Raytheon has successfully completed a technical review and a seamless prototype fit-check in phase one of the U.S. Navy's Hypersonic Air Launched Offensive Anti-Surface (HALO) program. HALO is a carrier-based high-speed missile that will allow the Navy to operate in and control contested battlespaces in anti-access/area denial environments and will support their long-range fires strategy. Digital and physical design concepts and models of Raytheon's HALO prototype were created in a matter of months using digital and model-based engineering techniques.

This approach is accelerating the development of the HALO missile. A successful fit check on an F/A-18 was held in the fall, ensuring that the prototype is compatible with the Navy's Super Hornet aircraft and existing support equipment. Raytheon was awarded a phase one HALO contract in March 2023.

Work on this program is being completed in Tucson, Arizona.
