Despite the fact that for many years the United States conducted detailed planning the Japanese were still able to conduct a successful attack at Pearl Harbor. The 1907 war scare with Japan led to the initiation in America of war planning against the threat of Japanese aggression, and the establishment of a standing American capability at the Army War College, where each year students critically analyzed and recommended updates to standing defense plans. Based on these strategic plans, the Hawaiian Department implemented and developed Joint defense plans for Oahu. Historians have shown that the United States military possessed the intelligence to indicate an impending attack on Pearl Harbor. However, the ability to respond to the attack depended on two things: early warning, and effective defense planning. In 1941, radar—the primary means of early warning—remained a new technology. Radar proved to be effective and correctly detected the incoming attack but lacked the ability to discriminate between friendly or enemy aircraft. This monograph has particular significance given today’s concern in America regarding homeland defense, since the lessons learned from analyzing the cause of the successful Pearl Harbor attack will offer insight to planners working on modern-day concerns like potential terrorist attacks against the United States involving chemical, biological, or nuclear weapons. By determining whether poor planning or lack of early warning and response capability led to the tragedy of Pearl Harbor, this research will contribute to modern efforts to prepare for homeland defense.

From the foreword: WHEN JAPAN ATTACKED PEARL HARBOR on December 7, 1941, and Germany and Italy joined Japan four days later in declaring war against the United States, intelligence essential for the Army Air Forces to conduct effective warfare in the European and Pacific theaters did not exist. Piercing the Fog tells the intriguing story of how airmen built intelligence organizations to collect and process information about the enemy and to produce and disseminate intelligence to decisionmakers and warfighters in the bloody, horrific crucible of war. Because the problems confronting and confounding air intelligence officers, planners, and operators fifty years ago still resonate, Piercing the Fog is particularly valuable for intelligence officers, planners, and operators today and for anyone concerned with acquiring and exploiting intelligence for successful air warfare. More than organizational history, this book reveals the indispensable and necessarily secret role intelligence plays in effectively waging war. It examines how World War II was a watershed period for Air Force Intelligence and for the acquisition and use of signals intelligence, photo reconnaissance intelligence, human resources intelligence, and scientific and technical intelligence. Piercing the Fog discusses the development of new sources and methods of intelligence collection; requirements for intelligence at the strategic, operational, and tactical levels of warfare; intelligence to support missions for air superiority, interdiction, strategic bombardment, and air defense; the sharing of intelligence in a coalition and joint service environment; the acquisition of intelligence to assess bomb damage on a target-by-target basis and to measure progress in achieving campaign and war objecti ves; and the ability of military leaders to understand the intentions and capabilities of the enemy and to appreciate the pressures on intelligence officers to sometimes tell commanders what they think the commanders want to hear instead of what the intelligence discloses. The complex problems associated with intelligence to support strategic bombardment in the 1940s will strike some readers as uncannily prescient to global Air Force operations in the 1990s.," Illustrated.

By the start of the 20th century, the U.S. Navy had developed a fledgling salvage capability. Today, under the aegis of the Supervisor of Salvage, the Navy routinely handles assignments around the world, guarding U.S. naval and maritime interests and responding to requests for assistance from our allies. Mud, Muscle, and Miracles takes its reader on a journey through the evolution of salvage--from the construction of a cofferdam to reveal battleship Maineat the bottom of Havana harbor in 1911 to the use of side-scan sonar and remotely operated vehicles to recover aircraft debris and complete vessels from the depths. The story is one of masterful seamanship, incomparable engineering, and absolute ingenuity and courage. It is also the history of one of our nation's longest-lasting public-private partnerships--that of the commercial salvage industry and the U.S. Navy. The second edition updates U.S. Navy salvage history through the beginning of the 21st century and chronicles 18 additional, precedent-setting marine salvage and deep-ocean recovery operations.

Using previously unreleased documents, the author reveals new evidence that FDR knew the attack on Pearl Harbor was coming and did nothing to prevent it.

This anthology discusses the converging operational issues of air base defense and counterinsurgency. It explores the diverse challenges associated with defending air assets and joint personnel in a counterinsurgency environment. The authors are primarily Air Force officers from security forces, intelligence, and the office of special investigations, but works are included from a US Air Force pilot and a Canadian air force officer. The authors examine lessons from Vietnam, Iraq, Afghanistan, and other conflicts as they relate to securing air bases and sustaining air operations in a high-threat counterinsurgency environment. The essays review the capabilities, doctrine, tactics, and training needed in base defense operations and recommend ways in which to build a strong, synchronized ground defense partnership with joint and combined forces. The authors offer recommendations on the development of combat leaders with the depth of knowledge, tactical and operational skill sets, and counterinsurgency mind set necessary to be effective in the modern asymmetric battlefield.

Today we associate the Renaissance with painting, sculpture, and architecture—the “major” arts. Yet contemporaries often held the “minor” arts—gem-studded goldwork, richly embellished armor, splendid tapestries and embroideries, music, and ephemeral multi-media spectacles—in much higher esteem. Isabella d’Este, Marchesa of Mantua, was typical of the Italian nobility: she bequeathed to her children precious stone vases mounted in gold, engraved gems, ivories, and antique bronzes and marbles; her favorite ladies-in-waiting, by contrast, received mere paintings. Renaissance patrons and observers extolled finely wrought luxury artifacts for their exquisite craftsmanship and the symbolic capital of their components; paintings and sculptures in modest materials, although discussed by some literati, were of lesser consequence. This book endeavors to return to the mainstream material long marginalized as a result of historical and ideological biases of the intervening centuries. The author analyzes how luxury arts went from being lofty markers of ascendancy and discernment in the Renaissance to being dismissed as “decorative” or “minor” arts—extravagant trinkets of the rich unworthy of the status of Art. Then, by re-examining the objects themselves and their uses in their day, she shows how sumptuous creations constructed the world and taste of Renaissance women and men.

Based on hundreds of oral interviews and unclassified documents, this study offers a comprehensive chronological narrative of the first four years of Operation Enduring Freedom.

Hold High the Torch, the first of a series of regimental and squadron histories by the Historical Branch, G-3 Division, Headquarters U.S. Marine Corps, is designed primarily to acquaint the members of the 4th Marines, past and present, with the history of their regiment. In addition, it is hoped this volume will enlarge public understanding of the Marine Corps’ worth both in limited war and as a force in readiness. During most of its existence the 4th Marines was not engaged in active military operations, but service of the regiment in China, the Dominican Republic, and off the west coast of Mexico, was typical of the Marine Corps’ support of national policy. In many of its combat operations, the 4th Marines was only one element of a much larger force. In other instances, as in the Dominican Republic and China, the regiment was a subordinate unit in situations which were essentially political and diplomatic. Only so much of these higher echelon activities as are essential to an understanding of the 4th Marines story have been told. This is a regimental history and the focus is therefore on the 4th Marines.
