Germany introduced the world to the concept of blitzkrieg. One of the key elements to this strategy is to have a force of tanks and mechanized infantry strike deeply and (relatively) quickly behind enemy lines. This means that to successfully execute a blitzkrieg, one needs not only effective tanks, but also good infantry carriers.
For decades now, Germany has relied on the Marder to be the infantry fighting vehicle accompanying Leopard 1 and Leopard 2 main battle tanks. The Marder, which entered service in 1971, packs a 20mm autocannon, has a crew of three, and holds seven troops. However, the Marder is starting to show its age — after all, it’s about a decade older than the Bradley Fighting Vehicle. That’s where the Puma comes in.

Naturally, Germany have a replacement in mind. This vehicle is called the Puma, and it’s slated to bring a few huge leaps in capability to German armor — but nothing is without its drawbacks. Like the Marder, this vehicle has a crew of three, but only carries six grunts in the rear. That’s a slight hit in one area of capability, but the Puma’s firepower makes up for it.
The Puma is equipped with a 30mm cannon (a big step up from the Marder’s 20mm gun). It also packs a 5.56mm coaxial machine gun and a 76mm grenade launcher. It can reach a top speed of 43 miles per hour and go 373 miles on a tank of gas.
The Marder infantry fighting vehicle has served Germany well for almost 50 years.
What’s most notable is that the Puma is only roughly six tons heavier than the Marder, despite the increased firepower. This is due to the use of composite armors that are both more resistant to modern weapons and weigh much less than older armor technology. This enables the Puma to be hauled by the Airbus A400.
Germany is planning to have 320 Pumas delivered by 2020 to replace the Marder. Export possibilities abound, particularly to Canada, which is looking for an infantry fighting vehicles to pair with its Leopard 2 tanks.
According to the Hartford Courant, a Russian naval vessel is operating off the coast of Connecticut. The vessel, described as a “spy ship,” has been operating up and down the East Coast.
A FoxNews.com report identified the Russian ship as the Viktor Leonov, noting that it was also been loitering around Norfolk Naval Station, the largest naval base in the world.
“The presence of this spy ship has to be regarded very seriously because Russia is an increasingly aggressive adversary. It reflects a clear need to harden our defenses against electronic surveillance and cyber espionage,” Senator Richard Blumenthal (D-CT) said in a press release.
The Viktor Leonov is a Vishnya-class intelligence ship. According to GlobalSecurity.org, Vishnya-class vessels are very lightly armed with two SA-N-8 missile launchers and two AK-630 close-in weapon systems. The ship has a top speed of 16 knots, and is loaded with gear for carrying out signals intelligence (SIGINT) and communications intelligence (COMINT).
The Soviet Union built seven of these vessels in the 1980s, and all remain in service with the Russian Navy until 2020, when they will be replaced by a new class of vessels. The Leonov carried out a similar operation in early 2015 with much less fanfare.
Just as dust gathers in corners and along bookshelves in our homes, dust piles up in space too. But when the dust settles in the solar system, it’s often in rings. Several dust rings circle the Sun. The rings trace the orbits of planets, whose gravity tugs dust into place around the Sun, as it drifts by on its way to the center of the solar system.
The dust consists of crushed-up remains from the formation of the solar system, some 4.6 billion years ago — rubble from asteroid collisions or crumbs from blazing comets. Dust is dispersed throughout the entire solar system, but it collects at grainy rings overlying the orbits of Earth and Venus, rings that can be seen with telescopes on Earth. By studying this dust — what it’s made of, where it comes from, and how it moves through space — scientists seek clues to understanding the birth of planets and the composition of all that we see in the solar system.
Two recent studies report new discoveries of dust rings in the inner solar system. One study uses NASA data to outline evidence for a dust ring around the Sun at Mercury’s orbit. A second study from NASA identifies the likely source of the dust ring at Venus’ orbit: a group of never-before-detected asteroids co-orbiting with the planet.
“It’s not every day you get to discover something new in the inner solar system,” said Marc Kuchner, an author on the Venus study and astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “This is right in our neighborhood.”
In this illustration, several dust rings circle the Sun. These rings form when planets’ gravities tug dust grains into orbit around the Sun. Recently, scientists have detected a dust ring at Mercury’s orbit. Others hypothesize the source of Venus’ dust ring is a group of never-before-detected co-orbital asteroids.

Another ring around the Sun
Guillermo Stenborg and Russell Howard, both solar scientists at the Naval Research Laboratory in Washington, D.C., did not set out to find a dust ring. “We found it by chance,” Stenborg said, laughing. The scientists summarized their findings in a paper published in The Astrophysical Journal on Nov. 21, 2018.
They describe evidence of a fine haze of cosmic dust over Mercury’s orbit, forming a ring some 9.3 million miles wide. Mercury — 3,030 miles wide, just big enough for the continental United States to stretch across — wades through this vast dust trail as it circles the Sun.
Ironically, the two scientists stumbled upon the dust ring while searching for evidence of a dust-free region close to the Sun. At some distance from the Sun, according to a decades-old prediction, the star’s mighty heat should vaporize dust, sweeping clean an entire stretch of space. Knowing where this boundary is can tell scientists about the composition of the dust itself, and hint at how planets formed in the young solar system.
So far, no evidence has been found of dust-free space, but that’s partly because it would be difficult to detect from Earth. No matter how scientists look from Earth, all the dust in between us and the Sun gets in the way, tricking them into thinking perhaps space near the Sun is dustier than it really is.
Stenborg and Howard figured they could work around this problem by building a model based on pictures of interplanetary space from NASA’s STEREO satellite — short for Solar and Terrestrial Relations Observatory.
Scientists think planets start off as mere grains of dust. They emerge from giant disks of gas and dust that circle young stars. Gravity and other forces cause material within the disk to collide and coalesce.

Ultimately, the two wanted to test their new model in preparation for NASA’s Parker Solar Probe, which is currently flying a highly elliptic orbit around the Sun, swinging closer and closer to the star over the next seven years. They wanted to apply their technique to the images Parker will send back to Earth and see how dust near the Sun behaves.
Scientists have never worked with data collected in this unexplored territory, so close to the Sun. Models like Stenborg and Howard’s provide crucial context for understanding Parker Solar Probe’s observations, as well as hinting at what kind of space environment the spacecraft will find itself in — sooty or sparkling clean.
Two kinds of light show up in STEREO images: light from the Sun’s blazing outer atmosphere — called the corona — and light reflected off all the dust floating through space. The sunlight reflected off this dust, which slowly orbits the Sun, is about 100 times brighter than coronal light.
“We’re not really dust people,” said Howard, who is also the lead scientist for the cameras on STEREO and Parker Solar Probe that take pictures of the corona. “The dust close to the Sun just shows up in our observations, and generally, we have thrown it away.” Solar scientists like Howard — who study solar activity for purposes such as forecasting imminent space weather, including giant explosions of solar material that the Sun can sometimes send our way — have spent years developing techniques to remove the effect of this dust. Only after removing light contamination from dust can they clearly see what the corona is doing.
The two scientists built their model as a tool for others to get rid of the pesky dust in STEREO — and eventually Parker Solar Probe — images, but the prediction of dust-free space lingered in the back of their minds. If they could devise a way of separating the two kinds of light and isolate the dust-shine, they could figure out how much dust was really there. Finding that all the light in an image came from the corona alone, for example, could indicate they’d found dust-free space at last.
Mercury’s dust ring was a lucky find, a side discovery Stenborg and Howard made while they were working on their model. When they used their new technique on the STEREO images, they noticed a pattern of enhanced brightness along Mercury’s orbit — more dust, that is — in the light they’d otherwise planned to discard.
“It wasn’t an isolated thing,” Howard said. “All around the Sun, regardless of the spacecraft’s position, we could see the same five percent increase in dust brightness, or density. That said something was there, and it’s something that extends all around the Sun.”
Scientists never considered that a ring might exist along Mercury’s orbit, which is maybe why it’s gone undetected until now, Stenborg said. “People thought that Mercury, unlike Earth or Venus, is too small and too close to the Sun to capture a dust ring,” he said. “They expected that the solar wind and magnetic forces from the Sun would blow any excess dust at Mercury’s orbit away.”
With an unexpected discovery and sensitive new tool under their belt, the researchers are still interested in the dust-free zone. As Parker Solar Probe continues its exploration of the corona, their model can help others reveal any other dust bunnies lurking near the Sun.
Asteroids hiding in Venus’ orbit
This isn’t the first time scientists have found a dust ring in the inner solar system. Twenty-five years ago, scientists discovered that Earth orbits the Sun within a giant ring of dust. Others uncovered a similar ring near Venus’ orbit, first using archival data from the German-American Helios space probes in 2007, and then confirming it in 2013, with STEREO data.
Since then, scientists determined the dust ring in Earth’s orbit comes largely from the asteroid belt, the vast, doughnut-shaped region between Mars and Jupiter where most of the solar system’s asteroids live. These rocky asteroids constantly crash against each other, sloughing dust that drifts deeper into the Sun’s gravity, unless Earth’s gravity pulls the dust aside, into our planet’s orbit.
At first, it seemed likely that Venus’ dust ring formed like Earth’s, from dust produced elsewhere in the solar system. But when Goddard astrophysicist Petr Pokorny modeled dust spiraling toward the Sun from the asteroid belt, his simulations produced a ring that matched observations of Earth’s ring — but not Venus’.
This discrepancy made him wonder if not the asteroid belt, where else does the dust in Venus’ orbit come from? After a series of simulations, Pokorny and his research partner Marc Kuchner hypothesized it comes from a group of never-before-detected asteroids that orbit the Sun alongside Venus. They published their work in The Astrophysical Journal Letters on March 12, 2019.
“I think the most exciting thing about this result is it suggests a new population of asteroids that probably holds clues to how the solar system formed,” Kuchner said. If Pokorny and Kuchner can observe them, this family of asteroids could shed light on Earth and Venus’ early histories. Viewed with the right tools, the asteroids could also unlock clues to the chemical diversity of the solar system.
Because it’s dispersed over a larger orbit, Venus’ dust ring is much larger than the newly detected ring at Mercury’s. About 16 million miles from top to bottom and 6 million miles wide, the ring is littered with dust whose largest grains are roughly the size of those in coarse sandpaper. It’s about 10 percent denser with dust than surrounding space. Still, it’s diffuse — pack all the dust in the ring together, and all you’d get is an asteroid two miles across.
Using a dozen different modeling tools to simulate how dust moves around the solar system, Pokorny modeled all the dust sources he could think of, looking for a simulated Venus ring that matched the observations. The list of all the sources he tried sounds like a roll call of all the rocky objects in the solar system: Main Belt asteroids, Oort Cloud comets, Halley-type comets, Jupiter-family comets, recent collisions in the asteroid belt.
“But none of them worked,” Kuchner said. “So, we started making up our own sources of dust.”
Perhaps, the two scientists thought, the dust came from asteroids much closer to Venus than the asteroid belt. There could be a group of asteroids co-orbiting the Sun with Venus — meaning they share Venus’ orbit, but stay far away from the planet, often on the other side of the Sun. Pokorny and Kuchner reasoned a group of asteroids in Venus’ orbit could have gone undetected until now because it’s difficult to point earthbound telescopes in that direction, so close to the Sun, without light interference from the Sun.
Asteroids represent building blocks of the solar system’s rocky planets. When they collide in the asteroid belt, they shed dust that scatters throughout the solar system, which scientists can study for clues to the early history of planets.

Co-orbiting asteroids are an example of what’s called a resonance, an orbital pattern that locks different orbits together, depending on how their gravitational influences meet. Pokorny and Kuchner modeled many potential resonances: asteroids that circle the Sun twice for every three of Venus’ orbits, for example, or nine times for Venus’ ten, and one for one. Of all the possibilities, one group alone produced a realistic simulation of the Venus dust ring: a pack of asteroids that occupies Venus’ orbit, matching Venus’ trips around the Sun one for one.
But the scientists couldn’t just call it a day after finding a hypothetical solution that worked. “We thought we’d discovered this population of asteroids, but then had to prove it and show it works,” Pokorny said. “We got excited, but then you realize, ‘Oh, there’s so much work to do.'”
They needed to show that the very existence of the asteroids makes sense in the solar system. It would be unlikely, they realized, that asteroids in these special, circular orbits near Venus arrived there from somewhere else like the asteroid belt. Their hypothesis would make more sense if the asteroids had been there since the very beginning of the solar system.
The scientists built another model, this time starting with a throng of 10,000 asteroids neighboring Venus. They let the simulation fast forward through 4.5 billion years of solar system history, incorporating all the gravitational effects from each of the planets. When the model reached present-day, about 800 of their test asteroids survived the test of time.
Pokorny considers this an optimistic survival rate. It indicates that asteroids could have formed near Venus’ orbit in the chaos of the early solar system, and some could remain there today, feeding the dust ring nearby.
The next step is actually pinning down and observing the elusive asteroids. “If there’s something there, we should be able to find it,” Pokorny said. Their existence could be verified with space-based telescopes like Hubble, or perhaps interplanetary space-imagers similar to STEREO’s. Then, the scientists will have more questions to answer: How many of them are there, and how big are they? Are they continuously shedding dust, or was there just one break-up event?

Dust rings around other stars
The dust rings that Mercury and Venus shepherd are just a planet or two away, but scientists have spotted many other dust rings in distant star systems. Vast dust rings can be easier to spot than exoplanets, and could be used to infer the existence of otherwise hidden planets, and even their orbital properties.
But interpreting extrasolar dust rings isn’t straightforward. “In order to model and accurately read the dust rings around other stars, we first have to understand the physics of the dust in our own backyard,” Kuchner said. By studying neighboring dust rings at Mercury, Venus and Earth, where dust traces out the enduring effects of gravity in the solar system, scientists can develop techniques for reading between the dust rings both near and far.

Joanna Mendez, former Central Intelligence Agency Chief of Disguise, watched spy scenes from a variety of films and television shows in order to break down how accurate they really are. From Jason Bourne finding his cache of passports and foreign currency to Carrie Mathison’s (Homeland) half-assed “disguise” through airport security, Mendez doesn’t hold back in her opinions and expertise.
During her 27-year career, her position in the CIA’s Office of Technical Service involved providing operational disguises and alias training in hostile theaters of the Cold War from Moscow to Havana. Her duties included clandestine photography and preparing CIA assets with the use of intelligence-collecting equipment like spy cameras, as well as processing the information brought in.
Think “Q” — James Bond Q, not Star Trek…
Now retired, Mendez continues to consult with the U.S. Intelligence community as well as lecture with her husband Antonio Mendez, also a retired intelligence officer, with whom she has published several books about their covert experience including Spy Dust, which reveals “the tools and operations that helped win the Cold War,” and Argo, which would become an Academy Award-winning film of the same name that told the story of “the most audacious rescue in history.”
In the video below, Mendez lets her critiques fly. Check it out:
Former CIA Chief of Disguise Breaks Down 30 Spy Scenes From Film & TV | WIRED
“Carrie’s disguise, which basically consisted of dying her hair…was absolutely ineffective. She’s still Carrie…but with dark hair. She could have cut her hair and restyled it. She could have changed her makeup. She could have put on sunglasses to hide that crazy-eyed look she has…” claps Mendez.
She then jumped to a scene from Alias where Jennifer Garner nails her disguise. “She didn’t just dye her hair — she dyed it outrageously red and then adopted the whole persona to go with it. We could have used that as a training film!” she laughed.
Mendez moves on to Matthew Rhys’ character in The Americans. “He was never trying to look good. He came really close to projecting ‘the little gray man’ that we would talk about at the CIA. You wanted to be forgettable,” she commended.
Mendez then moves on to a “quick change,” the name for a move where an agent clandestinely changes his appearance in 37 seconds. She commented on Mission Impossible III, and in particular discusses why Tom Cruise’s “priest” would have been ethically off-limits.
From Megan Fox in Teenage Mutant Ninja Turtles, to Ansel Elgort in Baby Driver, Mendez breaks down the “quick change” further — and also warns against stealing.
The video covers blending in with the crowd in James Bond — and CIA inventions that helps its agents remain discrete; being assigned a new identity in Spy; cultural customs in Inglorious Bastards; and life-like masks that cover the entire face in order to give the appearance of a completely different face.
The video is highly entertaining, not just because it grabs clips from iconic pop culture favorites (Austin Powers and Sherlock Holmes make appearances) but also because Joanna Mendez has a great, wry humor (“we never tried to disguise ourselves as furniture at the CIA…”).

British Lt. Col. Terence Otway and his men were to be charged with assaulting the Merville battery on June 6, 1944, at the height of the D-Day invasions of occupied France. For their mission – as well as the overall invasion – secrecy was of the utmost importance, so Otway wanted to ensure his men held that secret close and wouldn’t divulge anything under any circumstances.
So he turned to one of the oldest tricks in the intelligence-gathering book to test their mettle: using women to try to draw the information out of them.
The Merville Gun Battery.
Otway and the British 9th parachute battalion were going to assault the series of six-foot-thick concrete bunkers that housed anti-aircraft guns, machine gun emplacements, and artillery from a special artillery division. In all, 150 paratroopers would attempt to take down 130 Germans in a hardened shelter. Since the assault would come just after midnight and well before the main landings, operational security was paramount. The Lieutenant Colonel decided to test his men to see if they could be trusted with the information.
According to the 2010 book “D-Day: Minute by Minute,” Otway enlisted the help of 30 of the most beautiful women of the Women’s Auxiliary Airforce and sent them out to the local pubs with the mission of trapping his men into divulging their secret plans. It was an important test; if the men of the 9th weren’t able to take down those guns, the entire landing might be in jeopardy.
Otway in 1944.
But Otway would be pleased with the discipline of his men. Throughout the nights, they caroused as they always had, drinks in hand, singing the night away. But not one of Otway’s men ever gave up their secret. The attack would go on as planned. His 150 now-proven loyal men landing in the area by parachute and by glider that day in June. Even though the winds disbursed the fighters throughout a large area, they still managed to take down the gun site, albeit taking heavy casualties in the process.
After the Merville Gun Battery was down, the exhausted and depleted British paratroopers then moved on to secure the occupied village of Le Plein. Their assault on the guns cost them roughly 50 percent of their total strength – but they were able to accomplish their mission because of the total secrecy surrounding it from lift off to completion.
Soldiers from 9th Hospital Center, 1st Medical Brigade provided lifesaving medical intervention to casualties involved in an accident on July 10, 2019.
9th Hospital Center soldiers were conducting convoy operations along one of the post’s isolated training areas when they noticed a dark, brooding cloud of towering smoke from a rolled over truck.
As the convoy got closer to the smoke, they noticed an accident that involved two vehicles and one casualty on the road.
“When we got closer, we realized the extent of the accident,” said Cpt. Jillian Guy, commander of Headquarters and Headquarters Company, 11th Field Hospital. “Everyone quickly realized that we were the first responders. Our main priority was to move the first casualty away from the burning vehicle and save his life.”
The convoy made a hasty stop and the soldiers quickly approached the first casualty bystanders had removed from the burning vehicle.
“My thought running up to the scene was to get him away from the burning vehicle as soon as possible and to control the bleeding,” said Sgt. 1st Class Matthew Newell, acting first sergeant for 11th Field Hospital. “I was also thinking that we didn’t know if he had injured his spine, so I knew we needed to use cervical spine precautions as soon as we got to him before we could move him.”
Medics took the lead relocating the casualty further from the burning vehicle using cervical spine precautions. Shortly afterwards, the vehicle’s fuel compartment exploded.
Once the casualties were removed from immediate danger, medics began providing aid to the more severely injured casualty.
“Soldiers swiftly delivered care to the first casualty applying a tourniquet for open bilateral femur fractures,” Guy said. “I saw the second casualty walking around disoriented so I grabbed two medics to help treat him.”
Medics applied tourniquets to the first casualty proficiently to control the bleeding and provided airway management and trauma care. The second casualty suffered from a suspected traumatic brain injury and facial trauma. The medics treated and stabilized both casualties until the emergency medical services arrived.

Even after the EMS arrived, Newell, Sgt. Eric Johnston, combat medic team leader and Sgt. Mariela Jones, platoon sergeant, remained and continued to provide help.
“We were starting fluids, bandaging the wounds and placing the casualty on a spin board,” Newell said. “Once he was on a spin board, Sergeant Jones moved to provide airway until he was placed on a helicopter.”
The intervention did not stop until the casualties were evacuated. The first casualty was air evacuated by Baylor Scott White, and the second was taken to Carl R. Darnell Army Medical Center by the EMS.
“The medics from three different companies quickly became one cohesive unit,” Guy said. “I have never been more proud of everyone on scene. Even the non-medical MOS soldiers did an amazing job with crowd control, driving vehicles safely to the scene and comforting others who had seen the trauma.”
When soldiers came across a situation that needed immediate aid, they reacted expeditiously and saved the lives of those casualties. Military police and EMS commended the Soldiers for their quick reaction, professionalism and proficient medical skill set.
9th Hospital Center soldiers are prepared to provide expert medical care at moment’s notice and they will continue to train in order to stay ready.
“Tragedy can happen at any time and you need to be prepared,” Johnson said. “It was an eye opening experience that nobody was expecting.”
Sure, we all love the “Brrrrrt” of America’s A-10 Warthog — the legendary close air support plane that’s become the terror of Taliban insurgents and Iraqi bad guys alike.
But before the A-10 was the OV-10 Bronco. And while not a 100 percent close air support plane and tank killer like the A-10, the Bronco could deliver it’s own version of hurt when soldiers and Marines were in a pinch.
It’s rugged, powerful and can land just about anywhere with its beefed-up landing gear and high wing. In fact, it was even tested aboard the carrier USS John F. Kennedy in 1968 — without arresting gear.
Since it was retired in the 1995, the OV-10 has experienced a bit of a resurgence these days, with many in the special operations community, Army and Marine Corps calling for a “low and slow” light attack aircraft that can carry more, fly faster and orbit for longer than a helicopter, at a lot less cost than a sophisticated fighter like the F-35 Lightning II or even the aging A-10.
Heck, it even has a small cargo bay for gear and troops.
While there are other options out there, the OV-10 had been in the post-Vietnam inventory for years and still has a solid following in the services. In fact, U.S. special operations troops tested a NASA-owned Bronco recently for several of its missions and, according to an active duty aviator with knowledge of the tests, they loved it.
And if the Marine Corps or Navy says the OV-10 isn’t for them because it can’t land on a carrier? Well, here’s the evidence that it can.
Now you can do the Mario saves Princess Peach workout on a daily basis, thanks to Boston-based computer programmer Ian Albert and Mental Flossmagazine. After a reader asked the magazine how many miles the Italian duo had to run, jump, and swim to get to the Princess, they were actually able to calculate it using some simple standard measurements.
There are some ground pounders out there who probably do harder workouts for fun.
Not to take anything away from your childhood or anything.
Mental Floss’ Nick Green took the maps created through Ian Alberts screenshots of the game, calculated how large Mario and Luigi would be as normal human beings – that is, using their pre-mushroom growth hormone size – a human with their feet slightly more than shoulder width apart, an average of 26 inches.
Then, using no bonus areas or warp tunnels, Green calculated the distance from Mario’s starting point to saving the princess, relative to that 26 inches between his feet. The final tally comes to 17,835 feet – 3.4 miles. Barely more than running a 5K fun run, though this number increases to 3.7 miles if you also calculate running all the bonus areas.
Super Mario PT will not be coming to your console anytime soon.
If we were going to make this a partial triathlon, then calculating the swimming distance would be 371 feet, roughly eight laps in an Olympic-sized pool, and another 344 feet with the bonus areas, so around 15 laps.
Keep in mind this is just running and swimming straight through, without calculating the physical toll of jumping, climbing stairs, crawling in tubes, and murdering birds and turtles or of running in a lava-filled enclosed castle. There’s no doubt that rescuing the princess would be a little more difficult than we’re making it out to be, but the Princess Rescue Workout would still be short work for many military members.
A longtime saying in war is that artillery is the king of the battlefield.
But some artillery are better than others, but the best are those that can drive themselves to battle.
For a long time, all artillery was towed. First the towing as done by horses, then by trucks or other vehicles. But there was a problem. The artillery took a while to set up, then, when the battery had to move — either because troops advanced or retreated – or the enemy found out where the artillery was located, it took time to do that.
Fighter pilots say, speed is life.” Artillerymen would not disagree. Towed artillery had another minus: It had a hard time keeping up with tanks and other armored fighting vehicles.
The way to cut the time down was to find a way a howitzer could propel itself. The advantage was that these guns not only could support tanks and other armored units, but these guns often had an easier time setting up to fire. They could also be ready to move much faster, as well.
This ability to “shoot and scoot” made them much harder to locate.
Most self-propelled howitzers fire either a 152mm round (usually from Russia and China, but also from former communist countries like Serbia) or a 155mm round (NATO and most other countries). Often these guns are tracked, but some have been mounted on truck chassis, gaining a higher top speed as a result.
Some of the world’s best self-propelled howitzers include the American-designed M109A6 Paladin, the Russian 2S19, the South Korean K9 Thunder, and the German PzH-2000.
You can see the full list of the ten deadliest self-propelled howitzers in the video below.
A U.S. military plane carrying a second batch of ventilators to Russia landed in Moscow on June 4, as part of a $5.6 million humanitarian donation to help the country cope with the COVID-19 pandemic. The U.S. ambassador to Russia, John Sullivan, said the shipment contained 150 ventilators made in the United States.
The Navy is now strengthening and extending conceptual design deals with shipbuilders tasked with refining structures and presenting options for a new Navy multi-mission Guided Missile Frigate — slated to be ready for open warfare on the world’s oceans by the mid 2020s.
Navy envisions the Frigate, FFG(X), able to sense enemy targets from great distances, fire next-generation precision weaponry, utilize new networking and ISR technologies, operate unmanned systems and succeed against technically advanced enemies in open or “blue” water combat, according to service statements.
In early 2018, Naval Sea Systems Command chose five shipbuilders to advance designs and technologies for the ship, awarding development deals to General Dynamics Bath Iron Works, Austal USA, Huntington Ingalls, Marinette Marine Corporation, and Lockheed Martin.
The service has now modified these existing deals, first announced in February 2018, to enable the shipbuilders to continue their conceptual design work and “mature their proposed ship design to meet the FFG(X) System Specification,” according to the deal modifications.
The Navy expects that new weapons and sensors will better enable the ship to destroy swarming small boat attacks, support carrier strike groups, conduct dis-aggregated operations, attack enemies with an over-the-horizon missile, and engage in advanced surface and anti-submarine warfare, service statements specify.
Lockeheed Martin’s conceptual design for the FFG(X).
“These Conceptual Design awards will reduce FFG(X) risk by enabling industry to mature their designs to meet the approved FFG(X) capability requirements. The Navy has not changed its FFG(X) capability requirements,” Alan Baribeau, spokesman for Naval Sea Service Command, told Warrior Maven.
The Navy hopes to expedite development to award a production contract in 2020 and ultimately deploy the new ship in the early to mid-2020s. For this reason, bidders were required to submit designs that have been “demonstrated at sea” and already paired with a shipyard for rapid production, according to the previous service solicitation.
“The Conceptual Design effort will inform the final specifications that will be used for the Detail Design and Construction Request for Proposal that will deliver the required capability for FFG(X),” the Navy’s contract announcement said.
Service developers seem to be heavily emphasizing sensor networking, weapons integration and targeting technology as it navigates this next phase of development.
“The FFG(X) small surface combatant will expand blue force sensor and weapon influence to provide increased information to the overall fleet tactical picture while challenging adversary Intelligence, Surveillance, Reconnaissance, and Tracking (ISRT) efforts,” Naval Sea Systems Command FFG(X) documents said.
The “blue force sensor” language is explained by Navy developers as integral to the Navy’s Distributed Maritime Operations Concept which, as evidenced by its name, seeks to enable a more dispersed and networked attack fleet suited for dis-aggregated operations as needed.
Also, by extension, longer range sensors will be needed to identify enemy attackers now equipped with long-range precision strike weapons and enable command and control across vast distances of open water and coastal patrol areas.
The Navy vision for the ship further specifies this, saying the “FFG(X) will be capable of establishing a local sensor network using passive onboard sensors, embarked aircraft and elevated/tethered systems and unmanned vehicles to gather information and then act as a gateway to the fleet tactical grid using resilient communications systems and networks.”
Along these lines, the Navy’s FFG(X) Request for Proposal identifies a need for a netted sensor technology called Cooperative Engagement Capability (CEC).
CEC is an integral aspect of key emerging ship-defense technologies aimed at “netting” sensors and radar technologies in order to better identify and destroy approaching threats such as anti-ship missiles, drones and enemy aircraft.
“CEC is a sensor netting system that significantly improves battle force anti-air warfare capability by extracting and distributing sensor-derived information such that the superset of this data is available to all participating CEC units,” a Raytheon statement said.
Current analysis is no longer restricted to the idea of loosely basing the “hull design” upon the LCS, as was previously the case, Navy officials say.
Designs for the ship no longer merely envision a more “survivable” variant of an LCS. Previous FFG(X) requirements analyses conducted by a Navy Frigate Requirements Evaluation Team examined the feasibility of making the ship even more lethal and survivable than what previous plans had called for, Navy officials said.
Existing plans for the Frigate have considered “space armor” configurations, a method of segmenting and strengthening ship armor in specified segments to enable the ship to continue operations in the event that one area is damaged by enemy attack. Discussions for Frigate technologies have included plans for an MH-60R helicopter, Fire Scout drone and ship defense technologies such as SeaRAM.
The Navy already plans for the new Frigate to be integrated with anti-submarine surface warfare technologies including sonar, an over-the-horizon missile and surface-to-surface weapons, which could include a 30mm gun and closer-in missiles such as the HELLFIRE. An over-the-horizon missile chosen by the Navy for the LCS is the Naval Strike Missile by Kongsberg-Raytheon.
Navy plans for the FFG(X) also call for advanced electronic warfare tech along with both variable depth and lightweight sonar systems.
The new ship may also have seven 11-meter Rigid Inflatable Boats for short combat or expeditionary missions such as visiting, searching and boarding other ships.

In addition, Navy developers explain that the ship will be configured in what’s called a “modular” fashion, meaning it will be engineered to accept and integrate new technologies and weapons as they emerge. It certainly seems realistic that a new, even more survivable Frigate might be engineered with an additional capacity for on-board electrical power such that it can accommodate stronger laser weapons as they become available.
The Navy’s Distributed Maritime Operations Concept builds upon the Navy’s much-discussed “distributed lethality” strategy. This strategic approach, in development for several years now, emphasizes the need to more fully arm the fleet with offensive and defensive weapons and disperse forces as needed to respond to fast-emerging near-peer threats.
Part of the rationale is to move back toward open or “blue water” combat capability against near peer competitors emphasized during the Cold War. While the strategic and tactical capability never disappeared, it was emphasized less during the last 10-plus years of ground wars wherein the Navy focused on counter-terrorism, counter-piracy and things like Visit Board Search and Seizure. These missions are, of course, still important, however the Navy seeks to substantially increases its offensive “lethality” in order to deter or be effective against emerging high-tech adversaries.
Having longer-range or over-the-horizon ship and air-launched weapons is also quite relevant to the “distributed” portion of the strategy which calls for the fleet to have an ability to disperse as needed. Having an ability to spread out and conduct dis-aggregated operations makes Navy forces less vulnerable to enemy firepower while. At the same time, have long-range precision-strike capability will enable the Navy to hold potential enemies at risk or attack if needed while retaining safer stand-off distance from incoming enemy fire.

The Chinese People’s Liberation Army is pushing ahead with its ambitious plan to build a modern, capable “blue-water navy” that will dominate China’s neighbors, showcase Beijing’s rising power and one day even threaten the US Navy.
China has one aircraft carrier in operation, another undergoing sea trials, and a third one in development, putting the Chinese navy on track to begin fielding carrier task forces as it gains experience with carrier operations.
Type 001 Liaoning
China’s Type 001 Liaoning, a refitted Soviet “heavy aircraft-carrying cruiser,” is the sister ship of Russia’s Admiral Kuznetsov aircraft carrier. This vessel was officially commissioned into the PLAN in 2012, and it was declared combat ready in 2016, even though its primary purpose is to serve as a training platform.
“For what the Liaoning is, I think it’s pretty good at its job,” Matthew Funaiole, a fellow with the China Power Project at the Center for Strategic and International Studies, previously explained to Business Insider.

The Chinese “purchased it, they reverse engineered it, they used it to design their second aircraft carrier, and now they are using it as a training vessel to sort out carrier operations, figure out how to integrate it into the fleet, and determine what kind of supporting vessels they need to put with the carrier for their mission,” he added, suggesting that training with the Liaoning could potentially inform future carrier task force decisions, among other important choices.
Type 001A and Type 002
The Type 001A, a domestically-produced version of the Liaoning undergoing sea trials, features some improvements over its predecessor, but it is the Type 002, the third carrier in development, that could be a “huge step forward” for the Chinese PLAN, according to Funaiole.
It is with these next two carriers that the world may start to see China push ahead with the next stage of carrier operations, specifically task force creation for joint operations.
Imagining future Chinese carrier battle groups
The Liaoning has set sail with a number of different escorts over the years, but the deployment of effective task forces will require a bit more time, experts argue.
“To create really meaningful carrier task groups is probably five years out, and a lot of it depends on their actual experience with combat aircraft,” Tony Cordesman, the Arleigh A. Burke Chair in Strategy at CSIS, told BI.
Chinese carriers lack the ability to go toe-to-toe with the US Navy, although they have an advantage in waters near China because Chinese ballistic missiles “can reach out almost to the limits of its claims and actually potentially hit a carrier-sized object with a conventional warhead,” he explained, adding that observers should not “make the assumption that to make the carriers useful, they have to reach a level of competition that could deal with a really sophisticated US threat.”
The primary task for Chinese carriers is the prestige mission, experts note, suggesting that the Chinese aim to send a message to their neighbors.
“The prestige mission is probably the most important one. They are going to be going out to show the flag,” Bryan Clark, a naval expert and senior fellow at the Center for Strategic and Budgetary Assessments, told Business Insider.
Areas where Chinese carriers could matter most
There are several areas of potential interest, with two being the contested waterways around China and the Indian Ocean.
In local waterways, such as the East and South China Seas, Chinese carriers advance Chinese interests by simply serving as displays of military might. “When it comes to projecting power against smaller states, it’s often a matter of demonstrative action or influence,” Cordesman explained.
Countries in the region may soon find themselves “dealing with a China that can actually project carrier forces and air power now into areas that they’ve never been able to really project air power before.” With that capability, which can be achieved relatively quickly, China can make “a very real difference in regional power and influence.”
But China could also extend its reach beyond its immediate neighborhood. Clark expects to see China eventually deploy carrier task forces to the Indian Ocean given Beijing’s growing interest in the area.
“Within the South and East China Sea, they have lots of land-based systems, aircraft, and ships they can deploy out there under the cover of their shore-based air defenses and surface missiles,” he remarked, “They need the navy to go over and help protect Chinese interests in the Indian Ocean and along the littorals.”
China could, for instance, be looking at projecting military power in the Strait of Malacca and along East Africa from Djibouti down to Mozambique and Madagascar, where China has notable business interests. China has already, via legitimate and questionable means, developed a string of ports in Sri Lanka, Djibouti, and Pakistan to support such operations.
Type and number of ships in a carrier task force
“I imagine a Chinese CTF may be a Type 055, a Type 054, and then maybe three or four Luyangs because they want to make sure they’ve got a lot of air defense capacity and because they want to make it look like a formidable threat,” Clark explained, referring to China’s new cruiser, as well as the country’s capable frigates and destroyers.
“This includes, in some ways, the classic mix that we would use,” Cordesman told BI.
A typical US Navy carrier strike group includes the carrier and five ships — one cruiser and four destroyers. But China might deploy even greater numbers.
“It’s likely they are going to want to have more surface combatants than even we might have put with a ship,” Clark said, pointing to the need for increased air defense capacity due to the limited number of vertical launch system (VLS) cells on Chinese surface ships, which can be loaded with missiles to intercept incoming threats and to strike ships.
A Chinese carrier task force would also require support ships, like ammunition oilers, for certain deployments.

Type 054/A Jiangkai I/II frigates
The 4,000-ton Type 054A warships, Chinese stealth frigates designed for fleet defense, are armed with HQ-16 medium-range air defense missiles and a 32-cell VLS in the forward section that is able to fire anti-ship missiles, air defense missiles, and anti-submarine torpedoes, according to The Diplomat.
The first Type 054A was commissioned into the PLAN in 2005, but China has made some modifications to the ship in recent years. For instance, some of the newer ships of this class feature variable depth sonar and towed array sonar, as well as an improved close-in weapon system.
China is reportedly in the process of developing a 5,000-ton variant, the Type 054B Jiangkai III-class frigate.
Type 052C/D Luyang II/III destroyers
These ships, especially the newer Type 052D, are said to be similar to the US Navy’s Arleigh Burke-class guided-missile destroyers.
Commonly referred to as the “Chinese Aegis,” the Type 052D destroyers feature a 64-cell VLS, with each cell capable of carrying up to four missiles, including the lethal YJ-18 anti-ship cruise missile and the HQ-9 surface-to-air missile. A US destroyer, in comparison, can carry 90 or more missiles in its VLS.
Toward the end of September 2018, a Chinese Luyang-class destroyer challenged a US destroyer, the USS Decatur, to a showdown in the South China Sea during a routine freedom-of-navigation operation. The Chinese vessel is said to have nearly collided with the American warship.
Type 055 Renhai-class cruisers
While China designates these vessels as destroyers, the US classifies them as cruisers, due to their large size and role as multi-mission surface combatants. This ship is expected to serve a similar purpose to that of America’s Ticonderoga-class cruisers.
This ship, which began sea trials in August 2018, is armed with 112 vertical launch cells with the ability to fire HHQ-9 surface-to-air missiles, YJ-18 anti-ship cruise missiles, and CJ-10 land-attack cruise missiles.
The main gun is a H/PJ-38 130 mm gun, but there are reports that this vessel could eventually be equipped with a railgun.
Type 056 Jingdao corvettes
Chinese corvettes, like the newer PLAN frigates, feature improved anti-submarine warfare capabilities that could be advantageous to the carrier task force, although it’s unclear if China would actually incorporate these ships into a future carrier group, especially considering that the Type 054 frigates can provide the same capabilities.
“What the frigates and the corvettes have are variable-depth sonars, an active sonar operating at a lower frequency and on a cable that can be lowered down into the water below the [sonic] layer to actually find submarines,” Clark explained. “I think the Chinese would deploy a Jiangkai frigate or [Type 056] Jingdao corvette with the task force primarily for [anti-submarine warfare].”
These ships would play a lesser role in air defense, focusing instead on defending the task force from threats lurking beneath the surface of the sea.

Additional naval and support vessels
In waters near China, the need for support ships is limited. China can rely on its commercial shipping fleet, as well as various outposts and ports, but at greater distances, the task force will require support ships.
“I would anticipate the carrier task force is going to include an oiler to support them, and that oiler would be what goes ashore in these different bases along the Indian Ocean to receive supplies and fuel and take that out to the carrier task force,” Clark told Business Insider.
“Normally, when the Chinese deploy, such as when they deployed destroyers and frigates for counter-piracy operations in the Gulf of Aden, they’ve generally deployed two combatant ships and a support ship. They always have an oiler that goes with these ships.”

The Army plans to fly its Vietnam-era workhorse CH-47 Chinook cargo helicopter for 100 years by continuously upgrading the platform through a series of ongoing technological adjustments designed to improve lift, weight, avionics and cargo handling, among other things.
The Army goal is to allow the helicopter, which was first produced in the early 1960s, to serve all the way into the 2060s – allowing the aircraft service life to span an entire century.
“Our primary goal is maintaining the CH-47F’s relevance to the warfighter,” Lt. Col. Ricard Bratt said in a special statement to Scout Warrior.
The latest model, called the Chinook F helicopter, represents the latest iteration of technological advancement in what is a long and distinguished history for the workhorse cargo aircraft, often tasked with delivering food, troops and supplies at high altitudes in mountainous Afghan terrain.
Able to travel at speeds up to 170 knots, the Chinook has a range of 400 nautical miles and can reach altitudes greater than 18,000-feet. Its high-altitude performance capability has been a substantial enabling factor in the mountainous regions of Afghanistan.
The aircraft is 52-feet long, 18-feet high and able to take off with 50,000 pounds. The helicopter can fly with a loaded weight of 26,000 pounds. In addition, the aircraft can mount at least three machine guns; one from each window and another from the back cargo opening.
The Chinook F is in the process of receiving a number of enhancements to its digital cockpit called the Common Avionics Architecture System, or CAAS, such improved avionics, digital displays, Line Replacement Units, navigational technology, multi-mode radios, software and emerging systems referred to as pilot-vehicle interface. Pilot-vehicle interface involves improved computing technology where faster processor and new software are able to better organize and display information to the crew, allowing them to make informed decisions faster.
By 2018, the Army plans to have a pure fleet of 473 F-model Chinooks. By 2021, the Army plans to field a new “Block 2” upgraded Chinook F which will increase the aircraft’s ability to function in what’s called “high-hot” conditions of 6,000 feet/95-degrees Fahrenheit where lower air pressure makes it more difficult to operate and maneuver a helicopter.
The Block 2 Chinook will also be engineered to accommodate a larger take-off maximum weight of 54,000 pounds, allowing it to sling-load the Army’s new Joint Light Tactical Vehicle underneath. This provides the Army with what it calls a “mounted maneuver” capability wherein it can reposition vehicles and other key combat-relevant assets around the battlefield in a tactically-significant manner without need to drive on roads. This will be particularly helpful in places such as Afghanistan where mountainous terrain and lacking infrastructure can make combat necessary movements much more challenged.
The Chinook F is also in the process of getting new rotorblades engineered with composites and other materials designed to give the helicopter an additional 1,500 pounds of lift capability, Army officials explained.
Another key upgrade to the helicopter is a technology called Cargo-On/Off-Loading-System, or COOLS, which places rollers on the floor of the airframe designed to quickly on and off-load pallets of equipment and supplies. This technology also has the added benefit of increasing ballistic protection on the helicopter by better protecting it from small arms fire.
“The COOLS system has been added to the current production configuration and continues to be retrofitted to the existing F fleet. We have completed approximately 50-percent of the retrofit efforts. Since its fielding we made very minor design changes to improve maintainability.
The helicopter will also get improved gun-mounts and crew chief seating, along with a new vibration control system.
“We are finalizing design efforts on an improved vibration control system that, in testing, has produced significant reduction in vibration levels in the cockpit area,” Bratt said.
The F-model includes an automated flight system enabling the aircraft to fly and avoid obstacles in the event that a pilot is injured.
Additional adjustments include the use of a more monolithic airframe engineered to replace many of the rivets build into the aircraft, Army officials said.
“The program is looking at some significant airframe improvements like incorporating the nose and aft sections of the MH-47G (Special Operations Variant) on to the CH-47F. In addition, the program office has conducted an in depth structural analysis with the intent of setting the stage for increased growth capacity of the airframe for future upgrades,” Bratt said.
The CH-47 F program is also planning to add Conditioned-Based Maintenance to the aircraft – small, portable diagnostic devices, which enable aircraft engineers to better predict maintenance needs and potential mechanical failures, service officials said.
The CIRCM system is an improved, lighter-weight version of Advanced Threat Infrared Countermeasures, called ATIRCM, — a high-tech laser jammer that is able to thwart guided-missile attacks on helicopters by using an infrared sensor designed to track an approaching missile. The system fires a multiband heat laser to intercept the missile and throw it off course,
ATIRCM has been fielded now on helicopters over Iraq and Afghanistan. CIRCM, its replacement, lowers the weight of the system and therefore brings with it the opportunity to deploy this kind of laser counter-measure across a wider portion of the fleet.
Chinooks are also equipped with a combat-proven protective technology called Common Missile Warning System, or CMWS; this uses an ultraviolet sensor to locate approaching enemy fire before sending out a flare to divert the incoming fire from its course.
Finally, over the years there have been several efforts to engineer a small-arms detection system designed to locate the source of incoming enemy small-arms fire to better protect the aircraft and crew.
