Software, Simulation, Systems Engineering and Integration Directorate (S3I)

The technology experts who put state-of-the-art software into Soldiers’ hands.

Cost-efficient, time-saving modeling and simulation testing that ensures the technology does what it’s supposed to do, when it’s supposed to do it – each and every time.

Our Software, Simulation, Systems Engineering and Integration Directorate develops and delivers responsive aviation and missile total life cycle systems engineering, prototyping, cyber, software, protective technologies, and systems simulation engineering to enable readiness and ensure transformation of the U.S. Army to optimize joint Warfighter capabilities at the point of need.

S3I is also the home of AvMC’s Prototype Integration Facility (PIF) – the premier provider of rapid response and integrated hardware solutions. Established to design, fabricate and integrate hardware, the PIF strives to meet the most compelling and urgent needs of the federal government and its allies.

Comprised of a highly skilled, credible, and diverse workforce, S3I is responsive to customer requirements: cost, schedule, and performance.

“Whether you’re the engineer, or you’re turning a wrench at the PIF, writing a novel piece of code at two o’clock in the morning or running a hardware-in-the-loop run for the thousandth time because the weapon system has to perform in the field the right way every single time, or you’re part of business operations doing the contracts and the budgeting, we at S3I take this mission very seriously.”
Dr. Stephanie Reitmeier, S3I Director
