Naval Glossary

When a person becomes a crewmember of a ship or naval station, the person must learn a whole new type of language that is related with the daily life of a sailor. Many terms and words, probably more than any other type of job in the world, are unique to the Navy and the life of a Sailor. In fact many of the terms and words we use today in everyday conversions can trace their roots to the nautical heritage. This page will help familiarize the visitor with the terms and words that you may encounter in the USS Oregon website.
