HAWC 'complete flight tests in 2020'?The following is the Aug. 26, 2020 Congressional Research Service report Hypersonic Weapons: Background and Issues for Congress. From the report The United States has actively pursued the development of hypersonic weapons—maneuvering weapons that fly at speeds of at least Mach 5—as a part of its...news.usni.org
Next Generation Land Attack Weapon (NGLAW)
Next Generation Land Attack Weapon (NGLAW) will provide the next generation of long-range, kinetic strike capability to destroy high-priority fixed, stationary and moving targets – as well as those targets hardened, defended or positioned at ranges such that engagement by aviation assets would incur unacceptable risk. NGLAW will be capable of kinetic land and maritime attack from both surface and sub-surface platforms.
The NGLAW AoA (Analysis of Alternatives) has completed and the classified results have been shared with all four congressional defense committees.
Offensive Anti-Surface Warfare (OASuW) Increment 2
OASuW Increment 2 is required to deliver the long-term, air-launched ASuW capabilities to counter 2028 threats (and beyond). The Department continues to plan for OASuW Increment 2 via full and open competition. To inform the long-term path forward, the DoN will leverage the NGLAW AoA results to inform the required ASuW capabilities. The AoA study to determine the Increment 2 path-forward will complete in 3rd Qtr FY 2020. In the interim, the Navy is pursuing incremental upgrades to LRASM to bridge the gap to OASuW Increment 2 program of record. Increment 2 IOC is planned for the FY 2028-2030 timeframe.
Rhoads [director of the Ray W. Herrick Laboratories and professor of mechanical engineering] said there are currently 18 research projects and groups conducting energetics research as part of the project. Among the research projects:
"It's an interesting project. On the one hand, it's trying to increase the effectiveness of these weapons, and on the other, it's trying to increase the safety and sustainability," Rhoads said.
- Gaining a better understanding of how shockwaves interact with the microstructure and defects in energetic materials.
- Improving the performance of materials used in the aggressive service conditions such as gun launch and hypersonic flight.
- Developing inkjet-printed conductive energetic materials.
- Developing new manufacturing techniques to encapsulate metal or composite materials with embedded sensors to develop health-monitoring smart armor.

I'd imagine these hypersonic air-breathing developments means they're finally peeling the curtain back on some things to stimulate the industrial base/collective brain trust.

In the test of March 19 it reached the speed of mach 17, but I think it can also go faster if they launch it from further away, as with the test in 2014 from the island of Kodiak in Alaska to Kwajalein in the Marshall Islands, which however exploded at the moment of launch.The velocity will continue to bleed during the glide. So I suspect we are, among other things, seeing average speed conflated with max speed at burnout. Still, all of those seem higher than I would have thought. The 2017 test covered 2200 miles in under 30 minutes, which works to an average of ~Mach 6. But it would be the case that the longer the flight, the lower the average speed. I doubt we will ever truly know the envelope for the weapon, and I feel after you reach a certain threshold the difference is a little moot.
EDIT: is IR CSP a separate program/different missile than CSP? Or did it just get renamed?
Those aren't the LRASM-B design. The design was different and the program was cancelled about 5 minutes after they announced it years ago.
Yes. Boeing stresses that both hypersonic missiles (boost-glide and airbreather) depicted are 'generic' designs based on unclassified dataThose aren't the LRASM-B design. The design was different and the program was cancelled about 5 minutes after they announced it years ago.
Dare, i say it again arrw is 7300 lbs..What on Earth are you on about?Well, i said something about the matching dimensions as well. Arrw literally is the same length/diameter as this, and it won't be entirely dubious to assume its weight as identical as well.Did you READ the link? AGM-183 is a Lockheed Martin product. "And Boeing showed a “multipurpose booster” on centerline on #AWS20 display model, weighing 7,300lb and 270-in long." This is the Boeing missile they're referring to:View: https://mobile.twitter.com/TheDEWLine/status/1233523377782054912Any chance of a link? I don't recall seeing either a weight or length given for AGM-183.Umm.. Roper?!Who's to say AGM-183A weighs 7,000lbs?
7,300 lbs, 270"x30" was quoted..
Also, those dimensions match the ones deduced from the pic from B52 flight tests, so i don't see the mass deviating too much from whats announced.
Also, considering other solid rockets on various missiles of similar size(atacms on x51, iskander/kinzhal, df-11, skybolt), this seems the appropriate mass based on these dimensions.

Given that many of the BGVs* are already wrapped in plasma, "conventional" MHD techniques strike me as making far more sense.For decades, the DoD has been researching a radical drag reduction technique that involves sheathing a vehicle in directed energy-induced plasma.www.thedrive.com
