You’ve seen the colorful patches that adorn the shoulders of the uniforms worn by high-profile officers. Whether they’re on Colin Powell, H. R. McMaster, or some other Army or Marine general, these patches stand out. They represent the units these officers served with — but who designed them?
Believe it or not, nobody in the military did. Well, no active-duty member of the military, to be precise. Instead, the designing of unit patches has been the work of 32 civilians out of Fort Belvoir, near Alexandria, Virginia, at The Institute of Heraldry, U.S. Army. This agency, often called TIOH, has been around since 1960, but military units have been using distinctive patches, flags, and symbols since 1775.
The Institute of Heraldry, U.S. Army has its own coat of arms.
After World War I saw an explosion in unit patches, the Army got serious about creating an official program to sort it all out. The Quartermaster General began handling the design of unit patches in 1924. Then came World War II. Not only did every division get a patch, it seemed every regiment, fighter squadron, and bomber squadron wanted one, too (remember, the Air Force didn’t break away from the Army until 1947). In 1957, Congress tacked on more responsibility, putting the Army in charge of designing the seals and flags for every federal agency.
Finally, in 1960, TIOH was formed, and placed under the Adjutant General’s Office. Several decades and reorganizations later, the institute now operates under the Office of the Administrative Assistant to the Secretary of the Army.
The shoulder patch for the 101st Airborne Division — The Screaming Eagles — reflects that division’s name and heritage.
Through it all, as new units have formed and old ones have faded away, TIOH has helped keep the history alive through their intricate, symbolic design work.
China launched its first domestically-built Type 055 guided-missile stealth destroyer in July 2017, and since then, has added three more Type 055s to its fleet, with the last two launched in July 2018.
In regards to propulsion, Type 055s have four QC-280 gas turbines, each providing about 23-28 megawatts of energy. This large amount of energy may one day power railguns or other future weapons systems.
The Zumwalt, on the flip side, has two Rolls-Royce MT30 gas turbines, providing the ship with 78 megawatts of energy, including 58 megawatts in reserve. This reserve power may also power railguns or high-energy lasers in the future.

But the Zumwalt only has 80 VLS cells, each of which have a diameter of about 2.3 feet.
The Zumwalt VLS cells can fire Tomahawk, Evolved Sea Sparrow, and other guided missiles.
It’s also equipped with two 155 mm Advanced Gun Systems on the bow, and two Mark 46 close-in guns which fire 30 mm rounds. Rounds for the AGS are so expensive, about id=”listicle-2612880833″ million apiece, that the Navy doesn’t have any and has no plans to buy them, rendering the deck guns effectively out of service.

Ultimately though, the two destroyers will have different mission sets.
Type 055 destroyers will focus more on air defense, anti-submarine missions and protecting carriers, which is why they have more VLS cells and a longer range than the Zumwalt. These mission sets, along with its large size, are why the US has even classified the Type 055 as a cruiser.
The XQ-58A Valkyrie demonstrator, a low-cost unmanned air vehicle, successfully completed all test objectives during a 71-minute flight, June 11, 2019, at Yuma Proving Grounds, Arizona.
The test marked the second successful flight for the aircraft this year. The inaugural 72-minute flight was recorded in March 2019.
The Air Force Research Laboratory developed the low-cost unmanned air vehicle together with Kratos Defense & Security Solutions, Inc. The joint effort falls within AFRL’s Low Cost Attritable Aircraft Technology portfolio, which has the goal to break the escalating cost trajectory of tactically relevant aircraft.
“The XQ-58A is the first Low Cost Attritable Aircraft Technology flight demonstrator with (unmanned aircraft systems) technology to change the way we fly and fight, and build and buy,” said Doug Szczublewski, program manager.

There are a total of five planned test flights for the XQ-58A, with objectives that include evaluating system functionality, aerodynamic performance, and launch and recovery systems.
The Air Force Research Laboratory is the primary scientific research and development center for the Air Force. AFRL plays an integral role in leading the discovery, development and integration of affordable warfighting technologies for our air, space and cyberspace force. With a workforce of more than 11,000 across nine technology areas and 40 other operations across the globe, AFRL provides a diverse portfolio of science and technology ranging from fundamental to advanced research and technology development.
Because, as hemlines grew shorter, the need to cover scandalous lady skin with something — anything — grew larger, but we won’t get into that now. Suffice it to say that American women were wearing silk stockings. Unfortunately, they didn’t stretch, they were delicate and ripped easily, and they often required an extra garment, like a garter belt, to hold them up.
Enter Harvard-trained scientist, Wallace H. Carothers, hired by E.I. DuPont de Nemours and Company to conduct research on synthetic materials and polyblends. In 1939, Carothers invented Fiber 6-6, or what would become known as Nylon.
DuPont astutely recognized the economic value of Nylon as a silk replacement and concentrated on manufacturing nylon stockings. Within three hours of their experimental debut, 4,000 pairs of nylon stockings sold out. Later that year, they were displayed at the New York World’s Fair. The next year, 4 million pairs of brown nylons sold out within two days, making a total sales figure of million.
In 1941, the company sold million worth of nylon yarn — that’s nearly 0 million today. In just two years, DuPont earned 30% of the women’s hosiery market.
But all of that was about to change.
Used stockings were repurposed into war materials.
(Franklin D. Roosevelt Library)
Because stockings weren’t the only thing made of silk. Military parachutes and rope were also made from the Japanese import. After the Pearl Harbor attack, the United States went to war against Japan and, suddenly, the production of nylon was diverted for military use.
It was used to make glider tow ropes, aircraft fuel tanks, flak jackets, shoelaces, mosquito netting, hammocks, and, yes, parachutes.
Eventually, even the flag planted on the moon by Neil Armstrong would be made of nylon!
Buzz Aldrin salutes Old Glory ON THE MOON.

This is because nylon is a thermoplastic polymer that is strong, tough, and durable. It is more resistant to sunlight and weathering than organic fabrics are and, because it is synthetic, it’s resistant to molds, insects, and fungi. It’s also waterproof and quick to dry.
By utilizing it during World War II, we were better-equipped than our enemies and more able to weather difficult conditions.
Back home, women missed their stockings. At the time, they were made with a bold seam up the back. After experiencing nylon stockings, women didn’t want to go back to silk, so they did the next best thing: they shaved their legs, carefully applied a “liquid silk stocking” (otherwise known as paint), and lined the backs of their legs with a trompe l’oeil seam.
A bold, new revolution was happening: leg hair removal to replicate the appearance of stockings. After the war, the trend continued to spread, inflamed by the beauty industry’s marketing.
Beauty standards: poisoning women’s bodies since the invention of paint…
After 1942, the only stockings available were those sold before the war or bought on the black market. One entrepreneurial thief made 0,000 off stockings produced from a diverted nylon shipment.
Which is very messed up — everyone in America was coming together to support the war effort, including women!
After the war, nylon stockings made a resurgence. On one occasion, 40,000 people lined up for a mile to compete for 13,000 pairs of stockings. They remained standard in the industry, and still to this day “nylons” are synonymous with “pantyhose” or tights. In many fields, they are required for women — including the military. If a female wears a skirt, she must wear stockings or hose underneath.
The main reason most people cite for their energy drink consumption is to get enough caffeine to get through the day. Been there, done that. I’m pretty sure there are more soul-sucking jobs in existence than fulfilling ones–we can’t all write for We Are The Mighty and spend the rest of our time surfing… the waves are getting crowded and that’s my job, you can’t have it.
Let’s look at the math for exactly how much caffeine is in the average energy drink versus a cup of coffee.
Does he look cool or just tired? Hand tattoo optional…
The average cup of coffee contains up to 170 mg of caffeine. In some cases, like a 20 oz venti from Starbucks, it could contain up to 415 mg of caffeine.
The caffeine content in energy drinks is anywhere between 47 to 207 mg.
With the recommended intake of caffeine per day maxing at 400 mg/day, it seems like you could easily get your caffeine fix from either drink. So what is the real case for spending over .00 on a can of what looks like nuclear reactor run-off?
Many energy drink companies associate themselves with athletics and extremely fit people. The insinuation is that if you drink this product, you’ll become a freak athlete, you’ll look great with your shirt off, and you’ll be jumping from balloons way up in the stratosphere in no time flat.
Well, my friends, let’s see if the research on energy drinks supports their subliminal messaging.
Before I poop all over your favorite energy drink, I will happily admit that they have been shown to increase alertness and performance if consumed immediately before a test or training session.
This makes sense, since the most popular pre-workout ingredient is caffeine, and these things are loaded with caffeine. But is that caffeine enough to carry someone through months and years of training to reach their true fitness goal?
Scientists have shown that energy drinks increase jump height, muscular endurance in the bench press, and performance in tennis and volleyball.
Real subtle…almost accurate, very bombastic.

The bad and the toothless
However, a recent meta-analysis on energy drinks has shown that people who consume energy drinks have:
Increased blood pressure
Increased heart rate
Increased risk of obesity
Increased risk of type 2 diabetes
Increased dental decay
Increased kidney issues
Increased sleep dissatisfaction
Increased stress, anxiety, and depressive symptoms
AND low academic achievement
Before you call bullshit, let me rein in these findings for you. Correlation does not equal causation. No one, even the scientists who conduct the cited studies, is saying that energy drinks in and of themselves cause all of these issues.
What is being said is that people who drink energy drinks also have these other issues. They are describing the profile of someone who tends to drink energy drinks.
This is similar to any other demonized substance or habit. Take for instance red meat eaters, or people who don’t exercise. Many of the same conclusions can be drawn for people that fall into these categories. This is just how science works.
What is true though is that if you are a fan of energy drinks, you probably have other crappy habits that will also contribute to you developing some of the above conditions.
We don’t see the same with coffee drinkers because nearly everyone, except Mormons, drink coffee. We can see similar effects on people who only drink double mocha f*ckaccinos though, because that’s an irresponsible decision.

Long-term studies on energy drink drinkers show only negative effects. Some of these effects are directly related to the actual consumption of energy drinks, like dental decay, but many of them are due to a whole host of combined factors. And that is where the real devil is in these products.
Although they promote active lifestyles, they actually create a vicious cycle that leads to a sedentary lifestyle.
Energy drinks after 3 p.m. disrupt sleep.
Disrupted sleep leads to increased daily fatigue and tiredness.
Tired people are masters at coming up with excuses to not work out.
You can kiss any fitness goal you may have goodbye if you fall into this cycle. Period.
Used properly, energy drinks could be a force multiplier for you in the gym. Used irresponsibly, they will lead you to a slow decline into inactivity, a gross body, and loads of tearful regret about what could have been.
We know our government as one of checks and balances, always ensuring that one branch has oversight over another. But in case of some kind of national emergency, the President of the United States has the ability to essentially turn the democratically-elected government into a sort of constitutional dictatorship, with him (or her) at its center.
This doesn’t mean the chief executive has to enact all the powers at once or that, in an emergency, that they have to enact them at all. These are just the possibilities. In case you read this and think to yourself, “Holy cow, no one is ever going to really do that!” Guess again. Most of these have been done before.
Precedents for the President
There are four aspects to an emergency: the sudden onset and how long it will last, how dangerous or destructive it is, who it may be dangerous to, and who is best suited to respond. The President has to declare a state of emergency and indicate which powers he’s activating.
“We should ask the President,” said no businessperson ever.
1. Regulate all commerce and business transactions.
Under the Trading with the Enemy Act of 1917, the President is allowed to regulate all the finances of the United States, including all international transactions.
Pictured: Not yours.
2. Seize all privately-held gold stores.
Under the same 1917 act of Congress, the President has the authority to take all privately-owned gold coin, gold bullion, and gold certificates. The last time this was used was in 1933 to mitigate the effects of the Great Depression. Citizens were allowed to keep only 0 worth of gold.
Citizens were paid its value per ounce and for the cost of transportation as they were required to surrender the gold to a Federal Reserve Bank within three days of the order.
Better make room for a new logo.
3. Take control of all media in the U.S.
Under the Communications Act of 1934, the President can establish the Office of Telecommunications Management, which oversees all media and telecommunications, regardless of advances in technology. President Kennedy did this through Executive Order 10995 in 1962.
Make way for the Trump Train!
4. Basically capture all resources and manpower.
Kennedy also signed executive orders allowing for the seizure of electric power fuels and minerals, roads, highways, ports, sea lanes, waterways, railroads, and the private vehicles on those throughways. Under further orders, he allowed for the Executive Office of the President to conscript citizens as laborers, seize health and education facilities, and airports and aircraft. These are continued in Executive Orders 10997, 10999, 11000, 11001, 11002, 11003, 11004, and 11005.
Just wait til they get bored on their deployment to Wyoming.
5. Deploy the military inside the United States.
While American governors can offer their National Guard resources to the President without being ordered, as they do in the case of U.S. troops monitoring the border with Mexico, the use of Active Duty troops inside the U.S. is forbidden under the Posse Comitatus Act of 1878…
…unless there’s an emergency. The Insurrection Act allows for the President to use troops to put down insurrections or rebellions within the United States. After Hurricane Katrina, however, the Insurrection Act was amended to allow the POTUS to use federal troops to enforce the law — a violation of the Posse Comitatus Act. Every U.S. Governor was against this change.
Like an inauguration but with waaaaaaaaay fewer people.
6. Suspend the government of the United States.
A presidential directive signed by George W. Bush on May 9, 2007, gives the President of the United States the authority to take over all government functions and all private sector activities in the event of a “catastrophic emergency.” The idea is to ensure American democracy survives after such an event occurs and that we will come out the other end with an “enduring constitutional government.” This piece of legislation is called “Directive 51.”
Amazon Prime is pushing their new show, Jack Ryan, based on the Tom Clancy character that has saved Britain’s queen, hunted Russian subs, and interrupted terrorist plots across the world in both novels and movies from the ’80s to today.
The character is a mainstay of the the thriller world — an American James Bond — which is why it’s so great that Amazon cast comedy icon John Krasinski in the role.
Now, Funny or Die has done what we’ve all been thinking — they cut together the Jack Ryan commercial and scenes from The Office, pitting America’s top analyst-turned-spy against the criminal genius of Dwight Schrute, the socially awkward and pretentious beet farmer who’s always hatching some failed scheme to teach his office mates a moral lesson.
Jim (left) feigns working at his desk as Dwight (center) looks at what he believes to be a gift-wrapped desk. Spoiler: The desk is actually gone completely. Jim made a fake frame for the wrapping and the whole thing collapses when Dwight tries to sit down.
Dwight is best known by his self-appointed job title: Assistant to the Regional Manager. Abbreviated, of course, as the Ass. Man.
He labors for years to outmaneuver Jim Halpert, now Jim Ryan, in a series of escalating pranks, from disappearing desks to fake spy taps to false faxes from the future. Apparently, Dwight is not putting up with it any longer.
Check out the hilarious video mashup below and get a look at more sinister Dwight Schrute.
Jack Ryan debuted August 31, but has already been been renewed for a second season. In the first season, Ryan notices irregularities in bank transactions and eventually finds evidence of a growing terrorist threat against the U.S., leading him across the world in a quest to hunt down the leaders and prevent the attack.
The show brings Michael Bay and John Krasinski back together. The men had previously worked together on 13 Hours: The Secret Soldiers of Benghazi, a dramatization of the horrible events at the U.S. embassy in Libya in 2012. 13 Hours was probably the most well-known example of Krasinski’s pivot from comedy to action.
After years of playing Jim Halpert in The Office and performing other comedic roles, Krasinski has been branching out, directing movies and focusing on action roles.
Once you step off base and meet that potentially special someone, here’s a few pointers before you go full steam ahead:
1. Wrap it up
You may have built up pounds and pounds of muscle these last few months in training, but it only takes a microscopic bacterium to bring all that strength crashing down.
Don’t be a fool, wrap your tool. (Image via Giphy)If you do hook up with someone soon after meeting them, don’t expect to be their first (even if that’s what they told you).
As a newbie, you might get stationed overseas in a foreign country where the lifestyles and customs can be very different. Make sure you do a little reconnaissance on the do’s and don’t’s or you might send the wrong message at the dinner table.
We told you so. (Images via Giphy)
3. Background check
We’re not suggesting you conduct a full scale credit and background check on your date, but it couldn’t hurt.
We’re saying to casually ask what mommy and daddy do for a living because many young guys and gals who you’ll meet near the base have parents who served.
You don’t want to hit on someone and find out later you broke the heart of the general’s son or daughter.
Congrats, you’re going to be an E-3 for the rest of your career. (Images via Giphy)
4. Putting ring on it
No offense to all the average looking service members out there, but if you are stationed in a foreign country and you hook up with a “10,” they might be trying to find a way to the states and gain citizenship.
Let’s face it, life would be pretty sweet…until she swears in then takes off. (Images via Giphy)
5. Financial security
Dating and then marrying a service member has some pretty good financial benefits; be careful of who you let into that world.
It happens more than you think. (Images via Giphy)
These days, having the guts to do something just means someone is brave enough to take on what seems to be an overwhelming undertaking. Any herculean task could require guts: quitting a job, suing city hall, or voting third party could all require a gut check by today’s standards. In days past, however, a gut check was only required by the soldiers who were about to fight in combat.
For the record, it still is.
Armies in the days of yore – before the 20th Century – faced very different problems than the ones deployed American troops face today. Where we have been known to wince every time we see a runner missing his reflective belt or wonder why I always get the goddamned vegetarian MRE, the Army of the pre-World War I days was more worried about things like clean drinking water, cholera, and dysentery.
It’s amazing how they can smile even when the stupid chow hall is out of Diet Coke *again*
In days gone by, if someone asked a soldier if they had the guts to fight the coming day or the next day, it wasn’t just an affirmation of macho willpower, it was a real question of a soldier’s ability to maintain his position and discipline in the ranks instead of running off to the latrine every ten minutes to evacuate his bowels.
The asker’s “gut check” was real – and literal – checking to see if his comrade in arms was suffering from diarrhea or a similar illness of the bowels that would keep him from performing at the front lines. Maintaining the integrity of certain infantry formations used to be integral to the survival of the whole unit.
“Jesus, what is that smell, Kenneth?”
At the time of the U.S. Civil War, microbes were only just being accepted as cause for disease. In that war, 620,000 men were killed, but disease actually killed two-thirds of those men. A single illness such as measles could wipe out entire units. Battlefield sanitation was the order of the day, but if Civil War troops chose to ignore an order, that would be the one. Latrines were dug near camps, wells, and rivers as horse and mule entrails and manure permeated their camps.
As a result, dysentery was the single greatest killer of Civil War soldiers. Having the guts to fight only meant you were one of very few troops not suffering from the trots.
Notice the combination there? Aviation, radio engineering, and technical problems? That’s because he was very interested in how radio waves reflected off of objects; how radar actually worked at the most detailed and precise levels. He didn’t know it, but his work would put him at the forefront of a new American industry: stealth engineering.
And certain shapes were unlikely to reflect much energy back to the radar, meaning you could make a large object appear very small if you just gave it the right shape.
Much of Ufimtsev’s work was quietly translated into English where a number of American scientists read it. A 1962 paper translated as Method of Edge Waves in the Physical Theory of Diffraction was of particular interest. Many U.S. scientists simply saw the paper and incorporated it into their own research, or they rebuffed it and went about their day. But there was one team of engineers who saw the paper and saw it as potentially groundbreaking.
Lockheed engineers working in the “Skunk Works” division, the same engineers who made America’s first jet fighter during World War II, saw the chance to create something entirely new and novel. What if they could create an entire plane with the shapes and materials that sent little energy back to a radar?
Such a plane could be large, like the size of a bomber or fighter, but would show up on radar as a little bit of electromagnetic noise. It would be invisible as long as no one knew to look for it, and it would still be challenging to detect even after its existence was disclosed.
(U.S. Air Force Senior Airman Thomas Barley)
Best of all, the growing number of homing missiles that American pilots would face would become essentially useless. Homing missiles needed a strong radar signal to get within range of an enemy target before switching to a seeker built into the missile. This process would almost certainly not work against a stealth aircraft, making the pilots much safer.
There were plenty of possible uses for such a plane, but Lockheed started by building a ground-attack plane, though they further camouflaged the program by labeling it a fighter, the F-117 Nighthawk dubbed the “Stealth Fighter.” The same lessons were later used in the B-2 bomber and are now present—in new forms—the F-22 and F-35. And some of Ufimtsev’s work will undoubtedly be recognizable in the B-21 Raider.
Most people are familiar with the basics: Slap together enough uranium or plutonium and — kaboom! — you have a nuclear blast. But the details of how these complex devices are made, delivered, and controlled can make the difference between keeping the peace and sparking a cataclysm.
It doesn’t help that there’s more than 60 years’ worth of convoluted terminology surrounding the complex policies and politics of nuclear weapons. There are words like isotopes, tritium, and yellowcake; abbreviations such as HEU, LEU, SSBN, and CVID; and the subtle yet striking difference between uranium-235 and uranium-238.
As US Secretary of State Mike Pompeo resumes talks with North Korea over its nuclear weapons program, we’ve defined some of the most important (and misunderstood) words, phrases, and acronyms here.
That effort could take years to pan out, and it’s guaranteed to get very, very complicated.

1. Nuclear weapon
A conventional explosive device rapidly burns up a chemical to cause a blast. A nuclear weapon, meanwhile — such as a bomb or warhead — splits atoms to release thousands of times more energy.
Yet the term “nuclear weapon” can also refer to a vehicle that’s able to deliver a nuclear attack, such as missiles, fighter jets, stealth bombers, and truck-like mobile launchers. (If flying dinosaurs were alive today and trained to drop nuclear bombs, the creatures may be considered nuclear weapons.)
During weapons inspections like the ones between the US and Russia, nuclear warheads are actually concealed with a piece of cloth; it’s the vehicles, missiles, and launch or bombing bays that are the focus. Without them, a warhead can’t get anywhere quickly.
A Hwasong-14 intercontinental ballistic missile, or ICBM, launching from North Korea.
Technically speaking, an ICBM is any missile capable of delivering a warhead from more than 3,415 miles away. The missile silos in the US in which they’re stored are sprinkled around the country, with most stationed in middle America.
Fallout describes the dangerous leftovers of a nuclear weapon: a cloud of dust, dirt, sand, pebbles, and bits of debris that an explosion has irradiated.
Bombs or warheads detonated near the ground vastly increase the amount of fallout by sucking up soil and debris, irradiating it, and spreading it for dozens if not hundreds of miles. Very fine particles can circle the globe and be detected by special airplanes.
Part of CNO cycle diagram, made just to be illustrative for nuclear reactions in general.
Each element on the Periodic Table has a unique chemical identity but can have different weights, or isotopes.
For example, hydrogen is the smallest atom and is usually made of just one positively-charged proton in its nucleus, or core. Its shorthand name, H-1, specifies its atomic weight. If a chargeless neutron gets added, you get the isotope deuterium, or H-2. Add two neutrons and you have the isotope tritium, or H-3.
All three forms of hydrogen have nearly identical chemistry and can, say, bond with oxygen to form water. But their nuclear properties differ significantly: deuterium and tritium can fuel thermonuclear explosions because their extra neutrons can encourage helium atoms (which have two protons) to fuse together far more easily than H-1 alone.
5. Uranium — including U-238, U-235, and U-233
Uranium is a dense element and a key ingredient in nuclear weapons production. It occurs naturally in ores and minerals and has a few important isotopes.
U-238 makes up about 99.27% of natural uranium and is inert. Less than 1% of the uranium in ore is U-235 — the “active ingredient” that can be used for nuclear reactor fuel or bombs.
U-235 is special because it becomes very unstable when it catches a flying neutron. This capture causes it to split (known as fission), release a huge amount of energy, and shoot out more neutrons. Those neutrons can then split other atoms of U-235 in a chain reaction.
Although plutonium (which we’ll describe in a moment) is now the favored bomb-making material, U-235 was used in the Little Boy bomb that the US dropped on Hiroshima in 1945.
U-233 is another isotope that’s weapons-ready, but it’s only made inside special reactors that no longer exist (for now).
6. Plutonium, including Pu-238, Pu-239, and Pu-240
Plutonium is a metallic element that doesn’t occur in nature, and it most often refers to the isotope Pu-239: the go-to material for modern nuclear weapons.
Only nuclear reactors can make Pu-239. They do so by irradiating U-238 with neutrons. The plutonium can then be separated from the uranium, concentrated, and formed into weapons pits — the cores of nuclear weapons.
Pu-239 can more easily trigger a nuclear explosion than uranium, and with less material; as little as about 10 lbs can be enough.
Plutonium-240 is an unwanted and pretty radioactive byproduct of making Pu-239. It can make bombs prematurely explode and fizzle because it’s fairly radioactive. Pu-238 is a byproduct of Cold War weapons production that generates a lot of warmth and powers NASA’s most adventurous robots in the cold, dark depths of space.
7. Yellowcake uranium
Yellowcake is a powder of uranium oxide that’s made by leaching uranium from natural ores and chemically treating it. Despite its name, it’s most often brown or black in color.
The powder is a concentrated form of natural uranium — about 99.72% U-238 and 0.72% U-235. It’s an important commodity because it can be stockpiled and later processed to extract and enrich U-235.
The U-235 and U-238 isotopes are chemically identical and nearly the same weight — so they’re very hard to separate. However, one of the easiest ways to separate uranium is a centrifuge.
The process starts with converting yellowcake into uranium hexafluoride (UF 6), then heating the compound into a gas. The gas then enters a centrifuge: a tall, hollow tube that spins faster than the speed of sound. The rotation pulls heavier U-238 toward the centrifuge’s outer wall while leaving more U-235 near the middle.
Cascades of centrifuges — one linked to another in long chains — further separate and concentrate each isotope. U-235-rich gas moves through an “upstream” line of centrifuges, growing until a desired level of concentration is reached. Meanwhile, U-238 moves “downstream” until it’s mostly depleted of U-235.
9. Highly enriched uranium (HEU) and low-enriched uranium (LEU)
Highly enriched uranium is any amount of uranium with 20% or more U-235 — the kind that can spur a nuclear detonation.
HEU with a concentration of 85% or more U-235 is considered “weapons-grade,” since that is enough to cause a large and efficient nuclear explosion. But it’s rarely used anymore: It most often goes into special reactors that power naval ships and submarines, can make plutonium, or create medically important isotopes (such as molybdenum-99, which can help diagnose certain heart diseases and cancers).
10. Lithium deuteride (sometimes called lithium hydride)
Lithium deuteride is a whitish salt made of one lithium atom and one deuterium atom (hydrogen-2).
It’s a key ingredient in thermonuclear weapons, also called hydrogen bombs — the most powerful type of nuclear arms. (Russia’s Tzar Bomba thermonuclear weapon, detonated in 1961, was about 3,300 times as powerful as the Hiroshima bomb in 1945.)
A thermonuclear weapon is actually two bombs in one. Energy from the first explosion is absorbed by and “ignites” the lithium deuteride, leading to fusion — where two atoms combine — and creating a plasma many times hotter than the sun.
The process also creates a lot of neutrons. These bullet-like particles can then ram into and split a lot of nearby U-238 in the bomb, vastly multiplying the weapon’s destructive energy.

11. Submarine-launched ballistic missile (SLBM)
An SLBM is a nuclear-tipped rocket that shoots out of launch tubes in an underwater attack submarine.
Unlike most land-based missiles, SLBMs are mobile and very difficult to track. Some models can fly nearly 7,500 miles, which is about 30% of Earth’s circumference. That’s plenty of range to strike any inland target from a coast.
12. Ballistic-missile submarines (SSBN or SSB)
Attack submarines that can launch ballistic missiles are known as SSBs or SSBNs. The “SS” stands for “submersible ship,” the “B” for ballistic” (as in ballistic missile), and the “N,” if present, means “nuclear” (as in powered by a nuclear reactor).
These vessels can stay underwater for 90 days and carry more than a dozen nuclear-warhead-tipped SLBMs — each of which can strike targets thousands of miles inland.
13. Complete, verifiable, and irreversible denuclearization (CVID)
CVID is the strategy that was pursued in disarming Libya of its nuclear weapons. The Trump administration pursued it in initial talks with Kim Jong Un and North Korea.
The approach allows inspectors into a country to count weapons, witness their destruction, disable nuclear reactors, prevent the development of missiles, and perform other watchdog work.
Weapons experts think North Korea will reject CVID, mostly because it’d bar the use of nuclear reactors to produce energy and rule out the development of rockets, which can launch satellites and people into space.
Experts also point out that the strategy has a nasty historical precedent: Libyan ruler Muammar Gaddafi followed through on a US-led CVID program but ultimately ended up dead in the streets.
Deterrence is the idea that if countries have nuclear weapons, the threat of an overwhelming retaliation in response to an attack will keep the peace.
In 1995, a few years after the Cold War ended, Reagan-era government officials wrote:
“Deterrence must create fear in the mind of the adversary — fear that he will not achieve his objectives, fear that his losses and pain will far outweigh any potential gains, fear that he will be punished. It should ultimately create the fear of extinction — extinction of either the adversary’s leaders themselves or their national independence, or both. Yet, there must always appear to be a ‘door to salvation’ open to them should they reverse course.”
Some nuclear weapons experts worry that deterrence will only keep the peace for so long. They also think belief in deterrence encourages the development and spread of nuclear weapons— so if and when nuclear conflict does break out, the catastrophe will be much worse.

Early in its combat testing, a test pilot’s damning report leaked to the press and exposed the world’s most expensive weapons system, the F-35, as a bad dogfighter that the F-16 routinely trounced in mock battles.
But new videos leaked from the US Air Force’s F-35 demo or stunt flying team show the jet making head-spinning turns that older jets could never hit.
In 2015, the test pilot’s write up of the jet’s combat performance obliterated the idea of F-35 as a capable dogfighter due to a glaring flaw: Weak maneuverability.
“Overall, the most noticeable characteristic of the F-35A in a visual engagement was its lack of energy maneuverability,” the pilot wrote.

“The F-35 was at a distinct energy disadvantage in a turning fight and operators would quickly learn it isn’t an ideal regime… Though the aircraft has proven it is capable of high AOA [angle of attack] flight, it wasn’t effective for killing or surviving attacks primarily due to a lack of energy maneuverability,” he continued.
Furthermore, according to the pilot, there was basically nothing the F-35 could do to escape getting killed by the F-16’s gun. Any move he tried to escape the F-35’s cannon read as “predictable” and saw the pilot taking a loss.
But the F-35 program and its role in dogfights hadn’t been as well figured out back then.
Since then, the F-35 has mopped up in simulated dogfights with a 15-1 kill ratio. According to retired Lt. Col. David Berke, who commanded a squadron of F-35s and flew an F-22 — the US’s most agile, best dogfighter — the jet has undergone somewhat of a revolution.
New moves, new rules
In the video, the F-35 pilot takes the plane inverted, hits a tight loop, and appears to pause in mid-air as he enters a flat spin that makes his hundred-million-dollar jet appear like a leaf floating down towards earth. (Really better to watch than read about it.)
The flat spin move is often used by F-22 and Russian fighter pilots to show off the intense ability of their planes to sling the nose around in any direction they wish.
According to Berke, this F-35 stunt “demonstrates what the pilots and the people around the aircraft have always known: It’s vastly superior to almost anything out there,” in terms of agility.
Furthermore, according to Berke, an F-16 could not hit the move shown in the demo team’s video.
Berke and others close to the F-35 program have described to Business Insider a kind of breakthrough in the maneuvering of the F-35 throughout its development.
Berke said the video proves that the F-35 is a “highly maneuverable, highly effective dogfighting platform,” but even still, he wouldn’t use that exact maneuver in a real dogfight.
The flat spin is “not an effective dogfighting maneuver, and in some cases, you would avoid doing that.”

“If me and you were dogfighting and we’re 2 miles away, and I had a wingman 5 miles away, you’d be super slow and predictable and easy for him to find,” due to executing the move, said Berke.
But despite the F-35’s impressive moves and ability to win dogfights, Berke said he’d stay on mission and try to score kills that take better advantage of the jet’s stealth.
“I want to avoid getting into a dogfight, but if I had to I’m going to be able to outmaneuver most other aircraft,” he said.
After all, the F-35’s makers never intended it as a straight World War II-era Red Baron killer, but a rethink of aerial combat as a whole.

Iran’s latest attempt to put a satellite in space in spite of US opposition ended in failure, an Iranian defense ministry official told state media, Reuters reported Sunday.
“It was launched with success and … we have reached most our aims … but the ‘Zafar’ satellite did not reach orbit as planned,” the official told state television Sunday.
The latest failure marks the fourth time in a row Iran has been unable to successfully put a satellite in space.
In January 2019, the Iranian rocket carrying the satellite into space failed to reach the “necessary speed” during the third stage of flight, a senior telecommunications official told state media, the Associated Press reported at the time.
The US has criticized Iran’s efforts, arguing that its satellite program is a cover for the development of long-range ballistic missile technology.
President Donald Trump has said that Iran’s space program could help it “pursue intercontinental ballistic missile capability.” Iran argues that the Simorgh rocket is nothing more than a satellite launch vehicle.
In February of last year, Iran made another attempt. Iran’s foreign minister revealed in an interview with NBC News that it failed as well. He added that his country was looking into the possibility of sabotage after a New York Times report suggested the US could be behind the failures.
Iran tried again in August, but the rocket apparently exploded on the launchpad.
In denying US culpability, Trump inexplicably tweeted out an image of the scorched Iranian launchpad from a classified briefing, a photo that appeared to have come from one of the US’ most secretive spy satellites.
After the second failed test, Dave Schmerler, a senior research associate at the Middlebury Institute of International Studies, told NPR that this is a “trial and error” situation, explaining that “eventually they’re going to get it right.”
Iran managed to put a satellite into orbit in 2009, 2011, and 2012, but lately their efforts have been unsuccessful.
