German code breaking in World War II achieved some notable successes cracking British naval ciphers until well into the fourth year of the war, using the extensive German radio intelligence operations during World War II. Cryptanalysis 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 or methods. 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 Britain’s Government Code and Cypher School (GC&CS), based at Bletchley Park.
