The '''Torpedo Data Computer''' ('''TDC''') was an early [[electromechanical]] [[analog computer]] used for [[torpedo]] [[fire-control system|fire-control]] on [[US Navy|American]] [[submarine]]s during [[World War II]]. [[Royal Navy#1914–1945|Britain]], [[Kriegsmarine|Germany]], and [[Imperial Japanese Navy|Japan]] also developed automated torpedo fire control equipment, but none were as advanced as the [[US Navy]]'s TDC,<ref name=JapanGermany>{{cite book | last = Friedman | first = Norman | title = US Submarines Through 1945: An Illustrated Design History | year = 1995 | publisher = Naval Institute Press | isbn=1-55750-263-3 | pages = 195 }}</ref> as it was able to automatically track the target rather than simply offering an instantaneous firing solution. This unique capability of the TDC set the standard for submarine torpedo [[Fire-control system|fire control]] during World War II.<ref name=computermuseum>{{cite web | title = Analog Computers | work = Lexikon's History of Computing | year = 1995 | url = http://www.computermuseum.li/Testpage/AnalogComputers.htm#Restoration | access-date = 2006-07-03 | url-status = dead | archive-url = https://web.archive.org/web/20120814130501/http://www.computermuseum.li/Testpage/AnalogComputers.htm#Restoration | archive-date = 2012-08-14 }}
