Vedetta anti sommergibile (anti-submarine picket boat), commonly abbreviated as VAS and also known in Italy as VAS Baglietto (from the name of the shipyard that designed VAS and built a number of them), was a class of motor torpedo boats that served as coastal anti-submarine patrol boats in the Regia Marina (Italian Royal Navy) during World War II. Several boats that survived the war later served in the post-war Italian Navy.

The boats were officially classified as "anti-submarine patrol boats"[2] and the first 30 boats were ordered by the Regia Marina at the Baglietto shipyards on 3 September 1941,[2] entering service between March and November 1942.[2]

The concept had first appeared in World War I and by the 1940s similar boats served with the US Navy where they were known as the PT boats, and they also had their European analogues in the German S-boots. The VAS were in fact a development of the S-boot, derived from the German-built Orjen-class torpedo boats of the Royal Yugoslav Navy captured by the Italians after the Axis invasion of Yugoslavia.
