Input: Question: In what year was the Women's Royal Naval Service founded? Passage:In April 1941, Drummond joined the Women's Royal Naval Service (WRNS) and served as a writer (equivalent in rank to able seaman). She was commissioned as a third officer (equivalent to sub-lieutenant) in October, with seniority from 25 September. She was promoted to second officer (equivalent to lieutenant) in October 1942, with seniority from 29 August 1942, and in early 1944 joined the staff of Commander-in-Chief, Plymouth. She was "responsible for the administration and paperwork relating to the command's role in operation Neptune": as such, she was the first woman to learn about the Normandy landings. In April 1944, she was made an acting first officer (equivalent to lieutenant commander) with seniority from 5 April; this promotion was confirmed in August. After the Normandy landings, she was posted to India, where she worked as assistant secretary to its flag officer. Then, with promotion to superintendent (equivalent to captain), she joined the staff of Commander-in-Chief, East Indies Fleet.
