The Blue Star Line was a British passenger and cargo shipping company formed in 1911, being in operation until 1998. Formation Blue Star Line was formed as an initiative by the Vestey Brothers, a Liverpool-based butchers company, who had founded the Union Cold Storage Company to take advantage of refrigeration practices. They developed a large importation business, shipping frozen meat from South America to Britain, initially from Argentina on ships of the Royal Mail Steam Packet Company, and other shipping lines that called at South American ports. The high prices charged for transport by these companies led the Vestey brothers to start to operate their own ships. They chartered their first ships from 1904, and began to buy their own ships from 1909 onwards. The Blue Star Line was officially inaugurated on 28 July 1911, initially using second-hand ships. They ordered their first new ship in 1914, and by the outbreak of the First World War were operating twelve refrigerated cargo ships. These were initially prefixed 'Brod', e.g. Brodfield, Brodholme and Brodland. Ships of the company were identifiable by their red funnels with black tops and narrow white and black bands, with a white circle with blue five-pointed star on the red background. Their hull colours were either black or black with a white band, and red boot-topping. The company supplied beef to allied forces in France during the war, and began an expansion programme after it was over. The name format was altered with the introduction of the "Star" suffix to ship names, starting with Royalstar launched in 1919, later renamed . The company expanded its operations to include services to the Pacific coast of North America from 1920, and Australia and New Zealand from 1933. The Blue Star Line acquired Frederick Leyland and Company in 1935 and operated it as a subsidiary. Blue Star expanded into passenger transport, notably with five liners built in 1926–27 for its new London – Rio de Janeiro – Buenos Aires route. Cammell Laird of Birkenhead built three sister ships: Almeda, Andalucia and Arandora. John Brown & Company of Clydebank built two: Avelona and Avila. The quintet came to be called the "Luxury Five". The five ships also had refrigerated holds to carry frozen meat from South America to Britain. The new service was a challenge to both foreign competitors and the Royal Mail Steam Packet Company, whose Royal Mail Ships had been
