These accomplishments are a testament to your hard work and your profound dedication to providing our Warfighters with the tools they need to succeed.”
Martinez demonstrated a keen understanding of RIA-JMTC’s expansive capabilities, highlighting the impressive ability to simultaneously manage more than 300 diverse projects, ranging from legacy system sustainment to cutting-edge technology development.

“My commitment to you is simple. We will build upon this incredible foundation, embracing data-driven decision making, predictive maintenance and a relentless pursuit of efficiency,” Martinez stated. “Together, we will: streamline processes leveraging Lean Six Sigma principles, aggressively embrace advanced technologies like additive manufacturing and robotics, strengthen partnerships across the Department of Defense and with our industry partners, and fully leverage our full spectrum of capabilities, from initial design and prototyping to full-rate production and lifecycle support.”
He then laid out his vision for the future of RIA-JMTC, built on a foundation of continuous improvement and adaptation.
“We will anticipate challenges, pioneer solutions and maintain the highest standards of excellence to keep RIA-JMTC a cornerstone of military readiness.” Martinez said. “From alloying and casting, to forging and advanced manufacturing, all the way to final delivery, your work ensures Warfighters receive the equipment they need, when they need it.”
He pledged to anticipate challenges, pioneer solutions and maintain the highest standards of excellence.
