## Summary

This activity requests $24.7M in FY2027, 100% of project DK7, up 139% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** Fiscal Year (FY) 2027 funding will support continued prototyping and testing of propelling charges, combustible cases, additives, and ignition components to advance technologies and characterize performance with the down-selected Mobile Tactical Cannon (MTC) Platform.

**FY2026 to FY2027 change.** Increase in funding in FY 2027 due to increase in contract and testing costs associated with planned propulsion component development activities.

## Before the request year

**FY2026 plans — current year.** In FY 2026, funding will support prototyping and testing of propelling charge and ignition components to advance technology for improvement of the propellant effectiveness, cannon life, primer and charge ignition performance, system-level handling and rates-of-fire, and overall propulsion suitability and survivability.

## Funding

| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2026 | Enacted | 10.3 |
| FY2027 | Request | 24.7 |

> Prior, current and budget year only — an R-2A activity carries no five-year plan. It sums exactly into its project in the request year and not necessarily in any other.
