That said, does anyone really believe that Boeing is really serious about bringing such a thing to market for commercial travel? I'm asking honestly, I don't know the first thing about the intentions or business case for such a bird but the lessons of Concorde are pretty much commercial aerospace canon at this point so it would seem to me that heavy dose of skepticism is more than reasonable. I'd love to be wrong, but what makes anyone think this is a genuine effort to bring this craft into the market? As I said a few sentences ago, I'm very interested/hopeful for things like this, but count me as a non-believer in this press release, I believe it when they deliver some to a customer (USG doesn't count).Concorde shows that there is a small market for fast first last travel across the Atlantic. About a half filled Concorde from London to New York per day.Class of service split is very price elastic. The market was that size at the Concorde fare point. But many many Concordes worth of passengers cross that way every day. It's not clear that the market at, say 20% higher[1] than a base economy fare is sitll 1/2 a Concorde. 1 - this premium is not necessarily reasonable, it may be higher, but if you compare Concorde fares to base economy fares of the day it was more like a 5X premium or more, not a 1.2X premium....

These kind of releases really irritate me -- Boeing offered nothing in terms of actual seating, range, how it would be powered, or even any kind of specific timeline.
All the release had was a render for something that will certainly change radically in the two decades of its development.I suppose Boeing's marketing department should be congratulated for getting so much attention for one JPEG.
Lockheed Martin has secured another hypersonic weapon-related contract, with a $40.5 million U.S. Navy award for booster technology development. This follows the April award of a U.S. Air Force contract, potentially worth $928 million, to develop a hypersonic strike missile for fielding by 2022.The latest Hypersonic Booster Technology Development (HBTD) contract, awarded by the Navy’s Strategic Systems Program, may be related to the Tactical Boost Glide (TBG) weapon that Lockheed’s Skunk Works is developing for DARPA. The air-launched, rocket-boosted missile demonstrator is scheduled to fly in 2019.The request for proposals for HBTD refers to a “hypersonic glide body.” This sounds similar to TBG, which is a 500-nm-range unpowered glider accelerated to hypersonic speed by a rocket booster. DARPA’s fiscal 2019 budget request indicates the agency plans to develop a ship-launched version.In addition to the TBG, the Skunk Works is under contract to develop DARPA’s Hypersonic Air-breathing Weapon Concept (HAWC), an air-launched, scramjet-powered missile demonstrator also scheduled to fly in 2019. Raytheon is also under contract to build a HAWC demonstrator.Lockheed’s April contract, meanwhile, covers development of the Hypersonic Conventional Strike Missile (HCSW, pronounced “Hacksaw”), a simpler air-launched, rocket-powered weapon intended for more rapid development to arm existing Air Force fighters and bombers.Lockheed also is working on the Air-launched Rapid Response Weapon (ARRW, pronounced “Arrow”), a hypersonic boost-glide weapon being developed for the Air Force under an extension to the DARPA contract for TBG. ARRW and HAWC may be potential follow-ons to HCSW.

You mentioned hypersonics as another area that involves prototyping. Can you say more about that?Hypersonics is an area that I’m very passionate about. I feel like we need to not fall behind any country in this domain. And it was an area, coming in from SCO, I really wanted to dive into these prototyping efforts and see is there anything that we can do to speed them up.And in fact, there is. This is another example of another program where the rapid authorities appear to make a big difference on how quickly you can go. But the big difference is really shifting the program so that it embraces the potential for failure. You saw this a lot from me at my last job. Failure is very much an option, and as a matter of fact, if we’re going to fail and we do it early in a program, we’ve probably learned something valuable that we need to understand before progressing
But a new document reveals that the USAF awarded a separate deal to Lockheed’s Missiles and Fire Control division in July 2017 to rapidly develop and field the Air-launched Rapid Response Weapon (ARRW, pronounced “Arrow”).The ARRW, now assigned the designation AGM-183A, evolves from the Tactical Boost Glide (TBG) programme launched in 2014 by the Defense Advanced Research Projects Agency (DARPA). By using a rocket to boost the missile to very high altitudes, the unpowered ARRW then glides down to lower altitudes at speeds up to Mach 20.
The test of the unmanned system, designated Starry Sky 2, took place recently in Northwestern China, reports the official China Daily newspaper.During the flight the vehicle reached an altitude of 30km and undertook several maneuvers.The wedge-shaped vehicle was initially lifted by a solid propellant rocket, before detaching and performing its flight. China Daily reports that the aircraft is a “waverider,” using its own shock waves to generate lift.

IOW it could have been done anytime in the last 4 decades.
As China announces tests of another hypersonic vehicle, the U.S. Air Force is revealing new details of its accelerating hypervelocity weapons development strategy as well as concepts for potential space-based surveillance systems to provide early warning. The Chinese vehicle, dubbed Starry Sky 2, was tested on Aug. 3 at Mach 5.5-6 at an altitude of 100,000 ft. Launched by rocket from the ground, and developed by the China Academy of Aerospace Aerodynamics, it is a waverider design that ...
The veil of secrecy has lifted over one of the Pentagon’s largest hypersonic weapons programs, revealing new details of a triservice rush to adapt a nearly 40-year-old experimental maneuvering reentry vehicle concept into an air-, sea- or land-launched common-boost-glide weapon. The revelations provide deeper insight into plans to unite three separate projects—the U.S. Army’s Advanced Hypersonic Weapon (AHW), the Air Force’s Hypersonic Conventional Strike Weapon ...
PENTAGON The Navy is refitting its decades-old China Lake weapons testing and research site in the Mojave Desert to begin hosting hypersonic weapons testing from a variety of platforms, including undersea launchers.A notice posted on a government contracting Website Tuesday night offered the first concrete evidence that the Pentagon is moving ahead on ambitious plans to develop a variety of weapons that can streak through the atmosphere and strike any target on the globe within an hour. The program, dubbed Conventional Prompt Strike, is a Pentagon-wide effort the Navy is taking a central role in developing, though no firm dates on the start of testing have been offered.Part of the work being announced at China Lake fits into this plan, as there is a call for “conceptual design and operation” of an Underwater Test complex “which will include estimated costs, technology maturity and estimates on build schedules.”
Defense contractor Raytheon just signed a $63.3 million contract with the Defense Advanced Research Projects Agency (DARPA) to develop a “tactical boost glide” (TBG) hypersonic weapons program.The weapon system could reach hypersonic speeds of up to five times the sound barrier thanks to a rocket engine. A payload will then glide the rest of the way to the intended target — completely unpowered, without the ability to accelerate again. But operators will be able to maneuver it from a distance.
Lockheed’s booth at the Air Warfare Symposium this evening features an unlabeled hypersonic glide vehicle. It appears to be HTV-2. Not, sadly, ARRW or TBG.
The @AFResearchLab, which is having a busy week, released a new video showing the X-60A concept for a liquid fuel rocket testbed for hypersonic flight conditions. The X-60A also just passed a critical design review.
The US Air Force’s X-60A hypersonic research vehicle completed its critical design review.The programme is now moving into the fabrication phase, with the initial flight of the vehicle scheduled to take place in about a year at Cecil Spaceport in Jacksonville, Florida, says the USAF. The liquid-rocket powered vehicle is designed to be launched after being dropped from under the belly of a NASA C-20A, a military version of the Gulfstream III business jet.
