The Army Swimming Association was formed in 1920 to manage and organise Pool Swimming, Water Polo, Diving for the Army. In 1923 the ASA became the Army Swimming Union so as to distinguish it from the National Governing Body the Amateur Swimming Association (ASA). In recent years the ASU has assumed responsibility for Open Water Swimming as a discipline and now manages the Army as a whole – Regular and Reserve for all aquatic sporting activites.
The Army Swimming Union competes competitively in all disciplines and has recently sent Swimmers to Auckland NZ for the World Masters Games in 2017, and has identified Turin European Masters 2019 and Japan 2021 World Masters as future opportunities.
The ASU is extremely proud that the Army Ladies Swimming Team are the Army and UK Armed Forces Sports Team of the Year 2017.
