Document Introduction

This report is the official FY 2023 Defense-wide Operation and Maintenance (O&M) budget estimate document issued by the U.S. Department of Defense (DoD). It focuses on the fund allocation, operational planning, and strategic implementation for the administrative and enterprise-wide service activities of the Office of the Secretary of Defense (OSD), covering budget execution and planning data for fiscal years 2021-2023. The report's core revolves around OSD's key functions such as policy formulation, planning, resource management, and program evaluation, clarifying the allocation logic of budget funds across departments, programs, and special initiatives.

The report details the budget configurations for OSD's major subordinate offices and core programs. This includes granular data on civilian compensation and mission funds for over 20 core units, such as the immediate offices of the Secretary and Deputy Secretary of Defense, the Office of the Assistant Secretary of Defense for Legislative Affairs, the Chief Digital and Artificial Intelligence Officer (CDAO), and the Office of Cost Assessment and Program Evaluation. Budget funds primarily flow to critical areas such as civilian personnel salaries and benefits, mission support, infrastructure maintenance, and technological innovation, reflecting the support for core defense functions.

The total FY 2023 budget request represents an increase of $332,777 thousand compared to the FY 2022 enacted level, which includes $48,348 thousand for price growth and $284,429 thousand for program changes. The budget prioritizes support for multiple strategic initiatives, including key areas such as the implementation of recommendations from the Independent Review Commission (IRC) on Sexual Assault in the Military, the formal establishment and operation of the CDAO office, climate resilience and energy security, enhancement of facility physical security, biodefense and pandemic preparedness, and strengthening supply chain resilience.

Through multi-dimensional data such as financial summaries, performance evaluations, and personnel allocations, the report systematically presents the rationality and strategic orientation of the budget allocation. The performance evaluation section sets clear metrics for core areas including acquisition and sustainment, financial management and control, intelligence security, and information technology. Examples include the percentage of funds for priority facilities under the REPI program and the material availability rate for logistics system modernization, providing quantitative assessment standards for budget execution effectiveness.

As a top-level financial planning document of the U.S. Department of Defense, this report not only demonstrates the resource allocation logic within the defense administration and operations domain but also reflects the priority directions of U.S. defense strategy in cutting-edge fields such as digital transformation, artificial intelligence application, and risk prevention. It provides authoritative data support for researching the execution of U.S. defense policy and resource management.
