Furientis

Furientis manufactures interceptor missiles and solid-rocket motors engineered from day one for high-rate production, addressing critical shortfalls in U.S. naval defense munitions. The company vertically integrates seeker, controls, airframe, and propulsion subsystems, using a proprietary solid rocket motor chemistry and software-defined multimodal seekers built from commercial off-the-shelf components. Flight-testing ship-based interceptors today, Furientis targets a 30-minute final assembly process and a monthly design-build-fly cadence.

Problem

Current U.S. defense munitions production is limited to a few hundred ship-borne interceptors per year, far below the thousands needed to sustain modern naval operations and to replace losses in prolonged conflicts. In 2024, U.S. Navy ships fired more than 200 interceptors defending against Red Sea threats, exceeding the nation's annual production capacity and drawing down stockpiles at an unsustainable rate.

Solution

Furientis designs and manufactures cost-effective, high-volume precision-guided interceptors and solid-rocket motors that can be produced at scale in existing factories. Their software transforms commodity components into a multimodal seeker stack, providing robust guidance without bespoke parts. The propulsion chemistry and manufacturing processes are optimized for thousands of units per factory annually, enabling a 30-minute final assembly line and a monthly design-build-fly cadence. By focusing on manufacturability from day one, Furientis delivers a rapid feedback loop that shortens development cycles and accelerates fielding of new interceptor variants. The approach aims to close the gap between demand and supply for ship-side defensive missiles.

Target Audience

Primary customers are naval forces and defense acquisition programs, including the U.S. Navy and U.S. Army, that require large quantities of ship-borne interceptors, as well as defense contractors seeking a scalable source of precision-guided munitions.
