X-Bow to build boosters for CoAspire’s CHAOS cruise missile

CoAspire selected X-Bow Systems to develop and produce solid-rocket boosters for the ground-launched cruise missile being developed under the U.S. Navy's CHAOS programme. The booster will launch and accelerate the RAACM-ER missile before its turbojet sustains flight, supporting a weapon intended for maritime and land attack. CoAspire received a $70 million prototype agreement in July 2026 covering programme Phases 1 and 2, including design, construction, testing and delivery. X-Bow's subcontract value, quantities and delivery schedule were not announced, while CHAOS is intended to provide an affordable strike option for allies through Foreign Military Sales.
