It’s pretty clear that in today’s military, rifle suppressors are a thing.
Long relegated to James Bond movies and secret squirrel types in the U.S. military, firearms mufflers now are becoming more popular in line units. Infantry leaders are beginning to recognize the benefits of silencers, with their ability to help mask a shooter’s location by suppressing both sound and flash.
Experts also preach that a suppressor makes shooting a lot easier on the trooper by reducing recoil and tamping down the “flinch” reaction that inevitably comes from firing a 165 decibel rifle shot.
“Cans,” as they are colloquially known, reduce an M4 rifle shot’s report an average of about 20 decibels — that’s not enough to “silence” them, but it’s enough to meet hearing safety requirements for government regulators.
But how these little tubes of steel or titanium do what they do has always been a bit of a mystery to most shooters. The internal architecture of the suppressor’s baffles are part engineering mastery, part material science part alchemy and each manufacturer has its own design to get the sound down.
Now, an Alabama-based silencer maker has built his cans with a clear, hardened acrylic that shows in vivid detail exactly what’s going on inside when the smoke and flame eject from the muzzle. And YouTuber SmarterEveryDay took his high speed camera to the range and got some amazing footage of the gas and blast dissipating trough a silencer.
It’s a very cool look at a device silencer expert and current 2nd Marine Division Gunner Christian Wade says “increases the effectiveness of your weapon.”
The P-51 may have been the plane that won the skies over Europe, and the Me-262 and Gloster Meteor may have been the first operational jet fighters on the sides of the Axis and Allies.
But those planes weren’t the fastest. That honor goes to the Me 163 “Komet.”
The Me 163 was short (about 19.5 feet long), with a wingspan of about 30 feet and looks like a miniature version of the B-2 Spirit. It was armed with two Mk 108 30mm cannon intended to rip apart Allied planes and it had a top speed of almost 600 miles per hour.
So, why isn’t it more well-known? Well, for starters, the way the plane got its speed — by using a rocket engine — tended to burn up a lot of fuel. That gave it a little over seven minutes of powered flight. The short flight time meant the Me 163 really didn’t have much range — about 25 miles.
After the fuel ran out, the Me 163 was an armed, fast glider. When it landed, it had to be towed. That meant it was a sitting duck until help arrived, and Allied pilots would just wait for the plane to start gliding down before putting a burst into it.
According to MilitaryFactory.com, despite operating for about 10 months, the Me 163 just didn’t get a lot of kills – anywhere from nine to 16, depending on the estimate. That’s less than one pera month. Furthermore, only one fighter group ever operated the plane, which was also hobbled by a shortage of rocket fuel.
AcePilots.com notes that the Me 163 was also dangerous to fly. The rocket fuel ingredients were very nasty – and when they leaked through the suit, it did bad things to the pilot. It wasn’t unheard of for Me 163s to just explode on landing as residual amounts of fuel would mix.
For all intents and purposes, the Me 163 was a manned, reusable surface-to-air missile that could make two attacks. Eventually, the Nazis decided to just use an expendable rocket instead of a manned plane for these types of missions.
Because of the clandestine nature of spycraft, it’s almost impossible to know if you’re the subject of Chinese espionage, but there are steps you can take to reduce the risk you face.
Based on insider accounts, here’s how you can protect yourself from suspected outlets of Chinese espionage as a US citizen.
Avoid Chinese tech
Bill Bishop, an author who has lived on and off in China for decades and writes the Sinocism newsletter for Axios, tweeted the following: “Entertaining to talk to Chinese engineers with experience with Huawei about whether or not Huawei installs back doors. Unanimous ‘Of course’ followed by ‘how naive are the foreigners who still doubt that.'”
With a camera, microphone, and the logins of its owners accounts, accessing the smarphones of US citizens would be a massive intelligence boon for any nation.
Public naivety comes up again and again in intelligence circles. In May, the US banned all Chinese-made smartphones from the Pentagon, saying devices from Huawei and ZTE “may pose an unacceptable risk to department’s personnel, information and mission.”
If the Pentagon is taking seriously the risk of espionage via Chinese-made phones, maybe savvy US citizens should follow suit.
Don’t bring tech to China
“If you have a security briefing” before heading to China for a company with sensitive information, “you would be told ‘do not take a laptop,'” Bonnie Glaser, director of the China Power Project told Business Insider.
“I once got a security briefing or someone told me ‘do not leave the laptop in your room and take a shower, someone could walk in and download your information and be out,'” said Glaser.
Glaser said it’s common for foreigners staying in a hotel in China to return from the gym or a trip and find “people rummaging around their room.”

China has been “aggressive” about intelligence gathering from government and business officials “for years and years and years, and they are really good at it,” said Glaser.
“Any person who is really dealing with proprietary information, nobody takes a laptop, nobody writes an email. People who are really serious about security will take a burner phone, they would never take their own phone,” said Glaser.
In 2014, the FBI issued a public service announcement warning against being a pawn for Chinese spies. US students are “coming back from an overseas experience saying unusual things happened, offers that didn’t make sense, for money, big favors, positions they really weren’t suited for. And we think a lot of those were pitches or recruitments,” the FBI said.
Wray received considerable backlash for his comments from Asian-American civil rights groups who noted in a letter to Wray that “well-intentioned public policies might nonetheless lead to troubling issues of potential bias, racial profiling, and wrongful prosecution.”
But Wray stood firm in his analysis.
“To be clear, we do not open investigations based on race, or ethnicity, or national origin,” Wray told NBC News. “But when we open investigations into economic espionage, time and time again, they keep leading back to China.”

John Browning’s most famous creation, at least in the United States, is the ubiquitous Model 1911. It’s everywhere, and probably within reach of well more than a few people reading this article. The 1911’s active service life in military organizations is pretty much over. However, another of Browning’s continues to serve — the Model 1919 Machine Gun.
The Model 1919 was essentially an air-cooled Model 1917. It was chambered in the powerful and effective .30-06 round, modernized following extensive ballistic testing in the post-World War I years. Unlike most ground-mounted WWI-era machine guns, the 1919 was air cooled, had a heavier barrel, and was easier to maintain under combat conditions than its water-cooled cousins.
It didn’t require all the accouterments of a water-cooled gun, such as a bulky water jacket, water, and a condensing can. The 1919 was originally fed by a cloth belt and designed for vehicles—or a very solid (and heavy) tripod. It had a reasonable rate of fire at 500 rounds per minute on average. By WWII, it was the standard U.S. light machine gun, serving alongside Browning’s M1917 and the legendary Browning M2 HMG.
Like most of Browning’s designs, the 1919 was very reliable for the day and age in which it was produced (insert Glock joke here). It was also apparent early on that the 1919 was versatile. By the end of WWII, it was mounted on tanks, in aircraft, and found in various calibers, including .303 British. It served in virtually every Allied army, and if you dig hard enough, you can even find pictures of enemy troops using captured 1919s. It was very effective against personnel, and when loaded with armor-piercing ammunition, it was also effective against thin-skinned armored vehicles.
In the air, the modified M1919 was called the ANM2. This variant was specifically modified for aerial warfare, boasting a blistering rate of fire at 1,200-plus rpm. The improvements in aircraft technology and design during the period meant rifle-caliber machine guns were only effective when their throw weight could be boosted by increased rates of fire, and by mounting anywhere from two to six of the guns. Feeding them with the most destructive type of ammunition available, generally one form or another of API-T (Armor Piercing Incendiary Tracer), helped.
While the ANM2 served valiantly, it was not as effective as its Browning M2 brethren as an anti-aircraft machine gun. In the decade before WWII, fighter aircraft were increasingly fitted with heavier machine guns, generally .50 BMG Browning variants in the U.S., or 20mm (or larger) cannons in Europe. It wasn’t the fault of the ANM2 that it was less effective against aircraft; it was the fault of the ordnance officers who decided to mount it in aircraft in the first place.
In the infantry role, the M1919 was successful within its limitations. Keep in mind the M1919 was designed in an era when the belt-fed machine gun was essentially a static weapon. The exception to this trend at the time was the MG08/15, which was an intentional departure designed specifically to make the infantry machine gun more portable and useful. By WWII, the MG08/15 concept (a highly mobile, portable general-purpose machine gun [GPMG]) evolved into the MG34 and eventually the MG42 in German service. This is where the M1919’s combat failings became apparent.
Although accurate, reliable, and possessing a good sustainable rate of fire, it was clumsy and awkward on a mobile battlefield compared to the MG34 and MG42. The tripod was large and unwieldy, and it was not always easy to emplace. U.S. troops frequently had to improvise with the 1919, more or less propping it up against or on the WWII equivalent of “a rock or something” when the tripod simply wouldn’t work under the conditions.
As a result, the M1919A6 was developed. This variant added a buttstock and a bipod to the M1919 in attempt to turn it into a light machine gun, more like the MG34 or MG42. However, it was still about a pound heavier than the standard M1919 without the tripod, weighing in at 32 pounds. It was an improvised solution akin to adding a bipod and a buttstock to a boulder. It was still awkward; although it was a bit less unwieldy and more stable, it appeared far too late in the war to have much of an impact.
Again, don’t blame the gun, blame the ordnance weenies.
Until the M60 (a less-than-fantastic GPMG, but a product of the “made here” school of ordnance development) was made widely available during the Vietnam War, the U.S. infantry were saddled with the M1919 and M1919A6 combination.
As a vehicle-mounted machine gun, the 1919 excelled. As a matter of fact, it does such a good job it’s still in service in many places across the globe. It’s been modernized, now using disintegrating link belts instead of old-fashioned cloth belts. Most 1919s still in service were converted to 7.62 NATO, as well, to ease the strain on logistics. Notably, however, one 1919 variant, the M37 Coaxial MG, was somewhat notoriously problematic, again mostly because some people just can’t resist fixing something that works.
There have been some interesting variants of the 1919 over the years. Several ANM2s were converted into a variant called the Stinger. The Stinger was basically a scavenged aircraft-mounted gun with a bipod, carry handle, and buttstock. The extremely high rate of fire was welcomed (for the six or so guns which appear to have actually made it into combat), but the Stinger only served in limited numbers. Its primary claim to fame was being the weapon “Terrible” Tony Stein used during the combat action that earned him a Medal of Honor on Iwo Jima.
If you ever get a chance to fire a ground-mounted M1919, we highly recommend you do so. As it was originally designed, it’s accurate, reliable, and very easy to shoot. As a machine gun for a fixed position, it can easily hold its own against any gun of its era. It’s easy to manipulate, strip, and clean, and it’s very robust in its most common and most current variant, the 1919A4. However, remember it’s almost a 100-year-old design; don’t expect it to perform like a modern machine gun.
This is perhaps the oldest of the UAV-mounted weapons, making its debut off the MQ-1 Predator. With a range of five miles and a 20-pound high-explosive warhead, the Hellfire proved to be very capable at killing high-ranking terrorists — after its use from the Apache proved to be the bane of enemy tanks.
2. GBU-12 Paveway II
While the 2,000-pound GBU-24 and GBU-10 got much more press, the GBU-12 is a very important member of the Paveway laser-guided bomb family. Its most well-known application came when it was used for what was called “tank plinking” in Desert Storm. GBU-12s, though, proved very valuable in the War on Terror, largely because they caused much less collateral damage than the larger bombs.
3. GBU-38 Joint Direct Attack Munition (JDAM)
This is the 500-pound version of the JDAM family. While it has a larger error zone than the laser-guided bombs, it still comes close enough to ruin an insurgent’s day. The GPS system provides a precision option when weather — or battlefield smoke — makes laser guidance impractical.
4. AGM-176 Griffin
This missile has longer range and a smaller warhead, but it still packs enough punch to kill some bad guys. The Griffin has both a laser seeker and GPS guidance. In addition to blasting insurgents out of positions with minimal collateral damage, Griffin is also seen as an option to dealing with swarms of small boats, like Iranian Boghammers.
What’s old is new again. So it is with rye whiskey. In the 17-and-1800s, Bourbon’s spicier, dryer sibling was once the pre-eminent whiskey on this continent. But after prohibition, American’s taste for the stuff waned. Thankfully for the whiskey drinkers of today, times have changed. Our golden age of whiskey has turned back the clock and rye is resurgent. Whiskey, drinkers of all stripes cant seem to get enough of the brown stuff and as their pallets are becoming increasingly adventurous, rye’s spice is becoming more and more a called shot. Not only is it great on the rocks but, rye is killer in a summer cocktail. Whether you like your whiskey neat, on the rocks or in a mixed drink, here are five rye whiskeys to try.
1. Knob Creek Cask Strength Rye
New for this year, Knob Creek Cask Strength Rye was recently named the best in class at the San Fransisco World Spirits Competition. Bottled at 119.6 proof, Knob Creek Cask Strength Rye is quite capable of kicking you in the teeth if you’re not careful, but all that undiluted flavor will also waltz beautifully along your tastebuds. It’s a thick, rich mouthful with spicy, peppery notes playing off a deeply satisfying caramel sweetness.
Best Enjoyed: With a couple of cubes.
2. Willet Family Estate Single Barrel Rye
Well-balanced and richly complex, Willet rye never fails to impress. It’s peppery spice is enhanced with deep rich dark fruit flavors. It can be a bit tough to find, so if you come across it a retail, stock up… and give us a shout, so we can replenish our bar.
Best Enjoyed: In a Manhattan. While great on the rocks, the Willet’s thick, cherry richness can elevate an ordinary Manhattan to the level of craft cocktail.
3. Rittenhouse Rye Bottled in Bond
If you’re totally unfamiliar with rye, Rittenhouse is the place to start. Long a bartender favorite, Rittenhouse is not quite a spicy as some but still has tons of flavors to discover, citrus, vanilla and chocolate to name a few.Bottled at 100 proof, Rittenhouse easily stands out in a substantially iced cocktail.
Best Enjoyed: You can sip this one, but where it really shines is in a cocktail like an Old Pal. At under $30, this is a great rye for experimenting.
4. High West Double Rye
For the last several years, High West has been concocting some of the tastiest and most creative blends on the market. But until recently, they weren’t making their own spirit to formulate their creations. Finally the first batch from their new distillery is ready and High West has incorporated it into the latest release of their Double Rye. It’s a spice-forward whiskey with notes of honey, mint a cinnamon.
Best Enjoyed: We love the Double Rye in cocktails. It makes a great Old Fashioned but if you’re feeling a little more adventurous and up for pounding a few ice into pellets, try it in a rye mint julep.
5. Lock Stock and Barrel 16 Year Rye
Made from a mash of 100% rye, Lock Stock and Barrel 16 Year Rye is big, bold and intense. A glass of this rye is so chalked full of flavor, you can get lost in it’s amber waves and before your know it you’re three drinks deep. It’s a pricey indulgence, but it’s one of the best bottles you’re likely to try, if you can find it.
Best Enjoyed: Sip it… Slowly.

NASA’s Dawn spacecraft has gone silent, ending a historic mission that studied time capsules from the solar system’s earliest chapter.
Dawn missed scheduled communications sessions with NASA’s Deep Space Network on Oct. 31, 2018, and Nov. 1, 2018. After the flight team eliminated other possible causes for the missed communications, mission managers concluded that the spacecraft finally ran out of hydrazine, the fuel that enables the spacecraft to control its pointing. Dawn can no longer keep its antennas trained on Earth to communicate with mission control or turn its solar panels to the Sun to recharge.
The Dawn spacecraft launched 11 years ago to visit the two largest objects in the main asteroid belt. Currently, it’s in orbit around the dwarf planet Ceres, where it will remain for decades.
“Today, we celebrate the end of our Dawn mission – its incredible technical achievements, the vital science it gave us, and the entire team who enabled the spacecraft to make these discoveries,” said Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate in Washington. “The astounding images and data that Dawn collected from Vesta and Ceres are critical to understanding the history and evolution of our solar system.”
Dawn launched in 2007 on a journey that put about 4.3 billion miles (6.9 billion kilometers) on its odometer. Propelled by ion engines, the spacecraft achieved many firsts along the way. In 2011, when Dawn arrived at Vesta, the second largest world in the main asteroid belt, the spacecraft became the first to orbit a body in the region between Mars and Jupiter. In 2015, when Dawn went into orbit around Ceres, a dwarf planet that is also the largest world in the asteroid belt, the mission became the first to visit a dwarf planet and go into orbit around two destinations beyond Earth.
“The fact that my car’s license plate frame proclaims, ‘My other vehicle is in the main asteroid belt,’ shows how much pride I take in Dawn,” said Mission Director and Chief Engineer Marc Rayman at NASA’s Jet Propulsion Laboratory (JPL). “The demands we put on Dawn were tremendous, but it met the challenge every time. It’s hard to say goodbye to this amazing spaceship, but it’s time.”
The data Dawn beamed back to Earth from its four science experiments enabled scientists to compare two planet-like worlds that evolved very differently. Among its accomplishments, Dawn showed how important location was to the way objects in the early solar system formed and evolved. Dawn also reinforced the idea that dwarf planets could have hosted oceans over a significant part of their history – and potentially still do.
“In many ways, Dawn’s legacy is just beginning,” said Principal Investigator Carol Raymond at JPL. “Dawn’s data sets will be deeply mined by scientists working on how planets grow and differentiate, and when and where life could have formed in our solar system. Ceres and Vesta are important to the study of distant planetary systems, too, as they provide a glimpse of the conditions that may exist around young stars.”
This photo of Ceres and one of its key landmarks, Ahuna Mons, was one of the last views Dawn transmitted before it completed its mission. This view, which faces south, was captured on Sept. 1, 2018, at an altitude of 2220 miles (3570 kilometers) as the spacecraft was ascending in its elliptical orbit.
Because Ceres has conditions of interest to scientists who study chemistry that leads to the development of life, NASA follows strict planetary protection protocols for the disposal of the Dawn spacecraft. Dawn will remain in orbit for at least 20 years, and engineers have more than 99 percent confidence the orbit will last for at least 50 years.
So, while the mission plan doesn’t provide the closure of a final, fiery plunge — the way NASA’s Cassini spacecraft ended in 2017, for example — at least this is certain: Dawn spent every last drop of hydrazine making science observations of Ceres and radioing them back so we could learn more about the solar system we call home.
The Dawn mission is managed by JPL for NASA’s Science Mission Directorate in Washington. Dawn is a project of the directorate’s Discovery Program, managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama. JPL is responsible for overall Dawn mission science. Northrop Grumman in Dulles, Virginia, designed and built the spacecraft. The German Aerospace Center, Max Planck Institute for Solar System Research, Italian Space Agency and Italian National Astrophysical Institute are international partners on the mission team.

With a $716 billion budget and the mission to be the best at everything, the Pentagon finds some pretty creative ways of going about it. No, they didn’t have an actual underground boxing club among the military’s highest-ranking chiefs at the Pentagon (that we know of), but they did have some experiments that could have proven fruitful in giving America’s enemies a black eye.
The only problem is that Congress found out about it. That’s why the first rule is not to talk about it.
The Mantis Shrimp, club cocked (more on that later).
In 2015, Arizona Sen. Jeff Flake decided he was going to take on wasteful spending, releasing a “Wastebook” that detailed what he believed was government spending run amok.
Quoting the movie Fight Club, Flake says,“We buy things we don’t need with money we don’t have,” in the Wastebook, which is titled The Farce Awakens. Flake is referring to a 6,800 research grant given to Duke University researchers, who allegedly used it to pit 68 Panamanian mantis shrimp against each other to see who would win and why.
“To see so much money so outlandishly wasted, it’s clear that Washington’s ballyhooing over budget austerity is a farce,” Flake said. “Hopefully, this report gives Congress – which only ever seems to agree when it comes to spending money – something to Chewie on before the taxpayers strike back.”
This is the cover of the wastebook, no joke.
But the study wasn’t really useless, as it turns out. In fact, there’s an entire field of science called biomimetics dedicated to the idea of solving human problems with abilities and designs from animals found in nature. Duke University was doing research in just that vein. So far, they’ve been able to harness the mantis shrimp’s weapons and armor for human needs. It turns out the mantis shrimp (neither mantis nor shrimp) is one of the ocean’s premier brawlers.
The study didn’t really spend 0,000 on a fight club of shrimp. The grant covered the entire span of research on the mantis shrimp. What they discovered is a roving tank on the ocean floor. Its two main appendages act as underwater clubs to knock its prey out in a single punch – and that punch is what had the researchers so fascinated.
Did you see that? I doubt it. Read on!
The mantis shrimp punch goes from an underwater standing start to 50mph in the blink of an eye. It generates 1,500 newtons of force, the equivalent of a 340-pound rock hitting you in the face. If a human could manage 1/10th of that force with its arms, we’d be chucking baseballs into low Earth orbit. To top it all off, those clubs pop out with the velocity of a .22-caliber bullet (one that isn’t underwater) and the sudden change in water pressure causes the water around them to boil at several thousand degrees Kelvin. If the punch doesn’t kill the prey, the punch’s shockwave still can.
But wait, there’s more.
The researchers also wanted to know how mantis shrimp defend against this kind of attack – how their natural armor protects them from other mantis shrimp super weapons. This punch goes right through the shells worn by crabs and clams as well as the natural protections of some species of fish (and aquarium glass, FYI. In case you’re thinking you want one). The clubs themselves are also intensely durable, maintaining their performance throughout the mantis shrimp’s lifespan.
Its primary weapon is a complex system of three main regions, all lightweight and durable, tougher than many engineered ceramics. Civilian applications could improve the performance of cars and airplanes while military applications include body armor and armor for vehicles and potentially aircraft.
“That’s the holy grail for materials engineers,” said University of California professor and researcher David Kisailus, who is pioneering such studies these days.
In the early years of the Cold War, huge propeller-driven bombers began to give way to bombers equipped with jet engines. These first jet bombers, like the Boeing B-47 Stratojet, had performance, but very short range. The first B-47s entered service in 1950.
The Soviet Union answered the B-47 with the Tupolev Tu-16 bomber, code-named Badger by the North Atlantic Treaty Organization. This plane entered service in 1954, eventually proved to be a versatile airframe, and included tanker, reconnaissance, and electronic warfare versions. While the United States didn’t export the B-47, the Soviets had no compunctions when it came to exporting its jet-powered medium bomber. The fall of the Soviet Union saw the Badger and its variants retire in 1998.
One of those potential export customers was the People’s Republic of China. The Soviets had even sent some kits for China to assemble the plane locally (something also done with the MiG-15, MiG-17, MiG-19, and MiG-21). According to MilitaryFactory.com, some Soviet-built examples entered service in 1959 as the Xian H-6. Reflecting the fact that it is a Chinese copy of the Soviet plane, NATO calls the H-6 the Badger.
Then came the break-up of the Sino-Soviet friendship. Suddenly, China had to spend time reverse-engineering the Badger. Eventually, they were able to produce as many as 180 of their own. China’s newest variants have longer range and are optimized more for the cruise-missile shooter role.
The H-6 can reach a top speed of 652 miles per hour, and has a range of 3,728 miles. The plane can carry up to 20,000 pounds of bombs, or it can carry C-601, C-602, or KD-88 missiles. China has been introducing newer versions of this bomber in recent years, and even made some exports of their own!
You can see more about this bomber in the video below.
U.S. Air Force officials are looking to upgrade the B-52 Stratofortress‘ bomb load at a time when the service, and the Defense Department as a whole, is preparing for near-peer rivals.
In June 2018 the service posted a request for information survey to identify potential contractors that could offer insights on how to best integrate newer and much heavier bombs under the aircraft’s wings.
Given that the aircraft is expected to fly for another 30 years, the potential upgrade — part of the Heavy Weapon Release Pylon Program — speaks to the Air Force’s initiative to stay ahead of emerging threats, particularly aggressors in the Pacific, according to a service official.
“This is not a requirement that came out of nowhere,” the service official told Military.com on background July 9, 2018. “There are compelling reasons for why we have to go down that road.”
While specific munitions haven’t been advertised, the goal is to quadruple the bomb size. Officials want pylons “capable of carrying multiple weapons in the 5,000-lb to 20,000-pound weight class,” according to the RFI. The current common pylon maximum is for 5,000-pound munitions.
A B-52 Stratofortress
The external pylon “was designed in 1959 and has been in service since the 1960s. When it was introduced, there wasn’t a requirement nor did anyone foresee a need to carry weapons heavier than 5000 lbs,” the RFI states.
According to the 2018 NDS, “China is a strategic competitor using predatory economics to intimidate its neighbors while militarizing features in the South China Sea.
“It is increasingly clear that China and Russia want to shape a world consistent with their authoritarian model — gaining veto authority over other nations’ economic, diplomatic and security decisions,” the NDS says.
Air Force Secretary Heather Wilson has on multiple occasions referenced China’s quick pace in technological development, which is driving the service to react. There has been explicit recognition “of the re-emergence of great power competition,” she has said.
“[China] is modernizing very quickly. They’re modernizing their air defenses, but also their air-to-air capability is really modernizing across the board. It is the pacing threat for the U.S. Air Force because of the pace of their modernization,” she told reporters at the Pentagon in February 2018.
The official also pointed to the bomber road map, which enhances the B-52 aircraft as a whole.

The move marked a significant shift to bring back the B-52H, which previously filled the continuous bomber presence mission from 2006 to 2016 before the B-1 briefly took over.
Bringing the B-52 back meant putting a nuclear-capable bomber in theater at a time when relations between the U.S. and North Korea were largely unpredictable, and as China continued to flex its muscles in the South China Sea.
“Nothing wrong with competition, nothing wrong with having strong positions, but when it comes down to introducing what they have done in the South China Sea, there are consequences,” Mattis said.
As for the B-52 bomb pylon upgrade, the program is in the early stages.
The RFI “is only for market research of possible contractor sources,” said Stephen Palmer, a contracting officer with Air Force Life Cycle Management Center who specializes in the B-1 Lancer and B-52 programs at Tinker Air Force Base, Oklahoma.
“[We] are not asking for any contractor to provide a proposal at this time,” he said in an email.

Getting supplies to Marines ashore is growing more complex as new threats reach the space between ships and the beach, so leaders are looking to high-tech self-driving ships to get the job done.
The Navy’s mysterious 132-foot-long autonomous Sea Hunter vessel could move fuel, ammunition, and other heavy supplies from large ships out to small teams of Marines, sea service leaders said May 8, 2019, at the Sea-Air-Space expo outside Washington, D.C.
“If we can do what we’ve demonstrated with Sea Hunter … with logistics, to program that connector to meet that force at a location to sustain them and provide them with what they need, that is where we’re going to have to practice, practice, practice and learn and adapt our structure to be responsive to that,” said Rear Adm. Jim Kilby, director of warfare integration.

Marines and sailors recently practiced sustaining ground troops operating at various points ashore during amassive amphibious exercise called Pacific Blitz. During that exercise, it became clear they must leverage the distance unmanned vessels can travel without risk to personnel, Brig. Gen. Stephen Liszewski, director of operations for Marine Corps Plans, Policies and Operations, told Military.com.
“The unmanned piece is the untapped potential,” Liszewski said. “We know that is one way we can get after this ability to operate in a more distributed and lethal environment.”
Ideally, the services would use a mix of drone aircraft and unmanned ships to get the job done, he added. There are times when they’ll need the speed and range of unmanned aircraft, he said, but they can’t carry everything.

“With a surface connector, you’re going to be able to move larger volumes of things, particularly if you’re talking ammunition or bulk liquids like water or fuel,” Liszewski said. “Clearly, aviation speed or range is what you get, but it’s not one or the other. You’ve got to have both [surface connectors and air assets].”
Though it gets a lot of attention, Tesla isn’t the only company creating electric cars.
Some traditional carmakers like Aston Martin and Porsche are exploring the rapidly-growing electric car field with super powerful new models which add their own flair for luxury and speed to the market.
Meanwhile, other much smaller companies are exploring the high-end electric sector, such as the relatively unknown Aspark — which hasn’t even released a production vehicle yet.
Horsepower is measured a little differently for electric cars, as an electric motors’ full torque is deployed as soon as the driver steps on the accelerator. That means an electric car can feel more powerful than an internal-combustion-engined (ICE) car with the same horsepower rating at the low end, but start to lose some of its gusto at sustained high speeds unlike a gas-powered car.
With that crucial difference in mind, here are 11 of the most powerful electric cars money can buy, including some that are setting world records.
1. Nio EP9
Nio has been called the “ Tesla of China.” With the EP9 supercar, it’s obvious the company means business.
The car has a top speed of 195 mph and horsepower rating of 1,341, giving it a zero-to-60 time of only 2.7 seconds. Nio boasts the car has double the downforce of a Formula One racecar and delivers a F-22 fighter pilot experience by cornering at 3G.
The EP9 has a range of 265 miles before needing a new charge, and a full charge takes 45 minutes. The car also has an interchangeable battery system that takes 8 minutes to swap.
At least six of the 16 produced units have been sold to investors at id=”listicle-2639641248″.2 million each.

2. Tesla Model S Performance
Tesla no longer boasts the horsepower ratings for its cars, but the ,990 Tesla Model S Performance is plenty powerful. It can propel its nearly 5,000-pound frame to 60 mph in just 2.4 seconds. Tesla says its top speed is 163 mph and it carries an average range of 345 before complete discharge.
Owners can recharge at the company’s Supercharger locations, where 15 minutes is good for 130 miles in optimal conditions.
3. Rimac’s Concept One and C_Two
Rimac’s Concept One, which debuted in 2011, has a rating of 1,224 horsepower, allowing it to reach top speeds of 220 mph and hit 62 mph from a standstill in just 2.5 seconds. The nearly id=”listicle-2639641248″ million supercar’s 90 kWh battery pack gives it a 310-mile range.
Rimac made only 88 units of the supercar, and British TV personality Richard Hammond famously crashed one in 2017.
The supercar can be charged 80% in 30 minutes when it’s connected to a 250 kW fast-charging network. It also includes a list of driver assistance systems, such as facial recognition to open doors and start the engine. It can also scan your face to determine your mood, and if the C_Two determines emotion s such as stress or anger, it will start playing soothing music.
The Genovation GXE is a converted all-electric Chevy Corvette with a horsepower rating of 800. It currently holds the record for “fastest street-legal electric car to exceed 209 mph,” but the company claims it can even get to 220 mph. It can go zero-to-60 mph in under three seconds.
This new Roadster will be able to hit top speeds of over 250 mph, and 60 mph in 1.9 seconds, Tesla says. There’s also a removable glass roof that stores in the trunk, turning the car into a convertible.
The 0,000 car also will have a 620-mile range, the longest of any on our list.
The company is now taking reservations for 2020 delivery.
6. Aspark Owl
The Aspark Owl, a 1,150 horsepower supercar, will be able to reach 174 mph and have a 180-mile range. The Owl recently hit 62 mph in 1.9 seconds, although it’s still in testing.
Formally known as the Mission E, the Taycan will be Porsche’s first fully-electric car. Porsche initially had a target of 20,000 units for its first year of production, but it recently doubled this number due to interest, and the company already has more 30,000 reservations, it recently revealed.
The Taycan has a horsepower rating of over 600 that allows it to travel zero-to-60 mph in under 3.5 seconds. The car also has a range of 310 miles on a single charge and can get 60 miles of range from just four minutes of charging.
Lotus’ Evija is poised to be the first fully-electric British hypercar. The company will fully reveal the Evija during Monterey Car Week starting Aug. 9, 2019.
Although the company has not released final specifications, its target is 2,000 horsepower, which would be good for a zero-to-62 mph acceleration time of under three seconds and a top speed of around 200 mph, according to CNET.
The car will cost around million and 130 units will be made.

Snipers specialize in taking out enemy personnel from well beyond the average grunt’s range. Lately, due to advances in technology and an amazing degree of skill, the distances from which snipers are scoring kills are getting longer and longer. In 1967, Carlos Hathcock set a record, recording a kill from 2,500 yards using a modified M2 heavy machine gun. But in the War on Terror, four snipers proceeded to shatter the record set by “White Feather” Hathcock.
Of those four record-snapping snipers, three of them (Master Corporal Arron Perry, Corporal Rob Furlong, and an unidentified member of Combined Joint Task Force 2) used the same rifle: The McMillan Tac-50. This gun is chambered for the .50 BMG round — the same round used by the legendary Ma Deuce.
The McMillan Tac-50.
According to the manufacturer, the Tac-50 uses a five-round detachable box magazine. The rifle has a 29-inch, match-grade, free-floating, hand-lapped, and fluted barrel. Most versions of the rifle are equipped with a bipod to provide a fixed length of pull. The rifle comes in one of five finishes: black, olive, gray, tan, or dark earth.
So, how did a cartridge full of .50 BMG, a caliber once used to kill tanks and aircraft, end up on sniper rifles? The answer lies in the round. All three of the McMillan Tac-50 snipers used the Hornaday A-Max match-grade bullet. In .50 BMG, this bullet weighs barely 750 grains — or about 1.7 ounces — meaning it can be flung amazing distances.

Here’s something else interesting: There’s a civilian version of this rifle available for sale. Yes, it’ll have to be shipped to your local Federal Firearms License-holder and you’ll have to go through a background check, but this long-range shooter is available. You can also get the Hornaday rounds as well.
One thing is for certain: It would be fascinating to see what Hathcock could’ve done with this rifle.
