After World War II, some fifty bombes were retained at RAF Eastcote, while the rest were destroyed. The surviving bombes were put to work, possibly on Eastern bloc ciphers. Smith cites the official history of the bombe as saying that "some of these machines were to be stored away but others were required to run new jobs and sixteen machines were kept comparatively busy on menus." and "It is interesting to note that most of the jobs came up and the operating, checking and other times maintained were faster than the best times during the war periods."
