## What project 625171 buys

This project develops rocket propulsion technologies for the design, development, and fabrication of strategic systems (including solid boost/missile motors, post boost control, aging and surveillance efforts), and tactical missiles. Analytical and experimental areas of emphasis are propellants, propellant management, combustion, rocket material applications, model-based system engineering, digital design of manufacture and test, test stand live-fire testing, and technology for sustainment of strategic systems. This project develops the next generation of physics-based Modeling, Simulation, and Analysis (MS&A) tools for rapid and agile missile propulsion design, analysis, and production, as well as the digital engineering concepts to manage the entire process of design, test, and validation of solid rocket motors through live-fire tests. All efforts in this project contribute to the sustainment of the rocket propulsion industry, providing rocket propulsion technology for the entire DoD. All efforts are reviewed by a DoD level steering committee yearly for relevance to DoD missions.

## What is NOT on this page

Congressional marks, the R-2 mission description and acquisition strategy, the industry vs government split of the whole request, and related program elements are recorded at **program-element** grain — an NDAA mark lands on a PE, never on a project.
