Kratos Expands Production of Spartan Engines to Support Growing Missile and Loitering Munition Demand

U.S.-Designed, U.S.-Manufactured Propulsion Systems Deliver Industry-Leading Performance at Affordable Cost

SAN DIEGO, June 9, 2026 (GLOBE NEWSWIRE) — Kratos Defense & Security Solutions, Inc. (Nasdaq: KTOS), a technology, products, system and software company in defense, national security, and global markets, today announced plans to significantly increase production capacity for its Spartan line of turbojet engines to support growing demand across missile and loitering munition programs.

The Spartan line of engines delivers military-grade performance while maintaining the affordability and production scalability required to support today’s evolving national security environment. Designed to provide exceptional thrust, reliability, and operational capability at commercial prices, Spartan engines are currently supporting multiple customers and platforms across the defense sector.

To meet increasing demand, Kratos is expanding production to produce 3,000 engines next year. To accelerate delivery timelines and support customer requirements, the company has already initiated internally funded long-lead material procurement and strategic supply chain investments, ensuring production readiness and minimizing future lead times.

“As the Department of War focuses on rebuilding critical missile inventories and increasing affordable precision-strike capacity, the need for scalable, high-performance but low-cost propulsion systems has never been greater,” said Steve Fendley, President of Kratos Unmanned Systems Division. “Kratos is investing today to ensure our customers have access to affordable, reliable, American-made propulsion systems that can be delivered at the speed and scale required by the modern threat environment.”

The Spartan family of engines is designed, manufactured, and supported entirely in the United States, utilizing a domestic supply chain that strengthens the U.S. defense industrial base while reducing reliance on foreign sources for critical propulsion technologies.

Kratos’ investments directly support Department of War priorities to replenish missile inventories, expand production capacity for precision-strike weapons, and deliver affordable mass across the Joint Force. The company’s proactive investments in manufacturing capacity and supply chain readiness position Kratos to rapidly support emerging requirements while helping strengthen America’s long-term defense production capabilities.

With growing demand across missile, loitering munition, and autonomous system programs, Kratos’ expanding Spartan engine production capability reinforces the company’s commitment to delivering affordable, mission-ready propulsion solutions that support U.S. and allied national security objectives.
