Functional laser weapons are just five years away. Advocates hope that won’t always be the case. The Air Force has been working on airborne laser weapons for more than 40 years, but a fielded system remains elusive. Experts also warn that the US does not enjoy a commanding lead in laser research. And the Air Force’s flagship laser weapon program, the Airborne Laser (later called the Airborne Laser Testbed) was terminated late last year and is now being dismantled. Still, service and industry experts predict there is plenty of reason for realistic optimism. Operational laser systems that can perform a...

The first night refueling in the history of the Lockheed Martin F-35 program was completed Thursday at Edwards Air Force Base, Calif. Piloted by U.S. Air Force Lt. Col. Peter Vitt, AF-4, an F-35A conventional takeoff and landing variant, rendezvoused with an Air Force KC-135 tanker and successfully received fuel through the F-35’s boom receptacle. Vitt’s sortie lasted more than three hours. In addition to qualifying with the KC-135, the F-35 Integrated Test Force at Edwards AFB will also conduct night refueling tests with the KC-10.

There have been a number of articles lately about the U.S. developing a new unmanned aerial vehicle in secret. Dave Majumdar, at Air Force Times, recently had an article about how the U.S. Air Force’s decision to postpone development of a next generation unmanned combat aircraft suggests that service might be developing something else in the “black world.” The article quoted USAF intelligence chief Lt.-Gen. Larry James who said that there is no immediate need for a next generation replacement for the General Atomics MQ-9 Reaper. And the Predator-C Avenger UAV the USAF is buying will be used only as...

European researchers said Thursday they have created a device invisible to a static magnetic field that could have practical military and medical applications. Fedor Gomory and colleagues in Slovakia and Spain designed a cloak for a direct current, or dc, magnetic field that is static and produced by a permanent magnet or coil carrying a direct current. DC magnetic fields are used in MRI imaging devices, in hospitals and in security systems, such as those in airports. The researchers' device, described in a study in Friday's edition of the journal Science, features a cylinder with two concentric layers. While the...

The F-35 Lightning II joint strike fighter program -- the centerpiece of future tactical aviation and a key to implementing new military strategic guidance -- made strong progress in its development last year, a defense official said today. Frank Kendall, acting undersecretary of defense for acquisition, technology and logistics, told the House Armed Services Committee that the fighter aircraft is essential to the Defense Department, and that it made "strong progress" in 2011. "Last fall, the department engaged in a strategy and budget review, where everything -- and I do mean everything -- was on the table," Kendall said. "After...

Brain research and associated advances such as brain-machine interfaces that are funded by the U.S. military and intelligence communities raise profound ethical concerns, caution researchers who cite the potentially lethal applications of such work and other consequences. Rapid advances in neuroscience made over the last decade have many dual-use applications of both military and civilian interest. Researchers who receive military funding — with the U.S. Department of Defense spending more than $350 million on neuroscience in 2011 — may not fully realize how dangerous their work might be, say scientists in an essay published online today (March 20) in the...

Ubiquitous in science fiction, rail guns are a hot area of military research in real life too. But will we ever really get to use them the way people in science fiction do? And could rail guns be used for a non-violent reason — inexpensively launching payload into space? Halo Reach ends with your Spartan taking up a mounted rail gun to destroy an incoming Covenant ship. Rail guns are the basis for a funny aside in Mass Effect 2. They're used in Babylon 5 and Stargate Atlantis and The Last Starfighter. And they're a devastating hand-held weapon in the...

Sandia National Laboratories is seeking a partnership with a private company to commercialize a new guided bullet that its engineers have invented, according to the U.S. government lab, which is managed by Lockheed Martin. The Sandia researchers, Red Jones and Brian Kast and their colleagues, created a dart-like self-guided bullet for small-caliber firearms that uses laser guidance to hit targets more than a mile away. "We have a very promising technology to guide small projectiles that could be fully developed inexpensively and rapidly," Jones said. The prototype was built using commercially available components and the initial testing in computer simulations...

Russia is reportedly close to finalizing a major sale of advanced fighter aircraft to China worth $4 billion. Such a sale, newsworthy in itself, would have been hard to imagine as recently as a few years ago considering the history of previous agreements. The anticipated deal, first reported by Kommersant, sees the two sides “practically agreed on the delivery of 48 Su-35 multirole fighters, worth $4 billion, to China.” Some reports suggest that Chinese officials have dismissed talk of such a deal. But if true, an agreement like this would certainly make sense for Beijing, giving China access to an...

DARPA is unveiling a portable laser weapons system, HELLADS, which seems like something out of a sci-fi movie. The new laser application, created by General Atomics Aeronautical Systems with a custom power system from Saft Batteries, will help change the way the American military fights future wars. Current military laser systems are bulky contraptions which are mainly the size of a passenger jet, while the proposed DARPA weapon can fit on the back of a flatbed truck. The 150-kilowatt, solid state laser weapon is strong enough to take down drones or other aerial targets; a prototype is expected to be...

The program executive officer for the problem-plagued F-35 said Thursday he has "great confidence" the multi-service fighter can deliver the oft-promised stealth and the sophisticated package of sensors. Vice Adm. David Venlet said he has "measured data" to show that. In a late afternoon address to an audience of defense and financial industry representatives, Venlet said all the current problems with the Lockheed Martin-built aircraft that have been highlighted in the media and congressional hearings "are in the normal range of fighter aircraft development." The problems Venlet cited included the sophisticated helmet that should allow the pilot to see on...

During a recent trip to Yuma Proving Ground, in Arizona, I passed a unique looking artillery piece in a remote area of the installation. It has an extremely long barrel and appeared to be anchored in a concrete abutment. Having more than a passing interest in ordnance I made some inquiries as to origins and purpose of the gun. What I had stumbled across, on that hot desert day, was one of three unique guns that had been part of a very ambitious undertaking called the “High Altitude Research Project,” or HARP. The brainchild of Jerry Bull (of “Iranian Super...

Over the past decade, the Air Force has poured more than $80 billion into space technologies, including new satellites, launch services and information systems. The plan for the coming years is to spend considerably less as pressure grows to reduce the U.S. defense budget. The Air Force still intends to modernize key satellite constellations and provide space-based communications and surveillance services for the military and intelligence community. But program costs are going to be scrutinized at an unprecedented level of detail, Air Force officials said. Every major space program is now the subject of “should-cost” reviews, which is the Pentagon’s...

The U.S. Air Force's second X-37B space plane marked one year in orbit Monday, continuing its clandestine mission more than 200 miles above Earth. The robotic spacecraft's purpose is secret, but Air Force officials acknowledge the vehicle is performing well one year after it blasted off on a United Launch Alliance Atlas 5 rocket on March 5, 2011. "We are very pleased with the results of the on-going X-37B experiments," said Lt. Col. Tom McIntyre, X-37B program director in the Air Force's Rapid Capabilities Office. "The X-37B program is setting the standard for a reusable space plane and, on this...

The Pentagon has mothballed a laser-equipped jumbo jet after 15 years and $5 billion worth of research to develop an airborne missile defense system. Budget cuts shot down the Airborne Laser Test Bed but some research into anti-missile lasers will continue, according to the U.S. Missile Defense Agency. "We didn't have the funding to continue flying the aircraft," agency spokeswoman Debra Christman told the Los Angeles Times (http://lat.ms/xEnw3z ). The plane, a Boeing 747 mounted with a high-energy chemical laser, has been sent into storage at Davis Monthan Air Force Base, the agency said. The base near Tucson, Ariz., serves...

China usually holds its military hand very close to the vest--that, or things “mysteriously” leak that it doesn’t (does) want the world to know about--so we’re left to wonder why the People’s Republic has decided to publish this in the journal Advanced Materials Research. Nonetheless, it’s pretty interesting. Chinese navy researchers have plans for a new submarine hunting scheme that uses ship-launched UAVs running genetic algorithms. Genetic algorithms narrow down a range of possibilities to an optimal solution much the way evolution does (at least in a simplified sense)--by weeding out the weaker offspring and mating the best with the...

Researchers believe that new "thinking caps", could help provide super-human strength, highly enhanced concentration or thought-controlled weaponry. A British ethics group is investigating the ethical dilemmas posed by inventions that interfere with the brain's inner workings. The Nuffield Council on Bioethics (NCB) has launched a consultation on the risks posed by such new technologies, the global market for which it says is worth $8bn (£5bn) and "growing fast. With the prospect of future conflicts between armies controlling weapons with their minds, the Council, an independent body, is wanting to identify what issues that come with blurring the lines between humans...

Boeing has announced that it has completed delivery of 257 F/A-18E/F Super Hornet strike fighters and EA-18G Growler electronic attack aircraft to the U.S. Navy. Each aircraft was delivered ahead of schedule and within the contract budget. The aircraft were delivered to the Navy from 2007 through 2011 under a multi-year procurement (MYP) contract awarded to Boeing on Dec. 29, 2003. The Navy purchased the aircraft during fiscal years 2005-2009. Multi-year procurement contracts provide a stable production environment that enables manufacturers and suppliers to reduce cost through bulk purchasing and productivity enhancements. "Super Hornets and Growlers provide unmatched, proven and...

Lockheed Martin has unveiled a new version of the F-16 at the Singapore Airshow. The F-16V will feature enhancements including an active electronically scanned array (AESA) radar, an upgraded mission computer and architecture, and improvements to the cockpit - all capabilities identified by the U.S. Air Force and several international customers for future improvements. With nearly 4,500 F-16s delivered, this is a natural step in the evolution of the world's most successful 4th generation fighter. The Fighting Falcon program has continually evolved as it began with the F-16 A/B as the lightweight fighter then transitioned to F-16 C/D and Block...

America's new long-range bomber program is "underway," will involve somewhere between 80 and 100 planes and will be delivered sometime in the mid-2020's. "And that's about all we're saying," Air Force Secretary Mike Donley told reporters. It's been known for some time that the bombers will not fly alone but will be part of a family of systems that may include UAVs and other systems. The really interesting part of all this is the secrecy and why it's so dark. It would seem to indicate several things: that the U.S. does not want potential competitors such as China or Russia...
