Final answer:
The examination of each Naval ship every three years is likely handled by the United States Navy, with additional oversight and regulation possibly involving the Department of Defense, the US Coast Guard, and the US Environmental Protection Agency, in relation to their particular areas of jurisdiction.
Step-by-step explanation:
The examination of each Naval ship every three years is the responsibility of various entities within the United States military and governmental structure.
According to the mandates to provide and maintain a Navy and to make Rules for the Government and Regulation of the land and naval Forces, the examination of Navy ships would typically fall under the jurisdiction of the departments responsible for the oversight and maintenance of the Navy, which could include the United States Navy itself, the Department of Defense, and possibly other federal bodies such as the United States Coast Guard (USCG) and the Environmental Protection Agency (EPA), which are involved in regulatory aspects concerning naval and maritime operations.
For example, as it relates to environmental compliance, entities like the USCG and EPA play a role in regulating discharges and ensuring ships meet specific ecological standards as mandated by laws such as the National Invasive Species Act. The actual process of inspection may include assessments of a ship's structural integrity, safety equipment, environmental compliance, and operational capabilities, depending on the specific standards and regulations set forth by these bodies.
