What is the primary purpose of the Expeditionary Strike Group (ESG)?

The primary purpose of the Expeditionary Strike Group (ESG) is to create a sustained maritime presence. ESGs are designed to operate in various maritime environments and provide a versatile and capable force that can support amphibious operations, rapid crisis response, and humanitarian assistance. This sustained maritime presence allows the ESG to project power, deter aggression, and maintain security in regions where they are deployed.

By having ships and aircraft that are capable of operating together, the ESG can effectively respond to emerging threats and carry out a variety of missions without the need for extensive preparations or deployments from shore. This adaptability and readiness align with the strategic objectives of maintaining a constant naval presence, where the capabilities can be utilized for both combat and non-combat operations as needed, increasing the U.S. Navy's ability to support U.S. interests worldwide.

Having a sustained presence is vital for engagement with allies, showing solidarity, and enhancing deterrent capabilities, thus the focus on maintaining that presence is central to the ESG's mission.
