This is not an idle thought. On March 26, 2010, the Pohang-class corvette ROKS Cheonan was torpedoed and sunk by a North Korean mini-sub firing a 21-inch torpedo. So, the concern is what one of these subs could do to a carrier.
Let’s look at what these subs are. The North Koreans have two front-line classes of mini-sub, according to the 16th Edition of Combat Fleets of the World. The Yono — the type of sub believed to have fired the torpedo that sank the Cheonan — is about 110 tons and carries two 21-inch torpedoes. The Sang-O is 295 tons and also has a pair of 21-inch torpedo tubes.
North Korea also has Romeo-class submarines, which have eight 21-inch torpedo tubes (six forward, two aft), with a total of 14 torpedoes. North Korea also has some mini-subs built to a Yugoslavian design with two 16-inch torpedoes, but those are believed to be in reserve.
That said, American aircraft carriers are very tough vessels. In World War II, the carriers USS Yorktown (CV 5) and USS Hornet (CV 8) took a lot of abuse before they sank. The carrier USS Franklin (CV 13) had one of the great survival stories of the war, despite horrific damage.
But today’s carrier are much larger.
In fact, the Russians designed the Oscar-class guided-missile submarine to kill America’s Nimitz-class carriers – and those have 24 SS-N-19 “Shipwreck” missiles, plus four 21-inch torpedo tubes and four 25.6-inch tubes meant to fire torpedoes with either massive conventional warheads or even nuclear ones.
This points to a North Korean sub being unable to sink a Nimitz-class carrier on its own.
But two torpedoes will still force a carrier to spend a long time in the body shop. And the escorts are more vulnerable as well.
A U.S. carrier could take a couple of hits and in a worst case scenario, she’d have to fly her air wing to shore bases.
The US Navy is currently testing a robotic ship that would be able to autonomously hunt enemy diesel submarines.
Originally conceived as a DARPA project, the Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV) is designed to hunt the next generation of nearly silent enemy diesel submarines.
Diesel submarines are quickly proliferating around the world due to their low cost. Russia recently announced that it has launched the world’s “quietest submarine.”
To accomplish its submarine-hunting mission, the ACTUV project is structured around three primary goals: the ability to outmatch diesel submarines in speed at significantly less cost than existing systems, the system’s ability to safely navigate the oceans in accordance with maritime law, and the ability to accurately track diesel submarines regardless of their location.
Tests of the ACTUV have been promising. Defense One reported in March that during six weeks of testing off the coast of Mississippi the ACTUV was capable of autonomously avoiding randomly moving vessels while navigating around natural obstacles.
The next major test for the ACTUV will be having the drone attempt to trail a submarine while other vessels attempt to block it.
Although diesel submarines are not capable of carrying out open ocean operations for as long or as quickly as nuclear submarines, diesel submarines still present the US with an asymmetric challenge. Significantly cheaper and more quiet-running than their nuclear counterparts, diesel subs can enable navies around the world to harass military and civilian transport along coastal routes.
The threat of diesel submarines could increase, as Franz-Stefan Gady notes at The Diplomat, as the next generation of these vessels will feature propulsion systems and lithium-ion batteries, making them even quieter and harder to detect.
The technical challenges are steep: “Picking up the quiet hum of a battery-powered, diesel-electric submarine in busy coastal waters is like trying to identify the sound of a single car engine in the din of a major city,” Rear Admiral Frank Drennan said in March 2015.
By creating the ACTUV, the US Navy will be able to more accurately track the proliferation of enemy diesel submarines. The transition to using drones for such missions will also ultimately save the Navy considerable resources and manpower.
“Instead of chasing down these submarines and trying to keep track of them with expensive nuclear powered-submarines, which is the way we do it now, we want to try and build this at significantly reduced cost,” DARPA program manager Ellison Urban said at a National Defense Associate Event in Virginia.
“It will be able to transit by itself across thousands of kilometers of ocean and it can deploy for months at a time. It can go out, find a diesel-electric submarine and just ping on it.”
Former Russian spy Sergei Skripal left the hospital in May 2018, after recovering from an assassination attempt. Skripal and his daughter were poisoned with a nerve agent at his home in Salisbury in March 2018, by Russian spies, British counter-terror authorities have said.
One creepy prospect for the Skripals is that the would-be assassins may still be in the UK, living undercover as normal people, Russian espionage experts say. It’s easy to smuggle people out of Britain. For those of us not in the espionage business, it seems surprising that the attackers would stay in the country rather than escape immediately.
But Russia probably left its agents in place for an extended period after the attack.
Madeira told Business Insider that if a sleeper agent was used in the attempt on Skripal’s life, he or she probably remained in Britain after the attack rather than trying to immediately escape back to Russia.
“Why leave someone here, at risk of detection, after such a high-profile attack?” he told Business Insider. “I can only think of two scenarios where that might happen:
“An actual ‘illegal’ with an existing, years-long ‘legend’ would attract attention by going missing all of a sudden – i.e. friends, co-workers or neighbours might report a missing person to police, who might then put two and two together and tie that person to the Skripal attack. Better to keep him/her in place, living a mundane life again, their role in this operation now concluded.”
“Someone who isn’t an ‘illegal’ in the strictest sense of the word, but for now having to stay in hiding in the UK until things settle down a bit. Perhaps with a new set of ID papers, s(he) can eventually look to exit the country via a quieter, lower-profile exit point.”
Obviously, we cannot know exactly what the operative did after the attack. The Mirror reported in April 2018, that one suspect has flown back to Russia. Earlier that month, the Mirror’s source speculated that the sleeper agent would still be in the UK, ready for another mission. “Unless it were an absolute emergency and the operative had to chance a ‘crash escape’, this exit point would normally be carefully picked based on e.g. the set of ID papers available, the person’s appearance and overall profile, history in the UK if checked by the Border Force, how tight border controls were assessed to be at that exit point, etc.,” Madeira told Business Insider.

Moscow first sent fighter jets to Syria in 2015 to help the Assad government, which is a large purchaser of Russian arms. In the first few months of 218, Russia and the Syrian regime have increased bombing runs in Idlib and Eastern Ghouta, killing, injuring and displacing thousands of civilians.
Here are the 11 kinds of military jets and planes Russia has in Syria now:
The Israeli satellite images showed two Su-57s at Hmeimim air base.
The Su-57 is Russia’s first fifth-generation stealth jet, but they are only fitted with the AL-41F1 engines, the same engine on the Su-35, and not the Izdelie-30 engine, which is still undergoing testing.
The satellite images from July showed 11 Su-24 Fencers, but that number might now be 10, since one Fencer crashed in October, killing both pilots.
The Su-24 is one of Russia’s older aircraft and will eventually be replaced by the Su-34, but it can still carry air-to-air and air-to-surface missiles, as well as laser-guided bombs.
The July satellite images showed three Su-25 Frogfoots.
The Frogfoot is another of Russia’s older attack aircraft. It’s designed to make low-flying attack runs and is comparable to the US’s legendary A-10 Warthog.
Su-25s had flown more than 1,600 sorties and dropped more than 6,000 bombs by March 2016, just six months after their arrival in Syria.
One Su-25 was also shot down by Syrian rebels and shot the pilot before he blew himself up with a grenade in early February 2017.
This photo, taken near the Hmeimim air base in 2015, shows an Su-25 carrying OFAB-250s, which are high-explosive fragmentation bombs.
This shows a Russian airmen fixing a RBK-500 cluster bomb to an Su-25 in Syria in 2015.
The satellite images from July showed three Su-27SM3 Flankers, which were first sent to Syria in November 2015.
The upgraded Flankers, which are versatile multirole fighters, were deployed to the war-torn country to provide escort for its other attack aircraft, among other tasks.
The satellite images from July 2017 showed four Su-30SMs.
The Su-30SM, a versatile multirole fighter that’s based off the Su-27, carries a variety of air-to-air and air-to-surface missiles and laser-guided bombs.
The July 2017 satellite images showed six Su-34 Fullbacks.
The Fullback, which first deployed to Syria in September 2015, was Russia’s most advanced fighter in the war-torn country for over a year.
It carries short-range R-73 and long-range radar-guided R-77 air-to-air missiles. It also carries Kh-59ME, Kh-31A, Kh-31P, Kh-29T, Kh-29L, and S-25LD air-to-ground missiles.
The picture shows a Russian airman checking a KAB-1500 cluster bomb on a Su-34 in Syria in 2015.
This shows Russian airmen installing precision-guided KAB-500s at the Hmeimim air base. One airman is removing the red cap that protects the sensor during storage and installation. The white ordnance is an air-to-air missile.
The video below shows a Fullback dropping one of its KAB-500s in Syria in 2015:
The July 2017 satellite images showed six Su-35S Flanker-E fighters.
The Flanker first deployed to Syria in January 2016 and is one of Russia’s most advanced fighters, able to hit targets on the ground and in the air without any air support.
The July 2017 satellite images showed one A-50U Mainstay.
The A-50U is basically a “giant flying data-processing center” used to detect and track “a number of aerial (fighter jets, bombers, ballistic and cruise missiles), ground (tank columns) and surface (above-water vessels) targets,” according to Sputnik, a Russian state-owned media outlet.
10. IL-20 “Coot”
The Coot “is equipped with a wide array of antennas, IR (Infrared) and Optical sensors, a SLAR (Side-Looking Airborne Radar) and satellite communication equipment for real-time data sharing,” according to The Aviationist.
It’s one of Russia’s most sophisticated spy planes.
11. An-24 “Coke”
The An-24 Coke is an older military cargo plane.
Below is one of the July 2017 satellite images, showing many of Russia’s fighters lined up.

Since 2015, Russian airstrikes in Syria have taken out many ISIS fighters — although their numbers are often exaggerated — but they have also killed thousands of civilians.
The Syrian Observatory for Human Rights reported that between September 2015 and March 2016 alone, Russian airstrikes had killed about 5,800 civilians.
Russia and the Syrian regime have increased bombing runs in Idlib and Eastern Ghouta, killing 290 civilians in one 48-hour period late February 2018.
“No words will do justice to the children killed, their mothers, their fathers and their loved ones,” the UN recently said in a statement. “Do those inflicting the suffering still have words to justify their barbaric acts?”
A number of monitoring groups have also accused Russia of deliberately targeting hospitals and civilians, but Moscow barely acknowledges the civilian deaths and often denies it.
The Pentagon is throwing $700 million at a rapidly progressing program to combat the threat of commercial drone use by the Islamic State, The New York Times reports.
The program has commissioned U.S. defense contractors to begin attempting to find solutions to the drone threat, including using lasers to shoot them out of the sky. The technology is in its infancy and has yet to yield any significant results. ISIS has pioneered the use of relatively cheap commercial drones as airborne improvised explosive devices, for surveillance, and propaganda purposes.
The Pentagon program comes as it increases the number of U.S. troops in Syria to assist training for the Syrian Democratic Forces in the fight against ISIS. The Pentagon reportedly worries that its bases could be vulnerable to ISIS drone attacks, and it sees the broader trend in warfare.
The terrorist group used some commercial drones to drop cheap IED’s on the Iraq Security Forces during the Battle for Mosul. ISIS announced the formation of a new drone warfare unit in January, whose sole purpose is to inflict “a new source of horror for the apostates.” The terrorist group said the new unit killed nearly 40 Iraqi soldiers in just one week.
The threat may not just be limited to the battlefield. Georgetown terrorism expert Dr. Bruce Hoffman recently warned that drone “swarms” could become a facet of western terrorist attacks. Hoffman outlined one such scenario, telling readers, “picture Paris on November 13, 2015 [the night when people were slaughtered at a rock concert and in sidewalk cafés] with drone attacks superimposed on top of it. Authorities would have been completely overwhelmed. This elevates our greatest fear, which is simultaneous urban attacks—now with swarming on top of them.”
As the coronavirus pandemic continues to uproot life around the world, it’s easy to feel, well, uneasy. After all, there are a lot of unknowns. But there are plenty of ways to arm yourself with proper information and feel a bit more grounded. Doctors, for instance, are all mandated to take state-mandated infection courses online. Available to the public, and free unless someone wants to take a test to pass, the courses offer a wealth of public information. While they are a bit of a slog to read (and nary an educational video in sight) they’re helpful for anyone who wants to know everything from if their bleach is strong enough to kill bacteria or how to put on gloves without covering them in germs.
So, which courses might be useful? One, administered by Access Continuing Education Inc., intended for doctors in New York State, and aptly (and drily) titled Infection Control: New York State Mandatory Training, contains a wealth of worthwhile information. The course isn’t like a typical virtual classroom — there are no teachers, no video sessions, and no mandated quizzes at the end. There are no hours required to finish the course and each ‘Element,’ a full-text article that reads about a page long, touches on a different process of how to limit transmission.
Is it an exciting read? No, but the pages are full of very, very important information, including hand washing technique, what the proper etiquette and technique is when coughing, and how to clean spills of bodily fluids. Other relevant information for parents within the text include what protective gear people can wear to limit transmission (including gloves, masks, and goggles) and how to put them on while also keeping them clean. The text also defines the different levels of sterilization and what recommended, medical grade sterilizers can be used and how to dilute bleach.
Now, a large chunk of the course does focus on safe usage of needles — which is not exactly relevant for parents and Coronavirus — but the text is free to read online for anyone who wants to be educated on best practices and how to stay safe. There’s a test at the end of the course, which does not need to be taken, obviously, as parents could just be reading this for their own information, but could be fun if you’re very, very bored.
The average parent won’t be using scalpels or lancets, but they can learn the differences between cleaning and disinfecting surfaces, learn how professionals limit potential exposure from patients when dealing with infectious diseases, and learn strategies for how to limit the spread of pathogens in the home and use those in their own spaces.
Knowledge, at a time like this, can be empowering. It can also be scary if that knowledge is not actionable. That’s why these courses are an excellent resource. They provide parents a sense of control of a situation over which no one has control. They can help parents do all that they can to help keep their families healthy. And that is what it will take to limit the spread of this disease: serious, educated action, social distancing, and disinfecting.
A former Army officer will spend his Independence Day Tuesday by competing in the renowned Nathan’s Famous International Hot Dog Eating Contest.
“Buffalo” Jim Reeves was one of 20 other competitors to earn a spot on the nationally televised gastronomic event. He made the cut by eating 23 hot dogs.
“There’s no big secret to competitive eating,” Reeves told the Army Times. “You try your hardest and you’re either good or you’re not. I happened to be good.”
Reeves turned from soldier to competitive eater in 2002 by competing in the National Buffalo Wing Festival, where he finished as a finalist. He joined the Army in 1990 after completing reserve officers’ training corps at Clarkson University. He later attended the Engineer Officers’ Basic Course at Fort Leonard Wood, Mo.
Reeves served as a a platoon leader, acting company commander, battalion personnel officer and civil engineering officer before leaving the Army in 1998. He now makes a living as a math and computer science teacher in New York.
The former engineering officer’s technique is simple: he downs two hot dogs at a time by separating the hot dogs from the buns and dipping the buns in water to help facilitate swallowing.
Reeves may be good, but he will have to be at his all-time best if he stands a chance at winning Tuesday’s contest. The world-famous Joey Chestnut won last year’s contest by consuming 70 hot dogs, setting a new world record. Odds makers put Chestnut at a distinct advantage to defend his title, known as “The Mustard Belt.” The winner is expected to consume 67.5 dogs, meaning that Reeves will have to triple his qualifying number to have a shot at victory.
The Senate Armed Services Committee has set aside millions for light attack aircraft, but this time not solely for the U.S. Air Force.
In its version of the fiscal 2019 budget markup, the committee announced in May 2018, it wants to give $100 million to the Marine Corps to procure light attack aircraft such as the AT-6 Wolverine to boost lower-cost aviation support. The version passed the committee with a vote of 25-2. It heads for a full Senate vote in coming weeks.
Is the Marine Corps ready for it? It’s unclear.
“The Marine Corps continues to monitor the Air Force-led Light Attack Experiment to procure a cost-effective, observation and attack (OA-X) air platform for employment in permissive environments, with the intent to employ such an asset as a joint force capability,” said Capt Christopher Harrison of the Office of Marine Corps Communication at the Pentagon.
“The SASC’s decision to authorize $100 million for a light attack platform is only reflected in a policy bill,” Harrison said in an email on June 1, 2018.
“Nothing has been appropriated to this program yet,” he said.
But some experts say investing in light attack, though not the stealthiest or best equipped aircraft category, is not an entirely improbable idea.
“I think there’s a strong case for the Marines, or the Air Force, or both, having a few dozen light attack planes, if only for joint training and even combat missions with allied militaries in much poorer nations,” Aboulafia told Military.com on May 30, 2018.
Lawmakers and a few Pentagon officials have made the case for light attack — especially in the context of the Air Force’s ongoing experiment with light attack platforms — saying the smaller planes could come in handy to offset the cost to taxpayers to put a few fifth-generation fighters in the air, sometimes in support of missions for which the advanced jets are far overqualified.
For example, Air Force Secretary Heather Wilson reiterated it is silly to use a stealth fighter like the F-22 Raptor to take on Taliban drug labs. In November, the Raptor made its combat debut in Afghanistan, targeting suspected narcotics facilities in the country with small-diameter bombs.”We should not be using an F-22 to destroy a narcotics factory,” Wilson said, echoing previous statements she has made on the topic.
Light attack aircraft in that role would be more sensible, she said.
For the correct mission set, light attack makes sense for any service, Aboulafia argued. But purchasing an entire fleet, he said, would be unjustifiable, since the aircraft’s warfighting capabilities are significantly limited, and best suited to low-risk missions and training with allies and partners.
“What kind of scenario would call for that? It postulates a giant failed state, or series of failed states, where the U.S. is compelled to intervene, and yet there’s absolutely no air-to-air and only a minimal ground-to-air threat,” Aboulafia said.

He added, “If there’s either of those, this type of plane is a great way to kill pilots. And if this giant, under-armed failed-state intervention doesn’t materialize, the military is stuck with hundreds of planes that have zero relevance to any other kind of strategic contingency.”
While it seems the Marine Corps has time before it makes a decision on how it can or will proceed, the Air Force is currently in the middle of choosing a future light attack platform.
The Air Force selected two aircraft — Textron Aviation AT-6 Wolverine and the Sierra Nevada/Embraer A-29 Super Tucano — to undergo more demonstration fly-offs, among other exercises, at Holloman Air Force Base, New Mexico. The demonstrations began May 7, 2018, and will run through July 2018, with the secretary herself expected to fly either or both aircraft at Holloman.The Senate Armed Services Committee, in its fiscal 2019 proposal, added $350 million to procure a future light attack aircraft.
The Defense Advanced Research Projects Agency (DARPA) wants the bomb you’ve been tinkering with at home. DARPA’s latest initiative is identifying emerging threats by mining everyday technologies. According to the agency’s press release, this effort, called Improv, “asks the innovation community to identify commercial products and processes that could yield unanticipated threats.” So DARPA wants that homemade bomb you’ve been building in your garage.
This means they want to see what you can make out of everyday household items so they can prepare a countermeasure. This kind of thinking is meant to tap into the natural resourcefulness and creativity of humans.
“DARPA’s mission is to create strategic surprise, and the agency primarily does so by pursuing radically innovative and even seemingly impossible technologies,” said program manager John Main, who will oversee the new effort. “Improv is being launched in recognition that strategic surprise can also come from more familiar technologies, adapted and applied in novel ways.”
The agency is looking to see how everyday household materials can be used to threaten U.S. national security. It may sound odd to think of American wreaking havoc with common materials, but it isn’t unheard of. In 1996, Timothy McVeigh purchased only enough ammonium nitrate to fertilize 4.25 acres of farmland at a rate of 160 pounds of nitrogen per acre, a formula commonly used to grow corn. This did not raise any eyebrows in Kansas. McVeigh later used the fertilizer to blow up Oklahoma City’s Alfred P. Murrah Federal Building, killing at least 168 people.
“U.S. national security was ensured in large part by a simple advantage: a near-monopoly on access to the most advanced technologies,” DARPA said in a press release. “Increasingly, off-the-shelf equipment… features highly sophisticated components, which resourceful adversaries can modify or combine to create novel and unanticipated security threats.”
To enter, interested parties must submit a plan for their prototype for the chance at a potential $40,000 in funding. Then, a smaller number of candidates will be chosen to build their device with $70,000 in potential funding. Finally, top candidates will enter the final phase, which includes a thorough analysis of the invention and a military demonstration.
The Department of Defense would like remind potential contributors that they should only build weapons within the bounds of their local, state, and federal laws.

The MARSOC (Marine Forces Special Operations Command) Communication Strategy and Operations office has confirmed that current MARSOC Commanding General, Major General Daniel Yoo, will be retiring and relinquishing his command and during a ceremony currently scheduled for June 26, 2020. MajGen Yoo assumed command of MARSOC, headquartered at Camp Lejeune, North Carolina, on August 10, 2018.
The Marine Corps Manpower & Reserve Affairs office confirmed with SOFREP that, at this time, incoming MARSOC commanding officer, Major General James Glynn, is scheduled to move in from his current post as Commanding General, Marine Corps Recruit Depot Parris Island and Eastern Recruiting Region. According to Glynn’s official bio, he “served at Headquarters Marine Corps (HQMC)—first as the Military Assistant to the Assistant Commandant of the Marine Corps and then as the Director of the Office of U.S. Marine Corps Communication. A native of Albany, New York, his service as a Marine began in 1989 after graduating from the U.S. Naval Academy with a Bachelor of Science Degree in Mechanical Engineering.”

Excluding any potential COVID-19-related delays or a last-minute change of plans by Headquarters Marine Corps, the timing of Yoo’s departure is in line with the historical two-year period that commanders spend in charge of the Marine Corps’ elite Special Operations component. However, in Yoo’s case the timing is leading many to question his public silence over supporting three of his own Marine Raiders whom he ordered to be sent to a general court martial for multiple charges related to the death of a defense contractor in Erbil, Kurdistan (Northern Iraq) on New Year’s Eve, 2018.
Video evidence would surface, confirming that the defense contractor (Rick Rodriguez) was highly intoxicated and clearly the aggressor in the situation and that Gunnery Sergeant Joshua Negron, Gunnery Sergeant Daniel Draher, and Chief Petty Officer Eric Gilmet did not use excessive force when defending themselves.

Yoo attended the funeral of Rick Rodriguez, but up to this point he has not once spoken a word of support for his men in spite of the fact that video proves they are innocent. Command silence on matters like this fuels speculation that the accused are guilty and mischaracterizes them of committing a drunken murder, yet Marine Corps and MARSOC leadership still choose to remain silent.
MajGen Glynn will soon be assuming the role of convening authority for the upcoming court-martial involving the MARSOC 3. As the new MARSOC Commanding General, Glynn will have the authority to review the MARSOC 3 case and determine whether to make changes to any aspect of it – including the ability to dismiss the charges. There is still time for him to take a fresh look at this case and do the right thing for his men. Marine Corps offices contacted by SOFREP have indicated that MajGen Glynn does not wish to provide comment at this time.
Nuclear blasts create fallout, which can harm you with large doses of radiation.
Cars offer little protection from fallout.
A surer way to survive in the aftermath of a nuclear explosion is to go indoors, stay put, and listen to the radio.
The first thing you’d see if a nuclear bomb exploded nearby is a flood of light so bright, you may think the sun blew up.
Wincing from temporary blindness, you’d scan the horizon and see an orange fireball. The gurgling flames would rise and darken into purple-hued column of black smoke, which would turn in on itself. As a toadstool-like mushroom took shape, the deafening shock front of the blast would rip through the area — and possibly knock you off your feet.
Congratulations! In this hypothetical scenario, you’ve just survived a nuclear blast with an energy output of about 10 kilotons (20 million pounds) of TNT. That’s roughly 66% of energy released by either atom bomb dropped on Japan in 1945.
No one could fault you for panicking after the sight and roarof a nuclear blast. But there is one thing you should never do, according to Brooke Buddemeier, a health physicist and radiation expert at Lawrence Livermore National Laboratory.
“Don’t get in your car,” he tells Business Insider — don’t try to drive, and don’t assume that the glass and metal of a vehicle can protect you.
Why vehicles and nuclear survival don’t mix
Avoiding driving after a nuclear blast is wise because streets would probably be full of erratic drivers, accidents, and debris. But Buddemeier says there’s another important reason to ditch the car: a fearsome after-effect of nuclear blasts called fallout.
Fallout is a complex mixture of fission products, or radioisotopes, that are created by splitting atoms. Many of the fission products decay rapidly and emit gamma radiation, an invisible yet highly energetic form of light. Exposure to too much of this radiation in a short time can damage the body’s cells and its ability to fix itself — a condition called acute radiation sickness.
“It also affects the immune system and the your ability to fight infections,” Buddemeier says.
Only very dense and thick materials, like many feet of dirt or inches of lead, can reliably stop the fallout.
“The fireball from a 10-kiloton explosion is so hot, it actually shoots up into the atmosphere at over 100 miles per hour,” Buddemeier says. “These fission products mix in with the dirt and debris that’s drawn up into the atmosphere from the fireball.”
Trapped in sand, dirt, cement, metal, and anything else in the immediate blast area, the gamma-shooting fission products can fly more than five miles into the air. The larger pieces drop back down, while lighter particles can be carried by the wind before raining over distant areas.
“Close in to the [blast] site, they may be a bit larger than golf-ball-size, but really what we’re talking about are things like salt- or sand-size particles,” Buddemeier says. “It’s the penetrating gamma radiation coming off of those particles that’s the hazard.”
Which brings us back to why a car is a terrible place to take shelter.
“Modern vehicles are made of glass and very light metals, and they offer almost no protection,” he says. “You’re just going to sit on a road some place [and be exposed].”
Buddemeier says he’s asked people what their knee-jerk response to a nuclear blast might be. It wasn’t comforting.
“There was actually a lot of folks who had this notion — and it may be a Hollywood notion — of ‘oh, jump in the car and try to skedaddle out of town if you see a mushroom cloud.'” he says.
However, fallout is carried by high-altitude winds that are “often booking along at 100 miles per hour,” he says, and “often not going in the same direction as the ground-level winds. So your ability to know where the fallout’s gonna go, and outrun it, are… Well, it’s very unlikely.”
What you should do instead of driving
Your best shot at survival after a nuclear disaster is to get into some sort of “robust structure” as quickly as possible and stay there, Buddemeier says. He’s a fan of the mantra “go in, stay in, tune in”.
“Get inside … and get to the center of that building. If you happen to have access to below-ground areas, getting below-ground is great,” he says. “Stay in: 12 to 24 hours.”
The reason to wait is that levels of gamma and other radiation fall off exponentially after a nuclear blast as “hot” radioisotopes decay into more stable atoms and pose less of a danger. This slowly shrinks the dangerous fallout zone — the area where high-altitude winds have dropped fission products. (Instead of staying put, however, a recent study also suggested that moving to a stronger shelter or basement may not be a bad idea if you first ducked into a flimsy one.)
“Try to use whatever communication tools you have,” he says. He added that a hand-cranked radio is a good object to keep at work and home, since emergency providers, in addition to broadcasting instructions, will be tracking the fallout cloud and trying to broadcast where any safe corridors for escape are located.
There is only one exception to the “no cars” rule, says Buddemeier: If you’re in a parking garage with your car, the concrete might act as a shield. In that case, you could stay there and listen to a radio inside your car.
If everyone followed these guidelines after nuclear blast, he says, hundreds of thousands of lives could be saved.
CLEVELAND, Ohio — The Republican National Convention started here Monday tapping into the ill-ease of the American public in the wake of terrorist attacks across the globe and domestic unrest. The theme for the first of four days was “Make America Safe Again,” a play on Donald Trump’s “Make America Great Again” tagline that he’s used from the beginning of his current run for president.
The prime time slate of speakers who took the stage at the Quicken Loans Arena started with Willie Robertson, one of the stars of the “Duck Dynasty” reality show, and television actor Scott Biao. They were followed by the first veteran in the lineup, former SEAL Marcus Luttrell, author of Lone Survivor.
Luttrell started his remarks by stating that he was born into a patriotic family that taught him “to die for any woman and to fight beside any man.” He said his father, who served in Vietnam, was “shamed out of his uniform” but instilled in his sons to “love this country and its people more than we loved ourselves.”
Luttrell was followed by Patricia Smith, the mother of Sean Smith, one of the four Americans killed during the attack on the consulate in Benghazi in 2012. “For all of this loss, for all of this grief, for all of the cynicism the tragedy in Benghazi has wrought upon America, I blame Hillary Clinton,” she said, which elicited a passionate response from the delegates on the convention floor, many of whom launched into a “lock her up” chant.
The topic of Clinton’s responsibility for the failure and tragedy of Benghazi continued with Mark Geist and John Teigen, two security contractors who fought off the attacks that night. The two men, who helped write 13 Hours, a book criticizing the State Department’s response to the attacks that was made into a Michael Bay movie last year, offered the crowd a lengthy, machismo-infused version of their experiences that night and left no doubt that they believe the lives of their comrades were lost because of the inaction of then-Sec. Clinton.
Arkansas Sen. Tom Cotton, a U.S. Army veteran who served in both Iraq and Afghanistan as a platoon leader with the 101st Airborne Division, jabbed at President Obama’s unwillingness to use the term “fundamentalist Islamic terrorist” when referring to ISIS and the associated network of lone wolves, saying that if Donald Trump was made commander-in-chief he would “call the enemy by its name.”
The energy in the building shifted into the next gear as former New York City mayor Rudy Giuliani took the stage and proclaimed that “the vast majority of Americans today do not feel safe. They fear for their children; they fear for themselves; they fear for our police officers who are being targeted, with a target on their back.”
Giuliani also hit Obama for his apparent reticence around labeling the terrorist threat in religious terms, saying, “Failing to identify them properly maligns all those good Muslims around the world who are being killed by them. They are killing more Muslims than anyone else.”
The lights faded to black as Giuliani left the stage, and the classic Queen hit “We are the Champions” boomed through the PA system. Donald Trump appeared as a backlit silhouette, and when the lights came back on he stepped to the podium and announced, “We are going to win so big,” and then introduced his wife Melania, who was the keynote speaker for the evening.
Mrs. Trump’s remarks, delivered with her heavy Eastern European accent, hit a number of general themes, including the fact that she was an immigrant who went through the naturalization process and became a citizen in 2006 and that her husband wasn’t one to give up on anything in life. (Media pundits were quick to point out that parts of her speech mirrored one given by First Lady Michelle Obama at the DNC in Denver in 2008, an accusation that Trump allies dismissed. “There’s no way that Melania Trump was plagiarizing Michelle Obama’s speech,” New Jersey Gov. and Trump proxy Chris Christie said.)
Donald Trump retook the stage at the end of his wife’s speech, and the two walked off to raucous applause from the delegates and other faithful in attendance. And, in what has to be viewed as a case of bad showmanship planning by either the RNC or the Trump team, retired Lt. Gen. Michael Flynn, former head of the Defense Intelligence Agency and a vocal critic of the Obama administration in spite of the fact that he’s a registered Democrat, walked to the podium to speak as a large majority of the audience streamed for the exits, assuming they’d seen the most important part of the program.
“The destructive pattern of putting the interests of other nations ahead of our own will end when Donald Trump is president,” Flynn said. “From this day forward, we must stand tougher and stronger together, with an unrelenting goal to not draw red lines and then retreat and to never be satisfied with reckless rhetoric from an Obama clone like Hillary Clinton.”
Flynn was followed Iowa Sen. Joni Ernst, another Army veteran, who told the dwindling crowd, “Our allies see us shrinking from our place as a leader in the world as we have failed time and again to address threats. They are looking for American leaders who are willing to stand up and say ‘enough is enough.'”
And by the time Texas Lt. Gov. Dan Patrick brought the first day’s proceedings to a close, Quicken Loans Arena was nearly empty.
American soldiers moving north during the liberation of the Philippines in 1944-1945 faced a real problem. Their men stranded on the islands at the outbreak of the war had been subjected to years of mistreatment, malnourishment, and disease. They needed to be liberated as soon as possible.
So the American forces wanted to rescue the prisoners as quickly as possible but couldn’t advance too quickly or the prisoners would be killed.
North of the advancing American soldiers was a camp near Cabanatuan, Philippines, where 512 American, Canadian, and British troops were held. Lt. Col. Henry Mucci, commander of the Sixth Ranger Battalion, moved with his Rangers and Alamo Scouts to work with Filipino guerillas to raid the camp and rescue the prisoners before the Japanese forces could repeat the Palawan Massacre.
The Americans slipped behind enemy lines on Jan. 28, 1945. The Alamo scouts split off and moved north of the camp to begin reconnaissance. Capt. Robert Prince, one of the Rangers, moved to a Filipino guerilla camp to meet Capt. Juan Pajota, a commander of local forces resisting the Japanese.

They devised a bold strategy where the 121 Rangers would assault the camp while the 275 guerillas would hold off a large Japanese force camped within earshot of the prison camp. They scheduled the attack for the evening of Jan. 29, only 24 hours after they had slipped behind enemy lines and begun reconnaissance.
Due to increased Japanese activity in the area, the assault was delayed another day. Late on Jan. 30, the Rangers and the guerillas began their assault.
The guerillas slipped up to blocking positions near the camp. Seventy-five of them set up a position to watch for forces that might come from nearby Cabanatuan while the other 200 others planted themselves firmly between the main Japanese encampment and the prison camp.
Meanwhile, the Rangers began a slow crawl across the open ground around the prison. To prevent them from being spotted, Pajota had suggested a plane fake distress near the camp.
A Navy P-61 flew over the camp and began shutting off and restarting one of his engines, causing it to backfire. Then, still simulating engine distress, he allowed the plane to lose altitude and dropped behind a nearby ridge. The Japanese focused on the plane while the attackers moved in.
The assault was scheduled for 7:30, but the main force of Rangers were surprised when the attack didn’t begin. The Rangers of Fox Company were ten minutes late in reaching their position.
At 7:40, the attack began. Fox company assaulted the camp from the rear while the main force, Charlie Company, slipped up to the front. Bazooka teams quickly eliminated enemy machine gun nests. One platoon of Charlie company began searching out guards and killing them while the other immediately began evacuating prisoners.
Within five minutes, Pajota and his guerillas began taking fire from suicidal Japanese forces. But they held the Japanese back, allowing the evacuation to continue.
Soon after 8 p.m., Prince searched through all the buildings to ensure all the prisoners had made it out. He then fired a flare to signal the all clear at 8:15, barely 35 minutes after the assault began. The prisoners and the Rangers began moving along their escape route to American lines. The scouts and the guerillas stayed behind to block Japanese forces.
