USA: The "Women Accepted for Voluntary Emergency Services" (WAVES) is authorized by the US Congress as a division of the US Navy. Within their first year, the WAVES will be 27,000 strong.
Recruitment poster for the WAVES (Women Appointed for Voluntary Emergency Service)
The word "emergency" implies that the acceptance of women was due to the unusual circumstances of World War II, and at the end of the war the women would not be allowed to continue in Navy careers. After all, two months earlier the WAAC (Women's Auxiliary Army Corps) had been established, which was an "auxiliary" organization serving with the Army, not in it.
But the WAVES from the very beginning was an official part of the Navy, and its members held the same rank and ratings as male personnel. They also received the same pay and were subject to military discipline.
Almost a year later, on July 3, 1943, the WAAC became the Women's Army Corps (WAC), giving its members military status similar to that of the WAVES.
Obviously, this was the model used to create the WAVES recruitment poster
Within their first year, the WAVES were 27,000 strong. A large proportion of the WAVES did clerical work, but some took positions in the aviation community, Judge Advocate General's Corps, medical professions, communications, intelligence, storekeeper, science and technology.
The WAVES could not serve aboard combat ships or aircraft, and initially were restricted to duty in the continental United States.
