The Royal Navy's Operational Intelligence Centre (OIC) was a leading user of Ultra intelligence from Bletchley Park's decrypts. Lieutenant Commander Ian Fleming of the Admiralty's Naval Intelligence Division, who later wrote the James Bond novels, was the personal assistant to the Director of Naval Intelligence, Rear Admiral John Godfrey. Fleming liaised with the naval department at Bletchley Park, visiting about twice a month, and was well aware of this problem.
