What project 643732 buys
SDA is rapidly developing and demonstrating next generation space capabilities for the joint warfighter enabled by proliferation of satellites in Low Earth Orbit (LEO) and expedited acquisition model utilizing rapid spiral development. SDA is developing capabilities to address a wide range of Department of War (DoW) space needs that align with the United States Space Force Space Warfighting framework and includes space-based battle management and a ground support infrastructure. SDA will orchestrate the rapid development and fielding of the Proliferated Warfighter Space Architecture (PWSA), a resilient military sensing and data transport capability via a proliferated space architecture in LEO. This program element funds the development and demonstration of space technologies to deliver space-based command and control, tasking, mission processing and dissemination capabilities, as well as an integrated, resilient network of ground support capabilities, to U.S. joint warfighting forces in bi-annual tranches, which began in FY 2022.

|---|---|---|
| FY2025 | Actual | 95.2 |
| FY2026 | Enacted | 87.5 |
| FY2027 | Request | 5.6 |
| FY2028 | Outyear | 4.6 |
| FY2029 | Outyear | 2.9 |

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. Coverage is partial across the corpus, so count activities, never total them.
FY2027 planned work Due to the classified nature of this project, specific details are available at a higher classification level.
FY2026 to FY2027 change Due to the classified nature of this project, specific details are available at a higher classification level.
FY2026 plans — current year Due to the classified nature of this project, specific details are available at a higher classification level.
FY2027 planned work Tranche 0 - Conduct residual experimentation in support of PWSA WFOV Risk Reduction. - End-of-life fleet operations.
FY2026 to FY2027 change FY 2027 decreases from FY 2026, reflecting end-of-fleet operations for some Tranche 0 space vehicles.
FY2026 plans — current year Tranche 0 - Continue to leverage operating Tranche 0 satellites to investigate potential developmental capabilities. - Continue to characterize high-resolution background clutter in wide range of spectral bands. - Continue to demonstrate Wide Field of View (WFOV) performance and cost that enables proliferation.
