Waltham missile maker Raytheon Co. has just taken on a tall order from the Department of Defense: Create a cruise missile that could travel more than five times the speed of sound.Raytheon is getting $20 million from the Defense Advanced Research Projects Agency, or DARPA, the Pentagon branch best known for having sponsored the invention of the Internet. This time, the agency wants a technology that weapons designers have dreamed of since the 1930s — a hypersonic missile that travels so fast there’s virtually no defense against it.
What they could be talking about here is the HSSW.http://www.lockheedmartin.com/us/products/high-speed-strike-weapon-hssw.htmlI still wonder if REL's technology could play a part in something even more ambitious than the HSSW.
The Deutsches Zentrum für Luft- und Raumfahrt (DLR), Germany's aerospace research center, has renewed decade-old plans for a suborbital passenger space plane that could fly from Europe to Australia in under 90 minutes. The rocket-powered SpaceLiner, originally conceptualized as a 50-passenger hypersonic airliner, has now been given new urgency and direction with a roadmap for flights within the next 20 years, SpaceLiner project lead Martin Sippel told Aviation Week at last month's American Institute of Aerodynamics and Astronautics' Space Planes and Hypersonics Conference in Glasgow. Sippel spoke at the conference, presenting on SpaceLiner's technical progress and the program's mission definition—which now includes potentially delivering satellites and other payloads to space.
Unfortunately wars and weapons seem to drive technology development. The plus side is technology from a hyper sonic cruise missile should enable development of civil hyper sonic aircraft.

Here is an article about communicating with hypersonic vehicles in flight:http://www.spacedaily.com/reports/Communicating_with_hypersonic_vehicles_in_flight_999.html(about a method: how to overcome the craft surrounding, EM waves reflecting plasma layer)
A hypersonic flight from New York to Los Angeles would take about 30 minutes but if that includes high acceleration at NY and high deceleration at LA then what kind of g's are we talking about? Could civilian passengers withstand that? And what would be the actual cruise time at altitude?
China may have recently conducted a successful test of the fastest hypersonic aircraft in the world, reports Hong Kong newspaper Ta Kung Pao.According to a report released Friday on the official website of state-owned aerospace and defense giant Aviation Industry Corporation of China (AVIC), one of its test flight centers has completed an initial test flight on an unspecified high-altitude, super-fast aircraft with a "unique flying style."
DARPA revives turbine-ramjet concept for hypersonicsA turbine-based combined cycle (TBCC) propulsion system to enable routine hypersonic flight by a vehicle that can take-off and land from a runway is back on the agenda at the Defense Advanced Research Projects Agency (DARPA) after a five-year hiatus.https://www.flightglobal.com/news/articles/darpa-revives-turbine-ramjet-concept-for-hypersonics-426735/
"We're poised on the brink of a new era in air transportation," McBride said. "We do need to go faster. There is a market for supersonic flight over land in an efficient manner that can fly without being an annoyance to everyone on the ground."NASA also is exploring ways to improve the efficiency and reduce the environmental impacts of subsonic aircraft. Engineers are experimenting with blended wings and other innovations.Smith admitted that the difficulty that Congress and the president have experienced in passing budgets has caused problems in sustaining research."None of that is conducive to good work getting done in an efficient way," Smith said. "And we can do better. We need to get to the point where continuity actually lasts beyond just one administration, much less beyond tomorrow. And we're with you on that."Bedke said there is no time to waste in moving these programs forward."It is inevitable that hypersonic technologies are going to happen," he said. "It is not inevitable that we are going to be the country to do it first. But we can be the country to do it first, but we're going to have to put our minds to it, and we're going to have to stop the history of fits and starts, of throwing money at a big program, achieving a wild success, and then having no follow-up. Or throwing a lot of money at too big a program, taking too giant a bite, failing miserably and then deciding hypersonics isn't going anywhere. Neither of those must be allowed to happen in the coming years."

Aerojet Rocketdyne Explores Detonation Engine OptionsFor over 70 years, jet engines have powered airplanes ever more safely and efficiently. But, despite higher core temperatures and pressures, and the introduction of efficient propulsion concepts like the geared fan, conventional gas turbines may be running out of runway. A fundamental change in the way a gas turbine combusts air and fuel in its core could open a path to a new era of jet engine development, however. Long pursued by propulsion researchers as a potential game-changing ...
I've also very doubtful the X37b is not big enough for a nuke, given you can put one in a 155mm or 200mm artillery shell and naval shells are being fitted with control fins and GPS to improve their accuracy.

I think there might also be some real questions about viability of any kind of high altitude bomber-like based attack. Sounds like a sitting duck for missile defenses.
Quote from: RDoc on 01/01/2017 11:07 PMI think there might also be some real questions about viability of any kind of high altitude bomber-like based attack. Sounds like a sitting duck for missile defenses.There's plenty of reason to question such an idea. Like weaponizing a Skylon, if you have the skills to do it, you have the skills to cause trouble a lot more easily and cheaply. It's a plot line from a straight-to-download thriller.
Leading development of hypersonic engines and spaceplaneshttp://www.nextbigfuture.com/2017/02/leading-development-of-hypersonic.html
Quote from: Star One on 02/09/2017 08:24 PMLeading development of hypersonic engines and spaceplaneshttp://www.nextbigfuture.com/2017/02/leading-development-of-hypersonic.htmlThat's just click-bait masquerading as a re-hash of old news and advertising. It isn't even current, making statements like:"Hypermach has completed final detail design of the first stage turbine core of a hypersonic engine. Manufacturing of this first stage has begun and is expected to be finished in 2016" -- Hello? It's 2017 already.and "Reaction Engines of the UK is a leader in developing a hypersonic vehicle and hypersonic components" -- If anyone on the planet is a "leader in developing a hypersonic vehicle and hypersonic components" it would have to be the Hyshot team, not them.No, nothing to see here.. move along!
Less than four years ago, it seemed that the U.S. Air Force was on the brink of developing the first generation of air-breathing high-speed strike weapons following the success of the experimental scramjet-powered Boeing X-51A. Now a classified report warns that the U.S. may be losing its lead in hypersonics to China and Russia. Although parallel research on hypersonic glide vehicles under DARPA’s HTV-2 program suffered failures in 2010 and 2011, the Air Force by 2013 appeared ...
Others involved in U.S. hypersonics support the report’s recommendations. Kevin Bowcutt, senior technical fellow and chief scientist for hypersonics at Boeing Research and Technology, says “many lessons on the path to X-51A success were hard-earned. Given the criticality of hypersonics as articulated in the report and with X-51A under our belt, there would be obvious value in leveraging this extensive experience and know-how to accelerate full-scale development of an operational hypersonic vehicle or weapon.”Bowcutt also believes the U.S. needs to create “a comprehensive national plan with adequate funding that fields offensive and defensive hypersonic capabilities as quickly as technology maturation, system integration and capability demonstration allow.”“It is a big problem for us. We have been kind of resting on our laurels,” says Leon McKinney, president of McKinney Associates and former executive director of the U.S. hypersonics industry team. “The U.S. has been fighting wars and terrorism, so that is one of the reasons why we have not seen a burst of capability developments. But it seems our adversaries are catching up.”McKinney backs a three-phased approach to spurring development of a boost-glide capability, starting with a focus on an offensive hypersonic system that he believes could still be fielded within three years. Development of a defensive system, which McKinney says is “tough,” would aim at characterizing Chinese and Russian vehicle maneuvering capabilities to produce a “threat tube,” to enable effective interdiction. A third element would include development of a maneuvering target vehicle “which we could engage as a simulated threat.”The report does not specify that current programs should be abandoned, “but we think there are some programmatic changes we need to see,” says Lewis. “We just say, step on the gas and move these programs forward. If you want to map out a strategy to get you from the things we have tested to an operational system, one would argue we are not on that track.”
Classified Report On Hypersonics Says U.S. Lacking Urgency
Quote from: Star One on 02/17/2017 06:36 PMClassified Report On Hypersonics Says U.S. Lacking UrgencySounds to me more like a call for more money by someone frustrated at the current lack of progress.. After all, it wouldn't be the first time in the history of aerospace that "The Russians Are Coming!" evoked a response from those holding the purse-strings.
Before anyone posts anything about hypersonic flight, they should read T. A. Heppenheimer's bookFACING THE HEAT BARRIER: A HISTORY OF HYPERSONICS (NASA-SP-2007-4232). It's probably available free from the NASA History Program website and is the best popular history of this field. Any sane person who reads this book won't be fooled by scare stories in the tabloid press about impossible Russian and Chinese hypersonic aircraft.
Well my post has been censored but it doesn't matter. I say it again (perhaps more politely) David Axe knows little about spaceflight and it is more clickbait than anything else. As for the Daily Mail it is hardly better.
I reacted to this post, more exactly to the links, which are pretty bad (a nuclear space bomber ? really ? powered by fairy dust ?)
As has been noted an X37b could carry a nuclear warhead in it's payload bay but why would it?
Weapons to fight the Goa'uld.
Or maybe there is a real threat that unbiased experts now recognize as a threat, after all it is very arrogant to doubt the advanced engineering and determination of both Russia and China to develop hypersonic weapons.
