Soldiers or Terminators? U.S. Army mulling rifle that fires 250 rounds per second

Forward Defense Munitions L5 Caseless Ammo Rifle

Let it never be said that the world-renowned United States Army isn’t willing to push the envelope when it comes to tech — or to look for it in unusual places. According to a new report, the U.S. Army is testing a prototype four-barrel rifle that’s capable of firing all four rounds simultaneously. With all four barrels housed in one metal sleeve, the next-gen rifle looks like something out of a sci-fi movie. Where did it find such a beast of a firearm? The sleek, futuristic-looking “ribbon gun” was designed in a garage in Colorado Springs by inventor Martin Grier, owner of Forward Defense Munitions, who spent an estimated $500,000 making his dream a reality.

While a vertically stacked, four barrel gun capable of firing all rounds at the same time sounds all kinds of deadly, an additional hair-raising detail is that the gun can alternatively fire at a theoretical rate of 250 rounds every second. It can house four-round blocks of ammunition, which are fed into the gun horizontally. Each ammo block is able to hold four rounds of 6mm bullets, a caliber that allows for increased range and penetration. The innovative firing system is based on an electric actuator that’s similar to electrically fired weapons such as the M61 Vulcan 20mm Gatling gun and M134 Gatling gun.

Despite all of these heavyweight features, however, the new rifle is anything but heavy. It weighs just 6.5 pounds, which makes it lighter than the U.S. Army’s 7-pound M4 carbine, the gun used by the U.S. Armed Forces as its primary infantry weapon and service rifle.

“Our guys have the same junk weapons as our adversaries,” Martin Grier told the Colorado Springs Gazette, which first ran the story. “I want to give them a Clint Eastwood kind of edge.”

Based on the footage we’ve seen of the weapon, as shown off at the 2018 SHOT Show in Las Vegas, the “Clint Eastwood kind of edge” description is about right. And to paraphrase one of Eastwood’s most iconic movie lines, we can’t imagine too many of the U.S. Army’s enemies are feeling too lucky right now. Punk.

I let Gemini take care of my houseplants, and they’ve never looked better
Study guide created by Gemini

I am, by every reasonable measure, a serial plant killer. I've lost count of the pothos, the peace lilies, the one very expensive fiddle-leaf fig that judged me silently for a month before giving up entirely. My problem was never a lack of love. It was that I'd either drown them out of guilt or forget they existed for a fortnight, with no middle ground. So when I started leaning on Gemini for the odd everyday question, letting it babysit my plants wasn't some grand plan. It happened almost by accident, and now my flat looks like something a person with their life together would own.

It started the way most of my plant emergencies do, with a leaf going a color it definitely shouldn't. Instead of doom-scrolling through contradictory Google searches like I usually would, I snapped a photo, handed it to Gemini, and asked what was wrong. What I got back was a proper answer, and it was the first of many.

I underestimated this NotebookLM feature until it completely changed how I study
google-adds-data-tables-feature-in-notebooklm

I'll admit it: I ignored NotebookLM's Mind Maps feature for far longer than I should have. I mostly used the app to ask questions about my documents or generate Audio Overviews and Short Video Overviews, while that little Mind Map button sat untouched. I assumed it was more of a nice-to-have than something I'd actually use. Turns out, I was completely wrong.

The Concorde dream is within reach. NASA X-59 just has to silence the supersonic boom
The jet built to kill the sonic boom just reached full speed
Lockheed Martin’s X-59

NASA has already proved that its needle-nosed X-59 can move seriously fast in recent test flights. Now, the next step is to find out whether it can break the sound barrier without announcing its arrival to everyone below. The experimental aircraft recently reached Mach 1.4, or about 924 mph (1,487 kph), at an altitude of 55,000 feet. Those are the target conditions NASA plans to use during future tests of the X-59’s quieter sonic signature, making the flight a major milestone for the agency’s Quesst mission.
