Legislation moving through Congress for the fiscal year 2027 National Defense Authorization Act (NDAA) includes a provision that limits the Navy’s authority to rename ships. Multiple outlets report that the measure would require the Navy secretary to obtain consent from the Senate before changing the name of a U.S. Navy vessel. The policy is described as appearing in both Senate and House versions of the FY27 defense bills, indicating agreement across the chambers on the constraint. The provision is framed as a procedural safeguard, shifting ship-naming authority from unilateral action by the Navy secretary to a requirement for Senate involvement. The reporting does not identify specific ships affected by the rule, nor does it detail exceptions or the timeline for implementation. As the bills advance, the requirement would apply to any future actions to rename Navy vessels, subject to the final text that Congress adopts and that the President signs into law.
