What project FI4 buys
This funding line is directly aligned to the Army Air and Missile Defense Modernization Priority. The Maneuver Short Range Air Defense (M-SHORAD) SGT STOUT systems add commensurate mobility and survivability to the maneuvering forces through protection against enemy air threats. The system consists of existing capabilities integrated onto a Stryker A1 Double-V Hull (DVH) Infantry Carrier Vehicle (ICV). The Reconfigurable Integrated-weapons Platform (RIwP) and Mission Equipment Package (MEP) house multiple missile and gun effectors integrated onto the Stryker A1 DVH vehicle. For FY 2027 funding enables the development and implementation of performance upgrades, product improvements, obsolescence mitigation, TADSS development, software upgrades, and requisite testing for SGT STOUT systems. Additionally, funding allows for the initiation of Increment 4 to include: capability demonstrations, hardware/software risk reduction activities, and support for market research. The total cost of the SGT STOUT Middle Tier of Acquisition (MTA) Rapid Fielding (RF) effort is $1,732.5 million from FY24 to FY26, including RDT&E ($41.9M) and procurement ($1,690.6M) of prototype units. The remainder of the SGT STOUT MTA RF is fully funded across the Future Years Defense Program.

Project FI4 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.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 21.6 |
| FY2026 | Enacted | 13.7 |
| FY2027 | Request | 43.0 |
| FY2028 | Outyear | 45.6 |
| FY2029 | Outyear | 23.8 |
| FY2030 | Outyear | 17.6 |
| FY2031 | Outyear | 17.9 |
1 accomplishment / planned program
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. Each 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.
FY 2027 will initiate the development of a TADSS (Training Aids, Devices, Simulators and Simulations), diagnostic troubleshooting tools and ongoing product improvement development.

Performers named in the R-3 exhibit under this project. Share is of the project's whole FY2027 R-3 total — the same denominator the program-element split uses, so the two read on one scale and will not sum to 100% when unnamed or government work is in the mix. Budget-justification contract funding, not obligations.
