A NASA spacecraft that will return a sample of a near-Earth asteroid named Bennu to Earth in 2023 made the first-ever close-up observations of particle plumes erupting from an asteroid’s surface. Bennu also revealed itself to be more rugged than expected, challenging the mission team to alter its flight and sample collection plans, due to the rough terrain.
Bennu is the target of NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission, which began orbiting the asteroid on Dec. 31, 2018. Bennu, which is only slightly wider than the height of the Empire State Building, may contain unaltered material from the very beginning of our solar system.
“The discovery of plumes is one of the biggest surprises of my scientific career,” said Dante Lauretta, OSIRIS-REx principal investigator at the University of Arizona, Tucson. “And the rugged terrain went against all of our predictions. Bennu is already surprising us, and our exciting journey there is just getting started.”
Shortly after the discovery of the particle plumes on Jan. 6, 2019, the mission science team increased the frequency of observations, and subsequently detected additional particle plumes during the following two months. Although many of the particles were ejected clear of Bennu, the team tracked some particles that orbited Bennu as satellites before returning to the asteroid’s surface.

The OSIRIS-REx team initially spotted the particle plumes in images while the spacecraft was orbiting Bennu at a distance of about one mile (1.61 kilometers). Following a safety assessment, the mission team concluded the particles did not pose a risk to the spacecraft. The team continues to analyze the particle plumes and their possible causes.
“The first three months of OSIRIS-REx’s up-close investigation of Bennu have reminded us what discovery is all about — surprises, quick thinking, and flexibility,” said Lori Glaze, acting director of the Planetary Science Division at NASA Headquarters in Washington. “We study asteroids like Bennu to learn about the origin of the solar system. OSIRIS-REx’s sample will help us answer some of the biggest questions about where we come from.”
OSIRIS-REx launched in 2016 to explore Bennu, which is the smallest body ever orbited by spacecraft. Studying Bennu will allow researchers to learn more about the origins of our solar system, the sources of water and organic molecules on Earth, the resources in near-Earth space, as well as improve our understanding of asteroids that could impact Earth.
The OSIRIS-REx team also didn’t anticipate the number and size of boulders on Bennu’s surface. From Earth-based observations, the team expected a generally smooth surface with a few large boulders. Instead, it discovered Bennu’s entire surface is rough and dense with boulders.

The higher-than-expected density of boulders means that the mission’s plans for sample collection, also known as Touch-and-Go (TAG), need to be adjusted. The original mission design was based on a sample site that is hazard-free, with an 82-foot (25-meter) radius. However, because of the unexpectedly rugged terrain, the team hasn’t been able to identify a site of that size on Bennu. Instead, it has begun to identify candidate sites that are much smaller in radius.
The smaller sample site footprint and the greater number of boulders will demand more accurate performance from the spacecraft during its descent to the surface than originally planned. The mission team is developing an updated approach, called Bullseye TAG, to accurately target smaller sample sites.
“Throughout OSIRIS-REx’s operations near Bennu, our spacecraft and operations team have demonstrated that we can achieve system performance that beats design requirements,” said Rich Burns, the project manager of OSIRIS-REx at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Bennu has issued us a challenge to deal with its rugged terrain, and we are confident that OSIRIS-REx is up to the task.”
The original, low-boulder estimate was derived both from Earth-based observations of Bennu’s thermal inertia — or its ability to conduct and store heat — and from radar measurements of its surface roughness. Now that OSIRIS-REx has revealed Bennu’s surface up close, those expectations of a smoother surface have been proven wrong. This suggests the computer models used to interpret previous data do not adequately predict the nature of small, rocky, asteroid surfaces. The team is revising these models with the data from Bennu.

The OSIRIS-REx science team has made many other discoveries about Bennu in the three months since the spacecraft arrived at the asteroid, some of which were presented March 19, 2019, at the 50th Lunar and Planetary Conference in Houston and in a special collection of papers issued by the journal Nature.
The team has directly observed a change in the spin rate of Bennu as a result of what is known as the Yarkovsky-O’Keefe-Radzievskii-Paddack (YORP) effect. The uneven heating and cooling of Bennu as it rotates in sunlight is causing the asteroid to increase its rotation speed. As a result, Bennu’s rotation period is decreasing by about one second every 100 years. Separately, two of the spacecraft’s instruments, the MapCam color imager and the OSIRIS-REx Thermal Emission Spectrometer (OTES), have made detections of magnetite on Bennu’s surface, which bolsters earlier findings indicating the interaction of rock with liquid water on Bennu’s parent body.
Goddard provides overall mission management, systems engineering, and the safety and mission assurance for OSIRIS-REx. Dante Lauretta of the University of Arizona, Tucson, is the principal investigator, and the University of Arizona also leads the science team and the mission’s science observation planning and data processing. Lockheed Martin Space in Denver built the spacecraft and is providing flight operations. Goddard and KinetX Aerospace are responsible for navigating the OSIRIS-REx spacecraft. OSIRIS-REx is the third mission in NASA’s New Frontiers Program, which is managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington.
The top U.S. diplomat in the Pacific told reporters this month strong anti-American statements by the president of the Philippines are more rhetoric than reality, calling them “colorful” and arguing there has been no substantive change in the military relationship with the U.S. ally in the Pacific.
In September, Philippine president Rodrigo Duterte called for severing military ties with the U.S., saying he would end joint Philippine and U.S. counterterrorism missions in Mindanao and stop joint naval patrols in the South China Sea. More recently he has forged a closer relationship with China, saying his country was “separating from the United States” and would be dependent on China “for all time.”
But U.S. officials caution that Duterte has made no moves to sever its ties with the U.S. military and that what he’s saying in public doesn’t match his actions behind closed doors.
“I’m not aware of any material change in the security cooperation between the U.S. and the Philippines,” said Assistant Sec. State for East Asian and Pacific Affairs Daniel Russell during an Oct. 12 interview with reporters in Washington.
“President Duterte has made a panoply of statements … the operative adjective is ‘colorful,’ ” he added. “But what that will ultimately translate to in terms of the ability of the Philippines to work with the United States on issues directly germane to its security and the regional and global challenges that it faces — from piracy to illegal fishing to disaster relief and counterterrorism — is a question that we don’t have an answer to just yet.”
No matter how strongly Duterte denounces the U.S. and its leaders in public, Russell added, the close historical bond between America and the Philippines is something that transcends the politics of the day.
“For our part, we love the Philippines. The relationship between Americans and Filipinos is as warm as you can get,” Russell said. “We’re very close with each other not only by these cultural and personal and historical ties but also by shared interests and by some common threats.”
Russell added that early conversations with the Philippine president, who assumed office in June, indicated he was committed to the U.S.-Philippine military and trade alliance.
But more recently, Duterte has begun to forge closer ties with China despite a decision in July by an international Law of the Sea tribunal that ruled in the Philippines’ favor against China’s control of certain sea lanes close to the island nation — a conflict Russell warned could have led to a war between Manilla and Beijing.
China has rejected the international court’s ruling.
On a recent trip to China, Duterte reportedly forged a $13 billion economic deal with Beijing, calling it the “springtime of our relationship” with China. The apparent shift away from the U.S. and toward the communist nation has caused alarm in some diplomatic circles in the U.S.
But Russell urged calm.
“There’s clearly increased dialogue” between China and the Philippines, Russell said. “In principle that’s a good thing. … As long as that dialogue is … consistent with international law.”
“There’s a lot of noise and stray voltage in the media,” he added. “But ultimately the decisions about the alliance operationally are going to be taken in a deliberate and thoughtful way.”
The U.S. Navy has located the wreckage of a transport aircraft that crashed into the Philippine Sea in November, NHK World reported Jan. 6.
In a statement, the Navy’s 7th Fleet says a team of deepwater salvage experts detected an emergency beacon from the C-2A Greyhound. The wreckage rests on the seabed at a depth of 5,640 meters.
The salvage team had been searching the area since late December.

The crash occurred on Nov. 22nd while the C-2A was flying from a military base in Iwakuni, in western Japan, to the aircraft carrier USS Ronald Reagan.
Eight of the 11 crew and passengers were recovered. The U.S. Navy and Japan’s Maritime Self-Defense Force launched a combined search operation over several days, but failed to locate the three missing.
A quite interesting and somehow weird demo took place on Nov. 21, 2019, on board HMS Queen Elizabeth, hosting the 2019 Atlantic Future Forum (AFF) at anchor off Annapolis, Washington D.C., during UK’s largest aircraft carrier’s deployment to the US.
Ex-Royal Marines Reservist Richard Browning flew with a jet-powered flying suit from the aircraft carrier and welcomed journalists on a boat carrying journalists before returning to the landing platform adjacent HMSQE.
A video of the demo was shared on the Instagram account of Gravity Industries, a British aeronautical innovation company founded by the former Royal Marines reservist.
The view from the yacht is also pretty impressive. Take a look at it:
The Royal Air Force and the Royal Navy are currently involved in the Westlant 19 cruise off the East Coast of the United States to test the F-35B in an operational environment aboard the HMS Queen Elizabeth. After the initial carrier qualification during daylight, the pilots are now undergoing the night carrier qualification process.
The demo was conducted during the AFF 2019 event, a full day conference “bringing together the brightest minds and most influential thinkers-from defence and beyond-to strengthen the US-UK special relationship and encourage collaboration between the public and private sector.”
Browning is not the only one to fly around with a sort-of jet pack. In July 2019, during Bastille Day festivities in Paris, inventor and jet skier Franky Zapata flew a hoverboard in front of French President Emmanuel Macron. Zapata carried a rifle during his demo over French military forces parading down the Champs-Élysées.
The residents alleged they were being intimidated into not fighting the overages, and sources told WATM Navy investigators were looking into the issue.
But according to a Feb. 14 statement from Naval Criminal Investigative Service spokesman Ed Buice, Navy officials closed the inquiry into accusations of over billing “after it became evident the allegations being made were unfounded.”
“No criminal misconduct was discovered,” Buice added in the email statement to WATM.
Buice did not reply to a request for additional comment.
Residents of the San Onofre II neighborhood at Camp Pendleton say they were within the margins for monthly electricity use that would preclude an overage charge.
Military families there pay a lump sum rent that includes a certain amount of energy usage. When they consume less electricity than the allotted amount, they are refunded; when they go over, they receive bills, officials say.
Several residents told WATM that they had seen sudden sharp increases in their electric bills and were threatened with eviction if they didn’t pay up. Many claimed they were rebuffed when they approached base housing officials about the alleged billing problems.
Marine Corps Installations West spokeswoman 1st Lt. Abigail Peterson told WATM in a Feb. 16 email that “all of the official complaints received regarding this situation were addressed and resolved,” adding that Lincoln Military Housing had “implemented a new process to monitor requests to ensure all concerns are addressed in a timely manner.”
“We take feedback very seriously and want to ensure responsible measures are followed to alleviate any issues for our Marines, sailors and their families living here on base,” Peterson said.
Military family advocate Kristine Schellhaas — who originally brought the billing allegations to light — wasn’t satisfied Pendleton’s response, arguing base residents aren’t simply misreading their bills.
“There are systematic flaws with how this program has been implemented,” Schellhaas told WATM. “The facts are that this program needs to get audited.”
The second season of History’s Six is underway and there are a few new faces. Olivia Munn joins the cast as CIA officer Gina Cline. Walton Goggins returns as Richard “Rip” Taggart, who was dramatically rescued in the last season. Led by Barry Sloans’ Joe “Bear” Graves, the team will hit Eastern Europe (even as far as Chechnya) this season to track down a terror network.
Veterans are hard to please when it comes to depicting military life and veterans onscreen. We demand accuracy. We demand realism. Most of the time, we find ourselves disappointed. History’s Six will not disappoint you.
Suspend your disbelief for a moment, fellow veterans. To be perfectly fair, there’s a lot to like and a lot to overlook when it comes to Six — just like any other show on television. Not everyone is going to be a fan. But there is so much more to like from Six. Even the most discerning veteran will find that Six is better than they expected.
1. The realism is relative — and that’s okay
This is something vets have a hard time getting over. Every veteran knows Hollywood gets a lot wrong about the military. There are some egregious examples out there. Some of those make it look like they don’t even try — looking at you, Basic. There are some in which the producers take a few too many liberties for dramatic license, like Jarhead. Despite solid source material, there were just a few things that would never happen in the Marine Corps.
Last season, the show took on Boko Haram, the Sub-Saharan terror organization that was behind the Chibok School Girls Kidnapping (of “Bring Back Our Girls” infamy). The group continues its kidnapping and terror reign in the country to this day. One the show, the SEAL team’s leader was kidnapped by Boko Haram and they spent the season dealing with the aftermath and rescue of Walton Goggins’ character “Rip.”
This season takes the team to Eastern Europe to track a clandestine jihadist cell led by a mysterious figure known as “Michael.” If you haven’t been paying attention to the news, Eastern Europe is the front line to a new Cold War, where Russian and American intelligence agencies work to take down terrorist organizations like ISIS and a resurgent al-Qaeda. Russian security services have been fighting this battle for years. It was only a matter of time before American special operators got involved.
3. Olivia Munn’s character is a great addition
Look, I actually heard someone say, “SEAL Teams don’t have women.” And they don’t. Not yet. History isn’t depicting a female SEAL — she’s a CIA operative and there are many, many female CIA operatives in the real world. History’s SEAL Team Six is getting their “Maya.”
4. The cast were trained by SEALs
Remember that realism thing we were talking about? You are guaranteed to see some outstanding trigger discipline in the cast of Six. Actors Barry Sloane, Kyle Schmid, Edwin Hodge, Juan Pablo Raba, and the rest of the cast went through their own boot camp run by actual Navy SEALs.
The cast of Saving Private Ryan had to go through Capt. Dale Dye’s bootcamp just once, so you might think the cast of Six would only have to do it once, too. Nope. They’re going for every freaking season.
5. It’s about family
Most shows, at their cores, are about some kind of family. But what Six does well is that infuses the family drama that comes with being in a tight-knit family unit. Some media outlet somewhere said it was like a “soap opera,” but anyone who’s ever been in a large family — or a large military workcenter — knows that routinely going to work with people you live with is a soap opera in itself.
6. Action shows are awesome – when done well
I love a good action movie or TV show. I hate a bad one. There’s nothing worse than watching bad lines being read by some marginal actor only to be rewarded by thirty seconds of action maybe every twenty minutes (if you’re lucky). Go watch a recent Steven Seagal movie on Netflix and tell me I’m wrong.
The action in Six is really well-executed, the cast is pretty great, and the visuals are well-done, too.
Season two just started. You have plenty of time to catch up.
There used to be a rough ranking system for people who followed sub warfare. The best diesel submarines are the most quiet when they aren’t running their diesel, followed by the best nuclear submarines, followed by crappy and older subs.
But over the past couple of decades, submarine technology has gotten so advanced that the engine might not even be the limiting factor. Now, sub hunters look for a lot more than a bit of engine or pump noise under the water.

They search for heat trails created by friction between the water and the hull, listen for bubbles that form in the low pressure zones on the backs of propellers, and search for magnetic signatures given off by some sub components. Though modern submarine hulls are often made out of non-magnetic or low-magnetic materials to reduce this signature, some components are naturally magnetic and electrical currents passing through circuits and motors creates small magnetic fields.
Taking a look at these minute details, it’s clear why submarine technology is so heavily guarded. If the enemy finds out that your new motor is quieter but makes a magnetic field that is larger than old designs, they’ll buy better magnetic anomaly detectors (yes, that’s a real name). And if they find out your engine is stealthier than their engine, they’ll try to steal it (looking at you, China).

So, what’s the hierarchy of subs look like right now?
At the top are a few kinds of air-independent propulsion systems, meaning that the subs never or very rarely have to surface to let in oxygen during a cruise. There are two major kinds of AIP submarines, those that use diesel or similar fuel and those that use nuclear power.
In general, the stealthiest subs are generally acknowledged to be non-nuclear boats when they’re running on battery power. Sweden has a sub that fits this bill that is well-regarded across the world and has managed to evade a U.S. carrier group’s anti-submarine screen so well that it “killed” a U.S. aircraft carrier during an exercise. China and Russia also have subs in this category and use them for shoreline defense.

Just beneath that group is nuclear submarines that generate electricity and then use an electric motor to drive the propeller or the pump jets (pump jets are preferred because they are less likely to create cavitation, more on that in the next paragraph). America’s newest submarines fit into this category. They have a small disadvantage against advanced AIP diesel-electric because the nuclear reactors must be continuously cooled using pumps which generate some noise.
Many of America’s subs were created before pump jets matured and have more traditional propellers. At the right depths and propeller speeds, propellers cause cavitation where the water boils in the low-pressure zone near the propeller despite the low temperatures. The telltale bubbles collapse almost immediately, letting good sonar operators follow the noise directly to the enemy sub.
Regardless of whether the sub is using pump jets or conventional propellers, it’s less stealthy when the reactors provide power directly to the propeller. U.S. subs are transitioning to only generating power and then using the electrical power to control the engines. China recently claimed to have developed the components necessary for the same upgrade.

Another step down for diesel subs is when they have low-capacity batteries. Having a low capacity forces the sub to surface and run its engines more often, making them much more likely to be found via radar or satellite.
The oldest diesel subs are also less likely to be designed with sufficiently quiet engines or sound dampening. These older diesel subs are also more likely to be made with steel that can be detected by magnetic anomaly detectors, but at this point, we’re only talking about navies like North Korea’s.
The fact is, however, even at the level of antiquated diesel submarines with direct power going to the engines, small batteries, and little sound dampening, it takes a relatively advanced navy to detect enemy subs.

Sub hunters need solid sonar systems and well-trained operators that can distinguish an enemy sub running quiet from the surrounding ocean noise, especially if the sub moves into a noisy patch of ocean like littoral or tidal areas, where the water rushing over rocks and coral hides the acoustic signatures of all but the noisiest submarines.
While all truly modern navies can do this, not all ships are capable of hunting even older submarines, so older models still give an asymmetric advantage to a nation. But for modern navies like the U.S. and China, the competing sailors have to use every trick in their toolbox to retain an edge.
This is a relatively new development since Chinese subs were known as being laughably loud to U.S. forces just a few years ago. While it’s unclear in the unclassified world just how much China has closed the gap, they’ve made claims that they’re actually slightly ahead of the U.S. This seems unlikely, but China has shown off advanced technologies, like pump jets, that could put its tech within striking distance of the U.S.’
And its subs have twice threatened U.S. carriers, once surfacing well within torpedo range and once shadowing a U.S. carrier near Japan. The U.S. Navy might have spotted the subs and decided to not risk starting a war by engaging it, but it’s also possible that the Chinese subs actually got the jump on them.
Meanwhile, the U.S. has completed its own submarine surprise against China. In 2010, the U.S. surfaced three submarines simultaneously, one each near South Korea, The Philippines, and Diego Garcia, all within range of Chinese forces or the Chinese mainland. Between the three boats, they could carry 462 Tomahawk Land Attack Missiles.
So, it seems that in submarine warfare, the advantage still lies with the subs. But modern submariners are still counting on every advantage that their training, scientists, and engineers can give them, because in a small metal tube hundreds of feet underwater is a horrible time to find out you’re not as stealthy as you’d hoped.
The Army is preparing for the first official flights of two high-tech, next-generation aircraft now being designed with a wide range of abilities to include flying faster, flying farther without needing to refuel, operating in high-hot conditions and having an ability to both reach high speeds and hover like a helicopter.
The new aircraft are part of an Army-led effort, called Joint Multi-Role Technology Demonstrator, aimed at paving the way toward ultimately engineering a new fleet of aircraft for all the services to take flight by 2030.
Construction of two different high-tech, future-oriented demonstrator helicopters is already underway in anticipation of ground testing later this year and initial flight testing next year, Dan Bailey, JMR TD program director, told Scout Warrior in an interview several months ago.
“Things are moving along very well. We are on schedule with exactly what our industry partners have planned,” he said.
While some of the eventual requirements for the new aircraft have yet to be defined, there are some notional characteristics currently being sought after by the program. They include an ability to travel at airplane-like speeds greater than 230 knots, achieve a combat radius of 434 kilometers, use a stronger engine and operate in what’s called “high-hot” conditions of 6,000-feet and 95-degrees Fahrenheit.
“We had set 230 as the speed requirement because we wanted to push the technology. We wanted people to bring new ideas and new configurations to the table,” Bailey said in an interview with Scout Warrior several months ago.
A faster, more manueverable helicopter that can fly farther on one tank of fuel would enable forces in combat to more effectively engage in longer combat operations such as destroying enemy targets or transporting small groups of mobile, lethal ground fighters. The new helicopter will also be designed to use next-generation sensors to find enemies on the move and employ next-generation weapons to attack them, Army officials describe.
The JMR TD technology effort will inform a planned program of record called Future Vertical Lift, or FVL, which will design, build and test a series of next-generation aircraft for the Army, Navy, Air Force and Marine Corps.
“FVL is a high priority. We have identified capability gaps. We need technologies and designs that are different than what the current fleet has. It will carry more equipment, perform in high-hot conditions, be more maneuverable within the area of operations and execute missions at longer ranges,” Rich Kretzschmar, project manager for the FVL effort, told Scout Warrior in an interview several months ago.
.The first flights of the demonstrator aircraft, slated for 2017, will include developmental helicopter/aircraft from two industry teams – Bell Helicopter and a Sikorsky-Boeing team.
TWO HELICOPTER DESIGNS
The Bell offering, called the V-280 Valor, seeks to advance tilt-rotor technology, wherein a winged-aircraft with two rotor blades over each wing seeks to achieve airplane speeds and retain an ability to hover and maneuver like a helicopter.
Bell’s V-280 has finished what’s called a system-level design review where Army and Bell developers refine and prepare the design of the air vehicle.
“They have an air vehicle concept demonstrator that they call the third-generation tilt-rotor. Their fuselage was completed and it is being delivered to Bell for the build-up of the aircraft,” Bailey said.
Along with Boeing, Bell makes the V-22 Osprey tilt-rotor aircraft which is currently praised by military members for its excellent operational performance in recent years. The Osprey has two rotating rotor blades which align vertically when the aircraft is in helicopter mode and then move to a horizontal position when the aircraft enters airplane mode and reaches speeds greater than 280 knots.
The V-280 Valor also has two propellers which rotate from horizontal airplane mode to a vertical position, which allows for helicopter mode. Bell officials have said their new aircraft will be able to reach speeds of 280 knots. Bell and Army officials explain that their V-280 Valor substantially advances tilt-rotor technology.
“What Bell has done is taking its historical V-22 aircraft, and all the demonstrators before that, and applies them to this next-generation tilt-rotor. It is a straight wing versus a V-22 which is not straight. This reduces complexity,” Bailey explained. “They are also building additional flapping into the rotor system and individual controls that should allow for increased low-speed maneuverability.”
The Sikorsky-Boeing demonstrator, called the SB1 Defiant, uses a coaxial rotor system configuration. This is a design structure, referred to as a compound configuration, which relies upon two counter-rotating rotor blades on top of the aircraft and a thrusting mechanism in the rear.
“To make a rotorcraft go fast you have to off-load the rotor lift onto something else or else you run into problems when you try to reduce the speed of that rotor. Typically, you do that with a wing but Sikorsky-Boeing came up with a lift-offset design,” Bailey added.
The pusher-prop on the back of the aircraft is a small propeller behind the counter-rotating rotor heads. It is what can give the aircraft airplane-like speeds. It operates with what’s called positive and negative pitch, allowing the aircraft to lean up or down and move both forwards and backwards, Boeing officials have said.
The JMR TD program and the follow-on FVL effort will also integrate a wide range of next-generation sensors, weapons and avionics, Army officials explained.
Some of these technologies will include a “fly-by-wire” technology allowing for a measure of autonomy or automation so that the helicopter can fly along a particular course by itself in the event that a pilot is injured or incapacitated. This is the kind of technology which could, in the future, allow for unmanned helicopter operations.
Along these lines, the Army is looking for technical solutions or mission equipment which increases a pilot’s cognitive decision-making capability by effectively managing the flow of information from an array of sensors into the cockpit, Army program managers have explained in previous statements on the Army’s website – Army.mil
Army JMR TD development documents describe autonomous capability in terms of the need to develop a Human Machine Interface, HMI, wherein advanced cockpit software and computing technologies are able to autonomously perform a greater range of functions such as on-board navigation, sensing and threat detection, thus lessening the burden placed upon pilots and crew, Army experts have explained.
In particular, cognitive decision-aiding technologies explored for 4th-generation JMR cockpit will develop algorithms able to track, prioritize organize and deliver incoming on- and off-board sensory information by optimizing visual, 3-D audio and tactile informational cues, prior statements on Army.mil have said.
The idea is to manage the volume of information flowing into the aircraft and explore how to best deliver this information without creating sensory overload. Some of this information may be displayed in the cockpit and some of it may be built into a helmet display, Army officials said.
Manned-Unmanned teaming, also discussed by Army developers, constitutes a significant portion of this capability; the state of the art with this capability allows helicopter pilots to not only view video feeds from nearby UAS from the cockpit of the aircraft, but it also gives them an ability to control the UAS flight path and sensor payloads as well. Future iterations of this technology may seek to implement successively greater levels of autonomy, potentially involving scenarios wherein an unmanned helicopter is able to perform these functions working in tandem with nearby UAS.
Integration is key to the Army’s Mission Systems strategy, as the overall approach is aimed at fielding an integrated suite of sensors and countermeasure technologies designed to work in tandem to identify and in some cases deter a wide range of potential incoming threats, from small arms fire to RPGs, shoulder-fired missiles and other types of attacks, Army statements have said.
One such example of these technologies is called Common Infrared Countermeasure, or CIRCM, a light-weight, high-tech laser-jammer engineered to divert incoming missiles by throwing them off course. CIRCM is a lighter-weight, improved version of the Advanced Threat Infrared Countermeasures, known as ATIRCM, system currently deployed on aircraft.
CIRCM, which will be fielded by 2018, represents the state of the art in countermeasure technology, officials said. Future iterations of this kind of capability envisioned for 2030 may or may not be similar to CIRCM, Army developers have said. Future survivability solutions will be designed to push the envelope toward the next-generation of technology, servcie information explains.
The mission equipment for the new aircraft will be tailored to the new emerging designs, service developers said.
Additional countermeasure solutions proposed by industry could include various types of laser technology and Directed Energy applications as well as missile-launch and ground-fire detection systems, Army officials said.
The new helicopter program is also working with its industry partners to develop a new technology which might improve upon the state-of-the-art Modernized Target Acquisition Designation Sight/Pilot Night Vision Sensor, or MTADS, systems currently deployed on helicopters; MTADS sensing and targeting technology provide helicopters thermal imaging infrared cameras as well stabilized electro-optical sensors, laser rangefinders and laser target designators, according to Army statements.
The current, upgraded MTADS currently deployed on aircraft throughout the Army were engineered to accommodate the size, weight and power dimensions of today’s aircraft, dimensions which will likely change with the arrival of a new Air Vehicle built for the new JMR demonstrator aircraft.
JMR Weapons Systems Integration is a critical part of this effort. The JMR aircraft will be engineered to integrate weapons and sensor systems to autonomously detect, designate and track targets, perform targeting operations during high-speed maneuvers, conduct off-axis engagements, track multiple targets simultaneously and optimize fire-control performance such that ballistic weapons can accommodate environmental effects such as wind and temperature, Army documents on the aircraft have stated.
Air-to-Air “tracking” capability is another solution sought by the Army, comprised of advanced software and sensors able to inform pilots of obstacles such as a UAS or nearby aircraft; this technology will likely include Identify Friend or Foe, or IFF, transponders which cue pilots regarding nearby aircraft, Army officials have said.
Technical solutions able to provide another important obstacle avoidance “sensing” capability called Controlled Flight Into Terrain, or CFIT, are also being explored; in this instance, sensors, advanced mapping technology and digital flight controls would be engineered to protect an aircraft from nearby terrain such as trees, mountains, telephone wires and other low-visibility items by providing pilots with sufficient warning of an upcoming obstacle and, in some instances, offering them course-correcting flight options.
Using sensors and other technologies to help pilots navigate through “brown-outs” or other conditions involving what’s called a “Degraded Visual Environment” is a key area of emphasis as well, according to Army officials.
The Army is looking at a range of solutions such as radar, electro-optical equipment, lasers, sensors, software, avionics and communications equipment to see what the right architecture is and how we would integrate all these things together.
PROGRESS THUS FAR
In addition to conducting the first official Army-industry flight of the two demonstrators, the program is working on a Material Development Decision, designed to pave the way for the FVL acquisition program. This effort conducts a thorough examination of all the available technologies and their performance through what is called an “analysis of alternatives.”
A key advantage of a joint FVL program is that it will engender further inter-operability between the services and, for example, allow an Army helicopter to easily be serviced with maintenance at a Marine Corps Forward Operating Base, Bailey explained.
Bell and Sikorsky-Boeing teams are both done with their subsystem critical design review and the components are in fabrication and safety flight testing, Bailey explained.
“Bell has a completed fuselage that is undergoing the nuances of getting landing gear attached to it and holes for wiring. They are complete with their wing build and they are just starting to make it to the engine itself,” Bailey said.
Bell engineers have been mounting the wing to the fuselage.
“It really is starting to look like major components to the aircraft. By May it will likely look like a complete aircraft but it will not have all the subsystems,” he added.
The Sikorsky-Boeing – fuselage is complete as well, Bailey said.
“The transmission, main rotor and hubs have been forged and cast – they are in the process of preparing for final assembly,” he explained.
Both companies we have completed the final design and risk review, which is the government review of their process to say the Army understands the final design and the risks going forward.
“The demonstrators help to inform the feasibility both from the technical and affordability aspects of a future program of record,” Bailey said.
It’s a question that has lasted as long as the Selective Service debate: Should every American serve for a year or two before entering the work force or pursuing higher education?
Arguments have been made for both sides of the case since the last draft in 1973, though the pro-service cause may have just found their strongest and most vocal ally yet — former Joint Special Operations Command chief Stanley McChrystal. Though McChrystal has largely stayed out of the spotlight since his retirement in 2010, he has still been very vocal about this concept, recently penning an op-ed for Time Magazine on the value of national service.
In his article, McChrystal says that the time is ripe for the country to come together to institute a mandatory year of paid national service for young Americans aged 18-28 years. A yearlong commitment would not only instill the values of accountability and responsibility towards citizenship, but will also develop character and leadership traits, he argues.
The retired general does stress, however, that national service should not be directed entirely towards the military. He feels that an open choice between different service organizations needs to exist, allowing for hundreds of thousands of young Americans to have a positive impact beginning in their communities, and resulting in progress on a national level.
This is a view seemingly very common among military veterans, a number of whom have gone on record to discuss the merits of a year of service. It also isn’t the first time McChyrstal has promoted a year of compulsory national service. In 2016, he urged candidates participating in the 2016 presidential race to consider making this idea a reality, and in 2012, the former special operations chief gave a speech to Harvard University on the same topic.
McChyrstal himself is no stranger to service, having joined the Army in 1976 after graduating from West Point. Born into a military family, he rose through the ranks, serving with regular infantry units, on a Special Forces “A-Team”, and eventually the 75th Ranger Regiment, prior to taking command of JSOC in 2003.
Described by former Secretary of Defense Robert Gates as “perhaps the finest warrior and leader of men in combat [he] had ever met,” McChrystal is easily a soldier’s soldier, known for his willingness to be on the frontlines instead of an air conditioned office stateside. His career in the Army ended in 2010 with a truncated stint as the command of US and coalition forces in Afghanistan.
A national service commitment isn’t exactly anything new, especially with many European and Asian nations. Israel and Switzerland are two of the most notable examples, with both countries mandating by law that youth of a certain age are required to register with the military or with a civil service body for a predetermined term. In both countries, the commitment ranges from a year to two years, though some decide to stay around and build a career out of their service terms.
Switzerland, in particular, has utilized conscription to staff its military for decades by having conscripts report for a 260-day service period upon reaching the age of majority. Recruits can choose to serve their entire commitment in 300 continuous days, or train in periods throughout the year, somewhat similar to the National Guard and various branch reserves in the United Sates.
However, should a recruit decide that military service isn’t for them, they can elect to join the country’s civil service as a paid employee for a 390-day period.
Currently, the national year of service topic has yet to be brought up by the White House or Congress, though it still remains a talking point for many, including McChrystal and Arizona Republican Sen. John McCain, a retired Navy attack pilot.
Until meaningful discourse on the subject arises, the retired general and the sitting Senator have worked together to sponsor efforts to afford military veterans and civilian volunteers more opportunities to voluntarily serve their countries in various civil organizations.
Marines manning an entry control point tasked with managing the flow of ambulances heading for the USNS Comfort, a U.S. Navy hospital ship deployed to New York City, ran to the aid of COVID-19 patients whose lives were in danger as their oxygen tanks began to run low in traffic.
On a fairly busy night, the Marines from Lima Company, 3rd Battalion, 2nd Marine Regiment that are tasked with security for the Comfort may deal with an inbound ambulance every thirty minutes. But on April 7, shortly after midnight, they received a urgent call. A nearby hospital was evacuating, and would be sending patients in a convoy of 10 ambulances at once.
Despite being after midnight, the physical limitations of New York traffic and the pier created a traffic bottleneck that slowed the ambulances ability to offload their patients, and as the Marines redirected traffic to allow the most desperate a clear path to the Mercy, it soon became clear that managing the traffic situation wouldn’t be enough.
When a patient in the fourth ambulance in line began to deteriorate as their oxygen tank ran low, the Marines halted all traffic onto the pier, allowing the ambulance to maneuver out of the melee and directly toward the comfort, saving as much as 15 minutes when literal seconds could mean the difference between life and death.
“Us being infantry Marines, we’re all trained in Combat Lifesaver/Tactical Combat Casualty Care,” Marine Sgt. Austin Loppe said after the fact.
“You need oxygen to survive. And even just going a couple minutes without oxygen, the human brain starts losing function and having permanent brain damage for life.”
Loppe’s Marines from Lima company had no time to celebrate, however, as just ten minutes later they received another urgent call. The ambulance at the back of the pack had a patient that was now also running out of oxygen. The Marines jumped into action, redirecting the flow of traffic and getting that ambulance to the front of the line, but as they averted that disaster, an unsettling realization began to set in. It wouldn’t be long before each of these ambulances were out of oxygen, and as a result, patients stuck waiting could suffer brain damage or even die.
“So that wasn’t something that myself or any of my Marines were willing to let happen to an American citizen,” Loppe said.
Navy medical personnel moved quickly to provide additional oxygen tanks which Marines working on the pier picked up and sprinted hundreds of meters to the entry control point (ECP). From there, the Marines manning the ECP grabbed the tanks and took off for the ambulances, distributing them to the medical staff on board each.

Despite the strength of both body and will the Marines had on display that evening, they were unwilling to accept the lion’s share of the credit. LCpl. Colton Flach from Green Camp, Ohio was among the Marines on the pier that night, but he’s quick to credit the Navy and New York City police for their hand in helping to save the patients.
“They’re with us 24-7 on post,” Flach said. “And the moment that we had got that call, I knew that I could count on them to be able to do whatever I needed them to do, and we would do whatever we could to help them as well to get these patients the medical attention that they needed as fast as possible.”
The Marines have played an active role in the Defense Department’s efforts to both bolster governmental responses and ongoing inter-service efforts in places like Guam, where U.S. Navy sailors have been evacuating from the Nimitz-class aircraft carrier USS Theodore Roosevelt due to the spread of the coronavirus on board.
The Marines from Lima Company, 3rd Battalion, 2nd Marine Regiment tasked with security for the USNS Comfort did not wait for orders from higher or for a solution to be presented from others. Instead, they utilized small unit leadership, a skill of significant emphasis within the Corps, to rapidly make command decisions that saved lives.
“It’s kind of hard to put in words. It’s immensely humbling to observe the Marines and actions that small-unit leaders are making, rapid decisions on their own without any sort of tasking or supervision,” Marine Capt. Peter Hofinga, the company commander for Lima Company, said.
“Despite the fact that this is not really in their typical task group, or what they trained to do, they are able to operate within that friction and chaos to help both the Navy-Marine Corps team overall as well as New York City residents.”
The Turkish Armed Forces – or at least elements of them – carried out a coup d’etat in the late-night hours Friday. The intention of the coup was to depose President Recip Tayyip Erdogan. This was quite a shock to most Americans, as Turkey would strike many people to be a very unlikely country for a coup. This is partially due to its membership in the North Atlantic Treaty Organization, and it has in the past petitioned for admission into the European Union. Turkey, though, has had a turbulent domestic history with military involvement.
This should have Americans’ attention. Not only is Turkey next door to the Syrian civil war, as well as on the front lines of the fight against the Islamic State, but American forces, notably the 39th Air Base Wing at Incirlik Air Base, are deployed in-country. The safety of American troops during this time is one area of concern.
Turkey is not the only NATO country to have seen a military coup. Portugal had one in 1974 that toppled a dictatorship (the “Carnation Revolution”), and Greece saw a coup in 1967 that catapulted a notorious military junta into power for seven years. Spain saw attempted coups in 1981 and 1982, both of which were thwarted by the government. France also famously had a close call with a coup in 1958.
Since Turkey’s admission to NATO in 1952, the country has seen two full-fledged military coups take place (in 1960 and 1980) as well as three other military interventions (“memorandums” issued in 1971, 1997,and 2007) in Turkish domestic politics prior to the one that started Friday. Some circles believe that the Turkish military carried out a “stealth coup” in 1993, citing a number of suspicious deaths, including that of then-President Ozal. In most cases, the coups took place when the government was perceived as going too far in an Islamist direction.
Erdogan had faced a number of allegations that he was going in an Islamist direction during his rule. The Turkish government had been reportedly turning a blind eye to fighters joining ISIS. Erdogan’s government also had been arresting members of the military, including some who were purportedly involved in the alleged 1993 coup. Erdogan had also been accused of trying to set up a dictatorship, involvement in electoral fraud, and even imprisoned a former Miss Turkey over comments she made. He may have had this coup coming.
The coup could also have some serious consequences for the Turkish military. The United States has generally issued sanctions against juntas installed via military coup. One notable case was in 2013 when weapons sales were placed on hold in the wake of the coup that deposed Morsi. Egyptian forces facing a fight against terrorists in the Sinai peninsula did not get Apache helicopter gunships that had been provided as military aid.
What effects could this coup have on the Turkish military? Surprisingly, the Turkish military may be better postured than some other countries to weather some sanctions from the United States. Turkey does produce the F-16 Fighting Falcon locally, so its force of over 200 Falcons will still be able to operate. The same is true for its UH-60 Blackhawks, and some other systems.
But the older F-4E and RF-4E Phantoms in the Turkish Ai Force could have readiness issues, as the United States could cut off spare parts for the fighter-bombers and recon planes. The same would also apply for other modern systems Turkey has, including the M270 Multiple-Launch Rocket System, the MGM-140 ATACMS, and the eight Oliver Hazard Perry-class guided-missile frigates that the United States gave to the Turks in the last 1990s. Turkey also could see trouble remaining a partner in the F-35 program for the duration of military rule, and it is an open question whether it would be able to keep its stocks of AGM-88 High-Speed Anti-Radiation Missiles and AIM-120 AMRAAMs operational. Furthermore, the Turkish Navy’s force of SH-60 Seahawk helicopters, which operate off frigates and corvettes, could have problems operating.
Hundreds of North Korean nationals in Europe and Russia are forced to undertake manual labour without breaks, sleep at their workplace, and send their earnings to prop up Kim Jong Un’s lavish lifestyle, BBC Panorama has reported following an undercover investigation.
An unidentified North Korean worker in Vladivostok, Russia, told the programme: “You’re treated like a dog here. You have to eat trash. You have to give up being human.”
He added that he and his fellow workers had to hand over most of their earnings back to North Korea via an intermediary, known as a “captain.”
“Some call it ‘Party Duty.’ Others call it ‘Revolutionary Duty.’ Those who can’t pay it cannot stay here,” he said. “Ten years ago it was about 15,000 Robles ($242/£170) a month, but now it’s twice as much.”
These wages, combined, can generate as much as $2 billion (£1.4 billion) a year, The Washington Post reported.
It is then used to finance Kim Jong Un’s lavish lifestyle and nuclear development programme, North Korea’s former deputy ambassador to the UK said.
Thae Yong Ho, who defected from the regime in 2016, told the BBC: “It financed the private luxury of the Kim family, the nuclear programme, and the army. That’s a fact.”
The North Korean leader recently travelled to China in a bulletproof train containing flat screen TVs and Apple products — a great show of luxury while millions of his citizens remain undernourished or lack basic access to healthcare. He also tested multiple short-range, medium-range, and intercontinental ballistic missiles in 2017.
North Korean slaves in Poland, are also forced to live where they work and aren’t allowed to take any breaks, the BBC reported.
A North Korean supervisor in charge of foreign workers at Szczecin, northwestern Poland, told the programme:
“Our guys are stationed in Poland only to work. They only take unpaid holidays. When there are deadlines, we work without breaks. Not like the Polish. They work eight hours a day and then go home.
“We don’t. We work as long as we have to.”
There are about 150,000 North Koreans foreign workers worldwide, many of whom are in Russia, China, and Poland. About 800 are in Poland, mostly working as welders and manual laborers.
The UN in December 2017, ordered countries to stop authorizing visas to North Korean workers and to send them home within two years.
Poland said it stopped issuing visas to North Korean workers, but that doesn’t mean the activity has stopped.
A Polish manager secretly filmed by the BBC acknowledged that he continued to employ North Korean workers, but complained that it was getting harder to get permits for them.
The Israeli media dubbed it the “Double Miracle In Gaza” — a Hamas fighter took shots at an IDF soldier, hitting him in his cache of grenades. If life were a movie, we know what would happen next.
Luckily life is most definitely not like the movies. The soldier in question (his name was not released by the media) was operating in the Gaza Strip during Operation Protective Edge.
After the murder of three Israeli teens in the West Bank, the IDF launched Operation Brother’s Keeper. The goal was for the IDF to move in and arrest Hamas leadership and the militants responsible for the killings. In response, the terror group fired a number of rockets into Israel from Gaza.
That’s when the IDF moved in on the missile sites.
The soldier’s unit was in Shuja’iyya, in the north of Gaza, where many of Hamas rockets are fired into Israel. Shuja’iyya is a major urban center and is also densely populated. Hamas fired an estimated 140 rockets from the city during the conflict.
His unit was looking for the secret tunnels Hamas uses to sneak into Israel across a blockade. As they moved, an AK-47 round hit a grenade attached to his protective vest. The grenade stopped the bullet and –miraculously – didn’t explode.
The Israelis determined that the bullet was at the end of its effectiveness range, that it was fired from very far away, and didn’t have the energy required to penetrate the vest.
As for the grenade, it’s designed that way. A series of combat incidents involving grenades hitting grenades and exploding in the IDF caused the Israeli military to revamp their grenade design.
After the incident, the IDF cleared Shuja’iyya of Hamas fighters, then bulldozed a number of buildings to collapse the illegal tunnels — tunnels used to smuggle small arms, missiles, and other weapons into Gaza. The IDF then moved on to secure other areas near Gaza’s northern border with Israel.
