Project history

In days of the First World War in the USA the big number of 110ft submarine chasers has been built. Secretary of Navy Roosevelt (future President) participated in development of building of this huge series on small shipyards. When in 1937 leading particulars of ASW ship intended for patrol in coastal areas and on fleet anchoring were defined, Roosevelt has insisted on return to project of twenty years' prescription, which at building was criticised for the small displacement and insufficient endurance. Perhaps, unique concessions for technical progress were a choice of diesels as main engines and installation of sonar.

Under the FY1938 program three experimental chasers under some differing projects (SC449, SC450 and SC453) were built. SC450 was the experimental boat, built by American Car and Foundry under ELCO design.
