The Two-Ocean Navy Act, also known as the Vinson–Walsh Act, was a United States law enacted on July 19, 1940, and named for Carl Vinson and David I. Walsh, who chaired the Naval Affairs Committee in the House and Senate respectively. In what was then the largest naval procurement bill to date in U.S. history, it increased the size of the United States Navy by 70%.[1]
History
Modest naval expansion programs had been implemented by the Vinson–Trammell Act of 1934 and the Naval Act of 1938.[2][3] In early June 1940, the U.S. Congress passed legislation that provided an 11% increase in naval tonnage as well as an expansion of naval air capacity.[4] On June 17, a few days after German troops conquered France, Chief of Naval OperationsHarold Stark requested four billion dollars from Congress to increase the size of the American combat fleet by 70%, adding 257 ships amounting to 1,325,000 tons.[5] On June 18, after less than an hour of debate, the House of Representatives by a 316–0 vote authorized $8.55 billion (equivalent to $146 billion today) for a naval expansion program, that put emphasis on aircraft. Rep. Vinson, who headed the House Naval Affairs Committee, said its emphasis on carriers did not represent any less commitment to battleships, but "The modern development of aircraft has demonstrated conclusively that the backbone of the Navy today is the aircraft carrier. The carrier, with destroyers, cruisers and submarines grouped around it[,] is the spearhead of all modern naval task forces."[6] The Two-Ocean Navy Act was enacted on July 19, 1940.
$150 million for essential equipment and facilities
$65 million for the manufacture of ordnance material or munitions
$35 million for the expansion of facilities
The expansion program was scheduled to take five to six years, but a New York Times study of shipbuilding capabilities called it, "problematical" unless proposed "radical changes in design" were dropped.[8]
