Nazi Secret Weapons: The Rocket U-Boat?

Throughout World War II, Nazis scientists sought secret weapons to launch offensive attacks on American soil. What was the mysterious Rocket U-Boat? And how close did it come to destroying New York City?

Nazi Secret Weapons: The Rocket U-Boat?

Throughout World War II, the Nazis sought to build long-range, secret weapons (such as the Amerika-Bomber and the Sun Gun). In 1941, this desire led Nazi scientists to research the Rocket U-Boat. They hoped such a U-boat could travel across the globe, targeting cities on distant continents. In 1942, scientists developed and tested the first Rocket U-Boat. It was relatively simple, just a few rocket launchers mounted on the U-511’s deck. The test was a mixed bag. On one hand, the missiles fired just fine at depths of up to 12 meters. However, the lack of a guidance system rendered the missiles useless.

In 1943, Nazi scientists developed another secret weapon known as the V-1 flying bomb, an early predecessor to the cruise missile. It had a range of 160 miles. Paired with a U-Boat, it would be capable of long-distance strikes on any city in the world. However, the Nazi Luftwaffe showed little interest in helping to create the Rocket U-Boat, probably due to inter-service rivalry.

That same year, Nazi scientists developed another secret weapon known as the V-2 rocket. The V-2 was the world’s first long-range combat ballistic missile as well as the first rocket to achieve sub-orbital spaceflight. It had a range of 200 miles. Again, this seemed like the perfect fit for a Rocket U-Boat. And in late 1944, resources were finally allocated to it under Project Prufstand XII. The target of the Rocket U-Boat?

New York.

The Race to build a Rocket U-Boat?

The V-2 was much larger than the V-1 flying bomb. In fact, it was too large for any existing Nazi U-boat. Undeterred, Nazi scientists developed a 500-ton specially-constructed container for the V-2. The plan was to have a U-boat tow it across the Atlantic Ocean. Then sailors would flood the ballast tanks, causing the rocket to shift into a vertical position. Afterward, the sailors would fuel the rocket, prepare the guidance system, and aim it at New York.

The Nazis ordered three of these containers. At least one was actually built. It is unknown if this container was ever tested in any fashion.

Guerrilla Explorer’s Analysis

The Americans were well-aware of Nazi attempts to build a Rocket U-Boat secret weapon and prepared a contingency plan known as Operation Teardrop. In March 1945, six Nazi U-boats approached America. The U.S. launched Operation Teardrop and ended up destroying the four of the boats. It was later determined that none of these were Rocket U-Boats.

But that doesn’t mean the Rocket U-Boat was never launched. In February 1945, the U-1053 was carrying out diving trials off the coast of Norway. With all sides closing in on Nazi Germany, this seems like an odd time to worry about diving trials. Some historians think the U-1053 may have had an ulterior purpose, perhaps to test out a Rocket U-Boat system. The U-1053 shipwreck was located in March 2010. To my knowledge, it has yet to be fully explored.

The Nazi Sun Gun: Death from Above?

Nazi Germany created many unusual, horrific weapons during World War II. One incredible weapon, however, failed to materialize. What was the Nazi Sun Gun?

The Birth of the Nazi Sun Gun?

In 1929, a German physicist named Hermann Oberth wrote Wege zur Raumschiffahrt (Translation: Ways to Spaceflight). The book described Oberth’s vision of a manned orbital space station created from prefabricated parts. He also described a way to create electricity using a 100-meter wide concave mirror. The idea was to concentrate sunlight onto a single area and use steam turbines to convert the heat energy.

While Oberth’s mirror was designed to create useful energy, Nazi scientists saw another use for it. Namely, an orbital weapon called Sonnengewehr…or Sun Gun.

Launching the Sun Gun into Space

Plans for the Sun Gun were worked out by Nazi scientists at Hillersleben. They proposed creating a giant three-kilometer square mirror out of metallic sodium. Then they wanted to break it apart and launch the individual pieces into an orbit of 8,200 kilometers. In order to do this, the Nazi scientists hoped to use the Aggregate A11.

The A11 was a multistage rocket intended to deliver people and/or small payloads into low Earth orbit. At the time, it was being designed by Wernher von Braun (who later became chief architect of the Saturn V launch vehicle via Operation Paperclip, which helped land Neil Armstrong, Buzz Aldrin, and Michael Collins on the moon).

Oberth’s original plan was to send an unmanned rocket into space, containing six long cables. These cables would then unreel themselves, eventually covering a vast area. Nazi astronauts would then fly into space and attach pieces of the giant movable mirror to the cables.

How did the Sun Gun Work?

According to Life, Nazi astronauts would live inside the rocket, using large greenhouses to maintain fresh oxygen. They would remain in space, waiting for orders from radio or wireless telegraph. Upon receiving orders to attack, they would use rocket thrusters to move the mirror into position. The mirror would focus the sunlight, causing incredible devastation in the process.

Fortunately, the Sun Gun never went past the theoretical stage. In fact, newspaper articles from 1945 say it would’ve taken 50 to 100 years to harness the sun’s energy in this fashion. However, Oberth disagreed, claiming it would take just 10 to 15 years. Oberth admitted the original mirror’s design might not have worked. However, he came to believe that a larger mirror would’ve done the trick.

“If the mirror were double the size mentioned, however, the irradiation would be four times as strong, and so on. The temperature on the surface irradiated by the double-sized mirror would be 200° C (392° F).” – Hermann Oberth, Man into Space (1957)

Water boils at 212 degrees Fahrenheit. So, 392 degrees would’ve been plenty hot…perhaps hot enough to change the course of the war itself.

Telepathic Soldiers?

Not to be outdone by DARPA’s never-ending list of sci-fi projects, the U.S. Army has decided to step up its game. In the next five years, it plans to spend $4 million in taxpayer funds in order to develop real-life telepathy.

Synthetic Telepathy?

The U.S. Army’s version of telepathy is called Synthetic Telepathy. It bears some resemblance to the style of telepathy seen in the popular Metal Gear Solid 4 video game. But where Metal Gear relied on nanotechnology, this real-world telepathy relies on mind-reading.

Here’s how it works. Soldiers wear helmets containing electrodes. The electrodes read electrical activity in the brain and identify code words. Those code words are then relayed back to a central computer before being dished out to other soldiers in the field. Currently, computers are able to identify 45% of the code words. By 2017, the U.S. Army hopes that number will be closer to 100%.

Guerrilla Explorer’s Analysis

Incidentally, this project first received funding back in 2008. At the time, researchers estimated Synthetic Telepathy would take 15-20 years to develop. It appears they’ve progressed fast enough to shave 6-11 years from that original mark.

At least some soldiers seem pleased by the development. On the other end of the spectrum, civil libertarians are worried about how it could be used by governments against their own citizens. It’s difficult to say exactly how this new telepathy technology will impact our lives. But one thing seems certain. Synthetic Telepathy is coming…and it’s coming quickly.

America’s Heat Gun?

The other day, the U.S. military unveiled the newest weapon in its arsenal…Active Denial System. The Active Denial System emits invisible electromagnetic beams of intense heat, intended to disperse unruly crowds. In other words, it’s a massive heat gun.

The Active Denial System: America’s Heat Gun?

The Active Denial System heat gun is a nonlethal weapon. It’s mounted onto vehicles and used for crowd control purposes.

“You’re not going to see it, you’re not going to hear it, you’re not going to smell it. You’re going to feel it.” ~ Marine Colonel Tracy Tafolla

Supposedly, the Active Denial System heat gun doesn’t cause “cancer, or fertility problems, or birth defects.” And it’s being touted as a safe alternative to traditional crowd dispersal tactics like rubber bullets and pepper spray. That might be the case…unless, of course, something goes wrong and the heat gun burns the crowd to a crisp.

The Pentagon hasn’t placed any orders yet for the Active Denial System heat gun but expect to see it on the battlefield sometime soon. After that, it’s only a matter of time before the heat gun gets rolled out to police forces across the nation…

A Bullet…that Steers Itself?

The world is full of strange “future weapons.” But is it ready for self-steering bullets, capable of hitting targets over a mile away?

Future Weapons: A Bullet that Steers Itself?

So, what kind of future weapons is the world ready for? Is it ready for self-steering bullets, capable of hitting targets over a mile away? The military and Lockheed Martin seem to think so. Apparently, this new “future weapon” could be used to “minimize civilian casualties.” Unless, of course, civilians happen to be the targets in the first place. Here’s more on this strange new “future weapon” from BBC News:

A self-guiding bullet that can steer itself towards its target is being developed for use by the US military. The bullet uses tiny fins to correct the course of its flight allowing it to hit laser-illuminated targets.

It is designed to be capable of hitting objects at distances of about 2km (1.24 miles). Work on a prototype suggests that accuracy is best at longer ranges. A think tank says the tech is well-suited to snipers, but worries about it being marketed to the public…

Bulletproof…skin?

Will soldiers of the future eschew bulletproof vests for bulletproof skin?

Will Soldiers of the Future have Bulletproof Skin?

By integrating spider silk into human skin cells, researchers have developed human tissue that can withstand a bullet (okay, a bullet fired at half-speed). Still, it’s a pretty impressive achievement. Here’s more on this new bulletproof skin from New Scientist:

What if your skin could resist a speeding bullet? Now a new futuristic tissue designed by artist Jalila Essaïdi, which reinforces human skin cells with spider silk, can stop a whizzing projectile without being pierced. Although its threads may look fragile, a spider-silk weave is four times stronger than Kevlar, the material used in bulletproof vests.

…But its resistance has its limits: when shot at a full speed of 329 m/s, the bullet pierces the material and travels through it.
