The United States tested an advanced hypersonic missile system last week that will “offer next generation capability” to the US military, the Pentagon’s Defense Advanced Research Projects Agency (DARPA) said on Monday. The test flight comes just a few months after Russia tested a similar missile. The US missile system, called a “Hypersonic Air-breathing Weapon Concept” (HAWC), was developed by the aerospace and defense giants Raytheon Technologies and Northrop Grumman. During the test, which was carried out in partnership with DARPA and the US Air Force last week, the missile was released from under the wing of an aircraft, and...

Engine technology being developed for a British space plane could also find its way into hypersonic aircraft built by the U.S. military. The U.S. Air Force Research Laboratory is studying hypersonic vehicles that would use the Synergetic Air-Breathing Rocket Engine (SABRE), which the English company Reaction Engines Ltd. is working on to power the Skylon space plane, AFRL officials said. "AFRL is formulating plans to look at advanced vehicle concepts based on Reaction Engine's heat-exchanger technology and SABRE engine concept," officials with AFRL, which is based in Ohio, told Space.com via email last month. ... SABRE burns hydrogen and oxygen....

'A UK company which hopes to build a re-usable space plane has won an important endorsement from the European Space Agency (ESA) after completing key tests on its novel engine technology. Reaction Engines believes its novel Sabre engine, which would operate like a jet engine in the atmosphere and a rocket in space, could displace rockets for space access and transform air travel by bringing any destination on earth to no more than four hours away. That ambition was given a boost this week by ESA, which has acted as an independent auditor on the Sabre test programme. "ESA are...

A revolutionary UK spaceplane concept has been boosted by the conclusions of an important technical review.The proposed Skylon vehicle would do the job of a big rocket but operate like an airliner, taking off and landing at a conventional runway. The European Space Agency's propulsion experts have assessed the details of the concept and found no showstoppers. They want the next phase of development to include a ground demonstration of its key innovation - its Sabre engine. This power unit is designed to breathe oxygen from the air in the early phases of flight - just like jet engines -...

Launching into orbit could become a little easier and cheaper, thanks to a futuristic space plane that looks like it might have flown straight out of a Star Wars film. The European Space Agency and British government have awarded $1 million euros ($1.28 million dollars) to Reaction Engines Limited (REL), a British aerospace company, as part of a multi-million dollar development program for an air-breathing rocket engine that could power the Skylon spaceplane. The unpiloted, reusable vehicle is designed to take off from an airstrip, deliver cargo into orbit and return to the same runway.

A new jet engine design able to fly seven times the speed of sound is scheduled to launch over Australia on Friday. The scramjet engine, known as Hyshot III, has been designed by British defence firm Qinetiq. If successful, it could pave the way for ultrafast, intercontinental air travel, and substantially cut the cost of putting small payloads into space. The engine will launch on a rocket owned by the University of Queensland. It is the first of three test flights planned for this year by the international Hyshot consortium. The first Hyshot engine was launched in 2001 but the...

Long before hitching a ride to the moon aboard Apollo 11, then US Air Force test pilot Neil Armstrong was zipping around in a rocket-powered North American X-15, which to this day remains the fastest manned, winged aircraft ever built. That flight record of Mach 6.72 or 7,274km/h was set by pilot William “Pete” Knight in 1967. Now, some 59 years later, America still hasn’t fully realised the promise that experimental flight vehicle held for military operations. Despite many breakthroughs in fields of hypersonic propulsion and high-temperature materials, the air force doesn’t imagine an affordable and operationally relevant surveillance and...

Boeing's X-51A WaveRider — a jet-fueled, air-breathing hypersonic rocket — is one step closer to reality. In tests over Edwards Air Force Base in California, a B-52 bomber carried the X-51A WaveRider aloft for the first time, announced manufacturer Boeing Corp. The test was a key milestone in preparation for the X-51A to light its supersonic "ramjet" engine and propel the WaverRider at hypersonic speed for about 5 minutes, before plunging into the Pacific Ocean

Here are the top five aerial weapons that one day could change the face of modern warfare. Relying on the most advanced technology in the world, these hyper-advanced projectiles may outmaneuver, outrun, and outmatch America’s foes around the globe, whenever the need arises. 1) The Mach-5 Cruise Missile If a cruise-missile at supersonic speed is a full-throttle Ford Mustang, then a missile that hits Mach 5 is a Formula 1 racer going all out. The problem is, that hypersonic Mach 5 pace — clocking in at five times the speed of sound– has yet to be reached by munitions. Until...

coondoggie writes "The aspiration that jets may someday fly at over six times the speed of sound took a very real step toward reality recently, as the US Air Force said it successfully married the test aircraft, known as the X-51A WaveRider, to a B-52 in preparation for a Dec. 2 flight test. The X-51A flight tests are intended to demonstrate that the engines can achieve their desired speed without disintegrating. While the X-51 looks like a large rocket now, its applications could change the way aircraft or spaceships are designed, fly into space, support reconnaissance missions and handle long-distance...

The Space Shuttle may be dead, but the Air Force is looking to pick up the slack. Last month they launched their secret space plane, the X-37B, from a base from Florida. The spacecraft is currently on the first part of a top secret nine month mission that will end with a soft landing in California. So is the X-37B the Air Force's first foray into creating the world's first starfighter? Absolutely, not says the Air Force. Gary E. Payton, under secretary of the Air Force for space programs says that the plane carries "no offensive capabilities." He states, "The...

Sustained hypersonic flight above speeds of Mach 5 by vehicles using air-breathing, jet-fuel-powered engines could become achievable within the next dozen years. Successful recent ground tests of jet-fueled, ramjet/scramjet demonstrator engines by Pratt & Whitney Rocketdyne and Aerojet represent important progress toward flight-testing of three separate hypersonic-vehicle programs. In September, Pratt & Whitney Rocketdyne (PWR) completed 10 months' testing of a sub-scale combustor for a hydrocarbon-powered, dual-mode ramjet engine designed to operate over a wide range of Mach-number speeds -- that is, multiples of the speed of sound. Using JP-7 jet fuel, PWR ran the combustor successfully at a variety...

Phantom Ray will pick up where the UCAS program left off in 2006 by further demonstrating Boeing’s unmanned systems development capabilities in a fighter-sized, state-of-the-art aerospace system. The Boeing UCAS program began with the X-45A, which successfully flew 64 times from 2002 to 2005. Those flights included a demonstration exercise with two X-45A aircraft that marked the first unmanned, autonomous multivehicle flight under the control of a single pilot...] ...Currently planned Dec. 2, the Air Force Flight Test Center’s B-52 will carry the X-51A to 50,000 feet over the Pacific Ocean then release it. A solid rocket booster from an...

The U.S. Air Force is gearing up for the first of four planned test flights of a hypersonic aircraft designed to operate for much longer durations and cover far greater distances than previous platforms of its type. The maiden flight of the X-51 Waverider aircraft — the first U.S. hypersonic vehicle to fly in six years — is scheduled to take place later in March. Boeing Defense, Space & Security Systems of St. Louis has been developing the aircraft since 2003 on behalf of the Air Force Research Laboratory and Defense Advanced Research Projects Agency. The missile-shaped X-51 will be...

PALMDALE - The next step in hypersonic flight test is under development in a hangar at The Boeing Co.'s facility at Air Force Plant 42. The unmanned X-51A "WaveRider" is a scramjet engine flight demonstrator, expected to provide flight test data at speeds beyond Mach 6 - about one mile per second - using its unique engine design. In a scramjet - or supersonic combustion ramjet - engine, air is scooped into the engine duct, then forced through a combustion chamber, where fuel is mixed in and ignited. This produces energy, which is forced out the rear of the engine...

I've had sources ask to meet me in some pretty odd places. But there was one meeting last year that had to be just about the strangest request yet. It wasn't just that this very-recently retired Defense Department strategist wanted to meet at the Pentagon City Mall -- that's a pretty common place to grab an off-the-record cup o' joe. It was where in the mall he had in mind: at the Nordstrom's coffee shop, tucked all the way in the far reaches of the store, just past the little kid's clothes section. So I walk past the rows of...

EDWARDS AFB - The base that first broke the sound barrier is once again pushing the boundaries of flight test, this time with sustained flight at hypersonic speeds. The Air Force Flight Test Center at Edwards Air Force Base is responsible for the upcoming flight test of the X-51, a vehicle designed to travel at speeds greater than five times the speed of sound. The project takes on special meaning as no hypersonic project has made it to the flight test phase in a number of years, he said. The last one - also from Edwards - was NASA's X-43A,...

The dreams of being able to fly from New York to London in under an hour are once again put on hold, as the latest effort to fly at over five times the speed of sound has ended in failure. A US Air Force test of a missile that is supposed to travel at six times the speed of sound has ended in failure when the vehicle went out of control and crashed in the Pacific Ocean. It is still unclear what went wrong with the test flight. However, it joins a long list of failed hypersonic flights that shows...

<p>An experimental scramjet-powered, ultrahigh speed strike vehicle is emerging as the Pentagon’s main choice for a new long-range, rapid attack weapon, a senior Pentagon official says.</p>
<p>Alan R. Shaffer, principal deputy assistant defense secretary for research and engineering, told a defense industry conference that prototypes and recent tests proved concepts for hypersonic arms, and several systems are part of a high-priority effort by Pentagon weapons developers, despite the era of sharply-diminished defense spending.</p>
