Raytheon tests motor for DARPA’s MAD-FIRES self-defense interceptor

Posted by in categories: military, robotics/AI

May 7 (UPI) — Raytheon Company successfully tested a hot fire rocket motor for DARPA’s Multi-Azimuth Defense Fast Intercept Round Engagement System.

The test for the U.S. Defense Advanced Research Projects Agency was conducted on an undisclosed date at Yuma Proving Ground in Arizona, Raytheon announced Monday.

The MAD-FIRES interceptor is designed to provide self-defense capability that defeats multiple waves of anti-ship missiles, unmanned aerial vehicles, small planes, fast in-shore attack craft and other platforms that “pose a perennial, evolving and potentially lethal threat to ships and other maritime vessels,” according to the agency.

Army Demonstrates a Weapon That Shoots Laser-Guided Lightning Bolts

Posted by in categories: climatology, military, particle physics

Over at Picatinny Arsenal, the research and development facility and proving ground for the U.S. Army’s weaponry, engineers are developing a device that shoots lighting bolts along a laser beam to annihilate its target. That’s right: lighting bolts shot down laser beams. This story could easily end right here and still be the coolest thing we’ve written today, but for the scientifically curious we’ll continue.

The Laser-Induced Plasma Channel (LIPC) can be used to destroy anything that conducts electricity better than the air or ground surrounding it (unexploded ordnance seems a good candidate here). It works off of some pretty basic principles of physics, using a laser to carve an electromagnetic path through the air that accommodates a high-voltage beam. Create that path, crank up the voltage, and your target is toast.

It works like this: a high intensity, super-short duration (maybe two-trillionths of a second) laser pulse will actually use air like lens—surrounding air focuses the beam, keeping the laser pulse nice and tight rather than scattering it. If the pulse is strong enough, it actually creates an electromagnetic field around itself that’s so powerful it strips electrons from air molecules, essentially creating a channel of plasma through the air. Since air is composed of neutral particles (that act as insulators) and the plasma channel is a good conductor (relative to the un-ionized air around it) the path of the laser beam becomes a kind of filament.

New Russian Submarine Can Launch Nuke-Carrying Drones

Posted by in categories: drones, military

M.A.D.

The Poseidon drone can travel a full kilometer beneath water level, making it difficult to detect and stop once its deployed. And that level of stealth — especially when it’s tipped with a deadly nuclear bomb — has other nations concerned.

“It is worrying that countries are developing new nuclear capabilities,” Ine Eriksen Søreide, Foreign Minister of Norway, told The Barents Observer.

Catastrophic meteors: How space scientists hope to protect ‘the only planet we know’

Posted by in categories: military, space travel

NASA is warning that meteors pose a major threat to Earth, so agencies are already testing out ways to defend against them by using lasers or by ramming spacecraft into them.

During a conference last week, NASA administrator Jim Bridenstine explained that not taking meteors seriously could have catastrophic consequences. In 2013, a 20-metre meteor exploded over Russia and the sonic boom caused windows and glass to shatter, injuring more than 1,000 people.

That relatively small meteor contained more than 30 times the energy of the atomic bomb the United States dropped on Hiroshima during the Second World War.

Navy’s Giant New Robot Sub Will Prowl Ocean For Months Autonomously

Posted by in categories: military, robotics/AI

The Navy just awarded Boeing a contract to build a giant robot submarine, called the Orca Extra-Large Unmanned Undersea Vehicle, which it says will prowl the depths of the ocean autonomously for months at a time.

The U.S. Naval Institute says the sub will be used for “mine countermeasures, anti-submarine warfare, anti-surface warfare, electronic warfare and strike missions.”

The biggest comparison of sci-fi spaceships ever is complete at last

Posted by in categories: military, space travel

At last, it’s done. The biggest spaceship size chart ever created is now complete and fully operational. 4,268 x 5,690 pixels of technological terror that includes everything from the smaller Star War ships to EVE. According to its author, Dirk Loechel, this is the last update. It’s epic.

The last update

For real this time: This is the final major content update, though if there are issues I’ll still fix them. I also haven’t forgotten I wanted to vectorize the writing. It’s still on the radar. But content-wise, I think that is about all I can put in.

Sigma Labs PrintRite3D technology validated by DARPA study

Posted by in category: military

New Mexico additive manufacturing software developer Sigma Labs, has obtained third-party validation of its PrintRite3D platform in a study by U.S. defense agency DARPA.

The study discusses the validation process involved in producing complex metal parts of consistent quality. It was sponsored by DARPA’s Open Manufacturing Program and conducted in conjunction with aircraft engine manufacturer Honeywell Aerospace, which has been collaborating with Sigma labs since 2014.

As an agency of the United States Department of Defense (DoD), DARPA is responsible for the development of emerging technologies for use by the military. In line with this goal, it created the Open Manufacturing program to ‘lower the cost and speed the delivery of high-quality manufactured goods with predictable performance.’
