The iconic U-2 spy plane debuted in 1955, and it’s still deployable thanks to a meticulous inspection called the Programmed Depot Maintenance every 4,700 flight hours.
This incredibly complex process requires technicians to disassemble and strip the paint off the entire plane to analyze every part and make repairs. Over 1,800 individual parts are removed and revised and 40,000 rivets inspected. After completion, the aircraft is reassembled and repainted before returning to the flight line.
For a plane that’s flown over the Soviet Union, Cuba, Korea and other places around the world since its secret introduction to the inventory, it has proven its worth. The Air Force keeps 33 of them on standby and plans to keep it flying until at least 2019.
This time lapse video from Sploid shows the entire process in under two minutes:
Vigilance Elite just released footage from a training session with Reeves for John Wick: Chapter 3 – Parabellum, and you can see that he’s training like an operator, not just an actor. In the video below, trainer and former Navy SEAL Shawn Ryan walks Reeves through room clearing with a rifle — in particular, negotiating the “fatal funnel.”
This kind of dedicated training is just one reason why Reeves is highly respected and his films are so fun. Check out the video for a bit of Reeves-worship…but stay for the refresher in case you ever get into a sh*t sandwich.
Keanu Reeves Tactical Training for John Wick 3 with Vigilance Elite .MP4
“My character’s always in shit sandwiches,” jokes Reeves.
Reeves maintains a professional, respectful demeanor throughout the process, which is exactly the kind of attitude that bridges the divide between military and civilian audiences. Reeves is believable as an assassin because he puts in the work to understand weapons and tactics; military audiences can spot a phony a mile away and it ruins the cinematic experience.
Believe it or not, the United States Navy has a very fast testbed vessel — one that not only looks futuristic, but is also being used to test all sorts of futuristic technology. That vessel is known as the Stiletto, and while it looks like something out of science fiction, it’s actually 13 years old.

When you look at the Stiletto, your first impression, based on its shape, is that it’s some sort of stealthy vessel. That’s a common misconception. During a tour at the Navy League’s SeaAirSpace 2018 expo in National Harbor, Maryland, members of the Stiletto program explained that the ship’s radar cross section is about what you’d expect for a ship of its size.
The Stiletto’s hull is made from carbon-fiber composites.
The ship looks as it does because it has a carbon-fiber hull. The material is incredibly light — I had the opportunity to handle a roughly softball-sized chunk of the material and can tell you first-hand. While the exterior is durable (the ship has handled seas rough enough to make lab-acclimated scientists queasy), it’s also vulnerable to being punctured.
SEALs prepare to enter the Stiletto. The vessel is small, but can accommodate the SEALs’ vessel inside.

According to an official handout, the Stiletto has a top speed of 47 knots. However, during builders’ trials, the crew reported hitting a speed of 54 knots. Normally, the ship cruises along at a comfortable 30 knots and can go 750 nautical miles on one tank of fuel.
In addition to being able to carry a RHIB, the Stiletto can also launch drones.

But the Stiletto also has ample space – it easily accommodated a rigid-hull inflatable boat that was over 30 feet in length, and there was still plenty of space left over for other gear. The crew explained that adding new systems to the adaptable ship takes a few hours or a day at most.
The wide array of sensors on the Stiletto show how easy it is to add something new to try out.
One thing that was skimpy on the Stiletto, however, was the galley, which consisted of a microwave oven and stack of paper plates. The ship of the future, it seems, didn’t quite have everything.
The Navy is now integrating and preparing weapons systems for its advanced Ford aircraft carrier during a now-underway 12-month period called Post-Shakedown Availability (PSA) — one of several key final steps designed to prepare the ship for ocean warfare when the ship deploys in 2022.
While the Ford’s electromagnetic catapult, larger deck space and nuclear power technology are heavily emphasized in public discussion of the ship’s newer technologies, layered ship defenses, are commanding commensurate developmental attention – given the global threat environment.
This includes efforts to build in the latest interceptor missiles and close-range guns, such as the Evolved Sea Sparrow Block 2 (ESSM) and the Phalanx Close-In Weapons System (CIWS).
Therefore, alongside the more emphasized items for the PSA, such as the advanced weapons elevator and advanced arresting gear upgrades, preparing ship defenses for deployment will also function as an indispensable element of the Navy’s strategy for the Ford-class.

“The scheduled 12-month PSA/SRA will install remaining combat systems, complete deferred work and correct remaining discrepancies identified during sea trials and shakedown,” William Couch, Naval Sea Systems Command spokesman told Warrior Maven.
The PSA is intended to build upon lessons learned and adjustments emerging from previous testing.
The ship’s crew has been “conducting post-delivery testing and trial operations that identify construction and design issues. They have been extremely effective in identifying any issues early, which helps us address them prior to returning to the fleet.” Rear Adm. Brian Antonio, program executive officer for aircraft carriers, said in a published Navy statement.
During testing and developmental phases immediately preceding the start of the PSA, the Ford successfully completed fixed-wing and rotary-wing aircraft integration and compatibility testing, air traffic control center certification and JP-5 fuel system certification, Couch added in the statement.
Demonstrating the ship’s defensive systems was also a vital element of these preparations for the PSA. While carriers often travel in Carrier Strike Groups, protected by cruisers and destroyers, the platforms are increasingly being viewed as ships in need of their own organic defensive weapons.
This is particularly true in light of the often discussed threats of Chinese DF-21D “carrier killer,” a long range anti-ship guided missile reported to reach ranges greater than 900 miles.
There is much discussion about how the USS Ford’s massively-increased onboard power technology, driven by four 26-megawatt generators, will potentially enable emerging weapons, such as defensive lasers and railguns.
In the near-term, however, the USS Ford will use the PSA to solidify integration of several upgraded ship defense weapons.
“Besides carrying over 75 warplanes, the USS Ford has some serious destructive capability. Engineers and designers included ESSM (Evolved Sea Sparrow Missile), RAM (Rolling Airframe Missile), and a Mk-15 Phalanx CIWS,” a report from Engineering.com writes.

Upgraded Evolved Sea Sparrow Missile
The USS Ford is expected to deploy with the Evolved Sea Sparrow Missile Block 2, or ESSM, a weapon designed to track and destroy incoming enemy supersonic missiles and anti-ship missiles, among other threats.
The ESSM Block 2 is engineered with what’s called an active guidance system, meaning the missile itself can achieve improved flight or guidance to its target by both receiving and actively sending electromagnetic signals, Navy and industry ESSM developers told Warrior Maven in previous interviews.
The current ESSM missiles use what’s called a semi-active guidance system, meaning the missile itself can receive electromagnetic signals bounced off the target by an illuminator; the ESSM Block 2’s “active” guidance includes illuminator technology built onto the missile itself such that it can both receive and send important electromagnetic signals, Navy and Raytheon officials explained.
A shipboard illuminator is an RF signal that bounces off a target. The antenna in the nose in the guidance section [of the missile] sees the reflected energy and then corrects to intercept that reflective energy, the Raytheon officials told Warrior.
The emerging missile has an “active” front end, meaning it can send an electromagnetic signal forward to track a maneuvering target, at times without needing a ship-based illuminator for guidance.
Also, the missile is able to intercept threats that are close to the surface by sea-skimming or diving in onto a target from a higher altitude, Navy officials explained.
The MK-15 Phalanx CIWS
Phalanx Close in Weapons System
The Phalanx Close in Weapons System, or CIWS, is an area weapon engineered to use a high rate of fire and ammunition to blanket a given area, destroying or knocking enemy fire out of the sky before it can reach a ship. The Phalanx CIWS, which can fire up to 4,500 rounds per minute, has been protecting ship platforms for decades.
CWIS fires a 20 mm Vulcan cannon mounted on a swiveling base. An essay in Naval Forces magazine called “CIWS – the Last Ditch Defense,” further specifics that the weapon fires “armor piercing tungsten penetrater rounds with discarding sabots.” CIWS fires a M61A1 Gatling gun out to ranges of 3 km.
Navy officials say the latest CIWS Block IB provides ships the additional capability for defense against asymmetric threats such as small, high speed, maneuvering surface craft, slow-flying fixed and rotary-winged aircraft, and unmanned aerial vehicles.
A CIWS overhaul in recent years has consisted of numerous upgrades to the weapon itself, converting the existing systems into what’s called the Phalanx 1B configuration. At the same time, the CIWS overhaul also includes the development and ongoing integration of a new, next-generation radar for the system called the CIWS Phalanx Block IB Baseline 2, Navy officials explained.
The Phalanx Block IB configuration incorporates a stabilized Forward-Looking Infra-Red sensor, an automatic acquisition video tracker, optimized gun barrels (OBG) and the Enhanced Lethality Cartridges (ELC),
The FLIR also improves performance against anti-ship cruise missiles by providing more accurate angle tracking information to the fire control computer.
The OGB/ELC combine to provide tighter dispersion and increased first hit range, a Navy official added. The Phalanx 1B fires Mk 244 ammunition, using the Enhanced Lethality Cartridge specifically designed to penetrate anti-ship cruise missiles.
The Mk 244 ammunition is engineered with a 48 percent heavier tungsten penetrator and an aluminum nose piece, according to information from General Dynamics Ordnance and Tactical Systems.
The Phalanx Block IB Baseline 2 radar upgrade is a new digital radar that provides improved detection performance, increased reliability and reduction in sailor man-hours for system maintenance, developers said.
The Baseline 2 upgrade mitigates obsolete components inherent in the existing analog radar by introducing COTS-based (commercial off-the-shelf) signal processing coupled with a new signal source and mixer.
CIWS uses “Ku-band radar featuring closed-loop spotting technology capable of autonomously performing its own search, detect, evaluation, track, engage and kill assessment functions,” the Naval Forces essay writes.
The Baseline 2 radar also provides the Phalanx CIWS with “surface mode,” meaning it adds the ability to track, detect and then destroy threats closer to the surface of the water compared with previous models of the weapon, developers explained.

Russian diplomats delivered a message for those who want to ban killer robots: Russia will build them no matter what. That is the sum total of what happened during a week of discussion on the issue of weapons and vehicles operated by artificial intelligence in Geneva.
“According to the Russian Federation, the lack of working samples of such weapons systems remains the main problem in the discussion on LAWS,” the statement said. “Certainly, there are precedents of reaching international agreements that establish a preventive ban on prospective types of weapons. However, this can hardly be considered as an argument for taking preventive prohibitive or restrictive measures against LAWS being a by far more complex and wide class of weapons of which the current understanding of humankind is rather approximate.”
The Russians also claimed that there was a risk of harming civilian artificial intelligence capabilities, saying, “It is hardly acceptable for the work on LAWS to restrict the freedom to enjoy the benefits of autonomous technologies being the future of humankind.”
The Russian hard line comes as questions percolate about Russian compliance with other arms control treaties. Russia has already been accused of violating the 1987 Intermediate Nuclear Forces Treaty, prompting the United States to begin development of a new ground-launched cruise missile. A report from RealClearDefense.com noted that Russia’s force of Tu-22M3 Backfire bombers may have been modified in a manner that fits the definition of strategic bombers under the New START Treaty.
In the past, some arms control treaties have not prevented bad guys from using banned weapons. The Chemical Weapons Convention did not prevent the Islamic State of Iraq and Syria from using mustard agent against American troops in 2016.
How does a runner on second know when he should steal third? Does a batter automatically know when to bunt? When does a quarterback call an audible – and how can he communicate that play without the other team knowing just what he saw in their defense? Hand signals and codes are simple ciphers designed to communicate a simple message. It’s no different from what intelligence agents have been doing since days of Julius Caesar.
Sports teams have been using encrypted signals since before World War I. Most famously, the 1951 Giants put a man with a telescope in center field to read the opposing teams calls and signals. The Giants overcame an almost 14-game deficit that year to force a playoff with the Brooklyn Dodgers. From the Giants’ center field manager’s office, coach Herman Franks relayed the opposite teams’ signs to the bullpen using an electric buzzer system. The catcher’s call would then be relayed to the batter.
The scheme was simple intelligence tradecraft.
“These are simple messages being sent,” says Dr. Vince Houghton, the curator and historian of the International Spy Museum in Washington, D.C. “They take a basic step of encryption, the way an army encrypts tactical plans to attack or defend. You can let the enemy know what you’re going to do next, so you can’t send these messages in the clear.”
The reason the ’51 Giants encrypted their signals was the same reason they climbed back into the playoffs: unencrypted messages were easy to intercept, which made it so their hitters knew what the pitcher would do, giving them a huge advantage.
The relationship between sports cryptography and the military can go the other way, too. In Vietnam, Lt. Col. Iceal Hambleton was shot down in an EB-66 near the North-South Vietnam Demilitarized Zone. This was literally the worst situation for military intelligence. Hambleton not only had the intelligence vital to the Vietnam War, but the U.S. military’s entire Cold War-World War III contingency plans. If he was captured by the North Vietnamese, they would be able to give the Soviets the entire Strategic Air Command war plans.
Hambleton survived and the NVA knew exactly how valuable he was. While looking for extraction, he had to evade the NVA patrols looking for him while making his way to the rescue area. The problem was he had to be told how to get there over the radio – and an unencrypted radio was all he had.
Knowing Hambleton was crazy about golf – perhaps the best in the U.S. Air Force – the military fed him the info he needed to move using a simple substitution cypher. It took Hambleton a half-hour to figure out what they were doing.
“Instead of telling him to move south 100 meters, they would tell him to walk the first hole on Pebble Beach,” says Dr. Houghton. “He was tracked by using descriptions of golf course holes he knew well.”
Other codes included playing 18 holes, starting on No. 1 at Tucson National.
“They were giving me distance and direction,” Hambleton later explained. “No. 1 at Tucson National is 408 yards running southeast. They wanted me to move southeast 400 yards. The ‘course’ would lead me to water.”
Unlike using a radio, sports code has to be done in plain sight — that’s where the hand signals come in to play.

While working on a completely different project I discovered something curious on Amazon. That product was moldable thermoplastic pellets.
Shaped in balls like smaller-than-usual airsoft pellets, moldable thermoplastic melts at just 140F, can be formed like clay, and then increases in hardness as it approaches room temperature.
There are seemingly endless uses for this product, but I had a pet one in mind for the test: a US Optics turret tool.
With most scopes (several of them being US Optics) a simple hex wrench can be used to float turrets back to zero after obtaining a physical zero.
But no, not the case with the USO BT-10.
While official instructions say to press down with your palm on the top and rotate, the reality meant several friends and I tried in vain to accomplish this for about an hour.
And once you get it, it has to be pushed back in the same way.
Either way you cut it, it sucked on both ends.
So, a US Optics BT-10 tool it would be.
Firstly, you heat up some water at a medium temperature. Then drop some thermoplastic in place. Once it’s clear, then it’s pliable.
Then all you have to do is mold it around an object. I have found that it does not stick to treated metal but may to plastics (so use a release agent like PAM). As it comes to temperature, it becomes opaque again.
[Note that I did attempt to add texture which is why it looks so rough]
Does it work?
The extra area and easier grip makes floating turrets a HELLUVA lot easier with this scope.
The best part is, if you muck it up it can be re-melted and reused.

Everyone knows that when Navy SEALs arrive at their target, they can do some serious ass-kicking. But how they get to the point of attack is changing – and becoming more high-tech.
According to a report from TheDrive.com, the Combatant Craft Assault has been stealthily prowling the battlefield, giving SEALs new capabilities to insert into hostile territory and then make a clean getaway.
The CCAs reportedly took part in Eager Lion, a joint exercise in Jordan, and also got a moment in the spotlight when Army Gen. Joseph Votel, the commander of United States Central Command took a training ride in one.
According to AmericanSpecialOperations.com, the CCA is 41 feet long, and is capable of carrying M240 medium machine guns, M2 heavy machine guns, and Mk-19 automatic grenade launchers. The boat is also capable of being air-dropped by a C-17A Globemaster, making it a highly flexible asset.
These boats can operate from the well decks of Navy amphibious ships or afloat staging bases like USS Ponce (AFSB(I) 15) and USNS Lewis B. Puller (T-ESB 3), which departed this past June for a deployment to the Persian Gulf region.
The craft reached full operational capability this year. While initially built by United States Marine, Inc., Lockheed Martin is now handling maintenance of these boats, which are manned by Special Warfare Combatant Craft Crewmen. Two other stealthy special-ops boats, the Combatant Craft Medium and the Combatant Craft Heavy, are reportedly in various stages of development and/or deployment to the fleet.
There used to be a rough ranking system for people who followed sub warfare. The best diesel submarines are the most quiet when they aren’t running their diesel, followed by the best nuclear submarines, followed by crappy and older subs.
But over the past couple of decades, submarine technology has gotten so advanced that the engine might not even be the limiting factor. Now, sub hunters look for a lot more than a bit of engine or pump noise under the water.

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

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

(Absinthologue, CC BY-SA 3.0)
Just beneath that group is nuclear submarines that generate electricity and then use an electric motor to drive the propeller or the pump jets (pump jets are preferred because they are less likely to create cavitation, more on that in the next paragraph). America’s newest submarines fit into this category. They have a small disadvantage against advanced AIP diesel-electric because the nuclear reactors must be continuously cooled using pumps which generate some noise.
Many of America’s subs were created before pump jets matured and have more traditional propellers. At the right depths and propeller speeds, propellers cause cavitation where the water boils in the low-pressure zone near the propeller despite the low temperatures. The telltale bubbles collapse almost immediately, letting good sonar operators follow the noise directly to the enemy sub.
Regardless of whether the sub is using pump jets or conventional propellers, it’s less stealthy when the reactors provide power directly to the propeller. U.S. subs are transitioning to only generating power and then using the electrical power to control the engines. China recently claimed to have developed the components necessary for the same upgrade.

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

(U.S. Navy Mass Communication Specialist 2nd Class Andrew Schneider)
Sub hunters need solid sonar systems and well-trained operators that can distinguish an enemy sub running quiet from the surrounding ocean noise, especially if the sub moves into a noisy patch of ocean like littoral or tidal areas, where the water rushing over rocks and coral hides the acoustic signatures of all but the noisiest submarines.
While all truly modern navies can do this, not all ships are capable of hunting even older submarines, so older models still give an asymmetric advantage to a nation. But for modern navies like the U.S. and China, the competing sailors have to use every trick in their toolbox to retain an edge.
This is a relatively new development since Chinese subs were known as being laughably loud to U.S. forces just a few years ago. While it’s unclear in the unclassified world just how much China has closed the gap, they’ve made claims that they’re actually slightly ahead of the U.S. This seems unlikely, but China has shown off advanced technologies, like pump jets, that could put its tech within striking distance of the U.S.’
And its subs have twice threatened U.S. carriers, once surfacing well within torpedo range and once shadowing a U.S. carrier near Japan. The U.S. Navy might have spotted the subs and decided to not risk starting a war by engaging it, but it’s also possible that the Chinese subs actually got the jump on them.
Meanwhile, the U.S. has completed its own submarine surprise against China. In 2010, the U.S. surfaced three submarines simultaneously, one each near South Korea, The Philippines, and Diego Garcia, all within range of Chinese forces or the Chinese mainland. Between the three boats, they could carry 462 Tomahawk Land Attack Missiles.
So, it seems that in submarine warfare, the advantage still lies with the subs. But modern submariners are still counting on every advantage that their training, scientists, and engineers can give them, because in a small metal tube hundreds of feet underwater is a horrible time to find out you’re not as stealthy as you’d hoped.
How does a massively successful director like Zack Snyder follow up box-office smahes (and future box-office smashes) like 300, Man of Steel, Batman v Superman, and Justice League? If you answered a film retelling the magnificent rise of the first president of the United States in the style of 300, you guessed correctly. Speaking with Bloomberg Business, Snyder explains that George Washington is next on the docket.
He has a picture in his office of the Revolutionary War hero crossing the icy Delaware on his way to decimate the British in the Battle of Trenton. “We were talking about it,” Snyder says. “The first thing we asked was, well, how are we going to make it look? I pointed at this painting. It looks like 300. It’s not that hard.”
He isn’t wrong, but we’re guessing it will look something like a mix between the iconic painting and the epic illustration above.
US Night Vision is one of the largest distributors of night vision optics and accessories in the world. As such, they have a couple new products of interest that made their way to SHOT Show 2019.
The Harris F5032 Lightweight Night Vision Binocular has actually been around for a couple of years, but for whatever reason, Harris chose not to push it on the market and kept it on the back burner. This competitor to the L3 PVS1531 features white phosphor tubes and a unique close-focus technology that allows users to perform intricate tasks under night vision.
F5032 Lightweight Night Vision Binocular.
As many a user of helmet-mounted night vision has experienced, most NVGs will blackout when the user tilts their head to look upward. The F5032 has an intuitive vertical viewing capability that recognizes when the optics are in use and prevents the automatic tilt shutoff from activating, so that the goggles only shutoff when placed in the stowed position. This is sure to be a huge selling point for those who spend time working under aircraft or ascending vertical structures.
A view through the white phosphor F5032.
The F5032 has an integrated LED IR illuminator to reduce the need for external IR illumination devices. The image intensifier tubes are serviceable at the unit level, making it easier for them to be repaired without the extended downtime that comes from shipping them back to the company. The F5032 uses a standard dovetail mounting bracket for compatibility with the Wilcox NVG mount.
Also new from US Night Vision is the BCO LPMR-MK2 Low Profile Mission Recorder. This minimalistic recording device attaches to the eyepiece of the ocular lens of your night vision optic (optic specific) to record whatever you are viewing. The unit supports up to 128gb Micro SD for nine hours of record time with minute by minute seamless High Definition 1920×1080 30fps recording.
BCO LPMR-MK2 Low Profile Mission Recorder attached to a PVS14.
The LPMR-MK2 has an integrated microphone to capture audio and is externally powered via USB to accommodate a wide variety of battery sources. To make operation simple, the LPMR automatically begins recording when powered on, so there are no external buttons to fool with, and the operator doesn’t have to wonder if what if what they are seeing is actually being captured or not.
The unit weighs less than 1.5oz, so the added weight to night vision optics is minimal. The upfront placement of the device also reduces the amount of leverage placed on the helmet, so the user doesn’t have extra forward weight pulling down on their helmet. This recorder is sure to be a hit with military and law enforcement who have a need to record low-light training or real-world operations for after-action evaluation or courtroom purposes.
More information on these and other new products from US Night Vision can be found here.

In the opening hours of the next Korean War, the North could kill upwards of 250,000 people using just conventional artillery, to say nothing of nuclear weapons or ballistic missiles, a January 2019 Rand Corporation report found. Those numbers are just from the South Korean capital alone.
And there is little the United States could do about it.
The North’s big gun is essentially a self-propelled coastal defense gun, the Koksan 170 mm, mounted on a tank and firing rocket-propelled shells up to 40 miles in any direction. Since the crews work outside of the weapon and North Korea’s air force could do little to protect them, the North had to devise a means of reloading the guns after firing, when they’re exposed and vulnerable.
An aging Koksan 170mm artillery piece.
Some 10 million people live within firing range of the Korean demilitarized zone, living and working every day with hundreds of guns pointed at their heads. This includes the population of Seoul as well as the tens of thousands of U.S. and South Korean military personnel stationed on the peninsula. Most of them live within the 25-mile range of Communist artillery pointed at the South, but North Korea has some pieces that can fire as far as 125 miles, affecting a further 22 million people. It’s not a good situation for defending South Korea or protecting our forces.
“Conservative predictions of a likely attack scenario anticipate an initial artillery barrage focused on military targets, which would result in significant casualties,” said U.S. Army Gen. Vincent Brooks, head of U.S. Forces Korea. “A larger attack targeting civilians would yield several thousand casualties with the potential to affect millions… within the first 24 hours.”
North Korea has thousands of artillery pieces that could fire tens of thousands of rounds during a 10-minute barrage. The big Koksan 170 carries 12 rounds of its own before it has to go re-arm itself. Since any ammunition depots would be as vulnerable to enemy aircraft as the artillery themselves, North Korea has constructed thousands of reinforced underground bunkers near the DMZ to hold ammo and house the guns.
As a result, in an opening salvo, North Korean artillery are likely to use what military planners call a “shoot n’ scoot” tactic. The guns will come out of the bunkers to fire off their rounds and then go right back into hiding to reload and prepare for another volley in rapid succession. This will make it difficult for allied airpower to track and kill the weapons.
The best scenario for Seoul is that the Koksan 170 requires a specialized round to hit Seoul, one the North may have in limited quantities. Even if they do fire at a high rate, it’s likely the barrels of the weapons will heat up to a degree that the ideal rate of fire U.S. military planners plan against won’t be the actual rate used in combat. Another potential advantage for the UN forces is the area covered by the guns. If North Korea wants to destroy Seoul in the first few minutes of a war, all of its weapons would need to be trained on Seoul, work perfectly, and have the maximum rate of fire for a skilled crew – while UN planes and artillery are shooting back.
