Mathews joined the
Women's Royal Naval Service (WRNS) on its establishment in 1918, and was appointed to the rank of principal officer (equivalent to a
Royal Navy lieutenant commander). She was initially the Unit Officer of the WRNS Training Depot at
The Crystal Palace in south
London; the Depot was wound up immediately after the Armistice was signed in November 1918 as recruitment had ceased and she went on to serve in various posts on the east coast of Britain until demobilisation in 1919. She was reappointed as the director of the reformed WRNS in 1939 with
Ethel Goodenough as her deputy. and Mathews retired in 1947. The Vera Laughton Mathews' Award charity was created on 21 March 1969 with the aim of supporting the education and training of the daughters of former WRNS personnel. The charity was disbanded in 2012. == Political campaigning and journalism ==
