OVERVIEW

Petty Officer First Class (PO1) is the U.S. Navy E-6 enlisted paygrade. PO1s are the most senior non-commissioned officers below the Chief Petty Officer mess and are typically the Leading Petty Officer (LPO) of a major shipboard or shore division. The PO1 grade is also the lowest from which a Sailor can be selected for the Chief Warrant Officer or Limited Duty Officer (LDO) commissioning programs.

PO1s wear the rating mark on a crow consisting of an eagle over three chevrons. Promotion to E-6 is competitive and requires the Navy-wide advancement exam, satisfactory evaluations, and time-in-rate.

RESPONSIBILITIES

  • Leading Petty Officer (LPO) of a major shipboard or shore division
  • Mentor and develop the entire division's junior Petty Officers and Seamen
  • Run rating-specific technical evolutions to qualified standards
  • Eligible for Chief Warrant Officer or Limited Duty Officer accession boards

HISTORY

The "First Class" designation has been used in the U.S. Navy enlisted structure since the late 19th century. PO1 is the senior non-commissioned grade in the modern Navy — the next promotion, to Chief Petty Officer (E-7), brings a Sailor across the storied "Chief's mess" threshold and into the Navy's senior enlisted leadership.

PO1 is the typical paygrade from which Sailors apply for the Chief Warrant Officer accession program or the Limited Duty Officer commissioning program.
