Torpedo Data Computer

Date:
C. 1940s

In World War II, submarines used a torpedo data computer (TDC) to calculate their firing solutions. The TDC recorded the submarines course and speed. Once an enemy ship was spotted, the periscope was raised and bearing were taken of its position. Later, radar also helped establish the coordinates of the target. This information was set on the dials of the TDC, which computed the angle of the torpedo track and the gyroscope setting before the torpedo was fired.
