### Project 3255 — Decision Support Tools and AI Development

Established program is the data processing arm using AI/ML to ultimately support the missions and effects for Navy's undersea warfighting capabilities. The workload includes research, development and testing, as well as operations and maintain lines of effort to include civilian, military, contractor support/manpower and their related costs, and capability development.

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| Undersea AI/ML Capability Development | 28.6 | 29.3 | 13.6 |

> R-2A activities carry the prior, current and budget year only — no five-year plan. Coverage is partial, so count them, never total them.

## Where the FY2027 request goes

| Category | Share | $M |
|---|---|---|
| Other / unspecified | 100% | 13.6 |

> R-3 exhibit contract funding, not USAspending obligations.

## Mission & acquisition strategy

New program element (PE) established to align undersea Artificial Intelligence / Machine Learning (AI/ML) capability development and meet OUSD (Intelligence and Security) requirement for Military Intelligence Program (MIP). AI/ML represents an important evolution in computer science and data processing by automating repetitive tasks such as data entry and analysis, mitigating human errors and increasing efficiency and operation productivity. AI/ML is quickly transforming the data gathering and identification process with undersea noise in support of undersea surveillance systems.
