What is the unofficial motto of the U.S. Navy?

The unofficial motto of the U.S. Navy is "Non sibi sed patriae," which translates from Latin to "Not for self, but for country." This phrase captures the spirit of selflessness and dedication that is central to naval service. It emphasizes the commitment of Navy personnel to prioritize the needs of their country over personal interests, reflecting the values of honor, courage, and commitment that the Navy seeks to instill in its members.

The other phrases listed, while relevant in various contexts, do not carry the same historical significance or recognition as the unofficial motto. "For God and Country" suggests a broader patriotic sentiment and faith-based commitment, but it isn't exclusive to the Navy. "All Hands on Deck" conveys urgency and teamwork in naval operations, indicating the need for all crew members to participate. "Fair Winds and Following Seas" is a traditional maritime blessing wishing good fortune to sailors but does not encapsulate the overarching mission and philosophy of the Navy in the same way.

Thus, "Non sibi sed patriae" stands out as the phrase that most accurately represents the values and ethos of the U.S. Navy personnel.
