This book presents a detailed assessment of the role of navies in the Korean War. It highlights that, despite being predominantly a land war, navies played a vital part. Moreover, the naval war was not solely a U.S. operation. Smaller navies from many countries made important contributions both in supporting the United States and carrying out independent and combined naval operations. This subject holds special importance since current Western strategic thinking and capabilities emphasise the necessity of combined naval operations involving multiple navies in any potential future naval conflict. The example set by the Korean War therefore offers valuable insights into the operational and strategic problems, and benefits and opportunities of contemporary and future combined coalition naval operations.
