The thoroughness and versatilityof the Laboratories sonar develop-ment work were demonstrated when,midway through the war, its scien-tists were called upon to change com-pletely the emphasis of their investi-gations. During the first part of thewar, the problem had been one en-tirely of using sonar to combat Ger-man U-boats. With the winning ofthe Battle of the Atlantic, the empha-sis changed to the Pacific theater,where Allied submarines were in theposition that German underseas crafthad occupied in the Atlantic; that is,using sonar on submarines to attackmerchantmen and warships. Circuits have always been one ofthe Laboratories special years before the war, a scien-tist and an engineer teamed up todevelop a circuit that would do sumsin
