Methods used to improve reliability in military electronics equipment

Reliable, dependable, electronic equipment for industry and for the Armed Services has always been of prime importance for safety and for economy of operations. However, the rapid growth and the increasing complexity of electronic equipment have contributed heavily to a poor reliability record in military operations, with a resultant heavy drain on skilled personnel and funds for maintenance and supply functions. Indicative of this growth in size and complexity is the increase in electronic tubes used on a destroyer: from 60 in 1937, to 850 in 1944, and to 3,200 in 1952.
