Differences in Defense Bills Advance in House and Senate, Key Points to Observe for the Air Force
The 2026 National Defense Authorization Act (NDAA) in the Senate is advancing with significant budget boosts for the Air Force and Space Force, surpassing their initial requests. The Senate Armed Services Committee's version of the 2026 NDAA authorizes around $915 billion in total defense spending, with at least $221 billion allocated for the Department of the Air Force.
The Air Force and Space Force initially sought $211 billion but aim for $250 billion through additional funding mechanisms already partly secured in a related tax-and-spending package signed into law on July 4, 2025. Senate lawmakers have approved nearly $61 billion for Air Force procurement and $57 billion for research and development, including investments in priority programs like the E-7 Wedgetail aircraft and Sentinel missile system.
The Senate bill also requires the B-21 to employ nuclear gravity bombs within 180 days after the fleet is declared ready for initial operations, and the Long-Range Standoff Weapon within two years after the B-21 or the missile achieves initial operations. Furthermore, the bill dictates that Sentinel missiles must be operational by October 2033, and that the Air Force should have no fewer than 400 ICBMs on alert at any given time except when transitioning between the current Minuteman III missiles and the new Sentinel fleet.
The bill also adds $149 million to accelerate the design of the Air Force's new nuclear-tipped Long-Range Standoff Weapon and create a conventional version of the missile. The Senate bill withholds a quarter of the Department of the Air Force's 2026 funding until the Secretary of the Air Force reverses changes to the Louisiana-based command.
Congressional support for these increased budgets reflects concerns that previous administrations’ budget proposals underestimated the level of security challenges faced. This has led Congress to push for more robust funding, especially for modernization, procurement, and military aid, signaling a stronger financial commitment to both the Air Force and Space Force for 2026.
The 2026 NDAA in the Senate also includes provisions to codify the role of Air Force Global Strike Command and protect it from other commands that could encroach on its job. Additionally, it authorizes an additional $2 billion, for $4.6 billion in total, for the troubled Sentinel program. The House version of the bill would add just $400 million, totaling $3 billion next year.
The Air Force's Joint Air-to-Surface Standoff Missile procurement could total $650 million next year under the Senate bill, an increase of $322 million over its request. Both chambers endorse the new B-21 Raider stealth bomber's $5.7 billion base budget request for 2026, on top of the $4.5 billion the program received earlier this month to speed up production.
As the 2026 NDAA moves forward in the legislative process for further negotiation and final approval, it is clear that the Air Force and Space Force are set to receive substantial funding increases, positioning them for significant modernization and expansion in the coming years.
