<P> German code breaking in World War II achieved some notable successes cracking British Naval ciphers until well into the fourth year of the War, but also suffered from a problem typical of the German armed forces of the time: numerous branches and institutions maintained their own cryptographic departments, working on their own without collaboration or sharing results with equivalent units . This led to duplicated effort, to a fragmentation of potential, and to lower efficiency than might have been achieved . There was no central German cryptography agency comparable to the British Bletchley Park facility . </P> <P> Instead, each cryptographic department was responsible for cryptanalytic operations .
