An untold story of scientists and engineers who changed the course of World War I Roy R. Manstan's new book documents the rise of German submarines in World War I and the Allies' successful response of tracking them with innovative listening devices—precursors to modern sonar. The Listeners: U-boat Hunters During the Great War details the struggle to find a solution to the unanticipated efficiency of the German U-boat as an undersea predator. Success or failure was in the hands and minds of the scientists and naval personnel at the Naval Experimental Station in New London, Connecticut. Through the use of archival materials, personal papers, and memoirs The Listeners takes readers into the world of the civilian scientists and engineers and naval personnel who were directly involved with the development and use of submarine detection technology during the war.

Airships are the forgotten weapon of World War II. Forgotten Weapons analyzes the development of airships as weapons for antisubmarine warfare, examines how scientists and airmen collaborated to combat U-boats and reveals the little-known accomplishments of airship crews. As William F. Althoff demonstrates, the naval airship logged an admirable operational record during the Battle of the Atlantic, the longest continued armed contest during the war. Their useful deployment depended first, however, on effective collaboration between naval airmen and government-sponsored research institutions, such as the National Defense Research Committee (NDRC). The Battle of the Atlantic saw a race to gain technological advantage German measures met by Allied counter measures with both sides producing various weapons and sensors designed either to destroy or to protect Allied merchant shipping. For the antisubmarine campaign, U.S. contract laboratories devised the magnetic airborne detector (MAD), microwave radar, the Loran long-range navigation systems, radio sono-buoys, and pattern ordnance, all of which were fitted to airships. Key NDRC projects exploited lighter-than-air platforms for airborne tests. Hurried into production, special devices for antisubmarine warfare were fitted onto fleet airships as well as in airplanes and surface forces. The result turned the tide against the U-boat menace and saved countless lives, supplies, and shipping. This book is an invaluable history and reference for readers interested in airships, antisubmarine warfare, the Battle of the Atlantic, and the bygone squadrons of unique airmen who helped defeat the Nazi war on commerce from 1939 to 1945.
