In which United States code is the Secretary of the Navy's authority to conduct affairs defined?

The authority of the Secretary of the Navy to conduct affairs is defined in Title 10 of the United States Code. This title encompasses the organization, training, and equipment of the armed forces, which includes the Navy and Marine Corps. Title 10 outlines the roles and responsibilities of the Secretary of the Navy, establishing the framework for naval operations and administration. This legal structure provides the Secretary with the necessary statutory authority to oversee the Navy's missions, manage resources, and implement policies essential for the effective functioning of naval operations.

Other titles do pertain to various aspects of military and defense operations. Title 32 deals primarily with the National Guard and its governance, Title 14 focuses on the Coast Guard, and Title 50 is related to war and national defense, but none of them provide the specific authority regarding the conduct of Navy affairs as Title 10 does.
