Who is affected and how:

• Members of the Coast Guard: Directly affected by changes in civilian oversight, chain of command, and potential reassignment of roles, reporting lines, and administrative support as personnel and functions move into the new Office of the Secretary of the Coast Guard. Operational practices may change during and after the transition.

• Department of Homeland Security personnel and contractors: DHS will be responsible for preparing and executing the 30-day reorganization plan and for transferring affected personnel, functions, and resources. DHS components that currently support or house Coast Guard authorities may need to reassign responsibilities and budgets.

• Department of Defense components and Navy: The legislation clarifies reporting rules when the Coast Guard operates as a service in the Navy, affecting coordination, operational command relationships, and interoperability during maritime operations under Navy authority.

• Federal agencies and Congress: Implementation requires statutory amendments, regulatory updates, and possible appropriation or budget transfers; Congress will receive the reorganization plan and will likely exercise oversight of the implementation process.

• Maritime stakeholders and public safety partners (indirectly): Any changes that affect Coast Guard operations, readiness, or coordination with other agencies could have downstream effects on maritime safety, search and rescue operations, port security, and regulatory enforcement.

Practical effects and risks:

• Administrative and budgetary transition costs are likely even if no funding is explicitly authorized in the single section; funding and personnel adjustments may be required in subsequent actions.
• Operational disruption risk during transition (realignment of reporting lines, reassignment of staff) unless the reorganization is carefully phased.
• Potential benefits include clearer civilian oversight aligned with other military service governance, potentially stronger policy focus for maritime missions, and clarified DoD-Coast Guard relationships during joint operations.

Overall, the legislation is primarily a structural and governance change with wide-ranging administrative, legal, and operational implications for the Coast Guard and its partner agencies, requiring detailed implementation planning.
