Venezuela and the United States didn’t always have such a contentious relationship. The country was traditionally awash with funds from oil sales, and when you have that kind of cash, everyone wants to be your friend. In 1982, Venezuela signed a deal for fifteen F-16A and six F-16B fighter aircraft from the U.S.
The country would need them just a few years later.
The threat to Venezuela’s government didn’t come from an external invader, it came from within. In 1992, the Revolutionary Bolivarian Movement attempted to overthrow the government of Carlos Andres-Perez, who survived two such attempts in just a year’s time. Both were led by a guy named Hugo Chavez, whose supporters were angry about the country’s outstanding debt and out-of-control spending.
TFW you’re about to run South America’s richest economy into the ground.
Venezuelan armed forces, under the command of Lt. Col. Hugo Chavez, launched two coup attempts in 1992. The second coup, which took place in November of that year, saw leaders from the Air Force and Navy take command while Chavez was still in prison for the first attempt. They learned from the mistakes of the previous attempt and seized major air bases — but not all of the pilots.
Chavez’ rebels used OV-10 Broncos to support rebel operations, but loyalist pilots were already in the air and they were flying F-16s. That’s what led to the confrontation below, filmed on the ground by a civilian.
The video above shows a government F-16 turning into the Bronco before hitting its speed brakes and firing its 20mm cannon. The burst sent the OV-10 down in flames. There’s another angle of the dogfight, taken by a local news crew.
Though both of the coups failed, Chavez ultimately became president, but through legitimate means in 1998. He won the Venezuelan presidency with 56 percent of the vote. After his election, Venezuela’s relations with the United States soured and the country could no longer maintain its fleet of F-16s due to an arms embargo slapped on by the administration of George W. Bush.
Now, the Venezuelan Air Force relies on the Russian-built Sukhoi-30 multirole fighter for the bulk of its fighter missions. It still has at least 19 F-16s, but has little capacity to care for the aging aircraft.
Okay, you’ve heard all the complaints about the F-35. It’s super-expensive. It’s got problems getting ready for combat. But in the real world, there’s no other option. And as WATM has already explained, the Marine Corps desperately needs to replace its F/A-18 Hornets.
But suppose, instead of blowing their RD money on the F-35, the Air Force, Navy, and Marines had decided to pull out File A56-7W and instead replicate Airwolf? They’d have gotten a much better deal – and it might even have helped the Army, too.
Airwolf’s specs (click here for another source) reveal this helicopter already took advantage of some stealth technology, had modern ECM systems and sensors, and very heavy armament (four 30mm cannon, two 40mm cannon, and various air-to-air and air-to-ground missiles). All in all, it’s very powerful, even if it was the brainchild of one of the big TV showrunners of the 1980s and 1990s.
So, why does it beat the F-35? Here are some of the reasons.
1. It can operate off any ship
With a top speed of over Mach 2, Airwolf may have the performance of a fighter jet, but it takes off and lands like a helicopter – without the need for the complex mechanisms used on the V-22 Osprey.
Think of it this way; with Airwolf in its hanger deck every surface combatant and amphibious ship could carry what amounts to a Generation 4.5 fighter. Even the Littoral Combat Ships could handle Airwolf, giving them a lot more punch in a fight than they currently have.
2. It would replace more airframes than the F-35 would
The F-35 is replacing the AV-8B Harrier, F/A-18 Hornet, F-16 Fighting Falcon, and A-10 Thunderbolt II in U.S. service. Airwolf not only would replace all four of those airframes, but it would also replace all of the AH-1 and AH-64 helicopters in Marine Corps and Army service. The promise of the TFX program as originally envisioned in the 1960s could be fulfilled at last!
3. Better performance
According to an Air Force fact sheet, the F-35 has a top speed of Mach 1.6, a ceiling of 50,000 feet, and a range of 1,350 miles without refueling. Airwolf hits a top speed of Mach 2, a ceiling of 100,000 feet, and a range of 1,450 miles.
In other words, Airwolf would have the F-35 beat in some crucial areas. Now, the F-35 might have an advantage in terms of payload (fixed-wing planes usually have that edge), but the fact remains, Airwolf would have been a very viable candidate for that competition – and might have had the edge, given that the Army would have bought airframes to replace the Apache.
Oh, and here’s the Season 1 opener, just for kicks:
Researchers from MIT and NASA have developed an airplane wing that can change shape and increase the efficiency of aircraft flight, production, and maintenance, according to MIT News.
On a traditional airplane wing, only parts of the wing, such as flaps and ailerons, can move to change the plane’s direction. The wing designed by the MIT and NASA researchers would be able to move in its entirety.
The wing is made of hundreds of small, identical pieces that contain both rigid and flexible components which make it lighter and more efficient than traditional airplane wings. Since the wing could adjust to the particular characteristics of each stage of flight (takeoff, landing, steering, etc.), it could perform better than traditional wings, which are not designed to maximize performance during any part of a flight.
Wing assembly under construction.
“We’re able to gain efficiency by matching the shape to the loads at different angles of attack,” NASA research engineer Nicholas Cramer told MIT News.
The wing’s parts are arranged in a lattice structure that creates a large amount of empty space and covered in a thin, polymer material. Combined, the wing’s materials and structure make it as firm as a rubber-like polymer (though much less dense) and as light as an aerogel.
MIT graduate student Benjamin Jenett told MIT News that the wing performed better than expected during a test in a wind tunnel at NASA’s Langley Research Center in Virginia.

Adding large numbers of new next-generation destroyers will substantially change the Navy’s ability to conduct major maritime warfare operations by enabling surface forces to detect enemy attacks at much farther distances, launch long-range strikes with greater precision and destructive force, and disperse offensive forces across much wider swaths of ocean.
The US Navy has awarded deals for 10 new high-tech DDG 51 Flight III Destroyers and built in options to add even more ships and increase the “build rates” for construction of new warships — all as part of a massive strategic push to accelerate fleet growth and usher in a new era of warfighting technology for the Navy.
Six of the new destroyers will be built by Huntington Ingalls Industries in a billion deal, and four of them were awarded to General Dynamics Bath Iron Works for .9 billion, according to a Navy announcement. The acquisition is a multi-year procurement intended to reach from this year through 2022.
“We also have options for an additional five DDG 51s to enable us to continue to accelerate delivery of the outstanding DDG 51 Flight III capabilities to our Naval force,” James F. Geurts, assistant secretary of the Navy for research, development and acquisition, said in a written Navy statement.
Meanwhile, the Navy has now started construction on its first new Flight III DDG 51 surface warfare destroyer armed with improved weapons, advanced sensors and new radar 35-times more sensitive than most current systems, service officials announced.
USS Cole and two other Arleigh Burke-class vessels docked at Naval Station Norfolk in July 2009.
Construction of the first DDG-51 Arleigh Burke-class Flight III Destroyer is part of a sweeping Navy and Pentagon effort to speed up delivery of new warships and expand the surface fleet to 355 ships on an accelerated timeframe.
Navy Flight III Destroyers have a host of defining new technologies not included in current ships such as more on-board power to accommodate laser weapons, new engines, improved electronics, fast-upgradeable software, and a much more powerful radar. The Flight III Destroyers will be able to see and destroy a much wider range of enemy targets at farther distances.
In fact, a new software and hardware enabled ship-based radar and fire control system, called Aegis Baseline 10, will drive a new technical ability for the ship to combine air-warfare and ballistic missile defense into a single system.
The AN/SPY-6 radar, also called Air and Missile Defense Radar, is engineered to simultaneously locate and discriminate multiple tracks.
This means that the ship can succeed in more quickly detecting both approaching enemy drones, helicopters and low flying aircraft as well as incoming ballistic missiles.
The Raytheon-built AN/SPY-6(V) radar is reported by developers to be 35-times more powerful than existing ship-based radar systems; the technology is widely regarded as being able to detect objects twice as far away at one-half the size of current tracking radar.
The farther away ship commanders can see approaching threats, across the spectrum of potential attack weapons, the faster they are able to make time-sensitive decisions about which elements of a ship’s layered defense systems should be used.
The AN/SPY-6 platform will enable next-generation Flight III DDG 51s to defend much larger areas compared with the AN/SPY-1D radar on existing destroyers. In total, the Navy plans as many as 22 Flight III DDG 51 destroyers, according to a previously completed Navy capabilities development document.

The AN/SPY-6 is being engineered to be easily reparable with replaceable parts, fewer circuit boards and cheaper components than previous radars, according to Raytheon developers; the AMDR is also designed to rely heavily on software innovations, something which reduces the need for different spare parts, Navy program managers have announced.
Service officials say the new ship uses newly integrated hardware and software with common interfaces will enable continued modernization in future years. Called TI 16 (Technical Integration), the added components are engineered to give Aegis Baseline 10 additional flexibility should it integrate new systems such as emerging electronic warfare or laser weapons
In early 2018 the ship’s program manager Capt. Casey Moton said that special technological adaptations are being built into the new, larger radar system so that it can be sufficiently cooled and powered up with enough electricity. The AMDR will be run by 1000-volts of DC power.
The DDG Flight III’s will also be built with the same Rolls Royce power turbine engineered for the DDG 1000, yet designed with some special fuel-efficiency enhancements, according to Navy information.
The AMDR is equipped with specially configured cooling technology. The Navy has been developing a new 300-ton AC cooling plant slated to replace the existing 200-ton AC plant, Moton said.
Before becoming operational, the new cooling plant will need to have completed environmental testing which will assess how the unit is able to tolerate vibration, noise and shocks such as those generated by an underwater explosion, service officials said.
DDG 51 Flight III destroyers are expected to expand upon a promising new ship-based weapons system technology fire-control system, called Naval Integrated Fire Control – Counter Air, or NIFC-CA.
The technology, which has already been deployed, enables ship-based radar to connect with an airborne sensor platform to detect approaching enemy anti-ship cruise missiles from beyond the horizon and, if needed, launch an SM-6 missile to intercept and destroy the incoming threat, Navy officials said.
Navy developers say NIFC-CA presents the ability to extend the range of attack missiles and extend the reach of sensors by netting different sensors from different platforms — both sea-based and air-based together into one fire control system.
The system hinges ship-based Aegis Radar — designed to provide defense against long-range incoming ballistic missiles from space as well as nearer-in threats such as anti-ship cruise missiles.
Through the course of several interviews, SPY-6 radar developers with Raytheon have told Warrior Maven that simulate weapons engagements have enabled the new radar to close what’s called the “track loop” for anti-air warfare and ballistic missile defense simulations. The process involves data signal processing of raw radar data to close a track loop and pinpoint targets, Raytheon developers said.
The radar works by sending a series of electro-magnetic signals or “pings” which bounce off an object or threat and send back return-signal information identifying the shape, size, speed or distance of the object encountered.
The development of the radar system is hastened by the re-use of software technology from existing Navy dual-band and AN/TPY-2 radar programs, Raytheon developers added.

AN/SPY-6 technology, which previously completed a Critical Design Review, is designed to be scalable, Raytheon experts say.
As a result, it is entirely plausible that AMDR or a comparable technology will be engineered onto amphibious assault ships, cruisers, carriers, and other platforms as well.
Raytheon statements say AN/SPY-6 is the first truly scalable radar, built with radar building blocks — Radar Modular Assemblies — that can be grouped to form any size radar aperture, either smaller or larger than currently fielded radars.
Raytheon data on the radar system also cites a chemical compound semi-conductor technology called Gallium Nitride which can amplify high-power signals at microwave frequencies; it enables better detection of objects at greater distances when compared with existing commonly used materials such as Gallium Arsenide, Raytheon officials explained.
Raytheon engineers tell Warrior that Gallium Nitride is designed to be extremely efficient and use a powerful aperture in a smaller size to fit on a DDG 51 destroyer with reduced weight and reduced power consumption. Gallium Nitride has a much higher break down voltage so it is capable of much higher power densities, Raytheon developers said.

War is the subject of some of the most powerful movies ever made. But Hollywood has long been borrowing its inspiration from an older medium – books – and its war movies are no exception. While some war movies are original efforts, like 2017’s Dunkirk (though The Miracle of Dunkirk by Walter Lord is a fantastic book on the subject — even if the movie wasn’t based on it), many of the greatest war movies of all time have been based on novels or nonfiction books.
Some of the books that have inspired war adaptations are considered classics, and others are too often overlooked. But all are worth reading, and we’ve brought together some of the very best ones below. Here are the superb books behind some of the best war adaptations Hollywood has ever made.
Craig’s nonfiction account of one of the most dramatic moments of the Second World War was the inspiration for a movie made nearly 30 years after its publication. Enemy at the Gates (2001) used multiple accounts to create its story, but both the movie and this book capture the dark drama and tension of the Battle of Stalingrad.
2. From Here to Eternity by James Jones
From Here to Eternity (1953) is one of Hollywood’s all-time classics, and it owes its existence to the novel of the same name written by James Jones. The story centers around the men stationed at Pearl Harbor and reaches its climax with the infamous surprise attack launched by the Japanese. Themes of love and friendship mix with the horror of the attack in a story that lingers. Jones’ sequel, The Thin Red Line, focuses on a fictionalized battle within the Battle of Guadalcanal and was adapted into a film starring Sean Penn and Adrien Brody in 1998.
3. Casualties of War by Daniel Lang
The roots of Casualties of War (1989) are found in Daniel Lang’s work – not just in his book Casualties of War, but also in the 1969 article he wrote for The New Yorker that eventually led to the full-length work. Like the movie and the article, Lang’s book tells the story of a wartime atrocity committed by American servicemen in Vietnam. The kidnapping, rape, and murder of Phan Thi Mao is difficult to read about and impossible to forget.
4. We Were Soldiers Once… and Young by Lt. Gen. Harold G. Moore and Joseph L. Galloway
We Were Soldiers (2002) is an adaptation of this nonfiction book, widely considered to be one of the great modern military histories ever written. The book is a collaboration between Galloway, a war journalist, and Moore, a lieutenant colonel at the time of the Battle of Ia Drang, which is featured prominently in the book.
War correspondent Richard Tregaskis’ clear, vernacular prose and careful reporting work make his account of his time on Guadalcanal one of the most readable journalistic records of World War II. The book offered insight into the relationship between the Marines on Guadalcanal, and its uplifting moments of camaraderie helped make it popular in the U.S. as the war raged on. It was swiftly adapted into a film, which was also released before the end of World War II.
6. Heart of Darkness by Joseph Conrad
Heart of Darkness is unique on this list in part because it is not, strictly speaking, a war novel. Conrad’s book is about the soul of a man in the in the Congo at the height of colonization. Kurtz, a European ivory trader, has changed dramatically during his years in the jungle. Filmmaker Francis Ford Coppola and screenwriter John Milius saw parallels to the changing souls of men at war and adapted the novella into the classic, Apocalypse Now.
Fascinating, impressive, and sometimes troubling, the autobiography that Chris Kyle wrote with Scott McEwan and Jim DeFelice is an essential documentation of American warrior culture. Kyle is the deadliest sniper in U.S. history, with 160 confirmed kills. Yet some reports have suggested that he embellished his military record in this book, which also led to Kyle losing a defamation lawsuit. Kyle was later killed by a shooter at a civilian gun range, but his book survives as a fascinating primary document – more useful and important, in some ways, than the popular film adaptation.
8. All Quiet on the Western Front by Erich Maria Remarque
All Quiet on the Western Front is a grim and moving novel. It is a fictionalized account of Remarque’s time in the German army late in World War I. Its unflinching portrayal of the evils of war and its underlying tones of survivor’s guilt make it one of the most honest books ever written about war. It’s also one of the best. It was adapted into a film in 1930, which went on to win Academy Awards for Best Director and Outstanding Production.
At the start of Star Wars: The Phantom Menace, two of the villains were arguing about taking on a high-risk mission.
“Send the droid,” one of them says.
Well, if the Army has its way and a new prototype unmanned plane enters the arsenal, “send in the droid” could have a whole new meaning for todays soldiers and other troops.
Over the last few months, the Army has begun preliminary tests on a new prop-driven drone dubbed the Joint Tactical Aerial Resupply Vehicle, or JTARV at Aberdeen Proving Ground and Picatinny Arsenal.
The service realizes resupply convoys can be vulnerable to attack. An Army Research Laboratory release from earlier this month noted that 60 percent of the combat casualties in 2013 occurred during resupply missions. Yet, the resupply of troops is crucial — especially in the heat of combat.
During the 1993 firefight in Mogadishu, for example, helicopters re-supplied the Rangers who were protecting the crash site of Super Six-One at substantial risk.
Had the JTARV prototypes been available, instead of sending manned choppers, a drone could have delivered 300 pounds of ammo and gear (like night-vision devices, grenades, and MREs) without risking a downed crew.
Time to get the supplies? About a half-hour.
See if Domino’s can beat that!
Improved versions of the JTARV could haul even more supplies – about 800 pounds – and take them further, with a total range of 125 miles. This could be very useful for long-range reconnaissance patrols or for resupplying remote outposts like those once manned by soldiers in the Korengal Valley of Afghanistan.
The JTARV is a combined project from SURVICE Engineering Company and Malloy Aerospace. Malloy is a British company which is best known for making the Hoverbike. The Hoverbike is, in essence, a one-person helicopter that can travel about 92 miles, and looks like a very primitive version of the speeder bikes used in Return of the Jedi.
SURVICE Engineering is a Maryland-based defense contractor that has supported research and development for the Pentagon. Located near Aberdeen Proving Ground, SURVICE Engineering has been involved in supporting the development of technology for land combat forces.
The Marine Corps has already been in the unmanned cargo delivery game for a while. An unmanned version of the Kaman K-Max helicopter was used for re-supply missions from December 2011 to May 2014 during Operation Enduring Freedom. The K-Max has a range of 267 miles and can deliver up to 6,000 pounds of cargo while flying at speeds of up to 115 mph.
Boeing has also been developing the H-6U Unmanned Little Bird for this mission as well, trying to leverage the proven track record of the OH-6 Cayuse scout helicopter and the AH-6/MH-6 Little Bird choppers used by the 160th Special Operations Aviation Regiment (the Nightstalkers) in American military service.
The H-6U’s case is also assisted by the widespread ownership of the MD 500 series of helicopters across the globe for both civilian and military applications. This means that spare parts are readily available (not a small consideration for military operations). The H-6U would be faster with a top speed of 175 miles per hour, but could only haul about 1,500 pounds of cargo over the same 267 mile range.
Things are changing, but the one thing that remains the same is the need for the troops to be resupplied. But instead of asking for volunteers, soon a general’s response may well be, “Send the droid.”
Chinese military experts said on Oct.9, 2018, that the H-20 nuclear stealth bomber will soon make its maiden flight.
“The trial flight will come soon,” Song Zhongping, a Chinese military expert, told the Global Times.
The Global Times is under the state-run People’s Daily, and has published hyperbolic articles before, according to The War Zone, but “Song does not officially speak for the Chinese government and his views are his own.”
In August 2018, China Central Television released a documentary disclosing that the H-20 is called Hong-20, meaning “bomber aircraft” in Chinese, Global Times reported.
Zhongping told the Global Times on Oct. 9, 2018, that disclosing the name meant that progress had been made on the Hong-20, and that the bomber’s avionics, hydraulic pressure and electrical supply were probably completed.
Releasing the name might also act as a possible deterrence, Zhongping said. “Usually the development of equipment and weaponry of the People’s Liberation Army is highly confidential.”
B-21 Raider artist rendering.
Indeed, the development and conception of the Hong-20 has been rather murky.
China’s Xi’an Aircraft Industrial Corporation may have begun developing the Hong-20 in the early 2000s, but it was only confirmed by a PLA Air Force commander in 2016.
In 2017, the Pentagon further confirmed that China was “developing a strategic bomber that officials expect to have a nuclear mission,” also noting that “[past] PLA writings expressed the need to develop a ‘stealth strategic bomber,’ suggesting aspirations to field a strategic bomber with a nuclear delivery capability.”
The Hong-20’s specifications are still relatively unknown, but a researcher working with the US Air Force previously told Business Insider that the Hong-20 is a four engine stealth bomber and that the details have not been “revealed except it is to have a dual [nuclear and conventional] role.”
The Hong-20 will also probably carry CJ-10K air-launched cruise missiles, have a range of 5,000 miles and a 10 ton payload, The War Zone reported.
The Asia Times, citing a previous Global Times article, reported that Fu Qianshao, a Chinese aviation pundit, said the goal was for the Hong-20 to have about a 7,500 range and a 20 ton payload.
While the latter estimates may very well be exaggerated, The War Zone reported that a range of 5,000 miles would certainly bolster Beijing’s territorial claims in the South China Sea, and pose a threat to Taiwan and even US carriers in the Pacific.

A former Army vice chief of staff and Fox News analyst will be awarded the nation’s highest civilian honor by President Donald Trump, the White House announced Wednesday.
Retired Gen. Jack Keane, a Silver Star recipient who led troops in Vietnam and was at the Pentagon on 9/11, will be presented with the prestigious Presidential Medal of Freedom next week.
“General Keane has devoted his life to keeping America safe and strong,” a White House statement announcing the award states.
Keane could not immediately be reached for comment.
Bill Hemmer, a Fox News host, on Wednesday called the award well deserved. “Jack Keane, a friend and colleague for years here at Fox … is a committed American to getting it right,” he said.
Presidents select Medal of Freedom recipients. The award was created to honor Americans who have made significant contributions to national, international or cultural causes in the public or private sectors. Recipients have included those in the medical, journalism, entertainment and business fields.
President George H.W. Bush presented the award to Holocaust survivor, author and political activist Elie Wiesel in 1992. Civil rights activist Rosa Parks received the award from President Bill Clinton in 1996. Mother Teresa, a Catholic nun and later saint, was chosen for the award by President Ronald Reagan in 1985 and physicist Stephen Hawking by President Barack Obama in 2009.
The award was most recently presented to conservative radio talk show host Rush Limbaugh during last month’s State of the Union address. Trump took heat for the decision to award the medal to Limbaugh, who is seen as a divisive figure by critics. The talk show host has been accused of making sexist and racist comments on the air.
Keane, 77, retired from the Army in 2003. As vice chief of staff, he provided oversight for the wars in Iraq and Afghanistan, according to his bio. He played a key role in formulating and recommending the surge strategy in Iraq, it states, and as recently as 2016 was still advising senior government officials on national security issues and the Afghanistan War.
Keane also serves as chairman of the board for the Institute for the Study of War, a Washington-based think tank that produces research on military and foreign affairs.
In addition to being awarded the Silver Star, Keane has earned two Defense Distinguished Service Medals, five Legions of Merit, two Army Distinguished Service Medals and the Bronze Star.
“We never dreamt that it would be this clear, this beautiful.”
Physical Scientist J.T. Heineck of NASA’s Ames Research Center in California’s Silicon Valley gets his first glimpse at a set of long-awaited images, and takes a moment to reflect on more than 10 years of technique development – an effort that has led to a milestone for NASA’s Aeronautics Research Mission Directorate.
NASA has successfully tested an advanced air-to-air photographic technology in flight, capturing the first-ever images of the interaction of shockwaves from two supersonic aircraft in flight.
“I am ecstatic about how these images turned out,” said Heineck. “With this upgraded system, we have, by an order of magnitude, improved both the speed and quality of our imagery from previous research.”
One of the greatest challenges of the flight series was timing. In order to acquire this image, originally monochromatic and shown here as a colorized composite image, NASA flew a B-200, outfitted with an updated imaging system, at around 30,000 feet while the pair of T-38s were required to not only remain in formation, but to fly at supersonic speeds at the precise moment they were directly beneath the B-200. The images were captured as a result of all three aircraft being in the exact right place at the exact right time designated by NASA’s operations team.
The images were captured during the fourth phase of Air-to-Air Background Oriented Schlieren flights, or AirBOS, which took place at NASA’s Armstrong Flight Research Center in Edwards, California. The flight series saw successful testing of an upgraded imaging system capable of capturing high-quality images of shockwaves, rapid pressure changes which are produced when an aircraft flies faster than the speed of sound, or supersonic. Shockwaves produced by aircraft merge together as they travel through the atmosphere and are responsible for what is heard on the ground as a sonic boom.
The system will be used to capture data crucial to confirming the design of the agency’s X-59 Quiet SuperSonic Technology X-plane, or X-59 QueSST, which will fly supersonic, but will produce shockwaves in such a way that, instead of a loud sonic boom, only a quiet rumble may be heard. The ability to fly supersonic without a sonic boom may one day result in lifting current restrictions on supersonic flight over land.
The images feature a pair of T-38s from the U.S. Air Force Test Pilot School at Edwards Air Force Base, flying in formation at supersonic speeds. The T-38s are flying approximately 30 feet away from each other, with the trailing aircraft flying about 10 feet lower than the leading T-38. With exceptional clarity, the flow of the shock waves from both aircraft is seen, and for the first time, the interaction of the shocks can be seen in flight.
“We’re looking at a supersonic flow, which is why we’re getting these shockwaves,” said Neal Smith, a research engineer with AerospaceComputing Inc. at NASA Ames’ fluid mechanics laboratory.
When aircraft fly faster than the speed of sound, shockwaves travel away from the vehicle, and are heard on the ground as a sonic boom. NASA researchers use this imagery to study these shockwaves as part of the effort to make sonic booms quieter, which may open the future to possible supersonic flight over land. The updated camera system used in the AirBOS flight series enabled the supersonic T-38 to be photographed from much closer, approximately 2,000 feet away, resulting in a much clearer image compared to previous flight series.
“What’s interesting is, if you look at the rear T-38, you see these shocks kind of interact in a curve,” he said. “This is because the trailing T-38 is flying in the wake of the leading aircraft, so the shocks are going to be shaped differently. This data is really going to help us advance our understanding of how these shocks interact.”
The study of how shockwaves interact with each other, as well as with the exhaust plume of an aircraft, has been a topic of interest among researchers. Previous, subscale schlieren research in Ames’ wind tunnel, revealed distortion of the shocks, leading to further efforts to expand this research to full-scale flight testing.
While the acquisition of these images for research marked one of the goals of AirBOS, one of the primary objectives was to flight test advanced equipment capable of high quality air-to-air schlieren imagery, to have ready for X-59’s Low-Boom Flight Demonstration, a mission that will use the X-59 to provide regulators with statistically valid data needed for potential regulation changes to enable quiet commercial supersonic flight over land.
“We’re seeing a level of physical detail here that I don’t think anybody has ever seen before,” said Dan Banks, senior research engineer at NASA Armstrong. “Just looking at the data for the first time, I think things worked out better than we’d imagined. This is a very big step.”
The X-59 Quiet SuperSonic Technology X-plane, or QueSST, will test its quiet supersonic technologies by flying over communities in the United States. X-59 is designed so that when flying supersonic, people on the ground will hear nothing more than a quiet sonic thump – if anything at all. The scientifically valid data gathered from these community overflights will be presented to U.S. and international regulators, who will use the information to help them come up with rules based on noise levels that enable new commercial markets for supersonic flight over land.
Additional images included a “knife-edge” shot of a single T-38 in supersonic flight, as well as a slow-speed T-34 aircraft, to test the feasibility of visualizing an aircraft’s wing and flap vortices using the AirBOS system.
The images were captured from a NASA B-200 King Air, using an upgraded camera system to increase image quality. The upgraded system included the addition of a camera able to capture data with a wider field of view. This improved spatial awareness allowed for more accurate positioning of the aircraft. The system also included a memory upgrade for the cameras, permitting researchers to increase the frame rate to 1400 frames per second, making it easier to capture a larger number of samples. Finally, the system received an upgraded connection to data storage computers, which allowed for a much higher rate of data download. This also contributed to the team being able to capture more data per pass, boosting the quality of the images.
In addition to a recent avionics upgrade for the King Air, which improved the ability of the aircraft to be in the exact right place at the exact right time, the team also developed a new installation system for the cameras, drastically reducing the time it took to integrate them with the aircraft.
“With previous iterations of AirBOS, it took up to a week or more to integrate the camera system onto the aircraft and get it working. This time we were able to get it in and functioning within a day,” said Tiffany Titus, flight operations engineer. “That’s time the research team can use to go out and fly, and get that data.”
While the updated camera system and avionics upgrade on the B-200 greatly improved the ability to conduct these flights more efficiently than in previous series, obtaining the images still required a great deal of skill and coordination from engineers, mission controllers, and pilots from both NASA and Edwards’ U.S. Air Force Test Pilot School.
Using the schlieren photography technique, NASA was able to capture the first air-to-air images of the interaction of shockwaves from two supersonic aircraft flying in formation. These two U.S. Air Force Test Pilot School T-38 aircraft are flying in formation, approximately 30 feet apart, at supersonic speeds, or faster than the speed of sound, producing shockwaves that are typically heard on the ground as a sonic boom. The images, originally monochromatic and shown here as colorized composite images, were captured during a supersonic flight series flown, in part, to better understand how shocks interact with aircraft plumes, as well as with each other.
In order to capture these images, the King Air, flying a pattern around 30,000 feet, had to arrive in a precise position as the pair of T-38s passed at supersonic speeds approximately 2,000 feet below. Meanwhile, the cameras, able to record for a total of three seconds, had to begin recording at the exact moment the supersonic T-38s came into frame.
“The biggest challenge was trying to get the timing correct to make sure we could get these images,” said Heather Maliska, AirBOS sub-project manager. “I’m absolutely happy with how the team was able to pull this off. Our operations team has done this type of maneuver before. They know how to get the maneuver lined up, and our NASA pilots and the Air Force pilots did a great job being where they needed to be.”
“They were rock stars.”
The data from the AirBOS flights will continue to undergo analysis, helping NASA refine the techniques for these tests to improve data further, with future flights potentially taking place at higher altitudes. These efforts will help advance knowledge of the characteristics of shockwaves as NASA progresses toward quiet supersonic research flights with the X-59, and closer toward a major milestone in aviation.
The 1st Expeditionary Civil Engineer Group provides theater-wide engineering technical services, light and heavy troop labor construction and repairs within the U.S. Central Command area of responsibility in order to engineer combat power and establish and sustain combat platforms for USCENTCOM and other joint forces.
Within the 1st CEG are the 577th Expeditionary Prime Base Engineer Emergency Force, or PRIME BEEF, and the 557th Expeditionary Rapid Engineer Deployable Heavy Operational Repair Squadron, or REDHORSE, both sister tenants consisting of two separate construction teams with separate projects at Al Dhafra Air Base, United Arab Emirates.
REDHORSE is a self-sustaining, mobile, heavy construction squadron, capable of rapid response and independent operations in remote, high-threat environments worldwide.
“We have teams all over the AOR building anything from taxiways on airfields to entire logistics support areas, to digging wells to provide water for bases in austere locations,” said Capt. Jared Erickson, 557th ERHS Al Dhafra AB site officer in charge.

“My team here on (Al Dhafra AB) is almost like a miniature mission support group,” added Erickson. “We have highly-skilled vehicle maintainers that keep our heavy equipment fleet running strong and a supply team that can acquire construction materials from around the world. We are a self-sustaining construction team that can build almost anything, anywhere.”
Two of the current projects the 557th ERHS are working on are a warehouse for airfield damage repair equipment and a new Patriot Missile site.
“We are building a 13,000-square-foot warehouse to store and protect (.7 million) worth of airfield damage repair equipment,” said Erickson. “Additionally, we are in the process of finalizing the new Patriot Missile site, including 15 different projects valued at (.8 million) for roads, launcher pads, sunshades, tents and an electrical distribution system.”

The 577th Expeditionary PRIME BEEF Squadron provides a full range of engineering support required to establish, operate, and maintain garrison and contingency air bases.
Prime-BEEF forces maintain the necessary equipment and personnel to support fire emergency services; expedient construction; explosive incident response; emergency management; chemical, biological, radiological and nuclear response and many other specialized mission duties.
“The 577th EPBS is composed of Civil Engineering Air Force Specialty Codes, but have a separate role from base CE as we perform major construction and repair projects for (U.S. Air Forces Central Command),” said Capt. Paige Blackburn, 577 EPBS OIC of troop construction.
Currently, they are constructing a site by building an 18-foot tall mound and foundation to support a tower.
“The foundation system is made entirely from concrete and the site will have several miles of reinforcing steel rebar,” said Blackburn. “The tower and equipment weighs more than 120,000 pounds and is attached by large anchor bolts cast into the concrete piers. The tolerance of anchor bolt placement is extremely critical to ensure the tower frame will fit perfectly.”

Projects such as this can be challenging and require the use of different techniques and skillsets to complete the task.
“Setting the anchor bolts perfectly was incredibly challenging,” added Blackburn. “To set this accurately required age-old techniques of steel tape, construction squares, basic trigonometry, true ingenuity and nearly all the ladders on base. Thankfully, we have Master Sgt. James Morgan, a Heavy and Construction Equipment expert Guardsman with 30 years of construction experience. The project involves a 15-person construction team.”
Other completed projects include a 320-room renovation totaling 0,000, a id=”listicle-2625336716″.4 million renovation of the Oasis Dining Facility, and several waterline, sewer line, and communication duct bank construction projects.
“(1st) ECEG is the preferred choice for projects that require a rapid construction completion date, and is also the safer option for construction that intertwines with sensitive and valuable information,” said Blackburn.
With the REDHORSE and Prime BEEF Squadrons providing their expertise throughout Al Dhafra AB, the base continues to improve for the next rotation of deployers and continuation of the mission.
The Coast Guard‘s top officer said on Aug. 1, 2018, that the U.S. can’t afford to delay its presence in the Arctic. But lawmakers are eyeing the cash planned for a new icebreaker to fund the wall on the U.S.-Mexico border.
With the November 2018 primaries looming, some members of Congress are eager to show their constituents that they support President Donald Trump’s plans to build a wall along sections of the southwestern border. That left $750 million for a new heavy polar icebreaker out of a draft of the Department of Homeland Security Appropriations Act.
“I’m going to take a guardedly optimistic approach that … there’s still a lot of interest in getting an icebreaker to replace our 40-plus-year-old Polar Star, which is the only heavy icebreaker in the U.S. arsenal,” Coast Guard Commandant Adm. Karl Schultz said at an event hosted by the Center for Strategic and International Studies. “… We need that ship now.”
A report released July 27, 2018, by the Congressional Research Service warns that Russia is increasing its military presence in the Arctic region. The Russians have more than 45 icebreakers, and they’re currently working on building a nuclear version, Schultz said.
China has also declared itself a near-Arctic nation and is working on building a new icebreaker. Diminishing ice levels could lead to an influx of traffic in the Arctic in coming years, and there’s “increasing mission demand for the Coast Guard up there,” Schultz said.

That’s as two of the Coast Guard’s three polar icebreakers — Polar Star and Polar Sea — have exceeded their 30-year services lives, the report states. The Polar Sea is no longer operational, and the need for search-and-rescue and other missions in the region will increase as traffic in the Arctic picks up.
“The reality of the Arctic is on us today,” Schultz said. “My thinking is a six-three-one strategy. We need six icebreakers — three of them need to be heavy icebreakers and we need one today. We need to get going there.”
He said Trump’s 2019 budget request, which includes plans for a new icebreaker, shows that the Coast Guard’s mission in the region is a priority for this administration. The Senate’s appropriations draft for DHS still includes the 0 million for a Coast Guard icebreaker, so it’s still possible that the service could get the funding in 2019.
Eight House Democrats sent a letter to Rep. Rodney Frelinghuysen, chairman of the House Appropriations Committee, and Rep. Kevin Yoder, Homeland Security subcommittee chairman, criticizing the plan to ditch the 0 million icebreaker funding request,Business Insider reported.
The bill wastes “a staggering .9 billion on a border wall and increasing the Immigration and Customs Enforcement budget by 8 million,” the letter states, while leaving U.S. national security at a disadvantage for years to come.
The Coast Guard is working with the Navy on plans to acquire three heavy icebreakers for about 0 million per ship.

After the horrific terror attacks at the 1972 Munich Summer Olympics ended in the death of 11 hostages, nations of the world began creating their own versions what we, in the United States, call Special Weapons and Tactics teams, or SWAT teams. Just under a year later, France established their very own elite tactical police unit called the Groupe d’Intervention de la Gendarmerie Nationale, or GIGN.
Their counter-terrorism efforts are well regarded when they operate within their homeland, but not many know that they’re also a component of the French Armed Forces, which means they’re one part elite police officers and one part special operations soldier.
They’ve quickly become the most experienced and successful counter-terrorist organization in the world, tallying up over 1,800 publicly known missions with a near-flawless track record. And each time the Gendarmerie step up against a threat, they’ll always bring a trusty six-shooter revolver as their sidearm.
If it looks stupid, but works, it ain’t stupid.
(Groupe d’Intervention de la Gendarmerie Nationale)
While the GIGN does employ a wide variety of firearms for any given mission, including the MP5 submachine gun, the Fabarm SDASS Tactical shotgun, the Hécate II sniper rifle, and, recently, the BREN 2 rifle, their sidearm of choice is almost always the Manurhin MR73 double-action revolver. It should be noted that some have been known to carry Glock 17s, but that’s more the exception than the rule.
When the testing which sidearm to field, the MR73 made the cut after the teams were able to each shoot over 150 rounds of .38 Special with their sample weapons. They didn’t need to see any other firearms — the MR73 was the first and only sidearm they wanted to test.
Each MR73 is made to be used in marksmanship competitions. Each has an adjustable trigger weight in both double-action and single-action modes so it can be made to perfectly fit its wielder.
Even when the officer is given a choice of firearms, they’ll still almost always take the revolver. Because nothing beats a classic.
(Groupe d’Intervention de la Gendarmerie Nationale)
But while the MR73 revolver is a solid, practical choice, it’s just as much a status symbol. Commissioner Robert Broussard also saw what the revolver meant to the lawmen of America. It was the weapon of choice used by police to take down both Wild West outlaws and prohibition-era gangsters. A weapon like that earned its place among his police.
Historical status aside, the Manurhin MR73 is one the last remaining high-quality French firearms. The truth is, there simply aren’t many French firearm manufacturers that strive to achieve ultimate quality. Having a highly-customizable, expertly-crafted, .38 Special-firing symbol of both France industry and Wild West lawman? It’s the perfect match for the GIGN.
For seven decades, the NATO alliance has practiced collective defense and deterrence against evolving international threats, and over the years, its capabilities have changed accordingly.
NATO’s most “powerful weapon,” according to Jim Townsend with the Center for a New American Security, is the “unity of the alliance,” but the individual allies also possess hard-hitting capabilities that could be called upon were it to face high-level aggression.
Heather Conley with the Center for Strategic and International Studies believes that Russia is likely to continue to press the alliance through low-end influence and cyberwarfare operations. Still, she explained to Business Insider, NATO needs to be seriously contemplating a high-end fight as Russia modernizes, pursuing hypersonic cruise missiles and other new systems.
So, what does that fight look like?
“I’ve always likened it to a potluck dinner,” Townsend told Business Insider. “If NATO has this potluck dinner, what are the kinds of meals, kind of dishes that allies could bring that would be most appreciated?”
“If a host is looking to invite someone who is going to bring the good stuff, they are for sure going to invite the United States,” he explained, adding that “in all categories, the US leads.”
Nonetheless, the different dinner guests bring a variety of capabilities to the table. Here’s some highlights of the many powerful weapons NATO could bring to bear against Russia.

1. F-35 Lightning II Joint Strike Fighter
“The air side of the NATO equation is led by the United States with the F-35 and other various aircraft,” Townsend told BI.
The fifth-generation F-35 Joint Strike Fighter is an aircraft that rival powers have been unable to match its stealth and advanced suite of powerful sensors.
While some NATO countries are looking at the F-35 as a leap in combat capability, others continue to rely on the F-16, an older supersonic fighter that can dogfight and also bomb ground targets. And then some countries, like Germany, are considering European alternatives.

2. Eurofighter Typhoons
The Eurofighter Typhoon is a capable mutli-role aircraft designed by a handful of NATO countries, namely the UK, Germany, Italy, and Spain, determined to field an elite air-superiority fighter. France, which walked away from the Eurofighter project, independently built a similar fighter known as the Dassault Rafale.
Observers argue that the Typhoon is comparable to late-generation Russian Flanker variants, such as the Su-35.
While each aircraft has its advantages, be it the agility of the Typhoon or the low-speed handling of the Flanker, the two aircraft are quite similar, suggesting, as The National Interest explained, that the Eurofighter could hold its own in a dogfight with the deadly Russian fighter.

The US provides conventional and nuclear deterrence capabilities through the regular rotation of bomber aircraft into the European area of operations.
American bombers have been routinely rotating into the area since Russia annexed Crimea in 2014, according to Military.com. That year, the Pentagon sent two B-2 Spirit bombers and three B-52s to Europe for training. The B-1B Lancers are also among the US bombers that regularly operate alongside NATO allies.

“There’s also the maritime posture, particularly as Russia continues to rely on a submarine nuclear deterrent. We need a stronger presence. That’s why we’re seeing Norway, the US, UK do more with the P-8As,” Conley, the CSIS expert, told BI.
Facing emerging threats in the undersea domain, where the margins to victory are said to be razor thin, NATO allies are increasingly boosting their ability to hunt and track enemy submarines from above and below the water.
While there are a number of options available for this task, the US Navy P-8A Poseidon patrol plane, which was brought into replace the US military’s older P-3 Orions, are among the best submarine hunters out there.

Another effective anti-submarine capability is that provided by the various frigates operated by a number of NATO countries.
“The NATO allies, in particular Italy, France, Spain, all have frigates that have very capable anti-submarine warfare systems,” Bryan Clark with the Center for Strategic and Budgetary Assessments told BI.
“They have active low-frequency sonars that are variable-depth sonars. They can find submarines easily, and they are very good against diesel submarines.” These forces could be used to target Russian submarines in the Eastern Mediterranean and into the Black Sea.
“Norway and Denmark also have really good frigates,” he explained. “They could go out and do anti-submarine warfare” in the North Sea/Baltic Sea area, “and they are very good at that.”

The Apache gunship helicopter, capable of close air support, has the ability to rain down devastation on an approaching armor column.
The attack helicopters can carry up to sixteen Hellfire missiles at a time, with each missile possessing the ability to cripple an enemy armor unit. The Hellfire is expected to eventually be replaced with the more capable Joint Air-to-Ground Missile.
The Cold War-era Apache attack helicopters have been playing a role in the counterinsurgency fight in the Middle East, but the gunships could still hit hard in a high-end conflict.
7. German Leopard 2
The Leopard 2 main battle tank, which gained a reputation for being “indestructible,” is a formidable weapon first built to blunt the spearhead of a Soviet armor thrust and one that would probably be on the front lines were the NATO alliance and Russia to come to blows.
While this tank, a key component of NATO’s armored forces, took an unexpected beating in the fight against the Islamic State in Syria, it is still considered one of the alliance’s top tanks, on par with the US M1 Abrams and the British Challenger 2.
Observers suspect that the Leopard 2, like its US and British counterparts, would be easily able to destroy most Russian tanks, as these tanks are likely to get the jump on a Russian tank in a shoot out.

8. US Nimitz-class aircraft carriers
A last-minute addition to last year’s Trident Juncture exercise — massive NATO war games designed to simulate a large-scale conflict with Russia — was the USS Harry S. Truman, a Nimitz-class aircraft carrier, and its accompanying strike group.
The carrier brought 6,000 servicemembers and a large carrier air wing of F/A-18 Super Hornets to Norway for the largest drill in years.
“One thing the NATO naval partners have been looking at is using carriers as part of the initial response,” Clark told BI. The US sails carriers into the North Atlantic to demonstrate to Russia that the US can send carriers into this area, from which it could carry out “operations into the Baltics without too much trouble,” he added.
America’s ability to project power through the deployment of aircraft carriers is unmatched, due mainly to the massive size, sophistication and training regimen of its carrier fleet. The UK and France also have aircraft carriers.

9. PATRIOT surface-to-air missile system
PATRIOT, which stands for “Phased Array Tracking Radar to Intercept on Target,” is an effective surface-to-air guided air and missile defense system that is currently used around the world, including in a number NATO countries.
There is a “need for an integrated air and missile defense picture,” Conley told BI. “That is certainly a high-valued protection for the alliance.”
NATO is also in the process of fielding Aegis Ashore sites, land-based variants of the sea-based Aegis Ballistic Missile Defense System, that can track and fire missiles that intercept ballistic targets over Europe.

10. US Virginia-class submarines
Virginia-class submarines, nuclear-powered fast attack boats, are among the deadliest submarines in the world. They are armed with torpedoes to sink enemy submarines and surface combatants, and they can also target enemy bases and missile batteries ashore with Tomahawk cruise missiles.
These submarines “could be really useful to do cruise missile attacks against some of the Russian air defense systems in the western military district that reach over the Baltic countries,” Clark told BI.
“You can really conduct air operations above these countries without being threatened by these air defense systems. So, you would want to use cruise missiles to attack them from submarines at sea.”
