Arrangement: Arranged by subject.

Scope & Content: This series consists of correspondence, memorandums, technical notes, photographs, drawings, and other documentation relating to a design competition for new 54-foot and 70-foot motor torpedo boat (MTB or PT-Boat) designs. The Federal Government issued an invitation for competitive design on July 11, 1938, which closed on September 30, 1938. Twenty-one designers submitted applications for the 54-foot boats, and 13 submitted applications for the 70-foot boats. The competition also requested designs for 110-foot wooden hull and 165-foot steel hull submarine chasers, but most of the records in the series pertain to the motor torpedo boat competition, and a few documents pertain to 45-foot aircraft rescue boats.
