## Summary

This activity requests $26.1M in FY2027, 100% of project MS1, down 7.7% on FY2026. The R-2A exhibit describes it across FY2025–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** 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, and mobility kit that can be hosted on a tactical vehicle.

**FY2026 to FY2027 change.** Net funding decrease of $2.176 million from FY 2026 to FY 2027 reflects the decrease in contract and testing costs associated with mortar system modernization efforts.

## Before the request year

**FY2026 plans — current year.** FY 2026 funding will support the design and development of a next generation 81mm/120mm mortar weapon and fire control system that can be hosted on tactical vehicle when integrated with a mobility system. The systems will be compatible with legacy and future mortar ammunition. Funding will also support procurement of test articles, operational evaluations/transformation in contacts and government testing.

**FY2025 accomplishments.** FY 2025 funding furthered the next generation mortar weapon system development, prototyping and testing for the Infantry Battalion Mortar System (IBMS) to increase range and lethality. FY 2025 funding was used to evaluate commercially available mobility systems and engineer their integration directly onto light tactical vehicles such as the High Mobility Multipurpose Wheeled Vehicle (HMMWV), and the Infantry Squad Vehicle Utility (ISV-U).
