In 1941, the Imperial Japanese Navy (IJN) went to war with a marginal anti-submarine warfare (ASW) capability. This was a lamentable state of affairs for a nation dependent upon imports to sustain its war economy. There were only a few purpose-built ASW escorts available at the start of the war and these were augmented by a handful of second-class destroyers and a dozen torpedo boats. Once the magnitude of the threat to Japan's shipping became fully apparent in 1943, the IJN made plans for mass production of ASW escorts. These arrived in 1944, but could not stop the massacre of Japanese shipping by increasingly bold and effective American submarines. This volume will detail the history, weapons and tactics of the IJN's ASW escorts. These include the Momi class of second-rate destroyers, the Tomodzuru and Ootori classes of torpedo boars, and the several types of ASW escorts built from 1937 up to the end of the war.

Launching Osprey's new Fleet series, this is a spectacularly illustrated, concise and comprehensive account of the Imperial Japanese Navy's striking force at the height of its power. The Imperial Japanese Navy (IJN) entered the Pacific War as one of the most formidable navies in the world, and its combat power was concentrated into one force, the Combined Fleet. In the months that followed Pearl Harbor it enjoyed an unrivaled string of victories, shattering American, British, Australian, and Dutch naval forces. This period of expansion and constant victories ended at the Battle of Midway, after which the Combined Fleet was forced onto the defensive. In this book, Mark Stille draws on his decades of IJN research to explain what made the Combined Fleet the fighting force that it was. Packed with superb original artwork, explanatory 3D diagrams and maps, it examines the fleet's doctrine, innovative tactics and powerful warships. It also details the qualities and importance of IJN leadership, logistics, naval infrastructure, and Japan's shipbuilding capability, and gives an account and analysis of the IJN's combat performance during these crucial months – not just in the famous carrier battles, but also exploring lesser-known elements such as IJN amphibious forces and land-based aviation.

Warship Builders is the first scholarly study of the U.S. naval shipbuilding industry from the early 1920s to the end of World War II, when American shipyards produced the world's largest fleet that helped defeat the Axis powers in all corners of the globe. A colossal endeavor that absorbed billions and employed virtual armies of skilled workers, naval construction mobilized the nation's leading industrial enterprises in the shipbuilding, engineering, and steel industries to deliver warships whose technical complexity dwarfed that of any other weapons platform. Based on systematic comparisons with British, Japanese, and German naval construction, Thomas Heinrich pinpoints the distinct features of American shipbuilding methods, technology development, and management practices that enabled U.S. yards to vastly outproduce their foreign counterparts. Throughout the book, comparative analyses reveal differences and similarities in American, British, Japanese, and German naval construction. Heinrich shows that U.S. and German shipyards introduced electric arc welding and prefabrication methods to a far greater extent than their British and Japanese counterparts between the wars, laying the groundwork for their impressive production records in World War II. While the American and Japanese navies relied heavily on government-owned navy yards, the British and German navies had most of their combatants built in corporately-owned yards, contradicting the widespread notion that only U.S. industrial mobilization depended on private enterprise. Lastly, the U.S. government's investments into shipbuilding facilities in both private and government-owned shipyards dwarfed the sums British, Japanese, and German counterparts expended. This enabled American builders to deliver a vast fleet that played a pivotal role in global naval combat.

This fully illustrated study examines and compares the roles of the US Navy submarines and the Imperial Japanese Navy's anti-submarine warfare capabilities during World War II. In 1941 and 1942, US Navy submarine operations in the Pacific were largely ineffective, hampered by faulty torpedo design, conservative tactics, and insufficiently aggressive submarine captains. Eventually, though, a new generation of wartime submarine commanders, combined with reliable torpedoes, new generation boats, improved intelligence, and advanced radar, inflicted devastating losses on Japanese shipping. Antisubmarine warfare was initially accorded a low priority by the Imperial Japanese Navy; the lack of ASW escorts and modern weaponry, and an inability to develop tactics, resulted in devastation to vital convoys, and hampered its ability to deter and destroy enemy submarines. This book explores all these factors, and the role that US submarines played in supporting the major fleet operations in the Pacific Theater, notching up almost 500 patrols by war's end for the loss of 52 submarines to the Japanese. The technical and tactical developments implemented by the opposing sides are documented in detail, including US improvements to submarine design and weaponry and more aggressive tactics, and the Japanese development of destroyer escorts, changes to depth charge design, and improved submarine detection capacity.

Brought to life by the personal accounts of six Navy pilots and one British POW, this is the history of the U.S. Navy airstrikes on Japanese-held Hong Kong. Commander John Lamade started the war in 1941 a nervous pilot of an antiquated biplane. Just over three years later he was in the cockpit of a cutting-edge Hellcat about to lead a strike force of 80 aircraft through the turbulent skies above the South China Sea. His target: Hong Kong. As a storm of antiaircraft fire darkened the sky, watching from below was POW Ray Jones. For three long years he and his fellow prisoners had endured near starvation conditions in a Japanese internment camp. Did these American aircraft, he wondered, herald freedom? Trawling through historic records, Steven K. Bailey discovered that the story of the U.S. Navy airstrikes on Japanese-held Hong Kong during the final year of World War II had never been told. Operation Gratitude involved nearly 100 U.S. Navy warships and close to a thousand planes. Target Hong Kong brings this massive operation down to a human scale by recounting the air raids through the experiences of seven men whose lives intersected at Hong Kong in January 1945: Commander John D. Lamade, five of his fellow U.S. Navy pilots and the POW Ray Jones. Drawing upon oral histories, diary transcripts, and U.S. Navy documents, this book expertly narrates the intertwined experiences of these servicemen to bring the history to life.

On 12 September 1944, a wolfpack of U.S. submarines attacked the Japanese convoy HI-72 in the South China Sea. Among the ships sunk were two carrying Allied prisoners of war. Men who had already endured the trials of Japanese captivity faced a renewed struggle for survival at sea. This book tells the broader story of the HI-72 convoy through the stories of two survivors: Arthur Bancroft, who was rescued by an American submarine, and Charles "Rowley" Richards, who was rescued by the Japanese. The story of these men represents the thousands of Allied POWs who suffered not only the atrocious conditions of these Japanese hellships, but also the terror of friendly fire from their own side's submarines. For the first time, the personal, political and legal aftermath of these men's experiences is fully detailed. At its heart, this is a story of survival. Charting the survivors' fates from rescue to their attempts at retribution, this book reveals the trauma that continued long after the war was over.
