Overview
- The Senate Armed Services Committee voted to advance the amendment in an 18–9 split on Thursday, moving the proposal closer to inclusion in the final fiscal 2027 NDAA.
- The House Armed Services Committee already approved a similar provision, and the change follows a 2025 executive order that let the Pentagon use the 'Department of War' label while the department formally requested statutory authorization earlier this year.
- A Congressional Budget Office estimate from January put implementation costs between about $10 million and $125 million and said thousands of federal legal references would need updates.
- Supporters including Defense Secretary Pete Hegseth argue the name would signal U.S. resolve, while Democrats such as Sen. Tim Kaine and Sen. Jeff Merkley call the move unnecessary and a misuse of resources.
- The proposal still must survive full House and Senate floor votes and a House‑Senate reconciliation process before becoming law, so its ultimate fate and the timing of any implementation remain uncertain.
