This👇is an excellent summary of what DARPA is attempting to do with its #OpFires program. The effort is currently in Phase 3, with Phase 3B contract awarded to Lockheed Martin in January 2021. #Hypersonic Image
Similar to the US Air Force's AGM-183A #ARRW, the DARPA Tactical Boost Glide #TBG system is Government Furnished Equipment (GFE) on OpFires. While OpFires has been designed to use either of the two TBG gliders, the missile system is also designed to incorporate other payloads. Image
Under its 2021 contract for #OpFires Phase 3B, Lockheed was expected to finish its design and development activities by early January 2022. It appears that Phase 3B activity involved the last bit of work that LM needed to do before going into the flight test campaign. Image

1/12 #China asegura disponer ya de Seeker IR para los #hypersonic; interesante, pero esto trae ciertos aspectos operativos y aerodinámicos que lastraran la ventaja inherente al concepto hipersónico, es decir, si o si, la velocidad promedio y la final ha de verse reducida,

[1/15] #China’s military technology is rapidly advancing, and American companies are fueling the fire.

Last month, @Intel and @Sequoia were linked to a company contracted to provide China’s military with #AI.

That's just the tip of the iceberg.

[2/15] It’s no secret that China uses U.S. tech to create their weapons.

More than 90% of Chinese #semiconductors rely on U.S. and allied technologies and it is believed that U.S. tech contributed to China’s test of a nuclear-capable #hypersonic weapon.…
[3/15] To that end, the National Counterintelligence & Security Center (@NCSCgov) warned that China was engaged in “comprehensive” efforts to buy, copy, and steal critical and emerging tech from the United States, including semiconductors and #AIML tools.…

#SCOOP US allies are very concerned that @JoeBiden is considering a landmark shift in nuclear policy that would undermine the #NuclearUmbrella that protects them, as #China rapidly expands its military, including nuclear-capable #hypersonic weapon
France, Germany, UK, Japan, Australia and others have told US they are opposed to "No First Use" and "Sole Purpose" nuclear policies. Some are worried that Biden not aware of their opposition. (Me and @HenryJFoy)

SCOOP – #China has stunned US intelligence and military officials by testing a #nuclear capable #hypersonic missile that traveled through low orbit in space, making a full circle around the globe before speeding towards its target.
Missile missed target by couple of dozen miles, but people familiar with the test say China demonstrated a stunning capability that nobody thought they already had mastered. Image

Happening now: "The president deals w/the world as it is-we deal w/dictators & authoritarian regimes as they are, not as we hope them to be" US Nat'l Security Adviser @robertcobrien tells @HudsonInstitute

"He's done the hard work of strengthening our alliances & in doing so has put substance over style, & he's been criticized for that" he adds

Happy 10th Anniversary to the @Boeing X-51A Waverider! This collab. led by @AFResearchLab also included @DARPA & @NASA, producing a scramjet-powered #hypersonic test platform that first flew #OTD 10 yrs ago, flying at Mach 5 for over 2 minutes! That is 1 mile per second! #AvGeek
The X-51 was air-dropped from a B-52 & propelled by a rocket booster to Mach 4.5, then the booster would separate and the scramjet would kick in.

This is the classic scramjet figure you always see. If you’re moving fast enough you can compress with shocks not a turbine!
The program saw four unmanned test flights, two of which (1 & 4) were successful. The X-51 program concluded on a high note as the 4th flight set a record for the longest air-breathing hypersonic flight of 210 seconds at Mach 5.1! Flight ended when fuel was exhausted.
