FY2027 NDAA House vs Senate: H.R. 8800 vs S. 4784
TL;DR
The House and Senate wrote different FY2027 defense authorization bills. H.R. 8800 ($1.15T, passed July 22, 2026, 216–212) leans into right-to-repair provisions and shipbuilding, including $500M for a second destroyer. S. 4784 ($1.14T, approved by the Senate Armed Services Committee) never reached the floor after cloture failed 50–46 on July 14, 2026. The chambers must reconcile the texts in conference before anything becomes law.

Where they differ most
- Right to repair. The House bill's right-to-repair provisions push the Pentagon to secure technical data and repair rights — a centerpiece the Senate version treats more cautiously.
- Shipbuilding. The House funds a second destroyer ($500M) and backs Sec. 123 multiyear destroyer procurement; track it all in the destroyer & shipbuilding topic.
- Iran & Middle East language. Competing Iran provisions are a major source of the Senate stalemate.
- Acquisition reform. Both bills extend the portfolio model from P.L. 119-60 — see the acquisition-reform sections.
