Specific military ap-plications of the tran-sistor must, of course,remain classified, but anappreciation of itspromise in military usecan still be had, as thefollowing exampleshows. In World War II, radar played a very important part, uses, large and small, for transistors.Today, aircraft bomb sights are built Reliability, small size and weight, lowaround radar.
