The Navy budget gives the service its long-sought-after F/A-18 Super Hornet increase by adding 14 fighters and more than $1 billion in procurement funds — all as part of a sweeping effort to increase the F-18 fleet size, meet mission requirements, accommodate new technologies, and ultimately fly alongside the F-35C through the 2040s.
Given the recent war-driven op-tempo involving global deployments and air strikes on ISIS, most of the F/A-18 E/F fleet, on average, has already consumed more half of its 6,000-flight hour expected service life. As a result, there has been a long-standing, multi-year Navy effort to acquire new F/A-18s in larger numbers to address urgent needs from combatant commanders.
When the F/A-18A and F/A-18C reach 8,000 flight hours, they are sent to the depot for service life extension upgrades with the hope of getting the airframes to 10,000 hours. However, many of the older aircraft are in need of substantial repairs and, in recent years, a large percentage of the Navy’s fleet of older Hornets have not been in service.
“Extension of legacy Hornet life requires additional inspections and deep maintenance that were not originally envisioned for the aircraft. Average repair time has significantly increased because of required engineering of unanticipated repairs, material lead times, and increased corrosion of airframes,” the Navy budget document writes.
As part of a specific effort to address this scenario, the Navy’s new budget request increases fund for civilian maintenance personnel hiring, depot-level maintenance work, and sustainment initiatives. The goal of this, according to Navy budget documents, is to “decrease the time to complete depot level maintenance caused by the number of high flight hours.”
Navy officials have told Warrior Maven that modifications include replacing the center barrel (section) and ensuring the airframe structures achieve 100% service life. Additional modifications increase the total landing limit and modifications to catapult attachment components can be incorporated to extend total catapults, service developers have described.
A carrier air wing consists of about 44 strike aircraft made up of two 10-aircraft squadrons and two 12-plane squadrons complemented by several electrical jamming aircraft.
The current composition of most carrier-based air wings includes 24 Super Hornets and 20 Hornets, however the Navy plans to replace some of its existing Hornets with F-35Cs. Although the budget does increase F-35C acquisition as well, the emergence of the carrier-launched stealth fighter will not remove combatant commanders need for the F-18.
The Navy had been planning for the Super Hornets to serve well into the 2030s, but now service leaders say that timeline will need to extend into the 2040s.
The Navy plans to acquire as many as 60 new F-35C aircraft over the next five years, according to the service budget request.
A U.S. Army artillery unit is pounding Islamic State fighters inside Syria from a remote desert camp just inside Iraq.
Soldiers from the 3rd Armored Cavalry Regiment artillery unit have been operating alongside Iraqi artillery units at a temporary fire support base in northwest Iraq near the Syrian border for the past several weeks, according to a recent Defense Department news release.
U.S. soldiers, Marines and sailors helped Iraqi forces build the camp by as part of Operation Inherent Resolve’s support of Operation Roundup, a major offensive by Syrian Democratic Forces aimed at clearing the middle Euphrates River Valley of entrenched, Islamic State of Iraq and Syria fighters.
Little has been made public in recent months about the U.S. military’s use of temporary fire bases to continue the ISIS fight. But NPR published a brief report July 2, 2018, about a “remote outpost” on the border of Iraq and Syria that seems to be the one described in the recent Defense Department release.
Some 150 Marines and soldiers are stationed there, NPR reported, in addition to Iraqi forces.
In the release, troops stationed at the fire base described the satisfaction of working side-by-side with Iraqi units.
“The most satisfying moment in the mission, so far, was when all three artillery units, two Iraqi and one U.S., executed simultaneous fires on a single target location,” said Maj. Kurt Cheeseman, Task Force Steel operations officer and ground force commander at the fire support base, in the release.
Language barriers forced U.S. and Iraqi artillery units to develop a common technical language to coordinate fire missions that involved both American and Iraqi artillery pieces.
“This mission required the use of multiple communications systems and the translation of fire commands, at the firing point, directing the Iraqi Army guns to prepare for the mission, load and report, and ultimately fire,” 1st Lt. Andrea Ortiz Chevres, Task Force Steel fire direction officer, said in the release.
The Iraqi howitzer unit used different procedures to calculate the firing data needed to determine the correct flight path to put rounds on target.
“In order to execute coalition fire missions, we had to develop a calculation process to translate their firing data into our mission data to validate fires prior to execution,” Cheeseman said in the release.
Sgt. 1st Class Isaac Hawthorne, Task Force Steel master gunner, added that Iraqi forces are “eager to work with the American M777 howitzer and fire direction crews and share artillery knowledge and procedures,” according to the release.
It’s not clear from the release when the base was created or how long it has been active. With little infrastructure and no permanent buildings, troops face temperatures above 100 degrees Fahrenheit in the desert.
“They are enduring harsh weather conditions and a lack of luxuries but, unlike previous deployments for many, each element is performing their core function in a combat environment,” Cheeseman said in the release. “The fire support base is a perfect example of joint and coalition execution that capitalizes on the strengths of each organization to deliver lethal fires, protect our force and sustain operations across an extended operational reach.”
Navy, Marine Corps and Air Force units provided planners, personnel and equipment to create the austere base, built on a bare patch of desert and raised by hand. Coalition partners from several different nations participated in the planning and coordination of the complex movement of supplies.
“Supplies were delivered from both air and ground by the Army, Air Force and Marines, and include delivery platforms such as medium tactical vehicles, UH-60 Black Hawks, CH-47 Chinooks, CV-22 Ospreys, C-130 Hercules and a C-17 Globemaster,” 1st Lt. Ashton Woodard, a troop executive officer in Task Force Longknife, said in the release. “We receive resupply air drops that include food, water, fuel, and general supplies.”
One of the most vital missions involved setting up a security perimeter to provide stand-off and protection for the U.S. and Iraqi artillery units.
“Following 10 days of around-the-clock labor in intense environmental conditions, the most satisfying moment was seeing the completion of the physical security perimeter,” said one Marine working security at the fire base, according to the release.

Hundreds of troops previously stationed in Texas and Arizona have been moved to California to support border patrol agents securing the border against the thousands of Central American migrants camped nearby.
“In coordination with CBP, it was determined that forces including military police, engineering and logistics units could be shifted from Texas and Arizona to support the CBP requirements in California,” US Northern Command told Business Insider, confirming an earlier report from The Washington Post.
“Approximately 300 service members have been repositioned to California over the past few days.”
In November 2018, there were 2,800 troops in Texas, 1,500 in Arizona, and another 1,500 in California. Over a period of several weeks, the active-duty military personnel deployed to these states ran over 60,000 feet of concertina (razor) wire.
Now, after the recent shift, there are 2,400 troops in Texas, 1,400 in Arizona, and 1,800 in California. The total number of active-duty troops at the border has decreased by about 200, dropping from 5,800 to 5,600, NORTHCOM explained to Business Insider, noting that changes are the result of mission assessments carried out in coordination with CBP.

While the number of troops deployed to the southern border has decreased, the number of troops serving in California is on the rise. Thousands of migrants have been pouring into Tijuana, which is where more than 5,000 migrants, possibly many more, are camped.
Border patrol agents clashed with hundreds of migrants Nov. 25, 2018, at San Ysidro, one of the largest and busiest ports of entry on the US-Mexico border, after what began as a peaceful protest meant to call attention to the plight of asylum seekers turned into a mad and chaotic dash.
Some migrants attempted to enter the US illegally by forcing their way through and over barricades while others threw rocks at US border agents after they overwhelmed Mexican authorities. The crowd of migrants was driven back by rubber pullets and tear gas.
More than one hundred migrants have been arrested by authorities in the US and Mexico. Many of those who have been detained face deportation, meaning that their weeks-long journey to the US will end where it began.
The role of US troops at the border has been in debate over the past few weeks, with critics of the president calling the deployment a waste of time, resources, and manpower.
While active-duty troops deployed to the border were initially limited to laying razor wire, the White House recently authorized US troops to use force, including lethal force if necessary, to defend CBP agents against violence.

A little over a month after the Helge Ingstad sank after colliding with a tanker in a Norwegian fjord, the Norwegian military has released footage from the submerged frigate.
The warship was rammed by a Malta-flagged tanker in the early morning hours of Nov. 8, 2018, in the port of Sture, north of Bergen, which is Norway’s second-largest city.
The frigate displaces 5,290 tons, and the tanker displaces over 62,500 tons when empty. But when the tanker is fully loaded, as it was at the time of the collision, that jumps to about 113,000 tons, more than an aircraft carrier. The collision tore a large hole in the starboard side of the frigate’s hull, which caused other compartments to flood.
Footage released by the Norwegian military, which you can see below, shows the damage sustained by the frigate.
A Norwegian rescue official said at the time of the collision that the frigate was “taking in more water than they can pump out. There is no control over the leak and the stern is heavily in the sea.”
According to a preliminary report released at the end of November 2018, control of the frigate’s rudder and propulsion systems was lost, which caused the ship to drift toward the shore, where it ran aground about 10 minutes after the collision.

Running aground prevented it from sinking in the fjord, but later, a wire used to stabilize the sunken vessel snapped, allowing it to sink farther. Only the frigate’s top masts remain above the surface.
In December 2018, Norwegian explosive-ordnance-disposal divers returned to the ship to remove the missile launchers from its foredeck.
Below, you can see footage of them detaching the launchers and floating them to the surface.
“All diving assignments we undertake require detailed planning and thorough preparation. We must be able to solve the assignments we are given, while providing as low a risk as possible,” diving unit leader Bengt Berdal said, according to The Maritime Executive.
“Our biggest concern [during this mission] is any increased movement of the vessel.”
With the missiles off the ship, all its weapons have been removed. Recovery crews are preparing to raise the ship, putting chains under the hull to lift it on a semisubmersible barge that will take it to Haakonsvern naval base.
The frigate will not be raised until after Christmas, according to The Maritime Executive.

The oil tanker was not seriously damaged in the incident and didn’t leak any of its cargo. Only eight of the 137 crew aboard the Helge Ingstad were injured, but the multimillion-dollar ship was one of Norway’s five capital Nansen-class frigates and was one of Norway’s most advanced warships. (It also leaked diesel and helicopter fuel, but that was contained and recovered.)
The preliminary report found that the warnings to the frigate, which was headed into the port, went unheeded until too late, allowing the outbound tanker to run into it.
According to the report, the frigate’s automatic identification system was turned off, hindering its recognition by other ships in the area, and there was confusion on its bridge because of a change in watch — both of which contributed to the accident.
The preliminary report also raised questions about other ships in the class and the Spanish shipbuilder that constructed it.
The review board “found safety critical issues relating to the vessel’s watertight compartments. This must be assumed to also apply to the other four Nansen-class frigates,” the report said.
“It cannot be excluded that the same applies to vessels of a similar design delivered by Navantia, or that the design concept continues to be used for similar vessel models.”

Defense Department personnel continue to assist in the rescue operations in Thailand to evacuate the remaining four boys and their coach from a flooded cave system, the director of defense press operations said July 10, 2018.
The DOD effort consists of 42 deployed military personnel and one member from the Joint U.S. Military Advisory Group Thailand, Army Col. Rob Manning told reporters at the Pentagon.
“Coordination and interaction with Thai military, Thai government, and other multinational civilians and government entities remains extremely positive and effective,” he said.
U.S. personnel have staged equipment and prepared the first three chambers of the cave system for safe passage, he said. They are assisting in transporting the evacuees through the final chambers of the cave system, and are providing medical personnel and other technical assistance to the rescue efforts, he added.
Saman Kunan died while laying oxygen tanks for a potential rescue of the trapped boys.
Multinational rescue effort
“We continue to fully support the multinational rescue effort and pray for the safe return of the remaining members of the team,” Manning said.
The soccer team and their coach entered the Tham Luang cave in Chiang Rai province in northern Thailand on June 23, 2018, and were trapped by floodwaters. Eight boys have been rescued so far.
Manning paid tribute to former Thai Navy SEAL Saman Kunan, who died after delivering oxygen tanks in the cave.
“The death of the former Thai Navy SEAL illustrates the difficulty of this rescue,” Manning said. “His sacrifice will not be forgotten.”
The crew of a U.S. Navy helicopter reported that the crew of an Iranian vessel pointed a machine gun at them earlier this week.
The incident is the latest in a series of threatening actions by the theocratic regime.
According to a report by FoxNews.com, the MH-60R Seahawk helicopter was vectored in on the small boats after they were attempting to shadow the Nimitz-class aircraft carrier USS Dwight D. Eisenhower (CVN 69). While the helicopter was near the boats, crew members pointed an unidentified machine gun at the helo.
Iran has routinely threatened American ships and aircraft this year. In one incident, the Cyclone-class patrol craft USS Squall (PC 7) fired warning shots at Iranian Boghammer-type small boats.
American and Iranian forces have clashed before, most notably during Operation Praying Mantis in April, 1988. This past January, Iran seized 10 sailors after an engine failure occurred on a riverine boat. A female sailor was recognized for her courageous actions during the incident, which included the detention of the Navy personnel for roughly 15 hours.
The MH-60R is a multi-mission helicopter that operates off surface combatants and carriers. It has a top speed of 180 nautical miles per hour, a crew of three, and can carry Mk 46, Mk 50 or Mk 54 anti-submarine torpedoes or AGM-114 Hellfire air-to-ground missiles. The helicopter can remain aloft for three hours.
Iran has a large force of around 180 small patrol boats. Often armed with heavy machine guns and small arms, these vessels were used during the Iran-Iraq War to attack supertankers. The most notorious of these patrol boats was the Boghammer, a Swedish design that can carry .50-caliber machine guns, a ZU-23 twin 23mm AA gun, or a 12-round rocket launcher.
The Royal Marines piled into helicopters and boats and inserted into Estonian territory, hitting positions on the mainland and on an isolated island, doing their best to inflict maximum casualties on the Estonian Volunteer Defence Force during an exercise designed to see whether that countries tiny military can adequately defend itself against a top-tier foe.
And make no mistake about it, the Royal Marines are true commandos and are top-tier. But the local forces defending the island of Saaremaa included many members who had grown up on the island, and they fought the British to what referees called an Estonian victory. The Royal Marines called it a draw, according to an article in the British publication Plymouth Herald.
Also, in the Royal Marines’ defense, the Estonians were backed up by British Apaches and likely would have lost their key position, and maybe the whole ball game, without that crucial air support.
The Marines successfully landed reconnaissance teams unseen, and those teams were able to operate for 24 hours undetected. Then, dummy raids on one side of the island drew off defenders before the Royal Marines launched their main assault on the opposite side, allowing them to reach their main objective with little contact.
So each side did well. The Royal Marines were able to hit their objective almost undetected, and the Estonians were able to defend it anyway, and that’s good for both sides because, realistically, Estonia and Britain would more than likely fight on the same side in a war.
And the people Britain would liberate Saaremaa from would not be Estonian locals, they would be Russian commandos.
Under the surface of all European war games of the last few years sits the certainty that Russia’s aggression in Ukraine only faded because it became too costly. If former Soviet Bloc countries who want to remain democratic and free are to do so, they have to be ready to fend off a Russian “grey-zone” attack at any time.
Grey Zone describes hostilities across cyberspace and physical terrain that fall just short of war. The successful Russian seizure of Crimea and the attacks into the Donbas region were both grey-zone operations.
President Donald Trump and Defense Secretary James Mattis offered strikingly different perspectives on Russian President Vladimir Putin in the course of just a few hours on June 15, 2018.
Speaking with reporters outside of the White House, Trump blamed former President Barack Obama, not Putin, for the annexation of the Ukrainian peninsula of Crimea in 2014.
“President Obama lost Crimea because president Putin didn’t respect President Obama, didn’t respect our country and didn’t respect Ukraine,” Trump said.
Trump also said it’s “possible” he could meet with Putin summer 2018.
This followed comments Trump made at the recent G7 summit in Canada in which he called for Russia to be readmitted to the group. Moscow was booted from the group (then the G8) due to its annexation of Crimea.
“Whether you like it or not, and it may not be politically correct, but we have a world to run,” Trump said at the time. “And in the G7, which used to be the G8 — they threw Russia out — they should let Russia come back in because we should have Russia at the negotiating table.”
Comparatively, as Trump called for America’s allies to rekindle relations with Russia despite its aggression in Ukraine, Mattis ripped into Putin at a graduation ceremony at the US Naval War College in Newport, Rhode Island.
“Putin seeks to shatter NATO. He aims to diminish the appeal of the western democratic model and attempts to undermine America’s moral authority, his actions are designed not to challenge our arms at this point but to undercut and compromise our belief in our ideals,” Mattis said.
Trump and his top advisers have often spoken of Russia and Putin in decidedly different terms, and he has been widely criticized for praising the Russian leader at various times in the past.
Moreover, the president has repeatedly downplayed Russia’s interference in the 2016 US presidential election, even as his senior advisers have continuously warned that Moscow will meddle in future US elections.
It sometimes seems like military service grants you some sort of extra-sensory bullsh*t detection superpower. This is apparently true in Venezuela, where soldiers were forced to keep a close watch on one another to keep them from deserting as another sham election for the world’s sh*ttiest dictator drew nearer in 2018.
Desertions, rebellions, and treason were rife within its ranks as the army became less and less able to feed and pay its soldiers, much less fight a war with them. The world waited to see what this dumpster fire of a president would do about it.
Nicolas Maduro always looks like he really needs an epi-pen.
When an army is deserting at a rate almost four times as high as previous years, not only does its leadership need to stop the bleeding, but they also need to figure out how to defend their homeland. Nicholas Maduro also needed to figure out how to use them to maintain his grip on power while rigging the 2018 election.
As the soldiers guarding polling places kept an eye out for any terrorists, saboteurs, or actual legal votes, what they probably really thought about is how to ditch that awful job and make more than the two dollars a day the Venezuelan government paid them.
Three faces in this photo are screaming to be anywhere else.
One Sergeant Major who has served for 20 years told Business Insider he hasn’t had a full fridge for a long time. His old Christmas bonus used to buy furniture, clothes, and toys for his family but now can only afford three cartons of eggs and two kilos of sugar. With that kind of depreciation, it’s easy to see why Venezuela is losing more than just a few good men. “President” Maduro blames a conspiracy led by the United States for losing his army – He says the U.S. is planning to invade Venezuela.
If the U.S. intends to invade his country, how will he defend it with a poorly paid, fed, and equipped army? Ask his Grandma to help?
Maduro addressed the entire country, slamming President Donald Trump and the U.S. government for its use of economic force and military threats to force Maduro out of power. He launched a two-day military training exercise, encouraging civilians to enter the armed forces reserve or join civilian militias to help repel a military invasion.
Another means of control are another group of armed civilians, called colectivos. These are fervently pro-Maduro militias who have been trained to keep the local populace in line since the days of Hugo Chavez. Unlike soldiers of Venezuela’s regular Army, there’s nowhere they can defect to: It’s Maduro or death for them.
These civilians are funded by the government and act as a paramilitary group and internal security service. If a military intervention from outside ever does come, they will be systematically hunted down and prosecuted by their fellow Venezuelans for their years of violent reprisals against dissidents and extra-judicial killings.
The First World War brought a level of destruction that the world had never seen before. At the start of the war, only the French, Russians, English, and Italians stood against the Germans, Austro-Hungarians, and the Ottomans with their respective territories/colonies/provinces each filing in under their protectorate states. Every corner of the world was forced to take sides, officially or otherwise.
Neutral nations would be asked politically at first, but were quickly strong-armed into supporting one side or the other. This same fate could have befallen Afghans — who were distrusting of British India to the East and the Allied Russians to the north — if the negotiations hadn’t gone spectacularly wrong.
Too easy, right? This is only the “Graveyard of Empires” we’re talking about here.
In September, 1915, the Germans saw in opportunity in exploiting the Afghan tribes’ strategic advantage against the Allied troops that had left British India to fight in Europe. Persia had been officially neutral, but swung sides depending on who was more in control (Note: This was before the Turkish Invasion of Persia, which would eventually solidify their anti-Ottoman stance). If Afghanistan would join the Ottomans, the Persians would certainly follow. After all, the Afghan people hated the British and most of the ruling parties. All that stood in the way of a Central Powers-controlled Middle East and a wide-open causeway through India was a hesitant Amir Habibullah Khan, then the leader of Afghanistan.
The Ottomans leveraged much religious control over their fellow Muslim nations. Grassroots protests ran rampant in British-controlled India. Things were at a tipping point and all it would take was some sweet talking by a Bavarian officer, Oscar Niedermayer, on official orders from the Kaiser to go win them over. On paper, the plan was flawless.
Don’t worry. Niedermayer maybe won’t screw things up just yet.
Mahendra Pratap, centre, with (left to right) Maulavi Barkatullah, Werner Otto von Hentig, Kazim Bey, and Walter Röhr. Kabul, 1916
Niedermayer and his team traveled to Constantinople to meet up with their Turkish counterparts. Despite being in friendly territory, the mission was to be highly covert — one that, if compromised, could end in death for everyone involved. Yet, when the Turks showed up to the Pera Palace Hotel, they found the Germans sh*tfaced drunk, openly telling everyone that they’re going on an Afghanistan Expedition. Understandably, the Turks said, “f*ck it” and left, unwilling to be part of a botched mission that would have them executed if gone poorly due to the actions of some drunken idiots.
After the disaster in Constantinople, Berlin sent in Prussian diplomat, Werner-Otto von Hentig, to join in. Von Hentig was a consummate professional and had brought with him Raja Mahendra Pratap, an Indian royal who wanted to take control back from the British, to aid in negotiations. Niedermayer took great offense to this and constantly butted heads with von Hentig.
The combined teams finally reached Kabul to start negotiations anew.
And celebrate they did. In only the truest of German manners.
Von Hentig and Pratap made friends with the Afghan ruler. Meanwhile, Afghan print media started stirring up anti-British sentiment. Months went by and negotiations continued. The war had started to cripple the Allies and Russia was on the verge of collapse after the “Great Retreat.”
In December, Amir Habibullah Khan ordered the drafting of treaty of friendship to establish an agreement between Afghanistan and Germany. By April 1916, things were looking good for the Central Powers. The enemy was getting weaker and they were inches away from gaining a strategic ally. They would, of course, celebrate.
The details of the event are still hazy, but it’s widely assumed that they got sh*tfaced once again — this time, in a Muslim country that strictly forbade alcohol. This turned into strong condemnation from Afghan leadership — even those who once supported their cause.
The Niedermayer–von Hentig Expedition was sent packing. Soon after, Persia was invaded by the Turks, which gave rise to a hard-line hatred of the Central Powers. As history shows, the Central Powers lost WWI. Amir Habibullah Khan was assassinated after the war’s conclusion by an anti-British coup that lead into the Third Anglo-Afghan War — which was lost in spectacular fashion.
All of history as we know it may have been rewritten were it not for one fateful night.
When you think of joining the military, a ton of images shoot through your mind. You think of that badass grunt running toward some unnamed, burning city, rifle in hand as aircraft rip through the skies above. When you actually start your service, you’ll quickly realize that reality is a far cry from your fantasy. In fact, grunts don’t even spend all of their time fighting wars.
Some things might surprise you, but then there are a ton of things you never saw coming.
It’s not even that your recruiter lied to you, it’s just that much of life in the military isn’t as advertised on posters or in TV ads. Some of thee surprises are cool, many of them suck, but at the end of the day, they’re what keeps the machine running.
You probably didn’t expect the following when you signed on the dotted line:

If you’re a prospective Marine, then you’ve probably seen Jarhead (maybe one too many times). You know that one part where they train with paintball rounds? Most of us thought it was Hollywood bullsh*t — until we got to do the same. Granted, it doesn’t hurt as bad as they make it seem in the movie, but it’s actually a lot of fun. Hell, it’s probably some of the best training you can get.
You see what the aircraft does with the ammo, though.

Loading ammo onto an aircraft
We’ve all seen videos of jets flying overhead and raining pain onto the ground below. In those moments, with our jaws dropped, we’re thinking, “whoa… that’s so cool.” That is, of course, before you’re the one loading the ammo.
Remember, there are a lot of people behind every dropped bomb.
Some may use their anger more than others.

Feeling emotional extremes of every type
Troops are tough bad*sses — but we’re definitely not emotionless. In fact, what makes veterans so stoic is that they’ve already felt every emotion in its most extreme form. You’ll never be more happy than when you get to sleep in an actual bed after months of sleeping in dirt, you’ll never be as angry as you were in a firefight, and you’ll never be more sad than when you lose a dear friend.
You might even earn their accolades.

Hanging with another country’s troops
You might expect to go to another country and train with their military, but you can’t really foresee the time you’ll spend hanging out with the Germans, Aussies, Koreans — you name it. You’ll quickly realize that you have a lot in common; you share a lot of the same, bullsh*t experiences.
And you all have that one a**hole in your chain of command.
If you’ve got time and you’ll be using that model for a while, why not go all out?
Building a terrain model
Did you ever think that a squad leader would tell you to go out and buy a pack of plastic army men? Probably not.
You also probably didn’t expect to build a terrain model to plan a mission and yet here you are. If you don’t mind spending a little extra time, you can actually have fun with this one.
“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.
