What project DD4 buys
The Armored Multi-Purpose Vehicle (AMPV) is an ACAT IC program designed to replace the Army's Armored Personnel Carrier (M113) Family of Vehicles (FoV) within the Armored Brigade Combat Team (ABCT). The AMPV addresses current and future capability gaps in the Vietnam-era M113 Family of Vehicles by delivering enhanced mobility, lethality, network communication/interoperability, and protection. These advancements are essential for moving personnel and executing key mission roles on the battlefield within the ABCT. Fielding is currently underway and is expected to continue through FY2042. The AMPV Improvement Program focuses on upgrading capabilities for integration and implementation across the AMPV FoV to enhance mission effectiveness. FY 2027 funding of $10.853 million for Project DD4 supports Army-requested changes, as well as the continued development, testing, and integration of the following initiatives: * Composite Rubber Track (CRT): Provides significant advantages over traditional linked steel tracks, including vehicle weight reduction, improved fuel economy, enhanced track and road wheel durability, and reduced soldier maintenance requirements. * Vehicular Situational Awareness: Enhances driver and vehicle commander visibility around the vehicle, creating a safer operating environment. * Counter-Unmanned Aerial System (C-UAS) Solutions: Improves AMPV survivability in contested environments by neutralizing UAS threats. * Predictive Logistics Tools: Utilizes analytics and artificial intelligence to forecast supply chain needs, reducing vehicle downtime in contested environments. * Mission Equipment Packages (MEPs): Enables rapid configuration of the AMPV to meet evolving operational requirements across its five variants. Specifically, the turreted mortar MEP will significantly enhance the legacy mortar solution inherited from the M113 M1064 variants. Additionally, the AMPV Improvement Program supports Army assessments, experimentation, and testing to address emerging requirements that impact the AMPV platform.

|---|---|---|
| FY2025 | Actual | 11.9 |
| FY2026 | Enacted | 9.5 |
| FY2027 | Request | 10.9 |
| FY2028 | Outyear | 10.8 |
2 accomplishments / planned programs
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. 1 of them 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.
Conduct system level integration and engineering efforts to upgrade and design mobility, survivability, reliability, software, and lethality upgrades. Continue trade studies, market surveys, select and demonstrate enhanced AMPV capabilities to include Contested Logistics, C-UAS, CRT, Segmented CRT, Vehicular Situational Awareness, MEPs…
