In 2011, the U.S. government spent about $718 billion on defense. That’s nearly half of all military spending on the planet. The other top 13 nations combined spent $695 billion.
While the yearly budget is spread out according to defense needs, some projects take the lion share. Case in point are weapon systems like the Virginia Class Submarine with a procurement cost of $76.6 billion and the V-22 Osprey at $95.2 billion. Although costly, they aren’t the most expensive military mega-projects of all time. Here’s the list:
1. Nazi Germany’s Atlantic Wall
Final cost: unknown
Although the final cost was never determined, the French portion alone would have cost $200 billion when adjusted for inflation.
Not every country in the world can afford to buy and operate the latest and greatest armored war machines available on defense markets today, like the M1A2 Abrams or the Leopard 2 main battle tanks.
Some countries opt to refrain from maintaining a fleet of tanks at all, and others, like Paraguay, choose to use refurbished armored steeds from conflicts long past.
As crazy as it may sound, the backbone of the Paraguayan military’s sole armored squadron consists of a humble handful of M4 Sherman medium tanks and M3 Stuart light tanks. Both of these vehicles were last fully relevant when Allied forces marched across Europe on their path to victory against the Axis scourge.
Paraguay received its small complement of Shermans in 1980 from Argentina, while the Stuarts were donated by the Brazilian government in the 1970s. By the time the small South American nation received these second-hand vehicles, however, they were already obsolete and outclassed, unable to stand up to anti-tank weaponry or even other armored vehicles anymore.
But in recent years, the Paraguayan army has decided to reactivate its fleet of Shermans and Stuarts, “modernizing” them by installing new engines and replacing the M4’s small battery of .30 caliber Browning M1919 medium machine guns with .50 caliber M2 ‘Ma Deuce’ heavy machine guns.
The Sherman was born of a need for a medium-sized tank that was easy to mass produce and deploy overseas in large numbers, swarming larger and more heavily-armored German tanks during WWII. Cheap to produce, and pretty reliable if treated well, the Sherman was a fairly potent killing machine in the hands of tank commanders who knew what they were doing.
The Argentinian military received 450 Shermans from Belgium in the 1940s, putting them through a series of upgrades over the next 30 years that would see these old tanks get larger guns and new diesel engines. A small selection of these Shermans were passed on to Paraguay, though it’s unclear whether or not the examples donated were modernized or left in their original configurations.
According to Ian Hogg in his book, “Tank Killing,” the Stuart, wasn’t exactly very effective at all in engaging German armor. Though it was one of the few light tanks capable of firing high-explosive shells, it was better utilized as a high speed reconnaissance vehicle by British forces throughout the African theater during WWII, with its turret removed to cut down on weight.
Brazil picked up its Stuarts from the United States in WWII, actually shipping them overseas for combat in Italy as part of the Brazilian Expeditionary Force. Upon the end of the war, these tanks were returned to South America by ship and were upgraded in the 1970s. During that decade, Brazil donated 15 Stuarts to Paraguay.
Paraguay can afford to use these older machines in place of newer heavy tanks mostly because the country hasn’t seen much war over the past 40-odd years. Currently, the military claims these modernized Shermans and Stuarts will only be used for training purposes, though the endgame of the training is highly suspect, considering that the vehicles in question aren’t fit for combat against a decently-armed enemy.
It is possible, however, that these old fighting machines could be eventually used in the long-standing counterinsurgency effort Paraguay has been embroiled in against guerrillas since 2005. Though their hulls would likely be easily destroyed by small anti-tank weapons like the M72 LAW, the armor would still be able to stand up to small arms like pistols and rifles.
Even if Paraguay never uses its tanks in combat, its geriatric fleet will still work in a pinch should the need arise — at least against unarmored and under-gunned enemies.
Okay, you’ve heard all the complaints about the F-35. It’s super-expensive. It’s got problems getting ready for combat. But in the real world, there’s no other option. And as WATM has already explained, the Marine Corps desperately needs to replace its F/A-18 Hornets.
But suppose, instead of blowing their RD money on the F-35, the Air Force, Navy, and Marines had decided to pull out File A56-7W and instead replicate Airwolf? They’d have gotten a much better deal – and it might even have helped the Army, too.
Airwolf’s specs (click here for another source) reveal this helicopter already took advantage of some stealth technology, had modern ECM systems and sensors, and very heavy armament (four 30mm cannon, two 40mm cannon, and various air-to-air and air-to-ground missiles). All in all, it’s very powerful, even if it was the brainchild of one of the big TV showrunners of the 1980s and 1990s.
So, why does it beat the F-35? Here are some of the reasons.
1. It can operate off any ship
With a top speed of over Mach 2, Airwolf may have the performance of a fighter jet, but it takes off and lands like a helicopter – without the need for the complex mechanisms used on the V-22 Osprey.
Think of it this way; with Airwolf in its hanger deck every surface combatant and amphibious ship could carry what amounts to a Generation 4.5 fighter. Even the Littoral Combat Ships could handle Airwolf, giving them a lot more punch in a fight than they currently have.
2. It would replace more airframes than the F-35 would
The F-35 is replacing the AV-8B Harrier, F/A-18 Hornet, F-16 Fighting Falcon, and A-10 Thunderbolt II in U.S. service. Airwolf not only would replace all four of those airframes, but it would also replace all of the AH-1 and AH-64 helicopters in Marine Corps and Army service. The promise of the TFX program as originally envisioned in the 1960s could be fulfilled at last!
3. Better performance
According to an Air Force fact sheet, the F-35 has a top speed of Mach 1.6, a ceiling of 50,000 feet, and a range of 1,350 miles without refueling. Airwolf hits a top speed of Mach 2, a ceiling of 100,000 feet, and a range of 1,450 miles.
In other words, Airwolf would have the F-35 beat in some crucial areas. Now, the F-35 might have an advantage in terms of payload (fixed-wing planes usually have that edge), but the fact remains, Airwolf would have been a very viable candidate for that competition – and might have had the edge, given that the Army would have bought airframes to replace the Apache.
Oh, and here’s the Season 1 opener, just for kicks:
In 1967, the Space Race was in full swing. The Soviet Union had made a number of historic firsts, but the United States was racing to catch up while making a few firsts of its own.
President Kennedy had challenged America to put a man on the moon within the decade. Long after his death, the memory of that challenge was fresh in the minds of everyone, especially those in the U.S. government who were working hard to make that happen. These include agencies such as NASA, the U.S. military and, not surprisingly, the Central Intelligence Agency.
But the United States wasn’t always so close to winning. In fact, for a time, it appeared to be behind — way behind. So far behind, in fact, the Americans were willing to do anything to catch up, even if that meant stealing the Soviet technology.
Declassified CIA documents describe their initial efforts to do just that. While they never conclusively stole Soviet space technology outright, they did have to make a huge effort to get some time alone with the tech.
Many people know about Sputnik, the first man-made satellite in orbit. Not many others know about Luna (sometimes called Lunik), the first man-made satellite to hit the moon’s surface. Both successful missions took place in 1959. And the Soviets did what any superpower looking to dunk on their Cold War rival would do: they took a victory lap.
The USSR sent Sputnik and Luna on a world tour that included stops in the United States. The U.S. was losing the Space Race because the Soviets had better booster and rocket technology than they did. So the CIA decided it would learn everything it could about Soviet space tech through the traveling showcase.
Specifically, the U.S. wanted a detailed look at the USSR’s upper stage. Most in the CIA assumed the Soviets weren’t bold enough to bring an actual Luna on a world tour for everyone to see, but there were some who realized the USSR really had brought the real thing. One night, after the traveling exhibition was closed, CIA operatives gained access to the room. They discovered it really was an actual Luna module and the lone Soviet guard had disappeared.
The CIA spent a full 24 hours with the Luna, taking what information they could with them, but they wanted more. They wanted to get inside of it. That’s when they concocted a complex, almost absurd scheme that would have been stupid – if it hadn’t worked.
That’s when they hatched a plan to steal Luna, get into it, and return the device before it could be found. They knew it usually had a large guard force posted as sentries at almost all times. They needed to get to it when the guard force was at its lowest number and find a way to get to it when no one would miss it.
The operatives discovered that the Luna went unguarded when moving by train. A guard checked its crate in at the platform, but he didn’t know what was in each of the crates and there was no expected delivery time for its arrival at the show’s next stop.
CIA agents arranged for the Luna to be on the last truck out of an exhibition. When it was on the way, other CIA operatives tailed the truck, looking for when the Soviet guards rejoined their precious cargo. But the Soviets never came. The CIA stopped the truck driver and “held him in a hotel overnight” (the documents don’t mention how he was enticed (booze, guns or prostitutes were likely involved).
With the driver safely dispatched, the truck was parked in a salvage yard and covered up. At the rail yard, the lone guard there didn’t even know the last truck was expected and he knocked off for the night, none the wiser. The CIA kept a tail on him too, just to make sure he didn’t come to work early.
Back at the truck, CIA officers dismantled and photographed the Luna in detail, working through the night to get everything documented so that the Soviet booster technology could be analyzed.
They sealed everything back together, closed the crate and put the original truck driver back on the job. When the rail yard guard checked the crate onto the train in the morning, he suspected nothing and the secret Soviet space technology was on its way to the next stop.
As a parent of a child with allergies, I am forever grateful for this one. The auto-injector apparatus was first invented for the military in the early 70’s, as a means to deliver a temporary reprieve from side effects of nerve gas exposure, during a time when the threat of chemical warfare seemed imminent.
At the request of the Pentagon, Sheldon Kaplan, a scientist with Survival Technology Inc., is credited with developing the Nerve Agent Antidote Kit, which works similarly to the EpiPen we use now, and was specifically designed to be easy to use with little training. Shortly after its effectiveness and importance in the military was discovered, Kaplan then went on to make it something that would aid the civilian world as well, by turning it into the lifesaving tools used by many with anaphylactic allergies today.
Mainstream technology has grown by leaps and bounds in a very short period of time. I remember going on family vacations and having to pull off to the side of the road so my dad could put out the map to make sure we were going the right way (and then take another 20 minutes to fold it back up again).
These days, you can get directions to virtually anywhere in the world in less than 30 seconds, all from your phone. GPS devices went from being an expensive luxury to being a built in facet of people’s lives.
While the military use of satellites and tracking goes back to the time of Sputnik, the more recognizable version of GPS was launched by the military in 1978, and was known as the Navigation System with Timing and Ranging (NAVSTAR) satellite. Taking a note from Navy scientists, this system proved to be the start of the type of navigation system the DoD was looking for in an effort to improve military intelligence.
The savior of 2 a.m. leftovers, microwaves were actually the product of accidental science. This one wasn’t necessarily invented FOR the military, but it was discovered thanks to already existing military technology.
In 1945, scientist Percy Spencer had been experimenting with and testing U.S. Army radar transmitters, when he discovered that due to the heat they produced, a candy bar in his pocket had melted. From there, the first patent on the microwave was filed within the year, and no one ever had to worry about accidentally microwaving their Hershey bars ever again.
Duct tape was born out of wartime need and a mother’s ingenuity. In 1943, Vesta Stoudt was the mother of 2 sons in the U.S. Navy, and was also employed by the Green River Ordinance Plant, where she was responsible for inspecting and packing ammunition and other tactical gear.
It was here that she noticed discrepancies and potentially dangerous issues with the ways that ammunition boxes were being packed and sealed. Originally, they were sealed with paper tape and then dipped in wax in order to ensure they were waterproof. The problem came from the tabs meant to open the boxes, which were made from the same paper tape used to seal the boxes.
In instances of trying to open these boxes while under fire, it became apparent that this not only wasted time (as the paper tabs ripped prior to opening the box) but it put service members at risk and in a vulnerable position. Stoudt came up with the idea of using waterproof cloth tape, instead of paper, making duct tape a solution that was literally invented for military purposes.
After receiving little to no feedback from those she was employed by, she decided to write to the President, Franklin D. Roosevelt. Not only did the letter include her thoughts on the current problem, she also provided her outline for a solution and detailed diagrams. The idea was passed on to Johnson Johnson, who manufactured the first version of the tape we all know, love and use today.
There are a few different stories as to how and why wristwatches came to be so popular, but they all have roots within the military.
By most accounts, wristwatches, or at least the idea of them, predate the mainstream and military usage of them, but on a very small scale. It’s said that Elizabeth I was the first of her kind to keep a small clock strapped to her wrist, while men prior to WWI still relied on pocket watches to tell time. Unsurprisingly, pocket watches did not make for the most effective tools to use in a combat setting, and since timing is such an important aspect of military strategizing, service members needed an easier way to keep track of it.
The prevalence of more user friendly time pieces skyrocketed and became commonplace. The first version, called trench watches, combined the best of both the pocket watch and wristwatch worlds, and advancement of the look, features and versatility of them still serve military members to this day.
The US Marine Corps plans to arm its forces with a new anti-ship missile that will allow US troops to sink enemy ships from shore-based launchers 100 miles away, a capability the Marines have been chasing with China’s growing navy in mind.
The Corps has decided to spend roughly $48 million on Raytheon’s Naval Strike Missile, a long-range precision strike missile the Navy ordered last year for its littoral combat ships and future frigates, Raytheon announced this week.
The service has made fielding this capability a priority.
“There’s a ground component to the maritime fight. You have to help the ships control sea space. And you can do that from the land,” Commandant of the Marine Corps Gen. Robert Neller told USNI News earlier this year. “We’ve got to be able to attack surface platforms at range.”
Breaking Defense reported in January 2019 that the Marines were considering Lockheed Martin’s Long-Range Anti-Ship Missile, the Naval Strike Missile, and Boeing’s Harpoon as options for the kind of capability the Corps desires as the US military readies itself to defeat a powerful rival like Russia or China.

The Naval Strike Missile, which was manufactured by Norway’s Kongsberg Defence Systems in partnership with Raytheon, carries a 275-pound warhead, has a range of over 100 nautical miles, and can be fired from ships and mobile shore-based launchers.
The Army experimented with a land-based launch of the Naval Strike Missile during last year’s Rim of the Pacific exercise, when the weapon was fired from a truck at a decommissioned ship off Hawaii.
The Marines have yet to select a suitable mobile launch platform, which could be Lockheed’s M142 High Mobility Artillery Rocket System or one of two large, heavy trucks from Oshkosh, Breaking Defense previously reported. The Corps told Military.com two years ago they wanted a launcher that could be easily moved by a V-22 Osprey.
The Corps still has some important experimentation and decision-making to do before the Naval Strike Missile can be effectively fielded from shore-based batteries.

The U.S. Navy awarded Demonstration of Existing Technologies (DET) contracts Oct. 25, 2018, valued at approximately $36 million each to L3 Technologies Communications Systems West and Northrop Grumman Corp. Mission Systems in support of the Next Generation Jammer Low Band (NGJ-LB) capability.
The Airborne Electronic Attack (AEA) Systems and EA-6B Program Office (PMA-234) headquartered here manages the NGJ-LB program.
NGJ-LB is an external jamming pod that is part of a larger NGJ weapon system that will augment and, ultimately, replace the aging ALQ-99 Tactical Jamming System currently in use on EA-18G Growler aircraft.

“NGJ-LB is a critical piece of the overall NGJ system in that it focuses on the denial, degradation, deception, and disruption of our adversaries’ abilities to gain an advantage in that portion of the electromagnetic spectrum,” said Capt. Michael Orr, PMA-234 program manager. “It delivers to the warfighter significant improvements in power, advanced jamming techniques, and jamming effectiveness over the legacy ALQ-99 system.”
Each DET contract has a 20-month period of performance, during which the NGJ-LB team will assess the technological maturity of the industry partners’ existing technologies in order to inform future NGJ-LB capability development, as well as define the NGJ-LB acquisition strategy.
PMA-234 is responsible for acquiring, delivering and sustaining AEA systems and EA-6B Prowler aircraft, providing combatant commanders with capabilities that enable mission success.
It’s official: the U.S. Air Force will call its new HH-60W combat rescue helicopter the “Jolly Green II.”
Standing alongside combat-search-and-rescue pilots from past and current conflicts, Air Force Secretary Barbara Barrett made the announcement during the opening of the Air Warfare Symposium in Orlando, Florida, Thursday.
“Reviving the Jolly Green name honors our combat search and rescue crews past and present,” Barrett said on social media following her speech. “In the hands of our airmen, the HH-60W ensures the rescue community can perform their duties better than ever,” she said.
The longstanding motto of the rescue community is, “These things we do that others may live.” The name Jolly Green — which the CSAR community has adopted as its trademark alongside green feet stamps on the aircraft — dates back to the Vietnam War era when American pilots flew the HH-3E.
While pilots today will stamp the sides of the helicopter with green feet to commemorate their own missions, the origin of the green feet is a nod to the HH-3E helicopter, also known as the Jolly Green Giant, which left fat imprints when landing in Vietnam’s rice patties and grass fields, according to the service.
Air Force Chief of Staff Gen David Goldfein on Thursday stressed the service’s need for HH-60W, especially given his own experience. As a lieutenant colonel, Goldfein was shot down in his F-16CJ fighter jet over Serbia in 1999 during the NATO bombing of Yugoslavia, and subsequently rescued by CSAR units.
“The Jolly Green gives us extended range and better capability,” Goldfein said on Twitter following the announcement. “I was grateful for a ride out of enemy territory when I needed it and I can tell you first-hand that this aircraft will save lives.”
In July, the service began its first tests of the Lockheed Martin-Sikorsky-made HH-60W — based on the UH-60M Black Hawk — which is meant to replace its current HH-60G Pave Hawk fleet. Its missions also include “civil search and rescue, medical evacuation, disaster response, humanitarian assistance, security cooperation/aviation advisory, NASA space flight support and CSAR command and control,” the service said.
Current 1980s-era HH-60G models are capable of flying low, and have a retractable in-flight refueling probe and internal auxiliary fuel tanks that allow for better range and loiter time during rescue missions.
The HH-60W doubles the internal fuel capacity without using the auxiliary fuel tanks, and also increases the flight hours. The aircraft also has improved avionics, navigation, communications and an enhanced software network, plus better defensive measures and armored plating, according to the company.
Through its fiscal 2019 and 2020 budgets, Congress gave the Air Force the authority to procure 22 of the Jolly Green II. The first two units to be fielded with the aircraft will be the 41st Rescue Squadron at Moody Air Force Base, Georgia, and the 512th Rescue Squadron at Kirtland Air Force Base, New Mexico, officials said.
The service plans to purchase up to 113 of the rotary-wing aircraft.
The SR-71 Blackbird is an awesome plane. But did you know that it could have been even more awesome than it was? The Air Force was planning to make a fighter version of the plane.
Aviation historian Joe Baugher notes that as the early iterations of the SR-71 were being designed, there was a need for an interceptor. The F-108 program had been cancelled due to its high cost. However, there was still a desire for a high-speed, long-range interceptor.
The A-12 OXCART being developed for the CIA was seen as a likely basis for a fighter. Lockheed’s Skunk Works team soon figured out how to add a powerful radar, the AN/ASG-18, capable of detecting targets from as far off as 500 miles in some cases, and four AIM-47 missiles.
The resulting plane was designated the YF-12, and three prototypes were built.
Designation-Systems.net notes that the AIM-47 had a range of over 100 miles and a speed of Mach 4. While a 250-ton W42 warhead never materialized for this missile, it did get a 100-pound high-explosive warhead.
News of the the YF-12’s development was leaked in an effort to distract the public from the work being done to make a reconnaissance plane. But the plane – awesome as it was – would not ever see service due to the development of reliable inter-continental ballistic missiles.
The YF-12 would get a production order for 93 airframes from the Air Force. However, then-Secretary of Defense Robert McNamara refused to release the funds, and the project ended up being halted at the three prototypes. Two were handed over to NASA for research flights. One of those crashed after a fuel line caught fire in 1971, with the crew ejecting from the stricken plane.
The YF-12 will remain one of the biggest “could have been” planes in history. The jet still has a legacy – partially in the SR-71 Blackbird, but also in the form of the AWG-9 radar and AIM-54 Phoenix missiles used by the F-14 Tomcat. Even though this plane never got a chance to serve, it still did a lot for America’s military aviation development.
Some people go skydiving or do other extreme sports to get their adrenaline fix. Troops, on the other hand, get into gunfights. Celebrated war correspondent, Sebastian Junger nails this phenomenon in his 2014 Ted talk about why soldiers miss war.
While thrilling, the downside to any gunfight is getting shot. This video reveals five random facts about gunshot wounds you probably didn’t know. (For instance, did you know that women are more likely to survive than men? What does that do to your “women in combat” matrix?)
There is a proverbial 800-pound gorilla that the United States Army is facing. Well, more like 110 pounds. That’s the weight some soldiers have to haul on their backs. And it’s a big problem.
“We [now] have Soldiers in their late teens and early 20s and they’re getting broken sometimes in training before they see a day in combat,” Zac Wingard, a mechanical engineer for the Army Research Laboratory’s Weapons and Materials Research Directorate, was quoted in an Army release as saying during the Association of the United States Army’s Global Force Symposium.
How to prevent this? One solution is to give the troops a third arm. Yeah, you read that right. The Army Research Lab has a prototype third arm for troops that will hang off their body armor.
The device, which weighs about 4 pounds, is currently in testing at the Aberdeen Proving Grounds. Currently, the third arm is being used to help re-direct the weight of weapons, currently M4 carbines, onto a soldier’s body.
“With this configuration right now, we can go up to 20 pounds and take all of that weight off of the arms,” mechanical engineer Dan Baechle said.
During the testing, troops have been wearing sensors to determine how much muscle activity is occurring. Eventually this system could be used with other weapons, like the M249 Squad Automatic Weapon or the M240B machine gun. But it might not end there – troops could be able to carry more powerful systems, since the recoil won’t be directly impacting them.
“We could potentially look at very high recoil systems that aren’t going to beat up on the soldier like they normally would,” Baechle said. There are also application for other tactical needs, like shooting around corners, close-quarters combat, and other fighting techniques.
But it might not just be about helping to shoot a weapon. Troops could also use the third arm to hold shields or keep a weapon ready while using other tools to breach barricades.
That said, before this system goes into the field, they will try to make sure it can be rugged enough to handle whatever the battlefield throws at it.
The National Aeronautical and Space Administration has done very well with their small force of WB-57 Canberra reconnaissance planes. These planes have flown for nearly 60 years and they continue to serve today. With such a long, storied history, it’s easy to forget why the B-57 came to be in the first place. Let’s stroll down memory lane.
Originally, the B-57 Canberra was designed to be a light bomber that used high performance to avoid interception. The British started development of this plane in the latter years of World War II. While the American-produced versions did see some use as bombers during the Vietnam War, the Canberra truly hit its stride as a high-altitude reconnaissance asset for the Air Force.
The RB-57D Canberra variant was designed specifically for high-altitude recon missions.
The RB-57A was the first adaptation of the Canberra designed specifically for reconnaissance work, but the RB-57D was the first such plane intended to do so at high altitudes. Three versions of this recon jet were developed: One was for photo-reconnaissance, using advanced (for the time) camera, a second for electronic warfare, and a third that packed a powerful radar for mapping the ground.
The RB-57F, a much later version, which was created from re-manufacturing older Canberras. These souped-up planes featured more powerful engines and longer wings. They were able to operate at higher altitudes and were used for weather reconnaissance and to collect samples from nuclear tests.
This RB-57 started its life in the Air Force, and now flies with NASA as plane number 926.
Today, NASA still operates three B-57 Canberras. Whiles Canberras have now retired, a few are still flying in civilian hands, undertaking mapping missions.
Watch to video below to learn how the RB-57D was introduced to the United States.
The Blackhawks are one of the lesser-known superheroes in the DC Comics pantheon today, but from the 1940s to the 1960s, they were big names. The only hero who outsold them during the early years of their run was Superman.
Part of the appeal was their planes. In the 1950s, their primary mount was the Lockheed F-90, which they used to fight off their monster and alien foes.
But here’s the kicker – the plane they flew has some origin in fact, but it never got past the flight test stage.
Dubbed the “XF-90,” the experimental plane’s tale is one of the few real failures that came from Lockheed’s legendary Skunk Works.
According to aviation historian Joe Baugher, the Air Force was looking for a long-range jet fighter to escort bombers to targets. Lockheed went with the F-90, and proceeded to build it in a very sturdy fashion.
The good news was that this was one tough plane, and had six 20mm cannon (enough to blast just about any plane out of the sky), but it weighed 50 percent more than its competitor, the XF-88 Voodoo from McDonnell.
From the get-go, the XF-90 had problems. The plane was underpowered and was outperformed by the F-86A — even when afterburners were added to the plane’s two XJ34 jet engines. The Air Force chose the XF-88 Voodoo to be its penetration fighter, but that never went into production.
Only two XF-90s were built.
Lockheed had tried a number of other options, including the use of a single J47 engine to boost the F-90s performance, but there was too much re-design work involved. The first F-90 version the Blackhawks used, the F-90B, did feature a single engine. The second version, the F-90C, was said to be lighter version of the F-90B.
The Blackhawks eventually faded — partially due to some bad 1960s storylines — and the super hero team was eventually eclipsed by Batman and many of the superheroes who are familiar today.
And as for the XF-90 prototypes? One was tested to destruction by the National Advisory Committee for Aeronautics, and the other was banged up in the nuclear tests of the 1950s.
That second plane is currently in storage at the National Museum of the United States Air Force in Dayton, Ohio.
