What must the Coast Guard do under its SAR authority?

The Coast Guard is tasked with developing and maintaining Search and Rescue (SAR) facilities as part of its primary duties under its SAR authority. This responsibility ensures that the Coast Guard has the necessary infrastructure, equipment, and personnel to effectively respond to emergencies at sea. By establishing and maintaining these facilities, the Coast Guard is better equipped to conduct SAR operations, which can include searching for and rescuing individuals in distress, responding to maritime accidents, and providing support in various emergencies.

Maintaining SAR facilities involves ensuring that all equipment, such as boats, aircraft, and communication systems, are operational and ready for immediate deployment. It also entails continual training and preparedness of the personnel who will carry out these rescue missions. The emphasis on development and maintenance is essential for the timely and effective execution of SAR missions, which can be influenced by the conditions at sea and the complexities of the scenarios they encounter.

In contrast, the other options do not fully encompass the scope of the Coast Guard's SAR responsibilities. For example, limiting their efforts to only rescuing individuals in international waters disregards the vast range of water areas under their jurisdiction, including inland and coastal regions. While conducting annual safety drills can be a part of their training, it is not a mandated action under their SAR authority
