HAWC (Hypersonic Air-breathing Weapon Concept) ha volato ... ma i risultati dell'esperimento sono stati tenuti segreti ...


DARPA, in partnership with the U.S. Air Force, completed a free flight test of its Hypersonic Air-breathing Weapon Concept (HAWC) last week. 
The missile, built by Raytheon Technologies, was released from an aircraft seconds before its Northrop Grumman scramjet (supersonic combustion ramjet) engine kicked on. 
The engine compressed incoming air mixed with its hydrocarbon fuel and began igniting that fast-moving airflow mixture, propelling the cruiser at a speed greater than Mach 5 (five times the speed of sound).
The HAWC vehicle operates best in oxygen-rich atmosphere, where speed and maneuverability make it difficult to detect in a timely way. 
It could strike targets much more quickly than subsonic missiles and has significant kinetic energy even without high explosives.
"The HAWC free flight test was a successful demonstration of the capabilities that will make hypersonic cruise missiles a highly effective tool for our warfighters,” said Andrew "Tippy" Knoedler, HAWC program manager in DARPA's Tactical Technology Office. 
"This brings us one step closer to transitioning HAWC to a program of record that offers next generation capability to the U.S military."

Perplessità ...


North Korea tested a missile it called the Hwasong-8 “strategic weapon” Sept. 28, suggesting later that it was a hypersonic missile - but the Pentagon said it’s unclear exactly what Pyongyang flew and that it doesn’t change U.S. military posture in the Western Pacific.
Gen. Glen D. VanHerck, head of U.S. Northern Command, told Pentagon reporters Sept. 30 that the U.S. Intelligence Community is “still making an assessment” of what was tested, which he said North Korea has claimed was a hypersonic missile.
“We’ll just have to see,” he said, but even if the conclusion is that the vehicle tested was a true hypersonic glide vehicle, it doesn’t pose a threat the U.S. can’t defend against.
“It would be my assessment that the homeland would be safe and secure” from a North Korean hypersonic missile, Van Herck asserted. 
He did not speculate on the threat to U.S. forces on the Korean Peninsula.

AGM-183A Air-Launched Rapid Response Weapon (ARRW) ... fallito pure il terzo test ... cosa che a Russi e Cinesi non spiacerà di certo ...


Il terzo volo di prova del razzo ipersonico AGM-183A (Air-Launched Rapid Response Weapon, ARRW) si è rivelato un fallimento proprio come i test precedenti, e le cause non sono state ancora del tutto identificate, secondo quanto riferito dal general di brigata del'aviazione statunitense Heath Collins alla rivista War Zone (*).

E' di primaria importanza che il tracciamento a infrarossi dei missili ipersonici sia effettuato ancor più vicino alla Terra, dall'orbita terrestre bassa ...


A satellite constellation specially suited to tracking hypersonic missiles could be up and running by 2025.
Director of the Space Development Agency Derek M. Tournear laid out the advantages of the Tracking Layer of SDA’s still-envisioned National Security Space Architecture in a virtual talk Jan. 12 hosted by the Mitchell Institute Spacepower Advantage Center of Excellence.  
Tournear explained that maneuverability has brought about the need for infrared tracking to be done closer to Earth, from low Earth orbit (LEO) in addition to the 40,000-kilometer-high orbits where missile tracking takes place now. 
DOD’s existing tracking systems in high geosynchronous Earth orbit (GEO) and polar orbit can detect the launches, but maneuverability has introduced the need to also track missiles throughout their flight, Tournear said. 
His comments come one day after North Korea claimed to have tested another hypersonic missile. 
Although the U.S. refers only to the missile as “ballistic,” officials agree the missile launched Jan. 11 is more advanced than one launched just a week earlier.

Anche le armi ipersoniche sono presenti nella lista delle massime priorità della Sottosegretaria alla Difesa Heidi Shyu ...


Artificial Intelligence, integrated networks, hypersonics, and microelectronics are among the top priorities for Heidi Shyu, undersecretary of defense for research and engineering. 
In a wide-ranging discussion with reporters Jan. 13, Shyu also said hypersonics test capacity will see a big boost in the fiscal 2023 program objective memoranda and that a major experiment in joint all-domain command and control will take place in February, connecting platforms from all the services.
Shyu said she had planned to reduce the 11 top priorities created by the previous administration.
“I thought I could neck it down quite a bit, but I sort of failed, and I think I’ve ballooned it instead,” she said. 
The new list should be published soon. 
Shyu didn’t want to get ahead of the announcement but mentioned “trusted AI” and integrated networks as high on the list. 
The latter is necessary “to use autonomy on an unmanned system,” she said. 
She also mentioned hypersonics and microelectronics, which were the top two under the previous administration.

E' stato siglato un accordo fra Hypersonix Launch Systems Ltd. e Kratos Defense & Security Solutions, Inc. per lo sviluppo e la sperimentazione del dimostratore di tecnologia per droni ipersonici multi-missione DART AE.



Hypersonix Launch Systems Ltd. and Kratos Defense & Security Solutions, Inc. have signed an agreement to launch the DART AE multi-mission hypersonic drone technology demonstrator. 
In the Hypersonix Kratos Team’s (the “Team”) submission to the Australian Department of Industry, Science, Energy and Resources Modern Manufacturing Initiative (MMI) Grants Program 2, the Team is planning for a launch and initial demonstration flight of the DART AE Hypersonic Drone System in 2023. 
The Hypersonix DART AE, a multi-mission, hypersonic drone, will be fully 3D-printed out of exquisite high-temperature materials and powered by a single, fifth-generation SPARTAN, zero emission, clean hydrogen scramjet engine with a publicly disclosable range of 500km.
