 Happy 121st birthday to the Chief Petty Officers. April 1st celebrates the Chief's service and what it means to be a Chief in the United States Navy. The Chief Petty Officer rank was established in 1893 and Senior Chief and Master Chief Petty Officers were established in 1958. Since the beginning, Chiefs have been charged with the responsibility of leading sailors to be their best, ready to carry out the Navy's mission when called upon. The gold-filed anchor represents a culture and a way of life for the Chief Petty Officer. For more information, visit the Naval History and Heritage Command website. From the Defense Media Activity, I'm Petty Officer Brandi Wills.
