 U.S.S. Ross is participating in Sea Breeze 21 and it's an annual exercise co-hosted by Ukraine and the United States as a tangible demonstration for our ability to operate together go to sea together. The objective of Sea Breeze 21 is to bring together all of our NATO allies and partners in the opportunity to enhance our collective war-fighting readiness in the Black Sea region to ensure that this region, like every other international body of water, remains safe and stable and open to the international community. We have nations who are not participating in the Sea Breeze 21 exercise, who are exercising themselves in international waters. And our response to anybody that's operating in international waters is that we expect everybody to operate in accordance with international law and maritime regulations with due regard for safety, just as we are.
