Raytheon, an RTX entity, achieves a significant milestone in the Hypersonic Air Launched Offensive Anti-Surface (HALO) program, as it completes a successful technical review and seamless prototype fit-check for the U.S. Navy. HALO, a carrier-based hypersonic missile, enhances the Navy's capabilities in contested battlespaces. Leveraging advanced digital engineering, Raytheon's HALO prototype progresses swiftly, with a successful fit check on an F/A-18 ensuring compatibility with existing Navy aircraft. This development underscores RTX's commitment to delivering proven technology promptly, addressing evolving threats in anti-access/area denial environments.


In the arid landscape of Tucson, Arizona, a technological tempest is brewing as Raytheon, under the RTX banner, advances its role in shaping the future of naval warfare. The completion of a technical review and seamless prototype fit-check heralds a significant stride in the U.S. Navy's Hypersonic Air Launched Offensive Anti-Surface (HALO) program.

HALO stands as a beacon of innovation, a high-speed missile designed to empower the Navy in navigating contested battlespaces, particularly in anti-access/area denial environments. The program aligns with the Navy's long-range fires strategy, providing a crucial edge in anti-surface warfare capabilities.

Raytheon's approach to HALO is a symphony of digital and model-based engineering techniques. The fusion of digital and physical design concepts and models, achieved in a remarkably short time, propels the missile's development forward. This prowess expedites the realization of a technologically advanced HALO prototype, a testament to Raytheon's commitment to staying at the forefront of hypersonic advancements.

A pivotal moment in the HALO journey was the successful fit check on an F/A-18, a Navy Super Hornet aircraft. This crucial step ensures that the HALO prototype seamlessly integrates with existing Navy aircraft and support equipment. The compatibility check, conducted in the fall, validates the versatility and adaptability of HALO within the Navy's operational framework.

Colin Whelan, president of Advanced Technology at Raytheon, emphasizes the urgency in delivering proven technology to meet the evolving threats faced by warfighters. Raytheon's expertise in hypersonics aligns with the Navy's need for a mature and digitally engineered system, reflecting a commitment to pace and precision.

Raytheon secured the HALO contract's phase one in March 2023, and the progress made in Tucson charts a promising trajectory for the program's future. As the HALO missile inches closer to deployment, Raytheon's dedication to advancing hypersonic technology echoes its century-long commitment to enhancing defense capabilities.


In the boundless skies of defense innovation, Raytheon, within the RTX consortium, emerges as a trailblazer with HALO, a hypersonic marvel that promises to redefine naval warfare. The completion of the technical review and prototype fit-check amplifies the resonance of Raytheon's commitment to delivering cutting-edge technology to safeguard national security. As HALO progresses, it brings with it the assurance of a formidable defense against emerging threats, marking yet another chapter in Raytheon's legacy of excellence.
