TDC (torpedo data computer)
A Torpedo Data Computer (TDC) is a sophisticated navigation and fire-control device used by submarines during wartime, primarily in World War II. It processes data from sonar, periscopes, and radar to track target ships' positions, speeds, and courses. The TDC then calculates the optimal torpedo firing solution, accounting for factors like target movement and water conditions. This helps submarine crews aim and launch torpedoes accurately, increasing the chances of a successful attack. Essentially, the TDC acts as an advanced mathematical assistant, translating real-time sensor data into precise firing instructions to hit moving targets underwater.
