Radar sets were in place in Pearl Harbor in December 1941 and detected the incoming Japanese bombardment, but unfortunately, the warnings were disregarded. Developed out of the Signal Corps Laboratories at Fort Monmouth, Army radar was first successfully demonstrated in 1937. The Signal Corps had responsibility for one of the most important systems used during World War II – radar. Commanders using field radios could maintain continuous contact with their troops during rapid advances. At its peak strength in the fall of 1944, the Signal Corps comprised over 350,000 officers and men, more than six times as many as had served in the first World War.

More than ever before, success in combat depended on good communications. The scope of responsibilities held by the Signal Corps during World War II was significantly increased from its efforts in World War I. Accordingly, this article will focus on the achievements and contributions of the Signal Corps during World War II. June marks the 160th Anniversary of the establishment of the Signal Corps, while 2020 marks the 75th anniversary of the end of World War II.
