The British Pacific Fleet was the Royal Navy's primary contribution to the direct defeat of Japan in 1945, and is among the most powerful fleets Britain has ever sent into action. With naval supremacy in home waters achieved by 1944, many of the best and most modern ships in the Royal Navy could be sent to the Pacific. Illustrated throughout with dramatic new artwork, 3D diagrams, maps and archive photos, this book explains how the Royal Navy joined the Pacific carrier war, and how the fleet adopted the US Navy's ruthlessly effective fast-carrier doctrine. With ships optimized for short=range operations in the Atlantic and Mediterranean, the British had to rapidly adapt to the long-range, high-tempo warfare of the Pacific, and the story is often one of inspired improvisation. The BPF shared the US Navy's terrifying experience of kamikaze strikes, and famously its armoured carriers proved tougher that their US counterparts. With discussion of the fleet's warships, technologies, organization, and the campaign that it fought, this book is an essential guide to the Royal Navy's role in the victory over Japan.
