This new book tells the remarkable story of the design and construction of the many merchant ships that not only contributed to their country’s war efforts, but were also responsible for a cultural change in world shipbuilding that would lay the foundations for the post-war industry. Some of the story has been told piecemeal in a range of diverse books and articles, a few with extensive fleet lists; however, the complete history of the twentieth century wartime-built standard merchant ship has not previously been written, so this new volume recording that history within its appropriate technical, political, and military background will be hugely welcomed.The book includes ships built in Canada, Japan, Germany, and other countries.
