Typhoon Computer located at the Aeronautical Computer Laboratory, Naval Air Development Center, Warminster, PA. With its 4000 vacuum tubes, the RCA Typhoon, built to a contract with Navy Bureau of Aeronautics, probably was the largest analog computer ever made. Entered in service early in 1951, after three years of research and development under the direction of Arthur W. Vance, it had been intended for the investigation of complex problems, such as the evaluation of the performances of ships, planes and submarines, up to the design of complete guided missile systems. A staff of nine engineers and mathematicians plus six technicians was required to operate the computer. The problem was set up on approximately 100 dials and 6,000 plug-in connections on the programming switchboards. Output devices included two Electronic Associates Variplotter units and 18 GE photoelectric recording voltmeters, plus a three-dimensional trajectory indicator.
