Which of the following statements is true about the CPO?

The statement regarding the CPO's birthday being celebrated annually on April 1 is accurate because this date marks the establishment of the Chief Petty Officer (CPO) rank in the United States Navy in 1893. The CPO rank has a significant historical context and is recognized for its unique leadership role within the enlisted ranks of the Navy. Celebrating this day pays homage to the contributions and the evolution of the CPO community.

The other statements do not hold true as they either misstate historical facts or the structure of CPO positions. For instance, while the Navy has a rich history dating back to 1775, the specific rank of Chief Petty Officer was not established until much later. Additionally, the first female CPO was not appointed until 1977, highlighting a different timeline than suggested. The assertion that CPOs are designated only for enlisted personnel also lacks context, as CPOs specifically denote a rank that is integral to the enlisted leadership structure, rather than being a concept applied outside of that scope. Thus, the accuracy of the April 1 celebration underscores the significance of the rank within the Navy's traditions.
