SHIELD
Dark blue and gold are the colors of the United States Navy. The shields elements are counterchanged to keep them dominant. The seven aerial bombs represent the date of the attack on Pearl Harbor (December 7, 1941). The three black chevronelles allude to John Finns Navy Chief Petty Officer rank, and the color black recalls that he was the last living Medal of Honor recipient from the Pearl Harbor attack. The trident represents naval authority, and the three spikes stand for the ships multi-mission capability. The blue barbed shamrock against the yellow field represents John Finns naval career and his lineage as a tough American-Irishman who embodied the motto, Status Et Pugno (Stand Fast and Fight).
CREST
The anchor, the color and stars on the winged bomb, and the superimposed star on the bomb are elements representing the Navy Medal of Honor. (As a Chief Petty Officer, John Finn received this award at the start of WWII.) The winged bomb symbolizes John Finns rating of chief aviation ordnance man stationed at Naval Air Station Kaneohe Bay. The 50-caliber rounds recall his manning a machine gun from an exposed position throughout the attack on 7 December 1941. The winged bomb also represents that DDG 113 is the first ship built with the Aegis Baseline 9 Weapon System that allows simultaneous air warfare and ballistic missile defense capability. The twelve shamrocks recall CPO Finns Irish heritage and the numerous times he was hit by enemy fire.
SUPPORTERS
The crossed Navy officers sword and Navy cutlass reflect the fact that John Finn was both an enlisted sailor and an officer in the Navy, and they also represent the teamwork and cooperation of the officer-enlisted crew of DDG 113.
SEAL
