Document Introduction

This report is Report 119-39 submitted to the United States Senate of the 119th Congress, aiming to consider and pass the original proposal of the "National Defense Authorization Act for Fiscal Year 2026" numbered S. 2296. This Act is the core legislative document used annually by the U.S. Congress to establish defense policy, authorize defense spending, stipulate military personnel strength, and set the relevant legal framework. The Senate Armed Services Committee of the 119th Congress reviewed and passed this report on July 15, 2025, and recommended the passage of the bill.

The report has a grand structure, divided into several main parts. The core part (Subtitle A) focuses on authorizations for the U.S. Department of Defense itself, covering everything from weaponry and equipment procurement (such as the Columbia-class submarine, medium landing ships, B-21 bomber, F-35 program), cutting-edge technology research and development (including hypersonics, artificial intelligence, biotechnology, quantum computing), to daily military operations and maintenance, military personnel policy (including recruitment, training, benefits, healthcare), and acquisition policy reforms aimed at improving efficiency and innovation. The report also delves into the optimization of internal organization and management within the Department of Defense, cybersecurity, the building of space warfare capabilities, and security cooperation matters with foreign allies and partners.

The report reflects the Committee's strategic assessment of the United States' current "most dangerous threat environment since World War II," emphasizing the need to counter the "axis of aggressors" formed by China, Russia, Iran, and North Korea. To this end, the total discretionary authorization for defense programs in FY2026 proposed by the bill reaches $925.8 billion, which includes $879.3 billion for the Department of Defense base programs and $35.2 billion for Department of Energy national security programs. This reflects the Committee's intent to modernize the Department of Defense's budget and acquisition processes and rebuild the "Arsenal of Democracy" to maintain U.S. military technological superiority through increased budgets and driving major reforms.

The content of the bill is highly specific, not only containing macro authorizations but also, in the form of numerous "matters of special interest," providing detailed requirements and oversight for specific programs, technologies, and policy directions. For example, the report calls for accelerating the hypersonic attack cruise missile program, assessing limitations of the Navy's unmanned surface vessel program, developing a roadmap for transforming the Air Force bomber force, prohibiting the retirement of the A-10 attack aircraft before a specified date, focusing on small unmanned aircraft system threats and countermeasures, strengthening the defense biotechnology strategy, assessing the resilience of the industrial base (especially ammunition supply chains and hypersonic material manufacturing), and enhancing allied cooperation and deterrence initiatives in key regions such as the Indo-Pacific. These directive contents provide authoritative basis for understanding the priority areas and potential challenges of U.S. defense construction in FY2026.
