About the Training & Readiness Accelerator (TReX)

The Training and Readiness Accelerator (TReX) expedites development, demonstration, and delivery of prototypes to increase Warfighter readiness. With a focus on modeling, simulation, and training, TReX provides the United States Government with an agile mechanism to iterate and refine critical technologies to keep pace with ongoing and emerging challenges. By actively incorporating structured operational user feedback, TReX will identify and develop innovative solutions to inform materiel procurement requirements and acquisition.

TReX is a new era public-private partnership that is managed by the National Security Technology Accelerator (NSTXL). Utilizing a broad innovation platform, TReX brings a first-of-its-kind capability to the U.S. Department of Defense. The Accelerator operates as a highly efficient, open-source network of top innovators across the innovation ecosystem, including industry, academia, investors, laboratories, and government. TReX provides support and engagement across the full life cycle of innovation from problem definition to ideation and solution prospecting through technology development and delivery.
