Navies have always been technologically sophisticated, from the ancient world's trireme galleys and the
Age of Sail's ships-of-the-line to the dreadnoughts of
World War I and today's nuclear-powered
aircraft carriers and submarines. Yet each large technical innovation has met with resistance and even hostility from those officers who, adhering to a familiar warrior ethos, have grown used to a certain style of fighting. In
Technological Change and the
United States Navy, William M. McBride examines how the navy dealt with technological change -- from the end of the
Civil War through the "age of the battleship" -- as technology became more complex and the nation assumed a global role. Although steam engines generally made their mark in the maritime world by 1865, for example, and proved useful to
the Union riverine navy during the Civil War, a backlash within the service later developed against both steam engines and the engineers who ran them.
