The Anti Submarine Warfare Association

Formerly the TASI and ASWI association.

Welcome to the ASW association official Website. The association was formed in 1955 as the TASI Association in HMS VERNON Portsmouth and was renamed the ASWI Association in 1975 to reflect the changing structure of the sonar branch. In January 2019 after a vote of the membership the name was changed to the ASW Association .
