What project 634922 buys
This project develops and demonstrates advanced liquid rocket engine technologies, components, engines, and integrated systems for launch vehicles. Characteristics such as environmental acceptability, affordability, reliability, responsiveness, reduced weight, and reduced operation and launch costs are emphasized. The objective is to reduce costs, simplify manufacturability, increase performance and life/reusability, as well as payload lift capability. Additionally, this project investigates and demonstrates technologies that will improve responsiveness and resiliency of space access systems and launch infrastructure. This project also develops and demonstrates solar electric, electric, chemical, and advanced propulsion technologies, for station-keeping, repositioning, and orbit transfer for satellites and satellite constellations. This effort develops technologies for flexible, responsive in-space maneuver in all orbit regimes. These technologies are critical to expanding Space Force's capability to deliver capabilities resiliently and responsively in, to, and through space. This project further develops and demonstrates the next generation of physics-based modeling, simulation, and analysis (MS&A) tools for rapid and agile space access and in-space propulsion design, analysis, and production, as well as the digital engineering concepts to manage the entire process of design, test, and validation of space access and in-space systems. This project secures National Unique Testing Assets, providing unmatched capabilities that underpin technological leadership and ensure the safety and security of our nation. All efforts in this project contribute to the sustainment and growth of the space and rocket propulsion industry, providing space access and in-space propulsion technology for the entire Department of War (DoW). Technologies under this project enable capabilities of interest to DoW, National Aeronautics and Space Administration (NASA), and growing Space community. The efforts in this project are reviewed by a DoW level steering committee annually for relevance to DoW missions, and the associated support costs.
Project 634922 funding, FY2025–FY2031
Prior years are actuals, the budget year is the request, and the outyears are the FYDP plan. Estimate types are colored and never summed into one figure. Projects carry the full five-year plan; the activities inside them stop at the budget year.

|---|---|---|
| FY2025 | Actual | 15.3 |
| FY2026 | Enacted | 19.7 |
| FY2027 | Request | 17.6 |
| FY2028 | Outyear | 18.4 |
| FY2029 | Outyear | 18.9 |
| FY2030 | Outyear | 19.3 |
| FY2031 | Outyear | 19.7 |

The R-2A exhibit — the only level of the budget that describes work that has not happened yet. Activities carry the prior, current and budget year only, no five-year plan. 1 of them describes FY2027 work in enough detail to have its own page; the rest are shown here in full. Coverage is partial across the corpus, so count activities, never total them.
Continue: -Develop, demonstrate and transition experimental, modeling, simulation, and theoretical efforts for advanced thruster development with emphasis on flight logistics and thruster lifetimes for rapid and agile design of spacecraft propulsion options. Activities include development of models for total on-orbit asset lifetime based…
