The evil geniuses at Northrop Grumman successfully completed the first flight of its X-47B unmanned stealth bomber a few days ago at Edwards Air Force Base in Edwards, California. In the air for a full twenty-nine minutes, the tailless, fighter-sized UAV flew to 5,000 feet and completed several racetrack-type patterns, before landing safely at 2:38 pm PST. The aircraft will continue to undergo tests at Edwards AFB before heading to Naval Air Station Patuxent River, Maryland, later this year. The ultimate goal is to get this bad boy taking off and landing on US Navy carriers. Carrier trials are currently slated for sometime in 2013. Video, PR after the break.

When discussing drones, we usually think of the Af-Pak theater (or perhaps joy ridin' UK teens), so it was with some amusement that we heard about a little border excursion that a Mexican UAV made into American airspace a few days ago. According to reports, the device -- believed to be an Israeli-made Orbiter Mini -- was being operated by the Mexican government (on its side of the border) when it experienced some sort of "mechanical malfunction" and crossed over to El Paso, Texas, where it was discovered on a resident's front lawn last Tuesday. The Orbiter Mini, manufactured by Aeronautics Defense Systems, has a six foot wingspan and will stay in the air up to four hours.

While the controversial (and deadly) use of combat drones certainly shows no signs of abatement, the Air Force has announced that a recent purchase of 268 Predators will be its last. The vehicles, manufactured by General Atomics, should be in the hands of the military by early next year. For its part, the USAF will apparently switch to purchasing Reaper drones -- which can carry a wide variety of armaments, including Sidewinder or Hellfire missiles and laser-guided bombs. We just hope that they aren't using the unencrypted video feeds that made Predators so easy to monitor.

A Northrop Grumman MQ-8 Fire Scout UAV strayed into restricted airspace above Washington DC after departing Patuxent River Naval Air Station in Maryland on August 2, the result of a software logic flaw that caused the operator to momentarily lose contact with the drone. Programmed to circle when communications are severed, the chopper failed to follow its failure protocol, instead heading twenty-three miles on a north/northwest trajectory -- which could have had serious consequences had it been equipped with 70mm Hydra rocket pods or Hellfire tankbuster missiles. Although this type of incident is rare, it is not unheard of: last September the Air Force had to take down an MQ-9 Reaper in Afghanistan when it failed to adhere to failure protocols after dropping communications with the ground. At least, that's what we'd like to believe... the alternative scenario is too frightening to consider.

With all the excitement surrounding the solar powered UAV's record-breaking flights, we would be remiss if we didn't mention that QinetiQ's Zephyr has finally landed in an airfield in Arizona, 14 days and 24 minutes after take-off. This quadruples the previous unofficial world record for unmanned flight (which it set itself in 2008). This is a dramatic proof-of-concept, having flown longer without refueling than any other airplane. We'd like to imagine that this technology would be used primarily for delivering toys to children in developing nations, but something tells us that will have to wait until the military gets its hands on it.

We've seen UAVs that hover in the past, but if you're looking for something that eschews rotors for nearly silent ducted fans, you'll need to get your hands on the cyberQuad by Cyber Technology. The fans don't produce sparks (which is why this thing was recently tested with much success in an extended survey of an offshore drilling platform / oil rig damaged by fire), and its "perch and stare" capabilities mean that it can find a stable spot and sit unattended -- not only saving battery time that would otherwise be lost by hovering in place, but taking it all in with whatever video equipment / sensors the operator might have placed on-board. Just the thing for sniffing out enemy combatants and relaying the info to your One Force Tracker-equipped iPhone, perhaps? Get a closer look after the break. [Warning: PDF source link]

Update: Thanks to Randers for hooking us up with some video of the thing in action. It still makes us a little uncomfortable, all that staring...

It sure is nice to see that the military is paying attention to the environment, always on the lookout for greener ways to spy on people, foreign and domestic. Ion Tiger, for instance, is an unmanned vehicle being cooked up at the Naval Research Laboratory that incorporates a hydrogen fuel cell, offering many improvements on earlier battery powered designs -- including a greater range (up to seven times further than that of current designs), heavier payloads, smaller size, reduced noise, a low heat signature, and zero emissions. The Office of Naval Research is making much of the possible civilian potentials for this technology, pointing out that research contributes "directly to solving some of the same technology challenges faced at the national level," but we know the truth: the US military is in cahoots with Greenpeace. You heard it here first, folks. Video after the break.

You know how it is -- we're frightened and appalled by the thought of unmanned killing machines, but if they must exist we really, really want to play with one. The US Army's latest nightmarish deathcopter / awesome tech toy is a little something called the Autonomous Rotorcraft Sniper System (ARSS). Essentially a .338-caliber rifle mounted to the bottom of a Vigilante unmanned helicopter (though it could eventually be made to work on a Predator drone, for instance), this bad boy utilizes a modified Xbox 360 game controller for targeting while the vehicle itself stays put courtesy of its autopilot functions. Never again will your favorite sniper need to leave the comfort of his barracks! Airborne testing begins in July, with autonomy to come soon after that and a possible robot apocalypse estimated for Q4 2011.
