## Summary

Project BY1 — Next Generation Combat Vehicle Ammunition requests $15.2M in FY2027, 12% of the $124.9M requested for program element 0604802A, up 55% on FY2026. 1 R-2A activity decomposes the request. Northrop Grumman is the largest named R-3 performer at $6.5M, 43% of the project's FY2027 R-3 total.

**Markets:** Ground Combat Vehicles — matched on the project title only, and no market size is quoted.

## Funding profile

## 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).

**R-3 lines of work:** Product Development; Support; Test and Evaluation.

## Named R-3 performers

| Performer | $M | Share of this project's FY2027 R-3 total |
|---|---|---|
| Northrop Grumman | 6.5 | 43% |
| General Dynamics | 6.0 | 40% |

> Budget-justification contract funding, not obligations. Shares need not reach 100% — unnamed and government work is in the denominator.

## Activities (R-2A) — 1

| Activity | FY2025 | FY2026 | FY2027 | Move | Page |
|---|---|---|---|---|---|
| 50x228mm Ammunition Development | 6.0 | 3.3 | 15.2 | +359% | [a0](https://hitchintel.com/programs/0604802A/BY1/a0) |

> Activities carry the prior, current and budget year only — no five-year plan. In the request year they partition this project exactly; in earlier years they can under-cover it.

### 50x228mm Ammunition Development

## What is NOT on this page

Congressional marks, the R-2 mission description and acquisition strategy, the industry vs government split of the whole request, and related program elements are recorded at **program-element** grain — an NDAA mark lands on a PE, never on a project.
