SHIELD
Dark blue and gold are the colors traditionally used by the US Navy. Red is emblematic of valor and sacrifice. The revised star denotes the Medal of Honor, our country's highest honor, posthumously awarded to Colonel Donald G. Cook for his spirit of sacrifice and extraordinary heroism. The gauntlet grasps a broken chain underscoring Colonel Cook's internment as a prisoner of war by the Viet Cong during which he unselfishly put the interests of his comrades before that of his own well-being, and eventually, his life. The swords are crossed to signify the spirit of teamwork, while symbolizing the heritage of the US Navy and Marine Corps. The mameluke represents Colonel Cook's service as a Marine.
CREST
The eagle symbolizes the principles of freedom upon which our country was founded and highlights military vigilance and national defense. The tridents represent sea power and underscore USS Donald Cook's Aegis firepower and the capability to conduct operations in multi-threat environments.
SUPPORTERS
The missiles symbolize vigilance, resolve and battle preparedness, while suggesting the USS Donald Cook's vertical launch capabilities.
