The purpose of this legislation, known as the "Ensuring Coast Guard Readiness Act," is to allow for exceptions to the current rule that prohibits the construction of Coast Guard vessels in foreign shipyards. This change is intended to enhance the readiness and capabilities of the Coast Guard while considering national security interests. The key provisions of this act include a stipulation that the President can authorize exceptions to the prohibition if it is determined to be in the national security interest of the United States.
