What project DK7 buys
The 155mm Artillery Propulsion Modernization (Advanced Component Development) project supports the United States Army's Field Artillery modernization objectives by developing and maturing three propulsion system components: (1) modular charge that achieves minimum to intermediate ranges, (2) supercharge that achieves maximum range, and (3) percussion primer that initiates both the modular and supercharges. Development efforts also include the design of packaging solutions required for protection during transportation and long-term storage, digital engineering, test measurement devices and modeling and simulation tools. Design emphasis will shift from Joint Ballistic Memorandum of Understanding (JBMOU) compatibility to down selected Mobile Tactical Cannon (MTC) that maximizes interoperability with foreign allies, ensuring that the components support manufacturability within the National Technology and Industrial Base (NTIB). Fiscal Year (FY) 2027 funding will support continued prototyping and testing of propelling charges, combustible cases, additives, and ignition components to advance technologies that improve propellant effectiveness, extend cannon life, enhance primer and charge ignition performance, optimize system-level handling, rates of fire, and overall propulsion suitability and survivability.

Project DK7 funding, FY2026–FY2028
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) |
|---|---|---|
| FY2026 | Enacted | 10.3 |
| FY2027 | Request | 24.7 |
| FY2028 | Outyear | 13.1 |

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.
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.

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.
