We're beginning to think the US government is playing tricks with our head. Let's see, in late 2004, a Boeing anti-missile airborne laser achieved first light; in October of 2006, a laser-equipped 747-400F was deemed ready for testing; in January of 2007, an MD-10 with Northrop Grumman's Guardian anti-missile system took off; now, we're back to the testing stage? Something doesn't add up. Whatever the case, we're being fed information that leads us to think that the US Air Force's Airborne Laser has moved on to some "other" stage of testing. More specifically, engineers are making sure its "sequencing and control" functions are operating normally. Unsurprisingly, we're left in the dark as to when this thing will see action (again?), but consider our interest piqued for a reason The Man didn't intend.

Air Force buffs, prepare to salute a true American hero as it makes it way into the annals of military history: the F-117 stealth fighter. The planes -- one of the most enigmatic members of the military's arsenal -- will be making their final trip on April 21st from Holloman Air Force Base in New Mexico to Tonopah Test Range Airfield in Nevada, the home of their first flight. The aircraft is being replaced by a newer model, the F-22 Raptor, and the government says it has no plans to bring the radar-dodging planes out of retirement. In all, there have only been 59 F-117s that have rolled off the assembly line, 37 of which have already been taken out of the skies, and another seven which have crashed. We'll miss you, F-117, and all the totally awesome, completely secret stuff you did.

See, the problem with bioengineering isn't moral or ethical dilemmas, or even homicidal robo-droids enslaving humanity. It's that if you let researchers go wild, eventually they'll find a way to make LEDs out of salmon sperm, threatening the sanctity (and sperm-free-ness) of your entire gadget-based lifestyle. Yet that's exactly what Professor Andrew Steckl of the University of Cincinnati has managed to do, using the DNA found in salmon sperm to enhance the brightness of LEDs. The so-called BioLEDs are being developed in cooperation with the Air Force (yes, the Air Force -- they had a "good source" of salmon sperm, apparently) and they've been so successful that Steckl has been getting salmon sperm from researchers worldwide "wanting to see if their sperm is good enough." Steckl says that since salmon sperm is considered a waste product of the fishing industry, BioLEDs are particularly green -- kind of like our faces right now.

We've already seen the PlayStation 3 put to use for some non-gaming tasks (other than playing Blu-ray movies), and it now looks like the U.S. Air Force is aiming to get in on the act as well, with it recently putting out a so-called Request for Proposal that is seeking 300 PS3s for a "technology assessment." Needless to say, their primary interest is in the console's powerful Cell processor, which they say is the "only brand on the market that utilizes the specific cell processor characteristics needed for this program at an acceptable cost." Exactly what that program entails is unsurprisingly being kept under wraps, with the RFP only going so far to state that the Air Force Research Laboratory is "conducting a technology assessment of certain cell processors." Whatever it is, the Air Force certainly seems to be trying to keep costs as low as possible, with them apparently only interested in the 40GB model.

Sure, we've seen monolithic solar farms before, but the 14-megawatt Nellis solar energy system is a beast that stands alone -- for now, at least. As of today, this farm is hailed as America's "largest solar photovoltaic system," but if all goes to plan, Cleantech America will grab those honors when it completes a massive 80-megawatt project in neighboring California. Nevertheless, this system -- which is housed at the Nellis Air Force Base in Nevada -- will reportedly generate "30 million kilowatt-hours of clean electricity annually and supply approximately 25-percent of the total power used at the base, where 12,000 people live and work." Of course, some 140 acres of land have been covered with 72,000 solar panels in order to make it happen, but it's not like anything else is going out there (CES and rabid gambling notwithstanding).

We've seen some interesting solutions to keeping UAVs powered for extended missions, but none so diabolical as actually landing on the enemy's power lines and using their juice to power up. That's the plan behind the Power Line Urban Sentry (PLUS) project currently being run by the Air Force Research Laboratory and private firm Defense Research Associates, and it's already yielded UAVs that can land on power lines and charge in three hours. The project started with attempts to charge by simply flying near power lines, but when that method yielded only micro-watts of juice, focus shifted to actually landing on the lines. The team is planning all sorts of other capabilities for the tech, including navigation systems -- "Power lines are like highways in the sky," says one of the researchers -- and auxiliary surveillance systems that power up when jacked in. On top of all that awesomeness, the team is also working with an outfit called the Center for Morphing Control to disguise the UAVs when they sit on the lines -- so far, they say, they've made a small UAV "look like a Coke can." Test flights are scheduled for 2008, and there's still work to be done on the power line latching mechanism, but whatever -- we want one.

Raytheon sure loves its lasers, and it's proving so with the crowd-repelling Silent Guardian. The device, which is part of the Directed Energy Solutions program, is reportedly designed to be mounted onto a military vehicle where it can "throw a wave of agony nearly half a mile," penetrating enemy skin just 1/64th of an inch and not causing "visible, permanent injury." Essentially, the invisible beam has the ability to inflict "limitless, unbearable pain," which seems to stop just as soon as you're able to get out of the ray's path. According to its maker, the machine could be used in "various commercial and military applications including law enforcement, checkpoint security, facility protection, force protection and peacekeeping missions," and it's ready to calm the masses as we speak.

A long line of tenacious competitors is forming to bid on the US Air Force's multibillion-dollar upgrade plan for the current Global Positioning System, with major players Lockheed Martin and Boeing squaring off for the next generation of GPS satellites. The lucky winning bidder will be responsible for construction of eight new GPS III satellites, which will be deployed for use in 2013. Additionally, the Air Force has opened the door for bidders on its ground-based GPS system (GPS OCX, which will utilize existing satellites) and is expected to choose two of three interested parties for the $160 million development contracts. Apparently, the industry is sweet on the Air Force for splitting the space and ground contracts, and instating a relatively new practice which allows companies to bid directly with the government (as opposed to subcontractors). Way to "aim high," everyone.

Shortly after the Navy announced its intentions to utilize unmanned combat aircrafts, the US Air Force is making sure it doesn't get left behind by taking delivery of "its initial BATMAV micro unmanned aircraft systems (UAS)." Among the diminutive crafts is a legion of Wasp IIIs, which have a wingspan of 29-inches, weigh in at just one-pound apiece, and carry integrated forward and side looking electro-optical color / infrared cameras. The backpackable devices are meant to be hand-launched and aim to provide "real-time video imagery to a handheld controller used by tactical units" in reconnaissance, surveillance, and target acquisition missions. Now, if only these things had an ultra-lightweight chaingun strapped under each wing and were available at the local BX, we'd be sold.

We're all quite familiar with the Air Force's so-called 'pain gun' by now -- the millimeter wave weapon that gives targets an unbearable, full-body burning sensation and that may or may not have been recommended for testing on Americans by branch secretary Wynn -- but can you ever really 'know' a crowd control device without seeing it in action? Thankfully the military doesn't think so, which is why the Joint Non-Lethal Weapons Program held what must have been a fun-filled media day this past January, highlighted by the screams and flight response of AP reporter and curiously-willing guinea pig Elliot Minor. In the video after the break, you'll see Minor react to a brief encounter with the pain gun, and although he doesn't cry and wet himself like some might expect our colleagues in the MSM to do, he does admit that the weapon is "quite effective." Apparently there are some more vids of the Air Force's new toy bringing the pain on the linked site, but the military must be spending a lot more money on hurting people than web hosting, because the first clip hadn't even loaded by the time we finished this post.

Now that humans have shot themselves up into space, frolicked on the moon, and have their own space station just chillin' in the middle of the galaxy, what's really left to accomplish out there? How about cruising around at light speed? Apparently, a boastful group of scientists at the Bae Institute in Southern California feel that they're one step closer to achieving the impossible, as the "world's first photonic laser thruster" was purportedly demonstrated. Using a photonic laser and a sophisticated photon beam amplification system, Dr. Bae reportedly "demonstrated that photonic energy could generate amplified thrust between two spacecraft by bouncing photons many thousands of times between them." The Photonic Laser Thruster (PLT) was constructed with off-the-shelf parts and a bit of fairy dust, and it's said that this invention could eliminate the need for "other propellants" on a wide range of NASA spacecrafts, theoretically savings millions on energy costs and enabling longer missions. So while this may be an incredibly novel idea, the chances of this actually working outside of a laboratory seem relatively small, and make sure we're not the guinea pigs strapped into the first craft that utilizes this mystical method of launching, cool?

Apparently, the US military forces have hired some seriously good R&D help, as we've seen the Navy's 8-Megajoule railgun, the Army's war-tested iRobots, and now the Air Force has something of their own to boast about. Nova Sensors of Solvang, California has designed the Variable Acuity Superpixel Technology (VAST) system, which is reportedly capable of tracking "anything slower than a bullet," but the shifty part is that this camera can home in on speeding shells as well, hopefully lending a hand in protecting soldiers in the years to come. The machine focuses on heat bursts emitted in the infrared range by moving bullets in order to detect an incoming projectile; ideally, it would be connected to "active armor" that could move, expand, or otherwise protect an individual or a entire platoon if a stray (or purposeful) bullet was headed their way. The system includes software that "mimics the fovea in human and animal eyes," and essentially provides high-resolution focal points of the incoming shells while making everything else low-resolution in order to showcase what's really important life-threatening. While we're fairly certain these guys won't be coming out with a commercial rendition suitable to block those laser-guided office missiles that nail you in the kneecap every morning, be sure to click on through for a short demonstration of VAST in action.

Republican / Democrat, Christian / Muslim, Team Kristin / Team LC -- despite our many differences, if there's one issue that all Americans can agree on, it's that law-abiding, tax-paying citizens should have unalienable sovereignty over their automatic garage doors. So you can imagine the uproar occurring right now in Colorado Springs, Colorado, ever since the nearby Cheyenne Mountain Air Station (headquarters of the North American Aerospace Defense Command) began testing an emergency radio frequency that has the unintended consequence of pwning numerous garage doors within a 10-mile radius. It would be one thing if the doors just randomly opened and closed on occasion -- smashing a few windshields and delivering a few good laughs -- but apparently the Air Force signal completely flummoxes the garages' RF receivers, often resulting in a pricey house call or an even pricier replacement unit. According to David McGuire, owner of the suddenly-profitable Overhead Door Co, it may be possible to slightly tweak the transmission frequency and put an end to this madness -- an option that Captain Tracy Giles and team are reportedly looking into. While it may be somewhat of an overstatement to call this the most pressing issue that the country has ever faced, if we don't come together as a nation and nip this outrage in the bud, what's stopping Big Brother from waltzing in and breaking our home surveillance cams, car door locks, or -- gasp -- even our remote-controlled projection screens.

Despite the fact that the Air Force's Active Denial System has yet to be deployed against unruly domestic mobs as Secretary Michael Wynn would have liked -- seems like they missed their opportunity prior to the PS3 launch -- Wired is reporting that the branch's so-called "pain gun" has been certified as "safe" by scientists and "excruciating" by the soldiers and monkeys it was tested on. For those of you who don't follow the latest developments in non-lethal weaponry, the ADS -- which has been in development for over ten years -- shoots a 94GHz millimeter wave that triggers an immediate flight response from anyone in its path within 500 meters; although the majority of military test results are classified, it's said that even the toughest subjects can only endure five seconds of the intense burning before running like hell in the opposite direction. Just because the weapon has been green lit for combat, however, doesn't mean that we'll see ADS-equipped Hummers rolling around the streets of Baghdad anytime soon: as Secretary Wynn suggested, international backlash could be significant once photos of beet red, blistered victims start hitting the internet and 24-hour news networks. Still, with the military stuffing this technology into weapons of all shapes and sizes (plane-mounted versions will soon bring the pain from above), it probably won't be too long before these devices become so mainstream that you'll be able to pick one up at Wal-Mart bundled with a free tube of burn cream.
