Source Data

All budget data on DoDPOM is derived from publicly available U.S. Government sources. Below is a guide to finding and accessing the raw data directly.

DoDPOM does not sell government data. The data is free and public. DoDPOM provides structured analysis, domain ontology, AI-powered insights, and tools that help defense professionals work with this data faster and more effectively.

A note on naming:In September 2025, Executive Order 14347 authorized the Department of Defense to use the secondary title “Department of War,” and official websites have transitioned to war.gov. DoDPOM uses “DoD” in its branding as this remains the legal name per the National Security Act of 1947 and continues to be widely used in acquisition regulations, contract documents, and industry practice.
