to allow their warheads to be inspected and verified as real before they get dismantled.
During the Cold War era, the US and Russia built up their arsenals of nuclear warheads. By 1967, the US had acquired the most warheads in its history — around 30,000. The Soviet Union reached its peak warhead supply in 1986, when it had around 45,000.
When the Cold War ended in 1991, the nations agreed to dismantle some of these weapons, but they didn’t allow each other to inspect the actual warheads. Instead, they showed proof that the devices that carried these warheads, such as missiles and aircrafts, had been torn apart — which meant that the warheads couldn’t be deployed.
The US, for instance, cut off the wings of B-52 bombers and splayed them out in a “boneyard” in the Arizona desert. Russian officials could then verify via satellite that the planes were out of commission.

Today, the US and Russia each have around 4,000 warheads left in their military stockpiles, in addition to around 2,000 warheads each that are “retired,” or ready to be dismantled. The Federation of American Scientists estimates that Russia is dismantling up to 300 retired warheads per year, but confirming that number isn’t easy.
That’s where the technology from the MIT researchers comes in.
The tool captures a warhead’s unique shadow, not classified details
The MIT researchers’ tool can detect isotopes like plutonium, which are found in the core of a warhead, since those atoms release specific wavelengths of light. These measurements then pass through a filter that scrambles and encrypts them. This allows a warhead’s unique structure to get probed without any resulting 3D image of its exact geometry. (It’s kind of like looking at a shadow of the warhead rather than the object itself.)

The researchers estimate that the scan can be completed in less than a hour.
The test’s encryption process is more secure than encrypting information on a computer, which can be hacked.
If nations are confident that their military secrets are safe, the researchers said, they could be more inclined to allow their warheads to be inspected. Of course, the method would need to be more thoroughly vetted before it could be implemented, they added.
But eventually, they said, it could help to “reduce the large stockpiles of the nuclear weapons that constitute one of the biggest dangers to the world.”

John Browning got it right when he designed the .50 caliber machine gun in 1918. Nicknamed “Ma Deuce,” the .50 cal is considered the mother of all machine guns. Nearly nine decades after its introduction, the weapon is still getting positive reviews.
“It’s just a sexy weapon,” said SPC Sterling Jones in the video clip below from Sebastian Junger’s 2010 war documentary, “Restrepo.” “It’s the ultimate machine gun. That thing fires at an incredible rate, it’s not hard to maintain, it’s pretty simple, and it’s pretty reliable. Guys run and wrestle for the .50 cause it’s just the most fun to shoot.”
Add its effectiveness and reliability, and it doesn’t look like this weapon is going out of style anytime soon. The Ma Deuce is just too good.
Since relocating from Yuma, Arizona, to Iwakuni, Japan, in January, the Marine Corps’ first squadron of F-35B Joint Strike Fighters has been hard at work ironing out the basics of operations in the Pacific, from streamlining supply chains to practicing “hot reloads” and rapid ground refueling from a KC-130.
In fall 2017, the unit — Marine Fighter Attack Squadron 121 — will deploy aboard the amphibious assault ship Wasp with the 31st Marine Expeditionary Unit.
And the squadron is well aware that a sea deployment in the tense Pacific could well entail responding to a regional crisis or a combat contingency, Lt. Col. Richard Rusnok, the squadron’s commanding officer, told Military.com in an interview this month.
“When I was a young guy in [AV-8B] Harrier land in 2003, several MEUs … were in a normal deployment and something happened, and they ended up in a bigger picture,” Rusnok said, referring to MEU-based combat units dispatched to Iraq to assist with ground operations during the invasion. “That’s something that could really happen. Given the small numbers of F-35s that are out there, I think [combatant commanders] are going to look at that and say, ‘I’ve got six airplanes out on the MEU. I could do something with them.’ ”
VFMA-121 has hit milestones not just for the Marine Corps, but for the entire Defense Department since late 2012, when it became the first squadron to activate with the 5th-generation fighter.
The unit’s reception in the Iwakuni community has been warm, Rusnok said. Iwakuni Mayor Yoshihiko Fukuda attended the March change-of-command ceremony for the unit, and an aviation day at the air station drew a crowd of 210,000, with locals surrounding a displayed F-35B “six or seven deep,” he said.
While the squadron has not begun shipboard training, set to happen later this summer, it’s already preparing for the upcoming MEU deployment in practical ways, standing up and proving out logistics capabilities and supply chains for the F-35 in the Pacific.
Working Out Supply Chains
Rusnok noted that, in the space of months, the Joint Strike Fighter program went from being based almost solely in the continental United States to having aircraft in Israel, Italy, and Japan, among other locations.
“That’s such an incredibly complicated, such an exponential growth in geography that it’s almost hard to fathom, if you rewind back several years, to see we’re this far along,” he said. “What we’ve done, I think, at Iwakuni is to break down some of these barriers and find out how that airplane is supportable in the Asia-Pacific region.”
The squadron has worked with the Pentagon’s F-35 Joint Program Office and aircraft maker Lockheed Martin to find faster ways to ship gear and replacement parts, and to send broken parts back to the United States to repair. With a global supply chain and a relatively small number of active aircraft, sometimes a plane in need of a part at Luke Air Force Base in Arizona must get it shipped from Iwakuni, and vice versa.
“Iwakuni is distinctly different from CONUS-based units, not only because of the tyranny of distance in the Pacific region, but we also have a wide variety of places we could potentially go,” Rusnok said. “Expeditionary maintenance logistics are incredibly important to what we do.”
The squadron got to hone its fighting skills earlier this month at Northern Edge, a 12-day training exercise at Joint Base Elmendorf-Richardson, Alaska.
The exercise included the Air Force’s 5th-generation F-22 Raptor, as well as numerous fourth-generation fighters, including the F/A-18 Super Hornet, the F-15 Eagle and the F-16 Fighting Falcon.
In the exercise, the largest VFMA-121 has participated in since moving forward to Iwakuni, the F-35s were able to drill on joint operations in the Western Pacific, focusing on aerial interdiction, strike warfare, air-to-air, and offensive counter-air missions.
Rusnok said the F-35’s kill ratio from the exercise was not immediately available, though one of the missions he flew racked up eight kills and zero losses, he said, a fairly indicative statistic.
But he doesn’t particularly like to talk about those stats.
“Everyone likes to focus on that air-to-air piece. It robs that statistic out of a bigger scenario,” he said. “You never hear about the surface-to-air kills we got, the enemy systems degraded. There’s a bigger picture.”
The exercise, Rusnok said, also tested the F-35’s ability to create a “God’s-eye view” of the battlespace, with its ability to network and transmit information. Northern Edge showed, he said, that the capability remained strong, even in a dense radio frequency environment that hindered transmissions.
“Where other air systems have problems, we’re able to cut through that so easily,” he said. “Our ability to resist that kind of attack on the electromagnetic spectrum is huge.”
Testing Maintenance Software
The squadron also brought with it a deployable version of its Autonomic Logistics Information System, a software designed to revolutionize F-35 maintenance that has been hampered by production and upgrade delays. A 2016 Government Accountability Office report questioned whether ALIS was truly able to deploy in practice, citing a lack of redundancy in the system.
“Every time we deploy this airplane, we make a decision whether to deploy ALIS or leave it home,” Rusnok said.
In this case, he said, the squadron worked with the Air Force to make necessary modifications to host the ALIS deployable operating unit, hardware that travels with the squadron when connectivity is an issue. Overall, Rusnok said, the system worked well during the exercise, and preparing to use it offered insights on its future use.
“Let’s say we’re going to an Air Force base in Country X — we know those facilities are now compatible with ALIS,” he said. “Maybe we can take advantage of this and put it in our playbook as something we can do, optimize to really cut down on that logistics footprint.”
Now back in Japan, the squadron has already begun early preparations for its upcoming deployment, conducting rapid ground refueling tests using the KC-130 Hercules and practicing “hot reloads” in which the aircraft receives new ordnance while the pilot remains in the cockpit.
The unit’s pre-deployment preparations will likely provide insights for units that come after. The next F-35B deployment, aboard the amphibious assault ship Essex, will come months after VFMA-121 deploys to the Pacific and is expected to take the Corps’ second F-35 squadron, VFMA-211, to the Middle East.
“Come the fall, we’re going to have all the pieces in place so we can effectively deploy the squadron,” Rusnok said.
Thousands of heroes have emerged since the U.S. Marine Corps was founded on November 10, 1775. Here are 11 among them who became Leatherneck legends:
1. Lt. Gen. Lewis B. “Chesty” Puller
Lewis “Chesty” Puller joined the Marines during World War I, but that war ended before he was deployed. He saw combat in Haiti and Nicaragua before the outbreak of World War II.
In the Pacific theater of World War II, Puller led an American advance that succeeded against a huge Japanese force at Guadalcanal. During the Korean War Puller and his Marines conducted a fighting withdrawal from the Chosin Reservoir that crippled seven Chinese divisions in the process. He remains one of America’s most decorated warriors with 5 Navy Crosses and numerous other high-level awards.
2. Sgt. Maj. Daniel J. Daly
Sgt. Maj. Daniel J. Daly was called “the fightinest Marine I ever knew” by Maj. Gen. Smedley Butler. He is possibly most famous for leading outnumbered and outgunned Marines in a counterattack at the Battle of Belleau Wood with the rallying cry, “Come on, you sons of b-tches, do you want to live forever?”
He also received two Medals of Honor. The first was for single-handedly holding a wall in China as Chinese snipers and other soldiers tried to pick him off. The second was awarded for his role in resisting an ambush by Caco rebels in Haiti and then leading a dawn counterattack against them.
3. Maj. Gen. Smedley Butler
Like Daly, Maj. Gen. Smedley Butler is one of the few people who have received two Medals of Honor. His first was for leading during the assault and occupation of Vera Cruz, Mexico in 1914. Eighteen months later he led a group of Marines and sailors against Caco rebels holed up in an old French fort. For his bravery during the hand-to-hand combat that followed, he was awarded his second Medal of Honor.
John Basilone first served in the U.S. Army in the Philippines but switched to the Marine Corps in time for World War II. He served with distinction in the Pacific Theater and received a Medal of Honor for his actions at Guadalcanal and a posthumous Navy Cross for actions at Iwo Jima.
At Guadalcanal he emplaced two machine gun teams under fire and then manned a third gun himself, killing 38 enemy soldiers before charging through enemy lines to resupply trapped Marines. He later destroyed a Japanese blockhouse on his own and then guided a tank through a minefield and artillery and mortar barrages at Iwo Jima. While escorting the tank, he was struck by shrapnel and killed.
Master Gunnery Sgt. Leland Diamond was possibly the world’s saltiest and most gung-ho Marine recruit when he joined at the age of 27 in 1917. He quickly became known for being loud, not caring about rank or uniform regulations, and always being ready to fight.
Foss was awarded the Medal of Honor for his World War II exploits. After that war, he helped organize the American Football League and the South Dakota Air National Guard. He deployed to Korea with the Air National Guard and rose to the rank of brigadier general before retiring. He died in 2003.
9. Cpl. Joseph Vittori
Cpl. Joseph Vittori made his mark on Hill 749 in Korea on Sep. 16, 1951. Vittori and his fellow Marines were securing a hill they had just taken from Chinese forces when a counterattack forced a 100-yard gap that could’ve doomed the U.S. forces. Vittori and others rushed into the opening with automatic rifles and machine guns.
Sgt. Charles “Chuck” Mawhinney may not have the name recognition of Carlos Hathcock, but he has 10 more confirmed kills with 103. Mawhinney’s work in the Vietnam War was almost forgotten until a book, “Dear Mom: A Sniper’s Vietnam” revealed that he had the most confirmed kills in Marine Corps history.
One of the scout sniper’s greatest engagements came when an enemy platoon was attempting to cross a river at night on Valentine’s Day to attack an American base. Mawhinney was on his own with an M-14 and a starlight scope. He waited until the platoon was in the middle of crossing the river, then dropped 16 NVA soldiers with 16 head shots.
11. Sgt. Maj. Gilbert “Hashmark” Johnson
Gilbert Johnson served in both the Army and Navy for a total of 15 years before joining the Corps. When he began Marine Corps basic training, he was nicknamed “Hashmark” because he had more service stripes than many of his instructors.
The name Giora Epstein might not ring a bell at first, but it is one you should know.
After all, he is the top-scoring jet ace of all time.
According to the Israeli Defense Forces web site, Epstein has 17 confirmed kills. The Jewish Virtual Library breaks them down as follows: two were MiG-17 “Fresco” fighters; one was a Mi-8 “Hip” helicopter; three were Su-7 “Fitter” ground attack planes; two were Su-20 “Fitter” attack planes; and nine were MiG-21 “Fishbed” fighters.
The site notes that Epstein’s first five kills were in the Mirage III, the rest in the Nesher (a “pirated” Mirage 5).
Eight of those kills came over two days during the Yom Kippur War.
It is an impressive total. To make it even more impressive, Epstein, who flew until 1997, was skunked in the Bekaa Valley Turkey Shoot of June, 1982.
Perhaps his most impressive aerial feat was when he ended up on the wrong end of a 1-v-11 dogfight against Egyptian MiG-21s. According to the “Desert Aces” episode of the series “Dogfights,” Epstein’s flight of four Nesher fighters was jumped by over a dozen MiG-21s, just after Epstein shot down one of two Fishbeds that had drawn the assignment of being the decoy pair.
Epstein’s wingman shot down one MiG, but his engine was damaged by the exhaust from his Shafrir-2 air-to-air missile. Another of Epstein’s flight ran low on fuel, and headed back to base, while another of the Nesher pilots chased a MiG out of the main dogfight.
That left Epstein alone against 11 Fishbeds. It was not a fair fight… for the MiGs.
Epstein shot down the lead MiG of the decoy pair, then managed to outduel the other five pairs of MiG-21s shooting two of the Fishbeds down. When he returned to base, having scored four kills that day, ground crew had to lift him from the plane. Four days later, Epstein bagged three more Fishbeds, giving him 11 kills in less than a week.
Typically, losing a limb is a career ender for troops. After all, they’ve already given enough and surely they won’t be able to withstand the rigors of combat without all four limbs.
Except, yes, they can. These 6 warriors lost limbs in battle, laughed in the face of death, and came back to fight another day:
1. Gen. Frederick M. Franks, the architect of Desert Storm
Gen. Frederick M. Franks was the commander behind the “Left Hook” of the American invasion of Iraq in Desert Storm. Franks’ armored formations surged north into Iraq and toppled over a dozen Republican Guard divisions. And he led the whole operation with one leg.
He and Gen. Eric Shinseki, who survived a partial amputation of his foot in Vietnam, used to show their prosthetics to new amputees in Walter Reed. The tours were designed to remind the younger soldiers that they could still achieve great things after an amputation.
2. Alexei Maresyev, a Hero of the Soviet Union
Alexei Maresyev had just graduated flight training when the Nazis invaded the Soviet Union and he was called on to fly against the technologically advanced Luftwaffe. In Jun. 1942, the young pilot was shot down over German-occupied territory and had to crawl for 18 days back to Russian lines. The frostbite and the injuries from the wreck resulted in both his legs being amputated.
But Maresyev fought his way back to active duty, partially because he was already respected for four aerial kills before he was shot down. In 1943 he again took to the air against the Nazis and shot down another seven enemy aircraft before the war ended, earning him the title “Hero of the Soviet Union.”
3. Douglas Bader, legendary pilot in the Battle of Britain
Like Maresyev, Bader was a respected pilot who lost his legs in a crash. Bader’s injuries resulted from an air show crash in 1931. The Royal Air Force retired him but said he might be able to return if war broke out. He spent the next eight years perfecting flight with prosthetics.
4. Capt. Jean Danjou, the Legionnaire who fought “France’s Alamo”
Jean Danjou graduated the French military school at Saint-Cyr and joined the army as an officer. After fighting Algerian nationalists in the 1840s, he volunteered to serve in the French Foreign Legion. At the Battle of Sevastopol, Danjou lost his left hand.
In 1863, Danjou led a 66-man element which came under attack by approximately 2,000 Mexican soldiers. He led a fighting withdrawal to a nearby estate at Camerone and rallied his men for an 11-hour battle. The unit was nearly wiped out but inflicted hundreds of Mexican casualties. Danjou died in the fighting. His prosthetic hand is now paraded in France every year at commemorations of the battle. The battle is sometimes described as “France’s Alamo.”
He repeatedly attacked Union Maj. Gen. William Sherman’s troops in an attempt to stop the march to the sea and relieve the pressure on Atlanta in 1864. After fighting there, Hood led troops in the defense of Tennessee in the Battles of Franklin and Nashville. With the Union Army marching south, he attempted to rally troops in Texas in 1865 but was eventually captured.
Don’t worry, destroying North Korea will wait long enough for you to take a bathroom and memes break. Here are 13 of the funniest military memes floating around, here just in time to help you relieve yourself before the Super Bowl of war:
Recent North Korean missile launches, including four into the Sea of Japan earlier this month, have prompted a major deployment of U.S. forces, including B-52 Stratofortress bombers, also known as BUFFs (for Big Ugly Fat F*ckers), and F-35B Lightning II fighters to the Korean peninsula.
According to a report by The Sun, the deployments come as part of the Foal Eagle exercises, which are held by American and South Korean forces. Other assets being deployed in support of the exercises include the nuclear-powered aircraft carrier USS Carl Vinson (CVN 70) and its strike group, as well as B-1B Lancer heavy bombers.
The B-52s can carry a wide variety of ordnance.
Some of the things that they can deliver a lot of to the North Koreas, if Kim Jong Un continues on his present course, include dumb bombs (usually the Mk 82 500-pound bomb or the M117 750-pound bomb, but Mk 84 2,000 pound bombs are an option as well), AGM-86 cruise missiles in both conventional or nuclear versions, AGM-84 Harpoon anti-ship missiles, CBU-87 cluster bombs, CBU-97 cluster bombs, GBU-31 Joint Direct Attack Munitions (2,000 pound GPS guided bombs), the AGM-142 HAVE NAP missile, the AGM-158 JASSM, and the AGM-154 Joint Stand-Off Weapon.
The F-35s that will participate are Marine Corps F-35B variants that are based in Japan. The F-35Bs are fifth-generation multi-role strike fighters, capable to engaging targets in the air or on the ground. The planes carry AIM-120 AMRAAMs, AIM-9 Sidewinders, JDAMs, JSOWs, and cluster bombs.

The planned exercises will involve 315,000 troops, most of them South Korean. North Korea has routinely claimed that the Foal Eagle exercises are rehearsals for an invasion. Earlier this month, a battery of Terminal High-Altitude Area Defense missiles were deployed to South Korea, a decision criticized by China, which vowed to make South Korea “feel the pain” for allowing the deployment.
Someone needs to tell Kim, “You’re making Chaos angry. You will not like it when Chaos gets angry.”
A Special Air Service sniper who spotted a group of Islamic State fighters leaving a suspected bomb-making facility in Iraq fired three shots that detonated two suicide vests and killed all five fighters, according to reports in British media.
The SAS sniper was operating 800 meters away from the factory when he noticed the group wearing unseasonably warm and bulky clothing. The 10-year veteran of the SAS hit the first man in the chest and detonated his vest, killing three fighters. As the two survivors attempted to escape back into the factory, the sniper shot one in the head and the other in the vest, which detonated the second vest.
“This was a classic SAS mission,” a British Army source told the Express. “About three weeks ago the intelligence guys got information that a bomb factory had been set up in a nearby village. With just three well-aimed shots, that single team has probably saved the lives of hundreds of innocent people. The unit was sent in to see if they could identify the house and the bombers.”
The decision to attack with a sniper was made due to concerns about collateral damage.
“There were too many civilian homes nearby and children were often around so an airstrike was out of the question,” the unidentified British Army source said. “Instead, the SAS commander in Iraq decided to use a sniper team and the operation was a complete success.”
From the formation of the Air Force in 1947 to today, the flying branch’s sexiest assets have always been its fighters. These soaring agents of death intentionally fly into fights in one of the planet’s most unforgiving environments.
Here are 8 of the machines that defined Air Force fighter history:
1. P-51 Mustang
The P-51, renamed in 1948 to the F-51 when the Air Force changed its plane designation system, was one of the fighters that the U.S. Air Force inherited when it morphed from the Army Air Force. The beloved Mustang variant served with distinction in the Korean War, but mostly as a close-air support asset, not as a fighter.
One of the main reasons that later F-4 variants couldn’t redeem themselves in American service is that the F-15 Eagle overshadowed the F-4 from day one. The Eagles boast powerful engines that gave it nearly unprecedented speed as well as “look down, shoot down” radar, powerful missiles, and a 20mm Gatling gun. The F-15 is still in service with the U.S. and feared by adversaries around the world.
7. F-16 Fighting Falcon
With a long combat radius, all-weather, and day and night capabilities, the F-16 is prepared to fly, fight, and win everywhere. While the F-16 is a capable strike aircraft, its greatest value may reside in its capabilities as one of the world’s premier dogfighters.
8. F-22 Raptor
The reason that the F-16 isn’t the world’s premier dogfighter is that the F-22 exists. The Raptor can sneak up on its prey and watch it for minutes without the enemy ever knowing it was there. Or, it can shoot down opposing fighters from outside of its adversaries detection and engagement ranges.
Currently, the plane is serving as a sensor platform in Iraq and Syria where it detects enemy air defenses and guides friendlies around them, but it could eradicate other fighters in the sky on a moment’s notice.
