KAUAI, Hawaii — The Department of Defense has achieved a decisive flight milestone for the Common Hypersonic Glide Body, advancing joint Army and Navy development programs aimed at fielding operational prompt-strike capabilities by 2023.
KAUAI, Hawaii — Launching from the Pacific Missile Range Facility in Barking Sands, Hawaii, the joint U.S. Army and Navy test team successfully flight-tested the Common Hypersonic Glide Body (C-HGB), validating the weapon’s aerothermal protection, internal guidance systems, and maneuver control surfaces at speeds exceeding Mach 5.
The flight test, designated Flight Experiment 2, demonstrated the weapon’s capability to launch aboard a standard two-stage solid rocket booster, detach at the edge of space, and glide through the upper atmosphere at hypersonic velocities while executing planned lateral maneuvering maneuvers before impacting a designated target point thousands of miles downrange.
Closing the Great-Power Hypersonic Gap
The successful test comes amid growing bipartisan urgency in Congress over Russian and Chinese hypersonic weapon deployments. Beijing’s fielding of the DF-17 medium-range missile and Moscow’s deployment of the Avangard strategic boost-glide vehicle have raised alarms inside the Pentagon regarding the vulnerability of carrier strike groups and forward airbases in the Indo-Pacific.
Unlike traditional ballistic missiles, which follow predictable parabolic trajectories easily tracked by early-warning radars, hypersonic boost-glide vehicles fly in the upper atmosphere beneath missile defense radar horizons while retaining the aerodynamic ability to maneuver around defensive interceptor envelopes.
Industrial Base and Material Bottlenecks
While Pentagon acquisition executives lauded the flight test results, defense industrial analysts warn that manufacturing capacity remains the program’s primary bottleneck. Fielding hypersonic batteries at scale requires specialized carbon-carbon composite nose tips capable of withstanding temperatures exceeding 3,000 degrees Fahrenheit, as well as hardened radio-frequency transceivers able to communicate through ionization plasma sheaths.
Under the Defense Production Act Title III authorities, the Pentagon is directing hundreds of millions of dollars into domestic advanced manufacturing facilities and modernizing national aerothermal wind tunnels to ensure that prototype successes translate into resilient inventory depth for combatant commanders.
