## What project EU6 buys

The 155 millimeter (mm) High Explosive (HE) Rocket Assisted Projectile Extended Range project supports the Army's Field Artillery modernization objectives. This venture develops an innovative rocket design with a lethal warhead that is compatible with unguided and guided fuzes to meet extended range and accuracy requirements. The Next Generation Rocket Assisted Projectile (NGRAP) development effort will first deliver a solution to increase ranges from 30km to 40km in current 39 caliber systems and will also improve accuracy, lethality, and ranges utilizing 39 caliber and extended range cannons. Fiscal Year (FY) 2027 funding will support critical verification testing and qualification activities required to achieve Critical Design Review (CDR).

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

## 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.
