Kratos described the Spartan engine line as delivering military-grade performance while maintaining affordability and production scalability. The company said the engines are designed to provide thrust, reliability and operational capability at commercial prices.
The Spartan engines are currently supporting multiple customers and platforms across the defense sector. Kratos said it plans to expand production to 3,000 engines next year to meet increasing demand.
The company has already begun internally funded long-lead material procurement and strategic supply chain investments. Kratos said those steps are intended to accelerate delivery timelines, support customer requirements, ensure production readiness and reduce 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. Kratos said the line uses a domestic supply chain that strengthens the U.S. defense industrial base and reduces reliance on foreign sources for critical propulsion technologies.
Kratos said its investments directly support Department of War priorities to replenish missile inventories and expand production capacity for precision-strike weapons. The company said the investments also support efforts to deliver affordable mass across the Joint Force.
The company said proactive investments in manufacturing capacity and supply chain readiness position it to support emerging requirements rapidly. Kratos said expanded Spartan engine production reinforces its commitment to affordable, mission-ready propulsion solutions for U.S. and allied national security objectives.
