What project BY1 buys
50x228 millimeter (mm) family of ammunition is a critical technology development in response to the Next Generation Combat Vehicle (NGCV) Abbreviated Capability Development Document for weapon qualification, platform integration, and fielding of the XM30 Combat Vehicle primary weapon system (XM913). This effort includes the development of three capabilities: The XM1202 Target Practice with Tracer (TP-T); the XM1203 Armor Piercing Fin Stabilized Discarding Sabot with Tracer (APFSDS-T); and the XM1204 High Explosive Airburst with Trace (HEAB-T). The training cartridge will allow the Warfighter to train in a cost-effective manner and the tactical cartridges will provide enhanced lethality at increased ranges when engaging personnel threats in the open, defilade, and under the cover of urban structures, Anti-Tank Guided Missiles (ATGM) teams, and current and projected future peer armored materiel threats. This effort is operating under Major Capability Acquisition (MCA) authority for rapid prototyping to qualify the three munitions in order to support the NGCV Cross Functional Team (CFT) timeline for First Unit Equipped (FUE). Fiscal Year (FY) 2027 funding supports Developmental Test and Evaluation (DT&E), Milestone documentation, Live Fire Test and Evaluation (LFT&E) and preparation activities for prototype fielding. The total cost of the Next Generation Combat Vehicle Ammunition (NGCV) Middle Tier of Acquisition effort is $122.610 million RDT&E from FY2021 to FY2025. The program is fully funded across the Future Years Defense Program (FYDP).

Project BY1 funding, FY2025–FY2027
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 | 6.0 |
| FY2026 | Enacted | 9.8 |
| FY2027 | Request | 15.2 |

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 supports Developmental Test and Evaluation (DT&E), Milestone C documentation, design optimization, and preparation activities for prototype fielding.

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.
