What project MS1 buys
The Battalion Mortar System Modernization project supports the development of modernized Mortar Weapon Systems to support Mobile Brigade Combat Teams (MBCTs), Infantry Brigade Combat Teams (IBCTs), Stryker Brigade Combat Teams (SBCTs), and Armored Brigade Combat Teams (ABCTs). Efforts include development and qualification of modernized mortar systems and their required components to include fire control and ammunition that will increase range, lethality, survivability, mobility and readiness. The weapon and fire control will be used as a standalone man-portable system with digital fire control capability or as a modular system that can be hosted onto light tactical vehicles such as the High Mobility Multipurpose Wheeled Vehicle (HMMWV), the Infantry Squad Vehicle (ISV) and/or Joint Lightweight Tactical Vehicle (JLTV) when a mobility kit is utilized. This modernized system will increase survivability, maneuverability, and provide tactical advantage to the Warfighter when matched with pacing threat for direct and indirect fire and will provide overmatching capabilities. Initial characterization efforts will establish a firm foundation for proposed advanced indirect fire systems while allowing for incremental improvements and updates as technologies continue to mature, which will maintain and enhance performance, improve lethality, responsiveness, and reliability of indirect fire systems across the required spectrum of military operations. Fiscal Year (FY) 2027 funding will support the design and development of a next generation mobile mortar weapons, fire control systems, and mobility kits that can be hosted on tactical vehicles.

Project MS1 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 | 5.8 |
| FY2026 | Enacted | 28.3 |
| FY2027 | Request | 26.1 |
| FY2028 | Outyear | 15.9 |
| FY2029 | Outyear | 12.4 |
| FY2030 | Outyear | 5.8 |
| FY2031 | Outyear | 5.8 |
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 funding in the amount of $26.121 million will continue to support activities to further design and develop a next generation 81mm mortar weapon, fire control system, and mobility kit that can be hosted on a tactical vehicle. Additionally, funding is required to support the next generation 120mm mortar weapon, fire control system…

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.
