These records were created to document enlisted Navy personnel assigned to each and every discrete Navy command (known as "activities" in Navy terminology), such as ships, aviation squadrons, air stations, bases, stations, training centers and schools, flag staffs, and Marine Corps units.
Arranged by two-year chronological subseries (1949-1950, 1951-1952, 1953-1954, 1955-1956, and 1957-1958), followed by single-year subseries (1959-1971). Each subseries is arranged by "activity number," a unique number assigned to each ship, unit, and command within the Navy. Each activity's muster rolls are arranged in chronological order by quarter, typically with enlisted personnel arranged by rate and thereunder alphabetically by surname. Beginning in the spring of 1956, officers precede enlisted personnel, with officers arranged either alphabetically by surname or hierarchically by rank. Personnel diaries, which precede each quarter's muster rolls, are arranged chronologically by date.
This collection will be updated with the remaining years soon.
