The USOA was established by a number of regional organisations in 1959 after the founding of
Confédération Mondiale des Activités Subaquatiques (CMAS) initially to organise spearfishing teams for international competition. Prior to its creation, national competition in
spearfishing (or skindiving as it was and is still known) and
scuba diving was organised by the National Competitive Skindivers Committee of the
Amateur Athletic Union (AAU). The National Competitive Skindivers Committee has previously established in 1954 as an initiative of both the AAU and the International Underwater Spearfishing Association (IUSA) and was the body representing the United States at the foundation of CMAS. ==Recognition==
