A quarter of a century has passed since the wartime Liberty cargo ships were launched in their hundreds to offset the world-wide attrition of merchant vessel casualties. Many scores of them survived and sailed the seven seas for over two decades but the years gradually took their toll and by the mid-sixties the time had come for a replacement workhorse of the deep. And when the big international marine interests made known their wants, it was a Canadian-designed vessel that was chosen for the role. Today, several of these new Freedom ships are in service and every few days another sails away from the shipbuilders in Japan or Spain. With 50 or more vessels already ordered and many more expected, the designers at G.T.R. Campbell (International) Limited's Montreal offices have initiated a fleet of ships that incorporate the latest cargo handling techniques with all the advantages of mass production and standardization combined with the finest in naval architecture. Campbell's, often working in cooperation with Canada's National Research Council, have been responsible for many innovations in shipbuilding and have designed many kinds of vessels including massive icebreakers, oceanographic survey ships, dual-purpose bulk carriers and ocean ferries, and have supervised the construction of ships in a dozen countries. The growing fleet of Freedom vessels, sailing around the world, along the corridors of commerce, are a mark of Canadian maritime technology wherever they are seen.
