Shield - The dark blue and gold represent the U.S. Navy. The eagle's head, derived from the coat of arms of the Monroe family, represents both the heritage of the home Oak Hill for which the ship is named, and also the United States. The compass rose symbolizes navigation and world-wide scope of operations. The anchor represents the trials and tribulations in the life of a sailor. A fouled anchor is the worst enemy. Gold stands for excellence, red for courage and sacrifice, and white for integrity.

Crest - The torch, derived from the Statue of Liberty's torch, symbolizes freedom, and also refers to the protection denoted in the ship's motto. The gold mullets record the five Battle Stars awarded to the first USS OAK HILL (LSD 7) for service in World War II. Gold signifies excellence.

Supporters - The crossed Navy and Marine Corps officer swords symbolizes the ship's united mission with the United States Marine Corps in amphibious operations.

Motto - "Nations' Protector" is a nod to the Monroe Doctrine. "Oak Hill" was the homeplace of James Monroe in Virginia.
