The Heritage Foundation's Defense Budget Tool provides a user-friendly method to aid in both the analysis and transparency of the U.S. defense budget and facilitate more informed debate about how the Department of Defense ought to be directing spending.

Until now, individual line items of the defense budgets have only been published on the website of Undersecretary of Defense (Comptroller) each year. This data is published in disparate PDFs and spreadsheets, with no mechanism for viewing all the data at once.
This tool:

• Provides an itemized accounting of the U.S. defense budget for analysis by national security experts.
• Allows a user to create customizable defense budgets that can be saved and shared for future reference.
• Makes defense budget data more accessible to Americans interested in the composition of the U.S. national security budget.
