Army Orders 100 Stinger Training Systems

Cole Engineering Services, Inc. (CESI), a By Light Company, has been awarded a $62 million production contract by the U.S. Army’s Program Executive Office for Simulation, Training, and Instrumentation (PEO STRI) to deliver more than 100 Stinger Training Systems (STS) over the next five years.

This award follows a successful prototyping effort and represents a major step forward in the Army’s modernization under the Synthetic Training Environment (STE). STS is a critical component of the STE’s Live Training Systems (STE-LTS) Increment 1, designed to close live force-on-force training gaps and deliver scalable multi-domain realism.

The STS is part of the CESI Family of Live Training Products, which includes both direct and indirect fire weapons training solutions. Together, these capabilities deliver software-defined, high-fidelity training experiences across a range of operational scenarios, engineered for total situational dominance.

The STS replicates guided munition effects and integrates seamlessly with current Tactical Engagement Simulation Systems (TESS) and STE instrumentation. These ruggedized, interoperable systems will be fielded across Brigade Combat Teams and Combat Training Centers, enhancing readiness through next-generation realism and reliability.

The contract includes delivery, lifecycle support, and plans for integration with future STE-LTS capabilities. By Light has also launched an AI Lab to advance development, testing, and deployment of AI-enabled solutions for defense, cybersecurity, and enterprise sectors.
