Noon to 1p.m., Virtual Program on Facebook Premier
The Naval Act of 1938, also known as the Second Vinson Expansion Act, was an important legislative act passed by Congress under the Franklin D. Roosevelt administration. The Act officially mandated a 20% increase in strength of the U.S. Navy. The Act came about due to several factors including the Japanese invasion of China, the German annexation of Austria, and the disintegration of the naval treaty system established in 1922 when both Japan and Italy refused to sign the Second London Naval Treaty of 1936. The act was sponsored by Carl Vinson, a Democratic Congressman from Georgia, and authorized the construction of 105,000 tons of battleships. USS Carl Vinson (CVN-70) is named after the congressman.
In this month’s Brown Bag Brief, Historian Shawn Woodford will talk about the 1938 expansion act in the context of the pre-war build up in 1933 and up through 1945. This program is presented in collaboration with the History and Archives Division, Naval History and Heritage Command (NHHC),
