Military doctrine identifies five domains of warfare — land, sea, air, space, and information. While borders and barriers define the four natural domains, the fifth dimension, with the advancements of artificial intelligence, is rapidly expanding with the potential to destabilize free and open international order.
Nations like China and Russia are making significant investments in AI for military purposes, potentially threatening world norms and human rights.
This year the Defense Department, in support of the National Defense Strategy, launched its Artificial Intelligence Strategy in concert with the White House executive order creating the American Artificial Intelligence Strategy.
The DoD AI strategy states the U.S., together with its allies and partners, must adopt AI to maintain its strategic position, prevail on future battlefields and safeguard order.
“The (executive order) is paramount for our country to remain a leader in AI, and it will not only increase the prosperity of our nation but also enhance our national security,” said Dana Deasy, DoD chief information officer.
Deasy also launched the Joint Artificial Intelligence Center in February 2019 to transform the DoD by accelerating the delivery and adoption of AI to achieve mission impact at scale. The goal is to use AI to solve large and complex problem sets that span multiple services; then, ensure the services and components have real-time access to ever-improving libraries of data sets and tools.
Col. Jason M. Brown is the Air Force Lead at the Joint Artificial Intelligence Center believes developing robust artificial intelligence capability is necessary to stay inside a potential adversaries decision making loop.
“The United States needs to drive the development of AI otherwise our adversaries will and we can’t rely that certain adversaries or rivals out there won’t develop AI that meets our standards when it comes to ethics, safety and surety,” said Col. Jason M. Brown, the Air Force lead for the JAIC.
For the DoD that also means working hand in hand with partners and industry leaders in technology and innovation to get smarter, faster.
At the 2019 Air Warfare Symposium, Mark Cuban, renowned entrepreneur and investor, spoke about the world industry competition in AI.
“It’s scary,” Cuban said. “AI is not just important — it’s everything. That’s how the battles (of the future) will be fought.”
Cuban explained China has a huge advantage because they are doing things the U.S. won’t and they have made AI a national focus over the last couple of years.
Vice Chief of Staff of the Air Force, Gen. Stephen Wilson discusses the need for developing artificial intelligence capabilities with Mark Cuban at the Air Force Association Air Warfare Symposium in Orlando. Fla. in Feb. 2019.

“In order to do AI it’s not just about capturing data, which is important, it’s not about algorithms and research into AI; it’s how fast can you process,” Cuban said. “If there’s somebody that has a (fabrication facility) in China that’s building more advanced processors that’s just as important as keeping track of warheads.”
Brown believes AI deterrence will soon be on par with the mission of nuclear deterrence.
“If our adversaries see us moving at a speed and scale because it’s enabled by AI, that will clearly get their attention,” Brown said. “I’d much rather be in the driver seat as we develop these capabilities than to play catch up.”

The US Army is considering various systems to better shield tanks and armored vehicles from RPGs, antitank missiles, and other enemy fire.
But the latest version of the RPG, a staple in the arsenals of Russia and other forces, may already be a step ahead of the active-protection systems the US may soon adopt.
The Pentagon has purchased active-protection systems to test out on Abrams tanks and Bradley and Stryker armored vehicles, and may even mount them on lighter vehicles, like the successor to the Humvee, according to a report from Scout Warrior.
“The Army is looking at a range of domestically produced and allied international solutions from companies participating in the Army’s Modular Active Protection Systems (MAPS) program,” an Army official told Scout Warrior.
The Army intends to outfit Abrams tanks with the Israeli-made Trophy APS and Bradley vehicles with the Iron Fist system, which is also Israeli-made. It plans to put the US-made Iron Curtain system on Stryker vehicles. (The Army leased several of the Trophy systems last spring, working with the Marine Corps to test them.)
“The one that is farthest along in terms of installing it is … Trophy on Abrams,” Lt. Gen. John Murray, the Army’s deputy chief of staff, said in a statement. “We’re getting some pretty … good results. It adds to the protection level of the tank.”
The US’s look to APS comes as other countries adopt the technology.
Israeli’s Merkava comes standard with the Trophy, as does Russia’s new T-14 Armata. Both Israel’s and Russia’s tanks, as well as the UK’s Challenger 2, are considered by US officials to be close to or at parity with the US’s mainstay, the Abrams tank. (Though some officials don’t consider the Armata fielded.)
As militaries have adopted active-protection systems and other means to up-armor tanks, arms makers have looked for new antitank weaponry to counter them. Whenever US vehicles equipped with APS join similarly outfitted vehicles in the field, they will face a new challenge from an old foe, the RPG.
The most recent variant, the RPG-30, unveiled in 2008, has a 105 mm tandem high explosive antitank round, and features a second, smaller-caliber projectile meant to bait the active-protection systems that have become common on armored vehicles in recent years.
A tandem HEAT round carries two explosive charges. One neutralizes a vehicle’s reactive armor (which uses explosions to counter incoming projectiles), and the other is designed to penetrate the armor of the vehicle itself.
“The novelty of the Russian rocket launcher is that two rockets are fired at the target at the same time. One is a so-called ‘agent provocateur’ 42 mm in caliber, followed a bit later by a primary 105-mm tandem warhead rocket,” Vladimir Porkhachyov, the director general of arms manufacturer NPO Bazalt, told Russian state news agency Tass of the RPG-30 in September 2015.
The RPG-30 reportedly cleared testing and went into active service with the Russian military sometime between 2012 and 2013. At that point, according to a 2015 report by Russian state-owned outlet Sputnik, the Pentagon put it on its list of “asymmetrical threats to the US armed forces.”
The effectiveness of the RPG-30 against active-protection systems, and whether those systems need be upgraded to adapt to the RPG-30 and similar munitions, remains to be seen. But the RPG — though limited by the size of its warhead — has long been potent on the battlefield, even against modern tanks.
The previous model, the RPG-29, was introduced in 1991 and is still in service with the Russian armed forces. It fires a 105 mm tandem HEAT round and can also fire a thermobaric fuel-air round against bunkers and buildings.
Russian RPG-29s were used by Hezbollah in the mid-2000s, deployed against Israeli tanks and personnel during the 2006 Lebanon War.
According to a Haaretz reportfrom the time, Hezbollah antitank teams using RPG-29s managed on some occasions to get through the armor of Israel’s advanced Merkava tanks.
In other cases, Hezbollah fighters used the RPG-29 to fire on buildings containing Israeli troops, penetrating the walls.
“The majority of Israel Defense Forces ground troops casualties, both infantry and armored, were the result of special antitank units of Hezbollah,” which used other antitank missiles as well, according to the Haaretz report, published in the final days of the conflict and citing intelligence sources.
Those RPG-29s were reportedly supplied to Hezbollah by the Syrian military, which got them from Russia. Moscow disputed those origins, however, with some suggesting they were exported from former Communist bloc countries after the fall of the Soviet Union.
In August 2006, a RPG-29 was used successfully against a British Challenger 2 tank in southern Iraq.
During operations in Al Amarah, an RPG-29 rocket defeated the reactive armor installed on the Challenger, penetrating the driver’s cabin and blowing off half of one soldier’s foot and wounding several other troops.
UK military officials were accused of a cover-up in 2007, after it emerged that they hadn’t reported the August 2006 incident.
Two years later, during fighting in Baghdad’s Sadr City — a Shiite neighborhood in the Iraqi capital — a US M1 Abrams tank was damaged by an RPG-29. (The US has long avoided reactive armor systems but accepted them in recent years as a cheap, easy way to up-armor vulnerable parts of the Abrams, particularly against RPGs.)
During fighting in Iraq, RPG-29s penetrated the armor on the Abrams tanks twice and the Challenger once, according to The National Interest. Other Abrams tanks in Iraq were knocked out by antitank missiles, like the Russian-made AT-14 Kornet.
The threat goes beyond tanks. Seven of eight US Army helicopters shot down in Afghanistan between 2001 and 2009 were brought down by RPGs.
RPGs remain in service around the world, filling the arsenals of both state and non-state actors, according to the Small Arms Survey. The weapon and parts for it have popped in arms bazaars in Libya in recent years.
The RPG-7, the RPG-29’s predecessor, would be or would likely be used by forces in Eastern Europe, the Middle East and North Africa, sub-Saharan Africa, as well as Central, South, and East Asia.
Regular and irregular forces in Latin America also have RPGs, and the weapons have made their way into the hands of criminal groups in the region. The Jalisco New Generation cartel reportedly used one to down a Mexican military helicopter in early 2015.
Both vessels have roughly the same capabilities. They both provide area air-defense while also being able to attack surface ships and submarines.
The Ticonderoga-class cruiser’s main battery consists of two 61-cell Mk 41 vertical-launch systems. These can hold a wide variety of missiles, including the RIM-66 SM-2 Standard Missile, the RIM-174 SM-6 Extended Range Active Missile, the RIM-162 Evolved Sea Sparrow Missile, and the BGM-109 Tomahawk cruise missile. These cruisers also have two five-inch guns, two triple Mk 32 launchers for 12.75-inch torpedoes, two Mk141 quad launchers for the RGM-84 Harpoon, and two Mk 15 Phalanx Close-in Weapon Systems.
The Slava-class cruisers have 16 SS-N-12 “Sandbox” anti-ship missiles, 64 SA-N-6 “Grumble” surface-to-air missiles, two SA-N-4 “Gecko” launchers (each with 20 missiles), a twin 130mm gun, two quintuple 21-inch torpedo tube mounts, and six AK-630 30mm Gatling guns. This is a fearsome arsenl, but it leaves the Slava somewhat short on land-attack capability.
So, what happens when you pit these two powerhouses against each other? Of course, it depends in large part on who sees the other first. The Slava can operate one Ka-27 Helix helicopter compared to two Sikorsky MH-60R Seahawks on a Ticonderoga. This gives the Ticonderoga an edge, since the two Seahawks could, through triangulation of the Slava’s radar, give a good enough fix for the Ticonderoga to fire its Harpoons.
The key part of this hypothetical battle is the exchange of anti-ship missiles. The Slava has twice as many missiles as the Ticonderoga — each with a range of 344 miles — and a conventional warhead of roughly one ton that could tear a Ticonderoga apart, but these missiles fly at high altitude and, despite going more than twice the speed of sound, are easy pickings for the Aegis system onboard the Ticonderoga. Here, the Ticonderoga’s Harpoons may be more likely to get a hit or two in, despite the Slava’s missile armament. The SA-N-6 may have a long range, but the Harpoons come in at very low altitude. At least one or two Harpoons will likely hit the Slava. The Ticonderoga’s MH-60R Seahawks, if equipped with AGM-119 Penguin anti-ship missiles, could provide a second volley. At least one of the Penguins would likely hit as well.
After this exchange, the Slava will likely need to deal with fires, flooding, and disabled combat systems. From here, the Ticonderoga is left with two options: fire five-inch guns equipped with the Vulcano round or take the risk of closing to finish the job. Getting too close, however, would put the Ticonderoga within range of the Slava’s torpedo tubes, which could seriously damage — if not sink — the American cruiser.
So in a fight between a Russian missile cruiser and an American missile cruiser, who would win? At the end of the day, we’d put our money, as we always do, on the American Ticonderoga-class cruiser.
The Stinger missile is America’s premier short-range air defense weapon, featuring in-flight guidance and an almost 7-pound warhead that sends shrapnel ripping through planes, helicopters, and pretty much anything else flying low. It can even be shot against ground vehicles when necessary.
Recently, the missile’s manufacturer has created a new proximity fuse for the weapon — and it just passed qualification testing with flying colors.
U.S. Navy Mass Communication Specialist Seaman Aaron Kiser, assigned to the USS Bataan (LHD 5), practices target tracking with a Stinger missile training system aboard the Bataan, May 8, 2014.
(U.S. Marine Corps Sgt. Austin Hazard)
The Stinger is a hit-to-kill weapon, meaning it always tries to physically impact the enemy target before it goes off. That turns the skin of the targeted aircraft into shrapnel that rips through the rest of the aircraft, maximizing damage to engines, fuel tanks, and even the pilots. It usually ends up near the engine, since the weapon uses heat to track targets.
But making contact with the target isn’t always necessary, as the missile itself creates some shrapnel that will tear through the target’s skin. So, if it were to explode nearby its target, it’s still likely to damage or destroy the craft.
Now, the missile is being outfitted with a better proximity fuse that achieved a 100-percent hit rate during testing at Eglin Air Force Base, Florida.
That’s great news for Stinger missile shooters. The weapon can be carried by ground troops or mounted on ground vehicles or helicopters, but firing the weapon is risky, especially against ground-support jets or helicopters.
If the Stinger crew fires the weapon and misses, whether because of a malfunction, shooter error, or the target’s defenses, they’re potentially in for a world of hurt. That’s because it always takes time to fire a second missile, especially for ground troops firing the MANPADS, which is a tube with a single missile in it.
That means a very pissed off and scared pilot is going to turn around and follow the smoke plume back it its source, and the pilot is likely going to hit the missile source with everything they have available to drop and fire.

But with a proximity fuse, a missile that would otherwise be a near-miss will still go off, generating as much damage and shrapnel as it can. That means the helicopter that would be pivoting to attack is now suffering from damage. Hopefully, the damage is in the cockpit, control surfaces, or engine. A proximity detonation might even still be enough to destroy the target outright.
If not, then at least the crew on the ground has some breathing room as the air crew tries to get an idea of how damaged they are. This could be enough time for troops on the ground to get under cover or concealment or even to get off another shot.
This is especially useful against drones which typically don’t require as much damage to be completely destroyed. And, considering just how much more prevalent drones are becoming, that could be key for future air defenders trying to maintain an air defense umbrella as Chinese or Russian forces test their defenses. All four Department of Defense branches carry the missile in combat.

Currently, the weapon is most widely deployed in single-shot missile tubes and carried by air defense squads on the ground. There’s even an Army air defense battery that can jump these tubes into combat with other airborne troops. There’s also the Avenger system, a modified Humvee with eight missiles mounted on it.
“Measured by its major accident rate per 100,000 flight hours, which is the military standard, the Harrier is the most dangerous plane in the U.S. military,” said Los Angeles Times reporter Alan C. Miller in the video below. “Overall the Marines have lost more than one-third of the entire Harrier fleet to accidents.”
The first Harrier model, the AV-8A had a Class A mishap rate of 31.77 accidents per 100,000 flight hours. The Marines improved the rate to 11.44 per 100,000 hours with the introduction of the AV-8B in the mid-1980s, according to Miller.
By contrast, the Harrier has more than twice the accident rate of the F-16, more than three times the rate of the F/A-18, and about five times the rate of A-10.
Despite its astronomical accident rate, the fighter is beloved and remains in service more than 40 years since its introduction in 1971.
“One Marine general who flew the plane early on described it as an answer to a prayer,” Miller said.
The Corps’ need for an aircraft with a vertical landing and short takeoff capability can be traced to the 1942 Battle of Guadalcanal. The Marines lost over 1,000 men during that fight and felt abandoned by the Navy to fend for themselves.
“Since then, the precept that the Marines in the air should protect the Marines on the ground has been an essential part of the Corps’ ethos,” Miller said.
This History Channel video shows how the Harrier supports the Marine Corps’ mission to fight anywhere, anytime regardless of the risks:
The US military has long explored the idea of replacing its M-16 assault rifle with something newer and deadlier. From the 1990s onward, German arms giant, Heckler & Koch, was heavily involved in helping the US Army attempt to reach that objective, creating newfangled firearms that bear considerable resemblances to the guns you’d find in futuristic, sci-fi movies and TV shows.
The XM8 was one of these rifles developed by H&K in the early 2000s as one of a number of alternatives to the M-16 and its derivative M4 carbine. Born as a scaled-down replacement for another H&K prototype — the XM29 — the XM8 entered a limited production run in 2003, concluding just two years later.
Like the M-16 and M4 platforms, the XM8 also utilized the 5.56 x 45 mm NATO round. Built as a modular weapon and based on the G-36 rifle, then in use with the German military, soldiers could adapt their XM8s while in the field to serve in a variety of roles.
A barrel swap and changing the stock could quickly take the XM8 from its carbine variant to a smaller personal defense weapon, similar in size to an MP5 submachine gun. An XM320 (now the M320, the Army’s standard-issue grenade launcher) could be mounted to the weapon with considerable ease for added firepower.
If a platoon out in the field needed a ranged weapon, the XM8 could be retooled accordingly by simply exchanging the barrel for a longer one, adding a more powerful scope, and a collapsible bipod. Should the situation and scenario call for something with more sustained rates of fire, the XM8 could even be turned into a light machine gun with a rate of fire between 600 to 750 rounds per minute.
To top it off, the XM8 wasn’t just light and extremely versatile, it was also cheaper to produce than the M4 carbine — the rifle it was designed to supplant. Proven to be fairly reliable during “dust tests,” even when compared against the M4, the XM8 was, on the surface, the ideal replacement rifle.
In fact, in the latter stages of the XM8 program, even the Marine Corps demonstrated an interest in testing and potentially buying the new rifle. Should the Department of Defense have picked it up, the gun would have been produced entirely in Georgia, in cooperation with other brand-name defense contractors.
In 2005, however, the program was shelved and quickly canceled. According to retired Army General Jack Keane, a huge proponent for replacing the M4, the XM8 program fell victim to the layers of bureaucracy that typically develop in military procurement schemes. Outside of the bureaucratic issues plaguing the new rifle, there were also technical shortcomings H&K addressed very poorly.
The weapon’s integral optical sight was partially electronic and, thus, required battery power. As it turns out, the original batteries for the weapon lost their charge too quickly and needed to be replaced. Unfortunately, the new batteries added weight to the rifle — the exact opposite of what the Army wanted.
Battery woes were the least of the Army’s concerns. Soldiers would have to worry about burning their fingers on the XM8’s handguards, which were very susceptible to overheating and even melting. The solution there was to also replace the handguard, adding even more weight. At the same time, unit production costs began to balloon as a result of the fixes created to refine the weapon.
While the US military was decidedly against the XM8, Heckler & Koch found a new customer overseas just two years after the XM8 program was canned. Though it didn’t meet the DoD’s standards for a new service rifle, the German arms manufacturer argued that it would still be an effective weapon with its kinks worked out.
As it turns out, the Malaysian Armed Forces were very interested in buying a small number of the futuristic rifles for their special operations units, namely Pasukan Khas Laut, their naval special warfare force, also known as PASKAL. By 2010, PASKAL troopers began using the XM8 to reduce reliance on their M4A1 SOPMOD carbines, alongside other H&K products like the HK416 and the G-36.
With the fear that hordes of Russian tanks would storm through the Fulda Gap at the start of World War III, the United States Army looked for an advanced helicopter.
The first attempt, the AH-56 Cheyenne, didn’t quite make it. According to GlobalSecurity.org, the Cheyenne was cancelled due to a combination of upgrades to the AH-1 Cobra, and “unresolved technical problems.”
The Army still wanted an advanced gunship. Enter the Apache, which beat out Bell’s AH-63.
The Apache was built to kill tanks and other vehicles. An Army fact sheet notes that this chopper is able to carry up to 16 AGM-114 Hellfire missiles, four 19-round pods for the 70mm Hydra rocket, or a combination of Hellfires and Hydras, the Apache can take out a lot of vehicles in one sortie.
That doesn’t include its 30mm M230 cannon with 1200 rounds of ammo. The latest Apaches are equipped with the Longbow millimeter-wave radar.
According to Victor Suvarov’s “Inside the Soviet Army,” a standard Soviet tank battalion had 31 tanks, so one Apache has enough Hellfires to take out over half a battalion. Even the most modern tanks, like the T-90, cannot withstand the Hellfire.
Then, keep this in mind: Apaches are not solo hunters. Like wolves, they hunt in packs. A typical attack helicopter company has eight Apaches.
So, what would happen to a typical Russian tank battalion, equipped with T-80 main battle tanks (with a three-man crew, and a 125mm main gun) if they were to cross into Poland, or even the Baltics?
Things get ugly for the Russian tankers.
That Russian tank battalion is tasked with supporting three motorized rifle battalions, in either BMP infantry fighting vehicles or BTR armored personnel carriers, or it is part of a tank regiment with two other tank battalions and a battalion of BMPs. In this case, let’s assume it is part of the motorized rifle regiment.
This regiment is slated to hit a battalion from a heavy brigade combat team, which has two companies of Abrams tanks, and two of Bradley Infantry Fighting Vehicles, plus a scout platoon of six Bradley Cavalry Fighting Vehicles.
A company of Apaches is sent to support the American battalion. Six, armed with eight Hellfires and 38 70mm Hydra rockets, are sent to deal with the three battalions of BMPs. The other two, each armed with 16 Hellfires, get to deal with the tank battalion.
According to Globalsecurity.org, the AN/APG-78 Longbow radars are capable of prioritizing targets. This allows the Apaches to unleash their Hellfires from near-maximum range.
The Hellfires have proven to be very accurate – Globalsecurity.org noted that at least 80% of as many as 4,000 Hellfires fired during Operation Desert Storm hit their targets.
Assuming 80% of the 32 Hellfires fired hit, that means 25 of the 31 T-80 main battle tanks in the tank battalion are now scrap metal.
Similar results from the 48 fired mean that what had been three battalions of 30 BMPs each are now down to two of 17 BMPs, and one of 18, a total of 52 BMPs and six T-80 tanks facing off against the American battalion.
That attack would not go well for Russia, to put it mildly.
The strike on Shayrat Air Base was intended to take out a number of targets, but one plane in particular was top of the list: The Su-22 Fitter.
According to Scramble.nl, two squadrons of this plane were based at the Shayrat air base that absorbed 59 T-LAMs. But why was this plane the primary target, as opposed to the squadron of MiG-23 Floggers? The answer is that the versions of the MiG-23 that were reportedly based there were primarily in the air-to-air role. The MiG-23MLD is known as the “Flogger K” by NATO. The two squadrons of Su-22 Fitters, though, specialized in the ground attack mission.
According to militaryfactory.com, the Su-22 is one of two export versions of the Su-17, which first entered service in 1969. Since then, it has received progressive improvements, and was widely exported to not only Warsaw Pact countries but to Soviet allies in the Middle East and to Peru. The Russians and French teamed up to modernize many of the Fitters still in service – and over 2,600 of these planes were built.
According to the Encyclopaedia of Modern Aircraft Armament, the Su-17/Su-20/Su-22 Fitter has eight hardpoints capable of carrying up to 11,000 pounds of munitions. It also has a pair of MR-30 30mm cannon. It is capable of a top speed of 624 knots, according to militaryfactory.com.
The Fitter has seen a fair bit of combat action, including during the Iran-Iraq War, the Yom Kippur War, Desert Storm, Afghanistan, and the Russian wars in Chechnya.
Recently, it saw action in the Libyan Civil War as well as the Syrian Civil War.
While it has performed well in ground-attack missions, it was famously misused by then-Libyan dictator Muammar Qaddafi to challenge U.S. Navy F-14 Tomcats over the Gulf of Sidra in 1981. Both Fitters were shot down after an ineffectual attack on the Tomcats.
During Desert Storm, the Iraqi Air Force lost two Su-22s, then two more during Operation Provide Comfort.
The Fitter did get one moment in the cinematic sun, though. In the Vin Diesel action movie “XXX,” two Czech air force Fitters made a cameo during the climactic sequence.
Sea bass is considered a culinary delicacy around the world. The Chilean sea bass, in fact, often turns up on five-star restaurant menus. But if you’ve been keeping up with the times, you know that there’s a new, American sea bass out in the ocean that has a very big bite. We’re talking something that can takes a chunk out of the metallic denizens of the ocean, both surface-dwelling warships and the subs that lurk beneath.
Okay, it’s not exactly a “sea bass,” but rather a “CBASS,” or Common Broadband Advanced Sonar System, and it’s a huge upgrade to the MK 48 Mod 7 torpedo currently in service.
You may be wondering why the United States Navy is looking to improve on the MK 48 — especially since a U.S. sub hasn’t fired a torpedo in anger since World War II.

The fact is that technology doesn’t stand still, and the Navy learned the hard way during World War II that reliable torpedoes are essential. Learning from history is why the US is constantly pushing to improve its torpedoes. And it’s a good thing, too, because Russia and China have been pushing to upgrade their naval forces in recent years.
According to Lockheed, the newest Mod 7 will include a suite of new, wide-band sonar systems, advanced signal processing, and enhanced guidance systems. All of this is attached to a 650-pound, high-explosive warhead atop a 3,500-pound torpedo.
43 years after this test shot, the MK 48 Mod 7 CBASS ensures that the United States Navy’s subs can still kill anything afloat — or under the surface.
(U.S. Navy photo)
Official handouts credit the MK 48 with a top speed in excess of 28 knots, a maximum range of over five nautical miles, and an operating depth of at least 1,200 feet. However, the real specs are probably much better in terms of performance. Unofficial figures show the torpedo actually has a top speed of 55 knots and a maximum range of 35,000 yards (almost 20 miles).
The United States Navy and the Royal Australian Navy have teamed up to produce this very deadly “fish.” In this case, the CBASS is the predator.
If you’ve been on the internet, you probably at some point have seen pitches for retirement in Latin America. Believe it or not, those advertisements probably would have been just as applicable to many classic war planes in addition to people.

In some ways, it shouldn’t be a surprise. But why did Latin America become a way for some classic planes to avoid the scrapyard or become a target drone?

Well, drug cartel violence aside, there isn’t a lot of risk for a major conflict in Latin America. The last major war involving a Latin American country was the Falklands War in 1982. Before that, there was the Soccer War. The drug cartels and guerrilla movements haven’t been able to get their own air forces.

In short, most of those countries have no need for the latest and greatest fighters, which are not only expensive to buy but also expensive to operate. Here’s the sad truth about those countries: Their economic situation doesn’t exactly allow for them to really buy the latest planes. Older, simpler classics have been the way to go, until they get replaced by other classics.

Today, Latin America is a place where the A-37 Dragonfly, best known for its service in Vietnam, is still going strong. Other classics, like the F-5 Tiger, are also sticking around in small numbers. In short, these planes will protect Central and South America for a long time — even after their glory days.
The F-35 Lightning, the ultimate result of the Joint Strike Fighter program, is entering service with the Marines and Air Force. Its prototype, the X-35, won the competition in 2001, but it wasn’t the only serious contender. In fact, we were close to going in a very different direction. Boeing had its own entry into the JSF competition, the X-32, which would have been the F-32 had it won.
While the F-35 looks like a single-engine version of the F-22, the X-32 bore a resemblance to the A-7 Corsair, which is affectionately known as the SLUF, or “short little ugly f*cker.” Like the X-35, Boeing’s offering was to be cheaper than the F-22 Raptor and was intended to replace the F-16 Fighting Falcon, F/A-18 Hornet, A-10 Thunderbolt, and AV-8B Harrier.

The X-32 and X-35 were selected to take part in a fly-off in 1996, beating out designs from Northrop Grumman and McDonnell Douglas.
The X-32 was based on reliable technology. To achieve Vertical/Short Take-Off and Landing capability, it used a thrust-vectoring system similar to that used by the AV-8B Harrier. It had a top speed of 1,243 miles per hour and a maximum unrefueled range of 979 miles. It packed a M61 20mm gun (again, proven technology) and was capable of carrying as many as six AIM-120 Advanced Medium-Range Air-to-Air Missiles or up to 15,000 pounds of bombs.
The X-32’s big chin inlet, which gave it the appearance of a futuristic A-7, netted it the nickname “Monica.”
Lockheed’s X-35 used a separate lift-fan, much like the failed Yak-141 fighter. That gave it a performance edge over the X-32. As a result, “Monica” ended up losing out.
Both X-32 prototypes survived and have since been sent to museums.

The Civil War was one of the first industrialized wars, helping lead the world from battles conducted by marching men with muskets around each other on a large field to battles fought between small, quick-moving formations with repeating rifles, quick-firing guns, and higher-powered artillery. But not all of the weapon designs that debuted had a lasting effect on warfare.
And one of the designs that fell by the wayside was the quite weird “steam-powered cannon.”
As the world entered the late 1800s, breakthroughs in technology like steam engines and metallurgy allowed the world to make great industrial breakthroughs, and weapon designers hoped to harness those breakthroughs to make the U.S. military more powerful.
Historically, steam powered guns worked similarly to a conventional rifle, but instead of relying on gunpowder exploding to create high pressure and propel the bullet out of the barrel, they featured a chamber filled with water that would be heated into steam.
When water is heated into steam, it expands to 1,600 times its starting volume. So, it can give a bullet plenty of umph, but it takes a lot of time and heat to build up the pressure necessary to fire the weapon.
But Joslin and Dickinson were at the forefront of a new, steam-powered weapon design. Instead of using steam to build up pressure in the firing chamber, a steam engine would quickly rotate a mechanism and fire the round using centrifugal force.
Basically, this is a mechanized version of David and his sling to hit Goliath, but at 400 rounds per second.
The design showed promise, but the inventors had a falling out, so Dickinson created his own version and won funding for a prototype in 1860. By 1861, it was on display in Baltimore. History buffs will notice that the Civil War started in 1861, so this was an auspicious time to show off a new weapon design. Which, yes, could fire 400 balls per minute.
A steam engine powered a rotary wheel that flung ball ammunition in a closed circle before releasing it at high speeds from a barrel that could pivot within a large metal shield protecting the crew. The entire device was weighty, requiring a large boiler in addition to the barrel, rotary, and shield, and typically had to be moved with horses.
A member of the crew needed to keep feeding balls into the weapon as it tore through rounds. And it wasn’t horribly accurate, so they really needed to keep the balls going. While the weapon is sometimes described as a cannon, it fired .38-caliber rounds, larger than a 7.62mm round but still 24 percent smaller than a .50-cal.
But the worst shortcoming of the weapon was the actual speed of the rounds when they left the barrel. The centrifugal force couldn’t generate nearly the velocity that a chemically propelled or even steam-pressured round enjoyed. In fact, the Mythbusters built one and tested it, and they couldn’t get the rounds to pierce a pig at just a few feet.
Media coverage of the weapon at the time managed to muddle up some details, and the weapon became associated with Ross Winans, a states-right activist and steam expert in Maryland. The public became worried that this was a super weapon and Winans could deliver it to the Confederacy. The weapon even became known as the Winans Gun.
Baltimore police seized the weapon and then returned it to Dickinson who later tried to sell it to the Confederates. Union forces seized the weapon and it served during the war in a number of defensive positions at infrastructure in the North, but it never saw combat.
While it would be cool to say that the weapon went on to change warfare or inspire new weapons that were wildly successful, the truth is that the invention of the Gatling gun and then proper machine guns made the steam-powered Winans Gun unnecessary.
And while the Winans showed some promise during the Civil War, when its high rate of fire made it seem worth the effort to improve the weapon’s muzzle velocity, other weapon breakthroughs that were incompatible with the Winans relegated it to the dustbin.
The increased prevalence of rifled barrels didn’t work well with centrifugal weapons, and weapon cartridges allowed other weapons to catch up in rate of fire but didn’t benefit centrifugal weapons. And as it became clear that attacking forces needed to become more mobile, a massive weapon requiring a steam boiler was a clear loser.
Steam obviously still has a role in warfare, nearly all nuclear-powered weapons we’ve ever designed used steam to carry the power from the reactor. But steam projectiles have, sadly, disappeared, ruining our plans for the SteamPunk Revolution.
There’s a reason that the M2 .50-caliber machine gun design has endured since John Browning first created it 100 years ago, in 1918: The mechanical reliability of the weapon and ballistics of the round are still exactly what a soldier needs to kill large numbers of people and light vehicles quickly at long range.
Here’s how it works and how it affects a human body.

First, the M2 and its ammunition can be legally used to target enemy personnel, despite apersistent myth that states it can only be aimed at equipment. That said, it isn’t designed solely for anti-personnel use. An anti-personnel specific weapon usually has smaller rounds that are more likely to tumble when they strike human flesh.
Then, there’s the cavitation,which has two parts. The first cavity is the permanent one:the open space left from the laceration discussed above. But there’s a second, temporary cavity. As the round travels through the body, it’s crushing the flesh and pushing it out of the way very quickly. That flesh maintains its momentum for a fraction of a second, billowing out from the path of the bullet. The flesh can tear and cells can burst as the tissue erupts outward and then slams back.
In this GIF of ballistics gel taking a .50-cal. round, you can see all three effects. There’s the laceration and crushing immediately around the bullet, the huge cavity as the gel flies apart, and the shockwave from that expansion as it forces the gel to fly outwards before re-compressing. The cavitation and re-compression is so violent that you can see a small explosion in the first block from the compressing air.
Finally, there’s the shock wave. That temporary cavity discussed above? The flesh all around it is obviously compressed as the cavity expands, and that’s where the shock wave starts. The cavity pushes outward, compressing the flesh and the energy in the compressed flesh keeps traveling outward until it dissipates. This can also cause separations and tears. In extreme situations, it can even cause damage to nerve tissue, like the spinal cord and brain.
Typical rifle rounds generally aim to maximize the first two effects, laceration and crushing and cavitation. A relatively short, small round — 5.56mm or .223 caliber in the case of the M16 — travels very quickly to the target. When it hits, it quickly begins to yaw and then tumble, depositing all of its kinetic energy to create a large, temporary cavity. And the tumble of the round allows it to crush and cut a little more flesh than it would if flying straight.
But maximizing design for cavitation is maximizing for tumble, and that can make the round more susceptible to environmental effects in flight, making it less accurate at long range.

But Browning wanted the M2 to be accurate at long ranges, so he opted for a big, heavy round with a sharp tip. That’s great for flying long ranges and punching through the skin of a vehicle, but it can cause the bullet to punch right through human flesh without depositing much kinetic energy, meaning that it only damages the flesh directly in the path of the round.
But there’s a way to still get the round to cause lots of damage, even if it’s going to pass right through the enemy: maximizing its speed and size so that it still sends a lot of energy into the surrounding flesh, making a large cavity and creating a stunning shockwave. Basically, it doesn’t matter that the round only deposits a fraction of its energy if it has a ton of energy.
The M2 fires rounds at a lower muzzle velocity than the M16 and at similar speeds to the M4, but its round is much larger and heavier. The M33 ball ammo for the M2 weighs almost 46 grams, while the M16’s NATO standard 5.56mm round weighs less than 4 grams. That means, flying at the same speeds, the M2 .50-cal. has 11 times as much energy to impart.

It also maintains more speed during flight. So, when the M33 round from the M2 hits a target, it does usually pass through with plenty of its kinetic energy left with the exiting round. But it still cuts a massive path through its target, doing plenty of damage from the first effect. And it compresses plenty of flesh around it as it forces its way through the target, creating a large permanent cavity and a still-impressive, temporary cavity.
But it really shines when it comes to shock wave damage. The M33 and other .50-cal. rounds have so much energy that even depositing a small fraction of it into the surrounding tissues can cause it to greatly compress and then expand. With a large round traveling at such high speeds, the shock wave can become large enough to cause neurological damage.

(U.S. Army National Guard Spc. Andrew Valenza)
Yeah, the target’s flesh deforms so quickly that the energy can compress nerves or displace them, shredding the connections between them and potentially causing a concussion.
And all of that is without the round hitting a bone, which instantly makes the whole problem much worse for the target. All rounds impart some of their energy to a bone if they strike it, but with smaller rounds, there’s not all that much energy. With a .50-cal, it can make the bone explode into multiple shards that are all flying with the speed of a low-velocity bullet.
The M2 can turn its target’s skeleton into a shotgun blast taking place inside their body. The harder the bone that takes the hit, the more energy is imparted to the skeleton before the bone breaks. On really hard bones, like the hip socket, the huge, fast-moving round can leave all or most of its energy in the bone and connected flesh.
This will basically liquefy the enemy it hits as the energy travels through the nearby muscles and the organs in the abdominal cavity. There’s really no way to survive a .50-cal. round if it hits a good, hard, well-connected bone. Not that your chances are much better if it hits anything but an extremity.
In fact, the .50-cal. hits with so much energy that it would likely kill you even if your body armor could stop it. The impact of the armor plate hitting your rib cage would be like taking a hit from Thor’s Hammer. That energy would still crush your organs and break apart your blood vessels and arteries, it would just allow your skin to keep most of the goop inside as you died. No laceration or cavitation, but so much crushing and shock wave that it wouldn’t matter.
So, try to avoid enemy .50-cal. rounds if you can, but rest confident in the effects on the enemy if you’re firing it at them. The ammo cans might be super heavy, but causing these kinds of effects at over a mile is often worth it.
