The '''Automatic Computing Engine''' ('''ACE''') was a British early [[Electronic storage|electronic]] [[Serial computer|serial]] [[stored-program computer]] design by [[Alan Turing]]. Turing completed the ambitious design in late 1945, having had experience in the years prior with the secret [[Colossus computer|Colossus]] computer at [[Bletchley Park]]. 

The ACE was not built, but a smaller version, the [[Pilot ACE]], was constructed at the [[National Physical Laboratory (United Kingdom)|National Physical Laboratory]] and became operational in 1950. A larger implementation of the ACE design was the '''MOSAIC''' computer which became operational in 1955. ACE also led to the [[Bendix G-15]] and other computers.
