The Freedom-class littoral combat ship USS St. Louis (LCS 19) departed Naval Station Mayport on September 13, 2026, to support U.S. Northern Command (USNORTHCOM) in securing the southern border of the United States.

This mission involves collaboration between USNORTHCOM and the Department of Homeland Security to assist U.S. Customs and Border Protection. The primary objectives are to disrupt illicit drug trafficking and enhance homeland security. The USS St. Louis assumes these duties from the USS Cooperstown (LCS 23).

The deployment of the LCS class has been a subject of debate regarding naval strategy and cost-effectiveness. While the program was designed for agile shallow-water operations and has seen successes in counternarcotics, it has also faced criticism regarding its acquisition costs and the long-term role of these modular warships in American naval power.
