Navy Financial Management Systems Modernization Audit Assessment

GAO-26-107119 Published: Apr 14, 2026. Publicly Released: Apr 14, 2026.

Fast Facts

The Navy has spent billions of dollars on obsolete IT systems. Modernizing its financial management systems is critical to DOD’s goal of getting a “clean” audit opinion—i.e., when financial statements are presented fairly and consistent with accounting principles.

The Navy has made progress, but hasn’t fully followed leading strategic and system migration planning practices. For example, it didn’t have a complete approach for executives to monitor issues that contribute to delays—which could make it harder to modernize systems on time.

Our recommendations address this and more.

Highlights

What GAO Found

In response to its December 2020 acknowledgment that it had wasted billions of dollars sustaining redundant and obsolete IT systems, the Department of the Navy initiated an effort to modernize, consolidate, and retire its systems. The Navy reports that this initiative has resulted in terminating at least 11 legacy systems and saved more than $100 million. In addition, the Navy announced in January 2026 that it had completed its effort to migrate remaining Navy commands to Navy Enterprise Resource Planning, its financial system of record.

Fully adhering to leading practices for strategic and migration planning could strengthen the Navy’s systems modernization. Regarding strategic planning, the Navy met two of three leading practices and partially met one. For example, the Navy demonstrated that the portion of its Navy Financial Management Strategy associated with financial management systems aligned with relevant Navy and DOD-level strategic plans. However, the Navy did not fully implement performance measurement approaches for seven of the nine fiscal year 2025 metrics that it identified for this portion of its financial management strategy.

Regarding migration planning, the Navy met one and partially met three of four leading practices. For example, the Navy’s executive management uses Systems Consolidation Action Plans to obtain status reports and monitor system consolidations. Navy actions to fully comply with the remaining migration leading practices could further reduce modernization risks.

In reviewing the extent to which the Navy established a tracking system to manage progress, issues, and action items, GAO identified at least 111 changes to Navy consolidation plans, including at least 49 system schedule delays. These slippages may limit the Navy’s ability to fully support DOD’s auditability goals.

Why GAO Did This Study

The Department of Defense (DOD) remains the only major federal agency to not achieve an unmodified (clean) audit opinion. Modernizing and consolidating the Department of the Navy’s financial management systems is critical to its ability to support DOD’s goal of a clean opinion by the end of 2028. Attaining that goal would enable informed department officials to be accountable stewards of scarce federal resources needed for readiness and the warfighter.

This report was developed in connection with GAO’s audit of the U.S. government’s consolidated financial statements. It examines the extent to which the Navy’s consolidation and modernization of its financial management systems (1) are consistent with strategic planning leading practices and (2) align with migration planning leading practices.

GAO compared key Navy strategic planning documentation and associated evidence to leading practices in strategic planning. In addition, GAO compared Navy transition plans to migration planning leading practices and agency guidance. GAO also interviewed key Navy program officials.

Recommendations

GAO is making five recommendations to the Navy: four on strategic and migration planning and one on the magnitude of schedule delays and their impact on the critical path to achieving a clean opinion. The Navy concurred with one recommendation; partially concurred with two; and did not concur with two. As discussed in the report, GAO maintains that all five recommendations are warranted.
