A group of 177 cybersecurity experts have signed a joint open letter calling on the UK government voicing concerns about the NHS’ plan to roll out a contact tracing app designed to tell people when they’ve come into contact with suspected coronavirus patients.
NHSX, the NHS’ digital experimental arm, says the app will be rolled out in Britain in the next two to three weeks. The way it works is when people sign up to the app, their phone sends out Bluetooth signals to determine what other phones are in its vicinity. If a user develops symptoms they’ll be able to report themselves in the app, and their phone will then send out an alert to all the phones it’s been nearby over the previous two weeks.
The UK has taken the decision to eschew the contact tracing API being built by Apple and Google for use by governments. This decision is partly down to the fact that the UK has decided it wants to centralize users’ data on an external server, making it easier to analyze, rather than keeping processing limited to people’s devices. Apple and Google’s API stipulates that apps use the decentralized method, which is more privacy-conscious.
“It has been reported that NHSX is discussing an approach which records centrally the de-anonymized ID of someone who is infected and also the IDs of all those with whom the infected person has been in contact,” the joint letter reads. The experts argue that this data hoard could facilitate “mission creep,” i.e. the government could later use the data for purposes other than tracking COVID-19.
“It is vital that, when we come out of the current crisis, we have not created a tool that enables data collection on the population, or on targeted sections of society, for surveillance.”
They noted that “invasive information” about users could be exploited.
“Such invasive information can include the ‘social graph’ of who someone has physically met over a period of time. With access to the social graph, a bad actor (state, private sector, or hacker) could spy on citizens’ real-world activities. We are particularly unnerved by a declaration that such a social graph is indeed aimed for by NHSX,” the experts write.
The experts ask in their letter that NHSX minimize the data it extracts from users to build trust in the app so it can be effectively deployed. Experts say 80% of smartphone users the UK would need to install the app for it to be effective in combatting the spread of coronavirus, and privacy concerns could mean falling short of that percentage.
They also ask that NHSX not build databases that could de-anonymize users, and that they lay out how the app will be phased out after the coronavirus crisis subsides.
When The Hunt for Red October came out in 1984, and with it the invention of the techno-thriller genre (author Tom Clancy’s claim to literary greatness), one of the stars was a modified Typhoon-class nuclear-powered ballistic missile submarine (SSBN). That novel, of course, was adapted to film in 1990.
The book and the film featured two different versions of the silent drive. The book used impellors, while the film used magneto-hydrodynamic propulsion. Now, something that is somewhat similar to the latter version of the Red October’s silent drive could be a reality… thanks to the People’s Liberation Army Navy.
Permanent magnet motors run much more quietly than conventional types currently in use on submarines. This is due to their “brushless” nature, which also means they can be smaller, taking up less volume on submarines (which are notoriously cramped) and increasing their reliability and also improving their endurance.
According to GlobalSecurity.org, China has a small number of nuclear submarines at present, roughly a half-dozen attack subs and four ballistic missile submarines. While greatly outnumbered by those of the United States, China is planning to build many more nuclear-powered subs by 2030, including versions more modern than the Shang and Jin classes that are their current state of the art.
The United States is not standing still. Reportedly, the new Columbia-class SSBNs will also be using a magnetic-drive technology. That said, it should be noted that in both the book and movie versions of Hunt for Red October, the United States Navy was able to track the titular submarine.
The AH-1Z aircraft is an updated version of the AH-1W, bringing new capabilities and features into the squadron’s arsenal.
“The AH-1Z’s are replacing the AH-1W’s, which are essentially from the 1980’s,”said Marine Corps Capt. Julian Tucker, the squadron’s ground training officer. “Some big takeaways on the new aircraft can be summarized into greater fuel capacity, ordnance capabilities, and situational awareness.”
The AH-1Z can carry and deploy 16 Hellfire missiles, effectively doubling the capacity of its predecessor, the AH-1W. Updated avionics systems and sensors are another important aspect of the upgrade. The upgraded capabilities allow the squadron and Marine Corps Base Hawaii to further project power and reach in the Asia-Pacific region.
“With the new turret sight system sensor, we can see threats from much further out than before,” Tucker said. “Obviously, that’s a huge advance for our situational awareness.”
Marine Corps Maj. Christopher Myette, the assistant operations officer for the squadron, piloted one of the new Vipers back from Joint Base Pearl Harbor-Hickam.
“Having the displays under glass is a big change from the old steam gauges,” Myette noted on the new digital display systems. “Another thing you notice is that in the electrical optical sensor, there’s a night and day difference.”
The updated electrical systems create a new situation for Marines like Sgt. Jeremy Ortega, an avionics technician with the squadron.
“The new Zulus incorporate systems from the AH-1W and the UH-1Y and essentially combine them,” Ortega said. “The upgraded turret sight systems create much more in-depth images, which allow pilots to pinpoint targets better and get more descriptive, accurate pictures.”
Marines like Ortega are essential to keep the squadron at the peak of readiness during the transition, Myette said.
“Maintenance Marines have done an outstanding job of accepting the new aircraft,” Myette said. “They have really done the majority of the heavy lifting on this project, and we definitely appreciate them.”
Although there will be a learning curve working with the new system due to its modernity, Ortega said he is excited to work with the upgraded helicopters.
“Times are changing and things are evolving,” Ortega said. “It’s time for the AH-1W’s to go to bed. And, the AH-1Z’s are the perfect candidate to replace them.”
It’s the kind of video that puts a lump in your throat.
But it’s also a crystal clear demonstration of the training that teaches Naval aviators to keep their cool.
In this incredible clip from the USS Eisenhower, a Navy E-2C Hawkeye surveillance plane coasts into what seems like a textbook landing during a calm day at sea off the coast of Virginia.
As the Hawkeye traps the number four wire, it seems as if the plane made a good arrest. But while the twin turboprop airplane strains to a stop, the cable suddenly snaps, sending sailors on the flight deck scrambling and the plane plunging off the end of the flight deck. It takes a heart-stopping 6 seconds for the plane to pull out of the dive and into view above the line of the flight deck.
According to the Virginian Pilot newspaper which obtained the investigation report into the March 18 incident, the arresting gear was misprogrammed for the Hawkeye’s landing, causing the cable to snap. While the aircrew landed the plane safely ashore, eight sailors were injured on the flight deck.
The US and its coalition partners have dropped more bombs on Afghanistan in the first ten months of 2018 than any year in the past five years, the US military revealed Nov. 29, 2018.
Between January and October of 2018, the US-led coalition dropped 5,982 bombs in support of Operation Freedom Sentinel and Operation Resolute Support, significantly more than the previous years.
Coalition strike aircraft flew 6,584 sorties during that time, 783 of which involved the release of a weapon, the US Air Forces Central Command’s Combined Air Operations Center disclosed in its monthly Airpower Statistics report.
The Trump administration made airpower a priority for the war in Afghanistan. With the relocation of Air National Guard KC-135 refueling tankers from Al Udeid Air Base in Qatar to Kandahar last fall, the US-led coalition has been able to increase the number of airstrikes against the Taliban and other enemy combatants.
In addition to the refueling tankers, a number of A-10C Thunderbolt attack aircraft, HH-60G Pave Hawk helicopters, and MQ-9 Reaper drones were also shifted to Kandahar, Military.com reported Nov. 28, 2018.

The US and its coalition partners have made progress in the fight against ISIS, but while the number of bombs falling on Afghanistan is on the rise, the coalition continues to struggle to secure victory against a surging and brutal Taliban foe.
The Afghan government’s control of the country has been slipping over the past few years, falling from 72 percent in 2015 to just over half in the third quarter of 2018. In that period, Afghanistan lost 28,529 security force personnel, the Afghan president said in November 2018.
The US continues to suffer losses as well.
Five US troops were killed in November 2018, one to an insider attack, one to accidental friendly fire, and three to an improvised explosive device. Thirteen US service members have died fighting in Afghanistan in 2018, as US forces have largely shifted to advise, assist and training missions.
The Taliban “are not losing right now, I think that is fair to say,” Gen. Joseph Dunford, chairman of the Joint Chiefs of Staff, said. “We used the term stalemate a year ago and, relatively speaking, it has not changed much.”

“We do believe the Taliban know that at some point they do have to reconcile,” Dunford added, stressing that the key is to pressure the Taliban, which has also suffered heavy losses, to eventually negotiate.
Reporters from the Washington Post recently questioned President Donald Trump on America’s presence in Afghanistan. “We’re there because virtually every expert that I have and speak to say if we don’t go there, they’re going to be fighting over here. And I’ve heard it over and over again,” he replied.
He further remarked that there is talk of peace, but added that he was unsure if that is a real possibility.
Speaking to reporters at the Pentagon Nov. 28, 2018, Mattis said the peace process is “picking up momentum,” but did not go into additional detail.

The U.S. Air Force announced plans to ramp up its pilot training to produce 1,500 pilots a year by fiscal 2022. Now, Air Education and Training Command (AETC) has divulged preliminary blueprints on how it anticipates accomplishing the task.
Air Force Secretary Heather Wilson said before a Senate Armed Services readiness and management support subcommittee hearing Oct. 10, 2018, that the service will increase its current 1,160 pilot training slots to 1,311 in fiscal 2019, aiming for 1,500 every year shortly thereafter.
“AETC has been tasked to produce about 1,500 pilots per year … That number includes active-duty Air Force, Air Force Reserves, Air National Guard and international students,” command spokeswoman Marilyn Holliday told Military.com this in October 2018.
While the undertaking is in its initial stages, the command will use programs such as the experimental Pilot Training Next — paired with Pilot Instructor Training Next — to improve how teachers and incoming students work together.

AETC is also updating its Undergraduate Pilot Training (UPT) curriculum to streamline how quickly the Air Force can produce new pilots, Holliday said.
“The final touches to the new Undergraduate Pilot Training syllabi were adjudicated and are now in the initial stages of execution,” she said.
Revising pilot training
The curriculum’s redesign gives squadron commanders the ability to refine training to better meet the needs of individual students, AETC said in a recent release.
Previously, students went back and forth between simulators and the flight line. The new syllabus moves “11 simulators that had been previously spread out over a three- to four-month time frame, into a single block of training prior to the first flight in the aircraft,” Holliday said.
It’s also a blended learning model, she said, that incorporates several best practices from “advanced military flight training and civilian flight training.”
Students will cut their training time from 54 to 49 weeks once the changes are fully implemented.
“We are still in the early phase of executing the syllabus redesign, but initial performance from students indicates increased pilot performance,” Holliday said.
Students will advance at their own pace. Previously, they had to wait until the entire class completed stages or assignments before moving on to the next. AETC will now allow for individual students to complete courses faster or slower as needed, officials said.
Holliday said this will not alter the official course length, but the time a given student spends in the course could change. The first UPT students to use the adjusted curriculum will graduate in spring 2019, she said.
Pilot Training Next
Thirteen students graduated from the first, experimental Pilot Training Next (PTN) class in August 2018 after six months of learning to fly in virtual-reality simulators. The program ran 24 weeks and “included 184 academic hours, with approximately 70 to 80 flight hours in the T-6 Texan II, as well as approximately 80 to 90 hours of formal flight training in the simulator,” Holliday said. Students also trained on their own time in the simulators.
“We want to learn as fast as possible,” said 2nd Lt. Christofer Ahn, a student pilot, in an interview before graduating. “Being able to use the simulators is a huge step in allowing us to accelerate through our training.”

The service recently announced there will be a second class to test Pilot Training Next before the results are briefed to Wilson and Chief of Staff Gen. David Goldfein, who will decide whether the program will be incorporated into formal pilot training. The second class will begin training in January 2019.
Holliday said that lessons learned from PTN have already been incorporated into traditional Undergraduate Pilot Training, as well as Pilot Instructor Training.
Instructors are also refining the ways they connect with students through innovation and simulation training. With a program called Pilot Instructor Next, they are looking for ways to develop what AETC calls the “Mach-21” airman, or the next generation of 21st century pilots.
Lt. Gen. Steven Kwast, the AETC commander, coined the term to describe what the Air Force wants in its new pilots.
“A Mach-21 Air Force essentially is comprised of airmen who learn faster, adapt faster and strategically out-think the enemy, because they are moving at Mach-21 speed,” he said.
To produce such high-quality and sought-after pilots, instructors need to up their game.
“Through Pilot Instructor Training Next, AETC flying squadrons have been equipped with virtual-reality simulators and 360-degree video headsets to integrate into syllabi,” Holliday said. “Since implemented, there have been measurable benefits from the addition of technology, and 10 instructor pilots are slated to graduate from the PIT Next program each month.”

Its biggest advantage, AETC says, is the ability to test students in high-stress environments in the safe space of a simulator.
“Virtually, instructors can put students in any situation to determine if they would recognize the danger and whether or not they take the right course of action,” Holliday said. “Students also have the opportunity to take home mobile-video headsets, which connect to the pilot’s smartphone and allow for on-command and on-demand training, which has also been helpful.”
She added, “Incorporating this level of technology and deep-repetition learning allows these students to see the flight environment so many more times than they would have in the past.”
Aircrew Crisis Task Force
AETC is also coordinating with the Aircrew Crisis Task Force — set up in 2016 by the Pentagon — building on its “holistic plan to ensure the Air Force’s pilot requirements are met through retention of currently trained pilots as well as through the production pipeline.”
At the Oct. 10, 2018 hearing, Wilson said the Air Force is placing an emphasis on addressing the national aircrew shortage by focusing on pilot quality of service and quality-of-life issues.
The task force has looked at ways of giving fighter pilots and aircrew the ability to stay in rotations longer at select commands and bases in an effort to create stability for airmen affected by the service’s growing pilot shortage.
“We continue to work with the Aircrew Crisis Task Force to ensure our pilot production planning encompasses an airman from commissioning through training and then to their operational flying units,” Holliday said.

U.S. Army Reserve Lt. Col. Lisa Jaster was 37 years old when she attended Ranger School. While the average age of attendees in the course ranges in the early 20s, that didn’t deter her, and in October of 2015 she graduated from the course.
She was the first woman in the U.S. Army Reserve to do so.
Four years later, her advice to others is simple.
“You have to be ‘all-in,'” said Jaster. “Be willing to give everything you have for the school and maintain your integrity. The first week is published therefore you know what to expect and how to succeed. Once you’ve passed the physical entrance exam (RAP week), you will need to have the mental toughness to push through conditions that could beat a lesser person down.”
“Do not let ‘quit’ in,” she continued. “That means once you allow quitting into your mind as an option, it will move in, live there, steal your motivation, and eventually defeat you from within.”

The all-in attitude that Jaster says is the key to success for Ranger school has also been tantamount to accomplishments in other aspects of her life. As a citizen soldier, she demonstrates that one can serve their country while continuing to have a civilian career.
In the past three years, Jaster has been a senior project engineer with Shell Oil Co. before becoming the director of civil engineering for MS Engineering. She also has become a professional speaker with Leading Authorities, holding engagements across the country.
In the Army Reserve, she has been a battalion executive officer, an engineering team lead supporting the Iraqi Security Forces during Operation Inherent Resolve, and is now the brigade executive officer for the 420th Engineer Brigade, 416th Theater Engineer Command.
Throughout all of her experiences, her definition of leadership and what is expected of leaders has one constant: be consistent in your words and actions, and set the example for others to follow. This definition has served her well in both her military and civilian life.
“Everyone needs to be led as an individual, and each individual brings something to the fight as long as they are vested in the end state,” said Jaster. “A leader is someone who inspires those around them to be better versions of themselves.

“Traditionally,” she continued. “I have said that consistency is the most important aspect of leadership to ensure subordinates can perform in the absence of guidance,” After Ranger School, I have created the three Cs – Consistency, Communication and Competence. There are a lot of other aspects to being an effective leader, but these are necessary starting blocks.”
Jaster approaches her personal life with the same care as her professional one. A dual military couple, she and her husband, Marine Corps Lt. Col. Allan Jaster, have two children. Their support of each other and their children has been a critical factor in their accomplishments.
“Balancing the Citizen (employee, mom, wife, sister, daughter, and individual) with the soldier is very complicated,” said Jaster. “I used to try to silo both aspects of who I am but found that so much bleeds over from one job to the other that I need to be fluid with those lines.
“What that means,” continued Jaster. “Is that Army conference calls can happen during cheer practice, and I might need to review proposals for work while I am in the field with the Army. It means being open and honest with my spouse, my military boss, and my civilian supervisor about what I can handle and what might be coming up. Having a strong support team with regards to extended family, friends and hired help is critical to ensure nothing at home drops.”
Jaster does not want her Ranger School experience to define her. Since her completion of the course, she has advised to not identify soldiers and civilians by their race, sex or creed, but their skills, attributes and performance.
She created the hashtag #deletetheadjective for social media to emphasize her message, and throughout all of her speaking engagements, she has consistently stated the best teams are those with the highest level of competencies, not just a group identity. Being in the Army Reserve has allowed her to serve her country while creating awareness, and discussion, of the topic.

“Ranger school was just part of my path,” said Jaster. “It was not an end state. I have a larger public voice because of graduating from Ranger School. My true failure or success is what I decide to do with that voice. If I can live by the Ranger Creed and set an example which brings our community together for a smooth gender integration, then that is the goal I am striving for.”
Looking forward to the future, Jaster continues to strive for excellence. Whether in uniform or out, she has used her previous accomplishments to continue to fuel her drive to succeed and set the example for others to follow. Her discipline and dedication to her family, civilian profession, and military career is a standard she refuses to let falter.
“Ranger School does not make me a good or a bad officer,” said Jaster. “It does mean there are certain external expectations of me that were previously only self-imposed. This gives me an additional drive to continue to train martial arts, strength, endurance and tactics, even when time constraints make it difficult and my current job doesn’t require it.
“I am looking forward to being a battalion commander,” she continued. “After battalion command, I am not sure what the Army holds, but I plan to stay in uniform as long as I can.”
The International Court of Justice (ICJ) has confirmed that Iran has filed a lawsuit against the United States over the reimposition of sanctions against Tehran by U.S. President Donald Trump’s administration, claiming the move violates the nuclear treaty Tehran signed with the United States and five other world powers.
A U.S. State Department official, speaking to Reuters on condition of anonymity, said on July 17, 2018, that Iran’s application was “baseless” and that Washington intended “to vigorously defend the United States before the ICJ.”
Confirmation by the court on July 17, 2018, came a day after Iranian Foreign Minister Mohammad Javad Zarif said on Twitter that the case was filed at the ICJ to hold the United States “accountable for its unlawful reimposition of unilateral sanctions.”
“Iran is committed to the rule of law in the face of U.S. contempt for diplomacy and legal obligations,” Zarif tweeted. “It’s imperative to counter its habit of violating international law.”

Under the deal signed in 2015, the United States, Britain, France, Germany, Russia, China, and the European Union agreed to lift international sanctions against Iran.
In return, Iran scaled back its uranium-enrichment program and promised not work on developing nuclear weapons.
The lifting of sanctions has allowed Iran to sell its oil and natural gas on world markets — although secondary U.S. sanctions remained in place.
But in May 2018, the Trump administration unilaterally pulled the United States out of the Iran nuclear deal.
Trump said during a NATO summit in July 2018 that with the U.S. increasing sanctions on Iran, “at a certain point they’re going to call me and say, ‘Let’s make a deal,’ and we’ll make a deal.”
But Iranian Foreign Ministry spokesman Bahram Qasemi said on July 17, 2018, that if Trump wants to negotiate after pulling out of the international agreement, he would have to “initiate the call himself” because Iran’s top leadership was now rejecting any talks with the United States.
But these are not the first Americans to have been held hostage. A 2017 list from USA Today before Warmbier’s release noted some other incidents dating from 2009 to the present. These cases have involved civilians. However, prior to 1996, when Evan Hunziker swam across the Yalu River, there had been some incidents where American troops were held hostage.
The environmental research ship USS Pueblo (AGER 2) was attacked and captured by North Korean Forces. One American was killed in the initial attack, while 82 others were held for 11 months. The vessel is still in North Korean hands.

A CH-47 Chinook was shot down by North Korean forces, killing three of the crew. The surviving crewman was briefly held by the North Koreans until he was released, along with the bodies of the deceased.
Effective immediately, commands can now order the Improved Flame Resistant Variant (IFRV) coverall. Commander, U.S. Fleet Forces (USFF) announced manner and occasion of wear guidance for the IFRV Feb. 5 2018.
The approval of the IFRV as a fleet organizational clothing item to replace the legacy Flame Resistant Variant (FRV) coverall was announced in early January 2017 after the completion of a series of afloat wear tests. The IFRV addresses comfort and durability issues found with the original FRV coverall.
“The original FRV was rapidly introduced to the fleet because Sailor safety is our top priority,” said CAPT Mark Runstrom, director, Fleet Supply Operations/Services, USFF. “However, we recognized immediately that we needed a coverall that is more durable, functional, and comfortable as well as safe. That is what the IFRV is all about.”
Sailors stationed aboard ships and submarines will be issued a minimum of two IFRV coveralls with units authorized to procure name tags using unit operating target funds. The manner of wear will be the same as the FRV coveralls, prescribing wearers to don full sleeves and secured fastenings. The current 9-inch black, steel-toed boot and Navy or command ball caps are authorized for wear with the coverall.
Approved belts include a black cotton web belt for E1-E6, a khaki cotton web belt for chief petty officers and officers and; rigger’s belts are authorized at command discretion.
Rank tabs and insignia are authorized to be sewn or pinned on the coverall based on the wearer’s duties and unit preference.
Rectangular, Velcro-backed name tags will be worn centered, 1/4-inch above the left breast pocket-similar in size, shape, and content to the V-neck sweater name tag. Embossed leather name tags or fabric embroidered unit specific name tags similar to those worn on the green Nomex flight jacket will be authorized for wear at the discretion of unit commanders.
Blue or brown undershirts are authorized for wear with the IFRV, although blue undershirts are being phased out with the introduction of the Navy Working Uniform Type III.
Members will not be authorized to stencil or serialize any portion of outer fabric of the IFRV nor attach unit or flag patches due to the risk of degrading the flame resistant fabric. However, Sailors are allowed to stencil the inner parts for identification purposes.
The IFRV will be prescribed as an underway uniform and the appropriate attire for events such as sea and anchor detail. Commands can authorize the IFRV for wear ashore or in-port and when working in conditions where excessive wear to the uniform could occur or when needing arc or flash protection.
The IFRV coverall is made from a flame resistant, tri-fiber blend designed to offer arc flash protection and provide improved moisture management by allowing the fiber to breathe more efficiently. The IFRV coverall is also designed for sustained durability lasting nearly twice as long as the FRV.
Additionally, feedback during fleet testing of the IFRV revealed a desire for a two-piece FRV. USFF has developed several versions with varying design features that will be tested in the spring of 2018.
The men were calling in bomb after bomb — pinpointing al Qaeda positions in the hills and ridges of Tora Bora, miles from support and operating on their own for days.
In the end, the special operators from the Army’s elite Delta Force did all they could in the face of intense danger, feckless allies and brutal conditions to kill America’s public enemy number one. But to no avail.
The man who led those elite teams of Delta Force soldiers in the earliest days of the war in Afghanistan later wrote a book under the pen name Dalton Fury. Titled “Kill bin Laden: A Delta Commander’s Account of the Hunt for the World’s Most Wanted Man” it told in granular detail the risks this highly trained counterterrorism unit took to infiltrate the jagged mountains where Osama bin Laden was believed to be hiding and stitch together an ever-fraying patchwork of Afghan allies to help block his escape.
“We went into a hellish land that was considered impregnable and controlled by al Qaeda leaders who had helped defeat the Soviet Union,” Fury wrote. “We killed them by the dozen. Many more surrendered. … And we heard the demoralized — bin Laden speak on the radio, pleading for women and children to fight for him.”
“Then he abandoned them all and ran from the battlefield,” Fury added with some satisfaction. “Yes. He ran away.”
Fury was savaged by many in his former Delta and Special Forces community when the 2008 book was released, with many arguing he’d broken a code of silence on the secretive unit’s operations. His former colleagues outed his real name, Maj. Tom Greer, but he kept using Dalton Fury as his nomme de plume for a later series of popular fiction books about door kickers and contractors who hunted the world’s worst.
With the passage of time, the special ops community has settled down and Fury became Greer again. But despite his success in the world of fiction and his survival of many dangerous missions in Iraq, Afghanistan and the former Yugoslavia, among others, Greer is now fighting a battle he may not win.
According to friends and other sources, Greer recently has been diagnosed with terminal Pancreatic Cancer. His supporters have established a Facebook page in hopes of helping his family in their time of need.
Greer is a true warrior and decorated combat veteran of the world’s most deadly counterterrorism unit, doubtless he’ll fight this battle with the same grit and tenacity he did against America’s most dangerous enemies.
The photograph in this post shows a U.S. Navy Lockheed Martin F-35C Lightning II of Air Test and Evaluation Squadron 23 (VX-23) “Salty Dogs” during a test flight. Released by the Naval Air Warfare Center Aircraft Division, the image was taken as the stealth aircraft, carrying external AIM-9X Sidewinder AAMs (Air-to-Air Missiles), flies transonic: indeed, what makes the shot particularly interesting are the schlieren shock waves that flight test photographers captured as the JSF transitioned from sub-sonic to supersonic.
Schlieren imagery is a modern version of a 150-year-old German photography technique, used to visualize supersonic flow phenomena: a clear understanding of the location and strength of shock waves is essential for determining aerodynamic performance of aircraft flying at supersonic speed in different configurations, for improving performance as well as designing future jets.
“Schlieren imaging reveals shock waves due to air density gradient and the accompanying change in refractive index,” says the NASA website that published an extensive article about this particular kind of photography few years ago. “This typically requires the use of fairly complex optics and a bright light source, and until recently most of the available schlieren imagery of airplanes was obtained from scale model testing in wind tunnels. Acquiring schlieren images of an aircraft in flight is much more challenging. Ground-based systems, using the sun as a light source, have produced good results but because of the distances involved did not have the desired spatial resolution to resolve small-scale shock structures near the aircraft.”
This schlieren image of a VX-23 F-35C flying transonic shows the shock waves generated by the stealth aircraft.

Noteworthy, while schlieren imaging dramatically displays the shock wave of a supersonic jet (image processing software removes the background then combines multiple frames to produce a clear picture of the shock waves) change in refractive index caused by shock waves can also become visible when aircraft move at speed much lowen than transonic, as shown in photographs taken in 2018.
A T-38C passing in front of the sun at supersonic speed, generating shockwaves.
Here what I wrote last year about a crazy cool image of an F-35 flying through the famous Star Wars canyon taken by photographer Jim Mumaw:
At speed lower than the transonic region, air flows smoothly around the airframe; in the transonic region, airflow begins to reach the speed of sound in localized areas on the aircraft, including the upper surface of the wing and the fuselage: shock waves, generated by pressure gradient resulting from the formation of supersonic flow regions, represent the location where the air moving at supersonic speed transitions to subsonic. When the density of the air changes (in this case as a consequence of shock waves) there is a change in its refractive index, resulting in light distortion.
Generally speaking, shock waves are generated by the interaction of two bodies of gas at different pressure, with a shock wave propagating into the lower pressure gas and an expansion wave propagating into the higher pressure gas: while the pressure gradient is significant in the transonic region, an aircraft maneuvering at high-speed through the air also creates a pressure gradient that generates shock waves at speed much lower than the speed of sound.
