Navy Validates Sea-Based Hypersonic Launch

The U.S. Navy's Strategic Systems Programs is continuing on the path toward the nation's first sea-based hypersonic fielding with a successful end-to-end flight test of a conventional hypersonic missile from the Cape Canaveral Space Force Station, Florida. This test marked the first launch of the Conventional Prompt Strike (CPS) capability utilizing the Navy's cold-gas launch approach that will be used in Navy sea-based platform fielding.

"The speed, range, and survivability of hypersonic weapons are key to integrated deterrence for America," Secretary of the Navy John Phelan said. "When fielded, Conventional Prompt Strike will deliver unmatched capabilities to our warfighters."

Cold-Gas Launch

U.S. Navy Strategic Systems Programs conducts a cold-gas launch of a conventional hypersonic missile on the path to Navy fielding in Cape Canaveral, Fla. This test informs the Navy fielding approach for the Conventional Prompt Strike offensive hypersonic capability, as well as the continued development and production of the common hypersonic missile that is being developed in partnership with the U.S. Army.

This test was the next step in the Navy's flight testing program of the common All Up Round (AUR) that is being developed in partnership with the Army's Rapid Capabilities and Critical Technologies Office. In 2024, the programs completed two additional end-to-end flight tests of the AUR that will be fielded to both the Navy and Army.

"The cold-gas approach allows the Navy to eject the missile from the platform and achieve a safe distance above the ship prior to first stage ignition. This technical achievement brings SSP one step closer to fulfilling our role of providing a safe and reliable hypersonic capability to our Navy," said Vice Adm. Johnny R. Wolfe Jr, Director, Navy's Strategic Systems Programs, which is the lead designer of the common hypersonic missile.

The CPS Program has been diligently planning and executing engineering and test efforts to prepare for the first Navy fielding aboard the USS ZUMWALT. Utilizing an In-Air Launch test facility, the Program conducted an extensive test campaign to validate the launch approach prior to the completion of this flight test. Information gathered from this test will inform the continued development and production of the AUR and the first use of this cold-gas launch approach on a surface ship platform.

The rapid development and demonstration of conventional sea-based hypersonic strike weapon systems supports the U.S.'s ability to deter, and if necessary, defeat potential strategic competitors. The range, accuracy, lethality, and survivability of hypersonics is a significant leap-ahead in U.S. conventional strike capabilities, complementing existing capabilities and enabling the U.S. to defeat adversary high-end capabilities.
