Maketa nove hipersonicne rakete velikog dometa, predstavljena juce 27. februaru u Vasingtonu.



Jedna baterija bi trebalo da se sastoji od komandne stanice i 4 lansera sa raketama koje bi letele preko 3800 milja na sat. Test letovi se ocekuju sledece godine a prva baterija tokom 2023.



Citat:In March 2019, the Secretary and Chief of Staff of the Army directed the accelerated delivery of a prototype ground-launched hypersonic weapon with residual combat capability by Fiscal Year (FY) 2023. To execute this strategy, the Army Rapid Capabilities and Critical Technologies Office (RCCTO) has selected two prime contractors to build and integrate components of the LRHW prototype.

On August 29, the Army awarded an Other Transaction Authority (OTA) agreement to Dynetics in the amount of $351.6 million to produce the first commercially manufactured set of prototype Common-Hypersonic Glide Body (C-HGB) systems. Also on August 29, the Army awarded a second OTA agreement to Lockheed Martin in the amount of $347.0 million as the LRHW prototype system integrator.

The Army RCCTO is responsible for delivering the prototype LRHW battery, consisting of four trucks with launchers, hypersonic missile rounds, and a command and control system. The OTA awards support the design, integration and production work that enables a series of flight tests beginning next year, leading to fielding in FY23.

In developing the LRHW, the Army is working in close collaboration with the other services through a Joint Service Memorandum of Agreement on hypersonics design, development, testing and production. As part of the agreement, the Army will execute production of the C-HGB for all services, while the Navy will lead the glide body design beginning in FY20. This joint cooperation allows the services to leverage technologies, while tailoring them to meet specific air, land and sea requirements.

The two contract awards mark an important step in transitioning the development of Army hypersonic capabilities out of the government laboratories and into commercial production. Initially, Dynetics will work with Sandia National Laboratories to learn build of the glide body.

Prvi(novi) test u trecem kvartalu sledece godine
Citat:
But looking forward, “our next flight test will be in third quarter ’21. Then we have additional flight tests in first quarter ’22,” Thurgood told me. “We have five more flight tests – at least five more flight tests – before we build in fourth quarter ’23.”

Tests will not only come closer together. They’ll also become more demanding.

“We are working to make it more accurate and survive in a more stressful environment,” said Thurgood’s deputy for hypersonics, Robert Strider. “With every test that we do, we’re increasing the test envelope to make sure that it will work as designed.”


Citat:That initial test in 2011 – using a larger and less refined version of the glide body – was simply about proving the design could survive the flight profile: extreme acceleration from the booster, the heat of air friction as it ripped through the atmosphere, the vacuum of near space, and reentry coming down. The failed 2014 test, and the 2017 test that replaced it, began to explore accuracy, lethality, and other performance characteristics. The future tests focus on fine-tuning the design to perform precisely as the Army and Navy missions require.

“As we hone in further and further on refining our operational outcomes, the [test] objectives become more narrow in their scope,” Thurgood told me. “We know over the next five tests exactly the outcomes we need to test to.”

In parallel to the flight test program, the Army is also trying to build an industrial base from scratch. All the glide bodies tested so far have been built, one at a time, at the Energy Department’s Sandia National Laboratories, which invented the design. That’s not a viable model for mass production.

“The glide body technology is solely owned by the government,” Thurgood told me. “They’re currently produced – ‘made’ is probably a better word. It’s not really a production line – they’re really handmade by the great folks out at Sandia. [But] obviously how the great PhDs at Sandia make a thing may not be how we commercially make a thing.”

Citat:
LtGen Neil Thurgood today narrates a video of Flight Experiment-2 from March, including blast impact down range. He declines to provide accuracy, but President Trump said last month that the impact was 14 inches from the “center point.”
