The shipyard names on this site have been made as short as possible to fit in the tables and necessarily exclude information not needed to distinguish between the yards, notably the location of many of them. The full nomenclature of the yards and their locations are supplied in the table below. The names in the site match the "short name" column below, which is in alphabetical order, or if space permits they match the "long name."
A major source on all U. S. shipyards is a massive website created by Tim Colton, a maritime consultant with some 50 years of experience in the business, recently moved to www.shipbuildinghistory.com. As of September 2006 the Colton site had some 570 tables of shipyards and the ships they built.| Short name | Long name | City | State/Country |
