SHIELD Dark blue and gold represent the sea and excellence and are the colors traditionally used by the Navy; red is emblematic of sacrifice and courage. The quartered shield recalls the four previous ships named USS PORTER and highlights the four cardinal compass points of the U. S. Navy's worldwide mission. The stars commemorate the battle stars earned in World War II by the second and third USS PORTER. The Aegis shield symbolizes DDG 78's modern warfare capabilities designed to protect our nation and ideals. This shield is red to reflect courage and action. The torch, from the Statue of Liberty, suggests the ship's motto and symbolizes the principles of freedom upon which our country was founded.
The crossed Naval Officers' swords honor David Porter and his son, David Dixon Porter. The laurel, arm and trident are adapted from the United States Naval Academy's coat of arms and highlight David Dixon Porter's tenure as Superintendent and the notable improvements he made to the maritime and academic curriculum. The trident, symbol of sea power, alludes to the Aegis Weapons System. The three tines represent PORTER's capability in air, surface, and subsurface warfare as well as the three military conflicts in which the Porter family served with distinction: the War of 1812, the Mexican War, and the Civil War. The gold wreath symbolizes the excellence demonstrated by both officers and each ship that bears their name.
