The Tomahawk strike on Shayrat Air Base in western Syria was pretty potent – after all, 59 of the missiles hit the place. But the base still had aircraft taking off and landing within a day of the strike.
That system was called JP233, and while it doesn’t sound very fearsome, if World War III broke out, this was to be a key weapon in shutting down the Warsaw Pact’s air force.
The JP233 was quite a clever armament. According to the “Encyclopedia of Modern Air Weapons,” the system came in two pods. One would be hung in the rear of the aircraft carrying 30 SG357 runway-cratering munitions. Now, President Trump’s tweet that pointed out the ease of repairing runways is accurate. But this is where the second pod comes in.
The second pod, usually hung in front of the first one, carried 215 HB876 area-denial munitions. Or, in a more simple term: Land mines. These diabolical devices were designed to not only take out the trained runway-repair crews, they could also kill the vehicles that make runway repair a quick and simple task.
The Tornado would fly low and fast over the enemy airfield’s runways with the sub-munitions from two sets of pods slung underneath the fuselage scattering all over the place. If the enemy planes were in the air, they had no place to land. If they were on the ground, they were staying there until follow-up strikes could take care of them.
JP233 wasn’t just a one-trick pony. It could also be used on supply bases, highways, docks, railway yards… really just about any place where you wanted to create a bottleneck on land.
Thankfully, World War III never happened. But JP233 did see action in Operation Desert Storm on Iraqi runways. Press coverage at the time, such as a Jan. 23, 1991 article in the Los Angeles Times, blamed the Tornado’s anti-runway mission and use of JP233 for several crashes.
The blog Defence of the Realm, though, notes that of the six RAF Tornados lost during Desert Storm, only one was on a mission using JP233, and its loss was due to a crash during a low-level turn after carrying out a successful strike, not enemy action.
Still, the JP233 took the blame, and between the public-relations black eye, and the 1999 Ottawa Treaty, it was retired. Under the terms of that agreement, all but a few examples sent to museums were destroyed.
The Air Force has grounded 55 F-35s after several pilots reported serious oxygen deprivation during flights.
Air Force spokesman Capt. Mark Graff released a statement Friday noting that in five cases pilots “reported physiological incidents while flying.” Luckily, a backup oxygen system on the F-35 kicked, which allowed pilots to land without further trouble, Defense One reports.
The incidents occurred at Luke Air Force Base in Arizona, marking the second time Air Force F-35s have been grounded in a year.
According to Graff, the fighter jets at Luke Air Force Base will likely be cleared to fly again Monday.
“Wing officials will educate U.S. and international pilots today on the situation and increase their awareness of hypoxia symptoms,” Graff said in a statement. “Pilots will also be briefed on all the incidents that have occurred and the successful actions taken by the pilots to safely recover their aircraft.”
In late March, Bloomberg reported that Navy pilots have suffered bouts of hypoxia because of a loss of cabin pressure, leading to oxygen deprivation. These issues have steadily increased every year since 2010 on all F-18 models, which includes the Super Hornet. Navy officials are still trying to get to the bottom of what they’re referring to as “physiological episodes.”
The Navy has also recently ground its T-45 Goshawk planes after pilots complained of headaches and oxygen deprivation. The problem was so dire that 100 instructor pilots flat-out refused to fly the planes, forcing the Navy to ground all 195 planes in the T-45 fleet.
Air Force F-35s on other bases like Hill Air Force Base and Eglin Air Force Base are still cleared for flying, and next week, a group of F-35s will fly to France for the Paris Air Show. Those F-35s will come from the Hill base.

Round, smooth and iridescent, pearls are among the world’s most exquisite jewels; now, these gems are inspiring a U.S. Army research project to improve military armor.
By mimicking the outer coating of pearls (nacre, or as it’s more commonly known, mother of pearl), researchers at University at Buffalo, funded by the Army Research Office (ARO), created a lightweight plastic that is 14 times stronger and eight times lighter (less dense) than steel and ideal for absorbing the impact of bullets and other projectiles.
ARO is an element of the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory.
The research findings are published in the journal ACS Applied Polymer Materials, and its earlier publication in J. Phys. Chem. Lett. (see related links below)
“The material is stiff, strong and tough,” said Dr. Shenqiang Ren, professor in the Department of Mechanical and Aerospace Engineering, a member of University at Buffalo’s RENEW Institute, and the paper’s lead author. “It could be applicable to vests, helmets and other types of body armor, as well as protective armor for ships, helicopters and other vehicles.”
Round, smooth and iridescent, pearls are among the world’s most exquisite jewels; now, these gems inspire U.S. Army researchers looking to improve military armor.
The bulk of the material is a souped-up version of polyethylene (the most common plastic) called ultrahigh molecular weight polyethylene, or UHMWPE, which is used to make products like artificial hips and guitar picks.
When designing the UHMWPE, the researchers studied mother of pearl, which mollusks create by arranging a form of calcium carbonate into a structure that resembles interlocking bricks. Like mother of pearl, the researchers designed the material to have an extremely tough outer shell with a more flexible inner backing that’s capable of deforming and absorbing projectiles.
“Professor Ren’s work designing UHMWPE to dramatically improve impact strength may lead to new generations of lightweight armor that provide both protection and mobility for soldiers,” said Dr. Evan Runnerstrom, program manager, materials design, ARO. “In contrast to steel or ceramic armor, UHMWPE could also be easier to cast or mold into complex shapes, providing versatile protection for soldiers, vehicles, and other Army assets.”

This is what’s known as soft armor, in which soft yet tightly woven materials create what is essentially a very strong net capable of stopping bullets. KEVLAR is a well-known example.
The material the research team developed also has high thermal conductivity. This ability to rapidly dissipate heat further helps it to absorb the energy of bullets and other projectiles.
The team further experimented with the UHMWPE by adding silica nanoparticles, finding that tiny bits of the chemical could enhance the material’s properties and potentially create stronger armor.
“This work demonstrates that the right materials design approaches have the potential to make big impacts for Army technologies,” Runnerstrom said.
U.S. Fleet Forces (USFF) Command will begin a second round of testing in 2019 on a two-piece organizational clothing variant that offers flame resistance and moves the Navy one step closer to delivering sailors a safe, comfortable, no-cost alternative to the Improved Flame Resistant Variant (IFRV) coveralls, with the same travel flexibility as the Type III working uniform.
USFF conducted the initial wear test on two-piece variants from May through September of 2018 and collected feedback from nearly 200 wear-test participants across surface, aviation, and submarine communities about everything from colors and design, to comfort and options like buttons and hook-and-loop fasteners. The command also received feedback from more than 1,700 sailors in an online survey about colors and design.

Fleet survey responses indicated that sailors liked the functionality of the Type III but would like to see the design in traditional Navy uniform colors. More than 70 percent of E-6 and junior sailors surveyed liked the navy blue blouse and trouser while a khaki version was the preference for chiefs and officers.

“Leaders are listening to the fleet when it comes to this design,” said USFF Fleet Master Chief Rick O’Rawe, a wear-test participant. “We have an obligation to keep our sailors safe in inherently dangerous environments, but we also want to be mindful of their time. This is going to be something that’s safe, easy to maintain, and doesn’t require half-masting of coveralls when it’s hot or having to change clothes every time you leave the ship. Never again should we have to pass the words ‘all hands shift into the uniform for entering port or getting underway.'”

The updated design, which won’t require sailors to sew on components, will be tested by 100 officers and enlisted sailors to see how well it performs from wash-to-wear without ironing, and how it holds up to laundering. The two-piece variant will allow for de-blousing in extreme climates and challenging work environments. An undershirt will continue to be tested with a flame-resistant, moisture-wicking fabric in black.

I have received so much feedback just from wearing the two-piece around the command every day,” said Yeoman 1st Class Kelly Pyron, a wear-test participant assigned to USFF. “The best part is that we’ll be able to transit from the ship and run errands in the two-piece; having one standard underway and in-port across the board will be much more convenient. I am excited to see the wear test moving into the next phase of evaluation.”
Once approved, the new prototype will serve as an alternative to the IFRV coverall for operational commands. The coverall may continue to be the prescribed clothing item for some sailors in applicable work environments.
Pyron expressed, “If a clothing item, that I will not have to buy, can make my life easier while keeping me safe, I’m all for it.”
Ever since the F-35 Lighting II program started experiencing cost overruns – a nice way of saying it was hemorrhaging cash – much has been made of its excessive cost in both time and money. But the F-35 is hardly the most expensive Pentagon weapons system in the history of the Big Green Machine, it’s just that the F-35 is the first one to get the scrutiny that an internet-gifted public can give a Pentagon weapons program.
With the B-21 Raider bomber coming into production soon, it might be a good idea to look back and see the most expensive airframes ever created by the U.S. Air Force. For reference, although the development of the F-35 topped $1.5 trillion, the cost per plane is a relatively minuscule $115 million.
The only caveat to this list are the Presidential planes, commonly referred to as Air Force One. Each of those cost $600 million apiece and would sit at number two on this list, but since they’re a specialty item with only two models in service I opted to make room for others.
Northrop Grumman’s tactical airborne early warning airframe has been in service since the Navy of the 1960s. An upgraded version, the Advanced Hawkeye, flies with the same mission but upgraded avionics, comms, and sensors. This advanced version comes with an advanced price tag, 2 million apiece.
The Kestrel is the only helicopter on this list and is actually no longer in service. At 1 million apiece, it was intended to replace the Marines’ Marine One helicopter for moving the President around (among other missions), but the cost of developing it ballooned out of control quickly and the program was canceled. The models were all sold to Canada for spare parts.
This anti-submarine aircraft is just ten years old and comes with the capability to support early warning systems and surface warfare as well. It can even defend itself in air combat when necessary. All those bells and whistles come at a price though – 6 million.
C-17 Globemaster III
The Globemaster III is Boeing’s air cargo masterpiece. At almost 25 years old, there is no more reliable and maintenance friendly airframe in the Air Force that is also capable of the kind of heavy lifting the U.S. military asks of it. Over the course of its life, a single C-17 will run upwards of 8 million.
Second only in technological advancement to its younger sibling, the F-35, the F-22 Raptor still manages to edge the Lightning II out in many areas, including price tag. At 0 million per aircraft, its radar cross section is that of a steel marble. The F-22 didn’t really need to go out of production (some will even argue the U.S. should restart the program), it’s just that the F-35 is a more versatile, fifth-generation fighter.
At the time of its production, it was estimated to cost 7 million apiece, which would already have made it the most expensive aircraft ever built. But tacking on its much-needed upgrades and refits less than a decade later puts the per unit cost of a B-2 bomber at a whopping .1 billion each.
Lightning Packs, LLC has created what could be a ground-breaking new pack-frame design that appears to float while being carried, reducing fatigue. It may even generate power, the makers say.
“Our ergonomic backpacks use an innovative pulley system to reduce impact forces on the user by 80 to 90 [percent], which reduces exertion and injury,” according to the Lightning Packs website.
Lightning Packs founder and pack inventor Lawrence Rome is a muscle physiology expert, according to the company’s website. He also teaches at the University of Pennsylvania.
“We first designed, built under contract, and delivered a series of ergonomic and electricity-generating backpacks for personnel of the United States Army and Marine Corps. The ergonomic benefits of our design have been field-tested and approved by soldiers themselves,” the website states.
The Army’s Communications-Electronics Research Development and Engineering Center put out a brief video in 2015 to showcase the new pack frame technology.
Yakira Howarth, of CERDEC’S Command, Power and Integration Directorate, said in the video that the frame “generates electricity through rotary motion that we can capture and use to trickle-charge any batteries or electronics that they have on them.”
“Our aim is for a net-zero soldier which means that whatever he is powering that is on him will be powered by what he is carrying on him at the same time,” she continued. “We are supporting tactical power for the small unit so we are continually gathering data and feedback from soldiers so that we can continue to improve the wearability of this working prototype.”
It’s unclear if the Army is still looking at the technology.
Lightning Packs now plans to market its new ergonomic backpack, the “Hoverglide,” on the commercial market, using Kickstarter.com to raise funding.
Using Suspended Load Technology, or SLT, the frame slides up and down as the weared walks to reduce “the accelerative forces that cause injuries and reduce mobility,” according to the website.
“The pack reduces the metabolic energy requirement by 40-80 watts, allowing a wearer to carry 8-12 extra pounds ‘for free,'” the website states.
The Hoverglide will be offered in several models for backpacking, commuting and light hiking. There will also be a tactical model which is about the size of a standard daypack or assault pack, according to the review website Hot-Newtech.
“Our company is ready to produce a pack that enables quicker, easier travel while reducing back pain and injury, [and] with your help, we can make that happen,” the Lighting Packs website states.

The M1126 and M1127 Strykers have provided good service to the Army in the wars since 9/11, where they provided an excellent balance of mobility, protection, and firepower for troops.
However, when you’re potentially facing a fight with Russia, you need a bigger gun. They now will have one.
The United States Army rolled out the “Dragoon” in response to feedback from the 2nd Armored Cavalry Regiment, currently based in Europe, and likely to be on the front lines if the Russian hordes come. According to an Army release, the Dragoon is officially the XM1296 Infantry Combat Vehicle, and features a Mk 44 Bushmaster II, a 30mm version of the M242 25mm chain gun used on the M2/M3 Bradley, the LAV-25, and a number of United States Navy and Coast Guard vessels.
The baseline M1126 Stryker usually had either a M2 .50-caliber machine gun or a 40mm Mark 19 automatic grenade launcher. Both systems are great for dealing with light enemy forces whose best vehicles may be the “technical” — a pickup truck with a heavy machine gun mounted on it. Against a BMP or BTR – never mind a T-80 main battle tank — the firepower comes up short, placing the nine Joes in the back and the Stryker’s two-man crew in more danger.
Some Strykers have more firepower, like the M1128 Mobile Gun System (which uses a 105mm gun) and the M1134 Anti-Tank Vehicle (armed with the BGM-71 TOW missile). The grunts inside the Stryker can also carry and use the FGM-148 Javelin anti-tank missile.
The Army plans to give the 2nd Armored Cavalry Regiment 81 of the XM1296s. Other purchases may likely follow, as there are potential conflicts across the globe. While those units could face long odds in some of those conflicts, those odds won’t be so long with the XM1296 backing the troops up.
The 1911 pistol has been around for over 100 years. It is beloved by many for its ergonomics, accuracy and heavy-hitting .45 caliber round. In fact, some versions are still in service with the Marine Corps as the M45.
When something’s been around for so long, it’s also a safe bet that people are tinkering with its design. You can find 1911s in various calibers aside from its original .45 ACO, including 9mm NATO, 10mm Auto, and .22 long rifle.
In an article at PopularMechanics.com, Ian McCollum of ForgottenWeapons.com noted that during World War II, the Office of Strategic Services wanted something that could allow commandos and other secret agents to kill sentries quietly and at a distance.
This is actually very important because if the sentry sees you and sounds the alarm, he’s won. It doesn’t matter if he’s hit the alarm with his dying effort. That alarm could even be him dying very noisily.
The key to this was a two-part system that could be added to just about any M1911 pistol that was called “Bigot.” The rear portion was inserted through the ejection port. It had to be set up right to allow the M1911’s slide to close. Then, the piston would be screwed in. After that, a variety of darts – or even mini grenades – could be inserted for use in silently dispatching a sentry of the two-legged or four-legged variety. The darts and grenades would be fired by a .25 ACP blank.
Tests with a quickly-made reproduction were kind of iffy (only one-third of the darts broke a glass target eight feet away). It’s probably why the Bigot never saw any real action.
Still, if Buffy needed a little extra edge to dust some vamps or if 007 wants a gadget that makes for great cinematic eye candy, it’s probably a good choice. Watch the video below to hear Ian relate what we know about this nifty-looking piece!
Wondering what it takes to cut the mustard in Special Forces selection?
The time of my first (just) two-year enlistment in the Army was coming to an end. I originally enlisted for the shortest amount of time in the Army in the event that if I really hated it too much I only ever had two years to endure. There were two things that I was positively certain of:
I really DID want to stay in the Army
I really did NOT want to stay right where I was in the Army
It wasn’t a matter of being so fervent about wanting to excel into the ranks of Special Forces soldiers at that time; rather, it was the matter of getting away — far away — from the attitudes and caliber of persons I was serving with at the time in the peace- time Army as it was. I understood, so I thought, that the way to ensure I could distance myself from the regular army aura was to go into Special Forces, namely the Green Berets.
(Special Forces Regimental insignia)
That was a great path forward, but with a near insurmountable obstacle — you had to be a paratrooper! Jumping from an airplane in flight was fine by me, the problem associated with that was that most airplanes had to be really high up before you jumped out of them. I was then as I am still horrendously terrified of heights — woe is me! My fear of altitudes was keeping me from going to Airborne Jump School and stuck in my current morass of resolve.
Well, just two short years in the regular “go nowhere, do nothing” Army and I was ready to jump out of high-in-the-sky airplanes parachute or no parachute. I was ready to jump ship!
Jump School was indeed terrifying despite the small number of jumps, just five, that we were required to make. All of the jumps were in the daytime though mine were all night jumps. All that is required to qualify as a night jump is to simply close one’s eyes. I did. I figured there was nothing so pressing to see while falling and waiting for the intense tug of the opening of the parachute, so I just closed my eyes.
(Every jump can potentially be a night jump, so says I — Wikipedia commons)
There were 25 of us paratroops headed to the Special Forces Qualification Course (SFQC) upon graduation from Jump School. I was the highest ranking man even as an E-4 in the group, so I was designated the person in charge of the charter bus ride from Jump School to Ft. Bragg, NC for the course — of course! I imagined that duty would not entail much on a bus ride of just a few hours. I was shocked when approached by two men from my group who wished to terminate their status as Green Beret candidates.
Well, the course certainly MUST be hard if men are quitting already on the bus ride to the course.
“Sure fellows, but can you at least wait until we get to Bragg to quit?” I pleaded.
Once at Ft. Bragg, it was our understanding that we were on a two-week wait for our SFQC class to begin. Our first week we tooled about doing essentially nothing but dodging work details like cutting grass and picking up pine cones. The second week was an event that the instructors called “Pre-Phase,” a term that I didn’t like the sound of and braced for impact.
“Pre-Phase,” in my (humble) opinion, was a pointless and disorganized suck-athon. It was a non-stop hazing with back-breaking, butt-kicking, physical events determined to crush the weak and eliminate the faint of heart. In the end we had a fraction of the number of candidates that we started with. I noted that of the 25 men I brought over from Jump School, only me and one other very reserved soldier survived. We nodded at each other and shook hands at the culmination of the mysterious Pre-Phase.
“Good job, brother-man!” I praised him.
“Thank you; my name is Gabrial, you can call me Gabe,” he introduced.
“Great job, Gabe — George is my name — please, call me Geo!” I invited.
The documented entry-level criteria included the ability to pass the standard Army Physical Readiness Fitness Test (APRFT) in a lofty percentile, though one I am loath to admit I do not remember. There was also a swim test that was required of us to perform wearing combat fatigues, combat boots, and carrying an M-16 assault rifle.
We did it in the post swimming pool. It was a bit of a challenge but by no means a threat to my status as a candidate. I was nonetheless dismayed at several men who were not able to pass it after having gone through all they had. It was sad.
(Special Forces have a charter for conducting surface and subsurface water operations — Wikipedia commons)
The first month of the SFQC was very impressive to me as a young man barely 20 years old. It was all conducted at a remote camp in the woods where we lived in structures made of wood frames and tar paper — barely a departure at all from the outdoor environment. We endured many (MANY) surprise forced marches of unknown distance, very heavy loads, and extreme speed that were hardly distinguishable from a full run.
Aside from the more didactic classroom environment learning skills of every sort, there were the constant largely physical strength and endurance events like hand-to-hand combat training, combat patrolling, rope bridge construction with river crossings, obstacle course negotiating, living and operating in heavily wooded environments. We learned to kill and prepare wild game for meals: rabbits, squirrels, goats, and snakes. Hence the age-old term for Special Forces soldiers — “Snake Eaters,” a moniker I bore with proud distinction.
(Survival skills are essential in Special Forces — Wikipedia Commons)
We all had to endure a survival exercise of several days alone. There were dozens of tasks associated with that exercise that we had to accomplish in those days: building shelter, starting and maintaining a fire for heat and cooking, building snares and traps to catch animals for food, and building an apparatus to determine time of day and cardinal directions.
Since the same land was used time after time by the survival training, it was understood by the cadre that the land was pretty much hunted out, leaving no animals to speak of for food. Therefore there was a set day and time that a truck was scheduled to drive by each candidate’s camp to throw an animal off of the back. When the animal hit the ground it became stunned and disoriented. We had just seconds to profit from the animal’s stupor to spring in and catch it before it ran away… or go hungry for the duration.
Hence the sundial I built and my track of the days, to have myself in position to capture my animal when the time came. The time and the truck came. I crouched along the side of the terrain road. The cadre slung a thing that was white from the truck. It hit the ground and was stunned. I pounced on what turned out to be a white bunny rabbit.
“Oh… my God!” I lamented earnestly in my weakened physical and mental capacity, “I’ve stumbled into Alice in Wonderland’s enchanted forest… I can’t eat the White Rabbit!”
(He’s late, he’s late, for a very important date — Wikipedia Commons)
Some men were unfortunately unable to capture their rabbits in time before they ran away. One man was overcome by grief at the prospect of killing his rabbit — his only source of companionship. He rather built a cage for it and graced it with a share of the paltry source of food that he had. Me, I was a loner and swung my Cheshire rabbit by the hind legs head-first into a tree. I ate that night in solace and in the company of just myself.
Men who could no longer continue sat on the roadside each morning and waited for a truck, one that I referred to in disdain as the hearse, to be picked up and removed from the course. One of them was carrying a cage lovingly constructed from sticks and vines in which sat therein a nibbling white rabbit. The man was washed out of the course for failing tasks, backed up by quitting. There was no potential for a man to return for a second time if he had quit on his first try — quitting was not an option.
The event that cut the greatest swath through the candidate numbers was the individual land navigation event. It lasted a week or so with some hands-on cadre-lead instruction, some time for individual practice, culminating in a period of several days and nights of individual tests. The movements were long, the terrain difficult, the stress level very high. Every leg of the navigation course was measured on time and accuracy — we had to be totally accurate on every move, and within the speed standard.
(SF troop candidate during Land Navigation Phase of SFQC moves quickly with heavy loads — DVIDS)
I recall a particular night when all of us lay in our pup tents waiting for our release time to begin our night movements. Just as the hour was on us a monumental torrent of rain began to gush down. The men scrambled and clambered back to their tents like wet alley cats. I performed a simple mathematical equation in my head:
time equals distance
hiding in a tent for an undetermined period equals zero time
zero time equals zero distance
choosing one’s personal comfort over time equals failure
I had a Grandma Whipple’s rum-soaked cigar clenched tightly in my teeth; it was lit before the rain but no more, and I assure you most fervently that it was never in any way Cuban! Plowing through the vegetation for many minutes I came to a modest clearing that I came to be very familiar with over the days. It told me that I was thankfully on course for the moment. The rain was tapering off generously and I felt a leg up on the navigation for the night.
I reached for my cigar but there was none there save the mere butt that remained clenched in my teach. To my disgust the waterlogged cigar had collapsed under its weight and lay in a mushy black track down my chin and neck edging glacially toward my chest. There would be no comfort of the smoke, nor deterrence of mosquitoes by the smoke of the Grandma Whipple’s rum-soaked positively non-cuban cigar that night.
More than five months later I sat on my rucksack (backpack) of some 50 lbs just having completed a timed 12-mile forced ruck march, nothing any longer between me and graduation from the SFQC course. There were plenty of things to think of that had happened or did not happen to me over the nearly half-year, though I somehow chose the bus ride from Jump School to Ft. Bragg to ponder. How rowdy and arrogant the crowd had been, all pompously sporting green berets that they hadn’t even earned yet. Me, I had chosen to wear my Army garrison cap — nothing fancy.
I filtered through the events that had taken each man who had not already quit from that arduous bus ride from Jump School. I remember how they had all failed or quit one by one except that one brother whose hand I shook at the end of pre-phase.
Buses pulled up to move us back to some nice barracks for the night, some barrack at least 12 miles away by my calculation. Usually everyone snatched up his own rucksack by his damned self, but on this occasion the brother next to me pulled up my rucksack to shoulder height for me in a congratulatory gesture of kindness.
I in turn grabbed his rucksack in the same manner though with a deep admiration and respect for the man who had come all the way with me from Jump School through the SFQC fueled by reserved professionalism. His name was Gabriel, but I just called him Gabe.
The Air Force will soon operate F-35s with fast-evolving collision-avoidance technology able to help fighter jets avoid ground collisions by using computer automation to redirect an aircraft in the event that a pilot is injured or incapacitated.
In late 2018, the Air Force will fly an F-35 equipped with an existing technology now in F-16s called Air-Ground Collision Avoidance System, or AGCAS.
The system is slated to be fully operational on an F-35A as early as summer, 2019, service officials said.
Preliminary AGCAS development work has been conducted as part of ongoing F-35 development.
“AGCAS development and integration efforts were completed previously on the F-16 post-block aircraft. Lessons learned from the F-16 AGCAS effort will be applied to the F-35,” Air Force spokeswoman Capt. Hope Cronin told Warrior Maven.
An initial flight test on an F-35A is scheduled to occur in late 2018, she added.

AGCAS uses sensors to identify and avoid ground objects such as nearby buildings, mountains or dangerous terrain; AGCAS has already saved lives, senior Air Force officials tell Warrior Maven.
There can of course be a range of reasons why an aircraft might collide with the ground, one of which could simply be that a pilot winds up pulling so many “G’s” that they lose consciousness, a senior Air Force weapons developer said.
The technology calculates where the aircraft is and where it would hit the ground based upon the way it is flying at the time, service officials said. If the fighter jet is flying toward a potential collision with the ground, the on-board computer system will override the flight path and pull the aircraft away from the ground.
Most of the algorithms, developed by Lockheed Martin, are continuously being refined and testing using simulation technologies.
Interestingly, results from a case study featuring test-pilot input on AGCAS details some of the ways pilots can learn to work with and “trust” the system’s computer automation. This question of how pilots would rely upon the system emerged as a substantial concern, according to the research, because the system takes control away from the pilot.
“Understanding pilot trust of Auto-GCAS is critical to its operational performance because pilots have the option to turn the system on or off during operations,” writes an essay about the case study called “Trust-Based Analysis of an Air Force Collision Avoidance System” in “Ergonomics in Design: The Quarterly of Human Factors Applications.”
The essay further explains that results from their study found that AGCAS was deemed far superior by test pilots to previous “warning systems” which are “prone to false alarms,” can “degrade trust.”
“Warning systems require the user to manually respond and thus are not effective when the pilot is incapacitated or spatially disoriented, and the pilot may not always correctly recognize a warning or correctly make the terrain collision evasion maneuver,” the essay writes.

Air-to-Air Collision Avoidance
In a concurrent but longer-term effort, the Air Force is now also working to develop algorithms to stop air-to-air collisions. This technology, developers explain, is much more difficult than thwarting air-to-ground collisions because is involves two fast-moving aircraft, rather one aircraft and the ground.
Envision a scenario where two or more supersonic fighter jets are conducting combat maneuvers in such close proximity, that they come less than 500-feet away from one another — when an automatic computer system engineered into the aircraft takes over and re-directs the fighters, saving lives and averting a catastrophic collision.
This is precisely the scenario scientists at the Air Force Research Lab are hoping to make possible by the early 2020s through an ongoing effort to deploy Air Automatic Collision Avoidance System, or ACAS.
Algorithms are being specifically developed to automatically give computers flight control of an F-16, once it flies to within 500-feet or less than another aircraft, Air Force Research Laboratory developers have told Warrior Maven. The computer systems are integrated with data links, sensors and other communications technologies to divert soon-to-crash aircraft.
There have been several successful tests of the ACAS technology at Edwards Air Force Base, Calif., using F-16s.
So far, the Air Force has conducted 19 “two-ship” flights and one “three ship” flights using the system to prevent collisions, officials said.
The system is also engineered to identify and divert aircraft that are “non-cooperative,” meaning not from the US Air Force, AFRL developers said; sensors are designed to work quickly to detect a flight path or approaching trajectory with the hope of thwarting a possible collision.
While this effort has been underway for quite some time, an Air National Guard mid-air collision of two F-16s in South Carolina last year underscores the service’s interest in rapidly expanding promising collision avoidance technology to incorporate air-to-air crashes as well as air-to-ground incidents. Fortunately, in this instance both pilots ejected safely without injury, multiple reports and service statements said.

NASA has selected a space-based instrument under its Earth Venture Instrument (EVI) portfolio that will make observations of coastal waters to help protect ecosystem sustainability, improve resource management, and enhance economic activity.
The selected Geosynchronous Littoral Imaging and Monitoring Radiometer (GLIMR) instrument, led by principal investigator Joseph Salisbury at the University of New Hampshire, Durham, will provide unique observations of ocean biology, chemistry, and ecology in the Gulf of Mexico, portions of the southeastern United States coastline, and the Amazon River plume – where the waters of the Amazon River enter the Atlantic Ocean.
“This innovative instrument from the University of New Hampshire, selected by NASA, will provide a powerful new tool for studying important ecosystems,” said NASA Administrator Jim Bridenstine. “Its findings also will bring economic benefits to fisheries, tourism, and recreation in the coastline area.”
The instrument was competitively selected from eight proposals considered under NASA’s fifth EVI solicitation released in 2018, with an award of 7.9 million. This is the largest NASA contract award in the history of the University of New Hampshire. Salisbury and his team have proposed the instrument as a hosted payload, for which NASA will provide access to space.
“This award boosts New Hampshire’s profile as a leader in research, academia and innovation, and makes us all immensely proud,” said Senator Jeanne Shaheen of New Hampshire. “Congratulations to the entire team at UNH for winning this highly-coveted contract. I’m excited to see the technology developed through this award. It’s critical that we closely monitor the health of our oceans and assess risks for coastal communities to protect both our environment and our economy. Securing federal resources that invest in scientific research and exploration have been and will continue to be top priorities for me as the Ranking Member of the Senate Appropriations Subcommittee tasked with funding these important programs.”
Coastal ecosystems support humanity in many ways, but they are under increasing pressure from the effects of land use activities, population growth, extreme weather events, and climate change. These pressures can give rise to more frequent, expansive and harmful algal blooms, as well as create areas where dissolved oxygen is severely depleted – both of which are detrimental to tourism, fisheries, and human health.
GLIMR will be integrated on a NASA-selected platform and launched in the 2026-2027 timeframe into a geosynchronous orbit where it will be able to monitor a wide area, centered on the Gulf of Mexico, for up to 15 hours a day. From this vantage point, the hyperspectral ocean color radiometer will measure the reflectance of sunlight from optically complex coastal waters in narrow wavebands. GLIMR will be able to gather many observations of a given area each day, a critical capability in studying phenomena such as the lifecycle of coastal phytoplankton blooms and oil spills in a way that would not be possible from a satellite in a low-Earth orbit. Given its unique spatial and temporal resolution, GLIMR will be highly complementary to other low-Earth orbit satellites that observe the ocean.

“With GLIMR, scientists can better understand coastal regions and develop advanced predictive tools for these economically and ecologically important systems,” said Thomas Zurbuchen, associate administrator of the Science Mission Directorate at NASA Headquarters. “As part of NASA’s commitment to Earth Science, I am thrilled to include this instrument in our portfolio as we keep an eye on our ever-changing planet for the benefit of many.”
EVI investigations are small, targeted science investigations that complement NASA’s larger Earth-observing satellite missions. They provide innovative approaches for addressing Earth science research with regular windows of opportunity to accommodate new scientific priorities. The investigations are cost-capped and schedule constrained. The missions are managed by the Earth System Science Pathfinder (ESSP) program office at NASA’s Langley Research Center in Hampton, Virginia, for the Earth Science Division under the Science Mission Directorate.
The first two Earth Venture Instruments were launched in 2018 and are operational on the International Space Station. The Global Ecosystem Dynamics Investigation (GEDI) is measuring the vertical structure of forests, canopy heights, and their changes – on a global scale – providing insights into how forests are affected by environmental change and human intervention. The ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) is measuring the temperature of plants – information that will improve understanding of how much water plants need and how they respond to stresses such as drought.

The sniper is a lethal combination of patience, discipline, and accuracy. They wait, still and silent, for the perfect moment to strike from afar, eliminating key targets and providing invaluable information to troops on the ground.
While a few snipers in history have had their names enshrined in fame (or infamy, depending on which side of their scope your allegiances lay), the marksman that holds the record for longest-distance confirmed kill is one you’ve never heard of.
In 2017, a sniper with Canada’s Joint Task Force 2 (their equivalent of the U.S. Navy’s SEAL Team 6) shattered the distance record once held by British sniper Craig Harrison. The Canadian deadeye, whose name has been withheld for security purposes, managed to down an IS militant from a staggering 3,540 meters away. For those metrically challenged among us, that’s 11,614 feet — or nearly 2.2 miles — or over 32 football fields, end-to-end, including end zones. The target was so far away that the bullet traveled for a full 10 seconds (at 792mph) before reaching its target.
Yes, we counted.
As if this incredible feat of marksmanship wasn’t impressive enough, according to MilitaryTimes, this kill helped prevent an ongoing ISIS assault on Iraqi Security Forces. This shot exemplifies the importance of the sniper — instead of using bombs or other weaponry that may result in collateral losses, the Canadian weapons specialist was able to lodge a single bullet into just the right spot to stop an assault in its tracks.
So, how’d he do it? Let’s take a look at a few key elements involved.
First, the equipment. It’s reported that the sharpshooter was using a McMillan TAC-50, a long-range anti-materiel and anti-personnel sniper rifle. According to the manufacturer, this rifle has an effective range of 1,800 meters — just over half the distance of the kill. According to reports, the rifle was loaded with 750-grain Hornady rounds, which must be incredibly efficient rounds to keep from wobbling off course at such an immense distance.

More impressive than the equipment, however, is the technique demonstrated by both shooter and spotter. In order to make an accurate shot over that gigantic stretch of land, they had to keep in mind several key factors, including how much the bullet might “drop” over its trip, how much wind might push it off course, and even the speed of the earth’s rotation at the given latitude. To further complicate things, you need to think about atmospheric conditions at the time of shoot — barometric pressure, humidity, and temperature can all affect the bullet’s course. Even the tiniest change can have drastic effects over such a great distance.
At the end of the day, this amazing feat was the junction between incredible mathematics, impeccable coordination between spotter and shooter, and a steady, well-trained hand. We’d like to render a crisp hand salute to you Canadian BAMFs (but not while outside the wire, because you never know who’s watching).

It has nothing to do with oil-rig workers, but it has a lot to do with America’s biggest nuclear weapon; NASA has a plan to deflect asteroids that could end all life on earth. It starts with an enormous, experimental, developing launch vehicle and ends with a massive six-shooter of America’s largest nuclear weapons.
The “Cradle,” as it is called, is out to target any near-Earth object that might get too close. And the first test could come in 2029.
Behold the quintessential devil in these matters, the asteroid Apophis.
On Friday, Apr. 13, 2029, the 1,100-foot asteroid Apophis is going to pass just 19,000 miles away from the Earth. That may not seem very close, but in terms of space stuff, that’s a hair’s breadth away, uncomfortably close. Scientists are pretty sure it won’t hit Earth, but it will be close enough to knock out some satellites. What the close call does bring into question is this: what if there are other near-Earth objects out there that definitely will hit Earth?
That’s where NASA started wargaming with the cosmos. Assuming the asteroid has a mass of a million kilograms and was headed directly for Earth’s center mass, the National Aeronautics and Space Administration decided to figure out what it would take to deflect – not destroy – such a mass.
That’s where nukes come in to play, specifically these B83 nuclear weapons.
Anywhere from two to five years before the projected impact, NASA would send a probe to the asteroid’s surface to read the effects of a possible impact with the another object, test its possible trajectory, and determine the best method of rerouting the celestial projectile from Earth. When the best course of action was determined, the U.S. would launch a series of missiles aboard one of its spiffy new Ares V rockets. There would be three kinds: kinetic, nuclear and solar.
The solar option would be fired into the asteroid’s orbit with a parabolic collector membrane that would focus the sun’s energy onto the object, acting as a kind of thruster to disrupt its path or destroy it into smaller, less destructive versions of itself. The kinetic war head would have an inert warhead on it, and would be designed to literally push the object away using force. The nuclear option would send the largest warhead America has, a 1.2 megaton device in a B83 warhead that can produce a mushroom cloud taller than Mount Everest. They would be detonated close to the object but not right on it or into it.
The idea is to turn its surface into an expanding plasma to generate a force to deflect the asteroid.
There’s the boom.
The reason NASA can’t just outright destroy a near-Earth object was the discussion of a report from NASA and was explored in the early stages of developing this planetary defense.
“The Hollywood scenario solution of shooting several intercontinental ballistic missiles at the incoming rock is fraught with danger. It probably would not be sufficient to prevent impact, raising the additional hazard of radioactive materials from the blast being introduced into the atmosphere,” the report reads.
Hence, the plan is to give it a little push instead.
