The Pentagon is about to realize its dream of having a drone warship to hunt foreign stealth submarines.
Meet the ACTUV (Antisubmarine warfare Continuous Trail Unmanned Vessel) — a crewless,140-ton, 132-foot-long robotic ship unveiled in Portland’s Willamette River on Thursday.
“This is a big, big, deal,” Deputy Secretary of Defense Robert Work said.
“It looks like a Klingon Bird of Prey,” he added, admiring the vessel’s narrow bow.
“It’s extremely inexpensive compared to a manned system and it takes men and service women out of harms way. So why wouldn’t we want to do this?”
The ACTUV, pronounced “active,” costs $15,000 to $20,000 a day to operate, according to the Department of Defense. It was conceived in 2010 by Darpa, the Pentagon’s developmental wing responsible for testing emerging military technologies.
And those expenses are chump change compared with the operating costs of an aircraft carrier or submarine.
Staffing the ACTUV costs an estimated $684,900 a day.
“You can afford to use it in ways or think about using it in ways that would be too dangerous for a manned vessel,” Scott Littlefield, the ACTUV’s program manager, told Business Insider. “Like taking it into a minefield or taking it within range of somebody else’s weapons.”
“I don’t think we’ll ever get away from sailors on big ships,” he added, “but I could imagine a future in which we have a mixture of manned and unmanned systems working together.”
In short, ACTUV advances the US’s robotic-warfare abilities by supplementing the Navy’s manned fleet.
‘These will be everywhere’
The ACTUV’s completion comes as Russia and China, near-peer adversaries to the US, expand and update their navies.
According to NATO Vice Adm. Clive Johnstone, there is now more reported activity from Russian submarines in the North Atlantic than at any time since the Cold War. At the same time, China claims the majority of land in one of the most disputed areas on the planet: the South China Sea, which is home to $5 trillion in annual global trade.
To that end, the tit for tat over crumbs of territory in the South China Sea isn’t for nothing.
“This will operate wherever the United States Navy operates,” Work told Business Insider. “It can operate in the South China Sea. It can operate in the Baltic Sea. It can operate in the Persian Gulf. And it can operate in the middle of the Atlantic or the middle of the Pacific.”
“These will be everywhere,” he said.
The ACTUV’s sophisticated sonar system allows the unmanned vessel to hunt submarines, detect torpedoes, evaluate threats, and avoid small objects at sea — all while traversing the ocean at a top speed of 27 knots, or 31 mph.
This animation from Darpa depicts how ACTUV will hunt targets at sea:
While at sea, ACTUV will communicate information back to a military control center as well as to nearby Navy vessels and aircraft.
“There is no reason to be afraid of a ship like this,” Work said. “This is a ship that’s going to do what we tell it and nothing more.”
“The US military doesn’t really have the luxury of picking where it has to go, and the fact that the Navy has to be in all of those environments, that is what national security is all about, being able to do all of that,” Dr. Arati Prabhakar, the director of Darpa, told Business Insider.
Stand by for more testing
While ACTUV has already passed a few preliminary tests, the vessel must still undergo another two years of open-water trials with the Navy.
The Navy is slated to begin those tests in the summer 2016, in waters off San Diego.
If all goes well, the Navy hopes the vessel enters service by 2018.
From fighting pirates in the First Barbary War of 1801 to seizing the Kandahar International Airport in 2001 and beyond, Marine Corps infantrymen have been fighting and winning our nation’s battles for more than 200 years.
Known as “grunts,” infantrymen receive specialized training in weapons, tactics, and communications that make them effective in combat. And while many things have changed for grunts over time, they continue to carry on the legacy that was forged from the “small wars” to the “Frozen Chosin” to the jungles of Vietnam.
After more than a decade of war following the 9/11 attacks, many grunts have deployed to combat …
… In Iraq, where they earned their place in history at Nasiriyah, Najaf, and Fallujah (shown here), and many others.
While others deployed to Afghanistan, into the deadly Korengal Valley …
… Or more recently to Marjah, in Helmand Province.
But before infantrymen join their units, they need to complete initial training. For enlisted Marines, that means going to the School of Infantry, either at Camp Pendleton, California or Camp Geiger, North Carolina.
For officers, their training at Infantry Officer Course in Quantico, Va. involves both tactics and weapons, along with a more intense focus on how to lead an infantry platoon.
While most enlisted grunts become 0311 riflemen, others receive more specialized training, like 0331 machine-gunners, which learn the M240 machine gun (shown here), the MK19 grenade launcher, and the M2 .50 cal.
0341 Mortarmen learn how to operate the 60 mm (shown below) and 81 mm mortar systems, which help riflemen with indirect fire support when they need a little bit more firepower.
0351 Assaultmen learn basic demolitions, breaching, and become experts in destroying bad guys with the SMAW rocket system. The Shoulder-launched Multipurpose Assault Weapon (SMAW) is shown below.
Packing even more punch that’s usually vehicle-mounted, 0352 Anti-tank missilemen learn their primary M41 SABER (below) heavy anti-tank weapon and the Javelin, a medium anti-tank weapon.
Some more experienced infantrymen go into specialized fields, such as Reconnaissance or snipers (below).
Always present is a focus on mission accomplishment, and to “keep their honor clean” — to preserve the legacy of the Corps …
… That grunts are proud of. Always remembering heroics from the Chosin Reservoir Marines in Korea …
… To those who fought in Vietnam jungles, or the storied battles of Hue and Khe Sanh.
Since Vietnam, grunts have been repeatedly been called upon for minor and major engagements, such as Operation Desert Storm in 1991 and Operation United Shield in Somalia in 1995 (below).
The AC-130 just got its signature weapon back – and many in the public may not have known it was gone.
According to a report by Strategypage.com, the decision ends a 12-year hiatus on the powerful cannon, which has been used on versions of the Spectre gunship since 1972 – along with two 20mm Vulcan cannon and a 40mm Bofors anti-aircraft gun in the AC-130H. The AC-130U replaces the two 20mm guns with the 25mm GAU-12 used on the AV-8B Harrier.
The decision had been made to halt use of the 105mm gun in favor of missiles like the AGM-114 Hellfire and AGM-176 Griffin as well as the GBU-39 Small Diameter Bomb. The problem was, the need for guns didn’t go away. The Air Force started out by adding the 30mm Bushmaster II chain gun. This helped out, especially when troops were in close contact or there was a need to avoid collateral damage.
The gun’s rounds were also a lot cheaper than the missiles – even though the guns are only really useful at night.
The “boots on the ground” and the crews, though, kept making the case to bring the 105mm gun back. So, the Air Force tested a new mount for the 105mm gun. While previous incarnations of the AC-130 had the gun mounted to the side, now the gun will be fired from the rear of the plane.
While this puts an end to the famous pylon turn, it also means the AC-130 can hold twice as many 105mm howitzer rounds as it used to.
Testing of the new mount was finished in 2017, and will go on the new AC-130J Ghostrider, which will replace older AC-130H, AC-130U, and AC-130W aircraft by 2021.
Billionaire Paul Allen is known for founding Microsoft alongside Bill Gates, but after the events of the past week, he’ll also be known for helping to find an American warship missing since the end of World War II.
That vessel is none other than the storied USS Indianapolis, a Portland-class heavy cruiser which served the Navy for just under 15 years before being torpedoed on its way to Okinawa in July 1945.
The wreckage of the Indianapolis was discovered in the Philippine Sea, where it was lost upon completing a top secret mission to deliver parts for the “Little Boy” atomic bomb that would be dropped on Hiroshima. On its homecoming voyage, the cruiser was attacked by a Japanese submarine, caught completely unawares.
At the time of its loss, the Indianapolis was, for all intents and purposes, a “ghost.” Due to the secrecy of its mission to run nuclear weapon components to the Northern Mariana Islands, it was left out of rosters and no return or deployment was scheduled on paper.
Thus, its whereabouts of the ship where wholly unknown to all but a handful of ranking officials and officers outside the vessel’s crew.
It sank rapidly in deep shark-infested waters, taking hundreds of its crew with it before they could escape the sinking ship. The surviving crew were left adrift at sea without rations or enough lifeboats to hold them. Further complicating matters was the fact that no Allied vessel operating in the area received the ship’s frantic distress signals, meaning that help was definitely not on its way.
The survivors were picked up four days later, entirely by luck. A Ventura patrol aircraft on a routine surveillance flight happened upon clumps of the sailors floating around the Philippine Sea, with no ship in sight. Of the 1196 crew aboard the cruiser, only 321 were pulled out of the water, four of whom would die soon afterward.
Exposure to the elements, starvation and dehydration were some of the primary causes of death for the survivors adrift at sea, as were shark attacks. In fact, rescue pilots were so desperate to get sailors out of the water upon seeing shark attacks happening in real time, they ordered the survivors to be strapped to the wings of their aircraft with parachute cord once the cabin was filled to capacity.
Over seven decades after the Indianapolis went missing, Paul Allen’s research vessel, dubbed the “Petrel,” found the lost ship in 18,000 feet of water, resting silently on the ocean floor. The search has been years in the making, and was ultimately successful thanks to advances in underwater remote detection technology.
This isn’t the first lost warship found by Allen’s team. In 2015, they were also responsible for discovering the Japanese battleship Musashi — one of the largest battleships ever built — sunk during the Battle of Leyte Gulf.
The Indianapolis is officially still considered property of the U.S. Navy and will not be disturbed as it is the final resting place for hundreds of its deceased crew. Its location will henceforth only be known to Allen’s search team and the Navy.

When demonstrators in Springfield, Massachusetts marched to protest against heavy-handed law enforcement in the wake of George Floyd’s death it was entirely peaceful. No rocks were thrown at the police, no cars were turned over and no one was arrested in the state’s third largest city.
“The citizens of Springfield have a good working relationship with the cops,” said ArmySpecial Forces veteran and retired Massachusetts State Trooper Michael Cutone.
And he should know — he can take at least some of the credit for reworking the entire relationship.

Cutone split his time between the Army Guard and the police force, gathering decades of experience along the way. Eventually he started to see where lessons learned in his military career could apply to the toughest streets of Massachusetts.
“I was in the Guard, so when I got active duty orders, I would put on the green hat,” Cutone says. “I’d be gone six months, a year, then I’d be back in my trooper uniform. It was two different worlds but I loved both of them.”
Swapping between jobs kept him in touch with both the fundamentals of counterinsurgency overseas and the hard work of policing an area stateside. And it led him to wonder: what if he paired the best of both methods into a program for home?
In a time where calls to “defund the police” are growing louder, Cutone’s method of police work is now getting more funding from state and federal lawmakers. It’s called C3 Policing and it doesn’t take the police out of the community, it puts the needs of a community first.
“Community members are your greatest resource,” Cutone says. “In the Army, you don’t survive that well if you’re embedded in a hostile community, so you go win over the local population.”

If Cutone’s choice of words sounds familiar to Iraq and Afghanistan veterans, that shouldn’t be a surprise. “C3” means Counter Criminal Continuum and it’s basically the application of the Army Special Forces’ counterinsurgency tactics used in the Global War on Terror to violent crime and gang activity in American cities.
In 2009 the crime rate in Springfield was three times the rate in the State of Massachusetts as a whole.
“In the north end of the city, you hand open-air drug selling, gang members carrying SKS rifles out in the open and it culminated in three shooting and two murders in a week,” Cutone says.
Cutone asked his State Police sergeant if he could do a dismounted patrol — to walk around the streets 12th worst city in America in his State Trooper uniform. It was unheard of. Somehow, his sergeant agreed.
He began walking the streets, talking to people, buying a cup of coffee here, a pastry there. It dawned on Cutone that maybe law enforcement is approaching street crime in the wrong way. So he continued to walk the streets, engaging the population the way Army Special Forces taught him.
He went to community meetings to build legitimacy within the populace and eventually approached the city’s deputy police chief with his background and ideas. When the chief agreed to hear him out, Cutone wrote up an entire action plan for a small community in the North end of the city, using the eight building blocks taught by the Army.
Among these were “work by, with and through the local population” and “Detect, degrade, disrupt and dismantle criminal activity” — counterinsurgency maxims proven time and again overseas. Citizens began to meet police officers and interact with them. Eventually the local police force established a C3 Department and hand-picked C3 officers to begin to integrate themselves into the fabric of the community.
After retiring from both the Army and Massachusetts State Police in 2020, Cutone, with fellow State Trooper and Special Forces soldier Thomas Sarrouf, co-founded The Trinity Project, a police engagement consultancy and training company that trains officers in C3 Policing, using counterinsurgency to take back U.S. streets..
While “counterinsurgency” may bring to mind images of soldiers kicking in doors and raiding houses, Cutone said C3 is about building legitimacy through community partnerships using 8 core principles developed through the counterinsurgency techniques taught to American Special Forces:
Legitimacy is crucial to achieving our goals
You must understand the environment (the ground truth)
Unity of effort is essential
Intelligence drives operations
Prepare for a long-term commitment
Local factors are primary
Security under the rule of law
Gangs and drug dealers must be separated from their cause and support
“When you call the cops to come fix a problem, that’s just a transactional relationship,” Cutone says. “It’s not transformative. We are starting with a message to counter the gang’s message, offer services and create pressure points on these gangs to make it impossible to operate.”
The end result is transformational. Since Cutone began his style of policing, the annual crime rate of Springfield has decreased 6% every year. While the city is still not quite the bastion of law and order, things are beginning to turn around.
Some of the proof is seen outside the raw data. For example, more outside investment is beginning to come into the area. Buildings are no longer left vacant, businesses are coming in and drug dealers are no longer active in the open. C3 operations are even expanding to the rest of the city.
Cutone and his staff at the Trinity Project are ready to bring community engagement through C3 Policing to any city ready to think outside the box.
Two Russian military planes loaded with troops landed in Venezuela amid an escalating national crisis in the country, according to a Mar. 24, 2019, Reuters report. The planes departed from a Russian military airport and landed in Caracas just months after the two countries conducted military exercises in Venezuela.
The exercises also included troops from Cuba and China and were conducted along the Venezuelan border with Colombia. The planes were filled with at least 100 Russian troops that some say are a message to the Trump Administration, but will likely be helping the Venezuelan military settle the crisis there.
One of the planes carried the troops while another brought tons of military supplies and equipment. Venezuela’s military is the critical component to holding power there. President Nicolas Maduro maintains a tenuous grip on power because of the military, along with armed groups of militiamen whose role is to keep civilians in line. Those militias can be seen primarily along the Venezuelan border and are being used to keep American aid out of the country.
Challenging Maduro’s legitimacy is opposition leader Juan Guaido, who declared himself the legitimate President of Venezuela, with the backing of the United States. At least 50 other countries have recognized Guaido’s claim to power.
While the Chinese interest in Venezuela is primarily seen as a financial one – it has a lot invested in Venezuela’s neglected oil sector – Russian interest is believed to be an attempted check on American interventionism worldwide. Russian President Vladimir Putin may even establish a permanent Russian military presence in the country as a way to show the United States it means business.
Another indication that Russia is serious about bolstering the Maduro regime is that the planes allegedly carried Russian General Vasily Tonkoshkurov, the Chief of Staff of the Russian ground forces, with the rest of the Russian troops.
The United States criticized the move as Russian interference in the region. The planes were sighted at the airport in Caracas by a local journalist, who checked the planes against a flight tracking website. The site confirmed the Ilyushin IL-62 passenger jet and an Antonov AN-124 cargo plane departed Russia for Venezuela, after a brief stop in Syria.
Both Russia and Venezuela have not yet commented on what the troops will be doing there.
IWI US Inc.’s new Tavor TS12 semi-auto shotgun was definitely the most radical-looking weapon design at SHOT Show 2018 Range Day.
This new 12-gauge design is the company’s first foray into the tactical shotgun market and looks like it would be right at home on the set of the sci-fi classic, Starship Troopers.
I know many KitUp! readers are not fans of the bullpup design, but I have to say it was pretty nice to shoot.
The gas-regulated, semi-auto shotgun feeds from one of three rotating magazine tubes, each capable of holding four three-inch shotgun shells or five two-inch shotgun shells, for a total potential magazine capacity of 15 +1 rounds.
We were only able to load two shells in each tube because of safety rules at range day, so I didn’t get a feel for how much buckshot the TS12 is capable of sending down range.
It measures 28.34-inches overall and weighs eight pounds. The TS12 is bulky-looking, especially when you compare it to standard semi-auto and pump shotguns.
The Navy marked a first earlier this year when a woman completed Navy SEAL officer assessment and selection, Military.com has learned.
At the quarterly meeting of the Defense Advisory Committee on Women in the Services in December, a Navy official disclosed that the woman had reached the end of the physically and mentally demanding two-week SOAS process in September. Ultimately, however, she was not selected for a SEAL contract, officials said.
While the military formally opened SEAL billets — and all other previously closed jobs — to women in 2016, no woman has yet made it to the infamous 24-week Basic Underwater Demolition/SEAL (BUD/S) training to date. If the woman had been selected for a SEAL contract at the end of SOAS, she would have been the first to reach BUD/S.
Capt. Tamara Lawrence, a spokeswoman for Naval Special Warfare, said the candidate had not listed the SEALs as her top-choice warfighting community. She was awarded placement in her top choice, Lawrence said.

“We do not discuss details of a candidate’s non-selection so it does not interfere with their successful service in other warfighter communities,” she said.
Candidates for SOAS are taken from college Reserve Officer Training Corps programs, service academies, and the Navy’s Officer Candidate School, all prior to getting their first Navy contract. Lawrence declined to specify which pathway the recent female candidate had taken out of concern that doing so would reveal her identity.
Lt. Grace Olechowski, force integration officer with Naval Special Warfare Command, said five women had been invited to participate in SOAS since the pipeline was opened to women. Three had entered SOAS to date, but only one had completed assessment and selection.
Military.com broke the news in 2017 that a first female student had entered SOAS — an ROTC student at a U.S. college. She ultimately exited the process before reaching the selection panel, however.
Lawrence said the SEAL officer selection process is candidate-neutral, meaning the selection board does not know the gender or other personal information of the candidates.

“Selection is based on the candidate’s scores during the two-week SOAS assessment,” she said. “This process ensures every candidate has a fair and equal chance based on Naval Special Warfare standards.”
It’s also possible that not listing the SEALs as a primary career choice would factor against a candidate in the selection process.
The selection panel is made up of senior SEAL officers, Lawrence said, who use SOAS assessment data along with resume information to select “the most competitive candidates.”
Roughly 180 candidates are selected every year to attend SEAL officer assessment and selection, she said; on average, the top 85 candidates are chosen to continue on to SEAL training. There are four two-week SOAS blocks held every year.
While SOAS precedes the award of a final SEAL contract, it is not for the faint of heart. It was previously called “mini-BUD/S” in a nod to its grueling and rigorous nature.
“Physical stress and sleep deprivation are applied to reveal authentic character traits,” the Navy says on its official Naval Special Warfare recruiting site. “Performance and interview data on every candidate is meticulously documented and presented to the NSW Selection Panel.”

DARPA is looking for people with innovative ideas to participate in its “swarm sprint” exercises. The project would inform tactics and technologies for large groups of unmanned air and ground robots in certain environments.
The OFFensive Swarm-Enabled Tactics (OFFSET) program envisions future, small-unit infantry forces using small, unmanned aircraft systems and/or small, unmanned ground systems in swarms of 250 robots or more to accomplish diverse missions in complex urban environments. By leveraging and combining emerging technologies in swarm autonomy and human-swarm teaming, the program seeks to enable rapid development and deployment of breakthrough capabilities to the field.
Roughly every six months, DARPA plans to solicit proposals from potential sprinters, with each swarm sprint focusing on one of five thrust areas:
Here’s more about the project:
DARPA is awarding Phase 1 contracts to teams led by Raytheon BBN Technologies and the Northrop Grumman Corporation. Each team will serve as a swarm systems integrator tasked with designing, developing, and deploying an open architecture for swarm technologies in physical and virtual environments. Each system would include an extensible, game-based architecture to enable design and integration of swarm tactics, a swarm tactics exchange to foster community interaction, immersive interfaces for collaboration among teams of humans and swarm systems, and a physical testbed to validate developed capabilities.
Participants for the first core sprint are needed now. The focus of this effort is the generation of swarm tactics for a mixed swarm of 50 air and ground robots to isolate an urban objective within an area of two square city blocks over a mission duration of 15 to 30 minutes. Visit DARPA to learn about where to submit your proposal.
Sun Tzu advised in The Art of War, “When the enemy occupies high ground, do not confront him.”
This is why, since the advent of flight, all battlefield commanders have sought to control the airspace above the battlefield – the “ground” above the high ground.
Control of the airspace grants its occupant a clearer view of an enemy’s movements, better communications with friendly forces and the freedom to move quickly and unpredictably to attack downhill well behind the enemy’s front lines.
Forces on land, at sea and in the air all reap the advantages of the establishment of air superiority – the keystone to victories from World War II to Operation Iraqi Freedom. Just as important, occupying that high ground denies those same advantages to the enemy.
Research into lasers may offer advancement in propulsion technology to get us into deep space and beyond for a fraction of the cost. The geniuses at the Air Force Research Laboratory are developing multiple ways to utilize laser power to enhance weapons, mining in space and electrolyze water.
In peacetime, maintaining air superiority provides a deterrent to those potential adversaries who heed the warning of Sun Tzu.
That is why the Air Force and its researchers are constantly looking far beyond the horizon of the current battlefield to develop new technologies enabling access to the highest ground possible – space.
Even before the Soviet Union successfully launched the first satellite, Sputnik, into orbit in October 1957, the United States was developing its own top-secret satellites to provide intelligence, surveillance and reconnaissance (ISR) of potential adversaries – Project Corona.
While Sputnik was little more than a beeping aluminum ball orbiting the Earth, it was an undeniable Soviet flag planted on the global high ground. The U.S. government knew that ceding that high ground greatly increased the chances of defeat should the Cold War with the Soviet Union turn hot.
Vice-President Lyndon Johnson, who oversaw the fledgling National Aeronautics and Space Administration (NASA), firmly acknowledged the national security benefits of advancing the peaceful exploration of space in 1963.
“I, for one, don’t want to go to bed by the light of a Communist moon,” said Johnson.
To this day the U.S. Air Force has remained at the forefront of pushing farther into space, from launching communications and Global Positioning System (GPS) satellites to providing astronaut Airmen who first ventured into Earth orbit during Project Mercury, walked on the Moon during Project Apollo to Col. Jack D. Fischer currently aboard the International Space Station.
It is a legacy that surrounds and drives Dr. Wellesley Pereira, a senior research physical scientist with the Air Force Research Lab’s (AFRL) Space Vehicles Directorate at Kirtland Air Force Base, New Mexico.
The very site at which Pereira conducts his research is named for an Airman who led the charge to put an American on the Moon.
The Phillips Research Site is named for Air Force Gen. Samuel Phillips, who served as Director of NASA’s Apollo manned lunar landing program from 1964 to 1969. That program culminated in the first humans, Neil Armstrong and then Air Force Lt. Col. Edwin “Buzz” Aldrin, landing on the moon in 1969 as Air Force Lt. Col. Michael Collins piloted the Apollo 11 Command Module overhead. It was the kind of aggressive manned exploration of space that Pereira would not only like to see continue, but accelerate.
“The Air Force and its Airmen are seen as trendsetters, as in the case with GPS, benefiting all humanity, or with technologically-inspired precision airdrops from 30,000 feet of lifesaving supplies during humanitarian crises,” said Pereira. “In doing this the Air Force establishes itself as a global power in which it does not cede higher ground to anyone… It pays dividends to be at the leading edge of that technology as opposed to playing catch up all the time. The Air Force can really send a very positive message by being that trendsetter in space.”
Pereira is currently researching infrared physics and hyper-spectral imaging as a means to provide ISR data over a wide range of light not visible to the human eye.
“We simulate cloud scenes viewed from spacecraft,” said Pereira. ” (Examining) all the aspects that affect an image from space like the artifacts caused by movement in the space platform; trying to process signals, trying to process information. We try to simulate these things in our lab just to understand spacecraft processes and how we can deal with this in post-processing.”
Pereira’s current position at AFRL as a research scientist coupled with a background in astronomy, physics and space research gives him the opportunity to think deeply about space and human space flight.
“As a research scientist, I’ve been involved in building payloads for the Air Force on satellites,” said Pereira. “This has led me to think about satellites in general; launch, orbits, moving in and out of orbits, the mechanics of orbits and the optimization of orbits.”
Those contemplations have led Pereira to envision an Air Force of the future that will propel its assets and Airmen to increasingly higher ground in space in a cost-effective way that combines technology old and new – sails and lasers.
“Up until now, we’ve been using chemical propulsion to get into space. Chemical propulsion is limited in what it can do for us in the future. We cannot go very far. We have to take resources from the Earth into space, which is a big issue considering we only can carry so much mass, we only have so much power, and so on. It is limited by chemical bond, but it is also limited by size, weight, power,” said Pereira.
The concept of solar sails has existed for quite a while. A solar sail uses photons, or energy from the sun to propel a spacecraft. Photons have energy and momentum. That energy transfers to a sail upon impact, pushing the sail and spacecraft to which it is attached, farther into space, according to Pereira.
“The Japanese have already proven that we can fly stuff with a solar sail. In 2010, they sent up an experiment called IKAROS, Interplanetary Kite-raft Accelerated by Radiation Of the Sun. This was a very successful project,” said Pereira.
“In the same vein as solar sails, futurists have also thought about laser sails. I think this is an area where the Air Force can develop an ability for us to propel spacecraft farther using lasers, either in the form of laser arrays on Earth or taking a laser array and putting it on the moon, to propel spacecraft without the cost of lifting spacecraft and chemical propellant from the Earth’s surface.”
In the near future, Pereira sees this method as a cost-effective way the Air Force can lift satellites into higher Earth orbit.
“You have spacecraft go into orbits that are just about 300 to 600 kilometers above the Earth. We call those Low Earth Orbits or LEO. Likewise, you have orbits that could be about 36,000 to 40,000 kilometers above the Earth. We call them Geostationary Earth Orbits or GEO orbits. Many communications satellites, as well as, a few other satellites are in Geostationary orbit…the way of the future, would be to use laser based arrays, instead of chemical propulsion, to fire at a satellite’s sail to push it to a higher orbit,” said Pereira.
“Our goal is to try and minimize taking resources from earth to space. We can literally just launch a rocket using a catapult that could boost to about 100 meters per second and, once we get it to a certain altitude, we can have an array of lasers focus on the sail on the rocket, propel it out farther, whether it’s intended for a LEO orbit or whether it’s intended for a GEO orbit. As long as you can build material that can endure the laser energy without tearing, I think this is a far cheaper way to go and it could save the Air Force a lot of money.”
According to Pereira, developing this technology would naturally lead to the ability to propel spacecraft carrying Airmen farther into the solar system where they could establish self-sustaining outposts on ever higher ground.
“NASA’s Orion Multi-Purpose Crew Vehicle, the MPCV, is essentially a spacecraft designed to take astronauts farther than any human has ever gone before. One test flight concept is to visit an asteroid called 1999 AO10, in around 2025,” said Pereira. “This asteroid does not have a lot of gravity and not a lot of surface area, so rather than walking on the asteroid, the idea is for the spacecraft to connect itself to the asteroid, and for the astronauts to do spacewalks to mine materials, so that they can bring them back to Earth for analysis.”
Past and current Air Force research during manned space flight has led to increased understanding of human physiological response to microgravity and exposure to radiation, development of life support systems, nutritious food packaging, sophisticated positioning, navigation and timing software and systems that could one day enable Airmen to routinely fly to and mine asteroids and planetary moons for needed resources.
Pereira also sees Air Force cooperation with commercial companies developing space flight technologies as a benefit to both, from developing suborbital space planes, manned capsules and space waypoints, or “hotels”, to projects as ambitious as Breakthrough Starshot, a proposed mission to send a microchip all the way to Proxima B, an exo-planet orbiting the star Proxima Centauri, and transmit data back to Earth.
“They want to do this at about 20 percent of the speed of light, meaning it will take five times as long as it would take light to travel between the Earth and Proxima Centauri, approximately four light years away. So it could take only about 20 years for this chip to get to Proxima Centauri. Then if it beams images back at the speed of light, it would take another four years for that data to come back. In about 24 years, we would get data from Proxima Centauri, our nearest star,” said Pereira.
Pereira believes that the Air Force participating in such ventures into the space domain could lead to technologies that could send Airmen to the moons of outer planets in our solar system within a person’s lifetime, benefiting the human race and keeping the Air Force firmly atop the high ground.
“First and foremost, Airmen, as many times in the past, can serve in the capacity of professional astronauts: providing services in scouting and setting up breakthrough scientific missions, establishing colonies for repair and mining in order to reduce or avoid having to take materials from Earth to space…enabling safe pathways, providing in-flight maintenance, refueling crews, more effectively than machines might be able to do.”
“There are so many wonderful things about space that are so fascinating that we can explore and learn so much more if we just keep that aspect of space exploration going. We can achieve this by having our Airmen lead the way to an era of exploration enabled by human space flight.”
The US is accusing Iran of carrying out attacks on two tankers just outside the Strait of Hormuz, a critical waterway through which more than 30% of the world’s seaborne crude oil passes, and the US Navy has reportedly discovered an unexploded mine that may very well be evidence of Iran’s culpability in June 13, 2019’s attacks.
The USS Bainbridge, a US warship deployed to the Middle East, spotted a limpet mine on the side of one of the two tankers hit on June 13, 2019, CNN reported, citing a US defense official. Another defense official confirmed the discovery to Fox News, telling reporters that “it’s highly likely Iran is responsible.”
Secretary of State Mike Pompeo said June 13, 2019, that Iran was responsible for the attacks, an announcment that briefly spiked US West Texas Intermediate crude oil futures up to $52.88 per barrel, or 3.4% from the day’s start.
He did not provide specific evidence for the accusations but said US conclusions were “based on the level of expertise for the execution, and recent attacks on shipping, and the fact that no proxy group operating in the area has the resources and proficiency to act with such a high degree of sophistication.”
The limpet mine spotted by the US Navy was reportedly discovered on the Kokuka Courageous, one of two tankers targeted. Twenty-one sailors rescued from the damaged ship are aboard the USS Bainbridge, an Arleigh Burke-class guided-missile destroyer that was operating nearby and called in to assist.
A limpet mine is an explosive with a detonator that can be attached to the hull of a ship using magnets, and Iranian forces are believed to have used these weapons in an attack on four oil tankers off the coast of the United Arab Emirates in May. While the US has blamed Iran for the attacks, Tehran, Iran’s capital, has repeatedly denied any involvement.
The UAE determined an unnamed “state actor” was behind the tanker attacks and concluded “it was highly likely that limpet mines were deployed.”
There has been some debate about who was behind the latest attacks, with one official telling ABC News that “we’re not pointing to Iran, but we’re not ruling anything out at this time.” Another official asked the media outlet, “Who else could it be?”
U.S. Blames Iran for Tanker Attacks in Gulf of Oman
Iran used mines heavily during the Tanker Wars in the late 1980s.
Florida Sen. Marco Rubio, who may have been briefed on the situation, was quick to pin the blame on Iran’s Revolutionary Guard Corps, telling reporters: “I saw some press accounts today sort of saying it’s not clear who did it. Well, it wasn’t the Belgians. It wasn’t the Swiss. I mean, it was them. They’re the ones that did it. We’ve been warning about it.”
In early May 2019, the US began deploying military assets to the Middle East as a deterrence force in response to intelligence indicating that Iran was planning attacks on US interests. The US has so far sent a carrier strike group, a bomber task force, a missile-defense battery, and a number of other capabilities into the US Central Command area of responsibility.

Hours before the rise of the very star it will study, NASA’s Parker Solar Probe launched from Florida on Aug. 12, 2018, to begin its journey to the Sun, where it will undertake a landmark mission. The spacecraft will transmit its first science observations in December, beginning a revolution in our understanding of the star that makes life on Earth possible.
Roughly the size of a small car, the spacecraft lifted off at 3:31 a.m. EDT on a United Launch Alliance Delta IV Heavy rocket from Space Launch Complex-37 at Cape Canaveral Air Force Station. At 5:33 a.m., the mission operations manager reported that the spacecraft was healthy and operating normally.
The mission’s findings will help researchers improve their forecasts of space weather events, which have the potential to damage satellites and harm astronauts on orbit, disrupt radio communications and, at their most severe, overwhelm power grids.
“This mission truly marks humanity’s first visit to a star that will have implications not just here on Earth, but how we better understand our universe,” said Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate. “We’ve accomplished something that decades ago, lived solely in the realm of science fiction.”

During the first week of its journey, the spacecraft will deploy its high-gain antenna and magnetometer boom. It also will perform the first of a two-part deployment of its electric field antennas. Instrument testing will begin in early September 2018 and last approximately four weeks, after which Parker Solar Probe can begin science operations.
“Today’s launch was the culmination of six decades of scientific study and millions of hours of effort,” said project manager Andy Driesman, of the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland. “Now, Parker Solar Probe is operating normally and on its way to begin a seven-year mission of extreme science.”
Over the next two months, Parker Solar Probe will fly towards Venus, performing its first Venus gravity assist in early October 2018 – a maneuver a bit like a handbrake turn – that whips the spacecraft around the planet, using Venus’s gravity to trim the spacecraft’s orbit tighter around the Sun. This first flyby will place Parker Solar Probe in position in early November 2018 to fly as close as 15 million miles from the Sun – within the blazing solar atmosphere, known as the corona – closer than anything made by humanity has ever gone before.
Throughout its seven-year mission, Parker Solar Probe will make six more Venus flybys and 24 total passes by the Sun, journeying steadily closer to the Sun until it makes its closest approach at 3.8 million miles. At this point, the probe will be moving at roughly 430,000 miles per hour, setting the record for the fastest-moving object made by humanity.
Parker Solar Probe will set its sights on the corona to solve long-standing, foundational mysteries of our Sun. What is the secret of the scorching corona, which is more than 300 times hotter than the Sun’s surface, thousands of miles below? What drives the supersonic solar wind – the constant stream of solar material that blows through the entire solar system? And finally, what accelerates solar energetic particles, which can reach speeds up to more than half the speed of light as they rocket away from the Sun?

Scientists have sought these answers for more than 60 years, but the investigation requires sending a probe right through the unrelenting heat of the corona. Today, this is finally possible with cutting-edge thermal engineering advances that can protect the mission on its daring journey.
“Exploring the Sun’s corona with a spacecraft has been one of the hardest challenges for space exploration,” said Nicola Fox, project scientist at APL. “We’re finally going to be able to answer questions about the corona and solar wind raised by Gene Parker in 1958 – using a spacecraft that bears his name – and I can’t wait to find out what discoveries we make. The science will be remarkable.”
Parker Solar Probe carries four instrument suites designed to study magnetic fields, plasma and energetic particles, and capture images of the solar wind. The University of California, Berkeley, U.S. Naval Research Laboratory in Washington, University of Michigan in Ann Arbor, and Princeton University in New Jersey lead these investigations.
Parker Solar Probe is part of NASA’s Living with a Star program to explore aspects of the Sun-Earth system that directly affect life and society. The Living with a Star program is managed by the agency’s Goddard Space Flight Center in Greenbelt, Maryland, for NASA’s Science Mission Directorate in Washington. APL designed and built, and operates the spacecraft.
The mission is named for Eugene Parker, the physicist who first theorized the existence of the solar wind in 1958. It’s the first NASA mission to be named for a living researcher.
A plaque dedicating the mission to Parker was attached to the spacecraft in May 2018. It includes a quote from the renowned physicist – “Let’s see what lies ahead.” It also holds a memory card containing more than 1.1 million names submitted by the public to travel with the spacecraft to the Sun.
When ships deploy out to sea, it’s important they bring the fuel and spare parts they need. The ship’s crew also needs to be supplied. While food is often transferred to these ships, there’s also the pressing need for the crew to drink.
Although they’re surrounded by water, the ocean upon which these ships float isn’t exactly the best thing to drink. The National Oceanic and Atmospheric Administration points out that if you drink sea water, you get more dehydrated and, ultimately, dehydration kills people. Drinking seawater brings about other health problems that can cause problems on board ship, specifically the head.
It used to be that ships had to carry water that was safe for drinking. This made crossing oceans difficult to say the least. The sailing frigate USS Constitution (ex-IX 21), one of the original six frigates built for the United States Navy, had a crew of 450. Humans need to drink nearly a gallon of water a day, according to the Mayo Clinic, which, as you can imagine, meant carrying a lot of fresh water as cargo.
Well, today, making sure the sailors have plenty of fresh water for all their needs is much easier. The Navy can do this thanks to the Light Weight Purification System. It just takes one sailor to operate, and it can handle anything from sea water to fresh water. According to a Marine Corps document, this system can purify 75 gallons of water per hour.
The Navy, of course, has other systems that can handle larger amounts, but the Light Weight Purification System is very mobile, which becomes very useful for Marines on the front lines. Learn more about this system in the video below:
