Often, these grenades were used on single-shot systems like the M79 or the M203. But soon, automatic grenade launchers were developed. One that became iconic was the Mk-19 automatic grenade launcher. With a range of 1,500 yards, it could fire a grenade a second, and it weighs nearly 73 pounds. The Mk-19 is in service with 23 countries.
That said, it is getting long in the tooth. It entered service in 1967, so it’s been around for 50 years. That means that it’s about time to think about a replacement. According to General Dynamics that replacement may be available.
The Mk-47 Mod 0 40mm Advanced Grenade Launcher fires the same grenades as the Mk-19, but it also comes with a lot of advances to make it deadlier. One that the grunts will like is the weight: it comes in at just under 40 pounds – 32 pounds less than the Mk 19. The system also adds a new video sight that adds laser ranger-finding and night vision, allowing for better target acquisition.
Perhaps the deadliest accessory for the Mk-47 is the Mk-285 grenade. This is airburst ammunition, much like the 25mm rounds fired by the XM25 Punisher. How does it know when to airburst? It’s programmed with data from the advanced sight.
This new automatic grenade launcher may prove to be more popular than the new Carl that Saab released among American troops and their allies. The bad guys probably won’t like it very much, but who really cares what they think?
Joe Serna escaped death so many times while deployed with the Army’s Special Forces. He was blown up by explosive devices on multiple occasions over three combat deployments to Afghanistan. One threw him from his vehicle, another nearly drowned him in an MRAP in an irrigation canal, and a Taliban fighter detonated a grenade in his face. Like many combat veterans of his caliber, both mental and physical wounds followed him home.
After his medical retirement, alcohol-related events landed him in hot water with the law until the day he violated his probation and ended up in front of North Carolina Judge Lou Olivera.
Serna’s MRAP was thrown into a canal by an IED in 2008. Three other soldiers drowned, including one who rescued Serna.
In 2016, Serna’s record of offenses and failure to follow his probation put him in front of a North Carolina Veterans Treatment Court, a system of justice designed to hold returning veterans accountable for their behavior while accepting the special set of circumstances they might be struggling with in their daily life. Veterans Treatment Courts demand mandatory appearances, drug and alcohol testing, and a structure similar to the demands of the service.
Judge Lou Olivera was presiding over Cumberland County, North Carolina’s veterans treatment courts. Olivera is a veteran of the Gulf War and is especially suited to handle cases like Serna’s. The judge ordered the green beret to spend 24 hours in jail for his probation violation, not anything unusual for a judge to do. What Olivera did next is what makes his court exceptional.
Olivera convinced Serna’s jailer, also a veteran, to allow the judge to share Serna’s sentence. Judge Olivera was volunteering to be a battle buddy for the green beret while he did his time. The judge drove Serna to the neighboring county lockup, where jail administrator George Kenworthy put them both in jail for the night.
“He did his duty,” Serna told People Magazine. “He sentenced me. It was his job to hold me accountable. He is a judge, but that night he was my battle buddy. He knew what I was going through. As a warrior, he connected.”
Serna had no idea Judge Olivera planned to share his sentence as the two drove to the Robeson County, N.C. jail. Olivera knew of Serna’s combat records, and that the green beret spent a night in a submerged in an MRAP, struggling to stay in an air pocket, with the bodies of his drowned compatriots around him. So a night spent in a cramped box seemed like a harsh sentence that could trigger harsher thoughts, but the judge knew the soldier had to be held accountable. So he decided he wouldn’t be alone in the box.
“Joe was a good soldier, and he’s a good man,” Olivera said. “I wanted him to know I had his back. I didn’t want him to do this alone… I’m a judge and I’ve seen evil, but I see the humanity in people. Joe is a good man. Helping him helped me. I wanted him to know he isn’t alone.”
The SR-71 Blackbird is the arguably the most popular and easily recognizable airframe ever used by the U.S. Air Force. It maintains the speed record it set back in 1976 (even with a broken engine). The Blackbird’s missile evasion technique is legendary; it simply flew faster than the whatever was chasing it.
Not one SR-71 was ever shot down.
It could take a full photo of the entire country of North Korea in seven minutes and fly across the entire United States, lengthwise, in just over an hour.
Not bad, but that capability didn’t happen overnight. The Air Force actually developed more than one supersonic plane for its reconnaissance and strike missions.
1. XB-70 Valkyrie
Only 2 of North American Aviation’s B-70 bombers were ever built, and the program only lasted for the five years between 1964 and 1969. The Valkyrie was a six-engine bomber, capable of flying Mach 3, designed to outrun enemy interceptor aircraft with speed and altitude. At the time, interception was the only defense against bombers.
Surface-to-air missiles changed the game.
The XB-70 was still fast enough to fool radar, but its limited range and expense made the B-52 a more economically efficient choice for production. Though short-lived, the Valkyrie did blaze a trail for the structural dynamics that would be so crucial to the SR-71.
Not to be confused with the later naval stealth fighter proposal dubbed the A-12 Avenger II, the A-12 Archangel was a recon aircraft developed by Lockheed for the CIA between 1962 and 1967. The defense giant’s “Skunk Works,” the nickname given to its Advanced Development Programs department, developed the A-12 for the CIA’s Oxcart Operation.
Oxcart was the agency’s effort to replace the U-2 spy plane after it became increasingly susceptible to Soviet SAMs. They were wildly successful – the planes boasted a host of new technologies designed just for the program. They were built with titanium to handle hypersonic speeds (strangely obtained from the Soviet Union).
Though designed to fly over Cuba and the USSR, the Lockheed A-12 never executed that mission. It flew over North Vietnam and North Korea during the Pueblo Crisis.
The North Vietnamese were able to track the A-12 via radar, and routinely launched missiles at it. It never took a direct hit from a SAM but did get debris from an exploding missile lodged in its fuselage.
Since the A-12 was never going to fly over the Soviet Union and the use of satellite photography was on the rise, the program was scrapped almost as soon as it had begun. The A-12s were either stored in Palmdale, California, or sent to museums.
The M-21 variant of the A-12 was designed to carry the Lockheed D-12 Drone. This variation had a cockpit for the drone’s launch control officer who released the autonomous drone which was mounted on the back of the M-21 airframe.
The D-21 was launched from the back of the A-12. Once its mission was complete, the drone would eject the data it collected at a preprogrammed point and then self-destruct. The ejected data was caught in mid-air by a C-130.
This program was canceled in 1966 when a drone collided in midair with its launcher. The M-21 crew all bailed out, except for the LCO. From then on, the D-21 would be launched from under the wing of a B-52.
4. Lockheed YF-12
The YF-12 was a twin-seat version of the A-12. Designed to be an interceptor, the YF-12 set the speed records that would only be surpassed by the legendary SR-71. It also has the distinction of being a publicly announced aircraft, which had benefits of keeping the A-12 a secret because the public couldn’t tell the difference.
The cost of the Vietnam War kept the YF-12 from the Air Force inventory. And by the time the funds were available, the YF-12 wasn’t necessary to defend the mainland U.S., so the program was scrapped.
The aircraft did successfully test the AIM-47 Falcon missile, which was the predecessor to the Phoenix missiles. The YF-12 also tested how AWACS could command bombers in a tactical environment, which later helped the development of the B-1 Bomber.
The YF-12 also tested how engine inlet performance affected airframe for NASA, as well as issues related to propulsion interaction, boundary layer noise, heat transfer under high-mach conditions, and altitude hold at supersonic speeds – all necessary to develop the SR-71, not to mention the Space Shuttle program.
The problems the Marine Corps is having with its F/A-18 Hornet force have been a boon to one plane that was originally slated to go to the boneyard much earlier.
According to Foxtrot Alpha, the AV-8B Harrier has recently gained a new lease on life as upgrades are keeping the famed “jump jet” in service. In fact, the Harrier force has become more reliable in recent years, even as it too sees the effects of aging.
The Marine Corps is planning to replace both the F/A-18C/D Hornets and the AV-8B Harriers with the F-35B Lightning II, the Vertical/Short Take-Off and Landing version of the Joint Strike Fighter. The F-35B has already been deployed to Japan, while the F-35A, operating from conventional land bases, just recently deployed to Estonia.
Originally, the Harriers were slated to be retired first, but the delays on the F-35 and a review that not only changed how the Marines used the Harrier, but also discovered that the Harrier airframes had far more flight hours left in the than originally thought gave them a new lease on life.
As a result, the Marines pushed through upgrades for the Harrier force, including newer AMRAAM missiles and the GBU-54 Laser Joint Direct Attack Munition, a 500-pound system that combined both GPS guidance with a laser seeker. Other upgrades will keep the Harriers flying well into the 2020s.

The Harrier has been a Marine Corps mainstay since 1971 – often providing the close-air support for Marines in combat through Desert Storm and the War on Terror. The Harrier and Sea Harrier first made their mark in the Falklands War, where the jump jets helped the United Kingdom liberate the disputed islands after Argentinean military forces invaded.
When ships deploy out to sea, it’s important they bring the fuel and spare parts they need. The ship’s crew also needs to be supplied. While food is often transferred to these ships, there’s also the pressing need for the crew to drink.
Although they’re surrounded by water, the ocean upon which these ships float isn’t exactly the best thing to drink. The National Oceanic and Atmospheric Administration points out that if you drink sea water, you get more dehydrated and, ultimately, dehydration kills people. Drinking seawater brings about other health problems that can cause problems on board ship, specifically the head.
It used to be that ships had to carry water that was safe for drinking. This made crossing oceans difficult to say the least. The sailing frigate USS Constitution (ex-IX 21), one of the original six frigates built for the United States Navy, had a crew of 450. Humans need to drink nearly a gallon of water a day, according to the Mayo Clinic, which, as you can imagine, meant carrying a lot of fresh water as cargo.
Well, today, making sure the sailors have plenty of fresh water for all their needs is much easier. The Navy can do this thanks to the Light Weight Purification System. It just takes one sailor to operate, and it can handle anything from sea water to fresh water. According to a Marine Corps document, this system can purify 75 gallons of water per hour.
The Navy, of course, has other systems that can handle larger amounts, but the Light Weight Purification System is very mobile, which becomes very useful for Marines on the front lines. Learn more about this system in the video below:
During the Cold War, the Soviets exploited the ground effect phenomenon by creating some of the largest and fastest vehicles of the time called “Ekranoplans.” They were not quite airplanes or hovercraft but something else in between known as Ground Effect Vehicles (GEVs).
Although the technology already existed, they took it to the next level by scaling these vehicles to three-quarters of a football field, weighing more than 350 tons and traveling at speeds beyond 400 miles per hour.
The technology was reportedly used from 1987 to the late 1990s. There was a transport version, a battle version, and even a hospital version of the Ekranoplan. The last of its kind was 90 percent complete when funding ran out. It now sits unused at a naval station in Kaspiysk off the Caspian Sea.
Today, the ground effect technology is making a come back in small hobby vehicles and glorified water taxis. GEVs are fuel and power efficient and become even more economical as they get bigger, according to the video below. “In theory, wing in ground effect works better as the craft gets bigger, so a really big craft would be very, very efficient. That’s where the economics starts to make sense and you can start to build a business out of it.”
This video shows how ground effect technology is making a comeback decades since the Cold War.
Watch the video in the tweet below. Are you experiencing both amazement and fear? You’re not alone.
This video has been making the rounds on Twitter recently, but it was actually filmed a little over a year ago. According to Gizmodo, an electric-power maintenance company in Xiangyang, China, had been using these flame-throwing drones to burn off garbage and debris from electrical wires.
Is any of this safe? Who knows. But after watching this video, hopefully you’ve gained a new appreciation and/or fear of flying robots and what they’re capable of.
Looking almost like an oversized pistol, the Heckler Koch MP7 is a cross between a submachine gun and a carbine that serves around the world in the hands of law enforcement and special operations units.
In the late 1980s, NATO developed requirements for a next-generation personal defense weapon that would be more effective against body armor than current pistol-caliber PDWs. While submachine guns based on the .45 ACP or 9mm deliver plenty of stopping power against unarmored targets, the growing availability of capable and affordable body armor meant that something new was needed.

So German gunmaker Heckler Koch developed the MP7 to meet these NATO requirements and it has served across the world since entering full production in 2001.
Some of the most commonly-spotted submachine guns in the hands of law enforcement and other professionals are the MP5 and its successor, the UMP. These guns typify the classic submachine gun, being automatic weapons chambered for pistol cartridges.
The MP7, however, is chambered for the 4.6x30mm cartridge. The steel core 4.6x30mm was developed specifically to be a lightweight pistol-ish round delivering the penetration more like a rifle cartridge. The smaller, lighter round means that more ammunition can be carried and that it has a minimal recoil even in full-automatic shooting.
The 4.6mm cartridge was developed by HK for the MP7 and its companion sidearm, the UCP pistol. The UCP never got past the prototype stage, but the 4.6x30mm has definitely made its mark in the MP7.
The MP7, currently being produced as updated models MP7A1 and MP7A2, weighs less than 5 pounds with a loaded magazine and is only 25-inches long with its adjustable stock fully extended. The barrel is 7.1 inches long and the magazine feeds into the pistol grip, creating a compact, easy to handle package.
The action is a gas-operated short stroke piston like that of HK’s HK416 rifle and is rated at 950 rounds per minute. A folding forward vertical grip comes standard on the MP7, though this has been replaced on the new MP7A2 model with a standard lower rail which allows the user to easily install any grip if desired. A full-length top rail comes with removable folding sights and permits the mounting of any standard optic or other accessory, and side rails can be easily added for additional mounting options.
The 4.6x30mm ammunition means that magazine size is decreased compared to those holding traditional cartridges. A 40-round MP7 magazine is comparable in size to 30-round 9mm magazine like the ones in the MP5. This means more firepower ready for action and fewer mag changes, both of which can easily spell the difference between success or failure in life and death situations.
The MP7 utilizes a great deal of polymer in its construction, and the weapon’s light weight, ergonomics, and physical size allow it to be fired accurately with one hand. When the stock is extended and the forward grip used, it suddenly becomes a mini carbine with performance similar to full-sized guns as long at the range stays below 200 meters or so.
Military special forces utilize the MP7 much like they have used submachine guns for decades. Smaller, lighter weapons that can provide automatic fire are invaluable for close-quarters combat and the 4.6x30mm’s armor-piercing capability make the MP7 a natural choice for elite units needing compact firepower. The weapon’s design and tactical rails mean that the gun can be easily upgraded as needed with off the shelf accessories. Additionally, the MP7 is suppressor-ready, adding another level of utility to an already-capable gun for special operations use.
The U.S. Navy’s Naval Special Warfare Development Group, more commonly known as SEAL Team 6, is one of the most famous units that employ the MP7 in the special operations community. Many details of their equipment became known after the 2011 mission that killed Osama Bin Laden in Pakistan, and the MP7 was said to have been chosen by some of the raid’s members.
Pistols will remain common sidearms for as long as sidearms are needed. And while standard submachine guns using pistol ammunition will continue to serve a vital role for years to come and carbine-configuration assault rifles will remain the standard infantry weapon in militaries for the foreseeable future, the HK MP7 and other weapons like it will fill a crucial middle ground for those looking for the best of all worlds.
The Royal Australian Navy has long been a small force that’s able to punch above its weight. Now, they’re taking on another advanced vessel, one that could very well see service with the United State Navy in the next decade.
The vessel in question is the Hobart-class air warfare destroyer. This vessel is based on the Spanish Álvaro de Bazán-class guided missile frigate. If that Spanish vessel sounds familiar, that’s because it’s one of the contenders in the United States Navy’s FFG(X) program — a strong one, given its use of the Aegis combat system and the SPY-1 radar.
Australia’s Navy has added some Spanish flavor — their Canberra-class amphibious assault ships are based on the Spanish Navy’s sole amphibious assault vessel, the Juan Carlos I.

The Hobart-class destroyer is basically half of an Arleigh Burke-class guided missile destroyer. Its armament suite consists of a single five-inch gun, one 48-cell Mk 41 vertical launch system, two quad Mk 141 mounts for the RGM-84 Harpoon anti-ship missile, a Mk 15 Phalanx, two 25mm Bushmaster chain guns, and two twin 324mm torpedo tube mounts. The vessels can also operate a MH-60R Seahawk multi-mission helicopter. The Mk 41 can fire RIM-66 SM-2 Standard missiles, RIM-162 Evolved Sea Sparrow Missiles, RUM-139 Vertical-Launch ASROC, and BGM-109 Tomahawk cruise missiles.
The Australians have been waiting for these vessels for a while. They retired their Perth-class guided-missile destroyers in 2001. These modified Charles F. Adams-class vessels were also quite formidable. They packed two five-inch guns, a Mk 13 launcher that fired RIM-66 SM-1 Standard missiles and RGM-84 Harpoon anti-ship missiles, two Ikara launchers, and 324mm torpedo tubes.
Between the retiring of the Perth-class and the introduction of the Hobart-class, four of Australia’s Adelaide-class frigates (modified versions of the Oliver Hazard Perry-class) held the line. To do so, they were upgraded with Evolved Sea Sparrow Missiles and the SM-2.

The Australian Navy has operated closely with the United States for decades. All three Perth-class vessels saw service in Vietnam (one of which was on the receiving end of a friendly-fire incident). A Perth-class destroyer also took part in Operation Desert Storm.
The first of the Hobart-class vessels, HMAS Hobart, has been commissioned, with the second vessel, HMAS Brisbane, due this year and a third, HMAS Sydney, coming in 2019. The performance of HMAS Hobart could very well determine how the United States Navy decides to fulfill its current frigate needs.

2019-11-20 Full Committee Hearing: Legislative Hearing on HR 3495 and a Draft Bill
Brazil has had a decent aerospace industry centered on Embraer, a conglomerate that made everything from airborne radar planes to trainers. However, that industry has gotten a little too full of itself lately. They think one of their trainers can replace the A-10.
But we digress. We’re not here to cyberbully a wannabe A-10 to the point that Selena Gomez has to consider making an aviation version of 13 Reasons Why, despite how much fun it would be to really make said wannabe feel really bad about itself. Even though it should… but again, we digress.
The fact is, the P-51 Mustang could arguably fly circles around the A-29, but the A-29 makes for a decent trainer.
No, we are here to take a look at this plane, which is already giving honorable service in the fight against terrorism. It’s been dropping bombs on al-Qaeda and the Taliban for a bit. It’s in service with over 14 countries.
The Super Tucano boasts a top speed of 229 miles per hour (the P-51 Mustang could hit 437). It can carry rockets, bombs, AGM-114 Hellfire missiles, air-to-air missiles, and gun pods for use against enemy forces. The plane also boasts a maximum range of 2,995 miles. Currently, 205 Super Tucanos are in service around the world.
The United States Air Force is one of 14 countries using the Super Tucano.
While the winner of the OA-X competition has yet to be determined, the Super Tucano does have a decent track record as a trainer and light attack plane. Learn more about this Brazilian A-10 wannabe in the video below.
Air Force pararescuemen are among the elite when it comes to special operations. Their main task is to rescue pilots who have been shot down behind enemy lines. It’s never been an easy task, but at least the tech has improved since World War II. Back then, a pilot had to walk back to friendly lines – a very long walk.
Amphibious planes, like the PBY Catalina and HU-16 made rescue possible, but you needed enough water – or a strip of land – for them to land and take off. The same went for other planes, even the L-5, the military designation for the Piper Cub.
Insert the helicopter. They first appeared in a small capacity during the Korean War before they really came of age during Vietnam, proving to be the search-and-rescue asset America needed.
Here’s a look some legendary choppers that carried out that mission.
1. Sikorsky HH-3 Jolly Green Giant
The first helicopter to become a legend for search and rescue was the Sikorsky HH-3. The H-3 airframe was first designed for the Navy to carry out anti-submarine warfare, and was called the Sea King. But the size of the chopper lead the Air Force to buy some as heavy transports. They were eventually equipped with 7.62mm Miniguns and used to rescue pilots, with some seeing service in Desert Storm and the last ones serving until 1995.
According to an Air Force fact sheet, the HH-3 has a top speed of 177 miles per hour, and could carry up to 25 passengers or 15 litters, plus a crew of four and two attendants.
2. Sikorsky HH-53 Super Jolly/Pave Low
The Air Force didn’t stop with the Jolly Green. Eventually, the even larger HH-53 was procured, and called the Super Jolly Green Giant. They also took part in search-and-rescue missions during the Vietnam War, but after that war, the HH-53s were upgraded into the Pave Low configuration, making them capable of operating at night and bad weather. They also became used as special operations transports. The last Pave Lows were retired in 2008.
According to an Air Force fact sheet, the latest version of the Pave Low has a top speed of 165 miles per hour, an un-refueled range of 690 miles, and a crew of six.
3. Sikorsky HH-60G Pave Hawk
The Air Force though, was looking for more search-and-rescue assets – mostly because they only bought 41 of the Super Jolly Green Giants. The HH-60G is primarily tasked with the combat search and rescue role, and it usually carries .50-caliber machine guns to protect itself. Like the Pave Low, the Pave Hawk can carry out missions at night or day. The HH-60G is currently serving.
An Air Force fact sheet notes that a total of 99 Pave Hawks serve in the active Air Force, the Air National Guard, and Air Force Reserve. The Pave Hawk has a top speed of 184 miles per hour, an unrefueled range of 504 nautical miles, and can carry a crew of four.
4. Sikorsky HH-60W Combat Rescue Helicopter
The H-60 airframe has been a mainstay of all five armed services, so much so that the replacement for the HH-60G is another H-60. In this case, the HH-60W is a modified version of the Army’s UH-60M Blackhawk.
According to materialsprovided by Sikorsky, a division of Lockheed Martin, the HH-60W has a combat radius of 195 nautical miles, and is equipped with new displays to reduce the air crew’s workload, and to help the pararescue jumpers do their job more efficiently. The Air Force plans to buy 112 HH-60Ws to replace the 99 HH-60Gs currently in service.
In short, when a pilot goes down, the assets are now there to pull him out, and to keep him from becoming a guest in a 21st century Hanoi Hilton.
