Thompson Special Assistant to the Director of the Applied Physics Laboratory. The Johns Hopkins APL Technical Digest is an unclassified technical journal published quarterly by APL. The objective of the publication is to communicate the work performed at the Laboratory to its sponsors and to the scientific and engineering communities defense establishment academia and industry. Founded on March 10 1942-just three months after the United States entered World War II-APL was created as part of a federal government effort to mobilize scientific resources to address wartime challenges. APL was assigned the task of finding a more effective way for ships to defend themselves against enemy air attacks. The Laboratory designed built and tested a radar proximity fuze that significantly increased the effectiveness of anti-aircraft shells in the Pacific-and later ground artillery during the invasion of Europe. The product of the Laboratory's intense development effort was later judged to be along with the atomic bomb and radar one of the three most valuable technology developments of the war. On the basis of that successful collaboration the government The Johns Hopkins University and APL made a commitment to continue their strategic relationship. The Laboratory rapidly became a major contributor to advances in guided missiles and submarine technologies. Today more than seven decades later the Laboratory's numerous and diverse achievements continue to strengthen our nation. APL continues to relentlessly pursue the mission it has followed since its first day: to make critical contributions to critical challenges for our nation. Johns Hopkins APL hardcover
