## Summary

Project 673941 — Unified Data Library (UDL) requests $74.3M in FY2027, 45% of the $165.0M requested for program element 1203156SF — a new start, with no prior-year and no current-year money. 1 R-2A activity decomposes the request, 1 new this cycle.

## What project 673941 buys

This is not a New Start. FY 2025-2026 UDL funds are allocated in the Space Situation Awareness Operations (SSAO) Program Element (PE) 1203940SF and in FY2027+ UDL funds transferred to a new Program Element (PE) 1203156SF, Project 673941, Unified Data Library (UDL). The UDL project (673941) supports integration, exploitation, and delivery of Space Domain Awareness (SDA) and other space-related data sources for C2 and battle management of space forces. It focuses on enabling data sharing, establishing the data architecture required to aggregate multi-sensor data for broader use at different classification levels, transforming any-source data into normalized, usable information via data exploitation tools, followed by data handoff to Battle Management Command and Control mission systems to support actual space operations. The UDL will directly connect to dedicated USSF collateral, contributing and non-traditional sensors and systems with modernized interfaces and transport options to broadly expose data. The UDL will be the single source for accessing and managing all data in support of the USSF, providing a central location to find and access data, enabling superior analytics.

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

### Unified Data Library (UDL) — NEW START

Modernize the UDL to support a truly federated data architecture that offers enhanced scalability and flexibility for the Joint Force and allies. This modern architecture will enable the UDL to increase the data volume and number of data sources as new commercial sensors and systems are integrated into the SDA ecosystem. This…

## 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.
