Senior Chief Petty Officer

Senior chief petty officer (SCPO) was an enlisted naval rate, a type of military rank used by the service organizations of different cultures. As a traditional naval grade, SCPO was senior to a Chief Petty Officer, and was almost the highest enlisted grade in organizations.

When there are individual grades of chief petty officers, SCPO was subordinate to Master Chief Petty Officer (MCPO).

This rank was considered to have the responsibility of a "noncommissioned officer." Personnel of this grade could be addressed simply as chief (or more properly, "senior chief").
