In an interview, David Wright, a physicist at the Massachusetts Institute of Technology and an author of the new analysis, called the superweapon a mirage. “There’re lots of claims and not many numbers,” he said. “If you put in the numbers, you find that the claims are nonsense.”

Original Paper:
Modelling the Performance of Hypersonic Boost-Glide Missiles
Cameron L. Tracy and David Wright, "Modelling the Performance of Hypersonic Boost-Glide Missiles," Science & Global Security, vol. 28, no. 3 (2020)
The United States, Russia, and China are developing an array of hypersonic weapons--maneuverable vehicles that carry warheads through the atmosphere at more than five times the speed of sound. Proponents claim that these weapons outperform existing missiles in terms of delivery time and evasion of early warning systems. Here, we report computational modelling of hypersonic boost-glide missile flight which shows that these weapons travel intercontinental distances more slowly than comparable ballistic missiles flying depressed trajectories, and that they remain visible to existing space-based sensors for the majority of flight. Fundamental physical limitations imposed by low-altitude atmospheric flight render hypersonic missiles an evolutionary--not revolutionary--advancement over established ballistic missile technologies. Misperceptions of hypersonic weapon performance have arisen from social processes by which the organizations developing these weapons construct erroneous technical facts favoring continued investment. The modelling reported here provides a basis for rigorous, quantitative analysis of hypersonic weapon performance.

WEST PALM BEACH, Fla., Jan. 25, 2021—Sikorsky, a Lockheed Martin Company (NYSE: LMT), and Boeing (NYSE: BA) today released details of its advanced helicopter for the U.S. Army's Future Long Range Assault Aircraft competition, known as FLRAA. The aircraft, named DEFIANT X, will be the fastest, most maneuverable and most survivable assault helicopter in history. Combined with the team's unsurpassed experience in mission systems, training and sustainment, it will revolutionize the way the Army meets threats in 2035 and beyond.
DEFIANT X is a complete weapon system that builds on the handling qualities and transformational capabilities proven by the team's technology demonstrator, SB>1 DEFIANT®. With unmatched range and survivability, DEFIANT X will to fly low and fast through complex terrain, land quickly, deliver soldiers and equipment to the objective area (referred to as "the X") and get out.
DEFIANT X flies twice as far and fast as the venerable Black Hawk helicopter it is designed to replace. Currently undergoing testing in a digital combat environment, the aircraft continues to prove itself the most survivable platform for mission requirements.

"We are ready to deliver unparalleled capabilities backed by proven technologies that will truly transform the Army's mission today – with room to grow and adapt to the missions of tomorrow," said Andy Adams, Sikorsky vice president of Future Vertical Lift. "DEFIANT X not only includes the transformational aircraft, mission systems and revolutionary sustainment solution, but also leverages Sikorsky's and Boeing's advanced manufacturing capabilities."
With its rigid coaxial rotor system and pusher propeller, DEFIANT X incorporates Sikorsky X2 Technology™ to operate at high speeds while maintaining low-speed handling qualities. This critical capability provides soldiers with increased maneuverability and survivability in high-threat air defense environments, allowing them to penetrate enemy defenses while reducing exposure to enemy fire.
"DEFIANT X is purpose-built for a modernized Army that requires expanded reach, survivability and lethality," said Steve Parker, vice president and general manager of Boeing Vertical Lift. "This weapon system will give soldiers unequaled technological advantage and connectivity over adversaries in a multi-domain battle space."
DEFIANT X will revolutionize the Army's air assault capability with limited changes in tactics, techniques, procedures, training and infrastructure while maintaining the Black Hawk helicopter footprint and tight formation capability flown today.
The Army is expected to release a request for proposal on FLRAA later this year, with a contract award expected in 2022.

About Sikorsky and Boeing
Together, Sikorsky and Boeing have built 90 percent of the U.S. Army's current military rotorcraft and have totaled more than 15 million flight hours. We're the team that has brought forward iconic military rotorcraft including: Black Hawk, Chinook and Apache. The iconic UH-60 Black Hawk has proven itself to be the premiere assault platform in the world and DEFIANT X will bring the next level of capability that the Future Long Range Assault Aircraft requires.
Researchers at Brown University have developed a new way to make super-hard metals. The team made nanoparticle "building blocks" that could be fused together under moderate pressure, thanks to a chemical treatment.
